Some time ago, when the world only saw reverse charging, I thought it had no chance and only worked on the smartphone in which it was installed. Advertisements show you can charge your smartphone using other smartphones. I tried to do this, but charging was very slow. Also when charging both smartphones became very hot and the “donor” was very quickly discharged. The other day I came across a situation that made me change my mind about this feature. It made me not only think about it but also want a smartphone with reverse charging, which is now almost non-existent.
What is reverse charging?
Not so long ago, smartphones used to have this function but many users still think it’s unnecessary. I’m talking about wireless charging. I used to only use it occasionally but now I almost always keep my smartphone on the charging station and forget about what a discharged battery is. You don’t have to do anything special, but there is an effect. Charging speed is lower but it’s used more for ongoing charging and not for fast charging.
Reversible wireless charging is based on conventional wireless charging. The coil inside the smartphone can both “take” the charge and create it. Given this is a smartphone and not an electrical outlet, the charging speed predictably becomes very low due to low power. That is what initially pushed me when I thought about this function.
When I changed my mind about reverse wireless charging
Now I use two phones, one of which is the iPhone 11 Pro. I use it to listen to music and podcasts. I have AirPods Pro headphones with a wireless charging case, so I found myself in a situation where my headphones ran out of battery.
From the outlet, the headphones charge in less than an hour, but I didn’t have any available sockets. At the same time, I was sitting at the table and could calmly lay out my smartphone and headphones.
In this situation, I realized there is still reverse charging. This function doesn’t take up space inside the case and doesn’t affect weight or spoil the appearance. But in an emergency, it can help charge something small.
Occasionally it can even be used to charge another smartphone, but my experience has shown this is still an undertaking. I charged the iPhone X from the Huawei P30 Pro and after 30 minutes of charging only a couple of percent of the battery was added. The situation was complicated by the fact I was driving in a car and couldn’t place the smartphones on top of each other.
Later, I conducted an experiment and realized that the charging speed had not changed much but they kicked out less heat. The smartphones were also without covers so nothing would affect charging speed.
Can I use wireless charging?
Many people don’t use wireless charging because they worry about their smartphone’s battery. Their fears are justified, because the temperature is higher.
It’s worthwhile to know you can ruin your smartphone with a bad cable, a non-original power supply or an external battery. Sometimes even a good powerbank can burn off the power controller in a smartphone or just damage the battery. When transmitting via cable many things can cause increased risks from a power surge on the power supply to a circuit if moisture enters the connector. In this case, wireless charging is essentially the safest way even if it does take longer.
When is wireless charging convenient?
Even if we constantly use a smartphone, nothing prevents us from placing it on a charging platform rather than a surface. I always knew that I use it a lot, but underestimated how long it was on the table until I started using wireless charging.
As a result, I put one at home and one at work and always hit the road with a 90-100 percent charge. I didn’t charge through a cable for weeks.
I find it particularly convenient to charge them vertically. Modern smartphones have a face unlock feature. When a message arrives, the screen turns on, you look at it and the message is displayed on the screen. You can configure the unlock function to show the home screen. In this case, the smartphone turns on and you can immediately answer. You don’t need to use your hands to pick up your smartphone to view notifications.
All this makes wireless charging a really convenient way to recharge your phone’s battery.
