Unless i misunderstood and not trying to be rude, but you guys really have to use stuff more often before saying something is a problem, if you lock the screen on a windows device with the lock button and HERE maps is navigating the voice keeps going and it turns the screen off, nokia been doing this for years, its not something only iphone does. You can unlock it and resume where you left off and that way you save battery with the screen off you can also run other apps at the sametime and the voice keeps going. I'm not saying HERE interface is better than google just saying they are more accurate. And for the guy saying i'm argueing i'm literally telling you that i use both GOOGLE and hERE every single day and drive all day and HERE is more accurate what more testing do you need. I'm not a ****** i just use what works. Nokia sells there product for profit google does not, nokia has more incentive to make better maps. Some of the limitations to HERE maps is due to windows at the moment. If anybody here ever use nokia maps back in the day some of them were the best interface around and most accurate they havent caught up int he windows platform they only been working on it a few years where the symbian one was refined over 10 years. But ya just lock the screen? unless thats not what your talkin about.
Oh and PS mine does charge while using HERE i cant speak for WAZE, you might just need a bigger charger, actually it charges almost at normal speed with GPS on, HERE is really a battery sucker for me. But i havent used WAZE i dont use alot of the extra stuff i just need to get to where i'm going, since they both use the same maps i just use nokia cause its lighter.
