Why is My Phone so Slow

Reasons for Slow Phones

You must have asked yourself and others many times why is my phone slow? Here’s the answer to that question:

#1) Background Apps

Talking about myself, one of the primary reasons my phone is slow often is because I don’t close my apps. They keep running in the background, resulting in the phone running slowly.

Over time, we often accumulate a lot of apps, most of which we often don’t use and forget about. Most of them run in the background, updating themselves, refreshing their data, etc., for when it is needed.

The phones currently have limited resources in the form of RAM and CPU and are split between all apps – high-priority tasks and background apps. So, the more apps running in the background, the fewer resources it will have to dedicate to the functions you need. This will slow your phone down.

What can you do?

Close all apps and uninstall the ones you don’t use.

Tap on the square icon at the bottom of your phone screen. All the open apps will pop up. Tap the close button at the bottom to close those apps.

Click on Uninstall and tap on the apps you want to remove from your phone. Once the app is installed, restart your phone and your phone should be working at a better speed.

#2) Full Storage

When the internal storage memory of your phone fills up, its performance starts lagging. It could be because of your accumulation of apps, undeleted photos and videos, uncleared caches, etc. Usually, phones display notifications once your phone starts running out of memory, asking you to clear some space by deleting unused files and media.

You can take the long road and manually search for the apps, files, videos, and photos you don’t want on your phone and delete them. Or you can use a phone cleaner. It will help you delete files, apps, and photos effortlessly. You can also transfer the data to an external drive or cloud storage.

#3) The Age of Your Battery

The Age of Your Battery

One of the drawbacks of portable electronic devices is that their batter age as well. The electrode films build up in them and that increases the internal resistance within them. This can affect your phone’s performance.

It can cause your phone to heat up. Since CPUs are temperature sensitive, the power management controller will reduce the speed of the processor. The old battery cannot provide a stable voltage or required current. This means the power controller will further reduce the speed of your phone or risk errors in execution.

In simple terms, an unstable power supply makes it hard for the CPUs to keep up their highest speed and it is just as troublesome for RAM and ROM as well. The resolution to this problem is changing the battery. However, phones today come with a sealed battery, and changing them could be extremely expensive. So, you will have to buy a new phone.

#4) Failing Phone Memory

Over time, the phone’s RAM and flash memory start to fail as well. Over time, their oxide layer deteriorates, thus slowing down your phone. The life of your phone’s memory largely depends on how much data you save. Once the memory starts to become redundant, there’s nothing you can do but repair or change your phone.

#5) Pending Updates

You should update your OS as and when they arrive. You can check your phone for updates.

Follow these steps:

  • Go to your phone settings.
  • Tap on About Phone.
  • Tap again on your phone’s version.

Phone version

  • Tap on check for updates.

Usually, when there’s an update, your phone prompts you to apply them. If you haven’t updated it in a while, checking it will make sure you haven’t missed any. Also, check the System app updater to see if any of your apps are pending updates.

On an iPhone, go to settings, select general and tap on software update. You can turn on automatic updates in both Android and iOS, so your phone can automatically update itself at a certain time.
