Hi all! Im 39 years old and purchased my first tablet at Wal mart. It is the hip street Flare 3. I love it but one problem when the battery gets low it starts draining super fast. When it hits like 13 percent it just goes to 0 in like 10 seconds. I have only had it 10 days. Should I take it back and exchange this -- or is this a common problem? The charge lasts about 7 hours when im using it for music and videos and reading. I really dont know much about tablets so would appreciate any advice as i still have like 3 days to bring it back and exchange it.
