How does fast phone charging work?

Charge your phone faster - these tricks will help

The battery of your cell phone is running out and you urgently need to go to an important meeting or catch a train? Now is the time to waste no time. With a few little tricks you can charge your phone faster. You can read everything about it here.

The current flagship models of the smartphone manufacturers convince with ever larger battery capacity and mileage. Fast charging of the giant batteries is just as important. Here we show you how you can charge your mobile phone faster.

Charge your phone faster

Turn off the cell phone: Your mobile phone charges faster if it is not used in parallel while charging. In this way, it can fully concentrate on charging and does not use energy directly during the charging process. It is even more efficient when flight mode is activated, and the fastest way to charge the battery is when the smartphone is completely switched off.

Use the original power supply: In the best case, you should always use the original charging cable from your manufacturer and the corresponding fast charging power supply. Depending on the manufacturer, different fast charging technologies are sometimes used, so you should always make sure that the power supply unit and smartphone are compatible. The higher the wattage of the charger, the faster the charging process. In some cases you can also purchase a more powerful fast-charging power supply unit from the manufacturer.

Charge with cable: In addition to the wired version, some smartphones can also be charged wirelessly. If you want it to be quick, use cable and power supply charging, as wireless charging is currently a little slower. With the same wattage, however, the differences are only very small.

Save battery: Smartphone batteries lose their capacity over time. So that this is delayed as long as possible, you should save the battery. It is ideal if the battery level is always between 30 and 80 percent. You should also not leave the phone hanging on the charging cable all the time. By using the quick charge function, the battery power is also stressed more. If you have enough time, occasionally use slower charging to save your battery. You can deactivate the fast charging function on Android devices as follows:

  1. Open the settings.
  2. Scroll to the menu item Device maintenance.
  3. Tap battery pack and then on Charge.
  4. Slide the slider next to Quick Charge to the left to turn it off.

Fast charging does not harm the phone

Contrary to the assumption, fast charging does not harm your smartphone. At the beginning of the fast charging process, a full charge is used, but then the system recognizes that the battery is already largely charged and slows down the process to avoid damage to the battery.

Charge the cell phone battery correctly

Since the batteries of the newer smartphones are usually permanently installed and can therefore no longer be exchanged quickly and easily, you should charge your battery properly in order to benefit from it for as long as possible. If possible, never discharge the battery completely, but make sure to connect your mobile phone to the power when the remaining 20 to 30 percent is reached. The cell phone does not always have to be fully charged, a charge at around 80 percent is optimal. Always use the original accessories supplied by the manufacturer or a compatible and always high-quality charging cable for charging. Permanent storage of the smartphone in too warm (over 40 degrees) or too cold environments (below 5 degrees) can also lead to a deterioration in battery performance.

Fast charging technologies from smartphone manufacturers

Fast charging refers to all charging processes that fill a cell phone with more than 5 watts of charging power. As a rule, this power is between 15 and 40 watts. In recent years, manufacturers have developed various standards with which you can charge your cell phone faster.

Quick Charge

Quick Charge is the in-house charging technology of the chip manufacturer Qualcomm. At the beginning, this technology had a charging power of 9.45 watts, Quick Charge 2.0 was then already at 18 watts. This technology was initially used in almost all smartphones in recent years that have a Snapdragon processor installed. However, the manufacturers themselves decide whether this fast charging technology is activated. Samsung's Galaxy smartphones have also long been using the Quick Charge standard under the name Adaptive Fast Charging with a charging capacity of 10 to 15 watts.

USB Power Delivery (USB PD)

In the meantime, Quick Charge has been replaced by the new USB Power Delivery standard. The advantage of USB PD is that theoretically every manufacturer who uses a USB-C port can use the fast charging technology. USB PD is not limited to a specific wattage and is supported by almost all new smartphones.

VOOC (Voltage Open Loop Multi-Step Constant-Current Charging)

VOOC or SuperVOOC is the charging standard of OPPO and its subsidiary OnePlus. The special chargers and cables have a charging capacity of up to 25 watts and only work on compatible smartphones. Smartphones are 75 percent charged in 35 minutes, and VOOC technology takes around 70 minutes to fully charge. The SuperVOOC extension was used for the first time in the OPPO Find X. This means that the device can be charged from zero to one hundred in just 35 minutes.

There are also less well-known standards from smaller manufacturers such as Motorola TurboPower or Vivo Dual-Engine Fast Charging, also known as Mediatek PumpExpress.

Mi Super Charge Turbo

At the end of last year, the Chinese manufacturer Xiaomi presented a special fast charging system that claims to fully charge even large batteries of 4,000 mAh in just 17 minutes. A 100 watt power supply should make this record time possible. Since a few flaws still have to be corrected, the start of the new fast charging technology will still be a long time coming.
