Ok thanks for the quick reply but is it also normal for the phone to drop from 100% battery to like 80% if I listen to music for like 30 minutes? And sometimes some web pages won't load like myspace full site or like tmobile check billing information. It just says page cannot be loaded its says it probably moved or something like that
Are you new to smartphones? This is a computer basically. Is it normal for the battery to drop 20 percent when listening to music for 20 mins...umm I'm not sure, I haven't tested that on my vibrant yet. However, I have used the BB Bold 9700, BB Pearl, HTC Evo, HTC MyTouch, and now the Samsung Vibrant. All with the exception of the BB Bold 9700, have what non smartphone users would consider horrible battery life.
Are you sure it is a 20 percent drop in 30 mins, or are you over exagerating?
I guess if you are having almost a rounded up 1 percent drop per minute you should exchange your phone. That means in 100 mins or one and a half hours your phone goes dead listening to music? You said earlier you get 7 hrs.
T-mobile check billing doesn't load for me either 90 percent of the time, it usually gives me that error when my phone is running edge and not 3g. I don't know about myspace, I never tried it.
You should just evaluate your settings, how you truely use your phone, and if you are new to smartphones give yourself time to adjust to the learning curve of how to maximize battery life. I think this is something every new smarphone user goes through. Except BB users, those suckers last days with 1 charge. Then again they dont have 4 inch super amoled touch screens, working browsers, streaming video etc etc. I mean BB can do all those things, but not very well, so most people use it just for email so the battery lasts a long time.
I think your unit is fine, but if you really need confirmation, then exchange it, and when your new one has the same problems you will know your first phone was okay, and you can sleep rest assured all vibrants are the same.
