yes and NO, when ever I get pissed that I only get 3 hrs out the phone I start cursing and go back to my HTC ONE, it only takes couple of hrs to realize that WP is better(and charge the phone and switch back) and I should stick it out until MS or Nokia fixes the issue. I believe the issue is with the kernel or something very intricate with in the OS, which is why they are waiting till 8.1 to fix it, I just cant find any other reason as to why they are waiting too long to fix this battery draining problem. Nokia or MS haven't commented on this(that I know of) which is why I was hoping it would quietly be fixed with GDR2 but it wasn't, which then lead me to the above statement.
suck it up and wait till 8.1 it should only be another 6 months or so
