Android Phone Hardware Components

The most common issues when it comes to phones becoming slow is hardware related. It’s a broad issue that’s usually easy to determine what causes it. Although, hardware related issues can be determined as follows:

  • Slow Responsiveness – A noticeable lag in device performance. When you tap on an app or scroll to browse a page, a delay in device response is noticeable.
  • Sluggish Performance – The overall device experience is unpleasantly slow with performance hiccups and lags all around.
  • Device UI Lag – A noticeable UI delay between the action of the user and the reaction of the device.
  • Low-End Hardware – Phones that are within the budget or entry-level category. These phones possess the slowest hardware performance available on the market.

If you are experiencing any of the above, then it is likely that the reason for your phone suddenly slowing down is hardware related. If so, here are a few things that you can do.

1. Insufficient Storage (ROM) – Internal Storage

It is an undeniable fact that Android utilizes every storage available within the device.

This includes Internal Storage (ROM), Memory Storage (RAM), and External Storage (SD Card) as well.

Therefore, one of the common culprits when your phone suddenly becomes so slow compared to how it was before is insufficient internal storage.

When your phone is short on internal storage, it will start using its secondary memory (RAM) or external storage (SD Card). If this happens, your phone will then start switching between primary and secondary storages to run various programs and processes which then results in a drastic performance slow down on your phone’s operating times.

How To Free Up Internal Phone Storage Space?

To prevent this from happening, you can do either of the following:

  • Make sure that your phone would at least have 500 MB available space at all times.
  • Use Cleaning Apps to clean your internal storage of unnecessary files.
  • Uninstall Apps that you’re not using anymore.
  • Transfer and backup pictures, videos, or any form of media to your computer’s HDD or to your cloud services or to your personal home cloud if you have one.
  • Clear “App Cache” on the device settings.
  • Clear “Cached Data” through your device Storage settings or use your phone’s built-in storage cleaner.

2. Insufficient Memory (RAM)

Phone RAM is probably the least component that would affect your Android phone’s performance. Basically, a smartphone will still function without a RAM and this memory module is only used by Apps.

If the RAM of your phone gets full, the Android OS of your phone will then eliminate any unnecessary apps running at the background to make space for your most used apps.

Mainly used by both OS and application software, Android phones that come with bigger RAM capacity can run more complex software and multiple applications at the same time.

The only issue that you will suffer from if your phone’s RAM is low are:

  • Random app crash.
  • Laggy app performance.
  • Phone fully closes an app running at the background when opening another app.

How To Free Up Phone RAM Space?

The fastest way to free up your Android phone’s RAM is by restarting your phone. Other than that, you can do either of the following:

How To Increase RAM on Phone?

If you want to increase the RAM of your phone, the only way to do it is to replace the memory module soldered inside the motherboard of your phone with a higher capacity and identical socket memory module.

Other than that, there are no other means to increase the RAM of your phone.

And yes, you cannot download RAM on the internet to increase your phone’s RAM.

3. Dying Phone Batteries

Another hardware issue that can greatly contribute to your phone’s sluggish performance is a dying battery.

If you ever noticed, experienced, or encountered a time where your phone dies all of a sudden for no apparent reason, it is likely that the culprit is your phone’s battery.

Batteries have a certain life span and specific amount where you can charge and discharge it.

Once you’re approaching that limit, your phone’s battery will start to exhibit some unwanted behaviors such as being drained too fast, suddenly becomes bloated, and unable to provide enough power to your phone.

When your phone’s battery is about to die soon, one of the first symptoms that you might experience is your phone suddenly shutting off instantaneously.

This means that the battery cannot store and provide sufficient power to your phone anymore.

Why is My Phone Battery Draining So Fast?

There are 2 possible reasons why your phone battery gets drained so fast.

First is the way you use your phone. Heavily playing games on your phone can drain the battery fast. The second reason is a dying battery.

A battery that drains fast from casually using your phone is a dying battery.

How To Fix Phone Battery Draining So Fast?

If your phone has an irremovable battery, the only way for you to get it fixed is either bringing it to a service center or using tools to pry open your phone and replace it manually yourself.

You can then either buy the appropriate battery for your phone either from Amazon or from AliExpress.

4. Entry-Level Phones – Low-End Hardware Components

If you have a brand new phone that you bought for a cheap price, chances are, it also comes with cheap components.

Meaning, the components inside the phone are low-end and doesn’t pack the processing power. Using the phone alone already exhibits a sluggish and laggy experience.

It will become even more prominent and unbearable if you try to play demanding mobile games with this kind of phones.

There’s really nothing much you can do if this is the case. All you can do now is to prevent the phone from getting worse by keeping the above issues in mind.


Speaking of low-end entry-level cheap Android phones, Google created an OS called “Android Go” that’s designed to run on low-end smartphones.

Nokia 1 is a cheap Android phone that runs on a secure and up-to-date Android 8. 1 Oreo (Go Edition). It features a 4G LTE support along with Bluetooth 4.2 and a Headphone Jack.

We then highly recommend considering a gaming intended phone for your mobile gaming needs.

B. Slow Android Phone Performance – Software Related Causes

Android Modified OS – Bloatware

Have you experienced a time where your phone became slow after an update? Or a time you rooted your Android phone to remove bloatware apps to speed it up but it got worse instead?

When a phone slows down due to software issues, there are only 4 possible reasons for what causes it. Such issues would fall down to either bad phone update, bloatware apps, poor rooting procedure, or outdated OS.

  • Phone Update – A firmware or OS update are uncommon causes for a phone to become sluggish. However, Apple and Samsung were fined back in 2018 for slowing down phones with updates.
  • Bloatware Apps – Manufacturers and carriers often sell Android phones that come with their own pre-installed apps. These apps, whether they’re useful or not, tends to consume resources. Resulting in overall sluggish device responsiveness.
  • Outdated OS – Android phones run on older Android version become slow over time. This is due to the continuous update of various apps which then results in incompatibility issues and a slow down in the device performance.
  • Poor Android Phone Rooting – Using an Android Root Software to root your phone and install a custom ROM is a possible fix for the above issues. However, it can also worsen the condition of your phone if not done properly.

If you’ve just recently updated your phone, rooted your phone, or bought a brand new phone then it suddenly became slow, chances are, the slow down issue is likely software related. If that’s the case, here’s what you can do:

1. Android Phone Update – Firmware Update

If your phone became slow after an update, the manufacturer is to blame for releasing a poorly optimized update. If this is the case, here’s what you can do to possibly fix this issue.

How To Fix Phone Became Slow After An Update?

  • Perform a factory reset. Sometimes, things get messed up due to an update. This includes the current apps and configuration that you’ve done with the phone before the update. Factory resetting a phone could potentially fix this issue.
  • Root your Android phone and remove unnecessary bloatware apps. Usually, you can’t remove pre-installed apps. The only way to remove these apps is by rooting your phone. However, do keep in mind that rooting an Android phone comes with various risk.

2. Bloatware Apps – Uninstall or Disable Pre-Installed Apps

Pre-installed commercial apps that came with the phone tends to hog resources and slow down phones. However, the problem is that you can’t remove these apps.

To deal with this problem, you only have 2 options – either to disable or uninstall.

Basically, uninstalling involves removing the apps from your device. This is the best way to ensure that these apps won’t be a bother.

Disabling, on the other hand, is much more risk-free. Disabling ensures that these apps will not consume RAM space by running in the background.

However, it also means that the apps are still there and are consuming internal storage space.

How To Remove Bloatware Apps?

  • If removing the bloatware apps is your choice, the only way to do this is by rooting your Android phone. Otherwise, you won’t be able to remove them.
  • Once your phone is rooted, you can simply go to your App settings and uninstall them.

How To Disable Bloatware Apps?

  • If you won’t risk with rooting, then disabling these apps is your only choice. To do this, simply go to your Apps setting UI. Look for the apps and tap on them. You will then be prompted to the App setting UI and you will find “Disable” there.

3. Outdated Android OS – Older Android Versions (End-Of-Life)

Another possible reason behind the slow down of your Android phone is the end support for your phone’s Android OS.

Android Operating Systems typically has 18 months of support before Google cuts it and release a newer version.

For this reason alone, it will gradually slow down any phone that comes with the older Android OS and has reached End-Of-Life (EOL) support.

The everyday apps that we use are being updated to support the latest Android and because of this, the compatibility for older version becomes an issue.

If this is the case, there are not many fixes for this. Your only option is to root your Android phone and install custom ROMs.

4. Poorly Rooted Android Phone

Rooting an Android phone is definitely one of the fixes for the number 3 issue. However, if you not done properly, it could result in an even worse scenario.

It could render your phone useless or brick it, meaning, permanently making it useless or simply one big paperweight.

So, make sure to read and equip yourself with proper knowledge before attempting to root your phone.
