iPhone 16 Pro overheating and Battery Drain

Something’s not right with the 16.

I agree, something is wrong with your phone. Have you tried restarting the phone?

Beyond that contact Apple support.

The phone is 3 months old 16 Pro and always up to date, Apple replaced the phone after 3 weeks and still the problems occur.

60% drop in battery and no texts, some emails received simply not good enough.

I ended up turning the phone off to cool it down, restarted it and it heated up again immediately - this is not normal, I've had Mac products since 1990 and this is simply the worst product I've ever had from Apple.

I charged this phone to 75% and then not used it for 5 hours, now stinking hot and 15% battery left!

I hate this phone

The solutions were already posted over a month ago in the thread you just added to, so please review it and post back if doesn’t answer.

I’m also experiencing the same issue, my phone gets warm and the battery drains very quickly. I’ve noticed that others have mentioned this problem, but I still haven’t found a solution. @dpietrowski2, do you happen to have a large photo library? It might be due to indexing, I guess.

Lawrence thanks your response makes sense, however, I don't trust charging overnight with a really hot Lithium battery as they are prone to explode and start fires, I don't fancy that while I'm asleep.

I will try the Restore option.

Great, glad to hear of your success. I know that this happens to a few phones, but it is actually quite rare. But your suggestion that it should be a support knowledge base article is really a good one - why don't you suggest it to Apple→Product Feedback - Apple

I’ve never seen any reports, except in the case of a battery being physically damaged, so I did a web search for iPhone fires and found only one report of an iPhone 4 that was 14 years old. And it was plugged in to a charger that in turn was plugged in to a newly installed electrical outlet. I found a number of articles saying it can happen rarely, but no other actual reports.

All of the articles I found said the chance is around one in a billion, which I don’t believe because it would mean it had only happened to one iPhone in all of iPhone history, but can believe one in a million.

It’s also well documented that counterfeit and low quality chargers and cables can kill iPhones - Why Counterfeit Lightning Cables Kill iPhones - Motherboard

2 video teardowns of cheap power sources:

Apple iPod chargers - fake versus genuine - YouTube

2 counterfeit iPhone adapter video

As I’m sure you only use quality accessories there is no real risk to you.

I have a new I phone 16 plus one week old. The battery drains very quickly even if I don’t use it. Please help

Define “very quickly”. If you charge the phone overnight, every night (a best practice), it should not need to be charged until the next night. If it achieves this goal it is not draining very quickly.

Am also experiencing same issue overheating and battery finish fast

And define “fast”. If you charge the phone overnight, every night, and you don’t need to charge it until the next night that is not fast, that is normal.

Lawerence I think you’re just blatantly wrong about this issue. Every response you have makes no sense. I still have pretty unusual battery drain that is atypical of any other iPhone I have had. My phone still get warmer than it should based off all iPhones I’ve had before. Your responses are vague and don’t help anyone with their issues. I would suggest not commenting.

As it is my field of engineering, I am not wrong. But if you can’t accept that then we have nothing further to say to each other.

Yesterday no apps opened - too hot to open and battery draining quickly.

this has been since new.

Apple when are you going to fix this issue?

A quick update, phone has been on charge for 6 hours and is now at 62% and really hot!
