I uninstalled the app and now don't have any mobile data connection
Depending on your version of Android, Battery Stretch works by either changing your APN settings or by using the disable data option.
To restore you APN settings, goto Menu-> Settings-> Wireless and Networks-> Mobile Networks-> Access Point Names and remove the batStretDisabled text from the name.
To enable mobile data, goto Menu-> Settings-> Wireless and Networks-> Mobile Networks-> and select the Data Enabled checkbox
Sometimes when I turn my screen on, data doesn't automatically reconnect
This is due to a bug in the Android OS, if you regularly get this problem, try the "Force Reconnect" in settings. However, please note if your sim card has a PIN, you may be prompted for this.
I have a CDMA phone and Battery Stretch doesn't disable my data connection
Unfortunately, at this time Battery Stretch doesn't support CDMA. However, you can still us Battery Stretch to benefit from better management of your wifi connectivity
