T-Mobile Galaxy S8 brand new s8, questionable battery life

[kofman13]

i played with my new snapdragon s8 last night for like 2-3 hours and set everything up and i love it! the only worry is so far the battery drain is a little more than i would like compared to my exynose S7 Edge. I have all the same apps and accounts setup now on my s8, and just in the few hours i played with it last night the battery drain was more than the s7e was in the past with that same medium/high brightness and watching a lot of videos and installing apps. then last night, my new s8 on AIRPLANE mode overnight lost about 10-11% battery life which seems too much on airplane mode, my s7e exynos would loose only a few % overnight on airplane mode. maybe the phone battery needs to calibrate for a few days? maybe the OS needs to optimize itself more? idk. but right now its morning here and im going to charge it too 100% and see how it fares throughout my work day.

i also did an OTA update 10 minutes after getting the phone, i saw someone mentioned online i should format or delete cache after doing an update?

That's sometimes recommended after a major OS update but I wouldn't worry about it at this point. Just enjoy your new phone.

Always on display enabled by any chance? That would explain the 10% drain. Otherwise you have some app still open.

ah true, on my s7e i have night clock at night instead of full AOD, maybe thats the culprit
