> It died in 2018 on a camping trip when I let it trickle-charge on a Solar Panel. Did the battery die or the whole phone somehow?

Trickle Charging it caused something do go really wrong with the display circuitry and over half of the screen was randomized color-static looking garbage. The phone itself seemed to operate fine, but the display issues rendered it useless. I later learned that if you use a portable solar panel battery pack, let the pack charge and then plug in your phone. Don't plug a near-dead solar panel battery pack into your phone and let. There's something about the low-voltage trickle-charge that can be terrible for electronics. I'm not an EE, so I don't understand the details. Perhaps someone else can explain it better.

I'm interested in learning more about this. I recently got a USB solar panel (with no battery). I wonder if it has anything to do with voltage dropping way below USB spec (which I've seen when the panel can't provide the current the device wants, which seems to be pretty easy when the panel is small and/or not in full sun).

  I've set myself up some backpack panels + a separate usb batter Generally I've found that batteries will let you charge xor discharge, and won't let you do both. I assume that you'd get unexpected voltage/amperage on the discharging side, from the charging side if you tried to do both at the same time
