South Korean tech giant Samsung Electronics has claimed that it had developed a new technology that will increase battery life for smartphones, without having it to take up more space.

Reports say a team of researchers and scientists from Samsung's Advanced Institute of Technology division were able to develop a material that coats crystal graphene on a "silicon surface", making battery life last longer by twofold.

Korea IT Times recently reported that the new technology could be used on Samsung's new devices after the next three years. Other reports added the new technology still has a long way to go and wouldn't show up yet, as it is still part of an on-going research by the South Korean tech giant.

Engadget has reported that Samsung used in this experiment batteries that were around 1.5 to 1.8 thicker than the current conventional batteries. According to a report, new battery technologies should meet safety standards first, before they can make it out into the market.

Another new report that surfaced claims another South Korean tech giant, LG Electronics, had also made a breakthrough by developing a new small sized battery that could increase battery life for smartwatch devices.

The new battery was developed by LG Chem Ltd., the chemical division of LG, according to reports, and the biggest chemical company in South Korea. The new battery is said to have a hexagon shape that can be fitted into a wearable device such as a smartwatch.

Phone Arena reported that LG's new battery has the ability to increase usage time by 25 per cent, giving smartwatch users an extra four hours time. The Register UK reported that the South Korean giant had developed the new battery technology along with another company, but it's unclear which company LG had worked with.
