| Capacity Battery Capacity is a measure (typically in Amp-hr) of the charge stored by the battery, and is determined by the mass of active material contained in the battery. The battery capacity represents the maximum amount of energy that can be extracted from the battery under certain conditions. | 8550 mAh |
| Placement | non-removable |
| Charging The functionality responsible for recharging batteries in portable devices, such as mobile phones, significantly influences both battery lifespan and the practicality of daily product usage.The charging process, encompassing factors like voltage, current, and completion actions, is contingent upon the battery's size and type.Contemporary battery chargers dynamically adjust charging parameters based on the battery's current charging state. Charging an empty battery poses no safety risk, allowing for a quicker charging process. Consequently, many charging speed benchmarks, including ours, specify the battery level achieved after a 30-minute session on an empty battery.Standard chargers with a power output of 5V/1A, equivalent to 5W, serve as a baseline, with anything surpassing this speed classified as quick or fast charging. | 100W wired |
