Motorola mobile phones equipped with a 5,000mAh cell battery usually last a day or two. However, constant screen use will reduce your battery life to 14 to 16 hours. Several apps running in the background, Bluetooth and Wi-Fi connections, loud volume and super bright screens also affect battery performance and will drain it quickly. The average lifespan of a typical Android battery is 2 to 3 years. Watch out for warning signs and have your phone installed with a new battery before the end of its life cycle.
