My 4yo #Android phone warms up during regular use, to the point I can't hold it in my hand, and it's very slow, most likely due to throttling. The battery needs to be recharged twice a day, a replacement is already ordered and on its way.

I'm wondering if a new battery would fix the overheating, or I should be worried about something more serious (Nexus 5X?).

Newer Android versions seriously neutered CPU meters (for "security") so I can't say if something is hogging resources in the background

@michal the overheating is a typical result of excessive CPU usage and it's killing the battery. You can dig around in settings and find a screen that shows you which apps and subsystems (display/radio) are using the most battery. You may find some application that just misbehaving.

@vestige I don't know, things there don't even add up to a 100%

I just don't trust this. And 'htop' is not allowed access to /proc/ filesystem and my system is not rooted.

I just think that it's so old that it's been infected and now silently mines Bitcoin or something. I need to reconsider cleaning it and installing #LineageOS

@michal if you are using a custom ROM on a Nexus phone, it may also be that you are missing some proprietary blob driver that is required for hardware acceleration like video decoding or proper kernel power management.

@michal probably the battery, once overheated it starts overheating itself and is pretty dangerous
happened to me twice already
