Battery time 12 hours not 7 days – Pebble OLD VERSION Review

I bought a brand new pebble classic 2 months back. They claim it's battery lasts 7 days, whereas my watch's battery lasts around 12 hours. Pebble Customer Support is also not telling me why this is so. I sent them a device log but they never told me why or replaced my watch. Pebble doesn't have control over their manufacturing qualify assurance. And they are not mature with respect to after sales services. Please be wise and don't waste your money.
