Slightly more capacity

The battery comes with a new cover for the device. Both battery and the lid fit perfectly with the SGS II. No wonder, since it is original Samsung accessories, as you can expect the same. The SGS II is slightly thicker and heavier, but not thicker than it is at the bottom of the speaker anyway. The difference in weight does not fall on negative and by the somewhat greater thickness the unit is actually even better in your hand. In addition, the camera lens is protected by a little, because the lid is slightly higher than the protrusion of the camera unit.

After several discharge / charge cycles, I'm quite happy with the battery. It should of course be aware that this battery "only" brings about 20% more capacity with himself. Miracles are thus naturally to be expected. For me, the example is sufficient to longer get along a day without recharging. With the standard battery I have the morning of the third day no longer sufficient energy for the entire day, so I have two days already reloading to come the next day to make ends meet. The Extended Battery is however for the third day still sufficient energy in order to load until the evening of the third day must. Depending on usage patterns that can of course be different. Who usually in the evening of the second day already has quasi the battery is empty, will also create the Extended Battery another day. And who works nonstop to the SGS II and / or plays well this battery will easily get one day empty ...

Whether you really need the extended battery, everyone must decide for themselves. Who needs a little more flexibility, the can this Extended Battery are definitely recommended.

By the way, more frequent recharging of lithium-ion batteries not harmful. The number charging cycles, which are specified by the manufacturer, based on 100% cargos. So twice 50% load correspond only one full charge cycle. And Li-Io batteries are the most "worn out", when they are held at the ends of the load limits. Load continuously at 100% or continuously discharged completely damage the battery far more than, for example, to operate it between 30 and 80%. Only occasionally you should recalibrate the battery (ie, completely full load, discharged completely (at least less than 5% or until the device turns itself off precisely) and once fully charged). This is necessary so that the electronics know how much energy the battery can really absorb. Only then also the percentage charge level can be properly calculated and displayed.
