Galaxy S5 to sport 2,900 mAh battery with rapid charging and new Li-ion tech?

We were able to confirm many of the Galaxy S5’s specs just a day ago, but many details continue to elude us as we look forward to the device’s official unveiling. Now, PhoneArena is offering us details on an important part of the phone, i.e. the battery. According to PhoneArena’s tipster, the Galaxy S5 will sport a 2,900 mAh battery – that’s 300 mAh more than the Galaxy S4’s, and the battery will also support rapid charging like the S4 and Note 3, allowing it to fully charge under two hours.

The S5’s battery will also be a new type of Li-ion battery that can store 20 percent more energy than batteries currently on the market, allowing it to offer more battery capacity in the same size as a lower capacity battery not using the new Li-ion tech. These batteries are made by Amprius, a battery startup based in Silicon Valley, and have been shipping to smartphone makers recently, and the Galaxy S5 could become one of the first smartphones to be powered by one.

How well will a 2,900 mAh battery cope with the insane hardware inside the Galaxy S5, especially the QHD (2,560×1,440) display? Well, that remains to be seen, but hopefully it will be good enough for at least a day’s worth of use with medium usage, or consumers might just start hating all the hardware advancements if they can’t manage to get through the day with their new and shiny flagship.
