Earlier this week we asked you to share your tips and tricks for squeezing more juice out of your mobile devices. Now we’re back with a roundup of those battery-extending tips.

One of the primary, and easiest to apply tricks, is to toggle off the highest power consuming elements of your device. Chris writes:

I usually turn my screen brightness to the lowest setting and only charge when the battery is about to die.

For those curious why Chris waits until his battery is low to charge it: batteries have a finite number of charge cycles before the performance begins to degrade. Older Ni-Cad batteries had issues with battery memory but still had a recharge based life cycle (that said, some readers still found Ni-Cad batteries to be an ideal solution for their needs). Newer Lithium Ion batteries no longer suffer from the battery memory issues but they to have a fixed life cycle. While it takes quite a few charge cycles for performance to noticeably degrade and quite a few more for the battery to actually need a replacement, if you’re trying to really extend the life of your battery its worth paying attention to.

John Weiss uses quick toggles to turn off the high-power items on his phone:

I use toggle icons to keep my 3g network, wi-fi connection, and GPS turned off. When I need them I turn them on, use them, and turn them off when done.

Most of these options are buried within system menus so it’s worth searching the App Store/Marketplace for quick access widgets. Most of the time we need cellular access but not Wi-Fi and GPS—turning just those two off can significantly extend battery life.

Michael skips the whole toggle on/off routine and upgrades:

Rather than fiddle with the settings and lose functionality, I bought a third party battery. They’re less than $20, and some of them last twice as long as the stock battery.

That’s a decent solution, although most of our newer electronics have pretty good batteries, historically we’ve gone the upgrade route. It doesn’t make sense to use a 1200 mAh battery in your cellphone if you can get a cheap 2000mAh battery that fits in the same space.

Xaviant goes a step further than simply toggling and uses Tasker to manage his connectivity:

For my laptop I made a hybrid power setting between low and max performance. On the battery it’s basically set to power saver, limiting processor state to about 80%, automatically turning off the display after 1 minute (If I happen to walk away and forget to close it), enabling sleep on lid close, hibernation after 30 minutes, things like that. I can usually get about a good 9 hours out of my laptop with these settings.

For my phone (Android), I use Tasker to turn off things like Wi-Fi and Bluetooth after about 10 minutes of no connectivity, and also to turn off when I go to sleep. I keep GPS off most of the time because I never really use it, And I usually get about 18 hours out of it before I ever need a charge. On top of that I also bought a universal backup battery from Duracell, just in case I ever kill it playing a game or something.

My iPod Touch is usually set to airplane mode when it’s off the dock. Just listening to music, it lasts me about 3 days before it ever needs a charge.
