you can do small changes and can bring battery life at moderate stage.
example: 1.if you don't have 5G network please go to mobile network and change it to 2nd option which is just below 5G/3G/2G. I am using S21 ultra but my data still 4G so I changed it and it help at some point. 2. if you have finished Sync your phone already then please drag screen then off that feature too. can use this feature just once 1 week while u r not using ur handset, like weekend night time and dont forget to switch off sync in the morning so ur data will be backup and update. 3. Go to connection > more connection setting . here please close Rich communications and nearby device setting if not in use. 4. while u go to dice care click Battery and go to individual app and check "if using background data " is on ,please off according to ur choice .
Have you contacted p.o.s for help or samsung direct as sound battery issue. I get 1 4g bar inside home but as soon as outside full signal so I turn airplane mode on, use WiFi and WiFi calling with WiFi preferred then when out switch back. Nil to poor signal will drain but not to rate you describe.
I've contacted both Samsung and Three. Three say there's no issue with signal in my area (No true, I'm lucky if I get 3 bars out of 5 and normally it shows no 4G on network). I haven't got unlimited WiFi at home so can't leave it on, unfortunately.
Samsung say I can send it for repair, but it might cost me, even though battery is under warranty.
Thanks. * I have Dark Mode on already * Nearby Scanning is already off * I've used wallpaper that comes with phone * Only thing I have on is Bluetooth as I wear a smartwatch which it syncs my health data to my phone.
I will try and purge some apps to see if there's any I don't need. Do you know of any that can be uninstalled that are standard to phone?
