With wired charging, the phone is powered by the cord (a small load on the battery is there); however, with wireless charging, the phone is powered by the battery and only has to be topped up with the wireless charger. Using a wireless charger instead of a cable means that my battery doesn’t get a break, which means that I’m going through recharge cycles at an even faster rate. So, why is the iPhone Wireless Charger Draining Battery?

iPhone Wireless Charger Draining Battery

Your phone’s battery can’t be drained by a wireless charger because the battery can’t receive and send power simultaneously.

Wireless charger inefficiency is at the root of the issue. The efficiency of connected charging is close to 100%. With 5W of electricity, the mobile receives nearly all 5W when charging via a cable charger. The efficiency of wireless chargers is significantly less than 100%. It’s not unusual for it to reach as high as 72%.

A wireless charger receives and sends 5W of power; however, it will only provide 3.6W of energy to the device. The rest is lost as heat. Because of this, wireless charging is slower than conventional charging for the same amount of power.

Due to the lack of fast wireless charging on the iPhone 8/X, 5W wireless chargers are the only option. The iPhone uses very little power when it is put to sleep. However, if you use your iPhone frequently, it might consume as much as 5 watts of electricity.

Due to its inefficiency, only 3.6W of electricity can be delivered by a wireless charger. For example, wireless charging isn’t likely to meet the iPhone’s 4.5W power requirements. This means that the iPhone will use the wireless charger’s 3.6W output, consuming all of it, leaving no power for the battery to recharge.

However, the wireless charger is unable to fill the 0.9W power gap. So, the battery has to supply 0.9W of power. So, Adrian’s startling battery consumption on his iPhone can be traced back to this fictitious 0.9W load on the battery.

This is not an issue with quick charging capabilities (like some Samsung phones). Since rapid wireless chargers deliver significantly more power (say at 15W) than the device requires, notwithstanding the inefficiency of wireless charging. As a result, when the gadget is in use, there will be no need to use the battery to make up for any deficiency.

Why There Is An iPhone Wireless Charger Drains Battery?

Phones have a good deal of intelligence. Many programs will be shut down as the battery gets low, and finally, the battery will be completely turned down. The charger will fix it. As a result, there’s no reason to be alarmed.

However, the best performance from lithium batteries is achieved between a half and a seventy-eighths charge. With a fully charged 4.1/4.2-volt battery, these should be capable of running down to 3.3/3.4 volts at their lowest point. Chargers put forth an extra effort to trickle charge when the battery voltage drops below 2 volts; chargers put forth extra effort to trickle charge it. However, the phone should not allow this to occur.

1000 hours of battery life depending on how you treat it. If it is misused, it robs its ability to sustain life. Bits and pieces. Battery life will be doubled if it only decreases to half of its capacity before charging. Just a heads up. Treat it with respect but it’s fine to be a little naughty now and then.

Unless it is stored in a drawer for eternity, the cell phone never reaches the bottom. The wireless chargers aren’t as excellent as the old-fashioned wires, but they’re still better than nothing. Nevertheless, if you don’t set it correctly on the wireless pad, or if you have a thick protective layer, it will impact wireless charging’s efficiency.

How iPhone Batteries Are Being Harmed By Wireless Charging?

Battery capacity is maintained at 80 percent through 500 charge cycles, which Apple describes as consuming 100% of a battery’s capacity and refilling it to the same point, but not necessarily all at once. It is possible to complete a full cycle by using 75 percent of the battery on Monday, recharging overnight, and then using 25 percent the following day.

Kingsley-Hughes discovered that his iPhone was going through charge cycles faster than expected thanks to a macOS software called Coconut Battery. His iPhone had been charged 135 times in just over six months of use.

For comparison, I had a look at my iPhone SE. I’ve only used 103 of its battery cycles in the past year. With his current usage/charging habits, Kingsley-Hughes believes that he will reach 500 charging cycles in less than 18 months. I may not even get there before I give mine in for an upgrade.

What’s the reason for this? In the end, it all boils down to the charging process of a smartphone. Apple’s iPhone battery is getting a break when it’s plugged into a wall outlet; it only has to charge and be patient until the cord is unplugged.

While wireless charging doesn’t give the battery a break, it can recharge. If a device receives data, the screen lights up to show notifications, and the battery gets topped off by a charger. Each increment of the battery’s capacity is a percentage point added to the charging cycle and wear and tear on the battery.

Why Does Your iPhone’s Battery Drain So Quickly While Using A Wireless Charger?

As a first step, you need to ensure that the wireless charger you choose is compatible with your phone. Faster wireless charging for iPhones @ 7.5W is available as iOS 11.2 and later. Your iPhone won’t use more power than the wireless charger can offer with such a high-power output rate.

In a power outage, the battery will no longer be required to provide backup power, lowering the overall battery charge cycle usage. On the other hand, not all wireless chargers can supply an iPhone with 7.5W of juice. Other gadgets (such as Samsung cellphones) can receive 15W of power from some chargers, but not iPhones.

A rapid wireless charger must be compatible with iPhones. This is when mophie. The wireless Charging Pad comes in handy. This wireless charger was developed in partnership with Apple to provide 50% faster charging for your iPhone than other wireless chargers.

Does Wireless Charging Destroy The iPhone Battery?

Simply put, the battery in your phone won’t be harmed by wireless charging. Remember not to keep putting your phone on the charging station every time the battery level dips a few percentage points.

Why Is My iPhone Charger Draining The Battery?

Inadequate power being given to the iPhone is one of the leading causes of your iPhone’s battery draining while it is plugged into a charger. This problem should ideally be resolved with a fast-charging adaptor.


On the other hand, wireless charging constantly drains your battery, whereas plugged-in charging gives it a chance to recharge. Even if you don’t own an iPhone, you’re still at risk. Everything that charges wirelessly is subjected to ongoing battery stress, resulting in a shorter lifespan.

Limit your use to top-offs if you want to keep enjoying the newest and greatest mobile technology. Plug your batteries in for a night’s rest. Let me know if you still face iPhone Wireless Charger Draining Battery.

Frequently Asked Questions

My wireless charger is draining my battery, but I’m unsure why?

Critics have pointed out that when phones are charged via a cable, the battery gets a rest, but when they are charged wirelessly, it does not. On the other hand, wireless charging causes the battery to degrade more quickly because it has a limited number of charging cycles.

How long before the battery life is ruined by wireless charging?

Wireless charging stations can harm the battery or the phone itself. Not quite accurate, as it turns out. If you use a cheap wireless charger, you risk damaging your smartphone. Some wireless charging stations are designed to keep the phone safe while being charged.

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 our phone via induction may shorten its battery life.

When it comes to wireless charging, what are the drawbacks?

However, wireless charging has its drawbacks. It’s taking a while: When compared to charging via a cable, wireless charging often takes anywhere from 30 to 80 percent longer to complete a full charge. When placing your device on the mat, keep in mind that it can affect how long it takes to charge.
