Solar

I would recommend the back panel or anywhere possible for small solar panels around the phone. Or if a case fabricated phone charged via cable or wireless..or even in the powerbanks(solar) great advantages.

Who will put their phone in the sun for charging 🤔 😂

Excellent point

Has been tried before. I guess it failed.

Why would anyone put a device with a battery in the sun. Unless you want to cause a fire.

Battery will degrade faster under the heat of the sun and may explode, cause 🔥, and injury.
