For the first week I turned my phone off every night to charge and back on in the morning. The last several days or so I have left it on, charging while on for only a few hours as needed (I have been getting great battery life 24-48 hours, albeit with light use so I was doing it in part to test that). I had an old flip phone before this that I hardly ever turned off, but I was wondering if there is any harm in always leaving a smart phone on? I wouldn't do that to my laptop, so is it okay to do this or should I let it power down and "rest" more to conserve the electronics and the battery?
