I am the person who changes devices every 8-10 months, before purchasing S20 FE 5G, thought that I'll be using it for long like 2-3 years, but the battery backup is worst I've ever seen on any phone!! Its a mental pressure how quickly it drains and I have to charge it again.
Now people will come and give steps to calibrate battery and all other stuff, Those steps are just useless af!
