I have been using the Textnow app on both my LG cellphone (Volt 2) and on my LG tablet (G Pad 8.3). On the tablet this app does not drain the battery at all, in fact, last time I checked it was reported as using <1% of the battery. On the Volt 2 phone it has been reported as high as 21%. The normal way to deal with a battery draining app is to clear its cache which I've done. I've also uninstalled it for a few hours and then reinstalled. No improvement at all. I very much like this app and would like to keep using it but it is totally draining my battery. Help.
