Does your s21 FE's battery does rapidly once it reaches 15%?

[solivagant56]

My device's battery dies within 15-20 minutes if I keep using under 15%. Once it reaches 5%, it dies within 2-3 minutes if screen is on. Please verify if this happens with your device too or else I am gonna visit the service center.

Typical samsung ,it happens with almost all of the devices of samsung.

[Prateek500]

And also it happens with all of the brands which have fast charging

[Prateek500]

Try charging your device with normal charger or 10watt charger 1 to 2 times, it will recover.

Or turn off fast charging and superfast charging.

Also charge your device upto 85% it will hold your charge better instead charging to 100%

Hmm, am using S21FE, and the case is same here if i talk about last 5% drain.
For 15% i get around 20+ minutes easily if net is on, and brightness 60%, but most of the times 15% gives 30 minutes. Try using some routines so you can get 30mintues :)

Same thing with my S20 FE 5G, Warranty is over. So I stopped caring about it.
