Qi is an established, universal technology standard available to developers ans consumers right now. The widespread industry adoption means Qi is available in many locations where wireless charging is most needed, including airports, hotels and offices.
When you have Qi wireless chargers by your bed, in your car, at work or on the go, you can have confidence and never have to worry about a dead battery. Most users of wireless charging find that they do “power grazing”, that is instead of just putting their phone down on a desk, table, or car console when not in use they put it on their Qi wireless charger. If they need to use their phone they just pick it up. No wires to fumble with and their phone keeps a healthy charge all day without even thinking about charging.
