Android new battery but half capacity.

[petike0707]

I'm running the Mi 10T Pro on a custom ROM and I checked the config files with root file manager, and the phone only charges to 3300 mAh which is noticeable because it should charge to 5000 mAh. I just changed the battery to a new OEM one. I've tried custom ROM, brand new firmware.... Everything... still can't fix it though, please help!

have you tried a custom kernel?

Pixel experience ( a ROM ) comes with a custom kernel of it's own!

What if you reflash to stock firmware?

Are you sure it is a genuine battery? I've personally been sold a supposedly OEM battery by a reputable store that turned out to be a fake. And do you know when the battery was manufactured? If it's "new" but actually spent the last 2 years in a warehouse it will have lost capacity.

Just speculating about possible explanations

I'm currently out of town for a week but when I'm back I'll flash MIUI, I've actually thought about that as well. I don't know when they've manufactured the battery. Do I have any way of getting to know? But still losing 40% capacity is crazy. I'll report back if I may.

all custom roms comes with a custom kernel. but kernels can react differently on different phones. i saw on xda that there are just kernels that are avalable, you might want to try one of those as well.

How are you measuring the milliamp hours of the battery? I've never had a phone that shows mAh of my batttery?
