I have a theory about this.
Inductive charging is incredibly inefficient and generates a lot of excess heat (waste). Heat accelerates the death of electronics. And inductive charging coils are paper thin.
I suspect that 24/7 charging generates enough continuous heat that it degrades the coils over time.
Now I have a couple Touchpads that get this kind of use -- one is a digital picture frame about 90% of the day (except when I'm reading the morning news) and the other is now a permanently alarm clock. But I've employed a couple mitigations that I'm comparing...
- Picture frame Touchpad is on a "smart outlet" that turn on in the morning, off during the work day, on again the evening, and off again at night. The Touchpad gets about 6 hours of charging a day, and always has a happy battery, but it reduces total time on a warm coil.
- Alarm clock Touchpad is connected to a USB charger that is a little less power than it would prefer: 1.8amps instead of 2.0 from the OEM adapter. It seems to run cooler as a result -- the Touchpad complains once per boot, but is otherwise fine with it.
Of course, I don't know if these ideas help. And besides, these are old pieces of equipment and if they spend their last years or months in a way that makes you happy, I say run them til they drop. But if you want to eke out a little more time, consider reducing the total time spent warm some how.
