S8+ Battery question

[TabEuser-uk]

Have an S8+ bought a couple of years ago from a friend as an ex contract EE as he had been upgraded to an S10. Factory reset with sim unlock to allow EE PAYG SIM

Running stock non rooted 7.1.1 with no issues apart from due to reading these forums I'm now paranoid about my battery.

For about 90% of my day it sits plugged into a charger acting as a wireless hotspot for other devices, when I am out and about it seems to hold charge well but if I am using video calling or running with GPS on i can lose about 20% an hour.

It's currently at 82.01% and 701 cycles using the SAM info tool.


Apart from that it's fine. No bulging, no software issues. Do I need to be concerned?

Edited, not 7.1.1, I meant Android 9 one UI. My tablet is 7.1.1

I think that is normal behavior. Every phone battery will lose its maximum capacity overtime. 3 years+ battery might need to be replaced if you have concerns. I have the S8+ as well with over 1000 charge cycles.. with moderate usage I can still reach 4.5 hours screen on time. Video calls and GPS navigation with screen ON will drain battery.
