Ok. I am also experiencing ongoing battery issues even after implementing the discussed solution exactly.
Let me take you guys through the events of this morning for me. My poor battery life resulted in my battery running out last night, and because of circumstances I wasnt able to charge my phone until this morning for about 30-40 minutes before I had to leave home again. During those 30-40 minutes, I found out abuot and implemented the solution procedure (install chompSMS, restart, etc.) So my battery was at about 50% when I left the house. I listened to music for about 10 minutes, and noticed the batter went down quiet a bit, to low 40's. I figured it was understandable since I was listening to music. Then I got online via Browser to check this particular thread for any updates (not for long, maybe 2 minutes). Noticed battery was now down to 36%. Getting worried, I slept my phone and didnt touch it. After about 2 more minutes, I was curious so I checked my phone - battery had plummeted to 30%. in TWO MINUTES OF DOING NOTHING! 6 whole percent of battery! Then I really didnt mess with it for the duration of my classes...which was abuot 45 minutes, after which battery was DEAD. Now I'm home charging my battery while furiously writing this reply.
Please note that i had wi-fi DISABLED during the entire morning, and is stil disabled. No GPS, bluetooth, etc. I have Automatic Task Killer app enabled, which I set to kill basically all apps besides Mail, chompSMS, Browser, Music, Clock... and like maybe 1 or 2 other essential apps. In other words, each time I wake my phone the only apps alive and running are the ones I allowed.
