Fast Charging on Android, and how to Charge your Phone Faster

Fast charging on Android, and how to charge your hone faster

How does fast charging on Android work?

Fast charging on Android is a feature that allows you to charge your phone’s battery faster than the standard rate. It works by increasing the amount of power that is delivered to the battery through the charger and cable. However, fast charging is not as simple as using a higher-wattage power brick. There are different types of fast charging standards that are compatible with different phones and chargers. You also need to consider the way that the battery receives power and how it affects its long-term health.

To understand how fast charging works, you need to know some basic concepts about batteries and electricity. A battery has a specific voltage and can input and output a certain amount of current. More of both means more power, and therefore faster charging. However, batteries have very strict operating limits, particularly regarding voltage, that must be followed in order to charge them safely.

Battery charging is broken down into two distinct phases: constant current and constant voltage. In the constant current phase, the voltage increases towards its peak, while the current stays constant at a high level. This is the phase where fast charging technologies pump as much current as possible into the battery before it reaches its peak voltage. In the constant voltage phase, the voltage has reached its peak and the current drops down. This is the phase where the battery is almost full and the charging speed slows down.

Fast charging technologies exploit the constant current phase by pumping as much current as possible into the battery before it reaches its peak voltage. Therefore, fast charging technologies are most effective when your battery is less than 50% full but have a diminishing impact on charge time once the battery passes 80%. Fast charging also generates more heat, which can damage the battery in the long run.

There are different types of fast charging standards that are compatible with different phones and chargers. Some of the most common ones are Qualcomm Quick Charge, Samsung Adaptive Fast Charging, OnePlus Dash Charge, etc. These standards use different combinations of voltage and current to deliver different amounts of power to the battery.

For example, Qualcomm Quick Charge 4+ can deliver up to 27W of power in real life (though theoretically, it can do 100W), while Samsung Adaptive Fast Charging can deliver up to 45W of power. You need to use a cable and adapter that support the same standard as your phone to enable fast charging. Otherwise, you may not get the optimal charging speed or even damage your phone or charger.

Fast charging is not just reserved for wired charging. Wireless charging is also getting faster, although it is still slower and less efficient than wired charging. Wireless charging works by using electromagnetic induction to transfer power from a charging pad to a receiver coil inside the phone. However, wireless charging also generates more heat and loses some power during the transmission process. Wireless charging standards include Qi, Samsung Wireless Fast Charge, etc.

Fast charging is a convenient and useful feature that can save you time and hassle. However, you should also be aware of the different types of fast charging standards and how they affect your phone’s battery. You should also avoid using your phone while charging, as this will consume power and slow down the charging process. You should also avoid charging your phone overnight or leaving it plugged in for too long, as this will expose your battery to high voltage and degrade its capacity over time.

How do you turn on fast charging on Android phones?

The answer to your question depends on the type of Android phone you have and the charger you use. Some Android phones support fast charging standards that can boost the charging speed significantly, such as Qualcomm Quick Charge, Samsung Adaptive Fast Charging, OnePlus Dash Charge, etc. You need to use a cable and adapter that support the same standard as your phone to enable fast charging.

If you have a Samsung phone, you may also need to change some settings on your phone to enable fast charging. Here are the steps you can follow:

  • Tap the Settings icon from your home screen.
  • Swipe down the settings options and tap Battery and device care.
  • Tap the Battery option at the top of the list.
  • Swipe down and tap the More battery settings button.
  • Toggle the Fast charging switch on or off under the More battery settings section.

If you have a non-Samsung Android phone, you may not need to change any settings on your phone to enable fast charging. Simply use the charger and cable that came with your phone or a compatible one.

How to charge your Android phone faster

There are several ways to charge your Android phone faster, depending on the type of charger you have and the settings you use. Here are some tips that might help you:

  • Turn off your phone while charging. This will reduce the power consumption of your phone and allow the battery to charge more quickly. You can also turn on Airplane mode to disable wireless connections that might drain your battery.
  • Use a wall outlet instead of a USB port. A wall outlet can provide more current than a USB port, which means your phone will charge faster. Make sure you use the original charger that came with your phone or a compatible one.
  • Don’t use wireless charging. Wireless charging is convenient, but it is also slower and less efficient than wired charging. Wireless charging generates more heat, which can slow down the charging process and damage your battery in the long run.
  • Use a fast-charging cable and adapter. Some Android phones support fast-charging standards that can boost the charging speed significantly. For example, Qualcomm Quick Charge, Samsung Adaptive Fast Charging, OnePlus Dash Charge, etc. You need to use a cable and adapter that support the same standard as your phone to enable fast charging.
  • Turn off or stop using your phone while charging. If you can’t turn off your phone or Airplane mode, you should at least avoid using it while charging. Using your phone will consume power and slow down the charging process. You should also close any apps that run in the background and turn off features like Bluetooth, GPS, Wi-Fi, etc.
  • Charge on the go with portable chargers. If you need to charge your phone while traveling or away from a power source, you can use a portable charger or a power bank. These devices can store power and charge your phone when needed. However, you should choose a portable charger that has a high capacity and a fast-charging output.
