I recently found my old e-reader (Kindle Keyboard) from 2011 and the first thing I had to do was swap a new battery in, the old one would not hold a charge for too long.
I haven’t played with it long enough, need to check again.
I’m also happy and surprised that all my music files are there and that everything works. I haven’t touched it in probably 4+ years, and was under the impression that flash memory, especially older generation like 2010, can degrade / bitrot if it’s not powered every so often.
