My phone wasn't plugged in overnight and I've used it to browse and watch YouTube since I woke up about 4hrs ago. Right now the battery is at 97%. When I use the phone at work to browse emails on my 15min break, it goes from 100% to below 90% during that time and that's when it's not in airplane mode. It looks like the battery drains fast, atleast for me, when it's connected to my cell network or when I have it all switched on to use as a phone. Has anyone else noticed this?
