Throttling is relative to your computer's capabilities […] DevTools can't truly simulate the CPUs of mobile devices, because the architecture of mobile devices is very different from that of desktops and laptops[^2]. Nor can a slowdown multiplier reproduce a phone’s available memory, storage performance, thermal behaviour, scheduler, background processes, or power-management decisions, so, again, you’re working through a very crude proxy. In fact, in three notable projects since last year’s piece, I found myself using—and getting markedly different results on—a physical device than I do in DevTools. ## Real Low- and Mid-Tier Mobile Devices for 2026

what do users have?and
what should I buy now?For a new purchase in 2026, I’d favour the A17. It occupies the same £199 launch position, is currently ranged, has a longer useful life ahead of it, and had already reached fifth place globally within months of launch. ### The Galaxy A07 4G Complication There is one solid argument _against_ the A17: the Galaxy A07 4G ranked **fourth** in Q1 2026, making it the world’s best-selling Android handset in Counterpoint’s table[^1]. Its sales contribution was particularly strong in the Middle East, Africa and Latin America. That makes the A07 arguably a more realistic floor for sites with a large audience **in those regions**. Still, I would not replace the A17 with it as the single global default. The A07 4G is less far-ranged across the UK, Europe, and North America, while the A17 gives us a more reproducible cross-regional baseline. But this is precisely why one global recommendation will always be a compromise. If your analytics lean heavily towards emerging markets, add the A07 4G as a **regional entry-tier device below the A17**. Your users are more important than broad averages, _especially_ if they’re coming from emerging economies. ## Real Mid-Tier Mobile for 2026: Samsung Galaxy A56 5G
how likely is it that folk actually have one of these?as we are going to get. The hardware also provides a credible step above the A17 without drifting into flagship-lite territory: * **Release date:** March 2025 * **Cost at release:** £499 UK for the consumer 8 GB / 256 GB model * **Chipset:** Exynos 1580 * **Memory:** 8 GB * **Storage:** 128/256 GB; Notebookcheck’s tested 128 GB unit used UFS 3.1 * **Screen:** 6.7″ Super AMOLED, up to 120 Hz * **Support window:** up to six OS/One UI generations and six years of security updates * **Why it’s representative:** mass-market reach, exceptional European sales evidence, global top-ten placement, and a material hardware step above the A17 Notebookcheck’s 128 GB test unit used UFS 3.1 storage and scored 12.0 runs per minute in Speedometer 3 under Chrome 134[^4]. The faster processor, double the recommended RAM, and materially quicker storage give you a useful contrast with the A17—not just in raw benchmark throughput, but in cache access, memory pressure, and the amount of main-thread work the device can absorb before the experience deteriorates. ### Why Not the Galaxy A57 5G? Because **newest is not the same as most representative**. The Galaxy A57 5G arrived in the UK on 10 April 2026, starting at £529 for the 8 GB / 256 GB model[^11]. As of 21 July 2026, that gives it only a little over three months of market history. It may well become the obvious mid-tier recommendation in time, but it does not yet have the A56’s installed-base or sales evidence. This is absence of evidence, not evidence that the A57 is unpopular. If authoritative sales data later shows it displacing the A56, the recommendation should change. But picking it today would reward catalogue freshness over the very thing we are trying to measure: the hardware people actually use. The A56 is not the recommendation despite being one generation old. It is the recommendation because the market has already proved it representative. ## What About WebPageTest Equivalents? WebPageTest’s open-source configuration does list its emulated devices. Each preset is a small configuration of viewport width and height, device pixel ratio, user agent, and a `throttle_cpu` multiplier[^12]. That gives us something a little more useful than inferring from the names shown in the device dropdown. The closest presets I would use are:
| Physical device | Closest WebPageTest preset | WebPageTest settings |
|---|---|---|
| Galaxy A17 5G | Google Pixel 5 | 393 × 722 CSS px; DPR 2.75; 2× CPU slowdown |
| Galaxy A56 5G | Google Pixel 6 or Pixel 7 | 412 × 786 or 412 × 783 CSS px; DPR 2.63; 1× CPU slowdown |
