How does Battery Sense work?

[SoullessOnyx]

Hey, so how does Battery Sense work? Does it just tell me what app is using most battery life, is that it? Does it let you completely turn the app off or does it just tell you this app is using most battery life?

Yes it tells u which apps are using more battery life.so that u can disable or u can reduce the usage of that apps

So currently on Windows Phone 8 we can disable apps in the background? Because I have all apps disabled and that's not good enough, will this be more in depth?

 

[Nikhilarthan]

No there wont be any more in depth...!!!

Great... Well if my 920's battery life is stupidly crap now.. Then my phone is going to love 8.1. =(

My 920 can last, uncharged, for a day and a half, maybe even 2 days (but I like playing games...). What is "stupidly crap"?

If you have an app that drains you even if it's disabled in the background, battery sense can detect that app for you.
If you have such apps in your system, just uninstall them, so yes, your 920 and you will loove 8.1.

Although the developer tools allow developers to profile power usage on an app today, hopefully Battery Sense will create a large pushback for devs who don't use that to optimize app power, or to help identify unknown bugs.

The battery life on my 920 has been horrible since I upgraded to 8.1. I'm not sure what's causing it though. Battery Sense shows me that the Phone and Cortana use up the most power, but it's crazy how hot it's getting and how much battery is being drained. Any suggestions or thoughts?

Same here, Cortana seems to be a non-stop power draining succubus ***** of an assistant lol.

Have noticed substantially more battery drain on my 1520 too since update.

Hahahah.


Have any of you considered your battery is worse after 8.1 because you can't take your hands off of it?

Edit:

So I'm really pissed you can't put a shortcut for Battery Saver in the activity center. That's a bogus decision. I certainly turn that off and on more often than rotation lock or anything else in that menu.

I noticed that a significant amount of apps had battery usage set to "allowed" in battery sense. I just went through and changed all of them except a couple to not allowed. Cortana of note is "always allowed".
I do miss the ability to easily see which app had turned on background tasks in WP8. All of the Bing apps now seem to turn on background tasks everytime they are opened which is BS imo.
Anyways, has anyone else found a way to disable background tasks? Is doing it in battery sense the same as the old way?

I found all the background apps I disabled was re-enabled after 8.1. I have manually disable them again. Also, Nokia Drive+ is now consistently #1 battery killer on two of my phones (it is updated and now available on my HTC 8x).

Hey Talderon

Can you provide any insight as to what those colored bars actually mean? What exactly are they displaying? It's nice and all, but so far it seems very vague to me:

• Is it just visualizing the amount of time an app was in the foreground (possibly doing nothing at all), or is it more sophisticated?
• If I let an app run for one minute using one core, will it show less battery usage than if the same app ran for one minute using two cores?
• Does the visualization take into account all the major hardware (particularly the radios), or is it focused only on CPU time (or possibly only wall clock time)?
• If an app runs primarily in the background with the display turned off, will it show different battery usage from the scenario with the same app running in the foreground with the display turned on?
• Are results comparable between devices, or are the results only valid relative to other apps on the same device?
• etc, etc, etc

Any ideas? Resources? Would be much appreciated!

Battery Saver, sweep right, scroll to the very bottom and touch "show all apps".
