well, my watch and/or phone both went bonkers yesterday.
my watch drained battery at a rate of 25% an hour and it was dead in 4 hours. my phone during the same time drained 50%. no clue what was the problem. the symptoms on the watch - tilt to wake would not turn off even after turning it off in wear (it would keep toggling "on" as well in wear), watch got really hot. symptoms on the phone - wear would randomly disconnect from the watch, wear settings would not port over to the watch (previously mentioned tilt to wake toggling on even after setting it to off), and phone got really hot too.
i factory reset the watch twice, and wiped the partition cache on the phone twice using the recovery mode method, reinstalled wear 3 times, but to no avail. strangely, after i let the watch battery completely die and recharge, everything is back to normal - i have about a 2-3% drain on the watch and 1% drain on the phone per hour. i have NO clue what happened but glad its stabilized for now...
