OnePlus Watch 2R

What Reviewers Agree On

Class-leading Wear OS battery life — a dual-chipset (Snapdragon W5 Gen 1 + BES2700) design gives ~3-4 days of real use, far beyond Pixel/Galaxy Wear OS rivals
Genuinely fast charging for a smartwatch — roughly 0-100% in ~50-65 minutes and a 10-minute top-up for about a full day
Excellent value at ~$229 (often $175-200 on sale) — close to flagship functionality for a fraction of the price
Lightweight, comfortable aluminium build (~25% lighter than the Watch 2) with IP68 + 5ATM and standard 22mm straps
A clean, responsive Wear OS 4 experience with the liked 'Bubbles' app interface — better than its early reputation

Detailed Comparison

Battery & Charging

OnePlus Watch 2R

The headline strength. The dual-chipset design makes this the longest-lasting Wear OS watch — 3-4 days real-world against OnePlus's 100h smart / 48h heavy / 12-day power-saving claims — and it recharges in about an hour.

OnePlus claims up to 100 hours in Smart Mode, 48 hours heavy use, and 12 days in power-saving mode from the 500mAh cell.
Real-world: ~3 days with the always-on display off and lift-to-wake — closer to 4 days light, not quite the 100h claim without battery-saver tweaks.
Hands-on: hit ~90 hours in Smart Mode with brightness near max before being forced into battery-saver — the longest battery life of any Wear OS watch tested.
Day test: 100% in the morning, a gym hour plus heavy Google Maps walking, and it still had ~62% the next morning.

Samsung Galaxy Watch 7

What Reviewers Agree On

New 3nm Exynos W1000 chip — a genuine performance jump over the Watch 6's Exynos W930.
Dual-frequency GPS — new for the standard Galaxy Watch; more accurate tracking.
BioActive sensor with the new AGEs Index — biological-age estimation via a skin scan.
3,000-nit display — bright and readable outdoors, with Sapphire Crystal protection.
Wear OS 5 + One UI 6 Watch + Galaxy AI — Energy Score, Wellness Tips, a polished software stack.
Android Authority's verdict: 'Samsung forgot about the Galaxy Watch 7, but I still think you should buy it.'
$299 (40mm) / $329 (44mm) launch — fairly priced for a flagship Wear OS watch.
5 ATM + IP68 + MIL-STD-810H — full Galaxy Watch durability ratings.

Deal Breakers

Battery life drew criticism — Engadget notes 'many people were disappointed in its battery life.'
Design carries over from the Watch 6 — no rotating bezel (there was no Classic in this generation).
Raised glass screen can be easily damaged — Engadget flags this fragility.
Best inside the Samsung ecosystem — AGEs Index and ECG are tied to a Samsung phone.
Android-only — no iOS compatibility.
Overshadowed at launch by the Galaxy Watch Ultra, and since superseded by the Galaxy Watch 8.

~30 hours typical use, 425mAh (44mm) / 300mAh (40mm). Battery drew criticism — many owners found it underwhelming. Wireless fast charging.

Battery drew criticism — Engadget: 'many people were disappointed in its battery life.'
~30 hours typical use — similar to the Watch 6; the 44mm (425mAh) outlasts the 40mm (300mAh).
The new 3nm Exynos W1000 chip improves efficiency — but not enough to fully address the battery complaints.
Wireless fast charging — a quick top-up before bed enables overnight sleep tracking.
The Galaxy Watch 8 later addressed the battery complaints with a larger cell — confirming the Watch 7's was a known weak point.

Value vs Competition

OnePlus Watch 2R

At ~$229 (often $175-200 on sale) the 2R is widely called the best-value Wear OS watch — it delivers ~95% of flagship functionality and the platform's best battery, against a Watch 2 that costs more for steel and dual-frequency GPS.

The best budget Android watch tested at this price — frequently discounted a further $50.
Verdict: 'Hey, not half bad' — a genuinely good affordable Wear OS option.
At ~$229 it delivers roughly 95% of flagship-watch functionality (those cost 2-3x) with no significant compromises for everyday use.
Versus rivals at similar money: far longer battery than the Galaxy Watch 7 (40h, ~£289) and Pixel Watch 3 (24h, ~£349), and well beyond an Apple Watch SE (18h).
Versus the Watch 2 (~$299): the 2R felt slightly shorter on battery in real use and trades the steel build for plastic-ier glass — a ~$50-100 saving that doesn't fully justify itself for some.
Two-months-later owner who paid ~$175 at launch (sold a Samsung Watch 4 Classic to switch): confidently worth the money.

Samsung Galaxy Watch 7

$299 (40mm) / $329 (44mm) launch. Now superseded by the Galaxy Watch 8 — a strong value if discounted. Competes with the Pixel Watch and (for iOS) the Apple Watch.

$299 (40mm) / $329 (44mm) launch — fairly priced for a flagship Wear OS watch.
Android Authority's standing recommendation: 'Samsung forgot about the Galaxy Watch 7, but I still think you should buy it' — a strong value pick.
vs Galaxy Watch Ultra (same generation): the Ultra adds a rugged build, a larger battery, and a Quick Button for considerably more money.
Now superseded by the Galaxy Watch 8 — which added a larger battery and the squircle redesign.
Best for: Samsung phone owners who want the faster 3nm chip, dual-band GPS, and the AGEs Index — and find the overlooked Watch 7 discounted.
