I decided to install the Android 13 UI5 update the other day on my Galaxy S21 Ultra. Turns out it was an extremely foolish decision. The battery life has been absolutely decimated. It is draining so quickly that even if I have the charger plugged in while I am using the phone the battery level continues to decrease! The phone is barely able to even charge now. With the screen switched off and the phone on my bedside table it took the entire night to 'quick' charge. Its now about 3.5 hours since I unplugged the phone and the battery level is down to 59% and all I have done with it so far today is receive one 30 second phone call!! Its so bad that the battery level is decreasing about 1% every 5 minutes and that's when I'm not even using the phone!
On top of that the gallery is now almost useless. I take a photo or screenshot, and it just disappears into the abyss! I go to look in the gallery or send it on WhatsApp and its nowhere to be seen! Some time in the future it will then randomly appear in the gallery and I will then be able to view it and send it, but what good is that when I need to send it immediatly?
I see there are others on here complaining about the same thing. How on earth has this utter pile of tosh managed to get through testing??
