I came from a 3 year old iPhone 6 and a NextBit Robin Android phone so the battery life is great for me. Not really experiencing the insane battery results that plus users have reported in the past though.
i was from ihpone 6s plus. during its time with ios 10, it can easily hit 7 hours even 1.5 years of using it.
For this iphone x brand new, i struggling to hit 7 hours usage with ios 11. i was expecting at least 7-8 hours of usage, but, it went from bad to worse.
This is what I got yesterday. Looks incredible in terms of the numbers, but not sure what to think of it. I didn't use my iPhone X like that much. It's not THAT good in reality, but neither is it bad. In fact, I'd say it's safe to say that I'm getting better results compared to my iPhone 8 Plus. Should mention tho that I believed the latter had a defective battery (it last the whole day, but nothing more than that). 😛
Anyway, apart from the numbers I would say it's all okay to me. As long as I make it through the day I'm happy. 🙂
I heard that some iPhone X users are facing battery drain and WiFi not working issue on iOS 11. If you are one of them and still facing battery drain issue on your brand new iPhone X, Then you should try some possible solution to Improve battery life of iPhone X before taking it to an Apple store.
