The S22 Ultra should have a good battery life in real world use.
I've seen some of the reports written.
For one thing, the battery and software go through at least a couple of weeks of conditioning. Learning usage patterns etc
Too many of the so called reviews are based on a few hours or a couple of days with a phone.
For me they are irrelevant and I take all those reviews with a large pinch of salt.
There's been a lot of thought gone into this years phones with regard to battery life. Even at times reducing screen refresh rate to minimal. 1Hz I believe which no other manufacturer does.
I will wait until I have mine in hand
Don't base your assumptions on these early reviews. Too many have agendas
I use an iPhone 12 Pro Max, Google Pixel 6 Pro and Galaxy Z Fold 3 as my daily phones currently. The Z Fold 3 does really well against those two and all the reviews said battery life is poor. Well I'm using it and it's not poor at all
