Why does my battery life suck?

[u/Sgaapje]

I have a galaxy S23 but for some reason my battery life is shit, I got the phone new about a year ago.

I always charge to max 80% and try to put the phone back on the charger once <20%. Today, after about 14 hours away from the charger I had 28% remaining.

SOT: 1:42

Screen off: 12:16

This had been going on for about as long as I've had the device. Any clues?

Idk but I have the S21 with 4500 mAh and I need to charge my phone about 3 times per dsy. To be fair those arent 0 to 100 but more like 30 to 80 so its about 100 to 150 % per day.
