I know what the real problem is with the battery drain, and I hope this post gets sticked, there are actually 2 problems: 1. These phones (including my brand new Nokia Lumia 1020) are made in China; and 2. Windows Mobile is made by Microsoft. I'm sorry if my post offends some but before you start blabing about it read my next sentence.
In 2008, think it was in the autumn I buyed my first smartphone (Nokia N95 8GB). 1. Made in Finland; 2. It had Symbian (made by Nokia I belive). I swear that I never had any problems with my software on that phone (my last update was in 2011 when I update to Symbian Ana [last symbian made]. I dropped that N95 on the floor so many times the battery cover bearly holds anymore, I used that phone as anything possible it could ever be (that includes being a modem for a network with 3 laptops via a 3g internet connection. It rained on that phone, I burned it 1 time accidently, It snowed on it, sometimes it was so cold I could bearly hold it in my hands, anyhing possible has happened to it but IT NEVER F****ED UP LIKE NOKIA+WM8 DOES. And you know why? Because it wasn't made with cheap chinesse matherials and it wasnt softare implemented by Microsoft, a company who still cant manage a normal pc windows os, even after 1000000000000 years of experience.
So there you go. There is no problem with installed apps, 2-3-4-100000000000g connection, syncing or 3x cycle or who knows what other issue. THE ONLY PROBLEM WITH THESE PHONES BATTERY DRAINAGE IS THE DEADLY COMBINATION NOKIA HAS BECOME (MS + CHINA) AND THERE WILL ONLY BE SOLVED IF NOKIA DEVELOPS ITS OWN PHONES IN FINLAND AND THEY DO THEIR OWN OPERATING SYSTEM.
But that will not be happening soon since Nokia = Microsoft and viceversa. Good night everyone.
PS - Nokia Lumia 1020 users buy some Camera Grips they give extra juice...
