Many smartphones nowadays come with inbuilt batteries, making it difficult to swap the battery in case it gets damaged. Hence, it is imperative for us to ensure that we take proper precautionary measures to ensure our phone’s battery lasts long and gives us maximum performance. There are certain measures one can take to make sure their phone’s battery works the way it was intended to.
Let’s take a look at some simple steps to help you properly care for your smartphone battery.
Keep It Charged…
You may remember reading somewhere that batteries need to be discharged completely once every month to keep them running at full potential. This was something known as the“Memory effect”, and was prevalent amongst nickel-based batteries in older phones like Nokia 3310. However, with the advent of lithium-ion batteries the situation is quite contrary. The lifespan of these batteries are known to shorten when they are completely discharged on a frequent basis. To get the most out of lithium-ion batteries, one should try keeping them charged above 50% as often as possible.

But Avoid Overcharging
Although we mentioned that keeping your phone charged is the way to go, it is also fair to mention that overcharging your phone’s battery can have its downsides too. But lucky for us, most modern phone chargers will automatically cut off charging when it detects that the battery is full. However, leaving the phone on charge will put it into a constant charging-and-cutting-off cycle that can be unfavourable for a battery in the long run. For this reason, it is best to unplug your phone once it reaches 100% charge. It is highly recommended that you do not place your phone on charge overnight as you will always end up overcharging it.
Keep Calm And Keep Your Phone’s Battery Cool
It is easy to get worried about how we charge our phones, to the point where we forget that there are other factors that influence battery life which are not charging related. Lithium-ion batteries have an arch nemesis that can bring about its death and that enemy’s name is… *drum roll*… HEAT! Your smartphone’s battery can severely deteriorate when it gets hot, and you don’t need to be using it for the damage to occur. Research shows that at 0°C, a lithium-ion battery will lose about 6% of its maximum capacity in a span of one year. Raise the temperature to 25°C and you will notice a jump to 20%, and when the temperature reaches 40°C, you can expect to see a loss of 30% in one year! So remember, always keep your phone away from direct sunlight or other sources of heat that could significantly impact your battery life.
Zero Is A Big No-No!
That’s right! If you intend to keep your phone’s spare battery or the phone itself in storage for extended periods of time, it is a very bad idea to drain the battery completely before storing it. Lithium-ion batteries won’t drain at a superficial rate, but they do tend to lose 5-10% of their charge every month or so. And when these batteries reach absolute zero, they become very unstable and stand a risk of exploding when charged. To prevent such accidents from occurring, lithium-ion batteries are manufactured with a failsafe cut-off circuit that prevents it from ever charging again once the charge drops below safe limits. So if that ever happens, it will reduce your battery to nothing more than a fancy paperweight. Most techies would agree that it is best to leave your battery with at least 40% charge before storing it. Also, don’t forget to store them in a cool and dry place for prolonged longevity.
Use Airplane Mode To Charge Your Phone Quickly
We often come across situations where we need to quickly charge our phones during that short 30-minute drive from one location to the other. In such cases, it would make sense to put your phone in Airplane mode while it charges, as it speeds up the charging process by quite a large margin. It also keeps your battery temperature lower as the phone is left in an idle state that doesn’t put stress on the battery. Besides, you don’t need to take calls while you drive, and having fewer distractions is always welcome while you focus on driving. If switching to Airplane mode is not an option because you’re expecting an important call, turning off Wi-Fi, Bluetooth and cellular data can also help improve charging to some extent.
We hope these simple tips help you take good care of your phone’s battery for years to come. You probably will end up buying a new phone within a couple of years anyway, so don’t stress too much on sticking to the book. Just remember to keep it cool, literally!
