Hot, Gradient Screen, and Battery does not stay charged long

Perform a forced-restart of the iPad - as doing so will often resolve an isolated software or overheating issue:

• On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.

If the problem is unresolved, you might be best advised to seek assistance directly from Apple Support. You can contact the Support Team using the Get Support link at top-right of this page. Alternatively, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess the iPad:

Be aware that sustained elevated temperatures may have caused damage to the iPad battery.

Within reach I have two iPad Pro 10.5 WiFi+Cellular 512GB. Both continue to operate - both with a known issue concerning screen diffuser delamination and deteriorating batteries. Otherwise, both are fully functional - and neither exhibit the issue that you describe.

As such, given that you have followed standard troubleshooting without improvement, you may just be unlucky and have an iPad with a hardware fault.

Is it worth spending money upon what is likely to be an out-of-warranty exchange - the cost of which will likely amount to Apple’s standard fee (c.60% of the as new cost of the iPad)? For me, I would instead invest the cash in a replacement iPad Pro.
