iPhone 15 charging keeps blinking and beeping

I have this when my phone (15 Pro) is plugged into my car to charge…. Is it a faulty phone????

Still no resolution? This is so annoying especially when you’re sleeping

I had same issue with my 15pro. Tried a "anker" cable first. Thought it was a pattern with certain numbers since it was happening at 2,4,6 & 10s of numbers when going up, cable is a little loose in the porrt as well! I texted apple they thought my mag safe case was triggering it. Took the case off & switched to cable that came with the phone & it was still doing it. The phone takes a charge but the flashing/buzzing is annoying.. cant tell if it's a port, cable, or system defect!

I JUST purchased my iPhone 15+ this morning and had no problems charging with a traditional USB-C charging cable in my vehicle and in my house. As soon as I try to use the C-C cable provided with the phone there were glitches and blinking lightning bolt symbols in the battery area. I tried powering down my device, switching sides of the c-c cable, block switches etc. and NOTHING helped. Seemed to take the charge away faster actually. But the only solution I’ve found thus far is using an off brand USB -C cable with my Apple device. Still hasn’t charged up from 10% but praying it works 

Hey @jordana128 so I’ve figured it’s to do with the Wattages and not the cable. I got the same 1% blinks/vibrations when charged using a plug/Anker charger above 20W. If use anything below 20W am able to get a smooth charging. Includes both OEM cable that came along with the phone + anker 2m cable that I use.

I had this issue and after trying 4 different charging cables and sources (two different adapters and cords in my house, a third cord in my car, and a fourth cord at my office plugged directly into my Apple laptop) I can confidently say that, for me, the cords were fine. The issue was the optimized charging and the clean energy options. I just turned them both off, restarted my iPhone 15, and now my phone is charging correctly.

I am guessing that, for me, the most recent update did something to cause this.

This did not work for me. Even if turning off optimization fixed the issue. Ultimately, you will have more wear and tear on your battery requiring you to replace your phone much sooner. This does not sound like a solution.

As someone else mentioned here , I have an iPhone 15 and it seemed to start for me with iOS 17.3 update - this happens with my in-car charger cigarette charger, which is a certified as USB-C PD port (20W) and a Belkin USB-C to USB-C - both bought in last month as I thought it was my old in-car charger that I’d had for 3 ish years that was the problem!!

this doesn’t seem to happen on my in-house charger I use a night (thank heavens)- where I use a Juice mains USB-C 20W PD charger and the supplied Apple USB-C cable.

this issue is very annoying - not found a fix yet, but notiys me every 2 seconds that my phone is charging via the Dynamic Island notification.

please, please a fix soon….

I used a normal usb to type c cable for charging my iPhone 15 max pro and it’s working perfectly with no blinking and beeping. The problem is with the type c to type c cable and box.

Iphone 15 Pro blinks, beeps, and will not charge when at, or below 3%.

Using the same cable, block, etc… when the phone is at, or above 10%, it charges just fine.

So my solution is not let it drop low

Ok it’s been doing this for me too one thing iv been doing is getting a white noise app on my phone at night (if you don’t like the noise turn it down) but it really helps to keep the noise of it going off quiet!

I have a 15 pro max. Same problem. I bought a very nice high quality charger, actually 2. One for the car one for wall plug. Each has a usb-a and a usb-c port. High quality. From Amazon the brand is "Fast." Came with 2 high quality usb-c to usb-c cables. They worked fine until recently. Maybe my last software update. Both chargers work fine with a cheap usb-c to usb-a cable. It's got to be this 17.3.1 update.

I have this problem on my USB-A/USB-C 20w combo block and it keeps charging then not and keeps going till I unplug it. It charges off my pc USB-C port and also on my power strip USB-C didn’t make any sense

Same problem here; I changed my non-Apple certified plug for another, identical plug and voila! no more beeping Every. ******. Time. it gained another 1% in its charge. The plug (which also had a cable for my iPad) was really hot when I swapped it out, FWIW.
