According to PhoneArena, the next Samsung smartphone might be equipped with a 2900 mAh capacity battery and rapid charging technology.
Charging of the device could take place in less than two hours, the report states.
This new type of lithium battery can store 20 % more energy than the batteries of devices currently on the market.
The new S5 will be provided by Amprius, a start-up in Silicon Valley that is already producing improved smartphone batteries.
The new battery is said to have the same size as its predecessor.
A recent report claimed that the device will be released in two variants: model with a metal housing and another made of plastic.
