4 ways to extend the battery life of your gadgets

+

Just about to snap a photo and your (supposedly freshly-charged) phone dies on you? We have all experienced batteries in devices like laptops and smartphones slowly losing their capacity over time. This is because batteries have a certain number of charge cycles, usually between 500 and 1,000, before they start degrading significantly. When this happens, devices have to be charged more often than before.

But there are ways you can keep your gadget's battery in tip-top condition and prolong its lifespan.

1. AVOID FULLY DISCHARGING YOUR BATTERY

Older devices use nickel-based batteries that lose their capacity if they are not fully discharged before charging. But the opposite is true for the lithium-based batteries used in modern gadgets. Fully discharging a lithium battery is bad for the battery.

Instead, you should charge devices soon after letting their battery run down. According to the website Battery University, it is best to charge the battery after it drains to about 50 per cent.

But you may want to fully discharge the battery occasionally (once a month) to keep it calibrated, which lets the gadget estimate the remaining amount of battery life accurately.

2. UNPLUG YOUR GADGET WHEN FULLY CHARGED

Lithium batteries will degrade in capacity when it is kept at a high charge voltage. Therefore, it is advisable to remove your gadget from the charger when it is fully charged.

For laptops that generate a lot of heat, it is recommended to remove the battery if you plan to keep it plugged into the power socket. This is because high temperatures will reduce the battery's lifespan.

3. KEEP YOUR GADGETS COOL

Batteries do not fare well in warm environments and will suffer from capacity loss. It is best to keep your gadgets at room temperature and avoid leaving them in a car out in the sun.

4. STORE YOUR GADGETS WITH 50 PERCENT CHARGE

If you intend to store your battery or gadget for more than six months, you should ensure that it has at least 50 per cent charge. Storing it at full charge will shorten the battery lifespan while storing it at zero charge may lead to the battery becoming unusable.
