iPhone 12 Pro: Fast smartphone with brisk Qi charging
Wireless charging smartphones have been standard at Apple since the iPhone 8 and iPhone X. The 12th generation iPhones can be wirelessly supplied with energy even faster than their predecessors, for example the iPhone 12 Pro: How many watts and how fast you inductively charge it depends on which Qi charger you use. A maximum of 7.5 watts is possible with the standard charger.
You can do twice as much with the Magsafe charger from Apple: The small puck supplies the iPhone 12 with 15 watts , so an empty battery is half full after an hour. Magsafe has another advantage: the smartphone automatically docks via the integrated magnets. With older iPhones you only get 7.5 watts and no magnetic connection. The iPhones do not master reverse charging, i.e. the supply of other devices with energy via the smartphone.
The battery of the iPhone 12 has a capacity of only 815 mAh, but thanks to the interaction of the components it is durable. It lasts up to 17 hours when you watch videos, and up to eleven hours when you stream.
The powerful A14 processor in the iPhone 12 Pro processes commands quickly. The other features are also excellent: The 6.1-inch (approx. 15 cm) large and bright OLED screen displays content sharply. The three cameras on the back offer a wide-angle, ultra-wide-angle and a telephoto lens – and an improved autofocus as well an optical zoom.

Xiaomi Mi 11: high speed Qi charging and extras
A disadvantage of smartphones with wireless charging is that charging by cable is usually much faster. It is different with the Xiaomi Mi 11: The top smartphone can be charged with 50 watts if you put it on a Qi charger. This means that the battery is full in an hour. For comparison: the power supply unit delivers 55 watts via cable, which is only slightly more.
The cell phone offers another extra feature – reverse charging: it supplies other devices with power , such as headphones, with up to 10 watts. You just have to support the Qi standard as well. The large battery with 4,600 mAh of the Mi 11 also lasts a long time in everyday life.
The smartphone is also excellently equipped in other ways. The Snapdragon 888 chip makes it work fast. The 6.81 inch (17.3 cm) AMOLED display with 120 Hz ensures sharp images and smooth scrolling. Last but not least, a triple camera with wide angle, ultra wide angle and macro lens is part of the equipment.

When scrolling, the refresh rate of 120 Hz ensures that you don't get stuck. The triple camera comes up with wide-angle, telephoto and ultra-wide-angle sensors as well as an optical image stabilizer.

With extras such as tilt-shift, night mode or time lapse, even more unusual recordings are possible.
The OnePlus phone works at lightning speed thanks to the Qualcomm Snapdragon 888 processor. With protection class IP68, it is safe from dust and water. The 6.7-inch (approx. 17 cm) AMOLED display shows videos, games and other content razor-sharp and without jerking.
