Tech tip: How to keep your mobile device’s battery healthy

We all know that a battery drains at different rates depending on use. Obviously, the more things you do with your device, the faster you drain its battery. However, if you are finding yourself running out of juice earlier than you think you should, you need to do something about it.

Battery calibration

Most mobile devices today use lithium-ion (Li-ion) batteries. Experts say it is essential to calibrate the Li-ion battery periodically. Calibration supposedly takes care of your battery’s health and charge cycles. Most tech blogs, in fact, suggest this as a first step to address the sudden battery drain problem.

Don’t be confused between “battery life” and “battery lifespan”. “Battery life” is the amount of time your device runs before you need to recharge to keep it going. Whilst “battery lifespan” is the amount of time your battery lasts until it flatlines. Depending on how it is used and abused, a lithium-ion battery typically has a lifespan of three to five years.

Calibration improves the lifespan of your battery, not it’s life. If you use your device non-stop, the battery juice will still drain fast even after a calibration.

Battery calibration does two things:

      1. It conditions the battery.
      2. It helps the software calculate the range of battery life.

Calibration is easy to do. Here’s how:

Step 1:  Once a month, drain the battery completely.

To expedite battery drainage, turn on all battery hogging features. Use your device until it turns itself off.

Step 2:  Recharge the battery without any interruptions until it is fully charged to 100%.

Once your device powers off, leave it for some time preferably overnight. Don’t charge it until the following morning. Allowing the device to sit overnight will further drain the battery. But if you can’t afford to wait that long, you can skip this step.

For Apple devices, they’re advising to keep on charging two more hours after you’ve reached 100% of your battery. But some argue this could overcharge the battery. If you’re not comfortable leaving your device charging for additional hours, unplug the charger when charging hits 100%.

Step 3:  Reset your device.

This is important especially if you just upgraded your OS. This final step will refresh all your applications – and hopefully fix the issue.

It only takes once a month to take care and extend the lifespan of your battery. The steps are quite simple: drain, recharge, reset.

Finally, keep in mind that going from zero to 100% and then 100% to zero on a regular basis will put the most strain on your lithium-ion battery. Don’t do it!
