So my phone died earlier and I charged it up to 100%. Note that I was also running ICS4Bionic (latest build). So I switched back to stock by toggling Safe Mode and it tells me that my battery charge is at 40%.. (???)
I rebooted just to make sure and the battery level IS ACTUALLY AT 40%. Weirdest thing I've ever seen. Do I need to do something with battery stats or what? It doesn't even make sense.

I get excessive battery drain when I go back to nonsafe mode. Any suggestions?

Thanks, it worked.
Would an app like Battery Calibration work as well? Just wanted to know for future reference.

I essentially had the same problem. 100% to 40% when switching back to nonsafe.
It's probably not actually draining. Maybe you just need to reset the battery stats like it was suggested. It did work for me.
Yup same thing as fare as I know

Mine is a different problem. I know what your talking about because that happened to me also. I'm talking about my battery level draining really fast while in using it. I've reset the battery stats already and recollaberated it. My cell standby is really draining the battery very fast.

Get a free battery calibrate app from market. Wiping battery stats do no really do anything reported by Google.

So I am just curious. Why would I need to reset battery stats? Whats a good battery life? I know where to go to reset, but I don't see why I would need to. Any thoughts on this?
If you start getting bad battery life or a full wype rom can goof bat stats up sometimes. If you getting bad battery life for more then 5 days then you should do it. Becuase rom flashing and cause battery to go out of wack for a couple of charges. Also charger 100% with phone off, then wipe, then 100% while off... you also might want to search a littler bit better not to be rude but this link was 5 thread down in general...

There's not a single thread out there that has helped me with my damn battery life that I've been able to find. I'm sick of hearing, "did you search first?" Yes, I searched first. I didn't find anything that helped, that's why I made a new thread.
Anyways, I've tried apps, widgets, calibrating, deleting batterystats.bin, flashing different roms, kernels, modems, and even a new battery. Not a single thing has made my phone last through the day, and it's getting to the point where I'm about to flash back to stock, and forget about it. I need to be able to use it when I need it, not put it back in my pocket because I'm afraid of draining the battery. Honestly I'm not sure if the battery issue is rom related, so If that doesn't work, I may just get a different phone. I need to not have to charge my phone every 6 hours. Does anyone have any idea how to improve battery life on this freakin' thing? 6-7 hours on light usage is not enough. To put it in to perspective, I get 10-15% battery drain in STANDBY per hour. Serendipity 6.4 was a little better than 7, but not much. still within that 6-7 hour range. Is there anything else I can try? Anything at all? I went from 7 back to 6.4 because I thought Android System was draining my battery, but it didn't really do anything. I'm open to everything at this point. Voodoo, cult magic, anything.
Edit: reading through my message, I wanted to clarify that I am very grateful for your help, I hope I didn't imply otherwise.

I don't know what that is heh
Have you tried Juicedefender? It's helped me immensely. Other than that, I could suggest getting an extended battery, if you're willing to cope with a lumpy cappy. I'm too noob to know how to fix this problem other than by using the brute force route, but it's worth a shot.

Well, battery usage shows just about nothing... I was using 6.4 but after it did nothing for my battery life, I went back to 7. Now the android system thing is back but I'm getting the same battery life.
Here's what it shows under battery usage for today:
Display 29%
Android System 25%
Android OS 10%
Google Services 7%
Cell Standby 6%
Fancy Widget 4%
Handcent SMS 3%
Battery Graph 2%
Phone Idle 2%
JuiceDefender 2%
Dialer 1%
and that's it.
if you start seeing android system and android os that high, shut down, yank battery and let it sit for a few minutes. then replace and start up. should help with that and improve battery life.

The problem is, I'd be doing that every 15 minutes. It boots up already taking up more than 10%. I just did exactly what you said, and it booted at 23% for system and 3% for os.

flashed cyanogenmod 7, and turned off mobile data and wifi and just left it on idle for like 2 hours after resetting the batterystats.bin and rebooting... i uninstalled juicedefender because it was actually USING batter... *shrug* and left it that way... well, I opened battery left and looked at it and saw that it would die at like 5am... well, i was disappointed... until I noticed it was 5am, 26 hours from now. That's notibly longer than any battery left stat I've seen since I started noting battery issues... So... Yeah. I think I'll stick with CM7 for a while hehe. After I get an idle benchmark, I'll start using it more. Thank you for your help.
do you live in a poor 3g area?
the problem could be that the phone is constantly looking for a good connection and cant find one, causing massive battery drain

I was just going to say the same thing. If your phone is constantly trying to establish a connection, is alway searching, it's using up lots of juice. Same if you've got gps enable or wifi on. If it's looking, it's active and battery's being used.
Another thing you can try which helped me is to call art and get another free battery if your phone is still under warranty. The new battery I have seems to last almost twice as long as my old one. Of course make sure that the android os isn't eating the battery and mine last a while. Just a suggestion.

I was messing with my phone (rooting, testing out roms, etc.) and I decided I just wanted plain old stock. So I put it back to stock (official 2.3.5 gingerbread) and rooted it. Then I decided to calibrate the battery by using the Battery Calibration app in the Play Store.
Now my battery drains about 15% every hours in standby mode. Do I need to wait more time for the Battery calibration to take effect?
The calibration doesn't work on stock it only work on custom ROMs... kies calibrates the phone and reset the batterystats.bin so there should be something else killing your battery especially 3g...disable what ever you are not using rotation/data sync/bt/ ect.

"Calibrating" the battery is huge myth. It does absolutely nothing.
batterystats.bin is used to display what has been using your battery in about phone/battery use. That's it. Has nothing to do with calculating the remaining battery, or does not improve or decrease battery life in any way.
Furthermore it is reset EVERY TIME YOU CHARGE TO 100%

That's what I've read but it must do something, because since I ran that app and 'recalibrated' the battery, the battery dies in about 7 hours on stand-by. It would last me all day before I ran that app.
I did find one thing that was using battery on standby...my Beautiful Widgets Live Wallpaper. I set the wallpaper turned off the screen and after three hours I checked the battery use. I found that 'Display' was using the most at 50%. And during that time, it drained about 45%. I'll keep testing.
Oh yeah forgot live wall paper kill around 20% never use it so case close....
Sent from my SGH-I897 using XDA
It looks like that's the culprit. I must've put on the live wallpaper sometime after 'recalibrating' and didn't remember. I'll let you know if I have anymore problems.

Hi guys i have a galaxy s phone and it's working really great, but now a days it shows me some weird battery problems...
ProblemNo:1.Some times my battery shows like 45% or like that and it goes up to 46 or 47% after a few minutes during discharge
2.Some times when i have about 55% then if i remove my battery and put it back and when i reboot it shows only 5%, this problem is very rare but it's occurred more than 2 times
3. when i am charging my phone it's reach up to 99% then it drop down to 98% then 99,100
These are my problems,i am using MIUI 2.4.20 ROM
what causing these problems is it my battery faulty or do i have a hardware problem
or is it the ROM
please any one help me.....
Have you tried wiping the battery stats in cwm?
Or, trying a battery calibration app from the play store? For example, Battery Calibration.
Problem number 1 occurred to me a few times it isn't a serious issue.
Problem 3 you need to wipe battery stats and calibrate your battery (play store has apps for that)
Sent from my GT-I9000
My guess is that using multiple batteries is playing havoc with your battery stats, but what the solution is I have no idea to be honest

I fond that if its at say 50% and I reboot and it drops to say 5% it takes ages to discharge that 5% so I guess it has the same charge just reading it wrong, if I leave it for a while without using it it will go back up

i have 5 batteries haha i dont need to worry about my battery i dont care
My battery life is pretty terrible. Running stock, power saver, and Snapdragon battery guru. I have to charge the phone 2-3 times a day. I use in moderately to light through the day. At night, it will drain almost completely while I'm asleep. I had a Nexus 4 before and battery life was way better than this, same location, same apps, etc. I don't feel like I should need to turn data and wi-fi off to get more than 6 hours of virtually idle phone life from this device. Is this typical?
I find the phone is hot a lot too, when I am not even using it.
Please try to find out what causes this drain with the following app and post results after 1 unloading cycle

I downloaded it. Shut phone off and letting it charge, then going to see how fast it drains. To boot, its been on the charger for 2 hours and it has gone from 9% to 62%. Something must be wrong.
With stock my phone battery life sucked as well.that's why I rooted it and running a sense 5 Rom.. and it's so smooth I have my kernel UC to less than one gig speed and it still move fast without the overheat

Definitely not typical...
I'm fully stock and not rooted. If I dont touch my phone it can last over 24 hours with data on (noticed this one weekend when I was too busy to play with the phone).
I use the Battery Widget Reborn app and it says a "Fully charged battery usually lasts: 18 hours 8 minutes" for me.
Sounds like theres definitely some kind of app in the background thats draining your battery and making your phone hot.
This is pretty typical battery life for me with data always switched on on a rooted stock 4.2.2 rom and was also pretty much identical on an unrooted stock 4.1.2 rom.
The main thing that saves me a ton of battery life is disabling apps that I don't use. By far and away the Facebook app is a massive culprit for killing battery life.
I'm very interested to see the gsam results when you post them.

I did this procedure that HTC instructed me to do to reset the battery/charging system. I think it may have worked. No excessive heat and a drastic improvement in battery life. I've attached a screen shot of the gsam though. Just curious what you thought of the results

You are getting decent battery life. What most here would call bad. That looks like my phone, though. So, you're average.

Well it's a definite improvement over the sort of battery life you were describing before. There are always ways of improving battery life but as has been said many times before it's all a case of where and how you use your phone that will be the main factor.
