Well, depends on phone configuration and what you installed.

How about screenshots without the volume indicator? You can also try GSam Battery Monitor from the Play Store, to get a little more information on what is eating the battery.

Did you install any app after or before update? Main reason for all drain is from app.

What's your screen on time.
Looked kinda like liteflow might be causing problems?
Cell Standby i think is the one that is coded wrong and is lying, ignore that one.
If you press Android System in settings, battery it will show you the top components being used
Also in dev options look for and check Show CPU Usage. It will show whats using the cpu in the top right of your screen. Watch for what stays in the top few spots in the list.
There may have been something that didnt like the update. Try first uninstalling apps and if that helps reinstall them clean, no data restore. If you continue to have problems backup all data and factory reset. Start clean.
If all else fails use odin to flash the full LH2 fw.
LH2 should be a fairly stable build. Most have no issues and many get outstanding battery life. Im willing to bet its either an app or the way you updated or both.

That's really not THAT bad for a screen on time. I saw your screenshots in the OP, and you were down to 80% in only two hours of being on the battery, but you had the screen on for almost an hour of those two hours; 20%/hr for the first few hours is pretty normal. It's not stellar, but I wouldn't say it's an epic drain that being said, I'm sure you could squeeze some more juice out of it, and prob is just an app causing more drain than usual.
Also when doing a screenshot, it helps to hit the power button first, then the volume, so you don't get the volume pop up every time.

3:30 screen on time it's good no matter how you use your phone. I got 2.45 hours on screen with 1day and 6 hours. I've had issues with liteflow and battery as well. Others say they don't, it seems to depend on how you set the phone and liteflow to work.

Why is my battery showing this?

My phone was working fine, but now this is my battery usage. I have restarted twice and it still shows like this.
Plus my CPU has been running for 248 days or something.
(Guess my pics didn't upload)
The battery is showing android os as 100% off my battery usage.

Alright, I'm a noob, I was with you up to reboot your device. "Go to recover and delete battery stats" was where you lost me. Maybe some more detail or a hint on where I can look to learn about it would be super helpful. Thanks.

Are you rooted at all? Installed any custom recovery? i.e. CWM or TWRP. You need to have installed a custom recovery to delete battery stats.
As for the android OS usage, that's very weird. Try searching it up on google and see if any results pop up. You could delete battery stats but not sure if that'll help. If you'd like to know how though, let me know.
If u r rooted and dnt have a recovery, download a app called 'sdmaid' frm store, and u wil get an option of delete bat stats!
Sent from my WT19i using xda premium
Not rooted, yet, but plan to add I learn more. Well full charge tonight and see if it clears. If not, will search for similar issues as you suggested. Thanks.

I had that happen to me when I first bought the phone. Was terrified I would have to return it. Just charge it to 100% and reset it. No reason to put it in recovery or anything. That fixed it for me.

[Q] Battery life? WTF? 10% an hour doing NOTHING ?

I lose 10% an hour (sometimes more) doing absolutely nothing with my phone. I check battery stats and like 98% is screen.
Question: how can that be possible if the screen isn't even on ?
I have tried everything. I'm running CM10 stable (which is supposed to be good for battery life)
10% an hour? This is a joke right? I have like no apps running. I even tried using apps that put the phone into DEEPSLEEP as soon as the phone/screen shuts off -- meaning every app is closed.
Nothing.
Any ideas? please help i love this phone but im going through 2 batteries a day and im not even using the phone that much.

Xperia Ion L28AT Battery Malfunction?

Ok so I used this guide here to update my Ion L28AT and when I did it it started going from dead to after a minute of charging to having a full battery. I said ok it must be buggy so I restored to a stock w/ root version and the problem persists. Didnt happen before I started this whole mess. Maybe I left something behind on the prior install?
And is there a guide for a 100% reset and install? Like wipe then entire fire and all sdcards...
I just restored with Sony Software and reinstalled backup/restore apks from ganeshbiyer at this link
Then I installed battery cailbrator from the play store. So far it is looking good. Will keep you guys informed.
And nope did the same thing.
2 days and no one has any ideas?

Well i mailed it back to Sony for repair. 2 weeks they say. Admins please delete this thread of unhelpfulness.
Ahhh shoot I wish I had seen this earlier! I had the same problem after flashing Smooth Ion. It has something to do with entering CWM with low battery and then draining a considerable amount while flashing. What worked for me was downloading a battery calibration app and then charging until the voltage showed 4190V (max for our phones) and then hitting calibrate. Sorry I didn't see this earlier!

Battery drain by unknown usage

Hello guys,
I'm having issues with my battery when using the same ROM more than 2 days. I explain myself, my problem is after a complete battery cycle (from 100% to 1% then charging...) my battery drains drasticaly (look at the screenchot). I did a reboot and it dropped from 95% to 30%. It happens to me on these ROMs (Rootbox, Carbon, SlimBean, Illusion...) I use KT kernel and sometimes BMS but same result. So i dunno if the problem comes from the ROMs or the kernels... I will look further into better battery stats to see which app is causing this.
Thanks for helping and sharing your stats !

I would try a full cycle or two with the stock kernel.
Or if you want to go one step further. Backup everything, nandroid and Odin back to stock and try a full cycle on that.

You could install Wakelock detector, [https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en] maybe its some crazy thing that eating battery.
Try using intellidemand as your governor on kt kernel, i was having problems like you until I used that governor.
Hope this gets resolved

Thanks man for your help but I think my problem got solved by doing 2x full battery cycle with stock kernel (I cross my fingers ). If the drain issue still comes after that I'll try using intellidemand as my governor!

After two or three charge cycles if your battery problem persists, it's most likely an app draining your battery. Or worse yet, your battery is shot.
