Samsung Galaxy Nexus External Battery Backups- 5 Juice Packs that Deliver

The Samsung Galaxy Nexus will give long standby times and long talk times (even on 3G) but as soon as you start up those apps it is a different story. Playing games, watching videos, processing images, using office apps- these drain a battery quickly, especially if you use Bluetooth or WiFi at the same time.

Something like the Battery Pro app will certainly help you manage usage efficently and keep that dead screen away for longer.

It is also a pretty stylish device and feels as good in the hand as it looks.

They still manage to carry a respectable charge at 2600mAh and this will comfortably recharge a GN.

It might be easy to mistake some of the more colorful ones for a lipstick but this would probably not be terminal.

The black one is macho enough for tough guys.

Solar rechargers sound great but can be slow. You also need sun so they are not one hundred percent reliable. This is a rechargeble battery that can be taken out with 3200mAh already onboard that is topped up whenever the sun is available.
