Battery Drain/Usage

I know I sound like a broken record, but the S20 5G that I have, has the worst battery I've ever had on a phone. 

Today, in less than 2hrs, my battery has drained 50%, while I've been using it. As can be seen in my screenshots.

(I've purposely used my phone a lot today, to test this, as it's been an issues since I got phone last august)
It went down 5% in the time I wrote this post.

I know I live in an area that has a bad signal, but there clearly must be a flaw/fault in my battery. 

I'm not really asking for advice, as Ive tried everything possible (factory reset, cache, power saving, deep sleep). 

I'm writing this to see if other people have such a bad experience with their phones.

Let me know, if mine is just an exception!

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 .

Hope it would help.

Thank you and stay safe.


Hope it helps.

Here are some tips from me:

• Keep Dark Mode on at all times if you don't mind.

• Go to Settings, then Connections, go to More Connection Settings and turn Nearby Device Scanning off (it wastes a lot of battery).

• Uninstall any unused apps, it will save memory and reduce the background battery drain.

• Use a darker wallpaper if possible.

• Turn off NFC, Wifi, Bluetooth and etc when you aren't using them as it will save lots of battery.

Please let me know if you see better battery life on your phone after you use these tips. Hope this helped!

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.

I lost 50% battery in 2hrs, so that's definitely not normal.

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?
