I dont think we can really compare samsungs latest mobile running on android with last years's apple iphone 4.
Lets wait till the new iphone 5 comes or iphone 4gs and then make comparisons.
Thats funny
I have a Samsung Vibrant and can't wait to get rid of the POS. Battery life is dreadful and the OS (custom ROM) is still very green. I have a Touch and using IOS is much more pleasant than using Android. Changing ROMs, themes, etc is a huge PITA. Widgets? Overrated and battery hogs. I can look outside and see if it's raining.
I have a Vibrant, and I can probably give you a few tips.
Your battery sucks because you leave it on the charger it while it is on.
I used to do the same thing but then I bought a spare battery and an external charger.
The old battery (which was abused) lasts me less than a day. The new battery lasts me more than a day.
The proper method of avoid degradation is to fully charge it (on a charger or while the phone is off) and to not charge it again until you have used all the power it has.
I have also gotten in the habit of carrying a spare battery in my pocket just in case. There is no point to having a user-replaceable battery if you never replace it.
No, your Vibrant won't last as long as the iphon34 on a single charge.
The flip-side is that after both phones run out of power, you don't have to leave your Vibrant plugged into a wall socket for 3 hours. Insert new battery and go about your business.
I currently use my abused battery during the day when I have the phone plugged in and tether it to my tablet. I keep four spare batteries:
- 1 stays in my pocket with my phone
- 1 stays on the external charger at home
- 2 stay as back up in case I need to use the phone a lot and am not anywhere long enough to charge the dead ones (like when I am on long car trips or out snowboarding/motorcycling all day).
