my nexus 7 is about 5 months old. up to now, when i charged it up, it gave ne aprox 23 hours. Today it is only giving me 11 hours. any ideas guys.
So, a few of things to consider:
One final point, your tablet will automatically get an update to Android 5.0 in the next week or so. This new version should be more efficient and offers some battery life extending improvements. We should all get some extra tablet time once that is delivered to us.
