We test Huawei's Super Charge 2.0, and the Mate 20 Pro's fast charging proved insane
Huawei's new Super Charge 2.0 that debuts with the Mate 20 Pro, RS and X phones, is a 40W fast-charging system that the company promises will be able to top up the huge batteries of those handsets up to 70% in 30 minutes.

We didn't doubt those claims, as there is already a 50W system on the market - Oppo's Super VOOC - that is able to fully charge the 3400mAh battery of the Find X Lamborghini Edition in 35 minutes flat.

What about the Mate 20 Pro, though, and its large 4200mAh pack? It is arguably the first flagship phone that crosses the 4000mAh mark, and 40W is less than the Super VOOC specs, right? Well, we are happy to confirm that in our first test of Huawei's new and insanely fast Super Charge 2.0 system it has proved its mettle.

The Mate 20 Pro immediately shot to the top of our charging benchmark database, as it was able to top the 4200 mAh unit starting from a dead battery at 9:13 AM, to reach 100% at 10:21 AM, or a bit more than an hour. Looking at the charging log is also pretty telling, as 15 minutes after starting from depleted battery state, it was already at 36%, and 50 minutes after the start it hit 95%, trickling down slower from there. 

For comparison, the 18W Samsung system tops up the Note 9's 4000mAh battery 40 minutes longer than that. For obvious 5W charger reasons, we haven't included any iPhone below, despite that they do have fast-charging circuitry, as you have to buy that brick separately.

Thus, the Mate 20 Pro easily crowns our fast-charging chart, as the 40W charger that comes in its box was able to restore roughly 1.5% of battery capacity per minute of charging on average, compared to 1.1% restoration with the 22W Super Charge 1.0 on the P20 Pro

Long story short, we are moving from the 10-20W fast-charging era to the 40-50W realm, and can only be all the better for it. For those worried about the state of the battery after these insane speeds, Huawei was quick to mention that Super Charge 2.0 has a multi-step safety system built in, and is again certified by Germany's TÜV authority, so we can now sleep tight.

Battery life (hours) Higher is better
Google Pixel 3 XL 7h 39 min (Good)
Samsung Galaxy Note 9 8h 56 min (Excellent)
Charging time (minutes) Lower is better

Not bad. Although I think fast charging kills batteries faster than charging with a 2A charger. Sure, if you only have a short time to charge your phone, utilizing a fast charger can get you through the day until you can charge up at night. But daily use seems to overall shorten long term battery life.

Doesn't seem to be the case in reality though, as this kind of super-fast charging transfers all the heat to the charger itself, and not on the phone, therefore with less heat, means longer longevity.

Im skeptical on PA numbers... I have a Pixel 2 XL and it takes FAR less time than 152 minutes for a full charge.... maybe takes an hour?

Finally some battery advancements. Hopefully all Android flagships will be at least 4000 mAh next year. Apple can remain with their "the same great 18-hour battery life" claim...

That’s the Apple Watch, which easily gets 2+ days. The Max will easily get 2 days as well from a 3100mAh battery.

faster charge time, faster deplete time, shorter battery life. charge the phone with 2A 5v is laster longer than 3A 5v of QuickCharge 3.0

Add iPhone Xs Max to the chart. It have a smaller battery. So surely, it will be the first to fully charge to 100% even with the stock charger.

I promise you it won't. My XS Max charges hella slow with wireless charging. I wish it was faster.
