I've just got back from a long weekend away with my family and am looking forward to putting my 950 through is paces in my general day to day use. I saw a comment questioning the signal quality, as I only got my new (but 2nd) 950 on Thursday then went away on Friday to a mobile signal unfriendly area, I can't comment, but I will be keeping an eye on it over the coming week.
I've not seen any issues with the battery life, but coming from the iPhone which's battery isn't all that great so it's no a great comparison. I have to admit, that I am in the situation that I have two batteries for the Lumia 950, as I still have the cracked screen handset which still works all be it that I can not see anything on the screen
, so I have a spare battery that I could keep charged. Also, because of the iPhones battery life, I've always carried around a portable battery pack in my bag.
The app issue people mention isn't really an issue, unless more drop of the radar and specifically the ones I use. I am not an app heavy user, I never had that many on my iPhones or Android handsets, and the core apps have a version on Windows, and the missing two I have found practical and minor work arounds.
As for the likes of Amazon or eBay etc, I never used them on my phone, and to be honest I actually think they are bad as it promotes easy access to buying crap you don't need.
My concern will be if any more that I use fall to their death.
