Battery life on 33R update is pretty good. 25R battery life was jaw dropping... I think I've still hit 28 hrs with 5 1/2 hrs screen time with 10% left (no games or YouTube) overall though, it's still pretty impressive!
I have found the same. I can make it through 24 hours no problem doing pretty much whatever I need to do. Here are some screenshots from yesterday (on 33R), which include some gaming (Waverunner 2) and lots of high brightness. Still plenty of battery left. 25R had crazy battery. I don't know what they did but it worked lol
