Generally, phone, MP4 are set to be power off here.

The battery output current is not enough, reduce a lot.

Voltage: 3.55 v; The residual capacity: - 2%

Voltage: 3.50 v; The residual capacity: - 5% have voltage but the current decreases

Voltage: 3.42 v; The residual capacity: - 8%

Voltage: 3.3 v; The residual capacity: - 10% affect capacity

Voltage: 3.0 v; The residual capacity: - 12%

Voltage: 2.7 v; The residual capacity: - 13%

Battery is about to scrap, the capacity will lose a lot!!!!!!The residual capacity is proportional to voltage, not absolute, only the lowest patient is 0. If less than 0, the discharge is negative, the battery may be completely without electricity, then the battery is scrap. As in the negative - 5% - 8%, it is the deadline basically, on the lowest voltage: 3.2-2.7 v, current is very small and slow when recharge. It impacts a lot.
