Your N7 should be doing much better. My Tab 3 7.0 LTE is 2d 2.5h with 1.5h screen time and GPS/wifi/bluetooth/cellular all ON the whole time, 40% time without signal on the cellular....60% remaining charge. All-use plus idle, I am averaging 0.8% per hour not 2.5% per hour. In airplane you should *definitely* be less than 1% per hour even on an N7.

7% battery after exactly four days. Everything on the whole time, 5.5 hrs of screen time and 33% cellular time without signal. Final tally almost perfect 1%/hr all-use average. Active use being 10-15%/hr, if you take those hours out of the equation it's losing substantially less than 0.5%/hr idle. I suspect in airplane mode it would in fact approach 0.3-0.2%/hr.

You really need to pin down that battery loss or have someone look at it.
