I found that GSM Modem's current is unstable. Sometime it only is 5-8 mA current in sleep mode. But 16-18mA current often appears. I try to set S3C2442's pins which connect to GSM to input function The current is the same. I think the GPIO setting isn't a problem. The total current is GSM modem + 3~4mA Therefore, I sometime found the total is 9mA with GSM. But the normal suspend current is 20mA. I think we need someone to check GSM modem's consumption.
