I get very bad drain every day. I don't know why..
Bad only if it is idling for the 5hrs, but obviously it's not? What's the SOT?
How is this terrible battery life.. after nearly 5 hours of use I would expect to be at 70% something. I mean I use my phone pretty heavily and I get roughly 15 hours on the batter or 5 hours screen on time and have 15% or so at the end of the night.. I guess I'm not seeing this as a problem
ive noticed some battery gain from running in high performance mode too, use to run in optimized mode. at first it seemed worse by a little, after a few days ive noticed my battery life becoming better.
I was too, and I can't claim that it makes sense. Performance mode should theoretically have the worst battery life. Someone on there forums suggested trying it for a week despite that and I did, and so far it has given me better battery life than standard with Full HD. Theoretically, it's possible that Samsung spent extra software cycles optimizing performance node's battery usage and made it really good, so much so, that it's more efficient than standard. Hard to believe, but that's why my experience after a week is showing. I'm only one person, and my usage patterns are different to others, so who knows if this will work for more than me, and then other person here who suggested it to me.I was under the impression that high performance mode was just the 2k and 10 percent brighter, gaming mode and video enhancement turned on. I run my phone with optimized 2k turned on brightness under half way as this phone screen is too bright. That always gave me better battery that high performance due to the screen brightness.
