How to Enable or Disable the Fast Charging on Galaxy S21, S20, S10, S9, Note

You may want to disable the fast cable charging to make you battery live longer. If you didn’t know, the faster the battery is charged, the less cycles it can withstand.

That’s why we highly recommend that you turn it off when you don’t hurry and have enough time to charge the battery using a lower current. This will extend the life span of your built-in battery and you will have to replace it much later.

Fast cable charging is enabled by default. But if you disabled it and forgot where that setting is this guide will help you as well.

Wrapping Up

That’s it. Turn on the fast charging only when you really need it. For instance, when you came home to change clothes and you know that you will leave for a meeting in half an hour, then it is appropriate to turn on fast charging so that the phone can replenish energy as quickly as possible. But when you have unlimited time to charge your Galaxy’s battery we recommend to turn it off.

Have a nice day with your favorite Galaxy smartphone!

  1. Whilst I appreciate the ideology of higher current increasing wear and tear on batteries, I have had a Huawei p20 for nearly 2 years. It uses superfast charging, a feature I have enjoyed immensely. I have noticed no real problems with the battery. I have today upgraded to a S10+. The charge rate is lower. I will miss superfast speeds. But 15w is nothing to avoid when at all possible.
