How to make 4G and 5G faster on Android and iPhone

If you want to know the steps on how to make 4G and 5G faster on Android and iPhone then check this post.

Faster internet speed is a primary requirement for people, and to achieve that, people upgrade phones every year.

4G LTE and recently 5G has changed the way that people communicate.

Smartphones are now the primary means of communication and with fast internet, people can keep track of all things happening around.

How to make 4G and 5G faster on Android and iPhone

Still this is not perfect, in some cases we notice a drop in internet in certain places causing the communication to break.

It becomes frustrating when we use our phones to stream content on the go. When the speed reduces, the content starts buffering.

There are various steps that you can follow to boost 4G and 5G speeds in Android and iPhone.

Before jumping into the steps for improving your 4G and 5G speeds, we need to know the reasons of speed reduction.

Why is my 4G and 5G so slow?

Primary reasons for slow network speed in 4G and 5G are the following

Congestion in network

4G being used by billions of users can create congestion in a specific area.

5G could solve this issue but still when a lot of people connect to the same tower, it could cause reduction in network speeds.

4G is a tried and tested network and in areas where billions of users have the same network provider connection, the network is needed to be split within all of them.

This could cause the speed of the internet to be shared.

When it comes to 5G, for now we have better speeds as it’s a new technology and there are not many phones that support 5G.

As the technology becomes common and more people get 5G phones, even 5G would have speed issues.

5G network would be definitely better in terms of speeds but when you consider range, 5G network would have some limitations.

It is a costlier technology due to the need of multiple towers in a short distance. 4G was better in this case because it needs only less number of towers.

Barriers and obstruction between the tower and the device

Another major cause of drop in 4G and 5G network is due to the number of building and trees in your area.

If you are living in a city, then you will be surrounded by multiple buildings and walls. This could weaken your signal before reaching your phone.

It could be reason for slow internet that you are receiving.

4G signal is better when it comes to wall penetration, but 5G is not that great with it.

So in western countries, multiple towers are placed in short ranges to get a better signal reception

In India, we use mm wave for 5G which support a longer range, still there could be issues with locations that have many users in a small area.

Issues with network provider

When it comes to slowness in 4G and 5G speeds, the major role is played by the network provider.

The network provider should be able to deliver quality 4G and 5G network signal. And also the hardware used for network should be good enough to support high demand.

Speed of the network is determined by the quality of hardware used in towers by the network provider.

When it comes to 4G and 5G services in India, there are two major network providers, Jio and Airtel.

Both have come up with their versions of 5G recently and presently the network coverage is being expanded throughout the country.

Smartphone in use

The final and the most important thing is the smartphone that you have in your hand. Based on the processor and the network modem built in your smartphone, the network reception may vary.

When it comes to Android phones with 4G and 5G, they usually have Snapdragon processor which support the 5G network.

In iPhone, Apple’s in house process the A14 or A15 supports 4G and 5G networks.

Apple earlier was using Intel modems, which had issues with network reception. Recently they have switched modems to Snapdragon, making the reception to improve.

Another thing to consider is the processor. Your phone processor should be able to handle the network speeds and also render content accordingly.

If the processor in your phone is slow, then your video and streamed content could lag.

Now we know some basic issues that could cause slowness in 4G and 5G in Android and iPhones.

How to make 4G and 5G faster on Android and iPhone

Let’s now check though some ways to improve the 4G and 5G speeds in Android and iPhone

Restart Android phone
  • Wait for a few seconds.
  • Your phone would turn off completely.
  • Long press the power button for some time.
  • The phone should boot up.

After the phone has completely booted up, turn on the 4G or 5G network and check for the network speed using the speedtest app.

Upgrade to the latest Android version

As Google and other Android phone manufactures, release regular updates for their version of Android, it’s good to keep your phone Android version up to date.

Update Android phone

There could be bugs in the previous versions that could affect the network speed.

Read the update log and update the version of Android to fix any issues which could help in improving the 4G or 5G network speeds.

Clearing the App cache and System Cache

Cache files build up is another main reason for lag in phone and 4G or 5G network speeds.

Unwanted resources run in the background due to this sipping the data in the background.

This could cause reduction in bandwidth for the apps that you are using, causing delays and buffering.

To avoid this, we need to clear the cache memory of each app and also the entire android phone.

clear cache in Android phone

Clearing the cache of each app is easy by going to Settings > Apps > Storage > Clear cache and Clear data.

If you want to clear the cache of the entire phone, you can do it by going to recovery mode.

Each phone as a different way to do it. In general, we can do it with the following steps.

  • Turn off the phone
  • Reboot the phone by pressing volume down and power button for some time.
  • The phone with turn on to recovery mode.
  • Here you will find an option to clear cache of the phone.
Note: If you clear data using this method, All the apps would reset to their default state.

Uninstall or disable unused apps

Another simple step that you can follow is to uninstall or disable an unused app.

In some cases, we download a specific app for one time use and forget it.

The app remains in the background and uses the data. This may cause sharing of bandwidth, ultimately reducing the network speed.

The easiest way to handle this issue is to go to setting and apps.

Select the app and uninstall it.

Using a network speed booster

With the use of a network booster app like Net Optimizer : Optimize Ping, you can easily boost your 4G and 5G speeds in Android.
