LG G2 uses 3000mAh SiO+ Battery

The LG G2’s specially engineered 3,000 mAh SiO+ battery was created to complement the phone’s slim, ergonomic shape and to impress with its long life. This high-density battery features a unique step design that provides maximum capacity in a slim form factor, enhanced with Silicon Oxide Plus technology for efficient power.

The Samsung Galaxy S4's battery is 2600mAh, 1570mAh for Apple iPhone 5s and 2300mAh for HTC One. The capacity of LG G2's battery is high enough.


Tips: What's SiO+ Battery
SiO and SiO+ based batteries are nothing but an enhanced version of the Lithium-Ion (Li-Ion) batteries. SiO batteries use Silicon based material as the anode in the battery (SiO stands for Silicon Oxide). The Silicon based anode brings better battery performance in to the traditional Li-Ion batteries.

Most of the traditional Li-Ion batteries use graphite as the anode. Many researches has been conducted by various universities and research firms to find alternatives for graphite based anodes in the Lithium-Ion batteries. Some of the recent researches have found that Silicon based anodes can significantly improve the storage capacity of the Li-Ion battery. Among many Silicon based anodes, the SiO based anodes were found to be most efficient, providing great electrical storage capacity without increasing the size of the battery.
