Can I trust the heart rate monitor found on cheap smartwatches?
Hi Ronaldo! I am thinking of buying one of these smartwatches from China, to monitor my heart rate, blood pressure and sleep quality. There are dozens of models offered for a very low value compared to Apple's smartwatch. But can I trust the data presented by these generic monitors? Ana Paula

Hello Ana Paula! The accuracy of sensors that monitor vital data depends on a technology that has not yet been able to significantly reduce cost.
Maybe that's one of the reasons that make most reliable devices so expensive. For example the Apple Watch Series 4 has sensors capable of making a user's electrocardiogram (ECG); He will also be able to warn the user if he possibly has a serious heart condition called atrial fibrillation.
These features have been approved by the American Heart Association, and have been released by the US FDA as a new type of medical device.
Apple's device is not the first piece of wearable technology to have ECG capability. You need to check if the smartwatch you intend to buy has this approval.
But it is noteworthy that the reading presented by the sensors requires some care indicated by the manufacturer not to compromise the accuracy. And most importantly, this type of device does not replace physician follow-up.
IPhone battery after installing iOS 13

Hello Ricardo! Many users have complained on the internet about this unexpected behavior.
Since the operating system has been distributed to more than one iPhone model, this issue may not have reached all iOS 13 supported devices.
Bug fixes reported by users are now available. I recommend you download and install iOS 13.1.1 to resolve this issue.
