I would say it could be any number of things, however the question is, what have you changed recently? Any updates, new apps?
Also, with this increase have you seen any decrease in your battery usage? I will have 70+% android usage sometimes but battery doesn't drain any faster. This is a normal thing for AOSP especially. Someone noted that they had high A.S. usage on a stock Nexus 4g.
This may just go away with a days usage, but be sure to check for partial wakelock. This option is in Spare Parts app not sure if its built in to MIUI. The wake lock is what kills your phone, when an app goes bonkers and keeps your phone awake.

True. Miui has updates every Friday. So yeah, i updates last Friday. I switched from tiamat to savagezen just so i can fix the high usage but to no avail. I can't check battery partial lock because miui has battery stats issues right now.

In addition to what imheroldman stated, charging your device will oftentimes cause your android system usage to spike, but 20% is nothing to be concerned with.

[Q] G2 Battery Life Issue

For the past couple of weeks ive been having issues with the battery life on my G2. I used to get 12+ hours of battery life on it but now im only getting about 7 or 8. Ive tried recalibrating the battery, clearing the dalvik cache, and changing settings on certain apps but that hasnt seemed to make a difference. Ive noticed that at the end of the day, the android system takes up a huge chunk of my battery. Any ideas?

I've had the same issues as the builds of CM have gotten higher in numbers. The ROM that's given me the longest life is the stoock Gingerbread rooted ROM. I switched back to CM because oof the Text MMS & them always being Slideshow issues as well as no ability to stoop the phone from vibrating when I'm on a call. Same issue with CM too actually.
I'm bumping this because I feel your pain.

you can fix that in call settings you know!

Are you running CM7? If you are, open up spare parts and look at the battery information under Partial Wake. See if there's something tying up the system.

There are a few things listed but I dont think its anything that would eat a whole lot of battery. Should I be looking for something in specific?

Anything that's more than a sliver is eating the battery and keeping your phone from sleeping.

I'm getting 24 plus hours on glite which is aosp also. Maybe the battery is finally giving up the ghost. They do have a finite amount if charge cycles. If nothing else has changed and all things being equal to your 12 hour charge cycles maybe you could try a different battery.

Finding apps keeping GN awake?

With ICS what is everyone using to figure out what apps aren't letting the phone sleep properly?
Spare Parts isn't working.
I've tried uninstalling about everything and I can't get this phone to sleep.

This is exactly the post I wanted to make today, glad I searched this one out.
I have few apps installed, and battery is going well for me. I'm a moderate user. I get about 20hours out of a charge.
I notice that even in airplane mode, my phone wakes up 3 or 4 or 5 times during the night for 5 or 10 minutes at a time it seems. What could this be? It's not data as I'm off wifi and in airplane mode. Any ideas?
Thanks all.

I've also been experiencing fairly high CPU awake times and was curious as to how I could track it down. Haven't found anything much yet in the way of apps, but I've turned off a lot of unnecessary Google syncing and an hourly sync of my Exchange account and it seems things are better now. I'm still getting awake times 1h30 greater than screen on time though.

I am seeing high "Keep Awake" times on Android OS Spare Parts force closes when I try to check Partial Wake usage so not 100% sure what this could be.
Wondering if this is the cause of some lower-end battery life we're seeing. My only thought would be LightFlow that is causing this (maybe to wake up for notifications). I thought I read it somewhere, but not sure if it was debunk'd or not.

Kernal (Android OS) Battery Drain

Hello
Just bought the htc m8 a month ago and has been an amazing phone. Except for the past few days the battery has started to drain way faster without any use. I installed gsam battery stats and added some screen shots.. Any help would be appreciated.

What programs are you install recently? Maybe problem is in one of them? Try to delete programs one for another which were installed recently.

But based on your screenshots (and assuming) you do use your phone from time to time than I think its fine
But do you have a custom kernel installed? If yes, have you tried to turn off pocket protection? It may help

Well i found the source of my problem. It was HTC Checkin Service that was draining my battery. Anybody know what i can do about this to fix problem? I tried greenify but that didnt work.

Try disabling the service, if ca't maybe freeze it using titanium backup?
But I think that should be some rogue app that's trying to make use of that service but I'm not very sure. I don't have that issue on sense based rom nor stock at all

Phone always awake & massive battery drain

So I've had this problem for a while now where the phone would be awake for longer than my screen has been on. I would usually get around 10-12% of standby drain overnight.
But since this morning the problem has gotten way worse; the phone has been awake for pretty much every second with 20% overnight drain (I've attached a screenshot below).
How should I go about troubleshooting the issue?
I'm using the Indian variant with 6 gb and I'm currently on MIUI 10.0.2.

Battery Drain Because of Continue High Cpu Frequency Bug
Some Persons Solve this Bug in Miui 10.0.3.

Not solved!
I have also Redmi Note 5 global version with latest MIUI 10.2.1.0 stable and no root just unlocked bootloader and face the same problem!
A big thumb down to Xiaomi.
Maybe chinese try to spy people? Bugs like this should be addressed asap but it seems they are still in place, version after version.
With this big battery we should not face issues of this kind and have battery life over 2 days if this bugs would be resolved!
There a question in my mind: why the hell all manufacturers go for encapsulated phones where you cannot take the battery out??? Devices need current nonstop, even when they're off, for what??? Conspiracy?
Still, what we should do in order to repair our problems, without rooting if it is possible! I know rooting solves a lot of bugs but I'd like to keep it simple.

Something is running in background, try to figured out which app is awake by looking into running services under developer option and then close running applications
S.off your phone for 5 mins and then reboot your device
