主动 GPS 对移动设备电池寿命有何影响？
主动式 GPS 会消耗多少电池电量？没有 GPS 导航器软件的开销。 s 是的，我想每 2 分钟对 GPS 采样一次并将其保存到文件中。这将花费我多少电池电量？
我的寿命会缩短 10%吗？ 20%？ ..？
How much does active GPS drain the battery? Without the overhead of the gps navigator software. s
ay I want to sample the gps every 2 minutes and save it to a file. how much battery power will that cost me?
Will I get 10% shorter life? 20%? ..?

我认为如果不进行测量，这个问题就不能那么容易回答。但你可以测量它。尝试一下耗尽整个电池需要多长时间。一次有 GPS，一次没有。
I think this can't be answered that easy without measuring it. But you could measure it. Just try how long it takes to empty the whole battery. Once with GPS and once without.
用户会注意到这一点。您绝对不想做这种事情，除非这是用户明确意识到的功能，并且能够根据他们在任何特定时间是否认为该功能值得对电池造成影响来清楚地打开和关闭。
It will be noticeable by the user. You definitely don't want to do this kind of thing unless it is a feature the user is explicitly aware of and able to clearly turn on and off depending on whether at any particular time they think that feature is worth the impact on their battery.
在我的 HTC Desire、RunKeeper 上（GPS 始终处于活动状态），使用大约 5 小时后电池电量几乎耗尽（在福雷斯特）。
但屏幕在运行时处于关闭状态，阅读 2 小时的 pdf 会消耗大约 40-50% 的电池电量，因此在后台工作的 GPS 消耗的能量与屏幕活动时消耗的能量大致相同或更少。
当您打开 GPS 时，您必须等待（具体取决于您所在的位置），然后才能读取读数，因此，如果您想每 2 分钟保存一次位置，我认为 GPS 将在大约 25%-50% 的时间内打开。在这种情况下，后台工作最多 10 小时...
也许是关于 使用 GPS 延长 Windows Mobile 的电池寿命将给出一些提示，因为测试中使用的设备是由 HTC 制造的，HTC 是当今最受欢迎的 Android 设备制造商之一。 ..
On my HTC Desire, RunKeeper with GPS always active, battery was near to down after about 5 hours of usage (in forrest).
But the screen was down while it was running, 2 hours of reading pdf drains about 40-50% of battery, so GPS working in background drains about same or less energy than screen active.
When you turn the GPS on, you must wait, depending on where you are, before you get the read, so if you want to save position every 2 minutes, I think GPS will be on about 25%-50% of time. 10 hours of work in background would be max in that case...
Maybe the question about increasing battery life on Windows Mobile using GPS will give some hints, since the device used in test was manufactured by HTC, which is one of the most popular manufacturer of Android Devices nowadays...
