For most of us, the phone is more asleep than it' s in operation. That's why choosing the correct ROM & Kernel is essential for your battery.
I wanted to figure out which ROM is best regarding battery life when the screen is off and how to reach the best result.
I Started testing with the CM13 as it supports Xposed and Amplify, great batterysavers.
I'll Keep this updated per 1 or 2 days.
BetterBatteryStats Calculation.
The app to calculate the drain is called BetterBatteryStats, a well known app.
If I look at my stats: View attachment 0.2.txt I can see the voltage went down from 4402 to 4313 (-89) in 1223minutes. That's 60 x 89/ 1223 = 4.366%/hour = 4.4%, which is correctly showing in BBS in the attached file. Now I translate this to percentages: 4.4% voltage decrease x 5% battery decrease / 89 = 0.245%/hour battery. This is again correct according to BBS. I guess this is a fair calculation. the voltages seem to go up and down all the time, so I don't understand how it's an exact calculation but ok.
Settings
Batterysaving settings - Please KEEP IN MIND It's in a TEST Stage, probably things won't work if you Limit everything like I did, but I didn't encounter many problems =)
-Install Amplify and limit as much of crap you can possibly do. I limited the following to 999999 seconds (lol)
The wakelock names differ to every ROM. That's why I won't name them all. I'll update tomorrow the wakelocks , alarms and services I limited in the xiaomi.eu ROM.
Install Greenify: Aggressive Doze, Working mode: Boost, WakeupTime Coalescing, Deep Hibernation, Gcm Push, Greenifying system apps, Reveal Hidden sync.
And then hybernate all crap, except basic stuff the phone needs. I Hybernated for example: AudioFx, Google play services, live lock screen, nfc service, weather service, google service Framework etc.
General Settings: Wifi never keep on during sleep, BT off, NFC off, Sounds off, Vibrate off, Brightness minimal, no adaptive brightness, disable adjustments, no ambient display, no double tap to wake and sleep, sleep after 5 min, no battery and notification lights, % battery in statusbar, no sync accounts, location off, Developer options: 0,0x animation and duration scales, Play store: dont update, deselect app updates available.
Battery History App: I installed it to monitor at what exact time it decreases every percentage. So I noticed that from 100% to 99% it takes mostly 6 hours or so, while the rest is much lower (around 1 to 3 hours) You can save more battery by not installing this as it has many wakelocks.

Are you using cm13 snapshot or nightly(which build)? Also any custom kernel with it?
I installed the 20/12 snapshot, and installed the DragonXIA CM based Kernel

Thanks my friend, I have the paid version but I downloaded it from somewhere on XDA without paying, and amplify aswell.
I actually got 0,1%/hour with the xiaomi.eu ROM with android 6.0 with xposed and amplify and greenify and powernap. (android 7.0 is not supported by xposed and amplify) I will upload new details tomorrow!

Remove these attachments or soon you would see this thread as closed. Its against the xda's rules.
Hey team!
I wanted to start this discussion by knowing which setup you prefer the most:
Example:
1. Havoc OS
2. Shadow Kernel
3. Magisk Modules: GPU Rendering, LKT, Universal GMS Doze
4. SOT: 8-9 Hrs (Moderate usage, Pokemon Go for 2 hours, YouTube, WhatsApp, Instagram)
5. Idle Drain: 10% in 8 hours
6. Naptime, Servicely
I believe this will help people deciding people which setup to use!
Hope we can get a lot of feedback, thank you!
Since I dont care about battery life I just use the premade rom by dev
example
HavocOS - with kernel that comes with it.
No battery saver / profile etc.
Got 6-7hr sot 30hr+- bot
without details, its miui 9.6.25 oreo
I have unlocked the bootloader a week ago
I have a tried several roms like.
1.pixle experience
2. Lineage os
3. Miui beta
4.oxygen
5. Nitrogen
6.AICP
7. aosp extended
8. Pixel CAF
9. OMNI
10. VIPER
IN every ROM I have used the battery temp is always above 40°C at idle and full load it crosses 48°C . Is there any solution
My battery temp is never that much in any of the roms i tried.
In you case, check 2 things..
1. What is the ambient temperature of your room. You device cannot be below the ambient temp of your surroundings.
2. Some app i probablyrunning in the background. Check battery usage to spot any such app. Also uninstall any app that is not from a good developer.
my phone is a50s a507fn . rooted
before root my phone drop 1% every 2-3mins just by doing light use
so i try to root and also use various method for battery save and now i get about 8hours with medium use
i dont know if it is actually different and better battery than before or not
doing this cost many like lower resolution so every thing look bigger and some stuff can be out of the screen . darker screen ....
please if anyone can please tell me the different . i include the screenshots of betterbatterystat and stat in device care below
ok its actually better now

this is root for a50s
https://forum.xda-developers.com/galaxy-a50s/how-to/guide-root-galaxy-a50s-magisk-v19-3-t4001271
no root method
.change to Black theme
.turn off sync , nfc , bluetooth , location , ...
.no battery percent
.hide camera cutout - shorter screen (optional , simulate display with cutout , tallcutout)
.pixel off - amoled screen https://play.google.com/store/apps/details?id=com.anrapps.pixelbatterysaver&hl=en
.black wallpaper lockscreen
.turn off some unecessary apps notification
.no notification badge if you use other launcher
.battery save mode medium
.use low brightness (i only use around 5-15 when im inside , only 20-30 when outside , )
.low screen timeout
.disable app permission
.use adb to freeze, uninstall bloatware
.disable animation in developer option
.sd maid - clean up trash , may help your phone run better
.lower dpi - minium width (smaller means less dpi but everything will get bigger)
advance root method (optional , these things can improve battery but also change how the system work , could be harm when use too much , keep use them as least as possible)
.use titanum to freeze app or unistanll some unnecessary apps mostly is google apps that you dont use,some other bloatwares but you have to know about them before you want to freeze or uninstall them and dont touch samsung pay
.betterbatterystat - wakelock , sot , sensor , process track to monitor what drain battery
.greenify - disable background app
.my android tool (useful but risky , disable services ... there are some xda forums you can look)
.helix engine - cpu
.game launcher - fps, battery for game and apps
.l speed - tweak system
.screen shift - lower screen res
.app ops - to manage app permission
Nice....
I would like to discuss in this thread what the battery of our Xiaomi 12T Pro is like and let's share screenshots of the hours of screen on time, tips and settings to help improve the battery of this beast
I have an online shop, I use Instagram a lot, and VPN is always on and I am connected to the Internet with data
MIUI 14.0.1 GLOBAL
Amazing, best phone battery i ever used
i make about 8,5-9,5 hours screen on time on stock MIUI 14 and MIUI EU
Just added all apps (except whatsapp, gmail and telegram (messaging apps)) disabled in the background after 10 minutes of non-use (in battery options)
