Is there a fix to the battery bug where ROMs flashed in Safestrap would not report the correct % battery? Is this an issue with the Safestrap software or the ROM (I'm using CM10). Will flashing Minimoto GB fix that problem?

Yes.
Minimoto did not fix the problem for me imo its safestrap. If i want to make sure my battery is charged up all the way i have to charge it in my safe side
Sent from my DROID3 using XDA
I haven't had this problem since switching to minimoto. I think it's an issue with the kernel & safestrap 3.05.
The only bug I see is that within safestrap the battery % is still buggy
Well safestrap 3.10 should be out soon, so it might be fixed in that update

So over the last couple of months I've been burning through 2 batteries (or a recharge) a day...could this be caused by SafeStrap itself? I've got SS 3.05 and I'm just running the stock rom but battery life has been terrible. I've been looking at all my apps to find a culprit but now I'm wondering if it's SS itself.
Have you tried charging overnight and calibrating the battery?
Sent from my DROID3 using xda app-developers app
Safestrap only affects battery while it's booted into SS. What apps do you have installed?

Yes I have, multiple times. I've stripped out apps that seemed to be battery hogs but to no avail. Next step would be to remove safestrap and/or factory reset and completely start fresh. Was hoping that this was a known SS problem.

So while running the stock rom SS should have no effect?
As for apps the worst offender I have is Tunein radio. I know that app eats battery but I'm having problems even when I don't use it. Beyond that I'm just running normal apps. Facebook, Google+, Dolphin browser, Tweetdeck, K9 Mail...those are my daily use apps. I have others installed of course but rarely use them.
If you have facebook, google+, tweetdeck and k9 all automatically syncing all the time that would put a heavy draw on your battery. Your battery which is probably getting pretty old at this point and will have lost some capacity. Also if you live in an area with poor cell signal and your phone is constantly searching for a better signal that will run you down in no time.
What do your battery usage graphs look like at the end of a normal day/charge? Which processes are the largest consumers? What does the phone signal line look like? If there is a lot of red and dark yellow there then that's probably the culprit.
I would suggest checking the battery. Take it out and physically inspect it, look to see if it's bulging in the middle. You can also try spinning it on a table, the more its bulging to better it will spin.

DUDE! Amazing call, I would never have thought of that. I have two batteries, one spins like a top and the other barely moves! The spin test was the kicker, to look at the battery I can't see any bulge. Funny thing is the bad battery is the newer of the two. Guess I'll be buying a new battery and giving that a shot.

Ya they have a limited number of charge cycles. A friend of mine has the same phone, but does lots of video streaming, she was having to charge it all the time and she ended up with the same problem. And it was a totally stock device

So I borrowed the extended battery (vzw bf6) that my son had in his old D3 and suddenly my phone is working as it should. It would appear that my problem was 1) an old and tired original battery and 2) a second replacement battery (vzw, not aftermarket) that was defective. Have never had a problem with a replacement battery before so it never occurred to me.

It's certainly worth a shot. I had the same thing happen to me once a while ago and it seriously extended my battery. There's some threads here that describe the process which essentially involves discharging and charging your phone off and on and deleting the battery stats through CWM.
I always flash a ROM with a battery showing 100% and I typically net pretty good battery life doing it this way.

You can calibrate at any time. No need to reflash.
Maybe before you reflash, please wipe of the factory settings and partition and also the Dalvik cache and battery stats in "Advanced" settings using your Clockwork.
Ok I'm trying one of those recalibrating methods. Maybe I really should've read everything before I flashed... but there was sooooooo many stuff to read and watch...
When you say "advanced" in clockwork, thats the rom manager correct? when i look through it it says advanced mode for premium users only... is that the right app?

It gets recreated, yes.
Have to remember as well that each user may see different results with the same Rom. Kernels. Modems, Roms perform differently from one device to another based on a multitude of factors. After you have done the basic steps to try to stabilize battery drain, I would then begin by experimenting with different kernels and modems.
Idle drain is the test I normally use after ensuring proper battery readings, sensor usage and app CPU behavior. Many times simply flashing to another kernel shows immediate results.
Sent from my ADR6300 using XDA App
I've yet to learn about flashing kernels. I'm now running perception 10.2
Sent from my SGH-I897 using XDA App
Download the sgs kernel flasher app from market. Go to kernel thread off your choice in captivate development an download kernel, placing the file on your internal sd card. Run the app which is poetry self explanatory.
Definitely try a different kernal or modem. Generally, you can find feedback in the rom thread about what kernal or modem gives the best battery life.
I haven't used Assonance but I had to flash the firebird 2 kernal to get good battery life with Perception 10.2. Keep trying.

Seems to be a common problem, I experienced it myself on one of the leaks. The service restarted, found a problem and exited, got restarted etc. ad infinitum.
Agree, just root, and take a look at this post.
If you open dialer immeditely after the phone boots up, on screen phone starts to hog battery. So let the phone sit for a while, 10 minutes or so, and this doesn't happen. Same applies for camera, at least for me. Youtube app does the same regardless of when you open it, haven't found a solution for this one yet.
I had the same issue on V20L. So I removed OSP and the problem is solved.
i have some other doubts about this app and situation in general. if you see actual usage stats, that this app is not running at all (some sec of cpu time). what i noticed, after updating to v20l battery stats are total messed up. f i launch for exaple some other app jus after chargeing...thiss first app will always have 25-30% of battery usage in the end...even if i have used and than killed it seconds.
anyway, i will go for rooting and removin all those unnessesary aps.

Well I'm on cm7 and 1.1.5 (I've not noticed any difference between 1.1.4 and 1.1.5), and I get two days on a charge. I don't have facebook/e-mail or many other app syncing and I don't turn it off at night or anything like that.
I've seen people saying they get longer on a single charge but then you usually find out they're switching it off or putting it on airplane mode over night or something.

Stock ROM 4.0.4 and have never rooted or flashed anything on before. It is completely stock and unaltered in every way. All I've done is install apps. It just seems to have been a little bad recently. I have BetterBatteryStats on, but the it isn't wakelocks. As I said, I've got the screen on consistently so the phone will always be awake. It is just that 20% in that amount of time seems really high, even for constant use, and I swear it didn't use to be that bad. I've installed Juice Defender because it tends to be good in how it managers network and WiFi. So far, things seem to be stabilising. But, I still want to know what can cause such sharp drainage...
Do you have a lot of apps running in the background? This is most likely the cause. Brightness is a big issue also. Flash a kernal!

Check that you have Auto-brightness enabled. Also, I found that certain apps can drain battery big time. I agree with checking via a battery stats program. Maybe an APP is running in the background causing the cpu to stay at max speed?

Totally agree. Before I root my Note to delete some unuse apps from stock 4.0.4, the battery drains very fast. The most reason is some apps running in the background.
Did you change your sim recently? Sometimes the culprit is sim card.
Sent from my GT-N7000 using xda premium
Not fixes, but suggestions:
- An app like Green Power will stop data usage when screen off
- As others said, look into your display. My favourite app is Display Brightness as it adds an invisible slider on your screen
- For some reason, Chrome in the last week began to EAT my phone. I uninstalled it and I'm back to a blessed 1% an hour drain

You may have to check your battery. Will it be hot when you are using it? Look at your battery, does it look "fat"? It happened once to me before, after changing a new battery. It's fine now. It was caused by overcharging it during the night.

THIS BUG CAN DO HARM TO YOUR BATTERY! BECAUSE YOU WILL NEVER KNOW WHEN THE BATTERY DRAINS!
As we all may encounter the battery bug after upgrading to .423 fw. When one restarts his phone, he has chances that the battery level of the phone rises (e.g., I turned off mine just now at 26% and turned it on showing 51%). This has been confirmed by many users in the forum, so I believe it is a firmware level bug of 4.2.2.
Is there any one willing to pay some time on fixing it? Coz this is a quite crucial bug for us, we dont know when will our phones automatically turn off! Thanks in advance
I believe its not a caliboration thing coz we also upgrade or wipe our devices before, and no such thing happened. I think its a firmware or kernel level bug. Does anyone who flashes a custom kernel also encounter the same problem?
It seems that Spanish FW is free from this bug.
http://forum.xda-developers.com/showthread.php?p=43261281
plz report your rom or base FW in the reply. Thanks.
[NEW EDIT]
It seems that I fix the bug. The battery jumps when the phone restarts, so I think there is something during boot which causes the issue. I delete the XZDualRecovery, and test the phone several times, and its fine!
Deleting XZDualRecovery might be a temporary fix, so you can choose what to do
[NEW EDIT 2]
someone reports that they dont encounter the bug and believes that its the calibration thing. i declare again that i DID the calibration and the issue was still there. for me, at least, deleting XZDualRecovery fixes the bug. plz report more details in the reply, like fw, root or not, recoveries. Thank you

Now the battery life seems good. I checked this by using WiFi whole night....battery lasted overs 12hrs

Think I'm gonna try this to when I have the time. Phone just went off because the battery is dead, it was showing 14% and all of a sudden 0%.

This is exactly what I concern. I dont know when my phone is going to off, and it could be big trouble when there is no access to the charger.
Maybe we just need to recalibrate, drain battery to 0% and fully charge it to 100% while the phone is turned off.
plz give some feedback if it works

hello all me too experienced the same problem but I successfully regained my battery life. Here is what I have done....
1)First I drained the battery fully until mobile gets switched off
2)Then I left the mobile to cool off for half an hour
3)After that I charged the battery upto 100%
4)Following this I switched on the Mobile and did the battery calibration by using 'Battery Calibration' app
5)Again I fully drained the battery and charged it again to 100%
Now the battery life seems good. I checked this by using WiFi whole night....battery lasted overs 12hrs

I experiencing the same issue. 2% to 55% after reboot. wow... 4.2.2 doesn't bring anything for me to consider to keep it. so back to 4.1.2 (.4.3.4)
But one thing for sure (never discharge a lithium ion / polymer battery from full to 0 they don't like it) you could do that with nickel cadmium/ metal hydride batteries ant they really thank for that if you keep doing that you just kill your battery before its due time.
