Since the advent of smartphones, battery backup has always been a spot of bother for all voracious users of the device. The main reason behind it is the fact that the devices they use do not have enough battery life which will last for long on a single charge. This phenomenon led to the invention, production and marketing of the power bank which was at its zenith in 2016 and 2017. However, the mobile companies saw the problem, and they did not delay to address this issue by increasing various aspects of their battery in particular and of the phones in general.

Strength of battery
The strength or magnitude of batteries is one of the key factors to look for while choosing a cell phone battery. While it is true that batteries are generally above the two thousand milliampere-hour (mAh) mark, the higher that amount, the better the battery is sustained. For example, if a phone has a 4000mAh battery, then it is expected to last all day if it is charged to one hundred percent in the morning. This is also directly proportional to the speed at which the battery is charged and the base of it as well.

Battery base
Nowadays, almost all batteries are lithium-ion based. However, one must be very careful while choosing a mobile phone and must check whether the base of the battery is actually lithium ion or not. This is because if it is otherwise, then the user would have serious issues with it. The lithium base provides for a stable platform on which the battery works, and it also helps to distribute the workload of the battery evenly to all its parts.

Processor
This feature would be best explained with an example. The Redmi Note 4 and the Redmi Note 5 Pro have the exact same battery magnitude in terms of mAh, but the latter’s battery lasts much longer than the former’s simply because it has a faster and better processor. The point is, if a cell phone battery of considerably good magnitude is combined with a high-end processor, then it becomes even more effective. Consumers should keep this in mind while buying a phone.

Charging speed
Time is of utmost importance for a fast-paced life. Hence, a cell phone battery and its longevity are greatly judged by the speed at which it gets charged. Many smartphones have now introduced flash charge or fast charge which makes sure that the user gets his phone charged in a jiffy. This would also keep the battery in a healthy state, as it would not be exposed to prolonged hours of electric charge.

So all you need to do is keep the above-mentioned points in mind and then select the battery for your mobile phone. Do some research and consider your budget before buying one.
