My apology if I miss the answer in some other threads. I didn't have this situation until Twix and now, DOTS. When I check "Battery use", I see a bunch of programs in there, without turning them on or using them like Android OS, Media, Swype, Market, Dialer ... In Twiz, even when wifi is on, it won't actually connect unless I manually connect it and it disconnects when the screen is automatically turned off. I had great battery life. I drained the battery and recharged before I flashed ODIN. I pretty much did everything the same way as the previous times I flashed a new rom. I drained the battery again but that didn't seem to help. I installed Advanced Task Killer. A while after I kill selected apps (a long list), the apps tend to turn on on their own. I had unchecked "Background data" but that didn't help either. Wifi connects unless I literally turn it off. (That wasn't the case.) Is there a few check marks that I miss? Thanks for your help. http://androidforums.com/support/907-shutting-down-programs-conserve-battery.html Not sure if my problem is similar to this.
