Firstly , I am so satisfied about screen on time. can get more than 10hours with global stable 10.0.2.0 device is 3/32 variant. But I have a serious problem. Once I let phone to sleep from night to morning I lose 4-5-6 percent of battery. I had redmi note 3 pro before and I wasn't losing battery at nights. Tried to find a solution for it and flashed with miflash and both twrp these global stable roms( 10.0.2.0, 10.0.4.0, 10.0.6.0, 10.2.1.0 , 9.5.19.0 , 9.6.3.0 ,9.6.4.0 )
Does any one of you know the reason of these battery loss. And I have strong signal btw. Also is there any custom rom that provide me perfect battery life ( sot and cell standby both) and stability. I dont need it to be fast. Thanks !!!
I'm also a former RMN3 owner. Most of the custom ROMs I've tried (none of them MIUI based) don't match the standby battery endurance of the older model. I just beared with it.
If you want to look for the best, I think that's indeed stock or MIUI-based ones.
I don't know if this happens only on me but I get 7-9 hrs SOT on my Xiaomi EU based custom ROM while I only get 3-4 on AOSP 10 based ROMs and the phone gets warm!
Also the brightness is very dim I have to always have it on 100% and still is barely visible.
When I do that the motherboard area of the phone gets very warm and the battery drains much faster.
I have the China AI version with 6gb of RAM and 64gb of storage
Hi guys been using miui 12 for two months and I don't want to go to custom roms. is there anyway to get SOT like miui 11 android 9.
now only getting 5-6hrs at most.
what will i do.
is Chinese rom better than Global?
Using stock MIUI 12.0.3
I have never run the battery down all of the way, but by extrapolation it looks like I can get about 10 hrs, assuming just screen time with minimal standby.
With my normal use, overall I get 2 full days on a charge, each day with 3-4 hrs SOT.
Unplug early in the morning, and plug back in evening the next day.

Have you optimized apps ART cache through ADB or at least done factory reset after update? Cause I'm getting low SOT (on EEA) too and considering one of those options... or both

Ever since I upgraded the battery life has been terrible and I tried the ADB method, and honestly I haven't noticed that much of improvements, now I'm considering to format my device.
so it's miui 12 for redmi note 8 pro ****ty? i should stay on miui 11 and not upgrade mine?

it happens with every major update where the battery life and the performance become a little horrible, a factory reset is always advised.

For me miui 12 has better battery life then miui 11.
I'm getting 10 hours SOT easily and am very satisfied with the overall performance and gui after debloating.
I kept data but cleaned system, cache, dalvik and vendor.
But clean installation is as always recommended.
Another thing, give battery life a couple of days of use to normalise after upgrading.
In almost every case after upgrading, especially dirty flashing, there's a noticeable increase of battery usage as the system has to rebuild caches and kernel to stabilise.
Especially the media scanner is consuming power in the background depending on data storage. Adding .nomedia files to folders you don't want to be indexed helps a lot.
Overall, don't judge the battery life too soon after upgrading.
Hi,
Did you guys find out a solution?
I have the EU rom 12.0.3.0 on my Mi 9T and I still have a 5-6 hours SOT.
The battery is not draining when I put it on flight mode which is good.
I do have a normal use of my phone: whatsapp, emails, internet...
I have as well restricted many apps in the background.
I dont know what to do more to have a better SOT (2 days without charging my phone), except coming back to miu10... which is a shame because i bought this phone to enjoy last os.
Almost most custom ROMs for my Whyred don't seem to be work well at all for me .
My phone gets very hot I only get 3/4 hrs of SOT even with battery optimized option on custom kernels.
The brightness is so low i cant see when I'm outside, I have to constantly have it on max and the phone gets so hot during that .
Also pixel experience gets so laggy most of the time scrolling through open apps constant lag!
And that's not because of faulty battery
In MIUI 12 latest beta with custom kernel my phone wont get warm and i get max 6hrs of SOT which is very good for a 2 year old battery.
I don't understand what seems to be the issue maybe because I have a global model?
Tried pixel experience, evolution X , lineage OS same issues ...
My friend with a Redmi Note 4 gets 7 and 8 hours of SOT with smooth performance on his 4 year old device why cant I?
So I've used MIUI, both global and xiaomi.eu, and also CrDroid custom ROM, all roms in android 11 and 12. What I've observed is that idle power consumption is higher on Android 12, I've used Accubattery but also other apps like Charge Meter to measure current used, and there is around 25-30mA more power used by Android 12, so when I'm doing nothing I can see around 90mA on Android 11 and 120mA on Android 12, both in MIUI or custom ROM, so maybe it's something to do with Android 12 itself, or maybe the firmware used by Xiaomi since Android 12 is just worse.
