Amazfit T-Rex 4: Release Date, Specs & The Real Story Nobody’s Telling You

I’ve owned every T-Rex from the T-Rex 2 onwards. I hiked with the T-Rex 3 in the Himalayas last October. I’ve been running with the T-Rex 3 Pro since it launched. So when people ask me about the T-Rex 4 — and trust me, I get asked a lot — I don’t just throw rumor lists at them.

Here’s what I actually know, what I think is likely, and the one question that matters most right now: should you buy a T-Rex today or hold off?

The Amazfit T-Rex 4 doesn’t have an official release date yet — but Zepp’s Q4 2025 earnings call changed the picture completely. More T-Rex models are confirmed for 2026, the T-Rex 3 is entering its final update cycle, and the Ultra 2 just launched at $549 in February. That’s a lot of moving pieces.

Let me break it all down so you can actually make a decision.

First — The T-Rex Lineup Just Got Complicated

Before we talk about T-Rex 4, you need to understand what happened in February 2026, because it reshapes everything.

Amazfit launched the T-Rex Ultra 2 at $549.99. Titanium bezel, Grade 5 titanium case back, 1.5-inch AMOLED at 3,000 nits, 870 mAh battery rated at 30 days, full-color offline maps, dual-band GPS, 10 ATM water resistance, dual-mode flashlight with green night-vision mode. It competes directly with the Garmin Fenix 8 at roughly half the price.

That launch split the T-Rex line into two clear tiers. The Ultra 2 owns the $500+ premium segment. A future T-Rex 4 would sit in the $250–$330 range — the true successor to the T-Rex 3.

These are different watches for different people. Don’t confuse them.

If you’re eyeing the Ultra 2 and wondering how it compares to the current mid-range options, our Amazfit T-Rex 3 vs T-Rex 3 Pro breakdown gives you the full context on where the existing lineup sits.

When Is the T-Rex 4 Actually Coming?

No official date. But there’s enough evidence to make a confident guess.

Here’s the T-Rex release history:

The T-Rex 3 launched September 2024. Amazfit’s two-year pattern puts T-Rex 4 squarely in September–October 2026.

There’s a second signal that backs this up. Zepp Health’s CFO confirmed in the Q4 2025 earnings call that roughly nine new Amazfit products are planned for 2026 — and specifically mentioned that “more products will join the T-Rex family.” The Ultra 2 is already out. At least one more T-Rex is coming before December.

What if it slips? CES 2027 in January would be the backup window. But I’d bet on September 2026. Amazfit has anchored the T-Rex line to IFA Berlin timing twice now — T-Rex 3 launched at IFA 2024.

One more thing worth knowing: Zepp confirmed the T-Rex 3 will receive its last major software update in September 2026. That’s not necessarily a bad sign — it’s how Zepp’s end-of-life policy works, devices get two years of updates. But it does signal that Zepp considers the T-Rex 3 generation complete. T-Rex 4 is next.

What Will T-Rex 4 Actually Look Like?

No confirmed leaks as of June 2026. So I’m not going to pretend otherwise.

What I can do is look at what changed T-Rex 2 → T-Rex 3, and what the Ultra 2 introduced at the flagship level — because Amazfit’s pattern is clear: premium features trickle down to mid-range within 12–18 months.

The single biggest upgrade I expect: full-color offline maps.

The T-Rex 3’s maps are limited color. The Ultra 2 launched with full-color preloaded global maps, offline rerouting, and point-of-interest search without any network. That’s the feature gap that matters most for trail runners and hikers. By the time T-Rex 4 arrives, this will be the standard expectation at the mid-range price.

I’ve been using offline navigation on the T-Rex 3 Pro for months — it’s good, but the map detail is genuinely lacking compared to what the Ultra 2 shows. If T-Rex 4 closes that gap, it’ll be a meaningful upgrade. See how the current navigation works in our complete T-Rex 3 Pro navigation guide — that’s the baseline T-Rex 4 would be improving on.

Here’s what I realistically expect across the board:

What won’t change: The Grade 5 titanium construction stays with the Ultra 2 — that’s its differentiator at $550. The 870 mAh battery stays up there too. T-Rex 4 will be polymer build, which is fine — the T-Rex 3 is genuinely tough despite not being titanium.

T-Rex 4 vs T-Rex 3 — Will the Upgrade Actually Matter?

This is the question I get most. Let me be honest about it.

T-Rex 2 → T-Rex 3 was a meaningful jump. Display went from MIP to AMOLED — that’s night and day. Battery improved by 4–5 days. Dual-band GPS arrived. Offline maps were introduced for the first time. That’s the kind of generation leap that makes upgrading obvious.

T-Rex 3 → T-Rex 4 will probably be smaller. When a generation introduces something transformative (AMOLED, dual-band GPS), the next one refines rather than reinvents. I expect better maps, slightly better sensors, a larger screen, maybe a flashlight. Those are real improvements but not jaw-dropping ones.

My honest take: If you own a T-Rex 3 and you mainly use it for everyday fitness tracking, gym sessions, and road running — T-Rex 4 won’t change your life. If you do serious trail navigation and maps are a pain point for you, T-Rex 4 is worth waiting for specifically for the full-color map upgrade.

We tested Amazfit’s current GPS performance in depth in our real-world GPS accuracy test — worth reading if navigation is your main reason for considering an upgrade.

What’s the Expected Price?

Based on the T-Rex pricing history, Amazfit needs to keep clear distance between T-Rex 4 and the Ultra 2 at $549.

The T-Rex 3 launched at $229. The T-Rex 3 Pro launched at $299. Those price points are anchored now.

My best guess: T-Rex 4 at $249–$269, T-Rex 4 Pro at $329 if Amazfit follows the same dual-model strategy again.

The one thing Amazfit is extremely consistent about: aggressive value positioning. When T-Rex 3 launched at $229, the Garmin Instinct 2 was $299 with a worse display. Expect T-Rex 4 to pull the same move against whatever Garmin has at that price point in late 2026.

Should You Wait for T-Rex 4 — or Just Buy the T-Rex 3 Now?

This is the real decision. Here’s how I actually think about it.

Buy the T-Rex 3 or T-Rex 3 Pro today if:

You need a watch in the next 1–3 months and can’t wait. The T-Rex 3 at $229 is still excellent — dual-band GPS, AMOLED display, offline maps, 20+ day battery. It doesn’t suddenly become a bad watch because a successor is coming.

The T-Rex 3 Pro at $299 is what I’d actually recommend to most people right now. The LED flashlight is more useful than it sounds, the battery is better, and it’s the most refined version of this generation. Read our full T-Rex 3 Pro review if you’re considering it — that’ll tell you exactly what you’re getting.

Wait for T-Rex 4 if:

Your current watch is working fine and maps/navigation is a real pain point for you. Full-color offline maps are probably the biggest T-Rex 4 upgrade, and if that’s what you care about, holding three to four months is worth it.

You’re upgrading from a T-Rex 2 or older. In that case the gap will feel significant regardless.

What about the Ultra 2?

If your budget stretches to $549 and you do serious multi-day outdoor stuff — trail ultras, extended hikes, anything where 30-day battery matters — the Ultra 2 is available now and it’s genuinely excellent. T-Rex 4 will not match its titanium build or battery. Those are Ultra 2 exclusives.

Where T-Rex 4 Will Compete With Garmin

When T-Rex 4 launches, its primary fight will be with the Garmin Instinct 3 series.

The pattern from T-Rex 3 vs Garmin Instinct 2 is likely to repeat:

T-Rex 4 will probably win on: Display (AMOLED vs Garmin’s MIP), price (likely $80–$120 cheaper), battery in GPS-on mode (Amazfit is consistently strong here).

Garmin will probably still win on: Training analysis depth — VO2 Max tracking, training load, recovery advisor. The Connect IQ app ecosystem. Software polish and reliability.

If you’re already in the Garmin ecosystem and rely on those training metrics, honestly stay there — the ecosystem lock-in is real. If you’re coming in fresh and care about screen quality and getting the most hardware for your money, T-Rex 4 will be hard to beat at its price.

My Honest Take

I’ve been watching Amazfit for five years. They don’t miss their T-Rex release windows by much.

T-Rex 4 is coming — probably September 2026 at IFA, possibly earlier. When it lands, full-color maps will be the headline feature and the price will undercut Garmin Instinct by a meaningful amount. That’s just how Amazfit plays it every time.

If you’re on the fence right now: buy the T-Rex 3 Pro at $299 and don’t look back. It’s the best version of this generation and it’ll serve you well for 2–3 years. If you can wait until October and maps matter to you, wait.

What I wouldn’t do is sit on an old or broken watch waiting indefinitely. The T-Rex 3 Pro is a genuinely good piece of kit. Use it.
