如何在使用GPS时减少iPhone电池消耗 [英] How to reduce iPhone battery consumption while using GPS

问题描述

我使用GPS实际监控是否进入了某个区域（半径100米）。

I am using GPS to actually monitor if I have entered a regions (radius 100 m).

我使用的是 significantLocationChange 和硬件GPS的混合体， startUpdatingLocation 。

I am using a hybrid of significantLocationChanges and hardware GPS, startUpdatingLocation.

由于 significantLocationChanges 不如我要求的准确，因此我只使用它们来检查我是否输入了外部圆的X m。然后我使用硬件GPS检查用户是否进入内圈（100米）。

As significantLocationChanges are not as accurate as I require I am using them only to check if I have entered a outer circle of X m. Then I use hardware GPS to check if the user enters an inner circle (100m).

它的问题是，电池很快耗尽，任何人都可以帮助我。

The problem with it is that battery is getting drained pretty quickly, can anyone help me out.
