Watch OS 4 beta 2 battery/brightness

Watch (1st gen) with wOS4 developer beta (15R5307f) Fixed several spontaneous shut down issues, changing and syncing issues with this latest beta. Bugs on my version on my device: - Battery rapid drainage; possible contributing factors: + The backlighting unpredictability gets max bright. To the point that screen is warm to the touch, conditions: not constantly left on, regular use (occasional wrist raises, inside/outside) + Now Playing is on and looks more esthetic with multiple apps. App seems to cause screen to illuminate at wrist raises, but appears to also screen wakes at random other times. - Alerts are not always synced to the watch. Sometimes calls will ring, or text messages will ding, other times not. - App screen seems glitchy, animation is not fluid.
