This is my first smartphone, as well as my first Android phone, but I'm amazed at how quickly I can go through a battery with the Triumph. I haven't been able to stretch the battery for more than ~8 hours with a variety of usage (watching a few youtube videos, playing a game for 20min, a few phone calls, light web surfing, etc.) and I'm wondering what are reasonable expectations for an Android smartphone and is this an issue with my usage or do I possibly have a defective battery or phone? How can I conserve battery life without turning off all the useful features and hamstringing the thing, effectively turning it into a dumbphone?
