Not sure what the problem may be. I got the Seido 1750 battery. I make sure it is fully charged. However, it appears to go "down" faster than the original OEM battery. Is the battery defective? Should I send it back? It has been off the charger 37 minutes and 1 second and it appears about 10% of the charge is gone. No, no applications running in background-GPS is not on-no Mobile networks, etc-I always have those turned off. I use Advanced Task Killer and kill all apps in background once I am done with them. How much life should I get with the 1750 battery? How much should I get with the OEM battery? Any assistance is appreciated.
