I normally can go 3 days of use with my GG before I need to charge it. It was 100% charged this morning, I put my GG on around 7:30am and by 3pm it was alerting me to charge it since it had dropped to 15%. That is not normal battery use and I actually was NOT getting my gmail notifications through out the day other than a few here or there. The only thing I have done recently is update Gear Manager over the weekend.
