Samsung today unveiled a new battery kit accessory for the Galaxy S4 which allows you to charge up a spare battery while you use another inside your device. The kit includes a second battery, a protective case, and a nifty little charging unit that accepts a micro USB cable.

The charging kit allow you to use your Galaxy S4 for longer in between charges by swapping out its battery for a fresh one when it’s dead, and it’s ideal for those lengthy road trips or long days away from the office.

The Galaxy Note III is one of the most anticipated phablets of 2013, but Samsung has done a great job of keeping the device a closely-guarded secret ahead of its unveiling. We have no idea what the device will look like, and all we know about its specifications is what we’ve gleaned from rumors and educated guesses.

But two new reports claim that the Galaxy Note III will come with the latest Android 4.3 operating system pre-installed, and a massive 3,450mAh battery — the largest battery Samsung has ever put inside a smartphone.

A new rumor has surfaced claiming that LG’s much-anticipated G2 will be featuring a 2,610 mAh battery, tucked away neatly behind the handsets back cover.

1080p displays are the latest must-have for high-end smartphones, but you may not see one on Google’s next Nexus. According to the latest rumor concerning the Nexus 5, the device will skip a full high-definition display and instead focus on a better camera and a bigger battery.

LAS VEGAS, CES 2013 – We’re always a bit stumped at how PhoneSuit is able to stuff so much battery in to their batteries. Their new Flex line is another great example; those little battery logs above each contain 2600 mAh of juice, which is more than any iPhone battery case I can think of. And that’s not even the coolest thing about them.
