Question [Q] battery charging problem Motorola XT910.

Hi boys

I wanted to ask to see if anyone knows how to fix this fault.

It happens that when I connect the USB cable to the phone on the charging battery icon in the beam times indicating that the loading and sometimes not put it because it's not loading it gets.

The thing is that if you blow into the slot loading rack, connecting the cell begins to load normally.

It's not something that affects me much, but I wonder if there is any solocion to recover or fix the fault and may be what is affecting to be that problem.

Thank you!
