iPhone 15 Pro Max stops charging at 80%

Hi. I’ve had this issue! Apple even sent me out a new phone and the issue still persisted.

The last two nights I have gone back to USB- type C charged and it has since charged to 100%.

I think the 20w fast charger that is supplied with the new phones is charging up the phones too much which caused it to heat up and stopped charging at 80%

Multiple Apple stores nor a customer service provider could figure this fault out, I’ve had to figure this out myself.

Hi, happened to me also with my iphone 15 pro. Pls try another adapter, solved my problem with this.

I believe the 80% topping out limit is new, you are correct in saying the optimised charging has been there for some time but that charged past 80% once it learnt from your charging patterns.

the new limit doesn’t charge up to 100% if activated. It’s one of 3 options now available

Hi, happened to me also but when i used another adapter (new adapter) the problem disappeared 😊 hope it helps

I had the same problem with my iPhone 15 pro max. It was driving me mad. I changed the charging block and it worked fine. Hopefully it’ll sort the problem for you too.

Had tried 2 options and it charged past 80%:

-unplug when it reaches 80% and plug again to resume charging to 100%

-charging using the provided usb-c cable to a laptop

i'd like to know for those guys who said to use a new charger. did you guys use a brand new charger by Apple or a third party trusted brands like Aukey, Anker, U-Green etc? currently im using the 20W Model A2305 of Apple that I've been using for over 2 years. And I don't want to buy the same type of charger esp if it's the same model number cause what assurance do I have that it won't perform the way my present charger does. This is my dilemma.

I have iPhone 15 pro max, charging it stops at 80% I got the type c cord and 30 watt plug still same. 80% stops charging in setting for battery if Chang to 100% works but Apple told me that that will cut back life on battery but want it charged to 100% last longer when I’m on phone !

FYI, it's not new. It was added in iOS 13.

I want to know ,is there any problem if i change my phone 100%?

I'm late to this convo...but while there's not a "problem" if you charge to 100%, it will likely decrease your battery life.

For me, as soon as they gave the option to limit to 80%, I turned the feature ON and love it. Now, I can charge as often as I want, and my "maximum capacity" (in Battery > Battery Health) is still 100% while my wife's has gotten lower. So, I'm surprised anyone is turning that feature off...my phone can usually last 2 days on a charge even after only charging to 80%...so I'm happy to let my battery live longer.

After two years of constant charging, I'm betting my 80% charged will last longer than many people's 100% charge.

same issue with mine, i had to unplug and plug again to continue charging, has your charging continue reach 100% now even set to NONE? whats the update?

I have had 15pro for 1 month and experience the same 80%. Called Apple and was told "no problem with the Battery" then why only 80 %? I ..have changed settings not different. My iPhone XR works better than the phone.
