Great phone! I am always Sony fan. The phone is a good size fit exactly I want on my palm. Believe it or not, the phone is last nearly a week with my regular daily usage.
Phone is fine as expected with OS performance and size however battery runs out rather quick with 1-2% per hour if left idle screen locked. If used of course will go more maybe 7-8% per hour or more depends on what you do. If you are heavy user it will last 6 to 8 hours at best.
This is just the default OS as different Launchers will use more battery
great battery , good camera, low light cam so - so , Android Pie 9.0
Battery lasts for a long time. Apps run smooth, no lag. The camera takes good pictures, with the possible exception of low light. You have to take your time and focus properly and low light pictures come out acceptable. It's upgraded to Android 9, not going to 10
