Compared to the battery degradation I have experienced on my cheapo android phones over the years it has done very well. It doesn't get much use though. It's the best "player of appstore bullshit" in the house but it collects dust for periods of time. Last time I used it regularly I was playing a port of Planescape: Torment. If I ran a business it would be half of my point of sale terminal and I would thank heavens I had it but the thing is otherwise a big expensive time waster. Its main function could definitely be to keep up with the Johnsons.
