A bit hard to understand you but no iOS does not disconnect all the devices when you lock the phone. I often use hotspot because the internet at work is shit. My phone does not have to be unlock all day, that would be stupid.

I think iOS does disconnect the device if there is no network activity after a certain time but I am not very sure about this. Correct me if I am wrong.

The double tap sounds like a last min attempt by Apple to add a new feature by just slightly modifying the accessibility feature.

I was aiming for a stainless steel Apple Watch for its cellular and sapphire glass so the Ultra isn’t that far off. I expected the Ultra to be much higher in price because this is Apple but was surprised that it is barely more expensive than the stainless steel ones.

As a runner, the dual band GPS does make the turns more sharp and accurate as compared to my SS Series 5. Also the battery life allows me to attend running activities with my running clubs right after work as compared to my SS Series 5 which is usually like 30-40% battery life by 6pm.

Yeap. Some can even do a 48 hours one.

Not a medical expert but I guess you are looking into PVCs is it? If so, the cardiologist will do a 24 hour ECG and tell you in the 24 hours, how many percentage of your heart beat is normal and how many aren’t. Then with the percentage tell if you need further treatment or not.

It is accurate as long as the signal quality is good. I don’t think there would be so much coincident that would make you get a misdiagnosis and chances the cardiologist will just do a ECG or 24 hour holter just to be sure.
