Iphone 16 battery drains super fast and overheats

So i've been using my iphone 16 since october 2024 and I have 71 cycles with it. I bought it brand new and in settings it says that the battery health is at 100%. Two days ago I used some sketchy looking wireless charger and after using it my phone started overheating and battery draining surprisingly fast. I tracked how long it took for it to drain 10% whilst doing usual stuff like writing messages, looking at videos n such and it only took 23 minutes. Idk it may be normal but I don't think so. Any help?

iPhone 16, iOS 18

So, where was this sketchy charger? Public charging stations are a well known way to compromise your iPhone with Malware and worse. There really needs to be more background information to properly diagnose this issue.

Ah, OK, that changes many slants to to this issue.

Wireless charging is a very inefficient way of charging a device and can lead to excess heat at times. This is especially true if the iPhone and/or case don’t line up precisely with the Qi charger. iPhone 16’s also support Qi 2 charging and it’s a fast charger, basically charging at twice the speed. Twice the speed equals twice the heat.

The draining issue is possibly unrelated. Can you provide more details?

What apps are you using that is draining your iPhone so much?

Let’s look at the apps that are using your daily battery capacity. Please post a screenshot of your battery usage for last 24 hours. Please follow this path,

iPhone > Settings > Battery > scroll down slightly and screenshot of graphs and apps

Here mine,

like what? I don't have background refresh turned on, my Iphone doesn't have any cracks or physical damage, during these few months i haven't dropped my phone in such manner that it could have generated internal damage. Like what are you referring to when you say "more details"?

Over 60% of your battery are being consumed by non Apple software. When was the last time you updated the third party software? Instagram has been updated multiple times in the last month trying to fix their bugs.

Why is your skiing tracker running in the background tracking your location and doing background activity?

You have multiple 3rd party apps we need to explore. First step is making sure all the apps are updated to their latest versions.

ok I think I fixed it, I let my phone completely drain then left it alone for an hour just like i would have done for a battery recalibration and I think it's fine now? It hasn't overheated and I tracked how long it took for 1% to drain and it took around 10 minutes. I'll let it charge for a few hours then tomorrow I'll come back with an update.

Hi please give us update on your battery recalibration

I had my 15promax brand-new Last Nov 2024

And I'm sad because the battery capacity is at 99% and now it's overheating also and drain to 1% every 3-4mins😥

I never over used it I had my other phone to do such gaming and watch movie

It all happened when I update to ios18 from ios17 when I got it as brand-new.

I search and follow all the tips for the battery health care. Hope I find a solution to fix this.

so I've done a battery recalibration and half of the problem seems to be fixed. It took me almost an hour for the first 10% of the battery to drain which I guess is normal but the overheating problem is still persistent. Idk what to do about that. I'll try some other things and will come with an update.

I've also solved the overheating problem. It was caused by the esim I was using.Whilst using my regular sim I noticed that the phone was not overheating at all but after reactivating my esim it started heating up like crazy once again. So in conclusion if you have the US version you gotta live with overheating and battery problems.
