iPhone getting hot during normal use
Minor warmth is normal, but if your iPhone is too hot to hold comfortably, stop using it immediately and let it cool. This is caused by a runaway app, heavy processing, a failing battery, or a hardware issue.
Your iPhone generates heat when the processor and battery work hard. Some warmth during use is normal and expected. But excessive heat that makes the phone uncomfortable to hold indicates something is wrong. Either an app is consuming too much power, you're doing very heavy tasks, the battery is degrading, or there's a hardware problem.
