I recall having a Nokia mobile that lasted a week on one charge. My Samsung Galaxy dies within 24 hours, which can be annoying to say the least. In airports all over the world you see poor souls wandering around terminals with smart phone and charger in hand looking for the ever elusive charging point.
The simple fact is that all the old Nokia had to do was make phone calls, thats it, period. The smart phones of today are less phones than mini mobile computing platforms that do everything from photographs, web browsing and emails to play movies, music and games. Oh yes, they can also make the odd phone call.
It is little wonder that batteries struggle to keep up with the ever increasing demand.
There is something you can do to help your poor battery out though. In this article from CNet you find the apps that are the biggest battery drainers on your device.
