The display seems to consistently use too much power.
After six hours unplugged today:
The battery usage screen shows
Display - 98%
Cell Standby - 2%
That's kind of ridiculous since the battery history menu shows the screen having been on for only 1hr 43 minutes
As said in the title the remaining battery is currently 34% after 6 hours in from 100%
Any advice? I've had terrible luck with the SGS's so far (1 soft key sticking, 1 fried internal SD card). None of them were spectacular on battery life but this is by far the worst unit.
Battery drain you must have loads of stuff turned on .

Do you have android 2.2?
it shows all the not standby usage as display usage. a bug in 2.2 i think.
So the usage you see is display + the programs you are using.
Yeah it is 2.2, I didn't realize the usage stats were bugged. As for loads of programs, I don't run that many but I've only been using the Level 2 Clear Memory function in the RAM manager to end programs. Too much debate around task killers for me.
OS Monitor shows only a few non-stock programs running right now, are any of them battery drains?:

Try this it worked for mine
1. Use your phone until the phone switches itself off (battery empty)
2. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
3. Now, keep switched off (!), plug in charger & leave in charging until 100%
4. When battery is full, switch the phone on, unplug & check if the batter immediately drops 1 or 2 %
5. If battery immediately drops, plug in charger once more (while running phone) & let it charge completely
6. Once charging to 100% is done, keep charger plugged in & Reboot into Recovery Mode
7. in Recovery Mode go to: advanced --> Wipe Battery Stats --> Yes-Wipe Battery Stats
8. When done: Go To --> reboot system now
9. Once system has rebooted, unplug charger
************************************************** *********
After 3-4 full charge/full drain -cycles, do the following:
1. Charge the battery up to fullest.
2. Keep it plugged in to charger, and reboot to recovery.
3. On the recovery, go advanced, wipe battery stats, scroll on to yes BUT Don't wipe them yet. When you're ready, quickly remove the battery cable and push to wipe the battery stats.
4. Reboot the phone, use normally. Let it run completely out of battery.
5. Charge the phone back to full. Turn off phone. Charge until it says 100% on the green bar and vibrates for full charge.
6. The Important Part. Remove the charge cable for 0-0.5 seconds and plug it back in instantly. Let it charge to 100% again. Do this 1-2 times again, so you've done this 2-3 times total.
7. Reboot to recovery, wipe the battery stats again as on the step 3.
8. After wiping the battery stats, plug the charger back in the phone.
9. Reboot to ROM. Keep the cable plugged in. Keep it plugged in for about 30 mins to 2 hrs. Unplug. Should say 100%, mine did for about 40 mins after it depleted onto 99%. And this is the way you should really gain great battery performance.
************************************************** *********
First 2 times I drained it heavily, WiFi on, 2, 3 music players on etc. (charge up while phone isn't started).. The last 3 times whith a normal usage..
and charging while phone is running.. every time it says it was 100% and when I got the full-battery-notification, reboot into recovery.. clear battery stats..
************************************************** *********
1) Turn OFF phone
2) Charge till it says it is FULL
3) Start in RECOVERY (volume UP+Home+Power), here WIPE battery stats (it is in the "advanced" menu)
4) RESTART android (yes, it might already be on 98% or so)
5) USE phone heavily. Don't worry if it drops too fast. Use it till the Android system turns OFF automatically (it happens when your battery is below 1% - for me the phone was on 1% for about 40 mins. This is where it heavily miscalculated
6) PLUG IN your charger, TURN ON android and wait till it is FULLY charged again. (It is better if you don't use the phone at this charging up)
To follow all those instructions would literally take 2 weeks. No phone is worth that much effort.
It's not that bad just try the first option if that don't work, move on two the next one, really not two much hard work: )

Yeah I meant an abnormal drain on the magnitude of 70% with 1.5 hours of use and 4.5 hours of basically idle
just try this option
1. Use your phone until the phone switches itself off (battery empty)
2. Switch on once more to make sure battery really is 0% (it will then immediately switch off once more)
3. Now, keep switched off (!), plug in charger & leave in charging until 100%
4. When battery is full, switch the phone on, unplug & check if the batter immediately drops 1 or 2 %
5. If battery immediately drops, plug in charger once more (while running phone) & let it charge completely
6. Once charging to 100% is done, keep charger plugged in & Reboot into Recovery Mode
7. in Recovery Mode go to: advanced --> Wipe Battery Stats --> Yes-Wipe Battery Stats
8. When done: Go To --> reboot system now
9. Once system has rebooted, unplug charger
what apps have u got running,things like gps wifi turned on all time will drain battery life.

I can't find the "Advanced" menu in the Recovery Mode, is it there stock?
have you got ( clockwork recovery v2.5.1.3 ) installed you need this two use the option i give in the thread,if not try and install rom manager,i think rom manager installs cwm not sure ?
ps, has the phone been rooted,and is it stock rom or custom rom.
Epic Fail...
I've never felt comfortable with rooting or custom ROMs so I don't have any of that.
Also I just tried the 1st batch of instructions, except without the ability to erase battery stats I did a Factory Reset instead... the results: (I kid you not) 100-0% in 3 hours.
The screen's been on for 1hr 30min, with the phone awake for only 10min more than that
I'm really hoping the phone's just super inaccurate right now, and "critical battery" actually lasts several more hours... although I'm not sure how any phone could be that inaccurate.
I realize that calibration isn't supposed to make it worse, but this time it actually made it about twice as bad
Definitely just died...
when charged does it read 99% or 98% when u unplug the charger
When i use my phone with internet and downloading i get about 8 hour's of use,when on standbye,it will last for about 3 days, it all depends on what u use it for how many app are running,but for me just installed darky's rom 9.2 now get longer battery life, but still the battery life on sgs is really bad compaired two my last phone that would last for 7 days without charge.i would flash darky's rom would someone else flash your phone for u,or read up on flashing on xda they are loads threads about flashing custom roms
mark204
if you are thinking of flashing a custom rom make sure you have the three button combo working vol up home key and power buttons two enter recovery mode and vol down home and power for download mode,you need two have this before considering flashing any custom rom
Hi!
I cannot get this option to appear in 3 Button Recovery Mode.
This option: "rm / data / system / batterystats.bin" serves to activate the wipe option in Recovery Mode or wipe it directly?
tks!!!

Ofcourse, your SGS must be rooted....

I hear that to calibrate the battery, we need to make full charge/discharge several times. So when did we have to wipe battery stats? And why did we need to do it?
If wipe battery stats will reset the battery state to 100%, so it will be enough to charge the battery during the night to be sure it's full then do a wipe battery stat to make it calibrate with the real battery current state (full charge = 100%). Am I right?
I donot understand how the battery stat work? please help!
Thanks
In my experience wiping the battery stats is not necessary, the meter will calibrate itself with every cycle. If you want to speed up the process and be nice to your battery let it drop to 5-20% before recharging.
With some FW even a batterystat wipe won't help.
I have bad battery behaviour with JPY, also my wife which has even less apps who are active online, like K9-mail.
Hope with XXJQ3 the battery will last longer

NC battery can be charged, the indicator will turn green, the use of normal, NC battery has been displayed 11%,How to make the battery indicator to 100%？
Reset battery stats
Try rebooting into recovery and under advanced reset battery stats.

i also have this issue, but stuck at 31%. nothing works... tried clearing nc batt stats, manually deleting the batt stat file, and the app which doesn't work since its waiting for batt to hit 100% and forcing it does nothing too.

I had this same issue. I tried every app suggestion I could find online and even cleared the battery stats in recovery, but had no luck.
Eventually I think I had an OTA update break my root so I had an excuse to do a system wipe/update (from 1.2 to 1.3 I think it was) and while I was in clockwork mod recovery I did a complete system wipe (format everything, restored to 1.0.0) and reset the battery stats. When I finished the manual update to 1.3 and rooted, the problem had gone away.
I'm currently running eyeballer's CM9 nightly and have had no further problems with the battery indicator.
Hi. Today I noticed strange thing. When I charge my phone to 100% it shows 100% from 4.24V to 4V and only under 4V it jumps down to 99% and then it's going down. I compared it with TWRP and there is 10% difference between system indicator and TWRP. I wiped battery stats, cache and dalvik. Battery is dying or something else? I just finished installing all after wipe and I'd like to avoid another one.

That's charging optimization enabled, battery will never get fully charged instead it will charge a lower % and show you it's 100% charged. If you want to disable it it's somewhere in Settings > About > Status
Ha, thats it!!! I felt that something is wrong with battery just after update but I thought that 1.5 year battery can be a little used. I didn't know about this "future". Thank You.
