I recently bought S20 FE 4g.
I am to much disappointed by the battery Performance of this Mobile. It is the worst battery Performance I had ever seen in Samsung mobile. Like you just unlock Mobile it drops 1%. You unplugged it at 100% and start using it in just 30s it drops 2% 3%.
It is even more worst when Mobile is heating up.
I feel like I bought a second hand phone/used phone. Dua to its battery and also heating issue.
