If you’re considering to switch from plug-in to wireless charging, you’ve probably done a lot of research and have heard or read about its effects on mobile phones.
Confused as to what claims about wireless charging are true and what aren’t? To dispel some false beliefs about wireless charging, we’re listing them here and sharing the real score about each misconception.
Myth #1: Wireless charging pads can damage the phone or its battery.
Fact: Not entirely true. Chances of your smartphone getting damaged are high if you use a low-quality wireless charger.
Some wireless charging pads are built to prevent damage to the phone while in use. The Futura X, for example, features a magnetic alignment that guides the phone to the proper charging spot, so the user won’t risk fumbling and dropping the phone.
Myth #2: Off-brand chargers are defective.
Fact: Not all unofficial third-party wireless charging devices are faulty products.
A distinction should be made between an off-brand charger and a fake or knock-off charger. Some wireless chargers perform well even if they’re off-brands because they’re manufactured using strict quality standards and are supplied by reputable retailers. As long as you’re using a certified premium-quality wireless charger like the Prelude, nothing bad will happen to your mobile phone.
In contrast, you’re going to take a big risk with cheap and fake wireless chargers. They’re likely produced without quality control measures and are supplied by shady distributors.
Myth #3: Wireless chargers don’t work with older phones.
Fact: By themselves, older phones that are Qi-enabled can’t be charged directly with wireless charging devices because they don’t have a built-in receiver. But they can still be charged wirelessly by attaching a third-party add-on like a receiver patch at the back of the phone.
Myth #4: Leaving your phone turned on while it’s charging will damage it.
Fact: You shouldn’t be bothered if you’re charging your phone and keeping it on just to receive messages or play music (with the screen turned off).
What you must watch out for are conditions that cause overheating and eventual phone damage such as running graphics-intensive apps and poor ventilation while powering up your phone on a wireless charging pad.
Myth #5: Charging your phone overnight will damage it.
Fact: Smartphones and even wireless charging devices are smart enough to stop transmitting power to your device the moment your phone is already fully charged.
Charging your phone for a longer period might be harmful though, as wireless charging pads still produce some heat. So be careful not to leave your phone on the wireless charger for unreasonably extended periods. To maximize your phone’s battery life, keep your phone charged between 40% and 80%.
Wireless chargers are generally safe and convenient to use with proper handling and use of both your phone and the charging device. It also boils down to the quality of wireless charging device you’re going to use, so pick one wisely.
FAQs
The most common reason wireless charging is inhibited is improper placement on the charging pad. The wireless connection between the device and the charging pad may be interrupted, cutting off the power supply.
What are the cons of wireless charging? ›
Cons of wireless charging
It may seem like a no-brainer to go wireless. But there are some disadvantages of wireless charging. It's slow: Wireless charging typically takes 30-80% longer to fully charge your device than a cable. Keep in mind: how you place your device on the mat can affect how long it takes to charge.
What is the bad side of wireless charging? ›
Wireless charging generates heat, which can affect the longevity of your phone's battery. Excessive heat can accelerate battery degradation, reducing its overall lifespan.
What is the biggest challenge of wireless charging? ›
Compared to established conductive EV chargers, the main issues are high initial cost and limited power transfer efficiency.
How bad is wireless charging for battery life? ›
Charging a battery from 50% to 100% will therefore only use up half of a battery cycle. Because battery charge cycles are influenced by the number of times they are charged rather than the charging method, wireless charging will not harm a device's battery.
How inefficient is wireless charging? ›
The efficiency rate of inductive chargers usually falls between 70% and 80%, though some newer models boast efficiencies closer to 90% under optimal conditions. This is slightly lower than the 90% to 95% efficiency rate often seen in traditional wired charging.
Does wireless charging cause overheating? ›
During wireless charging or fast charging, the device may feel hotter to the touch. This does not affect the device's lifespan or performance and is in the device's normal range of operation. If the battery becomes too hot, the charger may stop charging.
Is wireless charging worse than wired? ›
Speed: Wired charging, especially with fast-charging technologies, is typically much quicker than wireless charging, making it ideal for quick power-ups. Efficiency: It offers more energy-efficient charging, with less power lost during the charging process compared to wireless methods.
Is wireless charging safe overnight? ›
Just as with a cable, it's safe to wirelessly charge your phone overnight and charging will stop once your battery is full.
How does wireless charging impact the environment? ›
Decreased Physical Waste: Traditional charging methods involve cables and connectors that can wear out and need to be replaced. Wireless charging minimizes this issue as there are no physical connections that deteriorate over time, thereby reducing the waste generated from the disposal of these components.
The materials used in charging pads and cases can affect wireless charging speeds. Certain materials, such as metal, can interfere with the electromagnetic field, reducing charging efficiency.
Does wireless charging slower? ›
Wireless charging is generally slower than traditional wired charging. Let's take the iPhone 11 Pro as an example. A Power Delivery wall charger can provide up to 18W, while the wireless charger can only provide a maximum of 7.5W.
Is it okay to leave phone on wireless charger overnight? ›
Most charging pads will safely trickle charge your phone battery to keep it fully charged at all times, so it's perfectly safe to leave it on the charging pad or mat overnight or for an extended period of time.
Why wireless charging is not popular? ›
Wireless Charging Is Bad for the Environment. Wireless chargers need almost 50% more energy to charge your phone than wired chargers, wasting more energy. Also, since wireless charging heats your smartphone, it damages its overall battery health—forcing you to upgrade to a new phone more often.
Is wireless or wired charging better? ›
Wireless charging stands out for its convenience and the futuristic feel of cable-free charging, making it a perfect fit for those who value aesthetics and ease of use. On the other hand, wired charging continues to appeal to those seeking faster charging speeds and a more energy-efficient solution.
Why is my phone dying on a wireless charger? ›
Overheating can contribute to battery drain while charging. To address overheating issues, ensure that your phone is not exposed to direct sunlight or placed on surfaces that retain heat, such as blankets or pillows. You can also close unnecessary apps running in the background, as they can cause your phone to heat up.
