Unlike cellphones of yore that were only used to make and receive calls and texts, phones today also serve as cameras, video recorders, music players, phonebooks, digital photo albums, navigators and even portable computers. Providing so many functions puts an extraordinary strain on a phone’s battery. Most cellphone/smartphone batteries today have a lifespan of approximately 500 charging cycles. Therefore, if you charge your phone battery at least once a day, you would need to get a new battery roughly every 16 months. Picking the right battery for your cellphone can be challenging if you don’t have the basics right. Here are some helpful pointers that can help you buy the right replacement battery for your phone.
