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.)
