Three different phones and neither are performing well in terms of battery life. How’s yours looking? 
Amazing. I’ve been on it all day since 5am and it’s 10pm now and still 23% left.
My 6S would have died after lunch and would be dying again now.
Im currently at 3% with 6:45 of usage. A bit disappointed as I was expecting a full 2+ hours extra than what I got out of my 7. (usually 5-6). I know this will never reach the advertised 12 hours...but was hopeing it could at least do 8-9 and FINALLY be a true all day phone.
Guess were still no there yet.
The battery is about the same as iPhone 7 plus.
