I also had this
problem in the past a few times and I didn’t know why.
It has to do with some programs/apps running in the background, using up your
battery – making constant contact via your internet connection.
Another possible reason:
When you update your iPhone directly via the WiFi (not via your PC), then it
only uses a ca. 35 MB small patch file and this is maybe where it goes wrong. When
you update your phone via the PC/iTunes, it downloads ca. 1GB and during the
update installation it does a couple of phone resets installing a whole new
software. Then you don’t have this battery problem.
For your information, there are Apps where you can see what programs are running in the background
and use up your battery.
However, in case you need a quick-fix which will close all your “energy
sucking” programs in the background - See the instructions here!
2 easy Steps: 1) First, double click the home-button and close
all running programs by sliding them upwards.
2) Do a forced re-boot (Don’t worry – your data will not
be lost)
by pressing the on/off button at the upper right + press the home button at the
same time.
Important: Press both buttons (ca. 10 seconds) until you see the Apple sign –
after that you can release. Then the phone re-starts, log in and the problem should be fixed.
Note: This forcible reboot method closes
all running programs in the background and it is more effective than the normal
switch-off method. Only use in case of battery problems or when the iPhone screen should freeze.
In case the battery is still discharging
too quickly, try the above again or do a re-install of your iPhone software via
the PC with iTunes. Then the problem should be gone.
Questions or remarks? Feel free to comment!

PS: Don’t forget to switch off the
Bluetooth connection after the new IOS 7.0.6. update. This also uses up extra
battery.
