Testing Methodology and Criteria

Our review process is designed to simulate real-world conditions as closely as possible. Is there any other way to do a review? Every product we test we buy ourselves so you can be assured that we’re not trying to push one product over another. Here’s our testing methodology and the criteria we use to evaluate each product:

Installation: We evaluate how easy it is to install the screen protector without bubbles or misalignments using the tools provided by the manufacturer. Companies that provide better install tools like large dust stickers, electronic wipes, and install frames will score higher. A screen protector that is straightforward and minimizes dust during installation gets a higher score.

Scratch Resistance: We test the scratch resistance of the screen protector by using the Mohs hardness scale. We start with a level 2 pick (equivalent to a fingernail) and increase the level until we see visible scratches on the protector. Screen protectors that resist scratches longer score higher. This is one of the last tests we do in our destructive testing portion.

Impact Resistance: There are two parts to impact resistance: direct impact and edge. For direct impact, we measure the force required to break the screen protector at 90 degrees using a metal punch. For the edge, we take a flat metal punch and put pressure on the edge at a 15-degree angle. Screen protectors that take more effort to break score higher.

Oleophobic Coating: We test the screen protector’s oleophobic resistance to fingerprints and face grease. The better a screen protector’s coating is at resisting fingerprints and smudges, the higher its score. We measure this by tracking how long a droplet of water takes to travel 7 inches at a 45-degree incline.

Extra Features: Certain companies will promote blue light reduction features or anti-static adhesives. Other companies will have warranties that allow you to keep replacing the screen protectors for free. Companies with features/warranties that are unique will score better.

Coverage: We check how well the screen protector fits the screen and determine how much it covers the entire front surface of the phone. The closer the screen protector is to the size of the iPhone screen, the higher the score.

Price vs. Value: We compare the price of the product with the features it offers. From our experience, the $20 to $50 dollar screen protector range is filled with companies that offer poor products at high prices. If a screen protector delivers top-notch performance without breaking the bank, it’s a big win in our books!

The final score is based on each test group. We rank each product in each category and sum up the final standings. The products with the lowest combined score are the best. For this round, we’ve weighted each category equally though certain categories will lend themselves to be less important (i.e the extra features).

Frequently Asked Questions About iPhone Screen Protectors (FAQs)

Do I really need a screen protector for my iPhone 14?

While the iPhone 12, 13 and 14’s do have a feature called Ceramic Shield which greatly improves impact protection, scratches will still be an issue. Based on our testing, the latest iPhones will scratch just as easily as before. Using a screen protector will prevent your iPhone’s screen from permanent scratches. In general, a screen protector is a relatively small investment that can prevent more costly repairs in the future (especially if you’re out of warranty).

How often should I replace my screen protector?

The frequency of replacement really depends on the quality of the screen protector and how much wear and tear it experiences. As a rule of thumb, we’d recommend to replace a screen protector if there is a crack. We wouldn’t worry much about scratches but if your protector is scratched enough, cracks will definitely occur if you drop your device. If your screen protector starts chipping or peeling off your device, it’s a clear sign to replace it right away. Do you seriously want to deal with glass shards everywhere?
If you do end up with a cracked/chipping screen protector, using clear packing tape is a good way to tide you over until you can get a replacement

Are glass screen protectors better than plastic ones?

Glass screen protectors typically offer better clarity and feel more like the original screen than plastic ones. They also tend to be more scratch-resistant as most glass will scratch at a hardness of 7 on the Moh’s scale. Plastic screen protectors will scratch around 3. However, glass protectors can shatter upon impact, whereas plastic protectors are more likely to just scratch.

Will a screen protector affect the touch sensitivity of my screen?

Most screen protectors are only 0.33mm thick with a thin layer of adhesive. We haven’t come across any screen protectors in the last few years that reduced the sensitivity of the iPhone (even the cheap ones). The only time we had an issue was when we were playing around with using two screen protectors. The lag with two screen protectors was quite noticeable.

Can I install a screen protector myself or should I have it professionally installed?

You should be able to install a screen protector by yourself if you’ve purchased a good one (check out the Top 5 above). Reputable companies will include tools like install frames fitted to your specific device, non-alcoholic wipes and large dust stickers to ensure a dust-free/bubble free installation. However, if you’re uncomfortable with doing it yourself, we’ve seen many mall kiosks offer the service (though you won’t know the quality of glass you’re getting) or you could goto the Apple Store and buy a Belkin product

What’s the deal with screen protector prices? Why are some so much more expensive?

The price of a screen protector can vary based on the quality of the materials used, the brand, and any additional features like anti-glare or blue light filtering technology. That said, a higher price doesn’t always mean a better product, check out your YouTube channel if you want to know the difference between cheap and expensive screen protectors

How to Choose the Right Screen Protector

In general, when it comes to screen protectors, you get what you pay for. Cheaper products (like an Amazon 3-pack will) may seem like a good deal but you will be replacing the screen protectors often (that’s why there is 3 of them!). From our perspective these cheap protectors will be great for people who constantly drop their devices. If it breaks, put a new one on!
For those who are a bit more discerning with their devices, getting a more expensive one like a sapphire protector may be worth it because it will keep your iPhone looking scratch free as long as you don’t break it BUT they are expensive.

Installation Tips

Screen Protector Installation Steps

Preparation: Switch off your furnace or central air to reduce dust. If you own an air purifier, let it run for a while. Keep your pets away from the area. Some people suggest running a hot shower to let dust settle, but your mileage may vary.

Clean Install Area: Make sure your workspace is tidy, well-lit, and free of dust. A quick wipe down with a microfiber cloth should do the trick.

Personal Hygiene: Wash your hands thoroughly. You don’t want oils from your hands getting onto your screen.

Device Preparation: Remove any case from your device and clean it with a damp cloth. If you’re replacing a damaged screen protector, cover it with packing tape before removal to avoid scattering glass shards.

Read Instructions: Understand your screen protector’s installation instructions before starting. If it doesn’t come with an installation frame, practice aligning it with your device to get a feel for the correct positioning.

Pre-Install Clean: Before beginning the installation, use a lint roller or painter’s tape to eliminate as much dust as possible from your device.

Installation: Follow the manufacturer’s instructions for installation. If no instructions are given, remove the adhesive backing, align the protector based on your practice run, and lower it slowly onto your device. Press out any bubbles.

Post-Install Check: Celebrate if your screen protector is installed without dust. If dust is present, or if there are bubbles, don’t despair. More expensive brands often provide better installation tools and dust-resistant adhesive.

Troubleshooting: Bubbles along the edges usually resolve themselves after a few days. If there’s dust or bubbles in the middle, remove the protector carefully without bending it. Use a dust sticker to pick up the dust, then reinstall the protector.

Repeat If Necessary: Continue this process until all dust is removed. Be aware, after a couple of attempts, you might find more dust appearing on your protector.

Remember, these steps aren’t typically shared by screen protector companies as they might want you to purchase more protectors. Following these steps might eliminate the need for replacement protectors.
