Heating
Is it normal for the screen to be getting a little warm after playing a couple games on it
Question marked as
Your iPhone will get warm as it charges. It may even get hot at times depending on ambient conditions and the level of charge applied. All this is normal. If your iPhone gets too hot to operate, then it will shut down as a safety precaution. If it has not shut down then it is not overheating and operating / charging normally.
If your iPhone gets too hot to touch, often, then you can have it examined at the Apple Store or at an Authorized Service Center and take advantage of the 1YR Limited Warranty from Apple.
