How to Turn On Fast Charging on Samsung i939d Galaxy SIII (Blue)

Samsung i939d Galaxy SIII (Blue)

Fast charging — is a new technology that manufacturers have been actively introducing into their smartphones, tablets, and Bluetooth devices since 2020. What's the point? Previously, the speed was limited to standard 5 V chargers, but now there are models with power up to 20 V. The latter type of device can work in either slow or fast mode, depending on the chosen protocol. Because of the particular protocol, turning on fast charging in advance on Samsung i939d Galaxy SIII (Blue) is necessary.

Checking compatibility

The most main point — your smartphone must be compatible with the new feature. Going back to the topic of special protocols, what do you think will happen if your phone is plugged into a 100V charger? The answer — nothing. Your smartphone will only ask for 5V. And it is these values that the charger will give out.

As a consequence, your phone must have a special protocol pre-installed that allows you to request more power. And this is not available on all devices. Here's a brief list of the major manufacturers who have created their protocols for the new feature: Apple, Samsung, Xiaomi (Redmi, Poco, Realme), Oppo (OnePlus), Qualcomm, and Huawei (Honor).

Also, this function must support the charger and cable. With the first it is easy, if the power is more than 20V, then with 99% probability the device supports the function. By the way, due to the presence of special protocols, should not use non-original charging (such as a model from Xiaomi for Apple devices).

The cable is more complicated. The standard versions carry 2 А, and for fast charging need about 5 А (can do more). Manufacturers usually attach such models to their chargers, but if you lose it, then there are two options:

  1. Buy Chinese analog. We would not advise doing this because there is a high chance of running into a product with inappropriate characteristics. And if you're lucky, there's a high chance of getting a low-quality cable that will burn out after a couple of uses.
  2. Buy the original cable at official stores.

Turning on the function in the settings

If all devices are compatible, then we perform a small algorithm:

  1. «Settings» - «Device care».

  2. «Battery».
  3. «Settings».
  4. Turn the toggle switch to the position «On».

Frequently Asked Questions (FAQ)

Does this function kill the smartphone battery?

— No, because the battery life is affected only by the number of cycles «full discharge — full charge».

How much faster does the phone charge when this feature is on?

— It all depends on the protocol and the power of the charger. Apple smartphones charge about three times faster.

Is it possible to get a function on a device that does not support it?

— By legal means — no. In theory, if you are aware of what you are doing, you can flash the device and install the required protocols in it. If you are going to do this in your right mind, take care of a fire extinguisher beforehand, since after connecting the stitched phone to the charger, the USB port may sparkle.

Is it possible to connect fast charging to the phone without a special protocol?

— Yes, in this case, nothing will happen, because the charger will work in slow mode.
