A good battery capacity is one of the most important features that a smartphone should possess. A battery that lasts long can save you from the hassle of finding a charging socket, or carrying a power bank everywhere you go. Moreover, poor battery performance can prove to be risky, as you might end up with a dead phone when you’re out and need your phone to book a cab, call someone important, or look for directions. So let us understand the science of battery power, and how much of it does a smartphone need.
1. Battery Capacity
mAh, the unit used to denote battery capacity, stands for milliampere-hour. There are innumerable smartphones with varying battery sizes in the market these days. You’ll see ads flooding with companies boasting about their big 5000 mAh battery phones on billboards and on TV. The question arises — does a bigger battery size mean a longer battery life? The answer is no. A smartphone’s mAh rating alone doesn’t give you a good picture of its battery life. Battery life is a tricky picture, with a number of hardware and software variables that affect it.

2. Battery Size vs. Battery Life
The battery size and the battery life of a smartphone might not always be correlated. The battery is responsible for powering all the hardware in a smartphone, including the processor, display, and all other features that the device has. Different pieces of hardware use up different amounts of battery power, even if they’re from the same category. For example, low and mid-range processors consume considerably lower amounts of power than their flagship counterparts. Irrespective of the hardware category, higher performance requires more power. This is generally the reason why budget smartphones often have longer battery life than flagship phones for any given battery capacity. Moreover, additional pieces of hardware will suck up more power from the battery. Phones with extra hardware such as stereo speakers, quad camera stack and 4K display will need more juice than the regular ones.
Another factor that significantly affects the power consumption in a smartphone is the specifications and features. A better set of specifications and large number of features mean a faster drainage of battery. These include the display quality, fast refresh rates, 5G connectivity, gaming features and other performance-based features.
Conclusively, two different smartphones with the same battery size may have varying battery lives owing to the difference in their features and performance. As a consumer, it’s important to get the balance right between battery and performance in your desired price range.
3. How Much Battery Capacity Do You Need?
How you use your phone should be a major factor while deciding this. If you use your smartphone mostly for basic tasks like browsing social media, texting and calling, you should be good with a 3000 mAh battery to last you a day. If your usage involves more battery-intensive tasks such as gaming, navigation, shooting videos or watching movies, you would want to go with bigger batteries in the range of 4000-5000 mAh. 5000 mAh battery phones would be sufficient for the heaviest of users, given they have a good battery life. Currently, the best phones under 15000 INR offering the best battery life are Realme 7, Poco X2, Tecno Pova and Realme Narzo 20. On the higher price spectrum, mobile phones with the best battery are Realme 6 Pro, Realme X3 SuperZoom, Samsung Galaxy M51 and Asus ROG Phone 3.
Now that you’re equipped with the right information about how much battery capacity you need, you can make an informed decision about buying your phone. Additionally, whether you want mobile phones under 15,000 INR or above, you can purchase them on easy EMIs with the Bajaj Finserv EMI Network Card without worrying about the price tag.
