棒棒糖isPowerSaveMode总是返回false [英] Lollipop isPowerSaveMode always returns false

问题描述

我想知道PowerSaveMode是否已激活.我正在使用此代码:

I am trying to know if the PowerSaveMode is activated or not. I am using this code:

    PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    return pm.isPowerSaveMode();

但是它总是返回FALSE. 我只尝试了5.0.1的Samsung Galaxy S4，因为这是我唯一拥有的Lollipop设备. 有提示吗?

But it always returns FALSE. I have only tried with a Samsung Galaxy S4 with 5.0.1 because is the only Lollipop device I have around. Any tips?

推荐答案

我发现三星以不同的方式工作. 像往常一样，Android喜欢棘手.

I found out that Samsung works in a different way. Like always Android loves to be tricky.

bActivated = Settings.System.getString(context.getContentResolver(), "psm_switch").equals("1");

我也读到HTC必须这样:

I also read that for HTC has to be this way:

bActivated = Settings.System.getString(context.getContentResolver(), "user_powersaver_enable").equals("1");
