[Q] Battery drain - Galaxy Tab Q&A, Help & Troubleshooting

Hi guys,
I'm running overcome 3.01 Jupiter and my battery just drains overnight. I have also turned backlight notification off but it still drains. For example yesterday it aas on 67% and today it's on 27%. Does anyone else face this problem and how can it be solved? Thanks for the answers.

Try this : charge the battery fully, after that unplug the tab and reboot. It solves the problem on a galaxy s with gingerbread. I guess it's the same bug. It's not overcome related but gingerbread 2.3.3. Hope it helps.

Can you tell me what is using the battery by going to settings>about>battery use?

[Question]Display drains Battery after flashing XXJPK for days

Hi experts here,
I am new i9000 user coming from G2.
I flashed XXJPK for days, found that my battery drops very fast.
I stop all data access at night and the battery still drops...
I found that the 'Display' uses > 80% !! (even when I slept for 8 hours)
Attached is the screen cap of my battery stats..
Do anyone has the same issue?
This is Android Development, not Questions & Answers! Please post in the right sections!
What have you installed after JPK? Task killer? Lag fix?
Mine is not doing that. I did a hard-reset yesterday, installed my apps (no task killer, no root, no lag fix) and disabled everything (WiFi, bluetooth, GPS, 3G, autosync). Battery did not drop even 1% in 6 hours.
Display should not take any battery if it's off. Maybe you have something that awakes the phone constantly. Check autorefresh on weather, e-mail, twitter, news feeds... I usally have that disabled or set to 8 hours minimum.
got the same problem here.. i do got the docrom (custom rom) ,auto killer installed and lagfix (OCLF v2+) it goes from 100% to about 60% in 9 houres.. without doing a thing.. on top of that i got juicedefender ultimate installed.. but it doesnt seem to help at all..
The problem is why the 'Display' uses > 80% while I off the screen for hours?
Got the same problem here. I just reverted back to jm8 (eclair 2.1) with takayuma Rom.. I think all froyo versions have battery draining issue
I think, you guys must make this and maybe fix battery issue:
Refreshing battery stats after Odin or flashing (important)
or me personal, for my Galaxy very helpfull was this HTC Desire methode:

I'm having exactly same problem with you. My brightness is 75% even in sleep mode and it drains the battery. I guess thats the main culprit to solve my battery draining issue. I wonder why it happens to certain people, because some users only have 48% for brightness and their battery can last more than a day
** apparently using Eclair 2.1 doesn't solve the issue as my brightness is still 70% ... I've tried the batterystats.bin fix and same thing happens. Damn !

It's true. JM8 and the battery fix doesn't help.
But I found that when I turn my connection from 3G mode to Wifi mode, my battery drops only 10% overnight.
I think there is some problem in the 3G connection.
Do you think this is kernel related?
One way to keep the drain down is getting a black theme such as the Transparent theme and setting a black background. Because of the AMOLED screen black is basically 'pixel off'. It helps just a bit.
I have similar experiences with WiFi vs. 3G, 3G drains battery awfully fast whereas WiFi seems to be consuming significantly less power.

My weird battery

hey guys.. I need your help here.. My galaxy s can only last with display on for around 2 hours.. Is it normal? Oh I'm running Darky's Rom v9.2.. Need your help guys.. Thank you very much..
I don't think 2 hours is normal no
So that means you have something draining your battery fast, some app or anything you just installed?
Also check out this topic:
http://forum.xda-developers.com/showthread.php?t=884816
There are many problems posted resolving to batt drainage so look around on the forum since we don't know what apps or other stuff you do with your phone but it sure ain't normal.
Did you flash Darky's ROM with 100% battery? Maybe try charging it fully when your phone is off, then wipe batt stats, drain your phone and charge again.
If you did not have the problem before then its the rom you flashed or a bad flash .

[Q]Battery problem?

Hello all,
I am now on Nova 8, after trying Cm7, then stock, then nova 8. The problem im facing is that I think the battery life is shorter than it should be. I used battery calibration app and when its close to 0% still shows 3000+mv, is this correct? Or it should be close to 0. After using this App the problem persist. Im not sure if its my imagination or the battery should last longer but with a light useage the phone hardly reaches a day.
Thank you in advance

First, this is the Development Section and not for asking questions. This should be posted in General Section. (Reported and now moved)
Whenever you flash a new ROM or exchanging one for another, you should always wipe battery stats (CWM). You can however do this now directly without that app. Charge it 100%, then reboot to recovey (CWM) then wipe battery stats.
To answer your question. You might have mistaken a battery drain would equal to 0mV. Batteries like ours has 4200+mV at full charge, and a discharged rate of about 3000+/-mV. This could be well explained by someone like huexxx.. XD CMIIW

Battery drain while Phone is OFF!

I just bought a used galaxy S, I think something's wrong with this phone, I am having horrible battery life, 100% battery drains in a few hours, on standby! ..battery is even draining while phone is off... I had over 75% battery at night, I turned off my phone, and slept... woke up to find 0% battery..
Anyone else experienced this ?? Any suggestion how to fix?? I had stock 2.3.3 rom, then I flashed stock 2.3.6, now I am using GamerzRom.. I had same issue on all three roms..is it hardware problem?
from my experient , 2.3.3 have a big probleme with battery drain , try 2.3.4 JVR STOCK or 2.3.6 jvz stock , but without root , or flashing a roms(GAMEROMS, on its rom , the processor are overclock at 1.2 gbz , and battery is discharging more faster) ,and after put 2.3.4 or 2.3.6 , make a factory reset and wipe cache

So the battery is draining with the phone off..... Is it draining if you remove it from the phone? Charge to full, remove for a few hours and then check.
Then check accessories section for advice on a replacement battery.

Last night I left the phone off, after removing the battery, it didn't drain at all, but obviously it wasn't in the phone.
And I had a different battery before, this is the other battery I got from the shopkeeper as replacement, its original battery of galaxy S but not new, more than a year old...
I am wondering if my battery is faulty or phone?
Have you checked the battery pins?

Two pins are normal, one pin is a bit pressed..somewhat
I think your battery is dead. There is no way a Galaxy S with Stock ROM drains 75% over 8-10 hours of standby.
Was 3G on when you went to bed, bluetooth, GPS Etc? If so, THEN I'm not supprised.

I agree. Change the battery then try again
I did try another battery, both batteries were in good condition, probably Galaxy S had some problem, I returned it to shop...

[Q] Samsung Galaxy Ace S5380 battery issue

My ace's battery is not even lasting half day even with no major use. (Just some calls). Using code *#*#4636#*#* mentioned in one of the post here i checked for my battery health. The health is good but the battery voltage is shown as 3.0V . I suppose it is 5.0V for Ace.
Is my battery faulty ? or there is some other problem? Also please suggest any way to find the correct battery health.
I am currently using official Gingerbread 2.3.6. Thanks in advance
I had even weirder situation, when my battery would drain minutes after charging.
I tried every battery calibration, saver whatnot but it didn't help.
So i wen't and bought a new one, and voila, my problems were solved
It seems that batteries don't last that long as they used to...
