Well, gee, I'm glad I bought a Turbo so it could last a half a day while FB Messenger runs and I haven't even used it today. A co-worker brings me her phone today. "My phone was at 100% this morning... it's down to 52% already". As I'm poking around on her phone, the battery is draining slowly right before our eyes. wtf? Down to 49% literally in 3-4 minutes. I get to battery and see FB Messenger eating a whopping 30%. She hasn't even used it today. Then I look at my phone. I used Messenger yesterday and have since rebooted. To my amazement I see this: 34%?!?!?! Seriously??? I am just blown away here. Anyone with FB Messenger care to check battery stats for me?? /uninstall Another co-worker who HAS BEEN using FB Messenger today on her S5 doesn't even show Messenger in the battery list. She is on Lollipop. User #1 is on KK. Edit\ User 1 not on battery saver. User #2 is.
