Hopefully!
I'm currently running 8. 3 Beta 1'and it still drops out let's say twice an hour or so, but great improvement on before.
8.2 when released in next month will we hope eliminate the issue even though 8.3 still has the problem.
It is widely said that ios9 which is currently being developed will have hardly any new features but will be solely developed to rid the system of bugs and improve the iOS software. Let's hope so
