It looks like a nice phone, but I cannot tell you anything about the battery as I don't own one.
I also haven't looked at it in depth yet as what Apple does in regards to the new iPhone will determine which way I go.
That said, I have no binding loyalty to Apple. I use the products of theirs I like and that's it. I'm not bound to their ecosystem and neither are the other users in my house. The only service I use is iMessage and that's easily replaceable with SMS.
Facetime is nice every once in a while but I usually just call my wife if I need to talk to her.
My newest Mac is a 2006 MBP which is limited to Snow Leopard only so no iPhone I own can sync to it, except maybe my 4s and 5 which I don't sync anyway.
So, again, really not bound to Apple.
Understood, mistaken the fact that you already owned a H P10+. Thanks for sharing it! That gave to me, probably a good direction where should i be this fall!
