My mobile becomes too warm after using for 10 minutes?!

Hello,

Your device might get warm

When you use the device or charge the battery, the device might get warm. You might notice that your device feels warmer in these situations:

• When you set up your device the first time
• When you restore from a backup
• When apps reindex or reanalyze data, like Photos tagging for faces, places, or keywords after a software update
• When you use graphics-intensive or augmented-reality apps or features

These conditions are normal, and your device will return to a regular temperature when complete.

Here are some of the higher ambient-temperature conditions and activities that might cause the device to change performance and behavior:

• Leaving the device in a car on a hot day.
• Leaving the device in direct sunlight for an extended period of time.
• Using certain features in hot conditions or direct sunlight for an extended period of time, such as GPS tracking or navigation in a car, playing a graphics-intensive game, or using augmented-reality apps.

Keeping iPhone, iPad, and iPod touch within acceptable operating temperatures - Apple Support

Hi Gus.

I have an iPhone 6 and have recently changed the battery. I had no problems since with the phone heating up after changing the battery. Just this week it was recommended that I update the software to 11.3.1. Since then I’ve noticed my phone over heating again while indoors in an AC room. I had to remove the cover and the phone was still really warm. How do I remove the most recent ISO.

Where did you get the battery replaced? What do you mean by ISO?

If you mean downgrading iOS to an older version, that is not supported.

Sorry, I meant iOS. As for the battery, I called the Apple help line and was referred to an Apple Authorized Service Provider.

Downgrading iOS is not supported. I would suggest contacting the Apple Authorized Service Provider for more assistance.
