You can use the charger and cable in the box with your Pixel phone to enjoy maximum charging speeds. Using the cable and 18W adapter supplied or any decent third-party one with a similar or higher rating, you can get seven hours of use from a minute charge. Quick Charge achieves fast charging by upping the charging voltage, which in turn boosts the wattage.

Both standards tend to be a bit more conservative in practice. Tapping into the highest speeds of either requires buying a certified charger, but most Samsung devices support either Quick Charge- or PPS-compatible accessories. But in our testing , the Galaxy S8, which has a 3,mAh battery, took about two hours to fully recharge. The fastest, TurboPower 30, delivers 5V and up to 5. Motorola says it works with manufacturers to design custom batteries and that its power management software monitors battery state and health, then adjusts the incoming charge accordingly.

Warp Charge uses a special wall adapter that modulates the amperage in real-time. All this is proprietary. Warp Charge only works with OnePlus phones and compatible wall adapters and car chargers. Every OnePlus smartphone comes with a Warp Charge-compatible wall adapter and charging cord. Warp Charge is designed to dissipate heat quickly.

Warp Charge-compatible devices also have heat management and dissipation hardware that undergo a thorough five-point safety check. As the battery reaches 50 to 60 per cent peak voltage capacity of standard batteries , the electronic controller IC drops down the voltage intakes to prevent battery damage. A fast charger does not follow these rules as much.

It pumps as much as current Amperes as it can, to quickly charge the battery. Many of us may might wonder why high voltages do not damage the battery? A s the fast charging devices have a higher peak voltage capacity batteries and specially designed ICs, so it can pretty high voltages with ease. These devices generally have a peak voltage capacity of 80 per cent which is the reason fast charging is most effective when the battery percentage is below 50 percent.

The entire fast charging process is divided into two phases. The constant phase where the battery voltage steadily increases to reach the highest peak voltage capacity which is then followed by the trickle stage, where the voltage drops down to fully charge the battery. The voltage dropdown keeps battery safe from overheating issues and also extends its lifespan. As fast charging turned mainstream, every smartphone manufacturer started introducing their proprietary standards. The most popular of them is the Qualcomm Quick Charge which powers many devices running Snapdragon processors.

The latest Quick Charge 3. Qualcomm has also announced Quick Charge 4. Like Qualcomm, there are many other brands which use their in-house technologies to boost up the charging capabilities. Try plugging something else into the outlet or plugging your fast charger and device into another outlet. If nothing is working in the outlet, try resetting its circuit breaker. First, make sure your software is up-to-date. If your software is up-to-date, try restarting your device.

As a last resort, you can also choose to factory reset your device. If it is an older device, this might be the case. Try using the fast charger on a different device. If your fast charger works, the problem is with the first device.

Try using the fast charging accessory on a different device. If it still does not work, the problem is likely with the fast charger. If following steps 1 — 7 does not solve the issue, contact the fast charger accessory manufacturer for additional assistance.

Some devices need to have fast charging enabled to work. If fast charging needs to be enabled on your device, you can refer to device manufacturer. For Samsung devices, follow the steps below. To ensure a charger will fast charge your device, you can check with the manufacturer for compatibility.

As a general rule, a charger needs to be at least 18W from a single port to deliver fast charging. Listed Quick Charge devices and speeds reflect capabilities as of July
