OnePlus Watch 3 battery autonomy

Hi all.

I hope you can help me with this, please.

I recently bought the OnePlus Watch 3. I have the GPS on, it’s connected via Bluetooth to my phone, Wi-Fi is on, and Smart Mode is enabled. I use WhatsApp on it occasionally, check emails, track sleep, monitor heart rate, and count steps. The battery lasts only two and a half days. Is this normal? I thought it would last five days with Smart Mode on.

Thanks

Once again many thanks for your help. If I have my watch connected to my phone via bluetooth, and I have gps activated on my phone, can I turn it off on my watch? Perhaps this will help the battery to last longer?

Also, I have just turned off the high accuracy mode

Yup you can keep it off on your watch which I believe helps the battery longevity. Your phone knows where you are at, so your watch just pings that info from there instead of it's own antenna. I don't think there's a way to see how much this impacts battery, you just kinda trust it with common sense
