Quick Charge is a fast-charging standard that lets your phone charge much faster than the standard charger that came with it

Quick Charge is a technology made by Qualcomm that speeds up how fast your phone's battery fills. Instead of taking two or three hours to charge from empty, a Quick Charge-compatible phone can reach 50 or 80 percent in 30 to 45 minutes. It does this by sending more electrical power to your phone's battery than a regular charger does — but in a way that is designed not to damage the battery.

Quick Charge is built into the charging chip inside your phone. If your phone has it, you need a Quick Charge charger and cable to use it. A regular charger will still work with a Quick Charge phone, but it will charge at normal speed. Quick Charge is most common on Android phones made by Samsung, OnePlus, Motorola, and others. iPhones do not use Quick Charge — Apple uses its own fast-charging system.

Key Takeaways

  • Quick Charge is a Qualcomm technology that charges compatible Android phones much faster than standard chargers, typically reaching 50 percent battery in 30 to 45 minutes.
  • Your phone must have Quick Charge built in to use it, and you need both a Quick Charge charger and a Quick Charge cable — a regular charger will not activate the fast-charging feature.
  • Quick Charge comes in different versions (3.0, 3.1, 4.0, 5.0), and newer versions charge faster, but your phone will only charge as fast as its oldest component allows.
  • Fast charging generates heat, so phones with Quick Charge often have built-in safety features that slow charging if the battery gets too warm.

How Quick Charge actually works

A standard phone charger sends power at a fixed voltage and current — usually 5 volts and 2 amps. Quick Charge chargers send higher voltage (up to 20 volts in newer versions) and adjust the power delivery based on what the phone's battery needs at that moment. The phone's charging chip talks to the charger and says "send more power" when the battery is cool and empty, and "slow down" as the battery fills and gets warmer.

This back-and-forth communication is what makes Quick Charge safer than just cranking up the power to maximum. A regular charger cannot do this — it just sends the same amount of power the whole time. That is why you cannot get Quick Charge speeds by using a high-powered charger that is not Quick Charge certified.

Quick Charge versions and what they mean

Qualcomm has released several versions of Quick Charge over the years. Quick Charge 3.0 and 3.1 were common on phones from around 2015 to 2019. Quick Charge 4.0 and 4.0+ appeared around 2017 and 2018. Quick Charge 5.0 came out in 2020 and is now standard on many newer flagship phones. Each version is faster than the last.

The version that matters is the slowest one in your setup. If you have a Quick Charge 5.0 phone but only a Quick Charge 3.0 charger, your phone will charge at Quick Charge 3.0 speeds. If you have a Quick Charge 4.0 charger but a Quick Charge 3.0 phone, same thing — the phone charges at 3.0 speeds. They are backward compatible, meaning newer chargers work with older phones, but you do not get the speed benefit of the newer version.

Which phones have Quick Charge

Quick Charge is built into most mid-range and flagship Android phones. Samsung Galaxy S and Note lines have had it for years. OnePlus phones use Quick Charge on most models. Motorola, Google Pixel (on some models), and many others include it. The only way to know for sure is to check your phone's specs on the manufacturer's website or in the original box — it will say "Quick Charge 4.0" or "Quick Charge 5.0" if your phone has it.

iPhones do not use Quick Charge at all. Apple uses a proprietary system called USB Power Delivery, which is a different standard. Some Android phones also support USB Power Delivery alongside Quick Charge, which gives you more charger options.

Heat and battery safety with fast charging

Charging faster generates more heat inside the battery. Lithium batteries do not like heat — it can shorten their lifespan over time. Most phones with Quick Charge have thermal management built in: if the battery gets too warm, the phone automatically slows down the charging speed to protect the battery. You might notice your phone charges slower if it is hot, or if you are using it while charging.

This is normal and intentional. It is not a sign that something is wrong with your charger or phone. If you want to charge as fast as possible, charge in a cool room and do not use the phone while it is charging. The phone will speed back up once the battery cools down.

Choosing a Quick Charge charger and cable

If your phone supports Quick Charge, you need both a Quick Charge charger and a Quick Charge cable to get fast speeds. A regular USB-C cable will not work — it does not have the right pins to communicate with the charger. You do not need to buy the exact charger the phone came with, but you do need one certified for Quick Charge.

Chargers from Qualcomm, Samsung, OnePlus, Anker, Belkin, and other established brands are generally safe. Avoid very cheap third-party chargers with no brand name, because they may not have the safety features that prevent overcharging or overheating. A certified Quick Charge charger costs between $15 and $40 depending on the wattage. The cable usually costs $10 to $20.

Quick Charge versus other fast-charging standards

Quick Charge is not the only fast-charging technology. Samsung phones also support Samsung Adaptive Fast Charging. OnePlus phones use Warp Charge or Dash Charge depending on the model. Motorola has TurboPower. These are all proprietary systems made by each company, and they work similarly to Quick Charge — they send higher power and adjust based on battery temperature.

USB Power Delivery is an open standard that many phones support, including some Android phones and all modern iPhones. It is slower than Quick Charge in many cases, but it means you can use the same charger across different devices. Some newer phones support both Quick Charge and USB Power Delivery, giving you flexibility in which charger you use.

Frequently Asked Questions

Will using Quick Charge ruin my battery?

No. Quick Charge is designed to be safe for daily use. The phone's built-in thermal management slows charging if the battery gets too warm. Over many years, all lithium batteries degrade slightly, but Quick Charge does not speed up that process significantly compared to regular charging.

Can I use a Quick Charge charger on a phone that does not have Quick Charge?

Yes, it will work, but the phone will charge at normal speed. The charger will not damage the phone — it will just send regular power because the phone's charging chip does not request the higher voltage. You are not wasting the charger, but you are not getting the speed benefit either.

Do I have to use the original charger that came with my phone?

No. Any certified Quick Charge charger will work with your Quick Charge phone. You do not need the exact brand. Just make sure it is certified for Quick Charge and matches your phone's Quick Charge version or newer.

Why does my phone charge slower when it is hot?

Your phone is protecting the battery. When the battery gets warm, the charging chip automatically reduces power to prevent damage. This is normal. Once the phone cools down, charging speed will return to normal.

Is Quick Charge the same as wireless charging?

No. Quick Charge is wired charging — you plug a cable into your phone. Wireless charging uses a pad or stand and is much slower. Some phones support both, but they are separate technologies.
