And in the early years it did this. Eventually Google updates seem to have made it better BUT when the battery gets too low it does seem to have trouble getting charged up and booting.

Lesson? I rarely take it off the charger now and when I'm done, back it goes.

Now I didn't read if you had other cables and chargers. So try those. If no go then watch a YouTube on opening it up to unplug the battery for a minute. I am NOT advising this but some report it helped.
