COLMI P81 smartwatch overview

The COLMI P81 Bluetooth Calling Smart Watch is listed in our Smart Watches category in black. According to the listing, its 1.9-inch full-touch TFT display has a resolution of 240×284 pixels. The body is listed as ABS+PC and the strap as silicone, with a strap width of 20mm. Taken together, these details describe the watch’s build and screen as the maker presents them. The listing does not say how the strap feels after long hours, so that question is left open here.

Inside the COLMI P81, the listing names a JieLi JL7012F6 processor with 640KB RAM and 64MB ROM. It is listed with Bluetooth 5.3 connectivity and an IP68 waterproof rating. The maker also lists a heart rate sensor and an SpO2 monitor. These are the main points we can confirm from the source, and the rest of this page avoids going beyond them.

This page separates what the listing states from what it does not. Where the source is silent, we say so rather than fill the gap. For the maker’s own product details, visit the maker’s website. If you are choosing a COLMI P81 for the first time, read the features and specifications first, then check the compatibility notes against the phone you plan to use in Dhaka, Chittagong or elsewhere in Bangladesh. Reading in that order helps you decide with the facts in front of you.

Key features

Full-touch 1.9-inch TFT display

The COLMI P81 uses a 1.9-inch full-touch TFT screen with a resolution of 240×284 pixels, as listed by the maker. The listing describes the touch type as full-screen touch. For many buyers in Bangladesh, that matters on a Dhaka commute, when you want to glance at the screen quickly without digging for a phone. The listing does not state screen brightness, so this page does not quote a figure. If you want to see the screen before you order, ask our team by phone or on Facebook Messenger.

JieLi JL7012F6 processor and memory

The listing names the JieLi JL7012F6 as the processor in the COLMI P81, paired with 640KB RAM and 64MB ROM. Those are the memory figures the maker lists, and they are the only memory details this page uses. The listing does not describe how many tasks run at once or how the watch performs in daily use, so we leave those points open. When you read the specification table, focus on the features you will use most, such as calling, the heart rate reading and the screen. That way you can judge the COLMI P81 against your own needs rather than against a single number.

Bluetooth 5.3 connectivity and calling

The product name describes the COLMI P81 as a Bluetooth calling smart watch, and the listing gives Bluetooth 5.3 as its connectivity version. Calling from the wrist depends on the watch and your phone working together over Bluetooth, so check that your phone is on the compatibility list first. The listing does not describe call quality, call range or how many devices can be paired, so this page makes no claims about them. Keep the watch near your phone while you pair it, and make your first test calls at home, where you can see whether the connection holds for you.

Heart rate sensor and SpO2 monitor

The listing says the COLMI P81 has a heart rate sensor and an SpO2 monitor, and it names the heart rate chip as LC09. The maker describes these features as part of comprehensive health monitoring, but the listing does not give accuracy figures or any clinical use. Treat each reading as general information rather than a medical result, and speak to a doctor about any health concern. For many buyers in Bangladesh, the appeal is simply having a wrist-based reading to look at over several days. Keep the watch clean and dry between uses, and follow the maker’s instructions for wearing it.

Battery, charging and daily use

The COLMI P81 houses a 300mAh lithium-polymer battery, which the listing says delivers 3 to 5 days of usage. The maker lists charging with a 2-pin magnetic cable, taking approximately 2 hours. The listing also names a Seiko Y1 protection IC, and we pass that detail on without explaining its role. For Bangladeshi households, a battery that lasts several days can be useful during load-shedding, when you may not know when mains power returns. The watch still needs charging before then, so keep the cable within easy reach at home.

Strap, body and fit

The body of the COLMI P81 is listed as ABS+PC, and the strap as silicone with a width of 20mm. The watch body is listed at 44.5 x 36.4 x 10.4mm. Whether that suits your wrist depends on your own measurement, and the listing does not give a wrist size range, so measure before you order. Silicone is a common strap material for daily wear, but the listing does not describe comfort over long hours. Check the 20mm strap width before you decide, and consider how the watch will sit on your wrist during a long working day.

Specifications

The table below lists the COLMI P81 specifications as the product listing gives them.

These are listed specifications from the product listing for the COLMI P81, and the table reproduces them without change.

How to use / set up

Setup for the COLMI P81 should follow the maker’s instructions, which the listing does not reproduce in full. Charge the COLMI P81 fully before first use. Use the 2-pin magnetic cable named in the listing, and keep the charging area dry. Once the watch has charged, you can move on to pairing with your phone.

Next, install the app named in the listing, Da Fit, on a compatible phone. Check that your phone runs Android 4.4 and above, iOS 8.0 and above, or HarmonyOS, as the listing states. When the app is ready, follow the maker’s instructions to pair the COLMI P81 with your phone. Keep the phone and watch close together during pairing, and keep the phone’s Bluetooth switched on.

If you need the watch in another language, check the list first. The listing gives watch languages as English, Chinese, German, French, Spanish, Arabic, Russian, Ukrainian, Italian and Portuguese, and it gives a longer list for the app. Choose your preferred language before you start daily use.

Daily care is simple. A quick wipe after exercise or a humid commute keeps the strap and body clean, and drying the strap after sweat helps it stay in good condition. Keep the watch away from very hot surfaces, and avoid charging it while it is wet. Store it somewhere dry when you are not wearing it, which is a sensible habit during Bangladesh’s humid months.

Keep the charging cable in a fixed place at home, so that the watch can be topped up before a planned power cut. If you travel between Dhaka and another district, pack the cable with the watch so that you do not depend on finding a matching cable on the road. Good habits like these help any wearable last longer.

If the COLMI P81 does not pair, check that your phone is on the compatibility list, that Bluetooth is on, and that the watch has charge. Then contact us using the details in the delivery and ordering section below. We would rather help you sort out a setup question than leave you guessing about a new COLMI P81.

Compatibility and what is in the box

According to the listing, the COLMI P81 is compatible with Android 4.4 and above, iOS 8.0 and above, and HarmonyOS. It is listed with the Da Fit app. The listing does not name other platforms or apps, so this page does not claim support for them. If your phone is on an older system, check the listed versions first.

Phone systems change over time, so if you use an older handset or a tablet, check that its system version matches the list above. The listing names operating systems rather than individual phone models, so ask us if the match is unclear for your COLMI P81.

The listing does not confirm the contents of the box. Whether a charger or any other accessory is included is not confirmed by the listing, so ask us if that matters to you. Please check the delivered item against your order when it arrives.

Message us if you have any doubt about your phone’s system version or about which model suits your wrist. A short question can save a return later, and we can point you to the right details in the listing.

Who should buy it in Bangladesh

The COLMI P81 suits buyers who want a Bluetooth calling watch with a full-touch display and listed heart rate and SpO2 sensors. It is a practical choice for people who want a screen on the wrist during the day rather than reaching for a phone each time.

A commuter in Dhaka who wants to check the screen and take calls without reaching for a phone on a bus or rickshaw may find this useful, as long as the phone pairs well with the watch. Test the pairing at home first, not during the journey.

A person who wants a wrist-based heart rate reading to look at over several days may find the COLMI P81 a good match for that purpose. Remember that the listing presents these readings as part of health monitoring, and that a reading is not a medical result.

Someone who wants a watch mainly for a child should look at our kids smart watch range instead, because the listing for the COLMI P81 does not describe that use.

A gift buyer should look at the phone platform of the person receiving the watch first, because the listing names specific Android, iOS and HarmonyOS versions for the COLMI P81. Ask us if you are unsure which version applies.

Office workers who spend much of the day at a desk may prefer to glance at a screen on the wrist rather than reaching for a phone. Households that share one phone should decide which phone the watch will pair with before ordering.

A buyer who already uses earphones for calls may still want a watch for quick checks. Think about whether a wrist screen adds something to your routine before you choose.

Someone who wants to track fitness may find the listed heart rate sensor useful, but the listing does not describe workout modes or step counting, so ask us before you decide.
