Q: iOS 6.1.3 battery drainage
Last night I updated my iPhone 4S to a iOS 6.1.3 and now it drains my battery in extremely fast manner. As I started signing in to write this question from my iPhone I already lost 13% of my battery. I never had a problem with a battery and ive been using iphones since the first one. i miss my morning class because of it because my alarm clock didn't because my phone was dead. Please fix it or have no choice but buy Samsung GS4
iPhone 4S, iOS 6.1.3

I can confirm mine is now fine.
Go to settings
Mail, contacts, calendars
Go into iCloud and turn all switches to OFF one by one make sure you save all to iPhone though not just delete
Then go to each other mail account and repeat this procedure again making sure you select keep on iPhone not the delete option
Once they're all turned to off check your calendar to see if everything is missing off it and then you need to do a hard reset by holding the home button and the on/off button until the phone turns itself off.
Once it's come back on go back into settings and mail and turn each switch (or each you want) back to ON.
Then make sure all your apps are closed lock the phone and leave it for 30 mins and then check the battery hopefully if like mine it shouldn't of dropped at all
This worked for me hopefully it will work for others out there
