I tryed 120hz on 720p my phone died at about 5hours but with 60hz lasted 9hours 28 minutes is that normal? This includes playing zero games and on 4g service 5g is off using T-Mobile, adaptive battery, wifi power saving 1MB buffer log size always on display off

Could try putting apps to sleep or deep sleep

From settings > Battery and device care > battery > Background usage limits > sleeping apps or deep sleeping apps

Also I would optimize my battery settings

From Battery >more battery settings >adaptive battery [make sure it is on]

These phones need time to learn your usage. Beyond two weeks, I noticed much improvement. 20% battery after 16 hours off charger, of about 70% usage.

If you're quoting screen on time then 9+ hours is good from what I've seen.

2 day battery life is not 48hrs screen on time.  I average about a day and a half before it's down below 20%
