Warp Charge VS other fast loading patterns – the 30 minute load test


The OnePlus 6T McLaren edition debuted a new charging standard for OnePlus to succeed with its 20W Dash charger. So with the Chinese phone manufacturers bringing in more patterns of charging owners, we want to show how they compare to other standards in the market.

There are several fast charging standards across the smartphone industry that have their own advantages and disadvantages. In short, fast charging is great and convenient for the customer, but proprietary charging patterns mean you can only get these speeds with the original cable and adapter.

We have compiled some graphs with various patterns of rapid collection and put them against each other. Note that for this comparison, we are only comparing the speed with which the device charges in the first half hour a discharged battery. This is most crucial in judging how much resistance you can expect from a device if you only have 30 minutes to load it between flights or before you need to leave the door.

The raw data we're using is the percentage of a 30-minute charge for a discharged battery, the battery capacity, and just for fun. We will also incorporate our battery resistance scores for this comparison.

The first graph is the gross charge percentage after charging for 30 minutes. Of course, the percentage depends on the total capacity of the battery and how fast the power can be restored to the battery.

Right away, the Super VOOC charge from Oppo Find X is unbeaten. It charged for an impressive 95% of the battery in just half an hour. Meanwhile, the Google Pixel 2XL with its 18W USB-PD charger reached only 35%, with the Samsung Galaxy Note9 not too advanced, with 37% using the Adaptive Fast Charger.

This chart estimates how much battery capacity is restored based on the percentage and capacity of the phone. The Find X is now very close to the Huawei Mate 20 Pro, as Huawei has the largest (4,200 mAh) battery in the group. Meanwhile, Note9 and Pixel 2 XL are still the latest.

Finally, the last chart takes into account the battery resistance score we assign to these phones when we analyze them. Simply put, this is our battery resistance rating of how much battery the phone can charge in half an hour.

Mate 20 and Find X were close to each other on the capacity chart, but the resistance graph reflects the difference in battery resistance between the two devices – still very impressive numbers from Huawei.

The OnePlus 6T with Dash Charge and the live Nex S with Quick Charge 3.0 were neck and neck at 30-minute load tests, where they scored 55% and 50%, respectively. This resulted in a capacity load of about 2000 mAh in each device, with roughly the same resistance estimates at 50h.

Chinese brands are far ahead of other industry standards, such as USB-C Power Delivery and Qualcomm Quick Charge on smartphones, simply because the competition between Chinese brands is so fierce. We have to wonder when there will be a fast loading pattern across the industry that will exceed the 20W-25W range.

USB-C Power Delivery has perhaps the highest potential to be an industry-wide standard (it loads many laptops, after all) and it's already fairly easy to find USB-C PD power banks, and Apple uses the same standard in their laptops.

Until then, will we see other phone manufacturers developing their charging patterns outside of China?
