One thing i've learned over the years is that what is complained about on forums is a small minority of users. . . and they are very vocal. Common Wisdom is never to be trusted.
The fact is that Apple uses standard Bluetooth radios and hardware supplied from standard suppliers such as CISCO and Qualcom. If there is a problem connecting, the problem is in the hardware and it should be there for everyone. Usually it is a problem with a batch of the chips provided on a small number of the iPhones/iPads and can be hard to track down. Sometimes it can be handled in software with changes in firmware, sometimes it takes a swap out of the device.
That said, Apple is not above making mistakes in their software. . . and sometimes the fixes they put in to address the issues with the problem chips create problems for chipsets that were working fine before. That happened with the iOS 8.1.3 release for a small number of users. . . who also cried out very vocally. When a company such as Apple is churning out 15 million iPhone 6 and 6 plus models, they have to accept various suppliers offerings of chipsets. . . and they try their best to make sure that everything works together. Sometimes, I think, the suppliers, to meet demand, drop in some sub-par chipsets, or even some from another model, that meets specs, but do not quite work exactly the same as the ones specified. Should these be caught before being installed? You bet your bippy. But that's a perfect world.
I just know that when I read these real world problems that a very small minority of Apple users report, but know that I have the EXACT same model they have and am not experiencing what they are describing. . . nor are any of my friends. . . nor are any of the other millions of users with that model. Errors of this type usually affect far less than 1% of the models involved.
The anti-Apple trolls pick up on these forum complaints and cry these are "endemic" and "exemplary" in the Apple device and normal for Apple products, when they are not.
