Apps running in the background

Question

It seems to be if you have the app linked to a watch complication or you have it on your glances page, then those apps loads much faster.  I figure they are always running so the data can be displayed on the watch face or quickly at a glance.
So if you have every possible app on your glances page, then your battery life would drain much faster than if you have fewer apps.
I only have 3-4 apps on my glances page and I can easily get 20 hours of battery life, and this includes a 1 hour workout using GPS and HR monitoring.

Answer 1

Tbh, the biggest battery drain is your email push settings. I'd look at those before worrying about terminating background apps.
You can see everything that's running on your phone by using a "process monitor" app. I use one called "iStat". Unfortunately, iStat can only show you what's running, it can;t actually kill anything. It will definitely tell you which of the 1st party programs (browser, email, ipod) are running in the background.
If you actually want to kill one of these, the procedure is:
Open the app in question (e.g. launch the ipod app)
Hold the power/sleep button until the red slider appears.
Hold the sleep button for around 6 seconds (eventually the red slider will disappear and you will be returned to the home screen).
Whichever app was running (e.g. ipod) will now be forced to close.
** note: To close safari, you can simply close all the "tabs" down, and then exit. If you close safari when there are no tabs in use, it will completely shut down.
