In any mobile device, battery life is a major concern and in
mobile phones, this has an greater importance. Over the past few years, battery
life hasn't really
improved. This isn't due to the non advancement of battery technology, but
more due to the increased power usage of components in phones, with the latest
screens and SoCs using more power than they did a couple of years ago. while
really they are advancing at a steady pace. For example, the HTC Desire (was one of the highest rated phones of 2010) utilised a 1400 MaH battery, while the HTC One uses a 2300 MaH battery. With 900 MaH extra capacity, the HTC One should have greatly improved battery life, while in reality it is not much different. This is because of the more power hungry components. One anomaly in 2013 was the iPhone 5S, which uses a 1570 MaH battery. This is far lower than other flagship phones on the market yet still manages to provide a days usage. This is due to the less demanding processor, as well as software optimisation in the closed Apple ecosystem. The drawback of current batteries is that they are still too large. To include a large 3,200 MaH battery such as the one found in the Galaxy Note 3 requires… you guessed it, a phone the size of a Galaxy Note 3. This means that phones cannot continue to get much thinner with the current generation of batteries, else battery life will suffer.
