Wife's Ally, which she loves, has recently turned into a battery muncher. For a few days, since a recent update, she'll have it fully charged, check email, send a few texts, take a short call or two and then lay it down. Yesterday afternoon it was fully charged and she hardly used it. This morning it was flat. Any suggestions? We're heading for the Verizon store this evening. I'm not android smart...have a BB myself.
