Does iPhone 7 Have a Wireless Charger? The Definitive Answer & Complete FAQ Guide

The straightforward answer is a resounding no, the iPhone 7 does not have wireless charging capability built-in. It’s a feature that arrived later in the iPhone lineup. However, before you resign yourself to being tethered to a cable, let’s dive deeper and explore the alternatives and the reasons behind this design choice. We’ll also answer your burning questions about wireless charging in the context of older iPhones.

Why No Wireless Charging on the iPhone 7?

The absence of wireless charging in the iPhone 7 boils down to technological limitations and Apple’s strategic roadmap at the time of its release in 2016. While wireless charging technology (specifically Qi) was gaining traction, it wasn’t yet mature enough to meet Apple’s stringent performance and efficiency standards.

Material Matters: The iPhone 7 features an aluminum unibody design. While aesthetically pleasing and structurally sound, aluminum inherently blocks electromagnetic fields, which are essential for wireless power transfer. To implement wireless charging, Apple would have needed to switch to a glass back, which they eventually did with the iPhone 8.
Efficiency Concerns: Early wireless charging technologies were significantly less efficient than wired charging. Apple prioritizes battery life and optimized performance. At the time, the efficiency trade-off associated with wireless charging likely didn’t align with their goals for the iPhone 7.
Strategic Release: Apple often introduces new features incrementally across its product lines. By holding back wireless charging for later models, they could create a compelling upgrade path and differentiate newer iPhones from older ones.

Can You Add Wireless Charging to an iPhone 7?

While the iPhone 7 doesn’t have built-in wireless charging, you can effectively add this functionality using third-party accessories. Keep in mind that these solutions are not officially supported by Apple and may come with caveats.

Wireless Charging Cases: These cases essentially wrap your iPhone 7 in a compatible receiver, allowing it to charge on a Qi-enabled wireless charging pad. The case typically connects to the Lightning port.
Wireless Charging Adapters: These adapters are thin, flexible circuits that plug into the Lightning port and attach to the back of your iPhone 7. You can then place your phone on a wireless charging pad. These are usually less bulky than cases, but can feel less integrated.

Important Considerations When Using Third-Party Solutions

Charging Speed: Third-party wireless charging adapters and cases may not offer the same charging speed as wired charging or even as the wireless charging speeds found in newer iPhones.
Compatibility: Ensure the accessory you choose is compatible with your iPhone 7 and supports a reputable wireless charging standard like Qi.
Aesthetics: Adding a case or adapter will inevitably alter the appearance of your iPhone 7. Consider the design and how well it complements your phone.
Potential Risks: Low-quality accessories could potentially damage your iPhone 7’s Lightning port or impact battery performance. Choose reputable brands and read reviews carefully.

Frequently Asked Questions (FAQs) About iPhone 7 and Wireless Charging

Here are 12 commonly asked questions about the iPhone 7 and its relationship (or lack thereof) with wireless charging:

1. What is Wireless Charging and How Does it Work?

Wireless charging, also known as inductive charging, uses electromagnetic fields to transfer energy between two objects. A charging station sends power wirelessly, which is then received by a compatible device. The most common standard is Qi (pronounced “chee”), which allows devices to be charged without needing to be plugged in. You simply place your device on a Qi-compatible charging pad.

2. Is the iPhone 7 Compatible with Qi Chargers?

The iPhone 7, without any additional accessory or add-on, is NOT compatible with Qi chargers. As explained earlier, it lacks the necessary hardware internally. Only with a specific third-party case or adapter, it becomes compatible.

3. Will Using a Wireless Charging Adapter Void My iPhone 7’s Warranty?

Using a third-party wireless charging adapter generally won’t void your iPhone 7’s warranty unless the adapter causes damage to the device. However, Apple is not responsible for any issues arising from the use of unofficial accessories.

4. Is Wireless Charging Faster Than Wired Charging on an iPhone 7 (with an adapter)?

Typically, wireless charging (even with an adapter) is slower than wired charging on an iPhone 7. Wireless charging inherently involves some energy loss during transmission, making it less efficient.

5. Can I Use a Wireless Charging Pad Designed for Newer iPhones with an iPhone 7 Adapter?

Yes, if you have a wireless charging adapter installed on your iPhone 7, you can use any Qi-compatible wireless charging pad. The charging pad doesn’t know or care what specific model of phone is placed on it, as long as it receives the signal through the adapter.

6. Does Wireless Charging Damage the iPhone 7’s Battery?

Wireless charging, in general, doesn’t inherently damage a phone’s battery more than wired charging if done correctly. Excessive heat is the primary culprit for battery degradation. Choose reputable chargers and avoid using your phone intensely while wirelessly charging to minimize heat generation. However, with third-party adapters, using poor quality adapters can lead to overheating and damage the battery.

7. Are There Any Downsides to Using a Wireless Charging Case for iPhone 7?

Yes, some potential downsides include:

Added Bulk: Cases can significantly increase the size and weight of your iPhone 7.
Reduced Lightning Port Access: The case might make it difficult to use the Lightning port for other accessories while charging.
Potential Heat Build-up: Some cases might trap heat during charging.

8. Where Can I Buy a Wireless Charging Adapter or Case for My iPhone 7?

You can find wireless charging adapters and cases for the iPhone 7 on major online retailers like Amazon, eBay, and from various electronics accessory brands. Do some online research for reputable sellers.

9. What’s the Difference Between Wireless Charging and Fast Wireless Charging?

Wireless charging refers to the general technology of transferring power wirelessly. Fast wireless charging utilizes higher power outputs to deliver a faster charging speed. It requires both a compatible phone (which the iPhone 7 with an adapter might not fully support) and a fast wireless charging pad (which may deliver more power than is safe for the battery, if not regulated by the phone).

10. Can I Use Wireless Charging with a Metal Case on My iPhone 7 (with an adapter)?

No, metal cases generally block wireless charging. The electromagnetic field cannot penetrate metal, rendering the charging process ineffective. You’ll need a non-metallic case or no case at all.

11. Are All Wireless Chargers the Same?

No, wireless chargers vary in terms of charging speed, features, and build quality. Look for chargers that support the Qi standard, have safety certifications, and offer the wattage (power output) you need.

12. What iPhone Models Support Wireless Charging Natively?

Apple introduced native wireless charging (Qi-compatible) starting with the iPhone 8, iPhone 8 Plus, and iPhone X. All subsequent iPhone models (iPhone XS, iPhone XR, iPhone 11 series, iPhone 12 series, iPhone 13 series, iPhone 14 series, and iPhone 15 series) also support wireless charging.

Conclusion

While the iPhone 7 doesn’t natively support wireless charging, you can add this functionality using third-party accessories. However, be mindful of the potential trade-offs in terms of charging speed, aesthetics, and potential risks. Ultimately, the decision to add wireless charging to your iPhone 7 depends on your individual needs and preferences. If you prioritize convenience and are willing to accept slightly slower charging speeds, it can be a viable option. Just remember to choose your accessories carefully and prioritize reputable brands.
