[Q] Which app drains the most battery?

---

So i have been using my mozart for 2 years now, and i have probably ...200 apps by now. I install whatever

And it's obvious that this is causing a huge battery drain on my battery

on 3G i can probably only last 6 hours (without much usage)
on wifi 10 hours
If i continuously use it (web, game, social), probably 3 hours or less

So i understand i need to delete some apps but which app is draining the most amount of battery?

Location services are a BIG drain for me but lol at your background services and disable one at a time to find out for you. Apps don't drain unless they are active otherwise.

The single largest drain that apps have on battery life is advertisements. Wait, display might be first and ads 2nd.

This is why the paid versions of some games are preferable to the free versions. The free, ad-supported versions are battery hogs.

I already turned off all background services... didnt help lol

Something must be running background without my understanding

Lol my brothers trophy (which he is not using now), i reset it and turned off most features (3G wifi GPS) and it can last a whole week without charge....
Even with 3G or wifi turned on, it still does very good with a fresh reset
If only my phone can run that much as well!

If you have the app "super battery drainer" that may be the cause

Are you sure?

Are you sure that your interpretation of the problem is correct? Maybe your now 2-year old battery just does not have the original capacity anymore, and that's the main reason you do not get the same run times as earlier?

I have 2 batteries, I don't use the other one very much. But when I do the result is the same.

Unlike Android and WinMo, WP7 does not generally allow apps to run in the background. Those that do are under very strict limitations, intended to shield battery life.

You can see the list of apps that are able to do anything in the background at Settings -> Applications (pivot) -> Background Tasks. Unless an app is marked as "on", it won't run in the background. If you click Advanced, you'll also be able to see a list of apps that can run in the background under specific circumstances - for example, media apps may run in the background to play media, but if you stop the media playback or switch to another media source, the app will stop too.

That said, my HD7 is about as old as your Trophy, and is also losing battery life. I suspect a lot of it really is just due to the age of the battery, but some of the fancy new apps like LockWidgets2 are also huge battery hogs.
