Well with barely any use today (less than 10 minutes), I'm down to about 85% by the evening on my 6s Plus. I think most of this is due to Apple Watch connectivity. My bigger concern is that with the screen on, just browsing message boards etc, the battery is just dumping. Probably 2-3 minutes per percent. It's pretty crazy. Screen brightness is around 25%, if that.
So it seems like my issue is screen-ON battery life. That doesn't sound like a hardware issue. It just sounds like the 6s Plus has inferior screen-on battery life for me. Bummer.![]()
My 6S+ devours battery when web browsing compared to my 6+. The performance of the A9 is ridiculous compared to the A8 but it seems to take a toll on the battery.
