Today I was out using my nav app and things seemed really laggy. Without thinking about it I held power button in until phone powered down, at the time I had about 60% and when phone came back on I had 11%? I powered down by way of the reboot menu 4 more time and every time I would get a little bit more until it just stopped at 39%. Has anyone else had this problem?
P.S phone seems to be ok after full charge.
Have you tried running the battery calibration app from the market place?

Battery calibration app does nothing to our phones. Ask entropy he's explained it before. Also I have had that as well, but it will come back slowly, but should still be charged again

Would this happened if I were on stock?

Hard to tell it could just be a power management fail

well I let it get down to about 5% then gave it a full charge, and its working great now. funny how a battery pull and many restarts would not fix the problem.
Battery calibration does nothing on our phones.

So my phone says it has 20%, plug it in and it immediately shows 60%. When it gets to 100%, as soon as I unplug, it shows 70%. Anyone else seen this?

How can you even make a post like this without even telling us what rom your using at the absolute least.

Sorry I mean wipe battery stats. You wouldn't wipe if not at full battery or what?

No. Your phone will think the spot you wiped is full charge.

Not exactly. I have wiped the battery stats when my battery was less than 10%, and it didn't go back to 100%. Regardless, it was for reasons other than getting an accurate reading.
Can you wipe the battery stats at anything other than 100%? Yes.
Is there a good reason for doing so? I can't think of one. The reason for wiping at 100% is because it's going to be a fairly accurate place marker for obtaining accurate battery charge.
I use battery calibration app from the market to wipe my battery stats after I fully charge my phone but when I change batteries it never shows full charge even though it is. Any suggestions?
I'm using PB 1.6 with T15 kernel

Wiping battery stats does nothing useful. More then likely the problem is from using generic batteries. I know when I switch to my Hyperion batteries. Try plugging in your phone or toggling airplane mode on and off.

Battery stats works for me when I switch roms... You don't want to wipe battery stats every time!
I don't know about you, but do you really need that extra 1~2% battery for a full 100%???
I have eb with faux kernel and usually I get it to 99 and in some cases 100%. Even at 100% I'm at 4175 mv or so when it should be at 4200mv.
Point is, your not going to miss that extra ~25mv out so of juice.
Check your voltage and let us know.

No what I'm saying is if I change my battery at 6% when I power back up it still says 6% at 4100 or so.

I only wipe battery stats after flashing a new rom.

WIPING BATTERY STATS DOES NOTHING USEFUL. The only thing it does is clears the settings app that tells you what's using battery. Why do people never listen...

Does that on every reboot doesn't it? No need to get hostile
Sent from my LG-P999 using xda premium
I'm not getting hostile I'm simply stating it does nothing useful. This has been confirmed by Google engineers as well. So wiping the battery stats will not change battery reading.

Did you try the two methods I mentioned in my first post?

Hi. I have recently flashed cm9 on my galaxy s 4g,and it's amazing. My only major issue Is that the battery drains from 100% to 0 in less than 4 hours with lite use. Is there something I'm forgetting to do or is it a typical issue? Thank you

Battery calibration.

I've already tried that. I'm still having the same issues.
Sent from my SGH-T959V using xda premium
Unfortunately, it could be a number of known "usual suspects", such as apps or possibly a 'rogue' app, signal strength (the more the phone has to seek connection, the more battery drain), try swapping your SIM, settings to help maintain acceptable battery discharge, wifi, Bluetooth, GPS, sync, are just a few things that could be the cause. You can try a full charge to full discharge until the phone powers down, then while off, charge fully and power back on to clear battery stats. Could be your battery as well...

Use better battery stats to see what is killing your battery

It says audio out 1
Sent from my SGH-T959V using xda premium
Check the cpu scaling governor. Usually 'ondemand' will do a decent job of conserving battery power.
Also you can use the 'top' command from the terminal emulator to check for processes hogging the cpu.
Moved to Galaxy S 4G Q&A section. :good:
Battery calibration is a debunked myth.
AudioOut_1 suggests keypad clicks, or some other alert sound. Try reading the BBS thread for suggestions, posting your logs there if you're still puzzled.

i advice you try Gremlin Remover Step 1 and 2 (FIRST!) then if problem persists more on to step 3
EDIT : Gremlin Remover can be found on the development area or here you go: http://forum.xda-developers.com/showthread.php?t=1500427

The battery might be dying. You should try another one because I noticed my stock battery started to stop lasting as long as it used to

I noticed a significant difference between the battery life of CM7 and CM9. 7 is really good with battery life. 9, however, shows the SCREEN as being the main drain of the battery...even if it's been on my desk all day.
