My hd2 is losing almost 10 % per hour. If i use wifi to update weather etc in sence it may lose 5% in under 5 minutes~!!
I am sure that is coming from a bad app i am using, causing battery drain!!
Please help, any ideas which it may be??
I have installed both free apps and apps i had bought for my hd as well.
Resco explorer
Fingerkeyboard 2.1
gfreek F_Brians tskbar v5.a (many say that taskbar cause also bat troubles..)\
Pim backup
Resco contact manager

midomi
million dollar pocker
PPC visuals Dusk showcase1.0.1b (because hd2 dont have task manager where i want it to be!)
Thats all!! All installed into main memory..(and of course most of them not active as task never! - only apps that running like taskbar, task manager, resco etc..)
ANY IDEAS WHAT TO TRY??
What I would do in your situation it would be to do a hard-reset and check if the situation keeps the same. If not, I would start to install apps one by one and check which one is doing that.
If i cant find any other solution, yes ill do that. But i want to go the other way round, and simply by unistalling find the problem.
The truth is though that the first 24 hours that i had my hd as stock (no apps, not even my contacts) and only the sence configured the battery was still draining fast..And with little usage i lost 40% in about 5 hours..Still far away from the battery tests from our friend xmoo here in xda..
Other users experience???? Please post here so we can check!
I too am experiencing fast battery drain. Only used for about1 hour and already 77% left.
I am wondering.... if anyone who is experiencing fast drain did not charge their phone for a good few hours upon receipt or if it was used while charging for first time.
in the modaco hands-on review, Paul said his battery improved after a few depletion/charging cycles
Hi all ! How should we do it corectly? Is there a plan? 3 charges of 12 h after complete discharge or something like that?
Thank you in advance !
i don't have the answer but can confirm great battery life. I plugged mine in immediately when i got it and left it plugged i over night. To my surprise, i am getting the best battery live of any htc product ive owned (and that's a lot lol) with pretty substantial use. Now the difference between you and me may be 3g. I live in the states and don't get 3g, also i set mine to gsm only. Maybe try gsm only for a few hours?
I've also turned off auto brightness and have it on the lowest setting most of the time, as it's enough for me and helps get the most out of the battery.
the correct way to get the battery in best possible shape
before first use...charge over night
..then use untill battery is completely empty...
...then load over night again (that means about 10 hours)
you do that 10 times in a raw and your battery will be in the best possible shape. From there, you don't have to do the extremes every time but at the beginning it takes about 10 full charging circles for the battery to use its full potential.

thats complete bull**** on litium ion batteries.
Li-ion doesn't need to do the full charging cicles and deplete the 100% of the battery will damage the battery.
My experience with the HD2 battery is great: I get two to three days with one chargecycle. I have set the networktype on GSM and not on Auto.. I think this helps.

this is the only way I can ever get my handsets to go more than one day! Fine for emails / calendar sync, not so handy for browsing/maps though!
What I do with my mobiles is:
When I open it, I use it till the battery is completly over;
Charge the mobile during 10/12 h;
Then use the mobile normally and charge it whenever I want;
After 1 month, I let the battery get completly drained and then do another full charge.
Altough is LI-ON battery and it has no memory, it's necessary to do a "full" recharge from time to time to "calibrate". Don't know if it's really like that, but it's what I've been doing and it works great for me.
I HAVE 3G ENABLED ALL THE TIME,AND WHEN I GOT THE PHONE I BEGAN USING IT ASAP WITG THE CHARGER ON, TILL 100 percent! Writing from thd phone noe as it... charges!51 percent with almost no usage the last 7 hours! Maybe i ll try the full drain thing! Just to check!
ps. also the typing expirience sucks for me.does the aling screen option works in this kind of screen!?
How's the reception in your area? I had a phone that during night, with only GSM network, drained 30% in my home. But in other areas, 1/2% only.

1) let it charge overnight (8hr+), phone off, straight from socket not through pc usb
2) fully drain the battery then fully recharge. repeat for 2-3 times
3) try flight mode (if there is one), let it idle for 1 hour or more. any drain?
4) go through settings and switch off periodic updates (activesync, weather, email). any drain?
5) remove questionable program(s) and see if it helps
6) worst case scenario, hard reset and check if battery usage is back to normal. then install one program at a time

that's the best way to destroy battery. it is a li-ion: first time it's importante to have fast charge.
wot i do is:
-fast charge and never let the battery die.
in this way, alla my phone have an eccellent battery as the first day.
There must be something corrupted with your device.
I had min in use from Friday noon to Sunday late afternoon (forgot my charger at home):
about 1 hour of phone usage, push mail activated, weather sync (syncs all hours), took 5 pictures (2 footprint and 3 normal in hires) and alarm at Saturday and Sunday morning
battery dropped from 100% to 21% in this timeframe with the above usage. I think this is not too bad

probably you aren't very knowledgable regarding batteries...I am.
altho Lithium-Ion batteries have no memory, they still need to be charged correctly at the beginning to free up the potential.

Can you tell us exactly what is the best charging routine for our phone please. When new and when its been used for a while. Thanks.
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?
adb remount
adb shell rm /system/etc/init.d/02memkill
then reboot.

I'm on the BeHero v1.3.2,m will that command put my phone memory settings back to what they would normally be without the taskkiller?
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

I am currently performing the third step...i really hope this works cuz I am getting really really horrible battery life right now...I get only about 8 hours with ocassional use...like listening to music, browsing, taking pictures, sms.
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
Hi
Battery problem, keeps draining quickly, just by leaving it anywhere. I charge the htc hd2, after not much use... the battery looses charge? I have s2u2 installed any ideas why this would be?
In other words, battery is on 100%. I open it using s2u2 and close it, just random play aroung with the phone. Next minute you know the battery is going lower and lower in matter of minutes. Thats with no phone calls, few text, no music, no games played i think your getting the gist?
This is wierd? anyone else experience this?
Please can some help and advice in the right direction.
thanks.

hi pa49
I have looked at soo many post on xda, but i cannot get to to the bottom of it?
1. Is there any post you might note of, that could possibly put me in to the right direction?
2. also any place you can get extended battery (not the big fat one lol)

you may want to install battclock and check what0s your cpu usage, also disable s2u2, check differences, and whatnot... the only way you can find if it's a software problem or not is by checking with a clean rom.
Usual old boring advice, backup and hard reset, test with nothing installed, if there is the same problem of very high drainage, it's basically a good chance you need to send it back for warranty
I have exactly the same problem. Suddenly yesterday my phone's battery drained and I found my phone switched off, out of nowhere. I charged it for 3-4 hours, and then played some games, the battery was left at 85% and when I woke up today, after 6 hours, it was off again.
So you are suggesting to perform a hard reset and observe the way the battery drains?
Ok, First get the battery working at max capacity by charging it non stop for at least 2 weeks. Whenever you can and wherever you can for as long as you can.
Once you have done that there is a battery monitoring capability built into the charging circuits. You could then allow your battery to drain to cuttoff and then recharge to full again which will accurise the power remaing readout. I never bother with this step as I just use the phone and then recharge as soon as I can again, but, if it's important to you then go ahead, but, don't continually allow the cutoff point to be reached as this will damage the battery.
Now you have maximised the capacity of the battery see how it performs and assess whether you need to take further action.
Installing apps to mem card will eat battery.
Some say leaving apps open will drain the battery. I'm not too sure, but, it's good practice to close them any way.
Finding a clean and pared down cooked ROM will save a lot of power, but, you will have to do your own experimenting there.
After that you could invest in a spare/extended battery, however, I would suggest an external rechargable power pack (Have a look at the juice bar solar pack as it will recharge itself without needing a power socket or USB port (although you can use them!), purely by sunlight. Another advantage is that if you change your phone you still can use the pack with your next device and they will also charge many other devices!
Good luck!
I have my new hd2 leo, and battery seemed to be the main issue for me cause it couldn hold 1working day... but as everybody told its nessesery to charge 1 week to exercise battery for its full potential.. but i did some improvements, did the registry thing with dissablepowersavings dont remmember where found that, and instaled wmpowersaving, for control of 3g 2g data, using 2.12 radio rom, witch is more stable than 2.08 cause i use hd2 for a lot of browsing, and 2.08 was freezing my device.. 2.12 is stable and seems using much less power, i can feel less heat in the back of the case.. tried android... but that was not intterested me... i dont need those 1000ds of apps i need to browse the internet using iris browser.. and now battery easily can hold 2 days with some wifi 3g browsing.. and few phone calls some usage of camera.. witch is poor in dark conditions... so i think battery life is 2days ... and control the 2g 3g networks, turn off location service, turn off data connection.. and the battery for today evening is still 72% after 10 hrs of few phonecalls and a bit browsing with wifi.. some gps navigation i dont even think to buy expanded batery cause i dont like the BACK BIG CASE ... Also i wonder how much power is nessesary to run Micro SD built in card reader... because its a pitty to have 180mb internal memory for progams... if it had 2gb then u install everything in the memory and dont use the sd card reader witch i suppose will save couple of hours of battery.
this issue has been well documented..imo the stock rom battery life is awful lasts up to 24hour on casual use for me..there are cooked roms with better battery life or you could invest in a bigger capacity battery from htc or third party ones on ebay
There is a known issue with the HD2 and microsd cards, when the microsd's filesystem becomes corrupted, causing battery drain.

Ok, so I did a quick test, I turned off the radio just to take that out of the equation.
I ran for two hours, first hour with SD card out and then an hour with it in.
From the log, you see that I am about 6 to 7 mA up until 0945 and then it started to cycle, I dont know why, the phone was in standby the whole time.
I put the SD card back in at 1016 and opened explorer just to access it once.
the cycling continued for like 30 min then settled back down to 6 to 9mA.
So, it looks like the currnt is a few mA higher with the SD card in, but I have no idea why the phone was sucking over 150mA in those four to five reading bursts when I was not using the phone.
What do you think?

hi i am currently running the latest version of android on my sd card-(americanandroid 4-2-11)...i noticed i only get about 3-4 hours of battery life on my phone with wifi, bluetooth off and screen timeout after 30 seconds..i have no active widgets on homescreen and the battery is brand new...what do you think is the problem???
ps.-- i am running a stock tmobile rom with radio 2.08...
SD Builds have bad battery usage, that's a fact. You can always try to flash a newer radio onto your device to improve battery usage, but I don't know if this is possible without problems because of your sim-locked phone. Solution to your simlock:

I also think the battery of your phone is getting "lazy". So you might want to switch to NAND roms (go for gingerbread as it has the best battery life) and maybe get a new battery for your phone.

I ran the AmericanAndroid[3/20/11] and had over 26 hours of battery life among which 18 was of heavy use. I had brightness on minimum(NO AUTO), Screen Time-out was 1 minute, WIFI always on since I don't use my HD2 with a data plan, Auto-Sync, 2G active on mobile network instead of 3G/H.
The reason how I achieved this was because of proper battery calibration. There are a few factors that affect it. The most important ones being the percentage your battery level was at when you first booted into Android how you charge your phone.
Here is what I did to "calibrate" :
1.Charged my phone to 100% for 6 hours straights while it was turned ON.
2. Power off the phone while it is still plugged in and left it to charge for another 15 minutes.
3. Unplugged, removed battery, pressed and held the power button on phone for 5 seconds.
4. Turned the phone back on and once I saw the Boot screen(Android), I plugged it in.
5. Deleted the battery stats file using the following in Terminal Emulator :
Code:
su
(Hit enter)
rm data/system/batterystats.bin
(Hit enter)
Once that's done, use your phone as much as you can. to drain the battery. Let your phone die by itself. Once it dies, keep turning it on until it doesn't turn on anymore. then plug it in and boot into Android as fast as you can. If you repeat this one more time, you should see significant improvement in your battery life.
This "tutorial" isn't mine. I read some of around here itself and found some of it on other forums dealing with battery care. All credit goes to those OPs of those TUTs
same problem here
i would appreciate if someone could explain to me why my battery drops off like this and my signal is so intermitent

Booted into windows for a while?
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

Many thanks! Have pass about three days reading about the battery issues/solutions, and I was getting confused by so many info! Will try it tonight!
PS: Does the jug6ernaut's CWM battery fix works for the Orange 2.3.4 ?

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.

lol yes. I used video playback to drain mine. But if it's really a PITA, you can always just leave it till tomorrow to discharge naturally.

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.
