If you own an old Android device How to Survive Using an Old Android Phone with No Internal Memory Using an ancient Android phone with barely any internal space is a huge pain. Here's how to survive and make the most of it. Read More , chances are it’s so slow you’re not using it. And if you do use it, its performance probably sucks. Here’s how to make an old Android device faster.


Get Rid of All the Garbage

Removing junk (i.e. apps, photos, and music files) is the number one way to speed up an Android device. After that, there are a few features you can enable or disable that make your phone or tablet slightly faster—but those are all secondary to cleaning out the clutter.

For a faster device, there are three categories of eliminating clutter:

  1. Finding and removing apps that you don’t use.
  2. Finding and removing apps that slow your system down.
  3. Optimizing your device for better performance.

Let’s look at each of these in turn.

1. Finding and Removing Apps You Don’t Use

Too many media files and apps can cause sluggishness. Your phone or tablet’s storage technology (solid state drives) performs poorly when almost completely filled.

But how do you clean up a cluttered drive? I recommend two apps: Files Go for beginners and the open source DiskUsage for advanced users.


Automatically Remove Clutter With Files Go

This method only works for Android 5.x and newer.

Files Go is a first-party app from Google. It works without much effort from the user. You simply install the app and then run each of its functions.

In order for Files Go to automatically free space, you must grant it usage access. To enable this, simply open Files Go and under Find unused apps, tap on Get Started.

Then go to Settings and tap the slider that enables usage access for Files Go.

After it runs its analysis, Files Go lets you know what apps you’re using and what media you can remove. Depending on your device, this could take a while, though.

Manually Remove Files and Apps With DiskUsage

DiskUsage runs a quick analysis on your tablet or phone’s storage drive and visualizes how much space remains. It also shows what files are taking up the most amount of space. I use the app to identify what media files (like music, photos, or apps) are taking up the most amount of space—and then I delete those files to speed up my phone.


DiskUsage Android

Do not use DiskUsage on any system storage drive. To delete a file using DiskUsage, open the visual depiction of your files and tap on the three dots in the upper-right corner of the screen. From the context menu, choose Delete.

2. Finding and Killing Misbehaving Apps

Android’s design allows for apps to run in the background without consuming processing power. In theory, a well-designed application only uses resources for brief periods of time. Unfortunately, poorly designed apps call on operating system services that can drain batteries and slow performance.

The solution is to find those misbehaving apps and remove them. Unfortunately, Google doesn’t make it obvious. Here are a few tips on how to find potentially bad apps.


Identify Auto-Starting Apps on Android 5.x and Newer

The simplest way to identify possible bad apps is by looking at their permissions 5 Smartphone App Permissions You Need to Check Today Android and iOS permissions can be abused in various ways. Don't let your phone leak data to advertisers. Here's how to take control of app permissions. Read More .

A quick primer on permissions: apps must request permission to use sensitive parts of your phone. For example, an SMS application needs to request the permission to send and receive text messages. If it wants to run all the time, it requires a permission called run at startup.

Unfortunately, Google doesn’t make it clear which apps run at startup.

To find it on Android versions 5 through 7, navigate to Settings > Apps. On Android 8 Oreo, you’ll find this at Settings > Apps & notifications > See all X apps. Here, tap on a non-system app that you suspect of causing problems. Then tap on Permissions.

From the Permissions menu, scroll down and scan through each permission. If you don’t see the entry for run at startup, then the app doesn’t run as soon as you boot your phone.

Android Run at Startup Permission

Unfortunately, you cannot disable this permission on most Android devices. While many autostarting apps are well-behaved, a number of them are not. However, in general, the fewer apps that autostart, the better.

Remember that a third-party ROM can grant access to features not found in normal Android versions. So if you’ve got an older device, you may want to consider a custom ROM.

Identify Auto-Starting Apps on Android 4.x

For Ice Cream Sandwich through KitKat devices, you can find autostarting apps by restarting (hold the power button down until you see the power off or restart options) and then heading to Settings > Apps. Here, swipe from the right side of the screen to the left side to open the Running tab.

Android Running Apps

These are the apps that start with your device and run continuously in the background. Some of these are system applications, meaning they perform some function that is essential to Android’s operation. The others are apps that you’ve installed that are always in memory and sometimes consuming processing resources.

Identify Auto-Starting Apps With Startup Manager

Fortunately, there’s an app for this as well. Startup Manager [No Longer Available] allows you to identify and eliminate apps that automatically start along with your phone—without costing a dime.

The app is simple to use. After installing and opening the app, you’ll see all the apps that automatically start along with your device. If you spot an application that you do not need, you can remove or disable the app by long-pressing (touching and holding) until a context menu appears.

We don’t recommend keeping any app that you do not use—even if it doesn’t autostart. And we certainly don’t recommend keeping Startup Manager on your device. The developer has abandoned it, and it has too many advertisements.

Android Startup Manager

A word of caution: if you use Startup Manager to disable system apps, you will have to factory reset your phone to get it working again. System apps are critical to the function of your phone and should never be disabled unless you know what you’re doing.

Note: Startup Manager was rolled into a larger toolkit of Android optimization apps called All-In-One Toolbox. You can do the same thing with fewer bugs on that version. However, it may not support older phones. And it has far too many advertisements for me to recommend installing it.

Turn On Manual Sync for Apps

After eliminating all non-essential applications, you need to turn on manual sync for each remaining app so it doesn’t update all the time. If you absolutely need push notifications for an app, feel free to leave notifications on—but keep in mind that the effect of dozens of apps with sync turned on is cumulative.

Newer hardware may not even blink at tremendous amounts of apps constantly updating. Older hardware may choke on it.

3. Optimizing Your Device

Some of the optimization tips in this tutorial require enabling Developer Options (see below). The rest only require a few simple actions to initiate.

Trim and Optimize Your Storage Drive

This method only works for Android 4.3 and newer.

Unfortunately, even after killing the clutter, Android may still feel sluggish. That’s because of the way flash storage works. Solid state memory doesn’t automatically optimize itself immediately after freeing up space on your device.

For Android version 4.3 and newer, a process called trim needs to run before the storage starts behaving normally again. Trim works best when you have at least 25 percent free space. And you may want to leave the phone charging overnight in order for trim to run uninterrupted.

Android Enable Airplane Mode

To optimize the storage on your device:

  1. Make sure you have at least 25 percent free space on your phone or tablet.
  2. Put the phone in Airplane Mode by swiping down from the notifications tray and tapping on the airplane icon.
  3. Plug it into a power source and leave it charging overnight—24 hours for the best results.

External Storage

If your Android device includes a microSD card slot, it’s possible to enable write-caching and move apps to the card. Unfortunately, most microSD cards are pretty slow and can contribute to poorer performance. You actually need a Samsung Select or EVO card or an A1-rated card in order to get better performance.

Enable Developer Options

This method only works for Android 4.4 and newer.

A handful of performance optimization tips require turning on Android’s Developer Options. Turning on Developer Options opens the door to other tricks, like disabling animations, that lead to faster app launches and more.

We’ve previously covered how to enable Android’s Developer Options The 14 Best Android Developer Options Worth Tweaking Here are the best and most useful developer options in Android, including disabling absolute volume and much more. Read More . Just perform the following:

  1. Open Settings.
  2. Scroll down the list and choose About Phone.
  3. Locate Build number and tap on it seven times.
  4. You should receive a notification that you’re now a developer. From now on, you’ll see Developer Options in your Settings menu (located near the bottom).

After enabling Developer Options, head back to your Settings menu and tap on Developer Options. Within this section, there are a few features you can tweak that improve performance.

Turn Off Animations

Android automatically animates all screen transitions. So for example, whenever you open an application, an animation plays. Turning off animations improves how fast apps launch.

Android Turn Animations Off

To turn off animations, first, open Developer Options. Scroll down the list of items and locate the entry for Drawing. Under this, you should see three kinds of animations:

  • Window animation scale
  • Transition animation scale
  • Animator duration scale

The animations can scale between off and 10x. Switch them off by tapping the entry and selecting off from the context menu.

Force 2D GPU Rendering

Some apps use your device’s CPU, rather than the dedicated graphics (GPU), in order to run 2D games. This can result in poorer performance. Enabling this feature can sometimes improve performance by forcing games to use the GPU (if they don’t by default).

But the tradeoff can decreased battery life, and sometimes worse stability. I’ve enabled it on a few older handsets and haven’t noticed any issues with games such as Kingdom Rush. (But I’m pretty sure that game properly uses the GPU.)

Android Force 2D GPU Rendering

To find this, navigate to Developer Options and locate the option under the heading Enable hardware accelerated rendering. Then tap on the slider to enable it. However, not all phones include this option.

Force 4x MSAA

This tip doesn’t improve performance, but it does make games look better. If you play games on your Android device and always leave it plugged in—or don’t care about battery life—consider enabling Force 4x MSAA. The feature smoothes out jagged corners on some games. On the downside, it can decrease your battery life and the apps can sometimes (but not always) run slower.

To enable it, navigate to Developer Options. Then tap on the slider next to Force 4x MSAA to enable it.

Look at Process Stats

This method only works for Android 4.4 and newer.

Another method for finding bad apps is through looking at a feature called Process Stats. To find Process Stats, navigate to Developer Options and scroll down to Process Stats. In this section, you can look at exactly how long a process (or application) has run in the background and how much memory it consumes.

Android Process Stats

Not every app here is bad for your device’s performance. However, you might spot a few apps that you know you installed and never use. In that case, uninstall these applications.

Can You Speed Up an Old Android Phone or Tablet?

Yes! For the most part, the most powerful method for improving performance is to remove bad apps. After cleaning your device up, I also recommend putting it into airplane mode and leaving it charging overnight. And to get a little more performance, try turning off animations.

Unfortunately, even with all the right tweaks, Android doesn’t age well. And that’s the big issue with older devices: security.

Believe it or not, you really don’t need a malware scanner app. And whatever you do, certainly don’t install a task killer or RAM booster.

MakeUseOf has covered—in detail—many Android optimization tips. It’s true that most Android speed hacks are myths and don’t really improve anything. However, a few tips really do supercharge Android’s performance How to Make Android Faster: What Works and What Doesn't If your Android device doesn't feel as fast as it once was, try these tweaks to get it running faster (plus common "tips" to avoid).
