Amazfit Bip 5 Unity Review: The $90 Smartwatch That Punches Way Above Its Price
Quick verdict: the Amazfit Bip 5 Unity is the smartwatch I’d point most people toward right now if they want a clean fitness tracker that doesnt cost Apple Watch money. Its $90, has a real metal body, lasts about 11 days on a charge, and the screen is genuinely nice. Its not a smartwatch in the “replace your phone” sense, but it does the core stuff (workouts, sleep, notifications, GPS) without making you babysit it.
Spent the last couple weeks wearing one and rotating in my Amazfit Active 2 for comparison. The Bip 5 Unity isnt as featured but its also less than half the price, and theres a real argument to be made for it depending on what you actually want a watch to do.
What Makes the Bip 5 Unity Different
Amazfit’s lineup got a little confusing this year. The Bip 5 Unity is the budget-meets-build-quality entry. Where the Bip 5 has a plastic body, the Unity gets aluminum and a higher quality strap. It feels more expensive than it actually is, which is the whole pitch.
Specs that actually matter:
- 1.91 inch HD AMOLED display, surprisingly bright outdoors
- Aluminum unibody case with curved 2.5D glass
- Built-in GPS (single-band, accurate enough for casual running and biking)
- 11 day battery life with normal use, longer if you turn off always-on display
- 5 ATM water resistance, fine for swimming
- Built-in voice assistant via Bluetooth call relay
- Around 120+ sport modes, most of which you’ll never touch
- Heart rate, SpO2, sleep tracking, stress score, period tracking
What It’s Actually Like to Wear
The screen is the standout. AMOLED at this price still surprises me. Colors pop, blacks are deep, and at 600 nits I can read it in direct Florida sun without squinting. The Active 2 has a slightly better screen but the gap is smaller than the price difference would suggest.
Fit is comfortable. The watch is light enough that I forget Im wearing it overnight, which is the bar for sleep tracking. The included strap is a basic silicone but the quick release pins mean you can swap to a leather or nylon band for $10 to $15 and the watch suddenly looks legitimate.
Battery life claims always make me skeptical but Amazfit usually delivers. I got about 9 days with the always-on display on and GPS workouts most days. Without AOD, you can stretch to almost 2 weeks easy. Charging is fast, about 90 minutes from dead to full.
Workout Tracking
For the price point, the workout tracking is real. The GPS lock is fast (under 30 seconds outdoors), the heart rate sensor keeps up with intervals reasonably well, and the post-workout summary in the Zepp app is detailed enough to actually use.
One real gripe: the GPS is single band, not dual. If you run in dense urban areas or under heavy tree cover, you’ll see the route drift. For suburban running or open trails, its fine. If accurate GPS matters to you, the Active 2 is the smarter pick.
Sport modes are wildly over-counted. They list “120+” but honestly most people use 5: walking, running, cycling, strength training, swimming. The auto-detect for walking and running works.
Sleep and Health
Sleep tracking is where budget Amazfit watches usually punch above their price tag and the Bip 5 Unity is no exception. Sleep stages, sleep score, awakenings, all logged accurately compared to my Oura Ring as a reference. The breathing tracking through PAI score is decent too, though I’ve never figured out exactly what to do with that number.
SpO2 measurements are spot-checks, not continuous, which is fine. Heart rate monitoring is continuous and accurate at rest.
What It’s Missing
- No music storage on the watch itself
- No always on cellular (this is a Bluetooth watch only)
- Limited third party app support compared to Wear OS or Apple Watch
- Voice assistant requires phone proximity
- No NFC payments
If any of those are dealbreakers, this isnt your watch. The Bip 5 Unity is specifically for people who want fitness tracking and basic phone notifications without the smartwatch complexity.
Bip 5 Unity vs Amazfit Active 2
The Active 2 is roughly $170 to $200 depending on the variant. Its got dual-band GPS, brighter screen, more refined software, and slightly better workout tracking. If you take fitness tracking seriously, the Active 2 is the better buy.
The Bip 5 Unity at $90 is the better buy for casual users. You give up some tracking precision and feature polish but you save half the money. If a watch is replacing a Fitbit or being your first tracker, the Bip 5 Unity is more than enough.
Bip 5 Unity vs Apple Watch SE
Apples cheapest watch (SE 2nd gen) is around $250. Its a better smartwatch by every objective measure. It also has 18 hour battery life and locks you into the Apple ecosystem. The Bip 5 Unity is a focused fitness tracker that happens to do basic smartwatch stuff. Totally different products for different people.
Who Should Buy This
- First time smartwatch buyers who dont want to drop $300+ to figure out if they like wrist tech
- Anyone wearing a Fitbit Inspire or Charge who wants a real screen
- Casual runners and gym goers who want workout tracking but dont care about advanced metrics
- People with Android phones who dont want Wear OS battery anxiety
- Anyone who likes the look of premium watches but doesn’t want to spend $200+
Who Should Skip
- Serious athletes who need dual band GPS and HRV tracking
- iPhone users who want full integration (Apple Watch is the obvious pick)
- People who want to leave their phone at home (no cellular)
- Anyone who wants to pay at registers from their wrist (no NFC)
FAQs
How does it compare to the Bip 5 non Unity? Same internals, different chassis. The Unity gets metal and a nicer strap. The base Bip 5 is plastic and about $20 cheaper. Worth the $20 for the build difference in my opinion.
Will it work with my iPhone? Yes, via the Zepp app. iOS integration is more limited than Android (no quick replies, etc) but the basics work fine.
Is the battery really 11 days? With normal use and AOD off, yes. With AOD on and daily GPS workouts, expect 7 to 9 days. Still excellent for the price.
Whats the strap situation? Standard 22mm quick release. Tons of third party options for under $20.
Is it durable? Aluminum case and 2.5D glass have held up fine through a few accidental knocks. Not as bulletproof as a Garmin Fenix but more than enough for daily wear and gym use.
Bottom Line
The Bip 5 Unity is the smartwatch most people don’t realize they want. It looks better than its price suggests, the fitness tracking is honest, and the battery life means you’re not charging another device every night. If you’ve been Apple-Watch-curious but cant justify the cost, this is the budget alternative that doesn’t feel like a downgrade.
