Nobody relishes the idea of waiting for content to load. It’s a moment that feels even longer than it actually is, leading to inevitable sighs of frustration. At Twin Prime, we embrace the mantra of speed and dedicate our resources to eliminate the sight of the all-too-infamous spinning wheel. Utilizing our Global Location-based Acceleration Strategies (GLAS) database, we’ve analyzed and processed billions of network requests from all over the globe. This has provided us a unique perspective on network performance and allowed us to pinpoint the factors that impact it. Understanding these factors is crucial in mitigating mobile performance issues, and our findings showcase the role of variability in shaping mobile performance.
In our inaugural report, we delved into a staggering half a billion requests from 100 countries, involving 200 carriers and a thousand different types of devices. Our analysis focused on three main attributing elements to variability – the Network, the Device, and the App.
1. **Debunking the Wi-Fi Speed Myth**
A commonly held belief is that Wi-Fi trumps cellular networks when it comes to reliability and speed. To evaluate this claim, we compared the performance of Long Term Evolution (LTE) and Wi-Fi on iPhone 6 devices throughout multiple cities. These devices were running identical iOS versions and were downloading same-sized images through the same app.
Our data paints a different picture. In every city we analyzed, Wi-Fi exhibited longer download times for 200-250KB files as compared to LTE. Visualizing the difference in download times, it’s clear that Wi-Fi falls behind LTE in many cases. Perception-wise, speed differences of 200 milliseconds are known to be noticeable, and multiples of 200 end up being especially discernible.
Modern cellular networks, contrary to popular presumption, are often notably faster than Wi-Fi. In cases where Wi-Fi takes the lead, the degree of advantage is often minimal.
2. **Exploring the Impact of Devices**
There exists a multitude of mobile devices, boasting varying performances. We found proof of this when comparing download speeds on iPhone 6 devices using the same carrier (AT&T LTE) in the same city (Philadelphia), running an identical app and downloading similar file sizes. The significant speed difference was simply accounted for by the slight variance in the devices’ iOS versions.
The variability in user experiences cannot be overstated. A one-size-fits-all strategy is not feasible when dealing with a vast spectrum of device types.
3. **Decoding the Role of the App**
Performance, as expected, varies within an app based on the type of content. Different strategies are necessary to optimize the loading of large files compared to their smaller counterparts. While smaller files are expected to download faster, in reality, there’s little difference in perceived download times across a range of file sizes, according to our data.
Finally putting it all together, popular perceptions are often misguided due to the intricate factor of variability. It’s not as simple as just optimizing your app for locations with poor network performance, nor does solely focusing on app-based improvements guarantee universal efficacy. The overwhelming variability in mobile commands a more nuanced approach, a realization that honours the role of individual variables like the user’s device and location.
Recognizing this variability is the first step. Twin Prime helps you take the second with GLAS technology, masterfully navigating optimizing mobile app performance by intelligently detecting, analyzing, and strategizing based on these variables.
