These days, one cannot imagine a day without a smartphone. Hence, it is important to have a good battery backup for the handheld device. Although most smartphones these days have a 5000 mAh battery, sometimes even after charging the phone does not charge at all.
All the latest smartphones provide good service initially in terms of battery life, but the battery backup capacity decreases over time. But if you do these few things, the battery backup of the phone will last longer.
