Will This Case Fit My Phone?
If there is one question that is always asked by a visitor to a phone case eCommerce site, it is “will this case fit my phone”.
Customers are not always well educated about their phone model. They may know they have an iPhone, but not which model or size. They may know they have an Android, like the Samsung Galaxy S22. But they may not remember if the phone model is a S22, the S22+, or the S22 Ultra.
Wouldn’t it be great if your website could instantly answer that question and curate phone case options for that customer? Customer satisfaction and sales conversion goes through the roof!

Get the Exact Model and Size of iPhone, Android Phones
ScientiaMobile puts all of this device detection within reach with a simple JavaScript snippet. Check it out here. By loading WURFL.js, you can tap into ScientiaMobile’s library of over 95,000 devices and the most accurate device detection solution in the industry.
Every week, ScientiaMobile updates its library, so you will alway be ready for recently released models.
Phone case vendors can map the model names of the visiting customer’s smartphone to the phone cases in your inventory. Instantly, a customer can know which cases will fit his/her phone, and whether colors and designs are available.
Home-grown and open-source solutions are notoriously inaccurate, so it is best to go with a solution that is known to be accurate. WURFL is trusted by leaders like Google and Amazon.
And many phone case websites use WURFL.js today for precisely this use case.
Identify Valuable iPhone Model Users
Distinct iPhone models are particularly challenging to identify correctly. Yet iPhone owners are exactly the kind customers you want to help. iPhone users have 40% higher annual income and have a 4X higher check out bill than Android users. Delighting iPhone customers with great online sales assistance provides a great ROI.
WURFL.js accurately identifies iPhones. And with this information, you can identify affluent early adopters. For example, WURFL.js can instantly identify and distinguish between:
- Apple iPhone 14
- Apple iPhone 14 Pro
- Apple iPhone 14 Pro Max
- Apple iPhone 14 Plus
Customize and Go Deep with Phone Model Details
Not only will WURFL.js return the exact device model, but with some customization, it can provide all sorts of relevant physical information, like:
- physical_height – Device height measured in millimeters
- physical_thickness – Device thickness measured in millimeters
- physical_width- Device width measured in millimeters
WURFL.js can also help categorize the phone in interesting ways. For example, WURFL.js can provide analytics by the various brands of smartphones.
brand_name – e.g. Samsung or Apple
Likewise with new physical form factors like foldable phones, tracking the different physical form factors is important. For example, the WURFL device capability physical_form_factor returns a number of categories, including:
- phone_bar: Classic feature phone with physical keypad (including devices such as RIM/Blackberry with full qwerty keyboard)
- phone_clamshell: Foldable, typically screen on one part and keypad on the other. Typical for classic feature phones.
- phone_foldable_booklet: A phone that folds along the vertical axis
- phone_foldable_clamshell: A phone that folds along the horizontal axis
- phone_phablet: Same as phone_slate, but with screen size between 5.3 to 6.9 inches. Must be able to make phone calls.
How Does WURFL.js Work and Return Phone Information?

ScientiaMobile operates WURFL.js as a Cloud-based service. By placing a single JavaScript snippet on your webpage, WURFL.js responds with a JavaScript object containing the WURFL Device Capabilities you want. For example complete_device_name provides a concatenation of brand name, model name and marketing name (where available) of a device into a single string.
ScientiaMobile offers several WURFL.js plans based on traffic to your website (Basic, Standard, Pro) that include iPhone detection. In addition, ScientiaMobile offers customization of different WURFL device capabilities than the standard set. Likewise, customers who need more privacy and control can opt for ScientiaMobile’s WURFL.js Private Cloud.
Load Your Phone Case Website Faster with Image Optimization
The phone case market is highly competitive. You don’t want to lose potential customers because your website loads slowly – particularly on mobile phones. Studies show that 53% customers will abandon a site if it does not load in under 3 seconds.
One of the biggest causes of slow website loading is images that are too large. Images account for roughly 60% of a website’s payload. Most of the time these images are far larger than they should be for a good mobile phone experience. For example, one leading phone case ecommerce website had over 6MB of images to download on their homepage!
These images look great. But with an image CDN like ScientiaMobile’s ImageEngine, the images can be instantly tailored to the exact device model. That’s right. The same technology in WURFL.js that detects device models is used to resize, compress, and convert file formats for images into their most optimized version.
Then they are stored in a worldwide CDN for instant, fast loading. The result is that 6MB of phone case images is reduced to only 719k. And all of this is done with no perceptible loss of visual quality.
Smaller images means faster page loading and higher sales conversions. ImageEngine’s Test My Site tool indicates the phone case site with 6MB of images would load more than 5 seconds faster! This speed improvement definitely keeps more buyers around.

Improve the SEO of Your Phone Case Website with Image Optimization
Another benefit of image optimization is that SEO improves. Google takes into account pagespeed and web performance when determining ranking for phone case websites. Optimizing images can push phone case ecommerce sites onto the first page because it accelerates page loading up to 60%.
