The Amazfit Bip 6 is a strong affordable pick if long advertised battery life is your priority, but it is not a proven universal winner. Amazfit’s US listing, accessed in 2026, priced it at $79.99 and claimed up to 14 days of battery life, or up to 6 days with heavy use. Huawei’s WATCH FIT 4 is a relevant alternative with a manufacturer claim of up to 10 days. Those figures come from different conditions, so they do not establish which watch lasts longer in a fair head-to-head test.
Which affordable smartwatch should you choose?
For a low-cost, watch-shaped wearable with a notably high battery-life claim, start with the Amazfit Bip 6. Its US product listing showed a price of $79.99 and advertised up to 14 days of battery life; it also listed up to 6 days for heavy use. These are Amazfit estimates, not guaranteed results for every owner.

The Huawei WATCH FIT 4 is another model to consider. Huawei advertises up to 10 days on its Singapore product page, while its UK page explains a typical-use scenario. Since the manufacturers do not provide matching test conditions here, the figures are not a direct comparison. No comparable independent test across these affordable models establishes a real-world battery-life winner.

How the advertised battery figures compare
| Model | Advertised battery life | Price information | What the figure means |
|---|---|---|---|
| Amazfit Bip 6 | Up to 14 days; up to 6 days in heavy use | $79.99 on Amazfit’s US listing, accessed in 2026 | Manufacturer estimates. The listing does not make these guarantees of everyday ownership. |
| HUAWEI WATCH FIT 4 | Up to 10 days | Not stated in the cited Singapore product page | Manufacturer claim. Huawei UK describes a typical-use scenario, but it is not the same test basis as the Bip 6 listing. |
Battery specifications are most useful as a starting point, not as a promise. Huawei’s UK typical-use scenario includes always-on heart-rate monitoring, sleep tracking, notifications, exercise, and limited screen-on time per day. The cited Bip 6 listing gives a separate heavy-use estimate. Neither establishes what the other watch would achieve under the same settings and activity.

What changes how long a smartwatch lasts?
Features that keep the screen, sensors, or wireless connections active can make a headline maximum a poor forecast for your routine. Consider your usual settings and how often you use:
- Always-on display and frequent screen checks
- GPS-enabled workouts
- Calls and music
- Notifications
- Health monitoring, including heart-rate tracking
The available product information does not quantify the exact battery-life impact of each feature across both watches. For a useful estimate, look for a model’s figure under settings closest to your own use, and distinguish standard, heavy-use, and GPS workout claims rather than treating them as interchangeable.

How to decide which watch is the better buy
- Set a price ceiling in your market. The Bip 6’s $79.99 figure is from a US listing accessed in 2026, not a universal current street price. Compare local checkout prices, and check warranty and support availability where you live.
- Match the battery estimate to your routine. Give more weight to a heavy-use or GPS figure if you exercise often or keep features active; a maximum-use claim may not reflect your settings.
- Check phone compatibility and smart features. Huawei’s UK page lists Android 8.0 or later and iOS 13.0 or later paired with Huawei Health. Confirm compatibility and feature availability in your region before buying; regional services and features should not be assumed to transfer unchanged.
- Choose by health and workout priorities. The Bip 6 listing specifies 140+ workout modes, an AMOLED display, and BioTracker health tracking. Compare the features you will actually use rather than choosing by the battery number alone.
- Decide whether you want a watch or a band. Budget roundups sometimes group band-shaped fitness trackers with smartwatches. A band may suit a fitness-first buyer, but it may not provide the watch experience or smart features they expect.
Other budget wearables worth checking
Amazfit Active 2 and Xiaomi Smart Band 10 also appear in 2026 coverage as lower-cost, fitness-oriented alternatives. TechRadar reports testing for its roundup, but the available information does not provide a comparable battery methodology that would support ranking either against the Bip 6. A band such as the Xiaomi Smart Band 10 also differs in form factor from a watch-shaped smartwatch.

Editorial picks reflect different criteria: Android Central’s July 2026 roundup names the Bip 6 as its best budget battery-life pick, while Tom’s Guide’s 2026 cheap-smartwatch guide selects the Amazfit Active 2 as its best cheap smartwatch. Those recommendations offer context, not a controlled battery comparison with the WATCH FIT 4.
