How we rank these for you

At this price, you're buying long battery life and numbers you can roughly trust, so those two count most. Everyday features and the screen come next. Our order also weighs how many buyers each watch suits and how sure we are of it. That's why the Redmi Watch 5 Active sits second despite the lowest score: it's plain, but it's a safe choice if you mostly want alerts and rare charging. The Haylou Watch 4S scores higher yet sits last, because it isn't built for swimming and less is known about it.

We rate each pick on these needs, weighted as follows, and list the picks by score, highest first. The top pick in a guide shows 10.0, and the others show how far behind it they are, down to 7.0. So a score compares picks within this guide only, and it's our opinion of the evidence, not a lab result.

Tracking accuracy30% of the score

Cheap watches list the same sensors as costly ones, but the numbers aren't equally trustworthy, so this scores how far you can rely on steps, sleep and routes.

Real battery life30% of the score

Long battery life is the main reason to buy a cheap watch, and real results often land well short of the maker's claim.

Everyday features25% of the score

Bluetooth calls, built-in GPS and message replies are what usually get dropped to hit a low cost, and you'll notice each one in a normal week.

Screen quality15% of the score

AMOLED and LCD panels both appear here, and you'll see the difference outdoors and in sharpness every time you check the time.

Best All-Rounder With AMOLED and GPS

1. Xiaomi Redmi Watch 5 Lite

Tested Hands-On by

Best for: You want one cheap watch that does most things well: a big, bright screen, GPS for walks and runs, and sleep tracking.

Skip it if: An exact daily step count is the point of buying a watch, or you want to reply to messages from your wrist.

This is the one we'd buy. It has a big AMOLED screen you can read in direct sun, built-in GPS and enough battery to forget the charger for a week. Say you walk the dog before work and check your stats at lunch: the route is logged, and the screen stays clear outdoors. Plan on about 7 days with the always-on display and full monitoring, or about 12 with them off, per AndroidGuys. Ignore the 18-day claim. Buyers on PcComponentes keep praising the battery and screen, though a couple complain about route recording, which is worth knowing if you ride or hike long routes. The real weakness is counting: steps and calories can be wrong, so treat them as rough. You also can't reply to messages. Xiaomi has since released the Redmi Watch 6 Lite, so this isn't the newest model.

Reviews behind this pick

  • AndroidGuys: A strong budget option with a good screen, GPS and sleep tracking, marked down for step counts and missing replies.
  • WalasTech (4.3): A well-balanced watch for casual and fitness-minded users, though the page reports no test data.

Pros

  • About 7 days with the always-on display
  • Readable in direct sunlight
  • 5ATM rating and 29.2g case

Cons

  • Unreliable step and calorie counts
  • No automatic brightness
  • No texting from the watch

Best for Casual Dry-Land Runners

2. Haylou Watch 4S

Tested Hands-On by

Best for: You run or walk outdoors, want a round AMOLED screen and built-in GPS, and will keep the watch out of the pool.

Skip it if: You swim, want detailed health statistics or need alerts you can feel while you're moving.

Pick this only if you run or walk outdoors and want a round AMOLED screen with GPS. It has the strongest single accuracy result here: on one run, iXBT Live logged 17.33 km against 17.02 km on an Amazfit Cheetah Pro. That's one run in a blog post with an advertising disclosure, so we treat it as promising, not proven, and that's why this watch sits last. Battery looks good, with 9 days of mixed use that included GPS and treadmill workouts. Ignore heart rate for the first 5 to 10 minutes of a workout, when it can read about 20 bpm high. Say you're out in a winter coat: the weak vibration makes it easy to miss an alert, and messages cut off at around 90 characters anyway. Its 1ATM rating covers rain and sweat, not swimming, so skip it if you swim.

Reviews behind this pick

  • iXBT Live: A budget watch with a good display, reasonable sports accuracy and useful calling, held back by simplified statistics.
  • Digital Trends Español: A simple, unpretentious watch with strong value and battery, limited by basic notifications and no swim suitability.

Pros

  • Under 2% distance gap against an Amazfit Cheetah Pro in one run
  • Readable in direct sunlight at full brightness
  • Loud call speaker

Cons

  • 1ATM rating, so no swimming
  • Heart rate spikes early in workouts
  • Simple app and basic notifications

Best Design

3. CMF Watch Pro 2

Best for: You care how a watch looks and want a good-looking round one for notifications, calls and light activity.

Skip it if: You run or ride with GPS and don't want to wait for a signal, or you care about sleep stages and workout heart rate.

Buy this for how it looks and feels, not for GPS. The round AMOLED screen, working rotating crown and swappable bezels make it the most fun watch here, and it suits calls, alerts and light activity. The problem is outdoor tracking. GSMArena saw 2 to 5 minute locks but logs that nearly matched Samsung, Garmin and Coros devices, so the data can be fine once it starts. We still side with the doubters, because owners on the Nothing Community forum keep reporting long waits or no lock at all, with no confirmed fix, though not everyone hits it. Say you step out for a run before work: you could spend those minutes standing in the street. Battery's solid, at about 4 to 6 days with the always-on display and close to 10 without. Skip it if you want dependable GPS or sleep stages. CMF has since released the Watch 3 Pro.

Reviews behind this pick

  • Android Authority: A fun, decent basic smartwatch whose health and fitness tracking is not good enough for dedicated activity use.
  • GSMArena: Hard to beat for its cost thanks to its design and clean software, despite laggy GPS and few advanced health features.

Pros

  • Swappable bezels and a rotating crown
  • Bright AMOLED screen
  • Clean software

Cons

  • Slow, unreliable GPS lock
  • Sleep stages barely match reference devices
  • No app store, and auto-brightness can run dim

Best for Basics and Rare Charging

4. Xiaomi Redmi Watch 5 Active

Best for: You mainly want notifications, calls, sleep data and a large screen, and you'd rather charge as rarely as possible.

Skip it if: You swim, want routes without carrying your phone, or want the time showing on an always-on display.

Buy this if you hate charging and mostly want calls, alerts and sleep data. Expect about a week per charge even with workouts and calls on. With lighter use it goes much further: The Week still had 55% left after 12 days at about 40% brightness. Say you leave your charger at home for a long weekend: you won't think about it. Don't trust the step count, though. Some accounts call it accurate, but Outlook Business saw 20% to 30% fewer steps than a OnePlus Watch 2R, and that side-by-side comparison is the evidence we believe. Use it to compare one day with another, not as an exact total. There's no built-in GPS, always-on display, message replies or swim mode. The chunky, uneven bezel only matters if looks matter to you. Xiaomi has since launched the Redmi Watch 6 Active.

Reviews behind this pick

  • The Week: A good addition to Redmi's range if you accept its size and can skip apps, replies and an always-on screen.
  • Outlook Business: Likely the best watch in its low-cost Indian class, with battery as its strength and step and GPS accuracy as its limits.
  • Business Today: A solid everyday budget watch, though not the most accurate fitness tracker and flawed in its bezel design.

Pros

  • About a week or more per charge
  • Sleep totals within 0.1 to 0.2 hours of a OnePlus Watch 2R in one comparison
  • Screen readable in direct sunlight

Cons

  • Thick, uneven bezels
  • No always-on display, message replies or swim mode
  • Heart rate and SpO2 less reliable than pricier watches

Buying guide

Don't expect the newest model

Three of these four watches already have a newer version on sale, and that's normal at this level. Buy for what the watch does today, and be wary of unknown brands with big spec lists and no independent review, because you've got no way to know whether the numbers mean anything.

Decide if you really need GPS

All four picks handle Bluetooth calls, so GPS is the bigger choice. If you walk or run outdoors and want your route, the Redmi Watch 5 Lite is our first stop. If you only want steps and alerts, the Redmi Watch 5 Active is fine without it. Having GPS isn't enough on its own: on the CMF Watch Pro 2, expect to wait for a lock.

Treat step counts as a trend

Use these numbers to compare your own days, not as exact totals. A step count that's off by the same amount every day can still tell you whether this week was more active than last. Don't change your training or your health decisions because of one reading from a cheap watch.

Buy for habits, not precise training

These watches are good at nudging you to move and showing how you slept over time. If you train by pace or heart rate zones, spend more on a proper sports watch, because that's where cheap sensors let you down, especially at the start of a workout.

Frequently asked questions

What is the best cheap smartwatch here?

We'd buy the Redmi Watch 5 Lite. Its bright AMOLED screen, built-in GPS and week or more of battery cover the most ground, as long as you treat its step count as a rough guide.

Which of these watches have built-in GPS?

The Redmi Watch 5 Lite, CMF Watch Pro 2 and Haylou Watch 4S have it, though the CMF can be slow to lock. The Redmi Watch 5 Active doesn't, so skip it if you want to track routes.

Which cheap smartwatch lasts longest on a charge?

Choose the Redmi Watch 5 Active if battery is all you care about, since light use can stretch well past 12 days. The Redmi Watch 5 Lite is close behind at about 12 days with the always-on display off. Your settings will change this.

Can I swim with any of these watches?

The Redmi Watch 5 Lite is your best bet, with a 5ATM rating. Skip the Redmi Watch 5 Active, which has no swim mode, and the Haylou Watch 4S, whose 1ATM rating only covers rain and sweat. Check CMF's own listing before swimming with the Watch Pro 2.
