The 5 Best Smartwatches for OnePlus Smartphones in 2021

OnePlus has grown crazy fast in a short period of time and it is for sure still going strong. Now, I have seen several questions being asked on the web about what smartwatches would be compatible with the newer OnePlus 6 or even older models. 

To help you out I’ve created a list of 5 smartwatches that will work well together with all different kinds of OnePlus smartphones!

Our Top Picks

1. Samsung Galaxy Watch

Samsung Galaxy Watch (42mm, GPS, Bluetooth) – Midnight Black (US Version)

The Samsung Galaxy Watch is a fantastic gadget for your Oneplus device. Even though it’s supposed to be used with Samsung products only, the watch will work very well with an Oneplus smartphone too. It has 1.5GB of RAM and 4 GB of internal storage space, which can hold all kinds of apps from both third-party developers as well as those created by Samsung themselves.

The Gear S3 has many impressive features. For example, it can track your sleep as well as workout times and heart rate level throughout the day. It also has Bluetooth capabilities for connecting to devices such as smartphones or laptops so you never miss an important event.

The inbuilt GPS system combined with LTE allows you to use map apps on your watch without ever having to take out your phone again-a major convenience when traveling abroad while sightseeing is what many do nowadays.

You will have about 1-4 days before needing another charge depending on how often you wear it during the day. However, if you were wearing one every day then charging may be more frequent than just once per week because battery life varies according to usage habits.

Final thoughts

All kinds of smartwatches have been discussed on this list, from budget ones to premium one. All the watches that we’ve talked about come with in-built GPS and HR Sensors so they’re a fantastic investment no matter what you can afford. You’ll get more accurate readings if you pay for an expensive option but less reliable data is still better than not having any at all if your budget isn’t as tight.


What size display should I look for in a smartwatch?

The display of a smartwatch is very important because it’s the one you will be looking at every day. So, if your watch has a small screen then this can cause eye strain in the long run.

The ideal size for a smartwatch would be 1.3-inches on minimum but that number varies per person so to find out what size works best for yourself head over to Samsung or any other brand store and check out all their available options before making up your mind.

How accurate are the heart rate readings on a smartwatch?

These sensors are not 100% accurate, but they can still predict your heart rate. You’ll only be off by a beat or two depending on which model you choose.

Can I swim if my smartwatch is waterproof?

Most smartwatches these days have a waterproof design that allows it to withstand dips into pools or baths without any problems. Some brands offer better accuracy for swimming than others so make sure to consider which one suits you best!

Can you use Apple Watch with OnePlus?

Apple watches are not designed to be used with anything that is not an Apple device. You will never be able to set up your smartwatch without an iPhone, so my advice would be to stay away from them.

Is the Samsung smartwatch compatible with OnePlus?

The Samsung watch is compatible with Oneplus, which means you can sign in to your phone using it. But the messaging app in Oneplus will not work when receiving notifications from messages on the Samsung watch messages.

Does OnePlus have a smartwatch?

The company’s latest flagship handsets, the OnePlus 9 and OnePlus 9 Pro debuted alongside their first smartwatch. The watch is loaded with features we’ve come to expect on the best smartwatches, including fitness tracking and blood oxygen monitoring- not to mention a weeklong battery life!
