However, I wouldn't worry much about battery life in your device. The

I'm currently using a Nokia cell phone that is nearly 15 years old.
Miraculously the battery is still working OK, thought it may not
be quite as old as the device itself is.

Using a 10-year old Nokia here. Original battery.
Granted, I don't use it like some air-head teenager....
