Best 4000 mAh Mobile Phones

Battery backup or battery life is the most important factor while deciding to buy a smartphone. After all, what good is a phone if its battery runs out? Plus in today's busy life, no one wants to charge their phone frequently.

Battery capacity is measured in the milliamps or popularly denoted as mAh (short form of milliamp hour). The number provides an estimate of how long the device will last.

For example, a 3000 mAh battery can power a device requiring 100 milliamps for 30 hours, while a 4000 mAh battery can power the same device for 40 hours.

Bigger batteries can power your phone for a long time, however, it makes the phone bulky as well. Choose the phone which suits your needs between mobility and longer battery life.
