I have the same problem, battery life on my iphone 6 ios 11.0.2 is 3-4 hours... my battery was replaced this week and still the same problem. Just saw this video, don't know what to say..

Exact same problem right after I updated iOS to 11.2.1.

It's clearly a software and not a hardware issue and Apple seems silent on the issue. https://www.forbes.com/sites/gordonkelly/2017/12/19/apple-ios-11-battery-life-sl ow-iphone-performance-ipad-problems/

OMG, I'm not happy about this. I returned a Surface Pro because MS would not address Intel-SA-00086 security vulnerabilities, so I downgraded to this iPad Pro- frankly, I regret that decision. The Surface was a better quality product in so many ways compared to this iPad (except in size, I prefer smaller) even with the Intel chip backdoor access problem. Maybe I should return this and wait to see what comes out in 2018.

Hi

If your battery is over 2 years old it will need replacing make an appointment at Apple store.

Or go to Support.apple.com for posting details use SIMCARD in other phone if you have one.

You may need to wait until after Christmas.

Cheers

all have the same problem!

What were you told when you took your iPhone to an Apple Store for investigation and resolution?

It is a disaster. The battery of my 6S becomes flat at the speed of the level light. Extremely disappointing.

Apple just wants us to buy a new phone. They will not fix the issue.
