For a user of the latest smartphones, several-day autonomy is an impossible to achieve ideal. Components have been miniaturized and ought to be more space for the battery. Unfortunately, the market demands phones as thin as possible, so that the battery still cannot exceed a certain physical limit.

Moreover, processors have gained extra megahertz and cores, the autonomy being sacrificed at the expense of performance as high as possible. In conditions of moderate to intense use, the owner of a top smartphone can end the day with low battery, although it was charged the night before. has decided that in 2012 will do something in this regard. The main ways of dealing with this problem will be to increase battery capacity and to increase the smartphone’s radio modules efficiency. An example in this regard is being given by the RAZR MAXX, which differs from the previous model by the fact that the 1780 mAh battery has been replaced with one of 3,300 mAh. We definitely applaud this move, but we cannot ignore the fact that the terminal thickness increased by 2 mm and the weight with 18 g.

Even sadder is the fact that an entry-level or mainstream smartphone doesn’t come with a better autonomy.  You would expect that a phone with 1 GHz processor and 3.2-inch display to offer a higher working time than a 1.2 GHz dual-core processor and a 4.3-inch screen. In reality, things are different, because rarely can be found an affordable smartphone that it’s being charged at every two days.
