Maximizing Battery Life: The Ultimate Guide to Power Management for Mobile Devices

Spread the love

Mobile phones are an essential part of modern life. From allowing us to communicate with our loved ones to offering entertainment and enhancing productivity, our smartphones have to wear multiple hats. However, this comes at the cost of our phone batteries draining quickly.

Although phone batteries are getting better each year, they have a lot of catching up to do before their performance can be called satisfactory. Until then, the only way to avoid being stranded with a dead phone is to make the most of the battery life you have or carry mobile power accessories. The tips shared in this blog focus on the former. Follow them to maximize your phone’s battery life and make it last the whole day.

Turn Down the Screen Brightness

Our phone displays are made up of hundreds of tiny pixels and each pixel is continuously refreshing and feeding on your phone’s battery life. Pixels are the most power-hungry component of your phone. The larger your phone’s screen, the more pixels it’ll have and the more power it will consume. This is why reducing your screen’s brightness is one of the most effective ways of saving on battery life. 

No one needs their phone at 100% brightness all the time anyway unless you’re in direct sunlight where a brighter screen is required. You can change the brightness on your Android or iOS device manually or enable adaptive/auto brightness to keep the brightness at an optimal level at all times.

Apply Background Usage Limits 

Did you know that even when you’re not using a certain app it’s still running in the background and sucking on your phone’s battery life? Unless you’ve set background usage limits, this is most definitely the case. Apps are continuously drawing energy to get your location, auto-update, and more, whether in your hand, pocket, or mobile phone stand. You can disable these activities by going to the device settings, app store settings, or app’s settings depending on your phone model. 

If you’re being bombarded with useless push notifications from certain apps then you can save on battery juice by turning off notifications for those apps. Even widgets and live wallpapers consume a lot of battery life so disable widgets you don’t need and switch to a static wallpaper.

Close Programs When Not in Use

We’ve established that apps consume energy even when you’re not actively using them. This applies even when they’re in the app switcher. Having multiple apps opened in the app switcher also requires more processing power which drains the battery life further. If you’re not planning to switch between apps, then the best thing to do is to close the app from the app switcher as soon as you’re done with it.

Use Power Saving Settings and Mode

Imagine you have a long night ahead of you after a busy day and you suddenly notice that your phone’s battery is at 15%. This might send you into a panic. After all, mobiles are also essential devices for safety and emergencies. In these situations, simply dimming your screen and turning off apps won’t be enough. 

Most smartphones today are equipped with powerful power-saving settings and modes that kick into action when you need to maximize your battery life. This feature automatically reduces screen brightness, processor speed, and background data usage, giving you additional minutes to hours of battery life. You can also keep it on when your phone is decently charged and you’re not using it.

Set a Short Screen Timeout Duration

Keeping your phone awake consumes power so the logical way to save power is to turn off your screen when not in use. Most phones have a short screen timeout duration by default but you can go to your display settings and make the duration even shorter. This not only helps you save power when you forget to turn off the screen but also prevents accidental touches and dials.

Switch to Dark Mode

Another way you can lessen your screen’s power consumption is by switching to dark mode. Since black is the predominant color in dark mode, fewer pixels fire up when you’re using your phone, which means the strain on your battery life is also less. If you’re not a fan of dark mode, then a simple switch to dark wallpaper would also go a long way toward helping you lower excessive battery loss. 

Disable Unused Hardware Features

Hardware components such as Wi-Fi, Bluetooth, and geolocation consume a significant amount of battery life to function. If you want to save on juice, turn off everything that’s not necessary for you. 

If you’re using mobile data, there’s no need to keep your Wi-Fi on and vice versa. If you’re not currently paired to a Bluetooth device, toggle it off in the settings. At home and not using apps that need your location? You know exactly what to do to preserve your battery. This applies to VPN services and hotspots as well. Keeping your eye on the GPS is especially important because it pings your location to different apps continuously and hogs all the battery life.

Keep Your Battery Charged

A common mistake most smartphone owners make is not charging their phones enough and letting the battery life fall below 20%. Lithium-ion batteries should not be allowed to drop down to zero. The battery dying a couple of times won’t have a major impact in itself but if you let it fall below 20% regularly, you’re damaging the chemical ecosystem inside the battery and hurting its charge-holding capacity. 

This doesn’t mean you should keep your phone plugged in all the time because that too will harm the battery life. Instead of trying to charge your phone overnight unsupervised, it’s better to charge it partially before going to sleep and fully after waking up.

Prevent Exposure to Extreme Temperatures

Read the safety instructions for any device that contains a lithium-ion battery and you’ll find a cautionary note against leaving it in the sun or around extreme temperatures. High temperatures can cause thermal runaway, a dangerous phenomenon that can not only damage the battery life but also cause the battery to catch fire or explode. You should always keep your phone in a cool place away from direct sunlight—no extreme fluctuations in temperature whether hot or cold.

Update Your Phone Regularly

Mobile developers are always working to improve how apps utilize battery life. You must’ve noticed yourself that when new flagship phones are released, sometimes there are complaints of the phone overheating or the battery draining fast—we see brands scrambling to release patches and bug fixes to address performance issues. This is why you should never ignore system updates. Be vigilant and keep your device on the latest version of its operating system at all times.

Monitor Battery Life and Usage

Keeping an eye on your battery life and usage is essential to ensure its longevity. You can find out which apps are consuming the most power and limit your usage by going to your battery’s settings. Another thing to look out for is your battery vitals, namely temperature and health. If you’ve been using the same phone for years, the battery has likely undergone some level of degradation. 

Battery health will tell you how long your phone’s battery will last so if you see a significant difference in the time or notice your battery draining faster and faster after each charge, you’ll want to get it inspected. If you notice any bulging, swelling, or discoloration on your phone, you should immediately stop using it and take it for inspection.

Wrapping Up

Maximizing your phone’s battery life is about making smart choices on which functionalities you need to use and which ones you can give up on for some extra juice on your old or new gadget. You don’t have to apply all of the tips shared above, just the ones that serve your needs. Be aware of your battery level and take action to extend its life until you’re done with your day. It’s also recommended to carry a power bank just in case because you can never be too careful.
