Anyone else experience battery skipping percentages? Mine, for example, skips from 12% to 6% to 2% within about two minutes or less. I read wiping battery stats doesn't do anything but want to try anyway. However, there is no option to do so in twrp. Are there any other suggestions besides wiping battery stats?

Ok first, it seems when I shut my screen off and its not doing anything, the battery seems to just drain. I'll be using it for like 10 minutes and maybe lose 1 or 2 percent of charge, but then I turn the phone back on, it lost like 8 percent. I don't get it.
Second, whenever I completely shut off my phone, it usually looses around 10% of power. Just now, I reset it and lost 20% of the charge. I mean wtf?
If anyone could help me out here and explain this that'd be great.

Go to menu, settings, about phone, battery, and click on battery use...what does it say? Also, you might want to cycle your battery a couple times to maximize the performance.
If all else fails recalibrate your battery.

I installed a scanning app. When I realized this app was using 10% battery, I froze the app using TB. After freezing and re-booting, I still saw a 9% drain. It was not until I removed the app did it disappear from the battery usage page. Does the battery usage page show real time battery usage? Just trying to understand the 9% battery drain from a frozen app.
The 9% you saw might be what the app used before being frozen. The battery usage is reset when you charge your phone fully. After that, the app shouldn't show up in the battery usage.
I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.
Do you use any of the power management settings like stamina more or....
What apps do you have installed?

Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.
Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.
So you mean not use stamina at all or switch it off at around app. 50%?
Try without stamina mode.

Ok, I'll give feedback in few days. Thanks.

I've tried once without stamina but I got visible faster discharging so now after update to 4.2.2 I am testing with stamina ON.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

my opinion
Sorry, it will not improve your battery, just if you have wrong indicated battery %,it maybe solve that. I solved a problem like that.my battery went from 50% down to 18 in a cuple of min.after deleting the stats and a few charges it was O.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.
The G+ post I linked to was written by an Android framework engineer, so I think they know their stuff

Ok,maybe i'm wrong,but somehow my problem was solved
I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.
Hi guys,i installed this ROM yesterday to my GT-S5830
http://forum.xda-developers.com/showthread.php?t=2212438
Now i have a problem with battery, this morning I charged it to maximum, and after 5 hours after getting off the charger (and about 45 minutes of effective usage (reading news and using facebook over mobile data)) battery level is 13%...
When I go into Battery stats it says that Screen uses 100% of battery ,and it's Time on is 1h 1m 6s
Brightness is set to 50%.
What could be the problem?
I'd guess that you can't go into deep sleep mode and that some kind off app is waking up your device..

That came to my mind too. How can i find which app is waking it?
I have installed WakeLock Detector, and it showed that Facebook made 120 wakelocks over night, though Facebook is not even listed in Battery stats.
I have set refresh interval of facebook to 1 hour, chat is off, how do I solve this problem, my phone is almost unusable with battery like this?
guys please help me, i deleted facebook completely, but it's not problem, when I get phone off the charger and use it for few minutes, battery drops to 70%!! It should not be battery issue,as when I used it with stock ROM there until few days ago it was OK. I've done Wipe battery stats in CWM after ROM install.
Try a full wipe & flash your rom again.

Mine is at 9%.
how did you pull that off?!
first battery cycle with m, it was high, and my phone never slept. second battery cycle, and it only reached 1% battery drain, and I had 4+ hours sot at 61% battery. btw, I'm using the permissions option, and am not allowing location for any of my apps that dont need it. also, I disabled background data for google play services.
