Prior to today, I hadn't had any problems with 2.3.6 battery life. Unfortunately, that no longer seems to be the case. Today I managed only 11 hours and some odd minutes before hitting 8%
I was at work for most of the day where I was connected to wi-fi, but rarely using my phone for anything but a text or two here and there. It was just like any other day at work. If anything, I probably used my phone less than normal, as it was somewhat of a busy day.
So my day consisted of a web page here and there, some moderate texting, and a few minutes of Doodle Jump. At about 10 hours in, I took a screenshot of my battery-usage-graph-thing which I will share. Wi-fi was on all day as usual, but today it took quite a toll on my battery. My battery life had seemed lessened, but generally comparable to 2.3.4 (or whatever the previous version was, I forget). Today it's not even comparable. The only time I killed my battery so quickly was with heavy gaming and browsing throughout the day.
I don't know much of anything about kernels/roms/modems, but I guess I'll start looking into them =\
I apologize for the gigantic picture, but I don't know how the hell to post it smaller. I tried adding it as an attachment, but it was too big or something.
