iPhone 7 battery drains really fast. No longer charging.

Hi everyone,

Several months ago my I unboxed a new iPhone 7, then about 2 weeks later it started draining the battery so quickly you could almost count down in seconds along with the battery percentage as it dropped. While the phone was on (but draining) I could plug in a power source and it would slow down the battery usage but the battery percentage would still decrease with power connected. Once the battery was drained and the phone was off, connecting a power source did nothing. No charge icon.

I have done many iPhone repairs in the past so, instead of sending it back to Apple (which was a mistake) I replaced the battery and the screen hoping it would resolve the issue. However the same issue happened.

Apple have made it very clear that they will not touch the phone due to the replacement parts. I know, I know, I should have sent it back to them under warranty.

Has anyone else experienced this same (or similar) issue with an iPhone 7? Or does anyone have any idea's as to what could be causing this issue?


Answer this question I have this problem too

Is this a good question?

I have experienced something similar with my iPhone 7 Plus, however I replaced the battery and it seemed to fix it. Firstly, try doing a full factory reset, as there may be some settings that are draining your battery, and this could resolve any software issues.

Maybe there's a problem with the power connector? Try replacing this part and see if the battery holds charge.

I did try a full reset but it didn't help. Since I sent the phone away two iOS updates have been released, maybe one of them fixed a software issue that could have been causing the battery problem. I'll try updating the iOS before replacing the charge port.
