Battery skips 98%

Hi! Recently something strange happened with my battery indicator. I was using CM7, when it skiped 98%, so battery indicator went from 99% to 97%. Now I can't fix it. I have been using Modaco, CM and now MIUI since this happened. Wiping (anything) doesn't help so I don't know what else to do. I don't know why, but this really bothers me. Does anyone know what should I do to get this back to normal?

I Think that it is not so big thing to lose your nerves about ... Important thing is that battery works ok

Yea I know, but if everything else works, you have to find something to fix Maybe it's so frustrating, because I didn't notice anybody else with that kind of problem

You're right ... The problem is one of it's kind : ))

Help: Android system consuming 90% overnight... in deep sleep. Battery down by ~15%

I did a complete charge last night before I hit the sack. Battery was around 96%, today morning 80%!
I flashed stock ROM using TWRP, on first charge cycle battery is fine - just 1% overnight drain with 8 hrs SOT. On second charge cycle this issue hits me everytime.
All my radios are usually off (WiFi, NFC, Bluetooth, Data).
My phone seems to be in deep sleep a good portion of that time (See WLD statistics - attachment #1).
Android system sucks my battery during sleep and it was at 90% relative consumption when I woke up (See screen shot #1, Android sys has consumed 1840mAh!! This is ridiculously high for a phone that is apparently in Deep Sleep!)
Also attached screen shots from WLD for Summary, Kernal / Partial wakelocks & Alarms.
Device is rooted.
Going crazy trying to find out what's happening.
This happened with KangVIP and my current B180 ROM's which have great battery life as reported by other users here .

After you flased the ROM did you factory reset?

Just wanna note here that if you live in the US the huawei erecovery does not work. It tries to fetch a download link for 5 minutes before abandoning. Even in stock firmware

Today when I woke up, Android system was @ 92% relative consumption with 15% drain.

No, after flashing I have not performed a factory reset. I wiped before flashing.

Thanks. Got it.
Will try a factory reset before I sleep tonight and see how that goes.

Yeah, have massive Android system drain too.

This is an unacceptable level of drain. I get similar numbers. This is getting very annoying. I am spending hours just debugging this nonsense.
When did you install / reset your ROM? What is the build you are on? I have read some posts that suggest to let the system be for first few days since it is in a "Learning Phase". Mine is currently in that phase.
Also, I find that many users here are not facing this issue on the ROM's that I am on, but some users are. I have faced this in multiple different ROM's.
Hence, I suspect this is an issue of some setting that we have changed. This is the first thing I do after reset / flash - modify a bunch of settings.
After searching and reading a lot, I have not come across any solid solutions from anywhere.
Here's a solution from the other thread. But I don't have this in system/apps. So this goes down the drain.

Couple others that are worth mentioning,
1. WiFi causing the drain (Am currently debugging this, modifying options).
2. Format SD card on new ROM, or just remove it (Would be great if you could try this out).
3. Factory reset has not solved for most people, but for some. (Did they *not* tweak some setting after reset?)
4. I think much of this drain is experienced after, charging and during sleep after that!

I'm on stock B192, been there for a few weeks now... didn't factory reset after the update, didn't have this issue during the first few weeks. Just recently. I haven't modified anything out of the ordinary.

What value do u have for WiFi -> Advanced -> Keep WiFi on During sleep?
I had the battery drain till last night. Before sleeping I charged it completely, and modified this WiFi setting. Overnight I had only 2% drain as compared to +15% over last few days.
Battery looks good for now. I had the feeling that my WiFi is consuming more power than 4G (Need to verify if I am right). Currently observing.
I hope it is not one of those sporadic issues!

I presume u have been facing this issue at least over past few days now, not just a day or two.
Try toggling to Never. Recharge to full before you hit the sack. Lets see if that changes anything. This helped me, but need to observe for multiple consecutive days.

Will do tonight, thanks for the advice.

If you not absolutely needed, switch OFF Google synchronisation. Profiles - Menu - uncheck auto synchronisation.

That's one of the first few things I disable. Nor do I use backup.

The battery drain is back. Disappeared for just a couple of days.
Is there anyone who knows how to fix this issue?

I would request you to do a back up of your apps and then factory reset and then again flash the ROM but via dload method.
Everything will be fine.
Then you can restore your apps

Drain

Hello guys, im just new here and i have a little problem on my phone which is the battery...

The battery is beginnig to break down and fail. Replacement is the only fix, eventually it will get worse then quit on you.

Thank you, ive done calibration and seems to fix it a little, i think its just the device miscalculating the actual percentage of the battery, what do you think? Also to be specific , i just finished flashing a rom from lollipop to marshmallow back to the last version of lollipop .. problem doesnt seem to occure before i flashed :/

It would have been better if you had provided that information when you first posted. If you want help with issues, it helps for us to know the things that have been done to the device that potentially caused the issue.
Don't just say "I'm having "this" issue". This implies that the issue is a random issue that started on its own and not something you did to cause it.
It's better to say "I did "this" to my device, now my device is having "this" issue". This implies that something that you altered is causing the issue.
Failing to post the details we need about the situation leads to inaccurate or incorrect answers. It can even lead to receiving incorrect answers that don't help or answers that might make things worse for you.
If you flashed a ROM and then this started happening then yes, the battery may be out of calibration.
If it had started doing this on its own then I'd say it was the battery.

media.codec is draining my battery

Hello fellas, hope you're doing OK. I would like to share with you guys the issue I'm having couple of days ago. The media.codec process is literally killing my battery, draining nearly 25-30% (even more than SOT). I thought was a chrome issue so I uninstalled it and been using Samsung browser since then. Even so, the problem persists. Any idea how to solve it?
I'm on CRAP 8.0 Exynos with custom kernel (Notorious Kernel).

HI, I've got the exact same problem, with the exact same kernel... HELP, ANYONE PLEASE

In my case, I realized it was due to VIPER app. When you turn off Viper it ceases the drain.

Android system+OS battery drain

Hey guys
At the beginning of my use of the OP the battery was really impressing, I also managed to reach the 7 Screen. The last week the battery has started to disappoint me, I thought at first that maybe the fault was that I was browsing too much on Facebook but i found out that Facebook is not at all causing the sharp drop in screen hours.
Android System and Android OS are my biggest waste of battery and come out in 3 1/2 hours of screen time. What can be done to improve it?

Man that's bad, i one played almost all day Kingdom Rush and world of tanks and my battery was still over 6h screen time. i don't know how that was possible

How it's your screen off/active graphs?
Are you phone rooted? If yes, you can install BetterBatteryStats to see what alarms/wakelocks are waking up the phone when inactive or find the app that are draining battery.

When I was using a Pocophone I knew Qualcomm-related bug that makes bluetooth prevents phone to enter deep sleep.
Try to disable bluetooth before restart and see the battery life. Maybe it helps

Hi!
I know that this will be a little bit clunky but i had the same problem (and lagg issues too) when i update from 9.5.8 to 9.5.9. The only solution was reboot on Recovery Mode (you can activate the advance power option from developer settings) and clear/wipe the caches and dalvik.
I dont know in with version of OS are you but with Oxgen Updater (https://play.google.com/store/apps/details?id=com.arjanvlek.oxygenupdater&hl=es) update to 9.5.10 and reset caches.
Hope can i help!
PS: sorry for my bad english

Yes, im on 9.5.11. Always, after installing a OTA, I wipe caches. My OP is giving me arround 7 / 7:30 hours screen on time. Its simple and works for me!
