solar charger

When i connect my xperia to my solar charger, the screen on xperia activates like it detected something but it isn't charging.
My brother can charge his LG l9 with no problem though

What if you turn off your phone, also try to use your micro USB cable, I had a similar issue with a solar charger and it only charge my Xperias if they are turn off

Tried that, it works, it's charging, but after 20 seconds charger turned off and said that there aren't any devices to charge, my phone was at 56%

could you share the model and brand of the solar charger? this is something related to the solar charger, not the phone.
