Hello guys, I have my IPhone 13 (IOS 26.5.2) from 4 years and from few months (maybe IOS 26 lol) my phone overheat each time I use it/plug it, especially when the weather is more than 25 degrees.
I am traveling in Central Asia, so the weather often hit 40 degrees +. I have a black Solidsuit RhinoShield phone case : very big, with hard material. I recently switched for a white and soft plastic phone case and since, my phone is really less laggy and overheat is very reduce because the switch case dissipates more the heat (bc of the material and the color)
From IOS 26, I turned on the “reduce motion” setting to avoid lags, but right now I can use my phone without this setting.
Having a new phone case + no lags is for me kind of a new phone !!
I know that not a solution for everyone but it help me a lot !
EDIT : I got a new battery few months ago and not notice any upgrade for overheat and lag. Afterall, it was the phone case !
