Can a bad SIM drain battery in 90 minutes?
So I replaced my battery because bu 3GS was going dead from a full charge in about 90 minutes with an always warm case. The new battery didn't help... But since I need a phone I bit the bullet and got a new phone.
I wiped the old phone, and put in a Hong Kong sim card (my normal one is from Macau), placed all my apps back on it, and charged it up.
I have left it unplugged for 30 hours and the battery is sitting at 91%. The new phone (with the old Macau SIM card) is a iPhone 4, and it's going through batteries quickly (about 6 hours - 8 hours, including juice pack)
Is it possible for a SIM card with wear and tear to somehow drain a battery stupid quickly? OR is it possible that there is some strange carrier setting that changed with a new carrier profile that is killing my battery? Any thoughts on how to diagnose?
