title: How to measure the CURRENT voltage and current from the battery of an android phone?
body: <p>I am working on a NEXUS S phone
   I wanted to read the current supplied by battery, I suppose that this can be done reading a system updated file on the phone.
  I read somewhere that it can be done by reading a file at</p>
  
  <p>/sys/class/power_supply/battery/batt_current</p>
  
  <p>but there is no such file in this phone called batt_current or current_now......
  (On other phones there is one!!)
  Though I could see a file named voltage_now which showed me the current value of voltage supplied by the battery </p>
  
  <p>Does anyone know where can I find the CURRENT current supplied by the battery....</p>
