Guys, I have started to notice a very strange thing.. On some days my battery life seems to be on pace for 10 hours, then a few hours later, using the exact same programs, notice that it drains relatively quickly.. All push and location services are disabled, ping is disabled, and the advanced mail settings are set to manual. Screen brightness is set to 50 with auto adjust. Here is an example: Last night, after noticing some quick battery drain in the morning, I played around with Safari, watched some videos, used Flipboard and other news readers. I timed 10% usage and got exactly 1 hour - Awesome right? This morning, all I did was use Safari and browse Flipboard, and in 15 minutes went from 60% to 54%.. Well off the pace from just the evening before.. I did primarily use Safari..Perhaps I'm over-analyzing, but can Safari drain battery more rapidly than other programs? Very strange to say the least.. Anyone experience anything similar?
