If your Android is a few years old and starting to feel sluggish, it doesn’t mean you have to rush out and buy the newest flagship model. Thanks to longer software support from brands like Google and Samsung, older models can still run smoothly, as long as you give them a little attention. 

Before you start shopping for a replacement, try a few simple adjustments. You might be surprised by how much faster your phone feels once you clear out unused apps, optimize battery use and turn off background drains.

Whether you use a Samsung Galaxy, Motorola or OnePlus phone, chances are you can still improve battery life and overall speed without buying something new. Just remember that Android settings vary slightly from brand to brand, so the menus may look a little different depending on your phone.

Settings to improve your battery life

Living with a phone that has poor battery life can be infuriating, but there are some steps you can take to maximize each charge right from the very beginning:

1. Turn off auto screen brightness or adaptive brightness and set the brightness level slider to under 50%

The brighter your screen, the more battery power it uses. 

To get to the setting, pull down the shortcut menu from the top of the screen and adjust the slider, if it’s there. Some phones may have a toggle for auto brightness in the shortcut panel; otherwise, you need to open the settings app and search for «brightness» to find the setting and turn it off.

2. Use Adaptive Battery and Battery Optimization

These features focus on learning how you use your phone, including which apps you use and when, and then optimizing the apps and the amount of battery they use. 

Some Android phones have a dedicated Battery section in the Settings app, while other phones (looking at you, Samsung) bury these settings. It’s a little different for each phone. I recommend opening your settings and searching for «battery» to find the right screen. Your phone may also have an adaptive charging setting that can monitor how quickly your phone battery charges overnight to preserve its health.

Why you should use dark mode more often

Another way to improve battery life while also helping save your eyes is to use Android’s dedicated dark mode. Any Android phone running Android 10 or newer will have a dedicated dark mode option. 

According to Google, dark mode not only reduces the strain that smartphone displays cause on our eyes but also improves battery life because it takes less power to display dark backgrounds on OLED displays (used in most flagship phones) than a white background. 

Depending on which version of Android your phone is running, and what company made your phone, you may have to dig around the settings app to find a dark mode. If your phone runs Android 10 or newer, you’ll be able to turn on system-wide dark mode. If it runs Android 9, don’t despair. Plenty of apps have their own dark mode option in the settings that you can use, whether or not you have Android 10. 

To turn it on dark mode, open the Settings app and search for Dark Mode, Dark Theme or even Night Mode (as Samsung likes to call it). I suggest using dark mode all the time, but if you’re not sure, you can always set dark mode to automatically turn on based on a schedule, say from 7 p.m. to 7 a.m. every day, or allow it to automatically switch based on your location at sunset and sunrise. 

Keep your home screen free of clutter

Planning to hit up the Google Play Store for a bunch of new Android apps? Be prepared for a lot of icon clutter on your home screen, which is where shortcuts land every time you install something.

If you don’t want that, there’s a simple way out of this: Long-press on an empty area of your home screen and tap Settings. Find the option labeled something along the lines of Add icon to Home Screen or Add new apps to Home Screen and turn it off. 

Presto! No more icons on the home screen when you install new apps. You can still add shortcuts by dragging an app’s icon out of the app drawer, but they won’t appear on your home screen unless you want them to.

Set up Do Not Disturb so that you can better focus

If your phone routinely spends the night on your nightstand, you probably don’t want it beeping or buzzing every time there’s a call, message or Facebook alert — especially when you’re trying to sleep. Android offers a Do Not Disturb mode that will keep the phone more or less silent during designated hours. On some phones, this is referred to as the Downtime setting or even Quiet Time.

Head to Settings > Sounds (or Notifications), then look for Do Not Disturb or a similar name. If you can’t find it, search for it using the built-in search feature in your settings.

Using the feature, you can set up a range of hours when you want to turn off the digital noise. Don’t worry, any notifications you get while Do Not Disturb is turned on will still be waiting for you when you wake up. Also, you can typically make an exception that allows repeat callers and favorite contacts’ calls to go through. Turn that on. If someone is calling you in an emergency, odds are they are going to keep trying.

Always be prepared in case you lose your phone or it’s stolen

Is there anything worse than a lost or stolen phone? Only the knowledge that you could have tracked it down if you had turned on Google’s Find My Device feature.

To prepare for a successful recovery, here’s what you need to do: Open the Settings app and then search for Find My Device. It’s usually in the Security section of the Settings app.

If you have a Samsung device, you can use Samsung’s Find My Mobile service, which is found in Settings > Biometrics and security > Find My Mobile. 

Once that’s enabled, you can head to android.com/find from any PC or mobile device and sign in to your account. Samsung users can visit findmymobile.samsung.com to find a lost phone. 

If you have trouble setting any of this up, be sure to read our complete guide to finding a lost Android phone.

Assuming your phone is on and online, you should be able to see its location on a map. From there, you can make it ring, lock it, set a lock screen note to tell whoever has it how to get it back to you, or, worst-case scenario, remotely wipe the whole thing.

And always keep your phone up to date

As obvious as it may seem, a simple software update could fix bugs and other issues slowing down your Android device. 

Before you download and install the latest software update, make sure your device is connected to Wi-Fi, or else this won’t work.

Now, open the Settings application and type in Update. You’ll then either see Software update or System update — choose either one. Then just download the software, wait for a few minutes and install it when it’s ready. Your Android device will reboot and install the latest software update available.
