My iPhone 15 Pro Max heats up when charging

I get so annoyed and frustrated on this iphone 15 pro max. The battery drains so fast, literally used up 80% within 4 hours and the phone gets so hot when charging. i turned off whatever that was suggested yet nothing helped. Soooooo disappointed and have nowhere to get help.

I understand that logic. The simple truth is , It’s very simple, The fact that my iPhone 12 Pro did not overheat whatsoever and now all of a sudden the 15 pro overheats. Sorry, gets piping hot is NOT normal period. I’ve had eight iPhones and have 13 Apple products. In fact, did a test with my dad’s iPhone 15 and is as cool as a cucumber. This may be a 15 pro issue.

No excuse, hot is hot, This is the truth.

Don't educate me to accept that "Hot is normal". But this is extremely hot.

Do you want me to say " it is not hot, a very high advanced phone" . No way.....

Unless you guys have a good solution to fix this big problem.

It is perfectly normal on all phones. It’s called the Second Law of Thermodynamics. Anything that creates or uses energy does so with some loss. That lost energy is expressed as heat. So when you charge the phone it generates heat in the power source, heat in the charger circuit in the phone, and heat as the energy goes into the battery. The faster the charging, the more heat is generated. Likewise when you discharge the battery; not all of the energy from the battery gets to the circuits that use it. Some of it becomes heat. 

If you use the cellular network for voice or data, converting energy to radio frequency signals is very wasteful; only about 30% of the energy that goes into the network components comes out as radio signals, the other 70% becomes heat. And signal strength matters; a 1 bar signal requires that the phone boost its transmitter power to maintain a connection, and it isn’t linear. 1 bar uses 10 times as much energy as 4 bars. You didn’t mention your phone model, but an iPhone 12 or newer (including SE 3rd edition) with a 5G signal uses about twice as much energy as an LTE signal, and 5G towers are still not as densely distributed as LTE, so the signal is likely to be weaker, compounding the problem.

i have 15 pro and i have the same issue. it gets extremely hot while charging and it starts to cool down after it has reached 80% charge. but before that, it stays hot. i even charge it without its case on and i use apple charger and given cable only. This is a genuine problem with no given solution.

Apple had the audacity to call me back after an hour and a half of discussing to tell me that this was normal. (obviously did not accept that answer and had them schedule me to have it checked out at Apple Store) I have a brand new one day old from December 7 iPhone 15 Pro 256 GB. (On iOS 17.1.2) Phone gets piping hot when plugged into Apple OEM cable charger. Seems to be fine with wireless charge. Prior phone was iPhone 12 Pro 256 GB. No issues. Lawrence, what a kick the can down the road kind of answer to blame everything on everything. Why was everything good with my 12 Pro and now the 15 Pro immediately overheats. This is bad.

Why do you try to use physics and things to show people that is common sense and no-brainer when literally physics and things you just said are not common sense and don’t really play any effect here. Don’t use those terms to say people are dumb.

(Apologies for such a long drawn out comment) I’ve been in wireless sales/repairs for 20yrs maybe I can inform on the topic. You’re not alone this happens to my iPhone 15 Pro ALL THE TIME whenever it’s charging & I’m using it to play a game, play music, browse online, etc. without fail after 30-45mins at most I’ll get the pop up saying “Charging will resume when iPhone returns to normal temperature. I do have some “informative” input. It IS an iPhone 15 Pro/Pro Max issue. I’ve been in wireless retail since ‘04 after graduating HS. I got a job at a Nextel(hands down BEST carrier & features EVER! Especially the direct connect) My store was a retail & service repair center. So the past 20yrs have taught me a TON about wireless especially being a certified wireless repair tech I’m also certified by Apple to do service & repair. I’ve been with my current store now going on 4yrs. I’m a Retail Store Manager at a VZW store. Granted not corporate Verizon but w/the biggest Verizon franchise in The US(Wireless Zone) so I’m not but 1 step below corporate stores & customer care far as what we can and cannot do in my store & the only sole difference is we absolutely cannot adjust/credit a customer’s account. This is a very well known issue to Apple according to my stores Apple Representative however for whatever reason they’ve been unable to pinpoint the bug bc normally a software update would fix all across the board. However in this case that will not work, clearly if we’re still experiencing it since the base iPhone 15/15+ don’t have the issue so it’s something in 15 Pro/Pro Max boards or software. So who knows honestly when it’ll be fixed. My Apple Rep seems to believe that while it’s a huge inconvenience to users it doesn’t rank high enough on list versus other known issues therefore it’ll probably be a long time if ever.

Yes I can, and do. You can disagree, but you cannot prevent me from stating facts.

That’s exactly right my iPhone 14 and 13 Pro Max never heat up. They only get slightly warm when I charge it and don’t use it the iPhone 15 Pro Max I have now he’s like a pan.

Original Apple cables and 20 watt charger for every scenario. iPhone 12 Pro, iPhone 15 and the 15 pro. Only one with issue is the 15 pro as mentioned.

If it doesn’t turn off to cool down it is not overheating. And the fact that when you charge it with a 7.5 watt Qi charger it will not get as hot as with a 20 watt fast charger that proves it. That’s simple physics.

Me too , switch all the APP ,WIFI , Data , still super hot. i am very sad from the day 1 i have this iPhone 15 pro max. within 7 days, the shop studio don't accept return or change.. i spent 2000SGD plus , i hate this super hot apple phone. i went to Apple customer service, their technical said, " hot is normal, mine is same as yours".

How to do ? i went to the studio shop and apple service center at orchard road, Wasted my time and energy, nobody can help........

You seem to be a smart person but right now you’re being a troll. So as the old adage goes, if you have nothing nice to say then it’s best to say nothing at all. You’re really not providing anything further to this forum. You’ve given your explanation of it. What it comes down to is that it’s not something unheard of, it’s an actual issue, and there’s a flaw if it’s so inefficiently charging and it’s only with the 15 Pro. So please, if you don’t have a solution don’t frazzle the rest of us further to try and play up your intelligence because you’re making yourself out to be a smart *** not smart.

No, you cannot use that to tell people it’s normal my 15 promax is a replacement after I got a new one and I charge it Without using it at all.

my iPhone 14 Pro and 13 Pro Max never heat up when I charge them. That law is correct but it shouldn’t hit up the phone. The phones can slightly get warm while charging when you don’t use it.
