Battery drains very quickly

Hi all
I noticed that the battery runs out quickly.
It holds only 12 hours in normal use.
While I was at 48 hours with my Huawei mate 8
Is there a solution to this problem?
I have attached the phone version if it can help.

Wait bro, your firmware version is outdated, latest Lollipop firmware is 2.20.40.184, but yours is still running 2.20.40.90, update your firmware first then compare your battery stats from your previous firmware version.
How long is your SoT(Screen on Time)? Well, on a daily usage my Zenfone 2 lasts for up to 6hrs SoT(with wifi browsing, some gaming, 2g/3g texting including standby for almost 12hrs as well) so i think your experiencing average for this kind of handset.
Also note that you've posted on a wrong section, this thread should be posted on the "Q&A, Help, Troubleshooting section".

This phone generally has **** battery life for majority of people, there are every few people who see any decent battery life (like above). There are no solutions for good battery life for this phone.

I wouldn't recommend somebody (even less a new XDA user) to flash a beta firmware. Only the user itself should decide if he /she really wants to try beta software.

Comparing this phone's battery to a Huawei battery is like comparing a Prius to a Tesla. I can go 3 days on my Huawei Ascend Mate 2 but it's a 4000mAh battery and a Snapdragon chip compared to a 3000mAh battery and an Intel chip. The ZF2 battery will never get better unfortunately

I was getting some serious battery drainage on stock rom - I upgraded to the CM13 ROM with Android 6.0.1 - Set it on Root and installed Greenify + Xposed Framework - Smart Booster - Battery Doctor - Configured them all and keep my brightness on low when in doors and automatic when outside. My battery seems to be holding much better now. I haven't used that Stock rom Beta release of 6.0.1 yet so I'm not sure if that'll help. Good luck!
P.S - I only installed the mini version of GApps.

Check for the running apps and disable those that are not of use to you.. There are apps that run in the background, just run those that you think you will be using always.

Disable touch gestures, the ones that let's you double tap to wake it up, I disabled mine and during the night, with wifi on, it only used 1% battery.
Also, disabling LED notifications would help.
To replace the double tap to lock screen I use Greenify's widget, need to find a way to let me wake it up by volume buttons too.
Any other battery saving tips would be great.

You mean 1% for the whole night? That's great!

Turns out it was 2 AM when I removed the charger, so it was about 4 hours and a half.

But still, that's very good. I probably won't get this low because I have crappy reception at home, but I'll check it anyway.

zenfone 2 is best for performance lag free most of the time .....but battery life sucks.... and about that ferrari and prius thing... my friends sony xperia z series especialy z ultra has awesome battery life it is also quad core processor phone ...it is also a beast phone ...but there stamina mode saves a lot of battery ... 8 to 10 hr SOT is normal for z ultra..... so clearly power managment is very poor for zenfone 2. i am using marshmellow cm 13 .. greenify... .. overnight drop is 3 to 4 %... but as soon as i start using it battery starts to drain quickly..... i have searched whole xda forum.. but everybody is talking about wakelocks, thats fine but during actual use also it is consuming a lot of battery....i am tired of searching

Finally google assistant arrived with stock official firmware N910TUVS2EQB1.

I just noticed that with the new update N910TUVS2EQB1 Google assistant came by default .
My device is not rooted i just updated google app from playstore and it worked.
So happy to see our note 4 still getting new stuff.

System service drain

I was convinced on the forums that my system service drain was regular until I took a look at my buddy's phone , he has a le s3 with 2 sim cards and his system service doesn't normally go past 80 mAh on a full charge . Something has to be wrong

This is a screenshot of my sot when I first got the phone

8 hours of SOT is really good. You can try installing Wakelock Detector to get a different perspective. Also, anything that uses accessibility services may harm battery life. Another thing you can do is go to settings-permissions-autolaunch and disable autolaunching of apps that don't need to be running all the time. You can see what apps are currently running in settings - app management. One last thing is that your signal strength isn't that great, so it may just be how it's supposed to be.

I'm in the same boat as you, only I'm running OmniRom. But yeah, had 8h sot, can barely make 6 now, android system is my second biggest drain, with 2+ hours of cpu usage.

I have tried and I have found that 7.1 to 8.1 do not have the best battery life.
I personally have been aopk 6.01 and been getting great battery life.
I did do a stress test I did gaming and blasting next radio 21 minutes use only 6% of battery.

I've tried everything , disabled all apps in auto launch , tried it with airplane mode on , enabled background resource control . Never go past 7 hours max screen on time . My screen brightness is usually very low throughout the day

What are all of these services ? My buddy has none of these

You are running stock I take it.
Different ROMs are going different services like you show.

Turned on battery assistance at about 80% , battery life drastically improved

This is now ridiculous

All eui is in the rom.
I have no problem with custom roms. (Omni,Aicp,Lineageos etc.)

I don't see the big deal you have 3 hours 57 minutes on screen time and 50% battery left you will get almost 8 hour screen time on that is well above average!

Went through a hard 12 hour process , finally unlocked bootloader , installed twrp and running lineage . Going to be testing battery life

I have the same problem with Eui rom. As long as the display is turned on, the system service will exploit the battery. Nobody knows that?
There are no such problems in custom roms.(Aicp,omni vs )

Flash Magisk and try Greenify4Magisk. It's gotta be some third-party app you're running, or you have a bad cellular connection. Are you getting full signal on your phone? Do you have LTE running as well?

I haven't installed many apps , just the basics like Snapchat WhatsApp Twitter and Instagram . I tried to flash magisk but that would mean uninstalling super su . I normally get around 3-4 bars but I don't use cellular data . I have Greenify but it doesn't seem to be doing much

Poor battery life after February update

Since February update I am getting very poop battery life, usually I used to get SOT of about 6hrs but now it's dropped to only 4.5hrs.
I have accubattery installed and noticed that battery use while screen is off is too much. Yesterday during night it drained 25% in about 6-7hrs of screen off and wifi off.
Anyone else also facing this issue?
Also I noticed since the update, apps are staying in the background usually even after 1-2hrs if I didn't remove the app from recent apps it was working in background but now even after 5-10mins of not using the app it's getting removed from the background.

Install greenify. Hibernate those apps. Might be some apps running in the background without you knowing. I'm on Feb update and I'm still getting 6-7hr SOT.

This has nothing to do with a security only update. I'm pretty sure the problem is caused by one of your apps which you've recently updated.
Install GSam Battery Monitor and BetterBatteryStats and see what's wrong.

Same here and I'm losing my mind. Not sure if it really is decreased or my brain is playing tricks on me. I haven't had the phone for too long, so I only had the January update for 2 weeks or so and I really feel like the February update decreased my battery life. I have set up Greenify and Amplify. I've also disabled sensors for Google Play Services with XPrivacyLua because I noticed that the body sensor was using a lot of battery for it.
Edit: Ok, I'm pretty sure I fixed it and I have no idea how. I just know that it got fixed after a restart, even though I restarted my phone before. And I'm pretty sure it was RCSService that was eating the battery.

Hi bro, I am also having the same issue. The device is installed with same apps that was before updating. I charged the device upto 90 and went to sleep. When I woke up after 7hrs the battery is drained to 55%. Android services and android system(RCS) took the battery. Did a factory reset and no issue. Still getting along with this. Any improvements mate?

Same here, that's why I reinstalled the global rom with january update only.

Yes, you will be able to get de OTAs because you are installing the official ROM, and bootloader will be automatically re-locked by the Mi Flash tool.

same here, i got 1% discharge in 6 minutes when i was in January update, but after i upgraded to feb security update, the phone discharges 1% in about 4 minutes. Yes, but the charging speed remains at 1% per minute.
I have to charge it twice, whereas a single charge lasted for a day. . i will wait for the March update

I have the same issue (mentioned in other thread with Blutooth) - and I have the same apps for couple of weeks (I am not a heavy user, app tester etc.)
If this is an app - it wolud be the update of it only...

Facing same issues. Dropped from 7.5h of screen-on time to 3.75h after February update. I wonder if it's time to move to LineageOS with MiNT kernel

Then i was also experiencing same battery drain issue, but i am not sure because earlier i have not noticed thats why just want to confirm, i think after latest update usage drain was more, i mean suppose if i play pubg on same amount of time in earlier stock 327 there is 5% drain occurred then after latest update on same amount of time playing pubg there is 8-9% battery drain experienced.
P.s.In idle mode i haven't seen much difference.
