maserati Comparing with 6S (iOS 11) all my setting are the same and I set my iPhones to sleep mode when I go to bed. I do have 2-3 % battery drain on my X which I think is cause by Face ID setting and is normal (?). Of course my situation cannot be compared with yours.
Previously on my 7 plus, if i went to sleep with the phone at 100%, i'll wake up with it still at 100%. Mind you cellular coverage in my house is marginal at best and my wifi is always on at home too.
I'll be more than happy if my x can only drain 2-3% per night. But recently because of the mail app and now waze, it's been draining about 20% a night.
At least the gmail app is running normally, taking up 3-4% of my battery usage per day.
Don't get me wrong, I'm still enjoying the phone and am still in love with its looks and size. If I had to choose another phone, I'd buy the x again in a heartbeat. But it is still very disheartening to be made guinea pigs for their developers after paying so much money, being spoilt all these years by apple knowing that once I take my new iphone out from its box and get it charged, it will just work. Period. Which is also why people pay a premium price for iphones over other makes and models. The current experience doesn't justify the premium anymore.
