Pdanet battery drain even when "charging"

When tethering over WiFi you are using two power-hungry radio transmitters. If you switch to USB, you will cut out nearly half of that power drain. Also note that turning off the screen will save a lot of power.

Definitely agree. I use USB tethering on my 3GS and notice very little battery drain. My USB tethering has been activated by installing MyWi.

I had the same problem and discovered that there is an internal heat sensor that deactivates the charging when the phone gets too hot like while using pdanet. This may not be a factor in colder climates but here where room temps are generally 80 degrees, that is warm enough to cause a problem. Just set your phone on a cool surface like stone, marble or granite and there will be no more trouble with charging while using pdanet.

That sensor may be set for different temps in different phones which is why some people have an issue and others don't. BTW--am using a Mac
