My galaxy tab p1000 has just got a voltage jumping problem. When It is full charged, it show ~4,2V (it is normal), but when i unplug, it immediately show ~3,8v - 3,9v, but the percentage still true (show 99%) . And after that, sometimes my tab 's voltage decrease and increase (For example, when at 88%, it show 3,7v, and later it show 3,8v, and later when it 86% it show 3,9v, and then after a few minutes at 86%, it show 3,8v). My tab is fully discharged at ~ 3,1v (it is normal).
So I dont know why my tab got this issue, and I dont know how to fix this.
Can anybody tell me what to do?
Thank you very much!
Corrupted battery stat, try hit the search button.
And if you don't, try the batt calibrator<<<something like that.
What i did when above can't solved the probs, i open my tab, disconnect the batt but not recommended for techy noob.

How I solved my battery drain problem!
Have you tried turning off 3G?
I also had this issue battery drain was huge. It started appearing suddenly one day. Its a very slow process to figure out the culprit. I did a step by step analysis.
1. Found out that battery drain was happening only when 3G was on. Verified this by switching off data network (long press power button to deactivate).
2. Also verified abnormal data usage in my carrier page when I was not using my phone [like - 3G was on and I was watching a movie at a theater].
3. I also saw abnormal battery drain soon after I started Google Maps after a fresh reboot.
4. So I identified the culprit - Google Maps - but was not sure how to solve battery drain [Google Maps restarts, if you kill it].
5. I installed a variety of apps to identify the battery hog. Finally I went for Task Identifier.
6. Task Identifier finally showed me what programs started while my screen was off, etc. And I started noting them. Finally I figured out that Google Maps::BackgroundFriendService was running frequently.
7. A quick search on Google helped me understand that this is about Google Latitude. It searches for your friend's location every now and then - leading to battery drain!!!
8. I opened up Latitude and signed out from it [I guess the sign out option is in Menu -> Privacy].
9. Do not re-open Google Latitude after this - you will get signed in again leading to battery drain.
10. After 2-3 months of search and prodding, I finally figured out the cause of battery drain and fixed it - now I get 2 - 3 days of charge in my battery under normal usage!!
I'm happy now!!
Hi,
If you're using Froyo and can access file in your phone,
In task manager , on the tab "Summary", click on the "start monitoring" button. Let it monitor the phone over the night. The next morning, there should be 2 files created in your sdcard, one is CPUxxxxx and the other one is battxxxxxx.
The Batxxx tells you when the percentage of the battery at certain time of time. the CPUxxxx will tell you wht applications are running during that period.
When i used it first time, i notice that facebook and lattitude always running - when I stop these 2 tasks; i get a normal drain again.
while you guys are at it.
here's my "problem".
when I surf for an hour over 2g I losing about 10% batterylife and android reports that my display uses around 90% to 95% of the battery.
display is set to lowest brightness + screen filter.
is that normal? (im guessing it is not).
used dozens of different roms (stock, darky, jims, etc...), same behaviour everywhere.
i already did all the battery stat wiping and whatnot.
is it a faulty battery or display or something?
for the OP, maybe a combination of the above with this could help :

Sounds normal to me. 10% loss while surfing and 95% display is nothing extraordinary.

My battery status drop significant after unplug from charger. When charge it show 100% full, the moment unplug drop become 81% How to fix this?
i also have the same problem and im getting pretty pissed off, phones plugged in all night, unplug from 100% and it drops to 88%.
meanwhile my battery widget still says discharging from 100% and the time i unplugged the phone at n
It happens to my handset also. This started after upgrading it to 2.3.3 and this behavior i am observing from Day-1 of the update.
The battery drain has increased alot after the update and i am forced to charge the mobile twice atleast in a day.
It is really surprising the big names "SAMSUNG" & "GOOGLE", what they are doing?
Whether the time has come for the GOOGLE to introspect their raise?

Take a look at this:
Battery Drain after full charge with charger connected on a GB OS image
I also happened to me, after a few reserch i found that when you install a custom rom, you have to calibrate battery, so it shows and charges acurrately, you can find lots of info in this forum, or you can try with an app called Battery calibration ROOT RIGHTS NEEDED.
the battery drain issue i found an article saying that it happens when uprgading to 2.3.3, it happened to me, it drained 10% an hour in sleep mode, after the fix it drains 0-5% in a 10h sleep mode.
Android OS bug on Gingerbread ROMs
This is the most annoying Samsung/Android bug.
A good few people have been seeing battery drain on Gingerbread. It comes randomly and apparently once it starts the only way to stop it is to reboot... But it comes back after a while
You can identify this drain by checking the Battery Use in Settings : if Android OS is above 20%, often between 40 and 60% of the battery consumption while your phone has been idle most of the time, then that's it.
The good news is that there is a semi-fix found in XDA: 2 system apps are responsible for this leak, here's what to do using Titanium Backup :
Find Software Update & Samsung Account, select them one by one and "Clear Data". Now you need to freeze Software Update (if you have the Pro version of Titanium Backup) or to backup the app and delete it. Since you don't delete the backup, it's like a freeze. (But keep the backup in case you want it back for some obscure reason)
Or simply use the default app manager to clear the data and Root Explorer to backup/delete Software Update.
If the Android OS battery drain comes back after freezing/deleting the 2 apps above then I suggest you read about the app below. You can back it up and delete it as well and see if it improves:
wssyncmlnps.apk (info) - make a backup in case.
But the AOS BUG will probably keep coming because there is no proper fix to it (Google bug fixed on 2.3.4).
Please share your findings posting in this thread so everybody can know.

if you want the full guide search in darky's rom forum battery life, and its a guide. I cant post links outside the forum bc im new.
Of course you need root access. IT WORKED GREAT FOR ME. I have darkyrom 10.1 w/2.3.3 android. I do recommend to backup Software Update, Samsung account and wssyncmlnps.apk And then delete them. Reboot, and let everything loads correctly. Charge your Phone to 100%, and after a few minutes after, check the battery usage and it should be not draining battery as it was.
It's a gb problem for some of us. In short, when charging hits 100% while the display still shows 100%, the charging actually turns off, but the phone still thinks it's on charge and cpu usage etc can be very very high. The worst I've had is unplugging it in the morning to have it drop to 30%, although around the 80 to 90% is the norm. It should only drop to between 97 to 99% on unplug. That's normal.
Until sammy fixes it it will be a flaw with 2.3.3 and 2.3.4 for some of us.
I'll add, I have a galaxy tab (got it a week ago) and it does not have this problem.
sirs, I recently flashed stocklite 7, and calibrated battery using the android battery calibration app (not with cwm rec).
Now, the battery shows empty and the phone turns off within like 25 hours, even with bare use ( won't last > 2 hrs with wifi / data on! ). I used to enjoy like 3 days w/o charging (with bare use - right).
When I plug it in to charge, THE IMAGE (charging while phone is off)SHOWS 75% OF THE BATTERY STILL FILLED, when I plug it in!!!
My doubt is, I believe there's some access problem or so, there is still 75 % battery left, and I need a way to access it. Is their any way to repair it?
THANK YOU.
I seriously don't understand why people ask questions in a thread and then make a COMPLETELY NEW thread for the same thing...

have you tried calibrating your battery? if you haven't try this.. i always do this when my battery gets miscalibrated. 1st turn off your phone, take out the battery and leave it for 1 to 2 minutes, put the battery back, go to recovery mode and to CWM recovery go to advanced and wipe battery stats, reboot your phone
give feedback if it works or not,,
This doesnt calibrate the battery,it only delete the logfile of the battery.i think he need a new one.please op,next time ask in right section.
MANY GREEEEEETZ!!!
Use only 2G Networks
1. Proper way to calibrate battery:
Drain the battery completely (use an Xposed module called disable critical battery shutdown, google it). Then, recharge the battery to 100% (DON'T unplug the charger cable while charging) and done.
2. Underclock when necessary.
3. Don't run too many apps at one time.
4. Make sure that deepsleep is working.

1. You can use Wakelock Detector from Play Store.
2. It is normal behavior...... if the battery status won't move from 99% to 100% after 1-2 hours (while charging), there might be a problem.

Hello
I'm new here and a basic user
A couple days ago I bought a used Mate S and was happy with it. I thad some screen burn-in (expected) and nothing else was wrong with it... until it reached 19% battery.
As soon as it happens, the phone sends the low battery alert and the phone shuts off (not instantly, it shows the "Shutting off..." message for a couple of secs)
I've calibrated the battery (I think I did it wrong may be?) but it just seems weird that it shows off as soon as the alert shows up.
I don't know how to fix this, but is it stupid to think that it could be fixed if I (somehow) change when the low battery alert shows up?
How can I do this? Or is there another way to solve my problem?
I managed to root the phone. Help please...
I had the same problem. I had change the battery and works fine

Ohh
But... is there a way to change the n% low battery warning? (set at <20%) I'm convinced that'd help xd
I saw a mod that gives you the option on the P9 forum, but it's for android N
