iPhone 4S/IOS6 - battery drain after the camera usage I just discovered that my iPhone4S/IOS6 battery drains too fast after I use the camera. So:


After the fresh restart the phone lasts 3 days - when not taking photos or videos.
Even if I take one photo (and of course, stop the camera app) the phone will drain the battery in 1 day.


The GPS (triangle icon) disappears after I stop the camera app. 

I tested the above several times - enough take one photo (or short video) and the phone draining the battery in 1 day. When I restart the phone after taking photos, the phone will continue okay and lasts 3 days.

Are there any hints about this specific battery-drain problem? (I have already read the general battery hints.)
I don't think its the GPS, do you have Photo stream turned on?  That will upload your pictures to iCloud.  One thing you can do is check usage to see what is doing on after you take pictures.  Is my iPhone 5S draining battery too fast (and is it due to process mediaServerD?) has good information in the OP about checking what is using your battery.
