Screen and battery are two major improvements with this phone. I used to worry when going to work with 50% battery. Now I don't even care. With moderate use, I could probably go 2 days with this phone. 1.5 for sure.
For me it's the opposite.
Mine usually lasts for only 6-7 hours. Maybe 9 if I don't use it often.
Don't know if it's because I use my phone heavily or if I have a funky battery
