Sony 3100 mAh Battery for Xperia Z3/D6603

Value for money , but as the first one I received was faulty I am only giving it 4 stars. Item was replaced efficiently.If you need a new one this does the job at a sensible price.

Good product

works fairly well decent battery life

Sold as OEM but I suspect this is not the case. My old battery was 2 years old but would last 2 days still if I kept browsing to a minimum etc.This new one will not last more than a few hours. I need to keep it on constant charge. I use the phone as sat nav. The old battery used to be able to charge/discharge at the same time but gradually build charge. This battery loses charge even when on charge while running sat nav.I'll be putting the old battery back in when I get a new replacement back.

Very fast

Perfect and actually looks and works like original battery.

The little cable of connection came separately from the battery. I don't know how to attach it back together. I opened the package recently and I realized that it came in two parts, after hours of trying to fit it I couldn't believe when I went to realized that they meant to be together and only one component - I am so disappointed.

replaced my z3 with this battery after 3 years works well.
