so yeah after about a week using the s20 fe 5g with proper tweaking the results of SOT are as follows:

120hz = 7~7.5 hours SOT (10~15% battery left)
60hz = 8~8.5 hours SOT (10~15% battery left)

- mostly at home cause work from home lol
- brightness controlled as i feel auto is too bright for my eyes
- important chat and work apps are enabled others put to deep sleep
- most usage on single game epic7, whatsapp, facebook, youtube

i always try to ensure the back of the phone is not warm.

Heard the google feeds can replace the samsung feeds in 3.1 haha hopefully yes

Read the comments section of the videos also:

List of already tried methods by me or others. In short: problem seems to be solved, but some reports it not solved!
- firmware BUA5 (Jan 15 update) seems to solve the issue! Thanks for all feedbacks on this!
- firmware ATJ1 shown in the video didn't resolve the issue
- firmwares ATJ5, ATK1, ATL1 enhances touch screen problems, but still don't fix issues

im running on BUA6 no issues. so its a software optimization issue not hardware issue
