Original topic:

S21 Ultra poor battery life

Hi all,

Just wanted to find out whether my battery drain was normal! I have been using the phone for a week now, and there has been absolutely no improvement. I also no longer have a message within the battery menu telling me that it's still learning my usage patterns. 

The screenshot below shows today's usage. I even charged the phone a little more mid-way but am still only getting around 4.5 hours screen on time at 12%. I don't believe I've been doing anything on the phone that explains the short screen on time. Nothing intensive.

Just writing this has lost me a further 4%! Anyone else had this experience?

It's worrying that your phone is hot to the touch after charging. May I inquire what charger are you using? I use the official 25w charger and it never gets hot after a charge. If I use slower chargers like a non Samsung charger the phone does get warmer than normal but never hot.

I'm using the older Samsung adaptive fast charger from a previous phone. Think they're rated at 15w. I have a smart plug that's able to show me the wattage being drawn, and can confirm it's taking 17w with screen off.

I get around 30 hours with a Bixby routine to save battery overnight and I only charge the phone when it's around 20%

Anyone who says there battery life on this phone is OK. Are clearly delusional and not actually using there phone. its terrible drain drain drain. As always every year with a samsung flagship release we have this conversation over and over again. Poor battery life. No change at all. The very ultra poor battery life on this phone is the main reason for me getting shut of it. I'll never invest in a Samsung phone again. Rubbish
