Accessing a dead iPad (4th Gen)

Anyone have tips on getting a dead (4th Gen) iPad running?

Apparently the battery has been on its way out for quite some time, taking a very long time to charge (a few hours for only a small %).

It refused to charge at all a few days ago. I have tried multiple cables, including brand new
Apple ones. It will not turn on.

I plan to charge for a full 12+ hours to see if you will spark to life, even if momentarily. I am trying to get some information off of it.

Any other suggestions?

Check for lint in connector…

Maybe try plugging into computer so if it does spark up, you can quickly back up…

When (if ever) was the last time it was backed up? While not ideal, maybe a 6 month old backup has most of the data you’re trying to retrieve.
