Iam using xperia c5 ultra from 4 months, as of my opinion about the phone is good the best part about the phone is the screen size, actually its very big, even its big it can be handled with one hand. Phone performance is good but some times laggy I played some heavy games on this it worked well but some times it gets lagged.
The biggest issue I’vve faced is the battery backup, it drains a lot while using internet 2g. 100% battery comes down to 30% with in one hour of usage continuous. And the soumd quality is good but not great.overall above average product.expected a lot
