Hi bear7926. Yes, that is what I ended up doing, and it seems to stay off now. I would have preferred to do it only once on my pull up menu on the bottom of the phone. Those selections are like shortcuts so you do not have to wander into settings for something like having WiFi or Aeroplane Mode, or Bluetooth turned off and on. I prefer it that way myself.
What I do not understand is why Apple would set up the OS to keep turning bluetooth on in the first place. Not everyone uses bluetooth devices. I for one do not use them, and I do not personally know anyone who uses them. I am not even sure what they are. Why presume all users need or want bluetooth turned on everyday? Even for those people who do use bluetooth, it does not necessarily follow that they will use bluetooth every day and thus drain their batteries faster because of it.
I do not like the changes in this new OS. It has made for more work, more confusion, and more frustration for me. I also notice that my battery runs down a lot faster now, which is never a plus.
I can only speak for myself, but personally, I am worried about Apple. For example, Apple's once superior tech support seems to be going the way of Windows/Microsoft tech support. Microsoft used to have great tech support, too, until they changed it.
I recall phoning Microsoft tech support about a problem occasionally and very seldom ever having to speak to more than the first person who answered the call. Then, as time passed, they implemented a terrible tier of support, and you could not get around it. At that point, every time I phoned for help with something, I had to go through the entire thing with one person who usually could not help me, and then they would transfer me to a level two tech, and I would go through it all again, and usually the level two tech was of no help either, and I would have to be transferred again. I often ended up speaking to 5 or more different techs and phoning back about the same problem over and over again. It was exhausting and frustrating in the extreme, and it was one of the main reasons why I switched to Mac. I was sick and tired of their "service paks" and poor support that ate up enormous amounts of my time. I was sick of Microsoft blaming the computer maker for the problem, and the computer maker blaming Microsoft, and eventually both of them blaming my innocent ISP! I felt like a ping pong ball being batted around from one to the other all of the time.
With Mac, I had far, far fewer problems that required me to contact tech support, but if I did have to contact tech support, I was usually put out of my misery so to speak by the first tech to whom I spoke, and it was usually done within a very few minutes---none of that being on the phone literally for hours sometimes as had done with Microsoft tech support. Now, Apple seems to be going in the same direction with tech support. I have to ask myself, why?
I am speculating here, but my guess is the reason is money. (Is it not always?) They hire fewer highly trained and experienced techs and more less experienced techs to try to handle technical problems for a lower cost. In other words, using random numbers here, why pay 50 top techs $25 an hour if they can pay less experienced techs who "hopefully" can solve customer tech problems at only $15 an hour? I do not like it. What used to make Apple great and completely distinguish it from Microsoft, such as its tech support, seems to be changing and not for the better.
Anyway, these are my thoughts on the newest OS and tech support. Please feel free to disagree if you disagree. I do not claim to be infallible, but this is how it looks to me.
