How to maximize your battery life for your smartphones, tablets and devices

Chargie C Basic connected to charger and tablet

Everyone hates when their Lithium-ion (Li-ion) battery powered devices don’t last as long as they used to when new.  Not only do batteries degrade normally over time as they are used, but how you use your devices can speed-up the wear and tear of the battery leading to reduced battery lifespan and capacity sooner than later.

This issue is not just a problem for your own personal devices, but also an issue for work devices from always plugged in devices like GPS navigation, smartphone powered POS terminals to devices used for app testing in a test farm to demo devices on kiosks and more.

Let’s find out more about these Li-ion battery life issues, learn what you can do about it and see how this cool little device called Chargie can help you easily keep your battery healthy.  It’s so easy to use.  Just set and forget.  All without having to root your smartphone or tablet. 

Watch the video below for a quick summary of Chargie’s features and read the full article for all the details and more on how to maintain lithium-ion battery life!

Signs your battery is going bad

You may find that within a year or less of owning your device it may exhibit one or more of the following:

In pretty much all smartphones, tablets and many modern-day electronics, lithium-ion or Lithium polymer batteries are the standard type of batteries used because they hold a lot of charge in such a small package.  In other words, they have high energy density.  The downside is that they are very sensitive to how you treat them.  Doing the wrong things will reduce the battery’s life and capacity much faster than from normal wear and tear.

There are two things that are important to any rechargeable battery.  The capacity and the service life (lifespan).  The capacity is how much power it can supply per charge (e.g., 3500 mAh) and the service life is the how many times (charge cycles) the battery can be used before end of life (e.g., 500 to 1000 charge cycles).  When a Li-ion battery is not taken care of, both of these will suffer and your device will need a new battery sooner than later.

How do I keep my battery healthy longer?

The short answer: In general Li-ion batteries are negatively affected by high heat, full charges (especially when left at 100% for long periods of time), deep discharges, and heavy charge and discharge cycles.

Subjecting your battery to any of the above conditions will cause faster internal wear and stress to the chemistry of the battery causing it to have reduced capacity and a lower lifespan sooner than later.  In other words, the sooner your battery will not last as long on a charge and the lower the remaining number of charge cycles your battery will have before end of life.

Best Li-ion battery practices

Li-ion battery safety (Dangerous bulging batteries)

Note that battery lifespan and capacity are not the only issues when Li-ion batteries are not properly taken care of.  Bulging of batteries is the visible sign of a Li-ion battery that is starting to fail.  Not only does this damage the devices the batteries are in, but your device could now be a ticking time bomb that could explode or start a fire causing injury or death.  You only need to do a search on YouTube to see the dangers of Li-ion battery explosions and fires.

Though, Li-ion batteries are generally safe, if you start to notice that your devices are starting to expand out then it could be time to follow the best practices above to slow down the damage done to the battery.  If it progresses further, it could be time to get the battery replaced professionally.

For the safety of yourself, family and others, it’s not a bad idea to start taking care of your Li-ion powered devices today.  Find out next how to properly charge your smartphones, tablets and devices, next.

How to properly charge your devices (Smartphone, tablet and others)?

How does Chargie work?

Chargie is a little hardware device (USB dongle) that plugs in between your charger and your device, whether it’s a smartphone, tablet or wireless charging pad.  It is also Bluetooth paired to your smartphone or tablet running the Chargie app.  Together, the Chargie hardware and app are able to monitor your device’s state of charge, battery temperature and power coming from your charger to properly mange when to charge and when to stop charging based on what you configure in the settings.  It’s as simple as that!

Though Chargie works best with it’s companion app, it can also be used app-less to take care of your other devices like your Bluetooth speakers, smartwatches and more.

Do Smartphones, Tablets and Laptops have features to protect your battery?

Some manufacturers have started implementing Battery protection features that allow you to prolong and maintain your battery life and capacity.  These features are available in some devices from companies like Sony, Apple, Samsung, Google, OnePlus, Huawei and others.  If you have such a device, check it out to see what it’s all about.  Just note that they work well but may not be as configurable as Chargie.  So Chargie may still be the way to go for you.

Should you get a Chargie?

In the end, it’s your device and you will have to choose what method works best for you to manage your devices batteries that suits you and your lifestyle.  Chargie allows you to configure and manage your device charging based on your needs since there isn’t only one set of settings that is ideal for everyone.
