I have an annoying problem with my jxd. When leaving it on standby for a long time (some hours) it becomes stuck and the screen won't awake when pressing the on button. The only solution is to push the reset button for some time. Could it be that this results from not factory resetting it after upgrading firmware (I didn't do because it wasn't mentionned in the description by jxd, also it rebooted automatically when the update was finished). If so, I guess I should redo the upgrade, if not what could be the matter?
you can try factory resetting, doesn't sound like normal behavior. Do you have anything weird running like a task killer, alternate home launcher, custom lock screen app?
Also you don't have setcpu or anything installed either do you? Setting your cpu below the normal "minimum freq" will cause the device to be non-responsive to wakeup stuff.
try factory resetting and just install the normal emulators/games and see if you can pinpoint more specifically what you are doing that is causing the freeze if it happens agian.
how is the battery lif on standby? is it even worth leaving it in that state?
and some other questions:
how do the shoulder buttons feel like when pressed? are they like the letcool shoulders? or like the gba ones? im really curious since im willing to mod my jxd to my gusto button-wise as soon as i can afford one.
stanby for me is ~5% per 12 hours with the power save wifi sleep policy in the build.prop (non-stock) also make sure you set that in wifi settings menu or just turn off wifi when not using it.
EDIT: right now sitting at 80% battery and have been away from charger for 2 days 17 hours.... wifi has been using 49% of the total consumption
actual runtime is about 4-5 hours give or take depending on what you are doing.
