i guess i'll try juice defender later, but do i have to upgrade from basic juice defender to allow certain apps to run data? i use google voice for texting since i dont have texting plan, and i noticed i dont receive texts if i have juice defender on
google voice requires data i do believe, basically juicedefender in it's default state just disables your data connection when the screen is off, while the screen is off, during that time, every 15minutes juicedefender then turns on your data connection for 30seconds, to allow apps to sync, email, etc, and it will leave the data connection on as long as there is still data flowing, once 30seconds is met(longer if there is data traffic), or data is no longer being sent/received it then shuts the radio downs back down, the cycle then repeats
upgrading only gives you certain extra features, such as more customization of how long the radio stays on(you can change the 30second period to longer i believe), ability to use peak schedules(during the time set, it will check more often or just leave data enabled), night schedules(same thing), the ability to automatically turn wifi on/off(uses cell tower location data to know when you are home/at a spot where you were connected to wifi)
if you require text messages immediately, and you use google voice, sadly juicedefender will not be for you, as i am fairly sure it requires that data connection to be on all the time to receive them.......if you can delay getting those messages until it syncs, or you turn your screen on it may be worth your time to check it out...........i am actually unsure if google voice requires data to make calls(i'm sure it does), as that would also be an issue with juicedefender on the receiving calls end, as again if your datas off, you wouldn't get the call
that being said, i did a test last night, and didn't plug my phone in, i was at 73% at 2am, my phone became unplugged at about 5pm that night(light use inbetween that time, GPS navigation with Waze, checking some stuff, few videos etc)......it is now 11:14am and i am awake again, and i am at 65%........if you can live without your data connection 24/7 it really does help
and again as the poster said above, it just automates some stuff that you can do manually, if you'd prefer to do it manually all the time, you can achieve the same results, but i for one am lazy, and like the auto-enable/disable wifi that the ultimate version brings
it sounds like it might not be for you with how you use google voice, but i hope my explanation explains a bit better about the pro's/cons of it for you
i forgot to answer your question, i THINK you can control apps in the basic one, you just need to enable the 'advanced' setting i do believe, it's been a while since i had basic though
btw, just checked, 18hr, 17min, 35sec on battery, and i am at 64%
