I've come to the conclusion that ALL Samsung touchscreen phones (esp with push capabilities, GPS, WiFi & BT) all suck battery like crazy.
This battery problem is not unique to the Moment. If you read the forums of other Samsung smartphones, they too suffer from the same battery issue.
True, you can improve battery life by turning off services like background data, GPS, WiFi, BT and other applications that require active radio transmission but that kinda defeats the purpose of having a smartphone in the first place. It changes your phone from a smrtphone to a dumbphone. Yes, you have the capabilities to do a bunch of things, but if all services are on, then your battery life suffers dearly.
It doesn't help either that Samsung seems to have a battery calibration issue with the Moment too.
Usually all the "updates" do to greatly improve the battery life is to shut down services and tone down the screen (a battery hog) and enable a "power saver" state. Updates are generally for the masses of owners that can't figure out how to do it manually, so they make it simple by incorporating all the power saving configuration canned in an "update". But to give them some credit, there's probably some code, algorithm improvement tweaks, oh and bug fixes too.
We as consumer/users have to accept the fact that smartphones that can do everything are battery hogs and may be tempted to leave all services on. And by doing so, our battery life will suffer. Because we are smarter than our smartphones, we have to learn how to conserve out battery. And that is done by smart use. Turn off services if not needed. Turn on when needed. It's kinda like a house, we don't turn on all the lights in every room. Or a car with every conceivable option, you don't turn them all on and a bunch of other analogies.
For now, we have to take it upon ourselves to maximize the battery life of our phones until Samsung and other manufacturers can design more efficient screens, chips, battery, circuitry and algorithms. We haven't seen anything yet. Future phones will be faster, have multiple core processors, graphics co-processors and bigger screens. The form factor will have to be the SAME hand held size. Therefore that calls for circuitry and BATTERY improvements.
Can you imagine all the people you want to impress all huddled around your future super fast super smartphone that can do everything.....you power it on....the screen flashes with a bunch of dazzling screens....everybody’s jaw drops with amazement...and blip... your screen blanks out? haha just a joke....
My Moment suffers from short battery life too. Conservation helps. Greatly. I figure I use it for a phone most of the time. I have the capabilities to surf the internet, GPS when needed. I check email WHEN I WANT TO, not pushed to me. If you need email as a priority, then a Blackberry is better. But for the most, I use my Moment as a PHONE.
