Why we keep testing physical products for a full year after launch

First impressions lie. Long-term durability rarely shows up in a two-week review, so we changed our policy: every flagship physical product now gets a 12-month retest before its score is final.

Key takeaways
  • Every flagship physical product now receives a 12-month retest before its score is final.
  • Most durability failures appear between months three and nine.
  • Scores that change after a retest are revised publicly with a dated note.
  • Battery degradation is the single most common long-term complaint we log.

A two-week review tells you how a product performs on its best day. It says almost nothing about how it will behave in month eight, when the finish has worn, the battery has aged and the novelty has gone.

That gap between first impressions and lived reality is why we have changed our policy: every flagship physical product we cover now gets a full twelve-month retest before its score is locked in.

Why two weeks is not enough

In our internal logs, the majority of serious hardware problems did not appear at unboxing. They appeared later — after the honeymoon period, once a device had been carried, charged, dropped and updated dozens of times.

  • Battery capacity usually fades most between months three and nine.
  • Hinges, zips and cable sleeves fail from repetition, not from day one.
  • Software updates often introduce regressions months after launch.
  • Long-term support policies only become visible as time passes.

How the 12-month retest works

Each flagship unit is logged at purchase and revisited on a fixed schedule. Results feed back into the original score rather than sitting in a separate article.

What we measure at each checkpoint

  • Battery runtime against the day-one figure.
  • Physical wear on high-touch surfaces and moving parts.
  • Performance and stability after cumulative software updates.
  • Support and warranty experience if a fault appears.

"Durability is not a feature you can list on a box. It is a promise the product either keeps or breaks, and only time can tell you which."

Rob Kelly, Hardware Lead
What this means for our scores

A score is now provisional for the first year. If a retest changes it, we revise the page and publish a dated note explaining exactly what shifted.

What we learned from the first cohort

The first twelve products through the new process painted a clear picture: most held up well, a few improved with mature software, and a small number degraded enough to lose points. Battery ageing, not breakage, was the most common complaint we logged.

Why we are doing this now

Readers buy products to keep, not to review. Our job is to tell you what a product is like to own, and ownership is measured in months and years, not in the first fortnight.

Frequently asked questions

What is a long-term product retest?
It is a scheduled re-evaluation of a product over twelve months after launch. We re-measure the things that change with time — battery health, wear, software stability and support — and feed the findings back into the original score.
Will scores change after a retest?
Sometimes. A score is treated as provisional for the first year. If a checkpoint shows a meaningful shift — most often battery capacity or software stability — we revise the page and publish a dated note explaining exactly what changed and why.
Which products get the 12-month treatment?
Every flagship physical product we cover is logged at purchase and enrolled in the retest schedule. Each unit is revisited at fixed checkpoints over the following year rather than being reviewed once and left unchecked.
How does this affect the reviews I read today?
Nothing changes about how a product is scored on day one. What changes is that the score is no longer final at launch — it can be revised, with a dated note, once we have real data from months of ownership rather than a two-week trial.
