It was a fun project - but I wouldn't use old cellphones. Having these old cellphones plugged in all day - basically just made the batteries enlarge and broke the casing. But you can get old android phones for nothing -- even cheaper than a raspberry pi.

Don't they work with the batteries removed?

  Most phones do not have removable batteries anymore.

    All phones have removable batteries. It just depends on how dedicated you are!

It's pretty easy (at least for single devices) to use a timer powerpoint switch and guess/tweak an appropriate duty cycle to keep the battery topped up often enough without leaving it charging 24x7. I have an old iPad that's been running for 5+ years with 1hr/day charge time. (I cooked it's predecessor's battery to a screen-cracking-bulge in about 9 months.)
