For as long as cellphones have known, wireless charging has been an issue. Initially, there were several obvious drawbacks, but as the technology progressed, issues like the requirement for exact placement or the incredibly slow charging speeds were eliminated. Let us read Does Wireless Charging Drain Faster?

Mobile devices like Samsung’s Galaxy phones and Apple’s iPhones have boosted interest in wireless charging to unprecedented levels. With the widespread acceptance of the Qi standard, the Wireless Power Consortium appears to have won a potentially problematic standards struggle.

Wireless charging has been a favorite of ours for some time now. Even if it’s dark and you don’t want to wake your partner, it’s nice to be able to charge your cell phone without having to deal with a cord.

Because of this, some have begun to wonder if wireless charging comes at a price. Several articles, forums, and comments have suggested that wireless charging may deteriorate your battery more quickly than standard wired charging. We decided to investigate to see if this notion is true.

Does Wireless Charging Drain Faster?

Since the battery cannot receive and output power simultaneously, a wireless charger cannot drain your phone’s battery. However, poor wireless chargers, faulty phone hardware, or power-hungry applications may cause your phone’s battery to discharge faster than it can be wirelessly charged.

Wireless Charging Drain Faster

You’re asking that question as if you felt the battery’s life was going to be ruined in a couple of days, and you’re right. That’s not true. While it does worsen the battery’s performance, it isn’t fatal.

What I mean is this: Due to the greater losses that occur while using a cable. Heat is now generated as a result of greater energy being wasted. Batteries degrade faster when they are exposed to more heat.

As a result of the low heat created, battery degradation is virtually unaffected. You may see some battery degradation if you use rapid wireless charging or fast charging (and I mean the genuine fast ones, not Apple’s new ones). But you’re sacrificing battery life for the convenience of fast charging your phone.

You can think of it as starting your car in the winter and leaving it running for a few minutes to warm up the interior. No, that’s not good for the engine, and it will degrade more quickly, but the ease with which you can jump into a warmed-up car might make it worthwhile.

Why Does Fast Wireless Charging Deplete Phone Battery Life More Quickly?

When it comes to wireless charging, there have always been drawbacks and advantages. Your phone’s battery life is jeopardized because of fast or regular wireless charging. Despite this, advantages such as ease of use, broad interoperability, and the absence of cables are still present.

As a result, we’ll examine how rapid wireless charging affects the battery life of Apple’s newest phone using it as a test case. Charge cycles (from 0% to 100%) are used more quickly while using fast wireless charging.

Charge cycles are the total number of cumulative charges and discharges that account for 100% of the battery’s capacity. There is a limit to how many charge cycles a battery can take before losing capacity. The smartphone is powered (at least for its most important functions) while charging takes place through a micro-USB or USB-C cable, allowing the battery to rest while being recharged.

On the other hand, wireless charging only recharges the battery while the phone is still running. As a result of the repeated charging and discharging, the battery’s remaining charge cycles are reduced. Because the heat generated by fast wireless charging is detrimental to the battery’s lifespan.

The charger’s induction coils must create an electromagnetic field for wireless charging to work. Your smartphone’s battery gets recharged when a magnetic field reaches the receiving coil at the back of the device. Wireless charging emits a lot more heat than conventional charging, especially if you’re using a lot of power, such as in the case of fast wireless charging.

Is There A Downside To Wireless Charging?

Compared to a cable, wireless charging often requires 30-80% more time to charge your device entirely. Remember that the charging time for your smartphone can vary depending on how you position it on the mat.

Can A Wireless Charger Drain Your Phone Battery?

Since a phone’s battery can’t accept and send power simultaneously, a wireless charger won’t drain the battery while charging. However, your phone’s battery may drain quicker than it can charge wirelessly if you use a low-quality wireless charger, if your phone’s hardware is broken, or if you use apps that require a lot.


Is there a drawback to wireless charging? Or Does Wireless Charging Drain Faster? That is true; however, your battery has already reached half-life, and its capacity is diminishing with time.

However, the convenience and speed of wireless charging are enough to persuade many to join the movement. With these techniques and a wireless charger designed to provide the best wireless charging experience, you should be able to extend the life of your battery.

Frequently Asked Questions

Is it more or less efficient to use wireless charging?

Using a traditional cable to charge a Pixel 4 from 0% to 100% used 14.26 Wh (watt-hours), whereas using a wireless charger to do the same used 21.01 Wh, a 47% increase in energy consumption.

If you use a wireless charger, may it use up all your phone’s power?

According to a new scientific study, wireless charging could cause iPhone and Android phones to lose battery life. University of Warwick researchers have shown that charging your phone via induction may shorten its battery life.

Is it safe to charge my iPhone wirelessly overnight?

Using a wireless charger is completely safe, so you can leave your phone on your nightstand or desk all day while you’re at work.

How safe are wireless chargers compared to wired ones?

Wireless charging is safer because it stops charging as soon as you remove it from the device. In addition, “plugging into public USB chargers” carries a less well-understood risk. You may not be aware of the data collection on these free USB public charging hubs, which is yet another cause why wireless charging is preferred over wired options.
