Data connection won't be enabled when screen on or only works sometimes?
If you have a task killer app installed, please add this app into task killer's ignore list so it won't be getting killed. This problem may also happen when you are in a low signal zone. In this case, the phone takes longer time (couple minutes) to register to the data network.
Streaming music will stop if 2x Battery is enabled.
Please add streaming app to the whitelist. You can edit the whitelist from Settings > Whitelist.
Don't add VOIP app to the whitelist. Since VOIP app is running in the background all the time, adding it to the whitelist will stop 2x to toggle Mobile data, which won't save any battery.
Skype app will stop if 2x Battery is enabled.
When you turn off the screen, 2x Battery starts to monitor the data activity and will disconnect the Mobile data if no more data activity. If there are still some data activity over the Internet after few minutes, 2x will force disconnect the Mobile data for saving the battery, which will stop VOIP apps. If you use Internet telephony apps, e.g. Skype or Viber, please turn off the "Force close bg data" option from Settings > More settings.
Some apps did not sync the data after I installed this app.
This app extends battery life by periodically toggling the always-on Mobile data connection. If apps scheduled a synchronization task at the time that data connection is disconnected, the task won't be executed due to no available Internet. Specifying a small enable interval value may reduce the disruption.
Why doesn't it work on my phone?
Android does not provide a method for 3rd apps to switch off Mobile data, so we have to use undocumented API to manage Mobile data connection. The API works on most 2.1 or above devices. If it doesn't functional on your device, please email your phone type and Android OS version information to us.
Do you support app 2 sd?
No, app 2 sd is not enabled by default. If you install this app on the SD card, it may not work anymore. This is the limitation of Android.
Will this app change my APN(Access Point Name) settings?
No, we don't touch the APN settings. To enable/disable the Mobile data connection by changing APN name may mess your APN settings. We use a different technology to manage your Mobile data connection. It's a better approach than other similar battery management apps.
The estimated empty battery time is not accurate.
Android devices do not provide empty battery time information. The estimated empty battery time is calculated based on the information of how you use the phone in last one hour. This information is for your reference only.
