When the mighty Li-Ion battery of the Samsung Galaxy S4 (2600 mAh capacity) is not enough, owners can now make use of a spare battery and a helpful charger kit, which has been recently launched by Samsung. Compatible with all variants of the smartphone, this extra charge is enough to double productivity levels and ensure connectivity for longer periods of time.
The spare Galaxy S4 battery comes with a compact charging and carrying case and a microUSB travel adaptor that can power other mobile devices as well. Those that choose to purchase th accessory can replace an almost empty battery with a fully-charged one in a matter of seconds.
As you may already know, Samsung is among the few manufacturers that still make devices that pack easy-removable batteries. All users need to do is pop-open the back cover, take the battery out and place the spare one inside. The simple nature of this procedure has influenced many Android owners to forget about thick battery extension cases and opt for a back-up unit instead.
Based on the latest Galaxy S4 battery tests, a spare unit will offer enough juice to use as 14 hours of regular talk time, around nine hours of web browsing or 10 hours of video playback.
The official price of the kit is $49.99 but the best offer available can be found on dear old Amazon: just $40.92. Amazon also notes that a Korean-made counterfeit is already on the market with less impressive results.
