My battery life is from morning to second day night (two days). I have disabled Wifi and OK Google. Very important for my batery life was disable Mobvoi apps: Fitness, Health, Heart rate and Step Ranking.
Have had my Tickwatch E for only a few days and the battery life is horrible. Slept with it on my wrist at 100%. Woke up to 48%. That's unacceptable. My Fitbit kept a good charge for at least 3-4 days when not very active. This needs to be addressed. I like the watch but I need to be able to use it.
