Samsung is looking to appease smartphone fans who have been critical of the current generation of handsets due to poor battery life which can leave you searching for your charger well before bedtime each day.

It is promising that the smartphones it launches in 2012 will come with much better battery performance that will give moderate to heavy users the opportunity to use their mobile all day without worrying about the dwindling levels of energy left onboard.

Given that Samsung will probably be launching its first quad-core superphone in the form of the Galaxy S3 this year, you might rightly assume that this is a bold claim to make.

Battery issues have been plaguing a number of major manufacturers for some time now. The iPhone 4S and Nokia Lumia 800, both of which launched at the tail end of 2011, were the subject of many complaints from users who were experiencing pitiful periods of use between each charge. Software fixes were rolled out in each instant, but this did not entirely amend the issues.

The nature of smartphones means that most people are using them for doing many more things from day to day. You could not check your email, browse the web, play complex games, download apps or make VoIP calls on older handsets and so they would use less battery and last for days or weeks at a time between charges. This is not possible with modern handsets, which most people cannot leave alone for five minutes thanks to their diverse functions, meaning you can often find that your mobile dies before the working day is over.

Another issue is that the phones are getting larger screens and more powerful hardware, all of which needs more power to operate and so batteries need to store more electricity and output it at higher rates. The 4.7 inch screen of the HTC Titan, the 5.2 inch display of the Samsung Galaxy Note and the 4.3 inch display of the Motorola RAZR are all culprits in this instance, but manufacturers are not likely to take a step back now that big screens have been established as the norm.

Higher resolutions and multi-core processors are also adding to the potential problems. The Samsung Galaxy Nexus was one of the first phones to sport a high definition Super AMOLED screen, while a range of dual and quad core mobiles, such as the HTC Edge, are set to arrive throughout the year.

The only way that Samsung can meet its promise of giving users day-long battery life in 2012 is to greatly increase the capacity and consequently the size of its cells. This might have an impact upon the slimness of the mobiles it releases. The Nexus S was superseded by the Galaxy S2, which was thinner than ever, but if battery life is a top priority for Samsung it could be that the Galaxy S3 is a little thicker around the middle.
