Enabling and disabling the fast charge function in your phone

Fast charge is convenient for most users, because your phone no longer needs to be connected to the source of power (e.g. a socket) for a longer period. Some mobile phone users decide to switch off the fast charge function, because they fear for the battery. Such fears are usually unfounded. But if you still want to switch off the fast charge function or switch it back on after a while, this post will show you how.

In this article you will find out:

how to switch off the fast charge function in your phone,
in which models you can switch on the fast charge function,
whether or not fast charging affects battery life.

What is fast charge?

Fast charge is a function developed in response to the users’ demands, as phone batteries come with an increasing capacity. The bigger the battery, the longer it needs to recharge. Plus, we often use our phones not only for making calls, but for a variety of other things as well – all this is reflected in a shorter battery life. That’s why new chargers were launched, which can recharge your phone much faster.

What you have to remember, though, is that not all phone models come with the fast charge option (i.e. Fast Charge or Quick Charge). Below we will explain how to switch this function on or off, depending on the model.

Fast charging shortens battery life – true or false?

Some say fast charging may damage the battery. It’s not true, and in order to prove it, it’s good to explore how fast charging really works. In this technology, the battery is charged faster only for some time. When the battery is 70% full, the phone switches back to the normal (slower) charging mode. This is to prevent accidents (such as overheating). If fast charging were to damage your phone, the charger would have to provide higher amperage all the time, until the battery is fully charged. And this is not so – as we mentioned, fast charging is switched off at 70%. So if you have a properly chosen high-quality charger, you can enjoy all the benefits of fast charging without having to worry about battery damage.

Summary – personal settings

In modern phones you can select the charging mode yourself (e.g. by choosing wireless charging, using a power bank or a standard USB charger. What is more, you can choose for your phone to be charged at a standard charging or much faster, if you opt for the relevant solution.
