iPhone 15 won't turn on after 5 days, displaying a flashing red battery icon

iPhone 15 won’t turn on after 5 days — flashing red battery icon


Hi everyone, I need help with my iPhone 15. It’s been unable to turn on for about 5 days, and I’m trying to figure out if there’s anything else I can try at home before taking it in for repair.


Whenever I connect it to a charger, the screen repeatedly flashes the low-battery icon with a tiny red bar, but it never turns on. The phone doesn’t noticeably heat up while charging.


Here’s what I’ve already tried:


Multiple charging cables and chargers

Wireless charging for several hours

Leaving it charging overnight

Connecting it to an HP laptop

Force restarting it at least 15 times

Leaving it plugged in for extended periods

None of these things have worked. The red battery icon continues to flash on and off whenever it’s connected to power.


I’m wondering whether the battery has completely failed, whether the charging port or charging circuitry could be faulty, or whether there’s another possible fix.


My questions:

Has anyone experienced this exact issue and managed to fix it?


Is there anything else safe I can try at home?

Does this sound more like a failed battery or an internal hardware problem?



Could Apple diagnose it without immediately charging me for a battery replacement?


Getting to an Apple Store is difficult for me, so I’d really appreciate any advice. Thank you!

Is this the original battery that came with the iPhone 14?


Best case, a new battery will get things going again. About $100-110 (U.S.)


If the Apple Store / Genius Bar is not convenient, an Authorized Apple Service Shop (AASP) might be an option. Diagnostics are normally no charge. You can find a list of authorized shops in your area using this link:

Hopefully, it is not the logic board. That is a really expensive repair. The money would probably be better spent on a new phone if that is the problem.


Worst case would be both the logic board and battery. Estimate $650+

You are looking for hyptothetical answers without having the iPhone diagnosed at the shop, which will not accomplish anything.


It is either the battery or the logic board, possibly both.


Let us know what the shop finds when you take the iPhone in for service.

Batteries rarely die all of a sudden, they almost always fade slowly over a number of months.


Hopefully it is just the battery that will need replacement and not the logic board.


Good luck.

And that.....makes the logic board a possible suspect. Hopefully, it is innocent.

Would it still show battery icon if that was the case or that doesn’t mean anything? Also nothing happened to the phone that would just randomly crash ?

it sounds like the battery or logic board failed in the phone. That's not something we can diagnose from our sofa's nor likely anything you can resolve yourself. Schedule an appointment at your Apple Store Genius Bar and Apple can test the phone to determine your options/costs --> Genius Bar Reservation and Apple Support Options - Apple
