Now before anybody starts about S24 having being a great phone and amazing performance, …
I own the exynos chip version ( I live in the EU ) and the heating issues and battery draw is disqusting. I have had it for a little over a year and the battery will go from 78% at 1pm when starting afternoon shift to 24% at 10pm after finishing my shift.
It used to last 2-3 days with my usage, nowdays it can’t go over half a day with me not touching it ( I have syncthing running and tasker to disable/enable syncthing depending on conditions. And home assistant to look up automations that I have configured to use the least amount of sensors as possible ).
All I need in a phone is good battery life ( atleast a day with syncthing/tasker and home assistant running in the background ), smaller sized screen with an oled/amoled display ( I tend to read manga and webtoons on my phone ) and possibly a snapdragon chip for occasional pc game emulation ( indie games ) using fex/gamenative.
EDIT: The main problem I have with the phone isn’t the battery life, it’s the overheating issues that made the battery life to degrade rapidly that I have the issue with.
And once again, fixing the battery won’t fix the overheating issues that led to battery degradation in the long run.
The exynos chip in this damn phone rans far too hot, the amount of times it heats up in my pocket doing nothing is far too common.
On another note I’m not technical enough to use an ifixit kit.
The phone shouldn’t be “heating up in your pocket doing nothing”. Something is running in the background that’s destroying it. Check battery usage and see what it is.
