Faulty new phone battery?

Yesterday, I got the battery replaced on my Sony Xperia Z3. Which is 18 months old

I put my phone on charge and it shows 100% charge then remove the charger and its 36-38%.

Why does my phone do this?

Tried different cables, usb adapters and plug points.

Earliest I can take phone back to shop where battery was replaced is Tuesday and they have to order it. Independent phone repair and accessories shop.

    Make sure you get a genuine Sony battery. I've tried generic batteries in my Nokia and got the same effect you describe.

    Could be a fault with the battery. Doesn't necessarily mean it's a fake. But I would refrain from further excessive charging just to be on the safe side. Take it back but maybe phone on Monday to tell them the issue.
