Just used wireless charging in my car while using Maps. Was so hot it was uncomfortable to hold. That’s the first time since I’ve had it that it happened, thought I’d dodged a bullet, but alas….

What they all miss is the rails mean absolutely nothing to the thermals of the phone, the heat was never released actively through the rails, the heat was released through the glass after it had warmed it up and then the metal was just an easy exit point once the glass was hot. The Ti does nothing here, it does not make it better or worse.


The mid frame change to have that massive center punch cut out for the Qi 2 charger is the real issue, so the chip is loading heat into the mid frame but it has less surface area for which it can conduct that thermal load, and thus becomes more localized and thus more felt as a hot spot. So had they not caved to the replace back glass effort and keeps a full size mid frame, thermals would be the same...

I bet, if I took a iPhone 14 pro logic board and put it in the 15 pro mid frame design it would exhibit the exact same failures and hot spots as the 15 pro does now even worse, I think they leaned in on the 3nm power, and heat reduction under normal duty cycles and whoops, the P cores are awake for way more things at low use than they knew for not apple tasks. So we have been carrying around the bug, for a long time now, it was just masked with a big mid frame spreader bar.


So how does apple fix this, they make the phone 2.5mm thicker, restore a full size mid frame, and boost the thermal conduction layers / heat pipe to the rails on purpose and not on accident as it is part of the mid frame
My guess is its the GPU performance increase
 
Turning out to be a rough year for Apple and then we’ve got Vision Pro next year. I honestly do think we’ll see some significant changes at executive level over the next 12 months.

And just think what all that heat is doing to your battery health.
 
Anecdotally, my wife’s 15P has been hot since she got it.
My take :
Samsung Galaxy S23 256GB va iPhone 15 Pro 512GB no external power on either both fully charged and been idle for 1 hour - testing late night. No calls no messages and no headsets or controllers connected to either.

Downloaded and installed COD on iPhone 15 Pro, signed in via Apple sign in. Started gaming and sound is just a proper full sound fun gaming. 17mins in I feel the warmth just across the volume buttons right where the A17 Pro SoC is located. Richly 30mins both the back and sides are feeling VERY warm to the touch, I’d say close to 50C where I needed to turn the iPhone around so that the camera bump is no in my right hand. Closed the game out the phone down on the ikea coffee table and in 20mins cooled down significantly back to out of box cool.

Downloaded the same COD game on AndroidOS sub-name differs but it was the exact same game. Started playing. 15mins in barely any perceptible warmth. 30mins no difference. Great sound slightly a bit tinnier (fyi both at 75% volume). An hour later, 2 hours later and I’m up to 26 kills per game!!
No heat to really speak of!

This morning my iPhone volume is set VERY LOW as usual - visually but damn super LOUD alerts! Call volume was normal but every alert was the OPPOSITE of what I set the volume slider to.

This gave me AndroidOS vibes which is confusing cause ONLY AndroidOS gives various volume levels for alerts, music and games, system alerts all separately!

WTH?!
I’m on iOS 17.0.2 updated right out of the box 3-4 days ago as it prompted before iCloud restore.

I really REALLY wanted to love this iPhone 15 Pro. I absolutely LOVE the colour. Love the look weight! Currently it’s NOT recognizing my Hyper-X SSD Time Machine backup (I’m using the same 3.2 USB-C cable it came with or my TB3 cable both which works with my former 2018 iPad Pro and iPad mini 6!). This is due tot he very low 4.5w power from the iPhone 15 Pro.

Not impressed and disappointed beyond my basic expectations. I should’ve just got the iPhone 13 mini but Rogers no longer has 512GB/256GB :(

This 15 Pro is going back tomorrow and I’ll stick to the S23 until Christmas when I can find a 13 mini in starlight. This isn’t a “PRO” device beyond photos and video and the 3nm A17 Pro SoC is NOT a Pro cpu!

I definitely think some people are mistaking the phone getting warm with “ overheating”. The minority is always the loudest in these kinds of situations.
What is an acceptable temperature? At best, high temps is energy, therefore battery life. I'm not going to bother returning mine, just yet. I feel an iOS 17 update will resolve this issue. I'm seeing more bugs than the Amazon rain forest.

I would give the S23 Ultra a try, but I've always used iPhone (since the Note 8 fiasco/recall), it's tremendously fast, and I love the Watch Ultra. I also enjoy wireless apple car-play, although they also support wireless android.

There is no leaving apple for me, if this phone blows I will return it, stay on the upgrade program and try again the next year. I can not leave them, and I refuse to leave them. Angry I am at the heat, disappointed I am, leave never
 
Reading the various threads it appears it overheats during telecon usage, that suggests overheating is a function of microwave emission during transmission and receiving of voice calls, one user in this thread stating after 35 minutes of call the phone was extremely hot
I don't think there are any fixed if this is so. Is it a function of 5G? Does it happen when using VOIP Wi-Fi only? If it does not hear up using standard Wi-Fi but does using 5G it is obviously a significant function of the 5G antenna.I don't believe there is a software fix if this is so
 
With six days of use, only one heat event with a 15P... the initial wireless transfer of data from my old phone to the new one, and after an hour, allegedly got warmer... I hadn't really noticed, but trying the camera for the first time I'm met with a warning to let the phone cool down before using. Alright. Ten minutes later it was fine.

I'm not taxing it with graphically intense processes day to day, but I guess it begs the question... what specifically could get that CPU/GPU working harder than usual outside things like video editing, maybe garageband?
it's the antenna. The data transmission in set up and transfer unleashed a lot of microwave
 
This isn't the case - at all. This has been tested with 2-5 bars of service as well as Wi-Fi calling. I really don't understand why everyone is trying to defend apple here. This issue has several reports on the forums.

You are right to be concerned.Reading the threads on initial data transfers and on voice calls there is a heating problem. This could be down to the antenna and the amount of microwave for both tasks. It would be interesting to see how it hears using Wi-Fi with mobile switched off V Mobile with Wi-Fi switched off... 5G emits much more energy than Wi-Fi or Bluetooth and I think I this is possibly the cause - Antenna Design and microwave emission when using 5G for voice calls or data transfer
 
There was one massive flaw....when Titanium superheats, it becomes like playdoh....it can bend and stretch without losing structural integrity, so oftentimes it would form small bends where fuel could leak. The SR-71 after only one or two deployments could easily lose most of its fuel by leaking and use of afterburner before and during takeoff. It would need refueling in the air and then the aircraft could accelerate and gain altitude.
The SR-71 leaked because it was designed to leak. The titanium fuselage panels, including the fuel tank segments, were loosely fitted, with gaps, to accommodate the thermal expansion of the metal once the plane reached its high operating temperature. Once hot, the gaps were filled and the plane and its tanks were tight. Had the plane been designed without the gaps, thermal expansion would have warped the plane. They could not use rubber bladders in the tanks like in conventional planes, as those could not withstand the heat. The JP-7 fuel with its high flash point temperature was specially developed for the plane. Leakage on the ground was not dangerous and deemed an acceptable trade-off. The plane would get sufficient fuel on the ground to take off and warm up, and then receive a full fuel load in the air. The fuel leakage itself was not even the issue, as it did not leak that much; the problem was air getting into the tanks, creating an explosive fume mix that would have been dangerous at higher temperatures. Once the tanks were tight, refuelling them completely would vent out any air. To prevent fume buildup later on as the fuel got consumed, the tanks were continuously refilled from nitrogen containers aboard the SR-71, ensuring they had an inert atmosphere inside.

Apple would know this....at least they should if they are truly using aerospace grade Titanium, or Ti-6AL-4V. However, that is ridiculously expensive and is used in the production of high bypass turbo-fans (commercial jet engines), wide or thin body airline structural components, military applications, etc.

It is more than likely CP-3, or Commercially Pure, Grade 3, the cheapest Titanium usage that is aerospace grade. And the Ti-5Al-2.5Sn used in the SR-71 would have a higher heat tolerance than CP-3, being an Alloy. So, the phone is heating and bending because Stainless Steel and glass absorbed the internal heat slower than the titanium does.
Ti-6AL-4V is by far the most common variant of titanium in everyday items. Watches, knife handles, golf drivers, entire bicycle frames are made of Ti-6AL-4V. It sure costs more than aluminium, but not so much to make it prohibitive for the consumer market. Besides, the titanium in the iPhones is just a millimeter thick. My little pocket knife probably has enough Ti-6AL-4V for five iPhones.

Besides, I doubt the titanium has much of a role in any overheating issues. Measurements show the iPhone 15 Pro going towards 50°C at peaks. That may be hot for a phone, but not for metals like titanium. Also, while titanium has less thermal conductivity than aluminium, it is much better than plastic or leather - so if a thin rim of thin titanium causes overheating, then phones in cases should have been overheating for years.

about time apple responded to be honest

Got no issues on mine but it's clearly more than just a few people

There are people that are doing extensive things like gaming, or Zoom calls for 1 hour or more and then complain that their phone is warm. This is pretty normal but some overreact and make claims that their phones are overheating which isn't the case.

Hi so during a rapid charge from 42 to 80 I was doing normal junk that yes may have bugs insta Reddit etc and yeah it got hot, no charge warning. Now to test a theory I kicked it up a notch to geek bench it got to hot to hold but no messages. Then I fired off the antunu bench and boom charging stopped. Let it cool and we were back to slow charging.


The question is would my 14 pro do the same and I will find out.


I can say what people are noticing is that the 15 gets warm and stays warmer longer than the 14. That’s what is getting people’s attention. Is that bad Idk I am not apple.


Over heating should be defined as I can not charge any more or just total throttling of graphics ie 120 hertz is disabled.

Uncomfortable warm is so hard to pin down. There is no message for it
 
Update #5:

Last night was playing games for ~30 mins. Didn't notice any abnormal temps. I was scrolling through Safari pages as well.

Just made a phone call- 15 mins, screen and back was very warm. Battery in the past hour dropped 10%.

It seems to me, on this $1500 phone, the phone aspect seems to be a weak spot.

Edit: A 25 minute phone call...super warm, battery went from 75% to 63%. I'm glad work has moved to MS Teams, because it would never have survived all those day-long phone calls.

I read that it may be a result of the lower heat dissipation of titanium and not the A17 Pro.


“Importantly, Apple said the issue is not related to the titanium frame. Contrary to a report this week, Apple said the iPhone 15 Pro's design does not contribute to overheating. In fact, Apple said the titanium frame and aluminum substructure provide better heat dissipation than any previous-generation Pro models with stainless steel frames.”

I guess Kuo and the others were wrong. It’s always a good thing when Apple clarifies that it’s not a hardware issue. It’s never a hardware issue. Meanwhile at Apple Park, a conversation about improving heat dissipation with the 16 Pro/Pro takes place…okay, maybe only some phones are affected?

I was thinking that I’m going to avoid all wireless charging on this device besides when I’m in the car to see if it makes a difference as I sense wireless charging is a big factor in battery degradation.

More like

1) Apple places new apps in the testing QA /QC process for both phones and software, and Craig stormed into the room and demanded answers

2) Hardware teams now got what they wanted which is some sort of cooling they have more than likely been after for some time, and will get it in the 17 not the 16 as the 16 is already done.

3) Who had to call meta and tell them to fix it or else, was it Tim, Craig, Jaws........

4) Some one in software should most assuredly be written up for missing these errors that were reported in the Beta, and not handled like the watch os location bug which, cause it is paired to a phone is dragging it down as well.

5) They do this every ding damn time you shift internal focus to the new hotness, vision pro, I knew we would see some screwed up something, we always do, I was in hopes to be wrong, sadly here we are......
 
Okay — so Apple says the heat problem is due to some rogue apps. Fine.

What’s the excuse for the heat problem when making phone calls? Is the phone app included in the report and does 17.1 fix that?

Can someone comment on this?

I was on 17.0.2 for a few days after launch (15PM) and I talked to one of my friends on FaceTime audio for 4 hours one of those days. Phone got noticeably warm multiple times during that. I updated to 17.1 PB1 the day after it was released, so Wednesday I think it was. 5 hours of FaceTime audio last night, did not notice any warmth like the first time.

Not sure about cellular calls, when I know I’m going to be on the phone a while I try to make sure I’m on FTA for quality.

I will say, between the two calls and their differing levels of warmth, battery was about the same. I remained off the charger for both of them and was using the phone on screen for the entirety of both pretty much. Hopefully this means 17.1 is a step in the right direction.

This is what I figure will happen, they will try to fix it in a dot.0 release on the path to .1 and fold it in.
