One of the interesting marketing strategies by Motorola team with Moto G is to present the phone without a charger. Instead of a standard charger unit, each Moto G is only equipped with a standard USB cable.
This is actually a pretty neat idea, which means that your Moto G will work with any standard charger that is usually present in most household. It is believed that the absence of charger is effective in bringing production cost down, thus Moto G can come out with a reasonable price.
Universal and efficient as it might be, the standard USB cable has run with several issues such as: phone reboot when plugged in during charging or phone refuses to charge when the battery runs down. Another familiar problem is that Moto G turns itself off and simply refuses to charge.
How to Fix Moto G Reboot When Charging or Won’t Charge:
Ultimately, the charger that you use to charge your Moto G by a USB cable will define the charging process. Simply try different chargers that you have with you and it is highly likely that you will find the most suitable one among many.
The ideal specification for the charger that works most compatibly with Moto G is a charger rated between 500mA and 1.5A. Within the range provided, the higher the rating, the faster your Moto G will charge.
