The biggest problem smartphones facing over time is slow performance. Smartphone, when gets older and older, gets slower and becomes problematic and it is frustrating.

Why Smart Phone is slow?

Some of the reasons for the slow smartphone are as follows:

1 Hardware life

The hardware of smartphones is like the human body. When the human body after a certain age does not function properly and actively and started to retardate, the same happens in the case of hardware.

For example, the processor will give the best performance at a certain temperature and if the processor gets overheated with the raise of temperature then processor performance may degrade.

Also, excessive heat, cosmic rays, dust, electric spikes stress transistors and degrade the life of transistors and this may make your smartphone(Android or iPhone) fail entirely. This age failure in the transistor is binary ie. may or may not happens.

2 Damage / Loosen Hardware Parts

Smartphone hardware can get damaged after being dropped, crushed, liquid falling on it, power surges, forcing cables into wrong ports, etc. Even due to these actions, hardware parts may lead to loosening and cannot function properly.

3 System Upgrades and Updates

After using a new smartphone for a few months or years, you will get system updates and upgrades. System Updates and Upgrades are good for your system performance because on each update they are fixing various issues related to performance, security, usability, etc. but it actually increases memory size. So, ultimately system starts taking more operating capacity, consumes more power, and overloads the system, so finally, you will feel that system is not performing well.

If you have the latest phone and new updates appear then installing that may help boost performance. If you have an old phone and you are getting updates for it and you are installing it then you may face performance-related issues.

4 Installation of third party application

When you buy a smartphone, you will only have few applications provided as provided by it. In the process of using, you may need more applications so you continue installing applications. If you have more and more application then takes some space and may degrade the system. Also if the application is not coded properly and memory management is not properly then it may take more system uses than expected.

Note: In the case of the google play store, all the applications not developed by google are third party applications. They follow guidelines and criteria provided by google. Eg. of third party applications: Facebook, Twitter, Instagram,Tiktok etc

fig. Third-party apps

Any popular newer apps developed by developers love trying new technology targeting new brands of phones. So, these newer apps require more resources like CPU, RAM. So, if you install those apps in legacy smartphones then your phone will slow down.

There are two main mobile operating systems.
1) Android
2) iOS

If you download from play store and apple store, then in most of the case it is ok to install it. But there might be applications which are not properly coded and then installing those applications may slow down performance because of memory leakage problem. Also, stores do not guarantee those free apps are safe.

Also, Read SATA SSD vs NVMe SSD. Buy NVMe SSD if possible

Also, on the phone, you are able to install software outside from the play store/AppStore and they may contain various, ransomware, unnecessary ads that take your information and consume memory, and damage system performance badly. 

5 Background Process

Today normal phones have 30 to 40 apps installed on their devices. Among them many of them are running in the background even you are not using an active screen. This takes more of the system resources like CPU and RAM, battery. An example of those background apps are Social Media Apps, web browsers, email apps, etc.

6 Mobile Storage Fragmentation

Storage Fragmentation is one of the big causes for your smartphone(iPhone or Android) and computer to slow down.

We perform thousands of read/write operations to phone memory while using social media, play games, take notes, delete undelete photos, videos, and many more. If an improper write operation is performed then a fragmentation phenomenon occurs. Fragmentation is unused memory.

In the process of storing, if a large process arrives then they are split and are saved in various parts of the memory. And when retrieving that process then the memory has to cover more physical distance to retrieve the whole process and finally load it.

Fragmentation is an obvious case and not avoidable, and it will happen at every level from kernel level to application level.

7 Memory Degradation

OEM uses NAND flash memory because it is cheaper and faster. But these types of memory degrade themselves over time. The various factor of degradation are:

  •  How often do you use your phone?
  •  Task you perform on your phone (intensive task or normal task)
  •  Quality of Memory you have installed
  •  The magnitude of reading/write performs from/to memory.

8 Use of Live Wallpapers, and widgets

If you have a low-end processor and less battery mah then live wallpapers and widgets of very high resolutions can slow down your smartphone.

9 Little or No Internal Storage(ROM) Remaining

If there is no enough space to hold the data and application in your smartphone then it may cause the slow performance.

10 Insufficient RAM

If you have a phone with less RAM capacity then running heavy applications may slow down your phone.We know that today smartphones can perform multitasking jobs, if there is insufficient RAM then will able to perform one task at a time and halt other application.

11 Old Battery

The smartphone works on particular energy and if the battery cannot provide sufficient energy then the smartphone will not perform perfectly. If the battery cannot provide sufficient energy then your smartphone screen goes dimmer, shorter display-on time, etc. But it doesn't directly affect the performance of smartphones as does by the above point.

And if you buy a new but duplicate battery then this may affect your phone because lower cutoff voltage,high cutoff voltage of new may not match with duplicate one and the battery gets drain and swollen earlier than expected.

12 Too many applications opened

If you keep opening the application and using only one application is active then this may internally use memory.

How to troubleshoot a slow Phone?

You can troubleshoot/fix your slow phone with the following solutions.

1 First Know your Device

You the owner of the phone only know the capacity of your phone. So, wisely use it.

2 Remove Unused Applications

First, identify which application you are not using. Some unused applications keep taking your resource in the background so it's better to remove/uninstall those unused applications. It helps to free up the used resources.

3 Clear Software Cached Data

If your system is slow then you can clear software cache data and temporary files. Some applications like Facebook, messenger, youtube, browsers cache your data in many megabytes. You can clear those application cache data to improve your phone performance.

4 Software Updates

Actually, software updates are critical for your phone and recommend doing updates. Read what is provided in the updates and update accordingly. Security-related updates, bug fixing, performance updates, etc are necessary, and do it. 

5 Close unused applications

Close unused application which you are not actively using.

6 Hardware Maintainance

If any problem occurs like dropped mobile in water, damage some part by dropping on floor, etc. with your phone, then it is better to take that to a mobile mechanic and protect your system from being even worse.

7 Disable Transitions and Animations

It is better to disable live wallpapers and widgets from your phone.

8 Stop Auto Synchronization

9 Disable Background Processes 

10 Stop some features when you do not use Bluetooth.

11 Check Battery Condition

12 Use high-speed SD Card 

13 Restart Phone

Sometimes restarting your phone solves the problem.

14 Factory Reset
