I thought everything was resolved after the last update (I updated on release day), but starting today, my battery has started draining quickly. I first thought it was because of the wifi issues I had at a meeting/event I was attending - the LTE was awful and I had trouble getting into the wifi verification page (I had arrived at the event with a 96% full battery and within 30 minutes, drained down to 85%). By lunch, it was at the 50s. I partially charged my phone after lunch, at around 2 or 3 (to the higher 80s), but three hours later, it's at 70%. I have not been receiving THAT many emails or Tweets/other social media notifications. On a typical day, my battery drains down to the low 90s/high 80s around lunch and down to 40% by dinner. When it gets plugged in again at night, it's at 20% or slightly below. Has anyone else experienced this or should I give it another day or so?
