Ok... I just joined here to try this and show my results after some curiosity to try it.
First I just want to say that... Yes, these configurations are doing something and I am getting more battery life.
I set yesterday at 2 am EST the configuration as showed previously in the image using OC Widget and see the results in the morning.
Battery at 62%, 4G Off, BT Off
My EVO and I woke up in the morning, when I saw the screen I said: "Holy Sh!+" is still at 62%, 3 seconds later I said "Holy Sh!+ the alarm didn't work, I am late to work!" but after using for a couple of minutes the battery suddenly started draining fast the next 3 minutes it lost like 5%, but during my driving to work and using the phone to check a couple of mails and browse the discharge stabilized.
I am not sure yet if the configurations made it with OC Widget made some process to not run while the phone and I were sleeping I still need to confirm this. I have set the alarm again a couple of minutes ago and let the phone sleep to see what happen and the alarm worked, meetings alarm, received calls, got mails. I am still not sure why didn't work this morning. But definitely this configurations are working. Here the images:
I will keep testing this configurations.
One thing for sure is the 4G is taking so much battery, yesterday I run out of battery around 2pm and conected to my PC with the usb cable to charge it. I got like 60% when I head to a meeting and during 1 hr it lost like 30% and I just used a couple of times to check email and some meetings. I know is not the same charging the phone thru usb rather the AC but then turned off the 4G and the discharge stabilized.
I think with this OC Widget configurations and turning off some things when are not needed, we can get more battery.
Thanks for sharing!
