Samsung GT-T5800. Android OS 2.1-update 1, I5800XXJH1, Kernel 2.6.29 root SE-S603 #2.
The problem:
1. Battery till 50% discharges normally - about 10-15% per day, but after 50% it immediately shows 15% and asks to connect charger and phone switches off very fast. actually no chance to mane even emergency call. No 40%, no 30%, no 20% in battery level.
2. When connect phone to charger - battery charging level immediately set to 80% or every ~10 seconds: 50%, 60%, 70%, 80%. After that phone charges about 1,5-2 hours till 100% and after about 1-2hours it asks to disconnect from the charger. Battery temperature during charging and after it: 31-33C.
After 3d 8h 40min. (~80hours using applications: Battery booster and Memory Booster, no 3G) of battery usage phone switches off.
Battery usage was:
Android system: 61%
Cell Standby: 19%
Phone Idle: 12%
Bluetooth: 4%
Voice calls: 4%
Time from 15% to 5% - 15 minutes with no using the phone. Battery's temperature 20C, Voltage: 3588mV Phone switches off. I have tried 2-3 times to switch on the phone to make battery more empty and finally switched it on and at the same time connected it to charger.
Here is the interesting charging time line after phone died and was switched on to charge it (sorry - no in seconds):
0:00 - 1% - 20C/3588mV (temperature/voltage)
0:01 - 3%
0:01 - 5%
0:01 - 15%
0:02 - 15%
0:03 - 30%
0:03 - 40%
0:04 - 30%
0:05 - 15%
0:07 - 15%
0:09 - 30%
0:12 - 40%
0:14 - 30%
0:15 - 15%
0:16 - 30% - 28C/3698mV
0:18 - 40% - 28C/3718mV
0:20 - 50% - 28C/3730mV
0:21 - 40% - 28C/3727mV
0:23 - 50% - 27C/3728mV
0:36 - 60% -
0:36 - 50% - 26C/3769mV
0:37 - 60% - 26C/3774mV
0:59 - 60% - 26C/3807mV
1:24 - 60% - 26C/3807mV
2:06 - 70%
2:07 - 80% - 26C/3906mV
2:44 - 90% - 26C/3971mV
3:18 -100% - 25C/4101mV
4:03 -100% - 22C/4184mV - Asked to disconnect the charger.
After this charge GT-I5800 (with no any software changes) stoped to show 50% to 15%, but 30% disappears fast to 15% (it means one short call).
Possible that battery issue reason is that (I think) phone was charged partly switched off and partly switched on.
Maybe there are some battery level controlling OS software bugs, I do not know.
Is it official bug or issue?
Or some guru can comment that battery level issue? I saw I was not first user having it.
should be from the firmware
it seems this happening to all
Well i also have exactly the same issue...
I have observed that when i make/recieve a call the battery voltage decreases greatly because of which the battery also decreases and after sometime the battery voltage comes back to normal but NOT the battery.
My battery also drops down from 50% to 15% or 5%.....It's really very annoying...
I think that this is a frimware issue but i am not sure..I am scared that it could be a hardware issue...
Well i have mailed Samsung also regarding this issue so that they fix this issue in the next frimware upgrade and hope others also do the same so that we have a better chance of this bug getting fixed.....!!!

And when I switch off / on the phone then it shows probably correct vallue. For an example. It shows me 15% and after restart it is 60 %. What a stupid bug - I've never have this problem with any device before. Even phones 10 years ago were able to show correct battery status. I think this problem was also with original 2.1 android firmware.
Can someone who has upgraded to froyo pl. confirm that this issue is resolved in the new firmware?

yes, in JP9 / froyo is still this battery problem. When I switch on / off the phone then it's ok. Does someone resolved this issue please ?
My issue still exists. Froyo did not help. Also I can't understand why does one time on charging battery becomes hot, another time -cold.
same for me, and today i charged my phone and after charging just put it on my table after 1h i saw that there are only 80%. Didn't see this on other firmwares
Same here. I thought it is because of my battery manager widget which I had installed, but un-installing/master clear also did not help. Looks like it is major problem. Moreover, few of the battery widgets mention that in some devices they report 1% level battery change, but in Samsung I5801, it will be 10%.
what about this issue at JPA ?
when you was installing JPA did you hard reset your phone ? (factory settings)
If yes which application do you use for restore all of the datas and settigns ?
Yes, it was done. Hard reset seems is not related, and did not help.
Same problem here...
Since built in battery meter is not accurate at all Im using custom one but problem remains.
might fix battery issue.
might work...saw it for Epic 4g and gave it a shot (as its Samsung too). Some sites say LiON do not have memory like NiCd did but somehow it worked for me. Now I stay on 100% for 5hrs or so. lasting 2 days with 45mins call time and some Wifi use. Like today charged full 100% at 9AM and now its 2230 and I have 80%.I have switched off a lot of things. See below.

Above needs to be done once only. If it doesn't work then go to service center. Remember battery has 6 months warranty only so be quick and try above on new battery.
I also run LauncherPro instead of stock. Disabled data and enable when out of AP range (only use Wifi when needed and have an AP). Background data/synch is always off unless I use market. All apps are set to never except Gmail. Use K9 Email too and ATK. Am on DDj6 FM. Have removed a lot of apps, foursquare included and run 2 screen with LauncherPro widgets only.
Settings to switch off are here.

As long as I know li ion batteries doesnt have the memory effect but they still have to be recalibrated from time to time, lets say once a month. That means dont charge the phone until it goes off and then charge to the top.
I wasnt willing to wait for 11 hours for phone to charge when I bought it and after few days I ve notice that battery last very short. After that I ve performed the full cycle (drain to the bottom - when phone turn itself off, then after few minutes turn it on, wait until it goes off - repeat few times until its completely off then charge it fully - I usually turn off the phone while charging ).
As long as I know all modern devices like phones, notebooks etc shut down before the battery is completely drained because they want to have safe margin of the battery power because of, as long as I know, when li ion batteries become completely drained then could be damaged completely so you cant recharge them again. Anyway with that "turn on then its drained" I believe that I use the battery more than normal and that phone will recalibrate to the new situation figuring that battery have more voltage than phone "expected".
Anyway with few recharging cycles like those I ve described above I can use the phone now for a 2 days with moderate usage...
That 50-15 problem still exist but 100% period last quite long and also phone can be used a long time from the moment battery reach 15% ...
Try doing it the other way round!
Keep your device on constant charge or at least as much as possible for 10 days from new and you should have now problem.
I have run tests on Lion powered devices for the past 5 years and I have never had to "calibrate" once.
My battery usage is always consistent and seemingly accurate.
And this method encourages max power from the battery.

i just flashed my I5801 with Froyo (XXJPB and then XXJPA), but having very low battery back up, can anyone advice something which can help boosting the performance of the battery? Please help.
Hi there,
I'm using P6800 and started experience abnormal on the better.
The battery warning on 15% charge, it will get flat very fast. And when reached 8%, the phone just initiate a shutdown. Had you face this problem?
1 more thing is that when the phone say full charged, once the plug pull off, it show 99%.
Mind is till virgin and unroot...

This is normal, mine is showing the same, but still at 8% upon shut down you can still power it on several times until it reaches 0%.

Mine doesn't do that... If i take my tab off power i have 100% for around 5 to 10 minutes, depending on usage. Also it shuts itself off exactly on 0%. Most of the times I see 0% battery for quite a few minutes before it powers down.
what did you do to make it like that? Rooted?
I'm a rooted stock 3G
My battery stays at 100% for a bit unless i am running some heavy duty processes. However I do also experience the battery going flat very quickly after it goes below 10%. I also found that very odd, and I think it would be at 2% when it initiates the shutdown process.
I would like to hear any thoughts as well on why this might be happening

I didn't do anything to it. Browsing the web on wifi, 3g disabled it goes down to 0% before shutting down. When I play angry birds I can see 0% battery quite a few minutes before it shuts down.
Yes, my device is rooted.

Shutting down on 15% would be normal for a broken battery.
My htc desire shuts down on 2-5% and I thought about sending it for repair. Unfortunately I didn't but now seeing my 7.7 can go down to 0% I think I should have. It is totally not normal for an intact battery to behave like that.
Could you please post how long your battery is lasting on average?
New Galaxy Tab 7.7 Same Battery Issue
I have the same issue with the battery, i tried root and battery calibration; nothing happens. My tablet is brand new it has less than a month.
The battery life is not bad but like other said: Battery get flat after 8%. And its shutdown but you can turn it on several times until you get a complete discharge.
What can i try to solve the problem?. It looks like a bug or software related issue.
Someone has any idea how to fix it?. Thanks!
Does anyone have any idea why this is happening? Started happening randomly about 2 weeks ago on stock 4.3. Switched to PA 3.99 then to CM, still happened. Flashed 4.4 and it died today at about 20%, usually it's around 40%.

Do you get a blinking red light sometimes when you charge it?
Try this for me. When your battery is at 30% try to take a picture with flash. If your phone shuts off then it might be that your battery is bad. From you have said I think the battery is bad. You will need to replace the battery.

you van try this:
1st: Set both max clock and min clock to 1.5ghz(1512 or something mhz).PS use trickster because sometimes setcpu dosent work or it get reverted.
2nd: use your phone normal, until it reaches 0% of battery(i dont mean 0%,what i mean is the state of it dosent even turning on because of low battery,a.k.a flashing red light).
3rd: hold down both volume rocker buttons for 60 seconds and then plug in the charger(if this is right it will simulate that you have removed the battery, you may wanna check if the combination is right, because my n4 is on rma :/)
4th: after that, recharge your phone for at least 6hours(remember: dont turn on the phone while recharging, let recharge with the phone off)
5th: after phone turned on, get back the min clock and max clock to its original value(usualy max 1512 or something and min 384 or something)
6th: profit(if it worked lol).
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.

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.

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.

Yesterday, my battery was running perfectly fine. Today, the battery goes for about 10 minutes on screen time. Getting it charged from 10% to 100% is very quick, maybe takes about 10 minutes. But going from 100%, it can discharge at about 5% per minute, regardless if im using it or not. When I was at 70%, i tried to restart my phone to see if it would fix it, but when It was going to turn back on, i was greeted with the low battery sign, signaling that the phone wasn't able to turn on. 70% = No Battery? Battery drains by 2% per minute when screen is off.
I'm running Lineage OS 14.1 official rom with magisk. Please help.
GSam Battery Monitor Says that 60% of battery is consumed by "Kernel (Android OS)"
Many times i have watched my battery go down multiple percent in a matter of a second its really scary

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones. Near as I can tell the best method is to let it drain till dead - then plug in with your charger and leave for several hours. Power on while phone is still plugged in - let it continue charging another hour.
Use normally. You may need to repeat this a few times.

I've done that about 4 times. It didn't really make a difference... then I used a battery callibration app from the play store which didn't even require a full battery drain or charge and it worked very well... weird.

What app? willing to try next time I have the same issue (about every couple months it would seem)
