Mi 8 poor battery life (not even 1 day) - Xiaomi Mi 8 Questions & Answers

Hello,
As described in the Title the battery life on my Mi 8 is very poor. From the beginning it really wasnt that good and I could not understand how people could say it has really great battery life. Now as it gets older and the Battery degrades, it has become worse and i cannot even get trough the day.
AccuBattery says SOT of 3:20 and a battery capacity of 89%
Any suggestions how to improve Battery?
Thanks

Well, I had similar problems on MIUI. First try to flash a custom kernel which gives you some tweaks, performance and battery update. If the battery is still very bad go to AOSP ROMs

G901F Best Battery Life Rom Discussion

I made this thread so that other users can discuss which is the best rom for G901F in terms of battery life.
It will save users the hassle of installing roms and then testing them for weeks to find out which is best.
So let the discussion begin!
Cynogenmod
I installed cynogenmod 12.1 where the battery life was not great, however then went back to cynogenmod 12 and battery life was much better. However after using the rom for a couple of months i have seen a steep decline in battery life even when phone is sleeping.
What is other users opinions on other roms?

Did you recalibrate the battery after updating to 12.1?
I use Simple GX Rom 1.4.1 with Kernel.
Battery life is very good. Nearly 0%/h in deep sleep.1-2% over night (9h)
I tried Nova 1.3 with stock kernel. Batterylife was a little bit lower than SimpleGX.
About 0,7%/h in deep sleep.
With Stock BOH4 Rom (Tmobile) i have lost 15-20% over night

Battery Kernel

Hey all,

for my g6 h870 battery life is baaaaaaad, unless I'm running on android 7,14 (fulmics from) then the battery life is amazing. but on newer android versions like 8,9 and 10 screen time is up to 2 to 3 hours with a brand new battery, with old battery I was getting 1 and half hour of screen time. so my tip to you is to try fulmics rom, ofcourse a lot less functionality, but battery life should be very good

My h870's battery life is miles better than u said urs was on android 10. i finish the day with around 20% and start with 90%. And my g6 is 3 yrs old. Your phone might not b working correctly

yeah, when i checked on battery consumption, it shows me that "Phone idle" uses around 50% of the battery. Ive tried many different fixes but none of them worked. This phone idle thing followed me almost on every single rom I install.
Yesterday I installed xtended xq (android 10) rom, and the battery life is back to normal.

Battery life is very good if compared to what I've had before(aquarios 8.1), UI is smooth, lots of functionality. i cant compare it to havoc os, its been long time since I've had it. but I've read in comments to that rom that its generally better than havoc.

On my g6 I get pretty good battery life too, around 4-5 hours sot, using havoc 3.8. I don't use things like aod or ambient display. Smart charging should be disabled. Even if I set 'stop trigger level' to 99%, I get much worse battery life. The phone is around 2 years old.
G6 H870 noticed if I charge battery to 85 % or 95% I get bad battery life. If I charge to 100 % I get good battery life. On Stock and Custom. I think something wrong with battery calibration.
Is somebody else experiencing it?

Question Battery drain and actual battery of Redmi Note 10 Pro/Max MIUI13 v13.0.3.0

Hi, I have purchased a new Redmi note 10 pro but the battery seems to be draining relatively fast. I am on MiUi 13.0.3.0 update. There are some screenshots attached of the battery page. Also I was able to find the Actual Battery Capacity: 4997 mah. Can anyone please confirm that this is normal or not?
What is the over night battery drain percentage? And how much screen on time do you get in one full charge (100%-0%).
I bought a new device 4 days back. I'm on the latest miui 13. I checked on accubattery and saw the actual capacity to be 4700 but that app has been notorious for incorrect measurements.
1. I'd like to know what app you are using to get the actual capacity
2. I can't say how much your drain is from the SS. I can tell my experience. Im getting around 7-8 SOT % with 120hz. Overnight drain is under 3-4% max. I have debloated the OS as well so that might help as well.

Over night battery dain is 2-3% at Max I have manually disabled apps from running in the background. As of the SOT I am getting around 7-8 hrs (100%-10%) 120HZ
The only things to do are debloat Miui 13

Question crDROID vs ArrowOS battery life

Which ROM has the best battery life?
I have been using crDROID and the batter life is comparable to the stock MIUI. I tried ArrowOS for a little bit and it seemed to have longer battery life. I didn't use ArrowOS long enough to find out if it did truly have better battery life.
What has been your experience?
Battery life depend on personal use. Which differences with SOT have you seen?
With CrDroid (default kernel) I have between 4-5 hours SOT
imho too short. I want to try sleepy kernel first before I decide another rom

Like I said above, I didn't use ArrowOS long enough to know. But what I do know is that with the screen off, I lose 1% every five-ish minutes with crDROID and MIUI. ArrowOS didn't do that with my limited experience. For SOT, crDROID estimates 7 hours. I believe its more like 5-6, similar to your experience.

I didn't test crDROID.
but I have used Arrowos for 3-6 month it's ok ROOM but sadly no MIUI camera support on it, the battery life is great at the start but get shorter after long use, (maybe because of google play Update??)
"projectsakura" is way better if you want MIUI camera.

Did not try crdroid but I flashed ArrowOS 12L and can't tell any battery drain. Installed it 5 days ago and still have 20 odd per cents of battery left, waiting for the first full charge. I do not use any google apps/ services (gapps or else).

Which is the best custom rom for battery life?

Hi,
battery life for me it's very important: I own an S10e that has a very small accumulator.
I've used Orel6505 Pixel Experience with a good energy consuption and now I'm on PixelExtended. With the latest update the phone lasts more or less as the stock rom (max 3h of screen with almost all google services synched, 3 push emails and no social apps), not bad but I'm looking for something better.
My battery results still healty, about 80% of the full capacity.
Can someone share his/her experiences to let me know wich custom rom is the best for battery consumption?
Thanks to all
For me, DerpFest has good battery life but my phone has 2100mAh estimated battery capacity so don't take my word for it.
Have you tested this rom, and does the battery hold good on it?
can anybody please confirm no A13 custom rom has voLte working?
