Here’s a quick history lesson. When OPPO first announced their VOOC charger, USB-C did not exist in the market yet. It is also the pioneer of super-fast charging for smartphones. Throughout the years, there are many other competitors that released their own version of super-fast charging as well. Then, OPPO came up with their brand new SuperVOOC – the second generation of OPPO’s iconic VOOC.
The OPPO R17 Pro is one of those newer OPPO smartphones that support SuperVOOC. Since we have the OPPO R17 Pro with us, why not test out its speed?
Upon inspecting the SuperVOOC charger that comes with the OPPO R17 Pro, we can see that it is quite compact in size compared to its competitors. We were surprised when we saw the technical details listed on the charger itself.
10V at 5A! That’s a whopping 50W, which is 5 times faster than the now-standardized 5V 2A chargers found in many smartphones. It is also faster than Huawei’s SuperCharge that is found on the Mate 20 Pro, which outputs a maximum of 40W only. The next fastest charger is from the ASUS ROG Phone whereby the HyperCharge can only output a maximum of 30W.
With these information in mind, we already know that the OPPO’s SuperVOOC will be the fastest charger in this test. But just how fast is fast? Let’s conduct an experiment that is similar to what we have done in the past.
Testing the chargers
We use 3 phones for this test. These 3 phones are chosen because they support super-fast charging. The phones are:
- OPPO R17 Pro with OPPO SuperVOOC (50W)
- Huawei Mate 20 Pro with Huawei SuperCharge (40W)
- ASUS ROG Phone with ASUS HyperCharge (30W)
We once again do it like our usual review whereby we will drain the battery and then plug it in and let it charge to 100%. Then we plot the graphs and see just how fast these chargers are.
Let’s take a look at all of the data in a single graph.
Obviously, the OPPO R17 Pro has the fastest charging speed. You might say it has the smallest battery out of all these phones as well. In comparison, that is true.
- OPPO R17 Pro with 3,700mAh battery
- Huawei Mate 20 Pro with 4,200mAh battery
- ASUS ROG PHone with 4,000mAh battery
Let us transform the charging speed to something more comparable. We can estimate by taking the battery capacity and divide it by the total time taken to charge to 100%. That way we can know how many mAh per minute of battery charge.
Since we started charging from 15%, we first have to calculate how much battery capacity to charge to 100%. This is only an estimation that averages the data that we acquired.
|Battery capacity (mAh)||Gap to 100% battery charge (mAh)||Time to 100% battery (minutes)||mAh/minute|
|OPPO R17 Pro||3700||3145||32||98.28125|
|Huawei Mate 20 Pro||4200||3570||54||66.11111|
|ASUS ROG Phone||4000||3400||87||39.08046|
Once again, the OPPO R17 Pro is proven to be the winner once again! We calculated that the OPPO R17 Pro is indeed 1.5 times faster than its next competitor – the Huawei Mate 20 Pro.
What does it mean then?
When OPPO says you can get a day’s use in just 30 minutes of charging, they are not lying. From the graph, we can see that it charged to 50% in just 9 minutes. It took only 17 minutes in total to reach 75%. In just a total of 32 minutes, you get 100% battery charge already!
Imagine just going home one day and the phone is already running low on battery. In half an hour, you get a full charge once more. That is just insanely fast.
Also, let’s not forget that the OPPO R!7 Pro is one of the first smartphone in the world to be using Qualcomm’s Snapdragon 710 chipset. This particular chipset is fabricated with 10nm process – which you can learn why it matters here. With a new chip design, the Snapdragon 710 can provide an even longer battery life by up to 40% thanks to its power efficiency. It can also consume 20% less power for streaming videos compared to its predecessor.
There is also another test from a Chinese YouTube channel that reaffirms our test result here.
