This question commonly arises due to the heat associated with bombarding your device with high amounts of power. And as you may already know, heat is bad for your battery—especially lithium-ion battery, which is what most smartphones use today. That's why fast charging systems strive to reduce the heat as much as possible while increasing the output.
Not really, no. This is due to how fast charging works. Fast charging batteries have two phases of charging. The first phase is where they take in as much power as possible. The first phase is usually when the battery capacity is low or empty. It's also worth keeping in mind that your phone may automatically turn off fast charging if your device's temperature exceeds a certain level.
Smartphone companies have also devised other ways to reduce the impact of the fast charging phase on the battery by using a dual-battery design. This way, the two batteries share the high input load during the fast-charging phase—thus preventing damage.
Another preventive measure is the different battery management software systems. Using available charging infrastructure, StoreDot is aiming to deliver miles of charge to a car battery in five minutes in But if the experience of the driver is exactly like fuelling [a petrol car], this whole anxiety goes away.
Existing Li-ion batteries use graphite as one electrode, into which the lithium ions are pushed to store charge. But when these are rapidly charged, the ions get congested and can turn into metal and short circuit the battery. The StoreDot battery replaces graphite with semiconductor nanoparticles into which ions can pass more quickly and easily.
These nanoparticles are currently based on germanium, which is water soluble and easier to handle in manufacturing. Myersdorf said the cost would be the same as existing Li-ion batteries.

It can deliver up to 24W of power. Meizu has also demoed their future Super mCharge solution which can deliver up to 55W of power but it's yet to release a smartphone integrating it as of the time of writing this.
Wireless or inductive charging uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. Induction is achieved by placing a device which is equipped with the induction coil directly onto a dedicated charging station or charging pad.
While there used to be at least a few competing wireless charging standards in the past, nowadays the entire mobile industry has moved to using Qi pronounced "chee". Much like with the regular wired charging - wireless charging can be performed at different rates. The nominal power output of a Qi charging pad is 5W but faster chargers can already pump out up to 15W of power to phones which support it.
