I think the main problem here is hardware/software of Nokia. I think WP8 OS is solid. There may be a few apps with programming issues causing random drains but my Surface works fine. I get advertised use out of battery more or less and no random drains or weird battery reporting. It's built off same software more or less, right? I don't see near as many complaints with HTC, but that may not be true. It doesn't appear as many were sold. From what I've seen from my experience and other posts, it would appear to be a Nokia problem. MS and Nokia know where the problem lies and we will never know. All I can know for sure is that this will be my last Nokia product. I don't care at this point where or what the problem is. It has to be a battery monitoring or reporting issue in Nokia software or just bad hardware. They are new to smartphones, I get it. They will get it figured out. I've always bought name brand, flagship phones because they are supposed to be the best. Nokia was THE phone manufacture back in their day, but they have a few bugs to work out to get back to that position. I just feel foolish for listening to the hype and not waiting for proof of delivery.
