My ipad 5th generation will either freeze and not respond or will turn itself off. Any idea how to fix?

If iPad isn’t responding, do one of the following:

• 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 iPad still doesn’t turn on, or if it gets stuck during start up, see the Apple Support article If your iPhone, iPad, or iPod touch won’t turn on or is frozen.

I am going to have you tap on the link below to my iDevice/iOS performance/optimisation user tips link and try all of these.

Slow iPad on iOS 11, 12, and iPadOS - Apple Community

Try all of these tips and leave each tip active together.

Do not simply try every tip individually, expecting just one tip to be a performance “cure all”.

Many of these tips are designed to work together to help improve overall iOS/iDevice performance.

Good Luck to You!
