Actually, you said no more than once a month. Yes, it takes 2 hours to charge a phone to 100% with a mains charger. that's why the charging circuitry in the phone turns off charging after 2 hours, whether you leave it plugged in or not.
I'm really not sure how charge time directly relates to battery drainage.
As I stated before I've been using iPhones since the early days of the 3GS. This coincides with iOS 3.x I now have a 4S. 400, 1000, 1,000,000 cycles or not a phone doesn't lose up to 50% of its ability to hold a charge overnight. Maybe 1 phone, but usually not hundreds (that's just including the poeple bothering to post to this thread and disgregards those assumed thousands of users resorting to scream profanities in their bathrooms as they ready themselves for work while their phone is dead) due to user negligence or error. My ability to do so DIRECTLY coincided with updating to 6.1.2, AND 6.1.3.
My 3GS maintained a near perfect battery life for over 2 years with over 500 cycles on it because I followed apple's battery maintenance tips and suggestions. I have only done the same with my 4S.
I have followed any and all tips/instructions available in this thread up to and including factory reset/restore. Restoring to 6.1.3 results in the same battery life. Horrible.
In my experience I cannot call this a user issue. This has to be software related, and also most likely related to specific hardware in specific phones in date and place of manufacture. As some have said it may be a specific app that we recently updated but restoring the phone and reinstalling everything we use simply recreates the problem.
Whatever the case, I started with iOS 3.x and got myself all the way to 6.1.2 before having a single battery complaint.
Eagerly awaiting 6.1.4.
