Disable critical battery shutdown android

[Propphet]

Hello, just as the title suggests im looking for a way to disable the "critial battery shutdown" on android (8.0).

 

I know that this can harm the battery but i need it to drain the battery to 3V (Default 3.5).

 

I have seen tutorials for android with a low version but cannot find a solution for android 8.0.

Why not hook an LED up to the battery until you have 3V?

You cant. I am not sure what you are trying to do but I hope its not one of those "battery recondition" crap you see dime a dozen on youtube. If you are trying to do that, just dont.

Because I want to use battery from 4.2xx volt -> 3.0 volt to get a bit more use out of 1 charge.

Well there is a reason why you shouldn't discharge a phone battery to 3V because if you do, they can go poof (and they will, experienced it before, you don't want that).

 

If you want more battery life, give it a bigger battery. The device shouldn't care about size, only voltage.

Its an basic Lithium-ion battery right? Why can I by default discharge my powerbank to 3 volt but not my phone.

That it can go wrong I understand and have dealt with in the past (overcharging), just not finding a way to auctually get it working now a days.

The battery calibrations are crappy indeed, just trying to get a few more useable minutes out of a already good battery.

Depends, you can also find LiPo batteries these days.

 

Powerbanks don't need to deal with high-current loads (unless it's a very strong one, but those usually don't discharge to 3V) while in devices, you can easily see loads of 1.5-2A, you don't want those loads to happen at 3.1V.

They are usually spikes, not constant loads which batteries usually don't handle very well because more amps usually makes the voltage dip. It's better to be safe than sorry.

 

Just don't take the risk and upgrade the battery.
