Apple iPhone 6s on iOS 11.0.1 - GSM-Forum

ScyberMhaster · 10-03-2017, 05:03

Hi! I just want to have some help from experts. I have:

Apple iPhone 6s running with iOS 11.0.1
Already Replaced Battery (2 pcs.)
Already Replaced U2 IC

I am having issue with battery drain. I don't know if this is a software problem or the hardware itself. But here goes the story.

I am experiencing Rapid Battery Drain and Not Charging with Original Apple Cable, and Intermittent USB Connection. So, I changed the U2 IC.

All in good now. I can charge the phone with original cables, restore, etc.

After I change the U2 IC. I did not restore / reset the Apple iPhone 6s. The CPU gets hot, literally. I never installed any graphics intensive apps. So, I DFU Restore with 11.0 and update OTA with 11.0.1 and Reset All Content and Settings. The CPU gets back to its normal operating temperature.

But my problem is that:

1. There is no Battery Usage even after hours of using the iPhone. (Since)

2. I am experiencing fast battery drain. But not compared to the Rapid Drain I experience before changing the U2 IC. It's far different.

- Around 1 Hour Usage (Normal), and 7 Hours of Standby (100% to 85%)
- Percentage Drops within 2-3 min. of usage.
- No Games, etc.
- Interchanged Battery, still the same.

I never DFU Restore to 10.3.3. I hope this will resolve the issue. Please help me for other things I should do.

Did you check for component short? try to connect to power supply and what is Amp consumption
