don't do that unless you are comfortable with charging the phone every 4-5 hours btw, i don't think any sip voip app in market provides good enough voice quality

wifi待机状态应该比较省电。 voice quality取决于很多因素,对于voice over 3G来说,有两个主要问题,第一是上 行带宽不是很够,第二是latency大,人的耳朵对于单向latency最大的忍耐度是150ms ,如果超过这个,听起来就很不爽了

en i'm talking about voip over wifi, i tried several apps, none of them has good voice quality. and most of the apps have echo problem.
if you keep wifi always on, it might prevent the android system from entering standby to save power, i.e. lower the voltages or even power gating several devices.

i'm not sure, so i use 'might', heihei for iphone, there is only one system, one vendor for android, many vendors, and vendors sometimes modify the system, sometimes inject new bugs... it's complicated :(
