So, this has been talked about at some point on this forum, but after suffering through bad battery life days after bad battery life days, I decided to try to pinpoint exactly where my battery usage is going on my iPhone 4S running 7.0.2 - I deleted both the FB & Messenger apps. The results after one day is stunning, at least for iPhone 4S standards. I'm now at 4 hours or so standby and 3 hours of heavy usage (Google music streaming the entire time; tweeting; video watching from The Verge, Engadget, CNN periodically; Pocket article viewing) and have 51% remaining. That gets me at the purported 6 hours or so of screen time internet use for the 4S - nothing to call home about, but definitely gets me that extra push until I get the phone on the car charger and back home. I probably will be able to squeeze even more out, as I forgot my iPad at home and usually use that for music streaming. What I'm getting at is why is Facebook apps not being talked about as much as being part of our battery deterrents? Surely there's more that goes into battery usage like network performance, brightness, media consumption type, etc., but deleting of 1 or 2 apps giving a 40% or so battery increase? That's substantial. Of course, this isn't a thorough, scientific test, yet real-world, dumbed-down tests like this is sometimes what gets the ball rolling, right? Just thought I'd share what I've noticed and if others have noticed the same on their iPhones too.
