Best Budget Smartwatches Under $150 (2026)

The smartwatch market has a dirty secret: most watches under $150 are fitness bands with a square screen slapped on. They count steps, show notifications, and die by dinner. But a few budget models actually deliver the features people want — reliable heart rate tracking, GPS, decent app ecosystems, and batteries that last longer than a workday.

We tested the most popular budget smartwatches on Amazon, wearing each for at least a week, tracking workouts, checking notification reliability, and yes, timing how long the battery actually lasts. Here are the four worth your money.

Quick Comparison

1. Amazfit Bip 5 — Best Overall

The Amazfit Bip 5 is the budget smartwatch that doesn't feel budget. It has built-in GPS, a bright 1.69-inch AMOLED display, and a 10-day battery life that makes Apple Watch owners weep. The Zepp app is surprisingly competent for tracking workouts, sleep, and daily activity.

What stands out: The AMOLED screen is vivid and readable in direct sunlight — a rarity at this price. Built-in GPS means you can leave your phone at home for runs and still get accurate distance and pace. Over 100 watch faces are available, and you can create custom ones from photos. The PAI health score gives you a single number to track overall fitness instead of drowning in data.

The catch: The Zepp app isn't as polished as Samsung Health or Apple Health. Third-party app support is basically nonexistent — no Spotify, no Google Pay. The plastic build feels a bit toy-like compared to metal-cased watches. Notification replies are limited to quick responses only.

2. Samsung Galaxy Watch 4 (Renewed) — Best App Ecosystem

Here's the move: buy a renewed Galaxy Watch 4 and you get a flagship smartwatch with Wear OS, the Google Play Store, and Samsung Health for under $150. It's the only watch in this price range that runs real apps — Spotify, Google Maps, YouTube Music, and thousands more.

What stands out: Wear OS 3 gives you actual app support, not just notifications. Samsung Health is one of the best fitness tracking platforms available. The rotating bezel (on the Classic model) is the best smartwatch navigation method period. BIA body composition analysis measures body fat, muscle mass, and water percentage — a feature normally reserved for $400+ watches.

The catch: Battery life is the elephant in the room — 1.5 days means nightly charging. It's a renewed unit, so warranty coverage varies by seller. Only works fully with Android phones — iPhone users are out of luck. The Exynos 9110 chip can feel sluggish when opening apps compared to the Watch 6's newer processor.

3. Garmin Forerunner 45 — Best for Runners

Garmin makes the gold standard for running watches, and the Forerunner 45 brings that DNA to a budget price. This isn't trying to be a mini phone on your wrist — it's a focused running and fitness tool that does one thing exceptionally well.

What stands out: GPS accuracy is best-in-class — Garmin's watch-specific GPS implementation consistently beats phone GPS and other budget watches. The Coach feature creates adaptive training plans that adjust based on your actual performance. Battery lasts 7 days in smartwatch mode, 13 hours with continuous GPS. The MIP (Memory-in-Pixel) display is always-on and always readable in sunlight without jacking up battery drain.

The catch: The 1.04-inch screen is tiny compared to other picks. No third-party apps or music storage — it's a Garmin watch, not a smartwatch platform. The plastic resin case looks purely utilitarian. No always-on display in the traditional sense (MIP is always showing but low-res). Smart notifications are basic — read-only, no replies.

4. Xiaomi Watch S1 Active — Best Battery Life

If your top priority is "charge it and forget it," the Xiaomi Watch S1 Active delivers up to 12 days on a single charge. That's not a typo. It also packs a bright AMOLED display, built-in GPS, and over 100 workout modes — making it the endurance champion of budget smartwatches.

What stands out: 12-day battery life with typical use (7 days with heavy GPS use). The 1.43-inch AMOLED display is large, vibrant, and has an always-on mode. Over 100 workout modes cover everything from running to table tennis. The metal alloy frame and silicone band feel surprisingly premium for the price. 5ATM water resistance means you can swim with it.

The catch: The Mi Fitness app is functional but barebones compared to Samsung Health or Garmin Connect. Limited notification interaction — read and dismiss only. No NFC for payments in most regions. Software updates are infrequent and Xiaomi's track record for long-term support is mixed. The watch face selection is good but not as extensive as Amazfit's.

How to Choose the Right Budget Smartwatch

Know your phone ecosystem first. Samsung Galaxy Watch only works fully with Android. Apple Watch isn't in this price range. Amazfit, Garmin, and Xiaomi work with both iOS and Android (with varying feature support on iOS).

Battery life vs. features is the real trade-off. Watches with full app stores (Samsung) charge daily. Watches with long battery life (Amazfit, Xiaomi) sacrifice third-party apps. Decide which matters more before you buy.

Built-in GPS matters if you exercise without your phone. Connected GPS (using your phone's GPS) drains your phone battery and loses signal when you walk away from your phone. If you run, hike, or bike phone-free, built-in GPS is non-negotiable.

AMOLED vs. MIP display. AMOLED screens are vibrant and great for indoor use but can be hard to read in direct sunlight and consume more battery. MIP (Memory-in-Pixel) displays are always-on, always readable in sunlight, and sip battery — but they look low-res and dull indoors. Pick based on where you'll use it most.

Renewed vs. new. A renewed flagship (like the Galaxy Watch 4) gives you premium features at budget prices, but you're trading warranty security and battery health for those features. Check seller ratings and return policies before buying renewed.

What This Means For You

You don't need to drop $300+ for a capable smartwatch. The Amazfit Bip 5 gives you the best balance of features, battery, and display for under $100. Want real apps? A renewed Galaxy Watch 4 gets you Wear OS for budget money. Runners should go Garmin — the Forerunner 45's GPS accuracy and training features are unmatched at this price. And if battery anxiety is your thing, the Xiaomi Watch S1 Active will let you forget your charger exists.

The key takeaway: match the watch to your actual use case. A fitness-first runner doesn't need an app store, and someone who wants Spotify on their wrist won't be happy with a Garmin. Pick the tool built for the job, not the one with the longest spec sheet.
