I also have a Nexus 7, but it's now slow as molasses to the point of being unusable. Maybe I should try a factory reset...

I think someone mentioned there's a new kernel and lineage build for it, but it might just be time to admit its too old. I used it as a pdf reader for a while but its been a couple years since I last tried to use it.

Try replacing the battery. The Nexus 7 was way ahead of its time.
