What should be the size of a smartphone battery?


Battery life is one of the biggest concerns of smartphone users. These phones are capable of doing so much that they put a lot of strain on their batteries, resulting in sub-optimal battery. People who usually migrated from feature phones complain the most about lack of battery backup, given that they are used to charging their phones in 2-3 days, compared to the smartphone requirement of almost daily charging. The battery of a phone is like the fuel tank in a car, and the car's range on a single full tank depends on how big the tank is and how efficient the engine is. But unlike cars, you don't get fuel efficiency figures, therefore it leaves people confused about the battery size they should opt for. So what's the solution? Well, there is no precise solution, but generally the display size puts a lot of strain on the battery and therefore choosing battery size according to display size makes sense.


Battery life


We compared all the phones with a similar display size and came out with the average battery size that they have. Based on that data here is the recommended battery size. These figures are for Android phones only. As different operating systems put different demands on the battery there is no single size recommendation for different operating systems.


5 inch display


Most phones these days that come with a 5 inch display have a 2000 mAh battery, such as the Micromax Canvas HD, Karbonn Titanium S5 and HTC Butterfly. In case of 5 inch phones, 2000 mAh is the minimum that you should be looking at, however bigger is always better and you can get phones with 2500 mAh or bigger batteries.


4.5 inch display


Currently, phones with a 4.5 inch display come with a wide variety of battery sizes starting from 1600 mAh to up to 3450 mAh. However, 1750 mAh is the average battery size that you must look for. You can consider phones like Karbonn A21, Xperia Ion, or Xolo Q800.
