I have the wifi model xoom rooted with stock rom. My battery life after the first week having my xoom has been terrible. So last week I rooted it and my battery life was tremendous because i didint have many apps on it. I've been slowing adding apps day by day and monitoring so that if I use any battery killers ill be aware. Well battery has gone to crap once again. Last night I charged it to 100 percent, i then took it off the charger and turned airplane mode on. I let it sit there untill around 10am. when i picked it up it was at 69percent charged with 70% of the battery being used from "tablet idle". I freaked out so I downloaded a screenshot app but by that time the tablet idle went down to 44percnt and 34 percent was screen on. anyone have any suggestions as to why those are percentages are so high when my tab is just chillin... btw i just downloaded baddass battery monitor. Thanks.
