- I am having the exact same issue! The empty battery with a lightning cable screen does not show up, instead an iPhone just blinks when power button is pressed, like just "backlight" turns on. If I put it on a charger, battery screen (without lightning cable) shows up and starts charging normaly.
- Also, I am experiencing enormous battery drain. Usage time is something about 4 hours. It's just regular use, wifi browsing, mail and texting. Bit of a Facebook. Every two minutes, 1% goes down... My regular iPhone 6 4.7" has usage time about 6 hours.
- An iPhone overheats too. It's always, literally always pretty hot at the upper right back side.
Tried restoring couple of times, with Restore mode, DFU, Set up as new and the problem persists... I am currently on 8.1.2, downgraded from 8.1.3
I would like to mention that I've bought my 6 Plus yesterday (it was 8.0.2), and upon unboxing it only had 36% of juice. Am I wrong or new iPhone should never have less than about 80-90%? Maybe that f***ed up my battery when it was still in the box?
Thanks.
