RugOne Xever 8 review: An extremely rugged phone with a replaceable battery, but it's not quite the next-generation device I hoped for

by · TechRadar

TechRadar Verdict

In some ways, this is better than the Xever 7 Pro, and in others, the Xever 8 falls short of being truly next-generation. Providing a dual-service charger and two batteries at this price is compelling, but this phone needed a more contemporary SoC that supported 5G to seal the deal.

Pros

  • +Extremely rugged
  • +Hot-swappable battery
  • +Decent camera
  • +Easy to carry

Cons

  • -SoC lacks punch
  • -No NPU
  • -Only 4G
  • -2K video

RugOne Xever 8: 30-second review

While this phone won’t make our best rugged phone collection, what it offers might be perfect for some customers, and it is reasonably affordable for a phone with a swappable battery.

RugOne is Ulefone's premium rugged sub-brand, launched in late 2025. It targets buyers who want a genuinely capable device rather than a cheap, rough-and-ready handset. The Xever 8 is the entry point to the second generation of that vision. It arrived in May 2026 and carries forward the headline idea from the Xever 7 series: a battery you can swap without powering down the phone.

That concept matures here into what RugOne calls Swappable Battery 2.0. The claim is that critical apps stay running throughout the swap, and within quite narrow criteria, it achieves that.

I can confirm that the Xever 8 ships with two 4,800mAh batteries and a charging dock in the box. For field workers and outdoor users who simply cannot afford downtime, the proposition is clear.

There is a catch, though, and it is worth addressing upfront. The Xever 7 was a 5G device with a Dimensity 8020 chipset. The Xever 8 steps down to a Helio G200 on a 4G-only platform. For a phone launching in 2026, that is a significant concession, and it, to some degree, negates some of the advantages this phone has over its previous generation. RugOne made a deliberate trade-off, prioritising the battery system and audio hardware over performance. Whether buyers agree that trade is fair depends heavily on what they need most.

With a better SoC, this might have been one of the best rugged phones, but it appears that we might need to wait until the Xever 9 to get all these ducks in a row.
