Hi,

My S21 could not last through the day despite mild usage. If I don't charge my phone overnight, the next morning it will run out of juice. The phone will often overheat with a popup message "Your phone is too hot. Let it cool down before using Multi window again" during video call (not even game). Ironically, my current S10 never experienced this issue.

I have been to the service center 3 times, first time they updated the software and that solved nothing. The second time they replaced the motherboard + battery and the problem returns after a week. The third time they updated the software again saying is a different update. Spoke to a customer support and she told me they received a "few" units with similar issues.

I already formatted my phone 3 times in less than a month for a brand new phone. Not sure If I'm the unlucky one. Anyone here experienced battery drop and overheating issues?

Yup, it gets very hot when I hold on to the phone and have to resort to a casing. But now my Nilkin casing has a slight burn mark and I quickly send it to the service center (second time).

Can't remember the exact battery life left with Google Play Services in used, but it's usually between 40 to 50+%.

My phone has every little app except for the necessary one, I don't even play games on my phone.

1. Don't use multi window. - Basically during video call + browsing the net, my S10 never fails.

2. Activate Wifi Calling, off the sim card. You will still get calls if you use WIFI. This is to test if your modem having issue or reception is bad at your area so your phone keeps searching for base station. - Might try this after I collected my phone.

3. Remove all background apps. Especially the camera if on. Use the clear memory widget out of box to do it. - The phone is still moderately hot if I don't use video call, but this shouldn't happen as my old S10 never has this issue.

4. Are you using the phone while charging? - Nope, scare the phone will explode lol

Can try using the Samsung restart schedule, but if end up having to do that every time, I'm gonna switch phone.

Not sure why they didn't replace the modem, but the guy told me mine is basically a brand new phone coz it's a brand new screen, battery, motherboard.


So no one encounters this issue here? It is only applicable to S21?
