I feel like my iPad Pro 12.9 is heating up on the left edge
My iPad Pro 12.9 M1 heats up the left edge of the screen just having the screen on is not an excessive temperature but I am worried that it has an elevated temperature performing tasks that require little system resources. I hope you can help me if it is a specific problem or is it normal?
When being used, the iPad or individual areas of the iPad may become warm - this being entirely normal and as expected. However, the iPad or localised areas of the casing should not become uncomfortably hot - as this may be an indication of malfunction.
If you have any concerns, you would be best advised to visit the Genius Bar at your local Apple Store - where the technicians will be able to examine and test your iPad. If anything is untoward, or repair is required, you’ll be in the best place to have the problem resolved.
