A powerful processor and bright screen could do a lot of damage to a phone’s battery life over the course of the day. The LG G2 will pack a 3,000mAh battery, which should help it last through a day of heavy use. Additionally, LG gave the G2 a SiO+ battery.
SiO+ are batteries developed by LG that contain silicon oxide (SiO) instead of the graphite component in traditional lithium-ion batteries. This means a partial increase in the battery’s capacity, somewhere in the neighborhood of 6 percent.
