iPhone 15 keeps coming on and off charge

I just got my 15 and i’ve been charging it with the cable from the box and an apple usb c plug, every time it goes up by 1-2% it comes off charge then goes back on again. I’ve tried it with another usb c apple cable and has the same issue, charged it with an anker cable in my car with the same issue and I’m at a loss now of what to do!


I’ve always had the old cable issue of wiggling it to the right angle to charge but this isn’t the same thing, it can be laid flat and still go on and off charge like no tomorrow! It’s on IOS 17.0.2.


It still does charge and hold charge it’s just annoying and a bit concerning that it keeps going on and off like it is


EDIT: not sure why it says i posted this on my 12, i have posted it on the 15 🤦🏻‍♀️

Do you have charging optimization on in settings? If it’s set to 80% limit and your phone is close to 80% when you plug it up that may be the issue. Same may be true if you selected the Optimized Battery Charging option. Switch it to None and see if the same thing occurs. If it does then definitely take the phone to your nearest Apple Store to be evaluated (or call Apple for assistance if you don’t have a store in your area). You are still in the exchange period so you could also just opt to exchange it.


And it’s not saying you posted from your 12. That’s just the device you have on your profile.

Update,

For some reason with another brand new 20w power adapter it doesn't behave like this. No more repeating notifications. I already tried before a new adapter exactly the same as this. Only difference between them is that one is from an Apple Premium Reseller (charger with the paper foil on it). The other one is from another electronics shop. Don’t get me wrong, both are supposed to be produced by apple. Same identical box, same inscriptions. I don’t know what’s causing this.

it doesn’t make any sense.

After charging it once with the new adapter, the old adapter was also working fine.

I suspect there is some kind of machine learning/NLP trying to learn and adapt the charging power that fails sometimes and results into these power interruptions and charging notifications.


Try a few other new chargers until

it works and blame apple.

I just got my 15 plus and have been using the 20w adapter and the cable that comes in the box with the phone and I still have this issue. I tried turning off charging optimization and it’s still happening. It charges normally on my wireless charging pad as well as when plugged into the usb in my car, I’m only having the issue with the charger provided by apple in the box. Hopefully they can make a fix for this I’ve never had this kind of problem before
