Slow wireless charging after iOS 15 update

Hello living_teal,

Thanks for using the Apple Support Communities. We understand that you're running into some issue with wirelessly charging your iPhone. Would you mind letting us know which model iPhone you're using? Have you tested to see if this issue persists if you charge your iPhone with a cable instead? When you say it doesn't follow charge overnight, is there any chance it's stopping the charge at 80%?

Best regards.

Qi charging works again!

Not sure if this was introduced in iOS 15, but switching off "Optimized Battery Charging" did the trick for me.

Settings > Battery > Battery Health > Optimized Battery Charging

iPhone 11 Pro

iOS 15.0.2

I found myself searching for this on Google and here i am. Since the iOS 15 my phone has been charging ultra slow. I have a iPhone 11 Pro Max. Basically what happens is my phone charges normally, for about an hour and a half from 1% to 90%. But from 90% to 100% it takes roughly an hour for each percent. At first i thought it was some kind of visual bug and i restarted my phone several times but nothing. It literally takes an hour to increase the percentage with 1 step.

On the contrary, ever since the update, my battery has reached new heights. With minimal usage - just phone calls and Spotify in the background - my battery lasts between 12 and 15 hours on 100%, i kid you not. But as soon as i start using some apps like YouTube and Myfitnesspal, it suddenly drops to about 90% after an hour of usage.

So love it or hate it, this update was good.

P.S. Glad its not a hardware issue, probably its some software bug that will be fixed in the next update.

Hi living_teal,

Thanks for the follow up. Do you have another device you can test your MagSafe charge with? This can help determine if the issue is the charger or your iPhone. Also, do you happen to have a case on your iPhone? If so, do you find the same issue occurs when it's removed?

Best wishes.

Missy5937,

Having the same issue.

iPhone 12 Pro, Magsafe Charger, Leather Magsafe Case - in case that could be causing higher heat resulting in slow charging?

Updated to iOS 15 on 9/21.

Night of 9/21 to 9/22 - stopped charging at 80%. Checked the energy graph and I could see it reach 80%, then fall slightly and then increase again, etc. So optimized charging stopped it, but for no reason. No change to my routine or anything. It is usually charged to 100% by the time my alarm goes off (set on my phone) for 5AM M-F.

Night of 9/22 to 9/23 - did not even charge past 68%. Checked the energy graph and it slowly charged all night to 68%.

Night of 9/23 to 9/24 - I turned off optimized charging since I need my phone to charge to 100%... Hoping just turning it off and back on a few days later will help correct it. As for slow wireless charging, I am not sure if it will continue.

My phone and Apple charging cord were fine before the update. It’s not the cord or debris or anything other than an Apple related issue. It needs to be fixed. Suggesting I put my phone on airplane mode is ludicrous, as well as, a huge inconvenience. Shame on Apple for blaming the victim for their incompetence.

Hi, I use an IPhone 11 Pro and ever since I downloaded IOS 15, charging my phone takes forever! It has been more than 6 hours now and my phone hasn’t charged fully and keeps decreasing and increasing in charge! I’m using the original charger that came with the phone and had no issues at all! Could you please look into resolving this issue asap issue.

Also having problems with 2 x XRs and 2 x 13s

Prior to buying the 2 x 13s, my XRs all reliably charged on 4 different types of wireless pads. When we went iOS 15, all 4 phones have unreliable connection to some of the charging pads, resulting in little to no charging taking place on those.

Noticed it's a bit better outside of the cases, but those cases were reliable before for charging.

I have an iPhone 11 Pro Max, I use different models of Anker's wifi chargers. I suffer the same behaviour after the latest update, the phone didn't charge over night in the bed charger (Anker Wireless Charger, PowerWave Pad Qi-Certified 10W), now i'm using the Anker Wireless Charger PowerWave Stand and it's charging very slowly. A few hours and it's only on 67%.

I have an iPhone 11 Pro Max and a company iPhone SE both now on latest version of iOS 15 and now both phones not wirelessly charging properly. Have multiple wireless chargers and not working on any. Works fine when plugged into a charging lead.

13 Pro Max, since last update, the 15.02 or whatever that came because of vulnerability, wireless charging completely gone. Using Apple store bought charger. Same on 11 pro max and X pro max, all on same upgrade, not working on any device anymore.

Hi,

I have a brand new iPhone 13 pro and since I upgraded to iOS 15.0.1, wireless charging does not work on any of my wireless charges where it previously worked ok.

my wife’s iPhone 12 still works on them but she hasn’t gone to iOS 15 yet.

it seems there’s an issue with iOS 15 to me as rebooting doesn’t fix it.

could someone from Apple reassure us that we’ll get a rapid fix please.

Same problem - very odd charging behavior (very sensitive to position, and no matter what no full charge anymore overnight).

Anyone know what the problem is? I use a no name brand charger, but until right around the last update everything was normal, in fact, my XSmax would charge fully in about 2 h. No more....
