What happens when you restart your phone?

Almost all of us, at some point in our life must have gotten the suggestion that goes something like this “turn off and restart your phone”. Am I right? The majority of us have had this recommended to us, any trouble in your device and the first thing that comes to our minds is to restart the phone. And most of the time the problem does go away once we restart our phones. Well, this is no magic that miraculously cures every problem that arises in our phones just by restarting our smartphones. There is logic and science behind it. We will cover “what happens when you restart your phone” in this article.

The reason-RAM: It makes a lot happens after phone restart

Well, the primary reason for there being issues in your device and you have to restart stems from RAM usage. When the RAM usage increases then automatically the system slows down. Even with the latest softwares it is inevitable that at some point using multiple apps will take up more storage in RAM which in turn will slow it down, which will further lead you to restart your phone.

It is logically correct if someone says the more apps you use, the more RAM storage it occupies. Technically speaking the apps that run in the background take up RAM storage which in turn reduces the performance of your device.

Regardless if you keep removing the previously running apps, they do not erase or stop completely, they keep taking up storage space in RAM. Since there are apps that were previously running in RAM the operating system will obviously have to work harder, to put it simply, in order to start up new apps and also keep the previous ones running. This in turn creates the problem and slows down the entire system, it starts lagging and all kinds of stuff like that. Which ultimately leads us to restart our phones.

What happens which helps when you restart your phone?

Restarting our phones is beneficial in this situation because when we restart our phones, all the data is erased, kind of like you beginning with a clean slate. When we restart our phones the apps that were previously running and the fragments of the previously running apps are all wiped clean. So RAM is as good as can be. This, therefore, increases and improves the performance of our devices.

Once the rebooting is done, your device is a bit quicker, it launches apps quickly, and you can switch from app to app rather faster than you could before rebooting. This mellow condition after rebooting your device can stay that way up to a few days, a week, or even multiple weeks. It is honestly quite variable. Every device and its operating system may differ, some are better at memory management while others are not. So being able to predict when or how frequently you must reboot your device is a little difficult.

If you are having difficulties with a specific app and closing and restarting the app is not helping then rebooting your device can be the way to go. Why must you think? As explained earlier even when we erase apps that were running there are fragments of it still remaining in the RAM. And to clear out the RAM in order to get it into the optimal condition we can restart our device which shall resume the proper functioning of your app. But if it does not, then we might be facing a bigger issue.

Though you must also keep it in mind that rebooting your device is not the only solution to get rid of the problems that you have been facing. It is also not necessary that after rebooting the problem will be solved. If there are a few minute problems then that might get resolved by rebooting but if it does not then it implies that you are facing a bigger issue. Even still giving it a shot is worth it because it might actually resolve the problem at hand.

Is it mandatory to reboot my device?

It is by no means mandatory to reboot your device. It is entirely up to you whether you want to reboot it or not. However if your phone faces regular glitches and slowdowns, you must reboot your device at least weekly, or however frequently you wish to do it.

There is no right or wrong answer to how often you should or should not reboot your device. 


Does restarting phones clear up the cache?

No, restarting or rebooting your phone will not clear up cache memory from your device. Restarting your phone just closes all the running apps, shuts down, and then turns back on. Rebooting is helpful in cases where any apps or software is acting up and once you restart the device it goes back to normal. 

What does a restart do to your phone?

Restarting your phone simply closes all the running apps, powers off, and then powers on again. The storage space occupied in RAM by the running apps and fragments of earlier apps is wiped clean. 

Will I lose my photos or videos if I reboot my phone?

No, you will not lose any of your data, be it photos, videos, songs, documents, or any other stuff. If you reboot your phone it only clears up the running apps, no harm comes in the way of your data. Your data will be as it is even after the completion of rebooting your device. 

Are restarting and rebooting the same thing?

Yes, restarting and rebooting are the same things. It simply means powering off and then powering on any device. 

Is restarting different from shutdown?

Yes, restarting is in fact different from a shutdown. On one hand, restarting will clear the RAM of the running files, and power off and then power on the device while this process consumes energy, shutting down a device means that the device goes into deep hibernation and is not using any source of energy whatsoever. Once you shut down your device there is absolutely no power consumption, while on the other hand restarting a device consumes power.
