Bose NC 700 not charging completely
I have purchased Bose NC 700 headphones last year and I already got it replaced under warranty coverage because of issues with Bluetooth issues. Now in the new headphones I observed headphones is not charging completely to 20hrs. At first it got charged till 19+hrs and then it started going slowly and now it's getting charged only till 16hrs after keeping the charging ON for a overnight. I am totally surprised to see this many number of issues with such a premiere headphone.
Also I have already tried universal solution which Bose provides for any problem, i.e resetting headphones a couple of times and it's still the same. My worry is complete charging capacity is going down slowly.
