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.

其中一个主要的，也是最容易应用的技巧，就是关闭设备中耗电量最高的元件。克里斯写道：

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

对于那些好奇为什么克里斯要等到电池电量低了再充电的人来说：在电池性能开始下降之前，电池的充电周期是有限的。旧的镍镉电池存在电池内存问题，但仍有基于充电的寿命周期（也就是说，一些读者仍然发现镍镉电池是满足他们需求的理想解决方案）。较新的锂离子电池不再遭受电池内存问题的困扰，但它们必须有一个固定的生命周期。虽然性能明显下降需要相当多的充电周期，电池实际需要更换也需要相当多的充电周期，但如果你真的想延长电池的寿命，那就值得关注了。

John Weiss使用快速开关关闭**上的高功率项目：

I use toggle ic*** 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.

这些选项中的大多数都隐藏在系统菜单中，因此在appstore/Marketplace中搜索快速访问小部件是值得的。大多数情况下，我们需要**接入，但不需要Wi-Fi和GPS，关闭这两个功能可以显著延长电池寿命。

Michael跳过了整个开关程序和升级：

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比简单切换更进一步，并使用Tasker管理其连接：

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.
