How To Keep Your Devices’ Batteries Alive As Long As Possible

How To Keep Your Devices’ Batteries Alive As Long As Possible

Love them or hate them, batteries power everything you hold dear, or at least everything inside your phone. You might have a brand new iPhone with a fully charged battery or a dying iPhone 6, whose battery is so degraded it requires a replacement from Apple (at least it’s discounted). Sure, all batteries degrade eventually, but you can take some preventative steps to keep them in good health for as long as possible.

To keep it operating nominally, you’ll need to occasionally participate in some time-consuming activities, or go against your habits and beliefs as to how you should charge (or discharge) a battery. For the most part, batteries can take care of themselves and combat our bad habits as long as you monitor a few factors. Here’s what you should look into when determining the health of your battery, and how to keep it full of electrons until it’s time for a replacement.

In university, my laptop’s battery began to bulge, leaving me with two options: Replace it with a new one, or wait until it pops out of my laptop during class (guess which one I chose). In retrospect, the chances of my laptop catching fire were pretty high, and it would have been pretty devastating if it had gone up in flames. If your battery starts to bulge inside your device, consider it a fire hazard and dispose of it properly. Don’t be like me. Replace your battery.

Extreme Temperature Isn’t Good

Not too hot, not too cool: A battery at the extreme ends of the weather spectrum is an inefficient one. You should try to keep your battery’s temperature between 5 to 45C. Heat causes a battery to speed up its chemical reactions, which translates to a battery that drains faster than it should.

A cold battery is equally inhibited by the frigid weather, and has a lower capacity compared to a room temperature battery. One more thing: Avoid charging your battery in below freezing temperatures, as you could permanently damage its capacity.

Unplugging and Discharging

Every battery has a lifespan, measured in the number of cycles. A cycle is complete every time the battery is fully recharged, whether all at once or over the course of a few days. A battery charged from 80 per cent to 100 per cent every day will take five days to complete one full charging cycle. Going from completely dead to fully charged is another charging cycle.

In general, you shouldn’t allow your battery to fall to dangerously low levels, and should start charging your devices when they fall below 20 per cent to avoid placing stress on a battery by charging it from such a low level (charging from extremely low levels ages the battery and reduces cycle count). If you want, you can unplug your device after it’s fully charged, though most devices automatically cease charging when their battery is full, negating the worry of degrading the battery.

There’s even an entire industry built on selling backup batteries for our smartphones and tablets to keep them going once the battery runs out.”]

Charging a battery also means you’re expending a charge cycle, so the fewer times you charge it, and the less you charge all at once, the longer it will last. That means battery saving measures such as Power Save mode on your devices should be considered when you’re looking to maximise your time up and running.

Monitoring Your Laptop Battery

macOS: Monitoring your battery on the Mac is easy, with the right app. If you’d rather not install any new software, you can look at your Mac’s system information and find the information you need to determine the health of your battery.

  1. Hold the Option key and click the Apple menu icon. Choose System Information.
  2. Under the Hardware section of the System Information window, select Power. The current cycle count is listed under the Battery Information section.

Apple has a list of maximum cycle counts for each laptop so you can see how close you are to the limit, when battery life starts to degrade.

Alternately, you could install a more visually pleasing app such as Battery Health. The free app offers a simple and colourful view of your battery’s performance and discharge history. You can also view the time spent plugged in or running on battery power to get a better idea (and eventually alter) your charging habits

Windows 10: To see how your battery is faring in your Windows 10 laptop, you can go one of two ways. First, you can use Windows 10 and the command line to generate a battery report, which will detail our battery’s usage history. You can see its cycle count, maximum capacity, current capacity and usage time to determine whether the lifespan you’re getting is in line with the lifespan advertised.

Don’t feel like going into the command line? Download a battery analyser app such as Battery X, which presents your battery health in a clean and simple interface, much different than the HTML battery report Windows 10 generates.

Monitoring Your Smartphone Battery

iOS: Apple, thanks to its unpopular decision to throttle iPhones with older batteries, is updating its battery management service in the upcoming iOS 11.3 software update. You’ll be able to see the health of your battery as a percentage, and determine whether or not you’re due for a replacement. If you are too impatient to wait, you can always download a battery monitoring app and use it to see how those cells are doing.

Android: It’s easy to see what’s draining your battery in Android. You can take a look inside Android’s battery settings to see which service or app is using all of your juice, and adjust your habits accordingly.

You can also look into enabling Android Doze, which essentially stops Android apps from constantly draining your battery life with requests for location data, notifications and other unseen actions. Want more information on your battery health? Try GSam Battery Monitor, which will display a wealth of data about your battery, including its capacity, cycle count, usage time, and which apps are using the majority of your juice.
