🔋 B-P9 4000mAh Battery for Vivo

The battery model for this product is B-P9, with a 4000mAh rated capacity.

A 4000mAh battery provides a substantial capacity for everyday smartphone usage. However, actual battery runtime will vary depending on how the phone is used.

Battery consumption can increase with:

• High display brightness
• Mobile data
• GPS and navigation
• Video streaming
• Gaming
• Camera usage
• Background applications
• Weak cellular signal

Therefore, the 4000mAh capacity should not be considered a guaranteed number of hours of usage.
