Hi, I bought Tetherme so I could use Bluetooth on my iPad to connect to my iPhone 4 (4.3.2) for surfing. While it works remarkably well, I've noticed my iPhone gets very hot and tends to drain the battery much faster. I'd say around 1% every 3 minutes. How does this compare to native tethering? Is there anything I can do to improve it? I've turned off location services and other obvious things, but the heat has me concerned. Thx.
