Huge system battery drain

[HashDragon]

So I left my phone at around 90% yesterday night with both WiFi and data turned off with no apps running it background and when today I woke up all my battery was drained. I did some research and people suggested to delete google play cache etc which I did. I am still wondering about the real culprit and the reason behind this.View attachment 4582529

See if your CPU cores are maxed out using this app (https://play.google.com/store/apps/details?id=com.cpuid.cpu_z&hl=pt_BR). Post a screenshot from the first screen.

hi..this is the first screen.

Yup, welcome to the club, have a seat and hope that sept patch will fix it

hi..this is the first screen.

You have the same problem that I had. (Not bad as yours...). As you can see, all the core clocks are at maximum speed, draining battery. The solution is to change the 'scaling governor' from 'interactive' to 'ondemand'... But to do so you need to unlock bootloader and root the device. I did this last night and my battery is fine now.

You could also delete the cache+data from google play services, and reboot your phone (turn wifi off!). You will not have the problem anymore (but if you switch the Wifi back 'ON' it will come back after a while).

I see..well this sucks..this was not the usual case before, can you show me what a normal CPU profile looks like ?
also will this void my warranty if I root & unlock BL but not flash a custom ROM etc?

The normal cpu in iddle looks like the SS i've attached... It should increase clock when you're actually doing stuff, but, if the phone is iddle it should go back to the 'lowest' setting, which is what is currently in my SS.
And it will probably void warrenty, but I'm not sure... Good luck!

I am really surprised we are facing this issue even after having Android One. Wish I had waited and gone for Poco.

This issue was happening in pixel 2 as well, months ago... There are people here in the forum that own this device and does not have the problem... So maybe we're unlucky?

how to do it? i have kernel auditor installed with rooted a2.

Go in the 'CPU' tab and change the 'scaling governor' from 'interactor' to 'ondemand' (you need to apply this in two itens, each item control 4 cores - its under the section "Big Governor" and "LITTLE governors") then reboot device.

Use cpu-z to confirm if the value was indeed changed.

Quick solution is to reboot. Fixes the issue but it gets triggered again! Submit a ticket on the feedback app.. a lot of people are affected by the CPU maxing out

It is just $50 more expensive and is available in India. No BS.
Xiaomi doesn't even reply to people or keep them updated like OnePlus does about the current issues and ETA of OTA.

 

[terragady]

A2 is like 230$ and poco is over 400 on gearbest for example. OnePlus yes sure they reply but they are lying all the time.

+1 , this sucks!!!

Poco will have their own bugs, don't worry.

this is Xiaomi world, good hardware, good price & lot of bugs.

I'm curious as why in CPU-Z, my processor is labeled as SD636 2.21ghz but the model is 660.

 

[mariotwj]

As for the cpu frequency, mine was like that until I stopped using the fingerprint and switched to trusted face.
It didn't get stuck ever since.
Now it discharges by 12% per hour without games, give it a try :good:
