So what exactly does the "Power saving" toggle button actually do?
It's one of those functions that, in addition to an on/off switch, if you tap on it, it will take you to a sub-section with individual options, as well as a link to "Learn about power saving", an explanation of what it does.
I'm going to check that out jwither. I started using it myself Sunday and didn't notice any difference in overall performance.
I've seen a big difference using airplane mode. Especially when I'm at work, I work in a brick building so signal is sketchy at best. They phone isn't searching for a signal the whole day so that seems to help.
Separate names with a comma.
