My Son's Nexus 10 had served its purpose. But Started to die at Random percent, Mostly above 50%.. So Got a new Tablet for him. But Did not want to throw away this Gem of a Tablet.
After weeks of Trial and Error finally found a solution Thanks to input from a Redditor.
Issue/Problem: Dies at Random % showing battery %0 and Shutdown. But In Recovery with Full Brightness it does not Die for hours.. (as later found out.. Recovery does not need much CPU power)
So What did I try:
1. Changed Rom's (All the way from Base Google Images to Oreo) >> Did NOT fix the Problem
2. Clearing battery stats.. etc. ( incl completely discharge and Charge and all those cycles usually we do to calibrate the battery) >> Did NOT Fix the Problem
2. Ordered a New Battery - (Samsung Model From Ebay - I guess it was used or who knows ) >> Did NOT fix the Problem
3. Changed Multiple chargers (Wall Adapters/ Cable from multiple brands which i have at home.. LG, Samsung etc etc) >> Did NOT Fix the Problem
Solution/ What Fixed:
Thanks to redditor.. Who mentioned about CPU power consumption.. And Old Mother board might not be providing enough Power to CPU. (As this tablet is Old.. It was just an Hobby to make it work and Did not want to spend more money on MotherBoard)
By this time I was on Marshmallow Linage OS Rom.. (As Everything works), Gave Root access to one of the CPU app's and Did this..(See Below) Enabled on Boot to keep the same settings.
Setting the CPU max to 1200MHz and Min to 200 it WORKED! I tried every damn thing before. For some reason... this idea did not strike my brain. So its the Power consumption from CPU.
EDIT 1: after some more testing You can go upto MAX 1600MHz (Your mileage may vary)
Finally Battery drained till zero without shutting down.
LET ME KNOW IF THIS FIXED YOUR TABLET TOO.. If you have the same issue as mine. (I Know many had this issue like mine.. but none had solution) Hope this helps.

I used below app (But u can use any CPU app).. But other than those above setting(s).. I DID NOT change anything else. But u need ROOT to make that change.
Good Luck. hopefully it helps you too.

Unfortunately at the moment I don't solved the problem, even if I set the cpu min to 200 and max to 1200.
I've installed a new ROM, deleted the cache and still the problem persists. I will do other tests trying to recalibrate the battery.

Humm... Anyway @1600 mine died at 30% .. So made it 1500 and past below 18% and Still running. So I guess 1500 is max I can go
Also Before coming this conclusion: I did the fowling
Charge 100%
Delete Batterystats.bin
Run this command from adb "adb shell dumpsys batterystats --reset"
And then Changed the CPU max (Please NOTE , Select "On Boot" to keep the same parameters). Once u change the CPU settings .. Reboot and see .. if its keeping the same settings.
Many thanks. I tried all of the the things you tried and setting the cpu max frequency is the only thing that worked.
I could get away with seeing it to 1600.
Deleting batterystats.bin does nothing https://www.xda-developers.com/goog...-battery-stats-does-not-improve-battery-life/

Streetmart you absolute legend. I'd never thought I'd see the day my Nexus 10 would drain down to zero again. I tried 1600, then 1500, to no avail; then I said screw it I'll just go down to 1200 (with little hope of it working).
It feels so weird to actually have an internet “solution” work. I'm super happy. I didn't want to buy another tablet. I love this one and it worka perfect for what I use it for.
Thank you! :good::highfive:
OMG! thank you for this thread! i was just posting to look for a replacement for my 10... i hope this fixes it BTW.. what's the normal max cpu speed? I REALLY don't want to replace it as the new dropbox 3 device thing really screws me..

I think the normal is 1700MHz. It's what the program showed before I changed it. All the best! Keep us updated.

What a difference... i installed that a few days ago, and i haven't used my N10 much but on standby it's still at 99% usually it would be WAY lower.. i think that program did more than just lower the max cpu a little.. don't care though. the N10 lives on!!
If you still have this issue, I have been updating the kernel and also found some of the power control settings needed tweaked. Disabling "opportunistic sleep" "logging time spent in suspend" and enabling "advanced power controls" seems to do the trick. had an issue where the device would shut off if battery level reached 20%. Haven't had it happen again yet.

I'm currently running at 1600 with this guy modified kernel and wow, besides no more suddenly shutdowns it runs very smoothly, it reminds me the pre-marshmallow age of this tablet.

I have replace the battery of my N10 because of low capacity.
Now it charge from 0% to 52% then it goes to 100%. On discharge it goes from 100% to 46% then shutdown and battery shows 0%. Percentage is the same in TWRP.
Since replacement of battery it have aroud 10 charge/discharge cycles without any changes.
Any solution for that?

I have to agree on, that the N10 chipset/cpu/powersupply has degraded somewhat & as the battery voltage gets lower during discharge, it can not supply stable power any longer :crying:
If i reduce the CPU speed from 1700MHz to 1200MHz I get to go down to 20% instead the N10 shutting down abruptly at just 30%
I do have a spare battery in the fridge for later on. Once I open up the N10, I'll see if there is a capacitor or two, that could replaced in the power supply area to possibly fix the issue.
Note:
1. On second full charge since lowering the CPU to 1200MHz the battery got down to 14% & I have decided to charge it instead of letting it die at some point at a lower percentage
2. I should have mentioned earlier, that I still use the original N10 battery & plan to replace the original battery with a new aftermarket battery later on if I need to.
3. I use the N10 in an air-conditioned room for no longer, than half an hour at a time only browsing & reading articles with a short 10min video from YouTube.
4. Before lowering the CPU clock from 1700MHz to 1200MHz, the tablet consistently has shut down abruptly, at 27-30% battery level to my dismay.
5. Tried complete battery drain / cache reset to 0% in Recovery mode & then fully charging it while shut down 3 times without success.
6. So far lowering the CPU clock has made a difference & for prof now I am evaluating the N10 battery capacity with AccuBattery.
7. I charge my devices at around 20-25% or higher up to 80% to prolong battery life using apk's to stop charging or alert me.
I have switched to the UNOFFICIAL Resurrection Remix for Nexus 10 (ResurrectionRemix-M-v5.7.4-20161208-manta) MM ROM after rooting my N10 (Danke schön Corinna ) & had to update the baked in Kernel Adiutor.
Installing from APKMirror the "Kernel Adiutor (ROOT) 0.9.73 beta (Android 4.0.3+)" has allowed me to lower CPU MAX Frequency and have it stick after BOOT!

I don´t think so. The capacity of new battery looks really good. I use the N10 as wall-mounted control tablet for my home. With activated DT2W, full brightness, showing cams on motion, controlling home and audio over the day, my new battery runs about 28 hours before it stops. With old battery it was around 15-18 hours from full to off. My workaround: Reading battery with tasker and starts charging at 50%
I think the china batterys have different voltages than samsung batterys and N10 can´t work with this.

Hey,
That sounds very interesting. I may find out about that, when I replace the original N10 battery to my replacement battery from China.
I forgot to mention in my post earlier, that I am still using the original N10 battery. The original N10 battery keeps crashing at 30% unless I lower the CPU clock to 1200MHz.
After the first charge at (1200MHz max CPU) I got the N10 down to 20%+ before crashing to shut down & after the second charge I got it down to 14% at the same 1200MHz without crashing to shut down & just recharged it. Mind you I was just surfing the net & watching YouTube. I am also using AccuBattery to estimate the battery capacity atm. (Oh & don't install Battery Charge Limiter, because it boot-loops the N10 after install!)
DT2W sounds awesome. Which ROM are you using on your N10 to get DT2W, if you don't mind me asking?

Sometimes it shuts down at 20% and other times it won't. I'm almost pretty sure it doesn't have anything to do with advanced power settings or any kind of internal power settings with the kernel. There are no thermal configurations on this device and they don't add any drivers for it or support for it until much later versions. Heat seems to play a role especially down here Florida when outside. So far in my experience it's most likely to shut down at 20% if it's too hot and not likely to do so if it's been idle for a bit or not plugged in.

I was pondering possible reasons for the battery life problem that many of us are well aware of. Some peoples batterys will last a good day or two and then theres people like me who charge my phone in the morning and when i get home in the afternoon just to keep it alive and this is compared with people using the same rom. So i thought maybe there could be something to do with what the battery level is when the phone is rooted or a new rom flashed, and this process may reduce the battery cycle to a specific point. E.g. if i 1st root and load my new rom on my phone at 50%, when booted it could show 100% but its actually 50% than it should be. i have not tested this but im just putting it forward as an idea. if anyone does have the time to unroot, charge to 100% and then reroot their phone + custom rom and test the battery life could they please post their results here. No harm in trying ...
EDIT:It seems we have found a solution or alteast a way to greatly improve battery life by putting my random idea and the information from maxisma togethere.. here are the following steps:
1. When the battery is low e.g. 10% boot into recovery mode and wipe->battery data
2. Reboot and then drain the battery or let it die (turn on mobile network add the 'sync now' widget and keep syncing with the music on loud - works pretty fast)
3. Leaving the phone dead put it on charge and let it charge fully till the led indicates green (may take longer than normal)
4. UNPLUG!! the charger then boot the phone up and your battery life should be much better
TIP!! Remeber when changing and flashing new roms to unplug the phone from charge after you boot!
Hope this works for you all PM me for results (i went from 5-10% loss an hour to what is now about 1-2% max )
Nice idea but almost certain your wrong
Edit: turns out that you shouldn't boot your phone while charging after all
I've think it's more likely to do with how I charge my phone. If I charge the phone on my PC then the battery lasts me a day. On Sunday night I charged it with a mains charger, and a day and a half later I still have 40% left. That's with constant WiFi, Talk, calls and text messages.
Sometimes I'll do the same things mentioned above and the battery will be about 20% by the time I'm going to bed.
I could be very wrong, I'm no battery expert!
There shouldn't be any difference between PC charging and mains charging. The mains charger would utilise a transformer to give the same oomph as a PC gives...if not it'd fry the battery whilst charging.
Funnily enough, mains AC - DC transforms are a little choppy, although at such a low current it should be entirely negligible, but your PC's power supply should give a cleaner power output than the mains. Are you sure it isn't just a placebo, I still like to think charging my PSP via the mains rather than USB will do it quicker and last longer, since its dedicated

I've heard this theory before. I can't even begin to fathom how this could be possible. I hereby dismiss it as 'rubbish'.
Seriously though, I think it's far more likely to be related to the apps/widgets people are using after flashing the rom. The only thing that differs drastically from build to build is the different apps that people install.
Might be worth those with very crap battery lives sending me an hours worth of logcat. I can do an hours worth of logcat for myself (I never have battery issues), and compare the results.
He's partly right.
Android has a bug that when it's plugged into a charger while booting up, it'll report a higher battery status than it actually is.
This is preventing the phone from charging the battery completely.
So, a recommendation for you: Always unplug your phone from the charger before powering it up.

Since my last post ive drained my battery out. Kept the phone off and charged it fully. It did take longer than normal which could be a good thing. Ive booted it up about 15 mins ago and il post later/tomorrow about how the battery performs now.
WOOO
I maybe jumping the gun a bit here but my phone says an up time of 1hour 27 mins. and normally its about an hour to about 5-10% of battery life and im sorry to say... im still on 100% WOO . I will still report how this lasts through to tomorrow, however i think theres enough evidence to suggest that the method stated earlier seems to fix what seemed to be a 'shortend battery cycle'. Anyone else with a short battery life i advise you to do the same asi have and please feedback to me with any results.. hope this has been helpful
EDIT: Its been two hours now and still 100% woooo
I got escited too bratfink when I had 100% battery for ages while it was in sleep, then I dl'd a few progs from market and whoosh my battery started disappearing faster than expected. Try downloading a few things and you'll see your battry disappearing quicktime.
minfree or ramzswap off could be causing the issue.
I remember before I put that tweak on my phone (when it first came out), my battery life was amazing.
After I put the values in for init.d as from the forum page below:
http://forum.xda-developers.com/showthread.php?t=622666&page=6
the battery life started disappearing like mad! and this was on a modaco rom!
I think now that all the new 2.1 roms are including this minfree tweak it is causing this battery issue to be carried over. All attempts to reduce battery drain are not having as much effect as they could because of this.
I would like to try one of these new roms without the tweak but I do not have the knowhow to stop it. i.e. put the original init.d (or equivalent) for the the roms in place.
You might argue that the memory clearing has nothing to do with the battey drain, but what i saw was that it did on a modaco rom. I don't know whether it is the switching of ramzswap or the minfree settings ( i have a feeling it is both.
Can a chef cook one of their roms without the tweak and keep the original settings?

If so can I just remove that file with OI file explorer as atm my laptop usb aint working (can't connect to phone properly, can only charge)
If you use Bluetooth, GPS*, or plug/unplug usb, CPU lock at 528Mhz and battery drain. This happend in all eris/roms.
I can see with Battery Graph while I sleep the battery is full, but no reason (only unlock to check time, kill alarms, read mail,...) the battery drains constantly. (no tweeter, no facebook, no GPS, no BT,..),
This kernel sucks. It's very buggy but is what is

thanks for posting this thread.
Ill post the results tomorrow ( hopefully positive)
I noticed that using the overclock widget (even with the lower clock option when screen is off) also eats some battery, it definitely reduced my usage time on Android 1.5.
Could someone confirm?
I dont know what it is and why people have this bad battery drain.
I have the VillainRom 3.4 installed. Totally NO drain. I turned on Bluetooth and called several times. Battery drain is 8% in 12 hours .
I did not install any widgets. Pure standard custom ROM with newest radio.

exactly my view.
I'm using HeroDroid and i had really bad battery drain problem. I'm a sort of heavy user and with bluetooth & gps permantly on, my phone had drained out by lunch time. After doing some tests, i have found that my problem was related to GPS. If i boot my phone with GPS off and left it at off, i get the same battery level usage as my original cupcake 1.5 ROM. Perharps you guys can try it and post your results.

I found that to help as well. In the last 3h10m it only went down by 4%. That's definitely a lot better than what I was getting before and with the previous ROM. I am using the new Autokiller and Overclock widget if that helps any and booted up with my GPS off and followed the steps mentioned in the first post.
hmm if its the case that the phone is "capping" the maximum amount of charge the phone can have then it should take longer to charge also
my battery life i kinda okay, lasts 10-12 hours with intermediate use, using battey graph app it took me 70 mins to charge from 40% to 100%
ill let it drain out tonight and see how long it takes for a full charge
it would be good if we could compare results with people with and without battery problems
So, I'm at a loss of what to do here. No matter what settings I seem to use I can't get good/decent battery life.
In fact, I get terrible battery life. With light to moderate usage I have to charge my phone at least two times a day, mostly three. Current widget reads that at standby I'm anywhere between 55mA-70mA and when in use 200mA-500mA. When charging it reaches 400mA-600mA
I see everyone talking about being able to get 5-10mA and I'm amazed at this. I've searched and read most "Battery saver" threads and none of it seems to work.
I was originally using Chucky rom lite and when I noticed the drain was abnormal I switched to the set up that chiasoft uses in his ReadMe for the ROM (stock 2.10ROM/2.08 radio).
Although since switching to the stock WinMo ROM I had repeated BSOD and SOD issues. To the point that it became unusable. I switched over to latest Energy ROM.I installed EBL and on both Stock and this Energy ROM. I am still having BSOD/SOD problems. Could it be the EBL? I plan on upgrading the radio to 2.12 in a few after I test out this EBL theory.
My setup as of this post is this:
WinMo ROM: Energy.BLACKSTONE.21916.Sense2.5.Nov.08 (Switched back to Stock 2.10)
Radio: 2.08.50.08_2 (Switched to 2.12)
Android: MooMoo Froyostone Sense 3.2 w/hastrain kernel
SetCPU:
998max/245min Ondemand on boot
Profiles: Screen off; Priority 100; 384max/245min ondemand
Battery <25% 576max/245min Priority 0 ondemand
Sampling 20000; Up Threshold 40
Advanced Task Killer:
Kill Level Agressive
I really don't want my LI-ON battery to die before I've even had the phone for the year. So if anyone can think of anything to help I'd be ever so grateful.
And of course, thanks to all the people who make all this possible.
(Sorry for the tl;dr post. I wanted to give as much info as possible.)
when you fully charge your batter what is your mV ? use the battery life widget to determine this. If it is not nowhere 4000mV once fully charged, you might need to consider buying a replacement battery.
btw. my mA reading is actually worst than yours. Might have to calibrate the battery again later.

idk what it is fully charged. I'll be sure to check it later though. How do you calibrate the battery?
Also, I realized that I made an oversight on my part. When I switched to the stock WinMo rom I hadn't realized fully that it changed my Radio to 2.08 even though I posted it.
The rom chef recommends 2.10ROM/2.12 Radio, so that's what I switched to to check out that combination.
btw change it to interactive not on demand.
you charge the battery when your phone is off. Till your charge indicator turns green.
Once that is off. you can use root explorer or adb and go to rm/data/system delete the batterystats.bin leave your phone plugged in while you are deleting the batterystats.bin file
i prefer root explorer. but its not free and your device has to be rooted.
let the phone drain the battery till its dead and turn it on again to make sure it is completely dead.
charge the phone like you would usually afterwards.

Just installed 2.04 and there still isn't an interactive.
thats odd. because im on 2.0.4 also and I am able to select interactive.
btw i followed this guide for the battery conditioning.

Yeah. No interactive settings. Also, that guide recommends 1190 max, but mine only goes up to 998.
Also, I finally got it to down to 7mA in standby. When I changed the radio to 2.12 and using a 2.10 stock WinMo rom.
no issues here getting 48 hours of light use, or a full 24 of moderate use...
I've yet to "condition" my battery. I'm worried it'll do more harm than good. Especially since I just got it finally to a decent mA draw. Although I'm worried my phone won't charge up to 100%. Always stop at 95.
Is conditioning really necessary/important?
easy answer... whats your full charge voltage? shuld be 4.2
if not , your looseing batt life..

yes full charge voltage should be around 4.2. Try charging it with the phone OFF till your charge indicator is green. This way you can achieve a full charge.
By the way how the hell are you getting 48 hours on light usage?? excuse my language. What are your setcpu settings, configurations. etc.

Yeah, 48 hours seems improbable. I finally got it down to 7-10mA on standby, and I think it charges up to 4.2 but I'll find out for sure tonight.
same
I had the same problem, make sure you use EBL android launcher and set to autoboot at 3 seconds. Make sure you restart your phone anytime youw ant to load android. I assure you this will work.
My HD2, like all others can be flattened in 2-3 hours with windows/android if used hard, the difference seems to be on very light usage/standby win mobile could last 4 days... with everything turned off and basically not used Android would struggle to last 2 days !
Same phone same network/signal levels etc, can only be poor power management within Android, and I think that means voltages for all the processor and comms modules, not just a simple case of turning down speeds.
What do others think ?
Update: Upon switching to WinMo:2.10 and Radio:2.12+ MooMoo's MMS fixed froystone3.2 I was achieving 6-10mA in standby. The phone would last all day with a two-three hour charging period with moderate usage. Low battery use, rare DC's. Perfect. Best build I've used so far.
I'm noticing a new problem however, and I wonder if it's happened to Chiasoft who recommended this build. I'm getting serious touch screen freezes since last night. Anytime before that the set up was working AMAZINGLY.
Now? It's almost unusable sometimes. This morning it was happening in Android so I switched to WinMo and surprisingly enough it happened in there too. So I read touch freezes are Radio problems mostly. Is this true? Should I switch to a new radio? I'm confused as to why it would just randomly start happening though and worried it would mess up my battery troubles I just solved.
Any advice?
Hmm. I noticed that it almost always freezes when I hold down the end home button to turn off the phone or data or to silence it. I can't actually use the touch screen again until I hit the button again to put it to sleep.
I wonder if it's hardware related because it was happening in WinMo that way as well.
Okay, so now the entire adroid system is acting up mostly related to the touchscreen. Like I use the calculator and it appears that i'm holding a button down. Or I try to make a call and it's not responding. It appears that when I hit end call button repeatedly it allows me to unlock the phone. But when holding down the end call button to get to the Power Off screen nothing in that menu is responsive.
It seems... software related, but I'm not sure. Any info would be helpful. I'm going to reformat my card and reinstall droid and see what happens.
So, called t-mobile. They're sending me a new replacer phone. Oh well. We'll see how that one goes.

I give you only a very short suggestion
You have just to DELETE SETCPU
and delete ANY TASK KILLER (you can keep it just to close any apps that could hang, but not to "free up ram")
Android is not Windows, you dont need to free up ram, and you dont need to overclock/undervolt to gain some minutes of battlife despite stability.
Talk to any Dev and they will confirm this.
Good Luck
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
That's all folks! Please report your success / lack of such here. Also, feel free to ask questions, and I along with other users with answer them according to our ability.
I will later add a section on "good practices for battery usage" with tips and tricks.
Cheers!
Attached are screenshots of my results after calibration: This was under moderate usage. Pretty damn good if you ask me.
Post-calibration methods of improving Battery Life
Updated: Post#2 will explain how to solve battery drainage problems when recalibration wasn't enough. It will also explain how battery reporting works, common practices, tips, tricks, etc.
Battery Tips / Tricks / Common Practices
Important things to know:
1. It's important to understand how battery indicator on Android works and how Android manages / reports your battery life. Please read this article:
Your Smartphone’s Battery Gauge is Lying to You (and it’s not such a bad thing)
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
2. Li-ion batteries used in modern smartphones don't have "charge memory". Partial charges won't hurt the battery (e.g. charging from 60% to 80% or from 10% to 50% etc). Feel free to give your phone small charges whenever you have time and need the phone to last longer.
3. Smartphone batteries don't like to be completely discharged or to be kept at 100% capacity for extended periods of time (this actually damages batteries over time). But worry not, the battery software prevents this from happening for you. That's why some of your phones never get to 100% or drop from 100% to 90% minutes after you disconnct the phone from a charger.
4. All batteries gradually lose a small percentage of their capacity after a certain amount of charge cycles. It's a natural part of life. It's always nice to have a spare battery or to purchase a replacement when your current battery isn't to the task anymore.
5. Don't pay much attention to the battery %, just use your phones. I know it's very tempting to track your battery usage every 15 minutes and try to find problems. Been there myself. Thing is, if you do this, you might start thinking you have problems, when you don't have any.
Bottom line - just try to use your phone and not mess with the battery unless problems become really apparent.
------------------------------------------------------------------------------
Other proven ways to improve Battery Life
If you have re-calibrated to a full capacity (4200mv) but your battery still drains terribly - follow these steps to pin point the problem.
1. Find which app / process is draining the battery.
If you get lucky, the infringing app will show up directly under the stock "Battery Usage" statistics. However, in most cases "Battery Usage" isn't very informative. Most people report that they only see "Phone Idle" consuming most of the battery without much insight into the details.
Things to do:
- install Watchdog, go to preferences, set CPU threshhold to 20% (or even lower if it's not enough), check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20%(or even lower if it's not enough) as well. Run it for a couple of days.
If you start getting frequent Watchdog notifications about a certain app breaching the threshold - uninstall it, find an alternative.
- install BetterBatteryStats from here -
http://forum.xda-developers.com/showthread.php?t=1179809 run it for a couple of days and monitor apps / processes that are using up more wakelocks than they should.
Once you find the infringing app - uninstall it, if it's a process - find out if it's safe to stop / freeze before doing anything.
2. Freeze bloatware aka "stop the problem before it becomes a problem."
Unless you are running CM7, your rom is based on stock 2.3.4 and still has blur in it. Blur apps and processes might be running without you even using them and sucking out precious batter life while they are at it.
Things to do:
- Get TitaniumBackup, freeze all bloatware that is mentioned as "safe" in this thread -
http://forum.xda-developers.com/showthread.php?t=1182663
Use your phone for a couple of days afterwards and watch for improvements.
If these software tweaks aren't enough, the problem might be with your system setup. Go through these steps which should hopefully fix your setup in favor of awesome battery life:
3. Flash a custom kernel, set up battery saving profiles.
Many people have reported success with this step. Custom kernels are not just for overclocking. A custom kernel with smart profiles will definitely give definitely extend your phones operating life during the day.
Things to do:
- Get a custom kernel., the popular choice on here seems to be faux'es kernel, so I recommend it -
http://forum.xda-developers.com/showthread.php?t=1156040
Get one of the battery saving SetCpu profiles along with it. Basically, a good battery saving profile looks something like this:
- absolute minimum CPU clock with screen off (something like 275 Mhz)
- lowering CPU clock with temperature > 50C (something like ~800Mhz)
- lowering CPU clock when battery < 30% (something like ~800Mhz)
Many people reported success in using such profile for lowering "Phone Idle" drain.
4. Flash a different radio.
WARNING: Be extremely careful with this. Flashing a wrong radio is the right way to hard brick your phone.
Although some people are reporting to have fixed battery drainage by trying out a different radio, I seriously wouldn't recommend going on a flashing spree unless you know what you are doing.
My advice here: flash the latest 2.3.4 for your carrier if you haven't yet. From there on, experiment at your own risk.
5. Disable Data and Wifi when idle either manually or with an app."
I seriously get surprised every time someone says they have a horrible battery life, when they keep an internet connection on at all times. Constant data always = battery drain.
Things to do:
- use apps like Green Power to disable data / wifi for you when you are not using it
- learn to turn off your internet connection manually
6. If all else fails - start over from scratch (read: clean install a rom).
I've heard reports of people getting better life with Froyo than GB, or that a specific custom ROM solved their problem for them. A million dollar question: if it works for you, why not use it?
Things to do:
- try a ROM without blur, like CM7
- try Ninja Speed Freak (developer and many users reported great battery life)
- if battery life is your top concern - try Froyo

Click to expand...

Are you using stock Orange 2.3.4 rom?
If yes, your Rom might not have the battery jumping problem. You can still use this guide without the battery fix to recalibrate.
Let's wait for someone with Orange 2.3.4 to confirm if jug6ernaut's CWM battery fix can be used or not.
Indeed, I have not the battery jump issue, but I'm exprimenting some weird behavior...
like when I restart the phone, it shows about 10% higher than before. I tried this multiples times yesterday. When it was about 40%, it starts to drop suddenly, 'till it got to 18% and get back to normal decrease to 4%, 2~3 hours later...
See the images attached, the red circles are the times I rebooted it and the blue arrow is when it drops suddenly...
Question on step 4. To confirm, we shouldn't click on anything in BatteryCalibration, all that needs to be done is take note on the MV number, correct?

Did it only start doing this on 2.3.4 or you haven't checked before? Anyway, I would do the calibration to see if it changes anything.

No clicking in step 4. Just write down or remember the MV number.
Yes it just starts when updating to 2.3.4... In the first days I got the impression of lower battery level, so reading the forums I saw the restart/level change problem, and tested it

You probably updated to 2.3.4 while not at 100% battery level, and it messed up your battery stat. So, yes, do all the steps in this guide except for jug6ernaut's battery fix part.
thanks, ill give this a shot....again.....tonight and hopefully it will fix my issue.

I'm on a rooted stock GB and I'm having the problem where the battery usage stats are inaccurate and won't got below 90% after using it all day. This all started after I used Battery Calibration. Do you think that this would help correct the problem?
Edit: Also, would I need to complete all of the steps including the CWM part? I haven't flashed any roms yet, so I don't know if this would be necessary.

Seems like you used Battery Calibration while not at 100% charge and your battery stats got messed up.
The reason I recommend using CWM is because the battery stats file is created on each boot. So, with my instructions you can charge the phone to 100% while it's off and wipe the messed up stats before it boots.
You can try using my instructions, without the CWM part, except you need to wipe your battery stats with Battery Calibration app after step 4.
lol i left pandora on since this morning and its only at 67%. ugh, when i wanna force drain the battery it goes slow as hell but when i wanna conserve battery live for usage it drains quick. hahaha.
I just flashed navalynt's πCrust rom fully charged, cleared stats through cwm, booted and now i'm close to 3days.

Yep, that's why flashing only when at 100% charge always pays off.
I get the same results by booting to CWM, wiping battery stats, rebooting, starting Battery Calibration, plugging phone into wall charger, charging to 100% (4197mv for me), and then calibrating with Battery Calibration. I start this process at any battery percentage, and have been doing this for a long time now. I have never had to deplete my battery until my phone shuts off, and get great battery life.

After the calibration I had 4200mv, so it seems like you are doing things right in regards to the battery.
"Taking the battery out and putting it back in" trick works wonders though in restoring battery life to maximum state (if you had it decrease for some reason). I've tested it multiple times even back when I had the Milestone.
I am using auroraspv3ce final.
With most of time in sleep with wifi, it goes 8-9 hours.
If i use for example twitter facebook, it goes maximum 4-5 hours.
And mostly applications stop or lag so ihave to stop activity. I am using automemory ptimizer in aggressive mode (100 mb free) but still i have this problem.
For example when someonecalls me, 2-3 seconds waiting, i can see the person name. It shows number first.
What applications do you suggetst or what should i do?
I want to do tests memroy and battery tests to see if something is wrong. How?
I have battery problem too is normal not that much. Did you try to reduce clock speed governor? Interactive is good. Try and report.

Yes of course. Go to menu and run application No-frills CPU control. For example select 806 Mhz for Max.clock and 245 Mhz for Min. clock. Governor you can choose Interactive.

I did, it success but what is that for? To reduce battery? It seems now fast, opening apps, closing.
Yes it's for reduce battery. Namely if you don't play games (like me) that clock is perfect for that purpose. Interactive governor is good too mainly if you don't always need screen on aka idle.
You can test others clock for min and max but that governor is excellent.
so eeez
best way to improve battery live is propper calibration
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
it needs root.
best way to calibrate battery is fully charge then unplug restart device plug in charge till 100% and do it again over and over for 3 times then... calibrate battery
fully discharge and charge again till 100 w/o breaks
also update your soft to soon coming v6 of auroraSP
hope i helpd
Battery Drain Wifi
I have done calibrations and changed clock speeds to no avail, Wifi really chews battery on most ROMs. e.g. Fully charged at 8pm and completely dead when i wake up the next morning.
Might simply be a case of new battery, does poor battery affect phone performance?

Thanks mate, I bought this one shortly before reading your post http://www.trademe.co.nz/Browse/Listing.aspx?id=638683016 only $6NZD
Looking forward to having decent battery life again!
i changed the phones battery i noticed that it is acting weird. i fully charged the phone and this morning i took the charger out and in 30 minutes without touching it it dropped to 95% and from 7 am until 4 am the battery is now at 26% without even touching it. what happens is when i look at it it says that is still 95 but then when i go to settings/battery then it changed to 26 out of nowhere. i tried putting the old battery but still no go.i tried installing a custom rom and kernel and i even tried 4.2.2 stock and 4.3 stock and even changing radio and i looked online for help but same thing happens. i dont know whether is a battery problem or a software or hardware problem. i really need the phone working and i was wondering if someone had the same problem and also if you used to charge the phone with a wireless charging station because i saw something about using it and then not getting enough power from stock charger. i bought it on ebay and the previous owner had a wireless charging if it helps and he told me a new battery would fix the blinking red light of death. any fixes for this? here is the video of the weird battery problem and it is on airplane mode and safe mode. https://www.youtube.com/watch?v=PlFqagJ2v-k here is another video of how slow the device detects the battery drain https://www.youtube.com/watch?v=Blz68xgQcDU
Install the following app:
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
You can find a free version that works just as great but I personally like this. Charge to 100% then just use it normally. After it drains, open up the app and see what wakelocks there are. You can Google them and it'll tell you what to disable or uninstall from there

Last night i went to sleep with 93%, after 8 hours i had 93% but after 5-6 seconds it dropped to 81%.... no sync, airplane mode, greenify on all apps...
I've also bought a new battery... nothing to do... it can be can hardware problem?
Thanks

Well the graph has started from when the phone was at 1.2Ghz... The battery life just doesn't get worse.. Its the same with 1.2 and 1.9.. Just some minor differences.. There is less heat and low performance on 1.2 and on 1.9 the phone heats up quite a bit but the performance also increases considerable.. But it doesn't seem to affect battery life..
Vikram: Firstly, its bad manners to hijack someone else's thread. You should start your own if you have a question.
It's hard to say if it affects a battery life, because your graph is over the span of two days. One single charge and discharge cycle is sufficient to demonstrate any issues. In any case, it may be unrelated to your overclocked processor, I would install the wake lock detector app and start from there.
