My Samsung Galaxy phone is usually pretty decent on battery life and consumes what I would consider a reasonable amount until it gets into a situation of low signal fading in and out of roaming.
Then, I don't know if it's an Android bug of a Samsung bug, but the dang phone suffers from what would appear to be separation anxiety from the 3G network and starts trying to reconnect continuously and the battery drains faster than a broken car radiator on a hot desert road.
I've tried everything and the only solution I've come up with that's simple to turn on and off again is to put the phone in Airplane mode until such time you change locations where there's a substantially better signal strength.
Has anyone else run into this and maybe found a better solution?
I think the real problem is I need some kind of app that monitors the battery and alerts me to the problem before it's beyond hope, which has happened a time or two already, and maybe even put the phone into airplane mode automatically when it detects a massive drain before it dips below 50%. When the screen is off and there's no phone call in progress and the GPS isn't active, it's kind of a no-brainer to detect the battery is in crisis when it's plunging faster than blue ice falling from an airplane lavatory.
