I have had my 950XL since late November, and I am loving it...best phone I have ever had. I had random reboots with 107, but not that I am on redstone and the latest firmware, I have not had a reboot that I am aware of. I have had some instances of overheating over the months, but I have solved them. One time I saw the messaging app was using a lot of the battery, and even rebooting it did not help. I ended up disabling it being able to run in the background, and the phone cooled down. Later I turned it back on and all was well. I think overheating and battery issues, at least for me, have been apps or processes running out of control in the background. I normally still have 40% left on my battery at the end of very long days. Now I do not play games, and am not the heaviest user, but I use it regularly. I also stop all programs from running when I am done with them most of the time, something I learned from my earliest windows phones. The only real issue I have is that the screen is not perfectly flat in the corners so I have problems with glass screen protectors, but I am living with that since the phone is working so well.
"The best phone I have ever had" and then the litany of problems. What kind of phones did you have earlier? My goodness, trust me - there are phones that actually work...
I am very disappointed with my Lumia 950XL. Incredibly unstable, every next build makes it even less stable, hard resets seem to make it even worse. I'm so tired of this. I can't do my work with this phone. The battery is terrible. I'm back to carrying battery packs to survive my work day. It's crazy and pathetic, considering that I paid as much as I would for an iPhone or premium android. As we speak I'm doing the second hard reset this weekend and going back to the official build. Redstone definitely didn't work for me. I started installing preview builds because the official ones didn't work. Even if official build will turn out to be stable and working it doesn't support visual voice mail, a feature that I've been using for a couple of years now and need for my work.
If you need a phone for work, a phone that you actually frequently use for many things, not just texting some chick then don't get this phone. Or maybe I should say don't get Windows 10 Mobile because that is the root of the problems.
The biggest issues I have with my 950 XL:
- constant reboots,
- frequently loses connectivity to internet, requires reboot,
- hot spot is the worst implementation I have seen so far in a mobile phone; even if when you manage to connect your laptop to it and then disconnect from it, to use it a second time you need to reboot the phone because there's no way the hot spot will start again,
- sending emails with big attachments fails very often and blocks the whole internet connectivity until they are fully sent,
- during a call, screen turns off and sometimes won't come back up again,
- the phone wouldn't unlock until you restart it.
The list can go on and on. Definitely it is not something you would expect after spending $700, no matter how big of a fan you are.
