Flex 2 15" battery

[jacktheToaster]

I have a Flex 2 15" laptop and the battery goes down insanely fast. It went from %100 down to 7 in 45 minutes flat and I don't have full performance on. Do I need to take it back?

Hi,

That doesn't sound to be correct, according to Lenovo's website for the specification of your laptop the battery should last up to 6 hours on regular use.

First I would suggest doing a battery calibration first.

If this will still not work, I would suggest contacting Lenovo first.
