How to Charge the Battery on Nexus 7
Fortunately, setting up your Nexus 7 tablet isn’t complex or time-consuming. You pretty much have to liberate the tablet, assemble it, charge the battery, and then set up your Google account. That’s it.
The first thing you should do with your Nexus 7 is give it a full charge. Obey these steps:
Connect the USB cable to the wall adapter.
The cable plugs in only one way.
Connect the other end of the USB cable to the Nexus 7.
The cable attaches to the bottom of the tablet. Again, it plugs in only one way.
Plug the wall adapter into the wall.
Upon success, you may see a large battery-charging icon appear on the touchscreen. Yes, it happens even though the Nexus 7 isn’t turned on yet. The battery-charging icon lets you know that the Nexus 7 is functioning properly, though you shouldn’t be alarmed if it fails to appear.
Your Nexus 7 most likely comes partially charged from the factory, though it is still recommended you give it an initial charge, just in case, as well as to familiarize yourself with the process.
The USB cable is used for charging the Nexus 7 and for connecting it to a computer to share information or exchange files.
You can also charge the Nexus 7 by connecting it to a computer’s USB port. As long as the computer is on, the tablet charges. Even so:
The battery charges more efficiently if you plug it into a wall rather than charge it from a computer’s USB port.
The Nexus 7 doesn’t feature a removable battery
