  • You can use a battery powered device without the battery plugged in. I’ve never built capacitor bank for a more modern mobile device but its probably possible with off the shelf boards. The last one I built was years ago for a dentist office. It was a mp3 player they used for the hold music. Pulled the bad battery and built a fairly small capacitor bank. The only complication was getting the right resister for the third terminal. In the case of the mp3 player it was a temperature sensor. Modern phones use this channel to communicate battery info which might complicate things a bit.

    I had a computer shop in the early 2000’s. A guy comes in and asks about some computers at a closed doctors office. He asks what they are worth and I told him I had no idea. I agree to meet him at the address and when we walk in its pure 80’s in there. The newest computer was a 486. The doctor died suddenly and they just locked the doors. No one had been in there for over a decade. When I was looking around we found some bananas just like that. The use by date on everything was 1993 or so. Needless to say I told him to junk the computers.
