How much do smartphone models really change from one year to the next?

Although it’s always tempting to imbue past decades with a nostalgia they didn’t deserve at the time, the Noughties was a great period in British history.

This was an era before pandemics, war in Europe or referendums on sovereignty and independence. It was a less fearful time of brave new music, TV and – of course – technology.

The internet powered daily life, but we hadn’t yet descended into social media-fuelled culture wars or a screen-fed tsunami of mental health issues.

Best of all, consumer technology was innovating at an unprecedented rate, from broadband line speeds and multimedia filetypes to the emergence of the iPad and flatscreen TVs.

Smartphone evolution also occurred at a breakneck pace across the decade. The BlackBerry, iPhone and Android OS all arrived and became huge success stories.

It felt as if each annual handset cycle heralded new innovations – colour screens, larger displays, fully capacitive touchscreens, huge improvements in processing power, and so forth.

By contrast, today’s smartphone evolution has slowed to a crawl.

AI has been the one major innovation of recent years, and it’s increasingly running aground in an ocean of incorrect reporting, copyright concerns, technical flaws and unmet hype.

As a consumer, the smartphone remains an essential daily tool, but are annual product updates really enough to justify trading in or upgrading your handset on a regular basis?

That’s not very smart

Since the mid-2010s, smartphones have been capable of doing anything consumers require, from capturing high-resolution images to facilitating online gameplay through apps.

Screens were big enough to use one-handed and bright enough to function in all weathers, while IP68 protection and shatterproof screens added welcome durability.

Batteries lasted a day or two without charging (as now), CPUs could support multiple applications simultaneously (as now) and handsets were all generic rectangles (as now).

Ever since, smartphone evolution has involved tinkering in the margins, rather than heralding new innovations or exciting features.

Yet while device manufacturers depend on regular handset replacement to maintain their profits, are there significant benefits from a consumer perspective to upgrading your phone?

Failed creations

Even when smartphone manufacturers have tried to innovate in the last decade, the results have often been disappointing.

Folding phones foundered on a sea of dead pixels and snapped hinges, while devices like the Amazon Fire Phone proved consumers didn’t want to abandon the Android/iOS duopoly.

Dual-screen handsets proved confusing, and the attempts by smart watches to encroach into smartphone territory have consistently been hobbled by their diminutive screen sizes.

Because smartphones already do everything we need, annual update cycles are by definition tokenistic – more nits or pixels, a slightly faster processor, etc.

None of this will persuade an owner of last year’s handset to sacrifice hundreds of pounds in depreciation and upgrade to a marginally better new version.

This is especially true since those differences may only be noticeable if you positioned both handsets side-by-side and ran identical tasks on them, which nobody other than tech reviewers would ever do.

When the Samsung Galaxy S26 launched in late February, its one real innovation was a display which is hard to read unless the handset is directly in front of your face.

Similarly, the iPhone 17 was more notable for offering extra storage without extra cost than its adoption of a slightly faster A19 processor or an improved selfie camera compared to the outgoing 16.

As such, and in acknowledgement of these harsh economic times, our advice would be to retain your existing handset as long as you can.

If it’s slow, delete unwanted apps, or upgrade your home broadband to improve its indoor performance, which will benefit other home devices too.

Fit a rubberised case and a screen protector, charging the battery once it drops to 20 per cent to minimise its degradation over time.

With some new Google, Apple and Samsung handsets costing £2,000 apiece, the case for upgrading a fully functional older device simply doesn’t add up, particularly in today’s economic climate…
