The fastest way to charge the Samsung Galaxy Note 9

By [email protected] Topic: Tech Specs

If you’ve recently bought a Samsung Galaxy Note 9, you probably fit a profile: You are a demanding power user that evaluates just about every feature of a phone before you buy. You want long battery life, and lots of features.

If you want all that in a phone, then you probably want to know how to charge it fast as well. And with a whopping 4,000 mAh battery, having a high-powered charger is key.

As we do with every flagship phone, we got our hands on the Samsung Galaxy Note 9 and ran tests to help you pick the fastest charger.

For the tests, we start each phone at 5 percent charge and track the battery power level of the phone every 15 minutes for the first hour of charging. There’s an important reason why we do it this way. A phone is capable of charging at its fastest rate before it reaches about 75 percent capacity, then limits the amount of power it accepts as it approaches 100 percent battery. Therefore, the real advantage of a fast charger is best noticed in the first hour of charging.

And when you think about it, it just makes sense. If you need power fast, it’s probably because you are in the red zone.


The charger that Samsung provides with the Note 9 is compatible with Qualcomm® Quick Charge™ 2.0. In one hour, it took the smartphone from five to a little more than 70 percent. The wallport rq1300, a Qualcomm Quick Charge 3.0 charger, had results that were about 5 percent better in the first 15 minutes, and extended its lead over time. That’s not surprising. When Qualcomm released Quick Charge 3.0, it said the update to its fast charging technology offered better heat management and efficiency during charging, while the speed gains were not as significant.

Wireless charging

When you look to wireless charging, you’ll trade speed for convenience, and we’re seeing that with the Note 9. All of Ventev’s wireless accessories meet or exceed the charging power of any phone on the market, so they’ll charge any wireless charging enabled phone at its fastest possible wireless speed.

If time is on your side, consider adding a wireless charger to your home or office for topping up without plugging in. The wireless chargepad+ fits seamlessly into any décor with its low-profile design and gray cloth covering. The wireless chargestand – available in white or gray – offers additional versatility with two viewing angles when you’re device is propped up.

The verdict

If you are looking to upgrade your charger for the Galaxy Note 9, keep an eye out for Qualcomm Quick Charge-compatible chargers, like the wallport rq1300. On the wireless charging front, the wireless chargepad+ and wireless chargestand get points for convenience and style.
