This has left my iPhone 7 and iPhone SE absolutely useless. 100% to 0% within 6 hours with only 10 mins of usage in this duration. 100% to 0% if I used it for 45-60 mins (only Call and Message) immediately after full charge. Only 4 mins of video recording made iPhone 7 heat so much that it has shown a screen with thermometer suggesting to cool down before using it further. I was forced to buy Android phone after all I cannot let this issue impact my job because of pathetic issues. Battery was never a strength of iPhone but often poor iOS releases are making me think about permanently moving to Android. Moreover, there are no updates from apple on by when it will be fixed except that reset thing which didn't work for most of us. Thanks but no thanks!
