The most disturbing behavior I encountered concerns the standby consumption, that manifests different slopes even if the same conditions was applied (no wifi, 2.5G connection, PR 1.1.1). In the first plateau, 6:30-10:30, the slope is almost flat, ideal. The second, third, fourth, and fifth plateaus, occurs with the same slope, dramatically slanting. The latter plateau shows an average slope. Sometimes it's enough to just switch on and off the screen (with the sliding button in the right side) AND NOTHING ELSE to make the slope worst! What's the explanation??
