Results Highlights In this Results section we provide short comparative Highlights for each Tablet display based on the comprehensive lab measurements and extensive side-by-side visual comparisons using test photos, test images and test patterns that are presented in later sections.
As we noted in our Google Pixel XL reviewactual charge times on the device were not competitive, ending up in the last place when compared with other solutions, and our extensive testing on the charging times for the purposes of comparison reveals the same.
On the flip side, Dash Charging is proprietary technology, which adds its own set of complications which we will discuss later on in this article. Dash Charge does end up behind Huawei Supercharge when we take into A comparison analysis of the android, and adjust for, battery capacity in the device, as the Huawei Mate 9 has a substantially larger battery than the OnePlus 3.
Huawei Supercharge and Qualcomm Quick Charge 3. We also have temperature data alongside the charging time. This graph coincides with the charge percentage, but had to be separated to keep things simpler, uncluttered and easy to understand.
The situation changes when you look at how these technologies perform when the device is subjected to a real-world workload. The voltage and current regulating circuitry is situated in the Dash Charger, which leads to lower temperatures while charging. The device takes about twice the time to charge if it is being used, and the charging also increases in a peculiarly linear fashion given voltage and current remain constant that is not seen across any of our other tests.
Express mentions like these could not be found on newer support pages, but Samsung continues to recommend devices to be switched off while using Fast Charging.
Other standards continue to occupy positions between these extremes, most lying on the better side of the scale. Even USB Power Delivery, the worst performer of idle-charging takes just about 10 minutes more to achieve the same charge levels under load.
Unlike traditional high-voltage charging solutions, Supercharge employs a relatively low-voltage and high-current formula that aims to maximize the amount of current going into the device, while minimizing efficiency losses, heat, and throttling.
Coupled with the Smart Charge protocol, the Mate 9 also adapts its charging parameters based on the requirements of the battery, as well as the charger supplied for example, it can make full use of a USB-PD charger.
The actual Supercharge charger comes with 5V 2A, 4. Peak current comes close to the 5A rating of the charger, and sustains the 4. However, the Huawei Mate 9 we tested also has a 4,mAh battery, which means the mAh per percentage are higher than on all OnePlus devices, actually putting the standard in a better light and ahead of OnePlus.
There are differences, however, in terms of charging speed, as Super Charge begins leveling off harder than Dash Charge at the 30 minute mark. Under workloads, the rate of charging naturally is lower than during idle charging. As with most marketing statements from OEMs, this is only half true.
Rather than increasing voltage, OnePlus opted for a more even distribution with larger electrical current, meaning more electrical charge delivered per unit of time. This is accomplished via both software and, primarily, through hardware — specifically the charger used, which is non-standard unlike the plethora of QC chargers, for example and thus you need a VOOC or Dash Charger to make use of these charging speeds.
Because the charger converts the high voltage from your wall into the lower voltage the battery requires, most of the heat from this conversion never leaves the charger — in turn, your phone remains cooler. The consistent current going into the phone coupled with the lower temperatures on the actual handset allow for reduced thermal throttling, which impacts both charging speed and consistency as well as the direct user experience.
This is not only extremely fast, but there are also a few perks that come with it. The charging speed is fastest and one of the fastest at those lower percentages, ensuring you can get extreme amounts of charge in just a few minutes should you be running low on battery.
Moreover, the thermal consistency and lack of throttling is no joke. As we can see from the data supplied, the difference between under-load charging and regular charging is minimal.
And this does mean that you will not notice slowdowns, additional stutter or general throttling side effects whilst using your device. And you need both the charger and the cable to make Dash Charge work its magic.
If you can look past those inconveniences and incompatibilities, Dash Charge is a clear winner in both speed and consistency. The heat reduction could even lead to increased battery longevity. Qualcomm Quick Charge 3. While we are focusing on Quick Charge 3.
But again, we should re-emphasize that Quick Charge 3. This coupled with a higher voltage than competitors does allow the standard to expedite charging time, while preventing overheating and ensuring battery safety. By determining which power level to request at any point in time, QuickCharge also prevents damaging the chemical composition of the battery while still providing an optimum charging speed taking into account factors like temperature and available power output.
Still, looking at the graphs provided, one can see the finer granularity and wider range of voltage steps are clearly being taken advantage of. This holds extreme significance given Qualcomm is essentially granting the option to provide faster charging to dozens of smaller OEMs, or of bringing faster charging to mid-range devices through mid-range chipsets.
This, in turn, improves the minimum baseline of fast charging offerings, in turn promoting competition and prompting those brands that do offer fast charging as a specific selling point to aggressively improve or market their solution.
USB Power Delivery USB as a standard has been evolving for years, from a simple data interface that eventually became widely-used as a constrained power supplier, to a fully-fledged primary power provider alongside a data interface. Many small devices have featured USB charging for years, and you probably have a handful of peripherals being powered up by USB cables right at this moment.
Power management in the initial generations of USB, however, was not meant for battery charging — rather, it was cleverly exploited for that by manufacturers who saw the slow power delivery was enough for the small batteries of their products.
Of course, smartphones have no need and cannot take in! In most charging circumstances, however, voltage goes up to 5V with current sitting just under 2A, with the highest power draw we found during charging being just under Aug 17, · Fortnite on Android.
