Hello all! This is my first post but I have been reading the Droids Forums for a while and many of you are very knowledgable and helpful! Anyways, I recently bought a Droid 4 and it definitely has the lowest out of the box battery life of any droid I have used. I have played around with battery saving apps such as JuiceDefender, as well as Smart Actions, the built in Task Manager, Advanced Task Killer, and GSam Battery Monitor to view battery stats but these have all seemed to have little effect, some more than others. Thoughts so far: *Battery saving apps work decently at first but then they start to mess up the data connection so I uninstall *Smart Actions is limited and has helped minimally by disability Data Sync when the screen is off, as well as disabling the mobile data connection (3G/4G) when Wifi is connected. *I cannot tell if the built in task manager or advanced task killer is helping - however: Android OS has gone down from about 30-40% of the battery use to 10-20% of the battery use - this could be helping but it doesn't seem to make much a difference *The battery stats show that the Kernel is taking up to 15% of battery life and even Text Messaging takes up to 10% of the battery life *I almost always have bluetooth and GPS disabled... and wifi when I'm not at home **I understand that the battery drains because I use my phone a lot however my friend has a Droid Razr (NOT MAXX) on ICS and the battery life is much much better than my Droid 4 Any and all help, advice, and tips would be greatly appreciated!! I would like to know which apps, built in apps, or setting to use/change to make battery life battery or more efficient.
