Best methods for conserving/extending Droid 4 battery life?

[TisMyDroid]

I also have the ultimate version, which I no longer use... only because I have found that smart actions actually has done the same job more efficiently. JD worked okay for me and improved my battery life but for some, it may actually make it worse because you really have to know what to set up, how to set it up and understand the possibilities.

The same holds true for task managers. They can be effective but only if you use them in a few specific ways. Many people will set them to auto kill and what happens is the app constantly runs to kill apps and processes that immediately start back up again...using a lot of battery in the process. I do think task managers can be helpful to see exactly what is running at any given time and to individually kill a run away app but other than that they can be more harm than good.

IMVHO.

I un installed JD again. It seemed to make the data connections worse. It wouldn't connect and also once made my phone have no signal at all for over 45 minutes. I didn't even know it until my voicemail kept coming in and I checked the bars - no bars and the crossed-out circle icon. Had to reboot.
While it was working it showed battery improvement of 1.12 - all the data connection hassle wasn't worth it.

I too have been chasing erratic battery problems on my Droid4. My problem appears to have been the auto update settings in the Google apps store. My solution was to go to the apps store, tap on the Android menu, then settings then uncheck all boxes

Hope this helps someone

Download a custom rom then turn off 4g when you don't need it.

You don't need a custom ROM to toggle 4G.

It's not a regular menu option anymore, but you can use one of two free apps - LTE OnOff or Phone Info - to get into the internal menu for the phone.

Then, scroll down to the menu which should be set for "LTE/CDMA/EvDo" if the phone is in 4G.

Selecting "CDMA only (PRL)" gets you into 3G after a short wait, and go back to "LTE/CDMA/EvDo" to 4G.

This has made battery life actually reasonable. The phone is still pretty fast in 3G, and I don't need it to be in 4G if it's in my pocket doing background syncing.

I generally stay in 3G on battery all the time, unless I know I need 4G for something. I turn 4G back on full time if I'm plugged in.

Does having WiFi on (and a connection of course) supersede 4G? Or will the Droid use the fastest speed available between the two?

Wifi will be used but the 4G radio is still on unless you turn off mobile network

Wi-Fi will be preferred. Basically with Wi-Fi on, your data will not be used unless you send an mms or you lose your Wi-Fi signal.

Thanks for the tip!

In addition to lte OnOff go to smart actions and set a trigger as "display off" and the action as "cellular data disable" and even though it shuts off background data you'll still get texts and calls
