General :: How The Apps Affect Battery Usage
Dec 11, 2012
how the Apps affect Battery usage. I'm using a Note 2 with the latest OS.
So, I wanted to know if the apps are still using battery power when I switch screens? When I press the center (home) button, it shows me thumbnail list of all the apps, areas I've been to or used. I can select and remove them from the list. I am wondering if they are still using battery power until I remove them from the list. If this does tend to use extra battery power, is there an app out there that will definitely turn off the app when I am not using it?
I just don't know how Android manages Memory/power. It just seems that I can watch my battery power decrease, even when it's not being used.

So I changed my DPI setting to 150 since in launcher pro I use 5 rows instead of 4 so it doesn't overlap etc. And wanted to ask if changing the DPI setting may affect the battery usage (recalculating screen) or CPU (making it slower) or the games will lag? etc.
Changed it back, I think was lagging and the text boxes were smaller not on the whole page. And the confirmations had green lines in the middle.
How I did it:
1. Root Explorer , mount R/W in system
2. Open in text editor.
3. Edit the build.prop line with ro.sf.lcd_density=150 and save the file
4. mount R/O and reboot
Still if someone knows something about the battery usage and cpu etc. So I know in future if I should play around with this one.

Just got my D2 yesterday after spending way too long with the Eris... so far I'm loving it, but I have one question: do everyone's phones seem to randomly open 10-20 apps in background at all times? These aren't even apps I use, like a Sudoku game I haven't tried once yet. I'm not too worried about it, since performance seems to be fine, but I'm wondering if this will affect battery life.

This is NOT a "my battery life sucks" thread, i'm just wondering what apps everyone uses to monitor their battery life and device usage.
I'm currently using:
Default Settings > Battery > Battery Use
Spare Parts
System Panel
Battery Graph

I noticed a few days ago Friday that my battery all of a sudden started draining faster; a lot faster. I did a FDR Tuesday night and through most of the day Thursday it was much better. Thursday evening i started reinstalling apps to test if it was actually better and noticed as soon as i did that the phone was never sleeping again. My up time and awake time were almost the same as soon as i reinstalled everything. So last night I uninstalled everything again except for swype. I'm going to watch it today but I'm not sure what to expect. Have you seen swype affect your battery life.

I'm trying to understand a few things about ROMs,the froyo upgrade from Verizon and battery charge speed.It's no secret the recent froyo update extended the time it takes to reach a full charge.Is this a function of the ROM they deployed,the kernel or something else?I hope I'm using the right terminology

Is there any device (phone or tablet) running Android 4.0.x that can display the native battery usage data via Settings --> Battery , instead of displaying "Battery usage data not available" ?
It is supposed to display a list of apps and what % of the battery they consumed.

Does it affect the battery if I constantly keep my phone plugged into my USB while at work? It's kind of warm right now, but I'm not worried b/c it's not overly hot. I just want to make sure it's ok. I got this phone Friday for my wife and myself and we both love it. My wife says she can't hardly put it down. I'm sitting at work streaming pandora while I work.

I've got a ton of apps, so I'm looking for an app drawer replacement that allows me to sort apps by frequency of use. I'm imagining a list view that will sort my most used apps to the top (I'm bad at remembering app names, so it always takes me a while to find something).
I'd prefer some sort of standalone app organizer, not a launcher replacement, since I like the launcher I'm currently using.

Have a brand new HTC One X+ (AT&T). Having an issue where after boot and sometimes all of the sudden during the day, the phone gets hot and battery level drops l like ton of bricks. Using Android Task Manager App and enabling monitor of system processes and selecting realtime monitor, I've traced the problems to "android.process.media". This appears to be something to do with Android scanning the device for media files (audio/video/etc) and creating some sort of database. I also usually see the "Music Enhancer" process which has to do with Beats Audio according to HTC (but I have Beats turned off.)
I've seen old threads of people with same problem and in some cases it had to do with a "corrupted" media file and they had to remove all media files and/or factory reset their device. I just spent an entire weekend customizing this device! Plus, how the heck do you prevent yourself from copying the corrupted file over if it was a corrupted mp3 or something?
I'm pretty sure my issue stems from the fact I used my media manager (Media Monkey) to sync over 2,800 audio files to the device. My collection is of high bitrate quality, about 16GB worth of music. I'm pretty sure this is what it is choking on. What I'm not sure of is if the Media Scan the Android device is performing is just a "normal check" for changes/addition/deletions to any of the media files. This of course would take a lot of time and CPU if it has to scan 2,800 files every reboot or periodically. It seems launching Google Play sometimes starts it too as I also sometimes see Google Play Service:Music or something like that (even though I don't stream any of my audio from Google Play.)

I'm wondering about apps that are a little more than battery power monitors. I'd like something that will show me the apps that are running and taking up the most memory and causing the biggest power drains on my phone.
Something that would log this so I could look it over during the week and get an overall view and make decisions on what to keep and what to erase.
I'm thinking something that would show me what apps I used, how long they were running, how much memory they took up, how much battery power was used, etc.
Is there such an app out there? I'm wanting to look at the differences between the free apps and paid apps to see if it makes a difference also.
I'm running a Sprint GN2 currently 4.1.2. I haven't gotten the update yet.

I migrated from Mororola RAZR (XT910) to Alcatel One Touch Idox X (6040D) on both phones I have the same applications, but on the Alcatel it happens again and again that out of nowhere suddenly Streaming media starts to download a huge amount of data, until I restart the phone.
-Google backup, location, photo sync is OFF
This behavior happens even if the Apps such as IMDB, YOUTUBE, POWERAMP are force closed. I used Watch dog 3G so My Data Manager, but both of them just show "streaming media" as the process eating the data. As Youtube was noted in System data consumption I could set there Background data limitation, which worked a little bit, but the issue continues, like some other application would try to take over YT misbehavior
Yesterday the phone "streamed" like this 6GB of data on WIFI and almost 700 MB on mobile, last month with XT910, I lasted with 700 MB mobile data for more than 2 weeks.

I have been disturbed by how much battery it seems to use while it's sleeping. After much poking around and reading and using various system/battery/monitor apps in a non-methodical manner, I think I found it. I noticed that a process called 'compass' at /system/bin/akmd was persistent in utilization on my phone. While it only ever showed like 1-6% cpu utilization, it seemed to be showing it constantly. I uninstalled a 'compass' app I had DL'd from the market, but that had no effect.
With some searching, I found some threads over at XDA that discussed this process misbehaving in some recent builds, although the conversations didn't seem to be about the EVO. Nonetheless, I decided to disable the auto screen orientation (Menu -> Settings -> Sound & Display -> Display Settings/Orientation = unchecked) and lo and behold, I'm not sure the phone even uses battery in standby now! (exageration for effect...)
Now, this will require more testing, but it seems to be at the root of *my* battery issues. And I'm thinking after reading at XDA that this could be a broad problem. I'm also hopeful though, that this could be a relatively easy software fix for HTC/Google. Especially because I don't particularly find disabling the screen rotating an acceptable long term solution... but one I can live with for now, if it makes the HUGE battery gains it seems like it might.

Soo running the froydvillain 1.4.4 tried different kernels. Would ask this on their IRC channel but I think they would lynch me :P The max stable I get is 748 was running it for like 10 mins :P (768 wont boot) Was running mostly 691 and now 614 . But dont know what will the difference in power consumption be. For example when playing with the phone and it will have to go to the 691 will it hold a lot less? Or its just a minor difference?

this thread directed at those that did not root or unlock their HTC desire but uses its original android.. before i go on, my standard usage is as follows, mostly sms using, a phone call or two, less than an hour of wifi browsing at night.. on android 2.1, my battery lasted roughly 2 days and a bit more.. after updating to android 2.2 via wifi through auto update on the phone. today was my third day after charging my phone to 100%.
its now almost 5pm, on my third day and my battery still has a whopping 40% of battery life left.. so just wondering whether anyone else have this miraculous boost of battery life with android 2.2 or not.

I'm wondering what the best charging strategy is to get the battery working at its best. Let it run down to almost empty then fully charge each time or just keep topping it up when I'm near power?

I was screwing around with battery usage today and here is what I found as the bottom line. Now this doesn't mean this is the same for you, but I'm sure you all know that. I changed nothing on the evo besides Gtalk automatically signing me in. (No skimping if you would) and I was at a golf club all day yesterday and had perfect signal strength. My EVO went 23hrs on one charge with decently heavy use. When I went back home (bad signal, 1 bar, no 3G) my phone's battery lasted just about 13hrs. Therefore I think TWS is one of the biggest battery culprits. Hence why if you complain to Sprint, they send you a free Air Ave like they did for me and many others.

I decided to do a little test with my Evo. Yesterday my battery drained out in 3 hrs at work with the Wifi off. Today I turned on my wifi at work and I got 7 hrs before recharging the battery. Weird I thought if Wifi is on it would drain the battery faster.

I am using the Y5 app and my phone connects to my router when I am home. I just checked the battery usage and Wifi was showing 22%. My up time is right around 27 hours. Does 22% sound a little high or is that good?
