iPhone 13 mini overheating

[KEIN NEIN]

I have a used iPhone 13 mini (256GB model) that I bought like 6–7 months ago, and it's been a while since it gets uncomfortably hot, especially when watching videos for too long or installing updates.  

 

It bothers me so much that I place a table fan next to it when charging. I turn off Bluetooth and Location, and never use it while charging.

 

Also, I am worried that it might shorten its battery, as it's already gone from 100% when I bought it to 93%. I am running the latest version of iOS and use the original 20 W adapter for charging (the cable isn't original though).

 

My questions are: ¿Is it normal? And: ¿How can I prevent it from heating? Thanks.

I don't think that's normal. Is the phone still under warranty? If so, I'd contact apple as to me, it sounds like it's defective. Is there a thick case on it?

 

Another thing, what kind of charger do you have? Is it just a cheapo store brand, or is it from a reputable brand? I'd try switching to something from the likes of Anker or any established company, as those cheap ones are cheap for a reason, and can cause issues like this (usually only when charging though).

It doesn't sound like it's a normal thing. What I would suggest is to perhaps go and have an apple store run a diagnostic. Issues like these are speculation at the most however from what I know, my wife uses her iPhone 13 mini intensively at times but it's thus far has managed to keep it's cool rather well. It's about the same age as yours so yeah. Initially, I'd perhaps recommend to try and not use the device when charging(even though most of us are guilty) and to yes, as mentioned by @Dillpickle23422 to check your charging brick. Though phones have grown more adept at charging usages, it's still a strain on the battery regardless..

Thanks for the quick response.

I use the original 20w usb-c adapter that you can buy from Apple. But the usb-c to lightning cable isn’t original

 

As for the case, I don’t use any case. And Apple coverage expired sadly

I wish there were an Apple Store nearby. There are only two in the whole country and both are located in the capital.

Excuse me, what do you mean?

 

I never let my phone go below 20% and usually charge to 80-90% with the OEM charger.

No problem with the quick response. As you mentioned with the location and bluetooth, does disabling this stop the phone from getting really hot, or is it just an effort to consume less power? If it gets really hot when charging, I would think that there's probably an issue with either the battery, or charging IC/connector/anything else related to battery management and charging.

 

I'd see if a local store can diagnose the phone (if there's any nearby)

First thing I'd look at replacing is the battery, as you have issues with battery health, plus it's getting really hot when under load and charging. Seems odd to me that such a new phone could have battery issues this early on in it's life, but maybe it's just a defective battery that slipped through QC.

I do it bc I suppose it causes less heat, but even with bluetooth and location services disabled, and even if  never use it when charging, it overheats.

 

Indeed, it feels warm as I am typing this.

Interesting. Like I said, I would first suspect the battery. As they discharge, they obviously get a little hot. Under very few circumstances should they ever get hot to the point that it's uncomfortable to use the phone. The battery is the easiest culprit here. However, I would either call apple support and explain your situation (they do mail in service, if absolutely necessary) or take it to a local shop that knows a thing or two about diagnostics.

OK, I’ll try that out, thanks

Perhaps try and phone apple support. Sure, it's tedious going through the procedure of phoning them but if you were to explain to them your issue they might perhaps answer your question with some advice and/or suggestios. Compared to other manufacturers, their support is quite good and more accurate.

Yeah! No problem! Let me know what they have to say, I'm interested to hear what they tell you lol

I bet this is 100% caused by software.  Try using Firefox instead of Google Chrome.  Turn on power saving 100% of the time, and enable the batery aging setting which limits charging above 80%.

 

Go into the search (iOS, not chrome or safari search) settings and disable everything you do not use.

 

Turn off background app refresh.

 

Disable app usage collection and the "learn from this app" whatever that does.  Turn off iCloud when away from home wifi, and turn off cellular unless you are going to use music streaming or web browsing, and turn it off when done.  As much work as apple does to reduce tracking from apps, I bet all their stuff constantly uploads data, all day long, if you leave any connection on, so turn off both wifi and cellular unless you have a program open, waiting to connect.

 

If you are not wanting to try open-source Firefox which has been around since 1996, try using Safari, which also has roots in open-source software, called WebKit.
