My phone drains its battery very quickly.

My phone is draining its battery far too quick, I've had my phone a little over a year it heats up whilst charging, the battery power doesn't last at all, I've ran a diagnostics test and everything and nothing

Exactly the same here! - this is happening since the June update.

Do you perform a partition cache wipe after every update?

[murraj]

How do you do that?

Check Google/YouTube on how to do it.
Should do it after every update to clear all the rubbish,this helps with performance and battery

I would first go to support in the samsung members and their is a function call diagnosistics would uses that check the battery to see if you need a new back secondly check to see if their are any apps that are driving down your phones battery 🔋 and also check to see if your have any updates too. Hope this will help

May and June haven't been good for battery.
Also Google services is high.
Which is a battery drainer.
