Oh I've been using the white charger only for a couple weeks now. I move it from room to room if I have to. I've noticed no difference. I am going to continue doing it though in case it affects the overall health/life of the battery over the long term.
As I mentioned, I'm dealing with other battery drain issues. But I can say after a couple weeks I'm pretty certain it has made no significant difference in daily battery life.
I'm trying something else right now to try to figure out my post-update battery drain issue (not to derail the thread, but wanted to mention this within the scope of my overall battery problems). This is a shot in the dark and I don't see how it would matter, but I charged my phone yesterday evening without the Otterbox on (happened to be already off so I could remove the back to provide battery info to ATT). Right now I have 14 hours off the battery, 3.5 hours of screen time, and my battery is still at 58%. So I'm on pace for the 22-26 hours with 6 hours of screen time I was getting before the update (around the time of my last update my battery life decreased dramatically, to where I was only getting 12-15 hours and 3 hours screen time).
I'm wondering if there is any chance that the Otterbox could impact charging? Or maybe using the white cable over time has gotten the charge/battery back on track?
I assumed there was a problem with the update. Then again, the last 58% of this battery may drain quickly and I won't wind up getting 24+ hours and 6 hours of screen time.
Either way, I'm confused about what is causing this, like I said, I assumed it was the update, but if I wind up getting 24+ hours on this charge like I was before, maybe it is related to the Otterbox or charger?
Whatever the case, I hope it keeps giving me 6 hours of screen time. That is what I expect out of the phone now because for the first few weeks, that is what I got consistently.
