Is there an app that shows what is using the battery? On my Droid it would actually show what was using the battery: Display, slacker, dolphin, live wallpapers, etc. On my X when I check battery usage the only thing it ever says is: display, cell standby, phone idle. It never shows live wallpaper, slacker, or anything else I run. I am wondering how much battery these other apps are using, particularly the live wallpaper. Any suggestions for a 3rd party app I can run for a couple days to see what is really using my battery.
I consider that my "About Phone ->battery Use" is not really accurate in my case. Can you advice me regarding another android battery usage monitor application ? I am interested in seeing the exact consumption (in percentage) of each service/application.
Have you found any app to monitor data usage app by app? I really need something to find out which app is transmitting, because since I installed Froyo, I'm having ridiculous amounts of data downloaded to the phone, but I don't know where it's all going.
When hitting battery usage, would the LWP show up under display? I loaded in a new LWP from the market and checked battery usage and display was off the chart % wise compared to my normal use. And that was with some pretty decent phone activity. I disabled the LWP to check, but does anyone know if it will show here? Or anywhere?
So I just switched to DroidMod 1.0 from SholesMod 2.0.5. Now when I check my battery usage it only shows Voice Calls, Display, Cell Standby, and Phone Idle, and thats it! It doesn't display anything else like it used to. Does anyone know why?
ps I wasn't sure whether to put it in the Root section or not, Mods feel free to move
My X recently (within the last week) started having extremely poor battery performance under the same usage conditions as the previous week (K-9 syncs every 15 min, maybe 2 texts per hour, 2-3 emails per hour, maybe 5 total minutes of phone use). After 4 hours, the battery would be at 20-30%
To make matters worse, most functions were extremely slow to respond (contact loading, test message loading, recent calls, bookmarks, any scrolling was choppy, etc.) The delay when trying the most basic things (opening the browser, making a call) was getting unbearable.
I started backtracking the changes in the last week. Although I started tinkering with Google's App Inventor over three weeks ago, that's where I focused. I uninstalled all App Inventor programs, including the Eyes-Free Text to Speech engine. This engine was recommended by Google to do things like read text messages in the Apps you create.
Still no luck.
I decided to investigate the battery use a little more. In Battery Manager, I found that "Android System" was using about 70% of my battery. I was typically used to seeing things like "display" at the top.
I have an app called Android System Info. This showed my CPU usage pegged at 100% (even after a reboot). It never got lower than 99%. The biggest CPU hog was "Android System" at 75-80%, consistently.
This App has a tab to view the log, and I noticed several recurring error messages in the log. They were occurring at the rate of about 180 times per second! The error? "Invalid TTS Engine" Well, the TTS is controlled by the "Android System". The "Android System" was constantly trying to load the uninstalled TTS engine.
I went into "Settings...Voice input and output", and, although the Eyes Free TTS engine wasn't available, the default TTS was not set. I checked the box to have the native TTS as the default, and checked the box for "Always use my settings".
Everything immediately went back to normal. CPU usage is now around 10-20%, and "Display" is back at the top of my battery hogging functions.
Battery life is back to over 10 hours, and the delays are gone.
I just got my droid x about 2 days ago, and I've gone through about 2 full cycles. So far I haven't been able to squeeze more than 6 hrs of use on it, so I installed spare parts to see if the GPS bug was affecting it.
Going through some usage information, I found that the "Android System" sensor usage was huge! Since 1hr 29min unplugged the Sensor has been on for 1hr 36min...weird.
Checking the total time since boot the sensor has been on 19 hrs. I have autobrightness turned off and I haven't come across any other posts that explain what uses the sensor.
how to get the battery usage per application.I want to implement battery usage per application in code. So I need idea how I should work to get this. I am not searching for app shows battery usage. I want to implement one such app.
12-1:30 "texting, downloading youtube videos and listing to music on droid live" dropped from 100% to 60% from 1:30-6:45 "listening to droid live but probably lost connection half way through the night" 60%-0%
i also have wifi and gps on all the time, settings for brightness is automatic. cpu set 550min to 880max. and have juicy defender free running. also tons of widgets "about 3 screens full of widgets. and lookout defender/set cpu/ nimbuzz/ battery status running in the notification bar. to me it looks like its fine, but what i noticed after really looking at the plot is the battery power drops 10% almost every 30 minutes during heavy use. and a hour between 10% drops and its almost on the dot to.
Does anyone know of an app that measures which apps use the most battery? I tried using various battery meters, including Battery History, BatteryLife, Battery Time, and others, but none of these seem to have this useful functionality.
I am having trouble finding class or API in android documentation which can help me get battery usage statistics per application. I have read PowerManager class and BatteryManager but they are of no use .Though I can find applications like PowerTutor that do give you battery usage statistics per application, so I think its technically possible?
I checked my battery usage and 33% is being used while Phone Idle and 36 while cell standby. Anyone know if this is normal or is my draining too much battery? BTW my Fiancee DL a Ping Pong app and played it once. I checked my battery to see what was using it, the ping pong app had drained 90%.
in reading thru the forums i notice that most users, when discussing their battery, are using some monitor which reveals percentage of battery juice remaining. i find the stock monitor in the status bar to be insufficient. what apps are you guys using that give you the best reflection of battery %/time remaining, indicate what's been using the battery, and most importantly do not eat up battery like a hog and make it not worth using?
With all of the questions and threads regarding battery usage, life and monitoring, I thought this might be a good time to share my thoughts of what has helped me *deal* with this issue.
I want to preface this by saying that:
-Yes, the stock battery supplied with our phones is probably inadequate. -Yes, having to buy a better battery after purchasing a "Tier One Phone" sucks. -Yes, usage is subjective and dynamic and one persons heavy usage is another persons light usage. -No, this will not address extremely short battery life (other problems are causing that) -No, this will not account for the phone seemingly giving a false 100% indication. -No, this will not help anything but your psyche
That said, I think we (myself included and maybe the most guilty) are putting too much emphasis on what our battery widgets and indicators are telling us. The blessing/curse of our phones is that they report battery life in 1% increments which is great for keeping accurate battery life information, but its not great for our sanity. Think about that logically for a moment!
Here is my experiment for anyone who obsesses over battery life but can make it through a day with no worries of their battery dying!
1) Next time you fully charge your battery, after you remove it from the charger, keep an eye on the widget as it drops down to between 95% - 90% and then take notice of your default battery indicator. It will still look fully charged! Do this for a day or two if you want!
2) When you are satisfied that what I'm telling you is reality, uninstall your battery monitoring widget or app and just go about your day as usual for about a week.
I am willing to bet that those of you like me, who actually have respectable battery life but still obsess over it, will not go back to what I call "percentile battery monitoring". Of course their will be exceptions as some people just need that number, but I really believe this may help some people get over their battery monitoring obsession!
i bought the full version of systempanel last night, because i installed setcpu and tasker over the weekend and started overclocking - i wanted to try the monitoring service and try to see if there was a drastic effect on my battery... well, the battery DEFINITELY seems to be draining faster than it did yesterday, and the phone seemed to be very choppy when switching between home screens. i disabled monitoring and it seems to be more responsive again.
I did some testing with the Navigator yesterday and I have to say it's absolutely awesome. I'm not sure if anyone has posted this, couldn't find any mention of it, but I want to share my battery usage experience with it as well as some other cool things I noticed.
Very cool battery saver: I used it for a 15-minute drive, keeping it only in the Notification Bar. When you are in the Navigation app, you can press the Home softkey to go back to your home screen. This keeps Navigator working in the background, but it is not drawing the maps and using the screen. You can press the Power button to put your phone to sleep, and the voice actually still talks to you and tells you when to turn. And even better, I started this trip with 76% battery and ended with 76% battery.
Now, the not-so-cool. I used it for a 30-minute drive, keeping the screen on and letting it show me the map the entire way. I started the drive with 54% battery ended with 34% battery. So definitely keep it on the charger if you are using it for a long drive. But another awesome thing I noticed. I made a phone call toward the end of my destination, just to see what would happen. I used the Home key to back out of the Navigator (but keeping it in the background, as I said above), then made my call as normal. The Navigator still gave me directions while I was on the phone. It came through the earpiece now, so the other person doesn't hear it. How freaking cool is that?
My Eris, just updated on Monday for the lock up from sleep Anyway, I am a low user of the phone and keep, wifi, Mobile data off unless I am using it I have noticed the last 2 days the battery life is improved. yesterday, phone on at 6am off at 11pm, 65% left, no data used, few Txt messages and about 45 min of phone calls Today so far, on at 6am, WIFI, Mobile data off, one 6min call and one txt, at 9am, still 100% battery. turned Mobile Data on at 9am now it is 11:50am and battery is still 100% my on time is 5:45, awake time is 8 min (2%) this is typical for me. I don't have email set to push, I refresh when I want it. I also use Advanced Task Manager. So maybe the issue that was fixed was also causing a battery drain and is fixed now?
Just spent 20 minutes searching for this to no avail, so sorry if answered elsewhere. I am rooted. I need a good battery app that will also read my extended battery. Maybe one that has two profiles, and accurately reads both. I'd also prefer percentages in all numbers, not just 10s, but not a deal breaker. Anything out there? The descriptions on the apps themselves are not very in-depth and don't want to keep installing and taking off.
The battery status is horrible. Why does it look like it's at 50% when at 30%? I downloaded an app that puts the percentage in the status bar, but it's at the top left in notifications. Is there an app that replaces the current icon with one with a percentage or, at least, is more accurate? I doubt there is. I didn't find anything on Marketplace or through search.
I manually updated my Eris the other night and I must say I am happy with the update, it has really helped with my battery. What I have done is installed Battery Indicator by Darshan Computing. This puts a battery percentage indicator in the notifications area. I have set the built in timer for an hour and when it goes off I make a note of the battery in form of a percentage. Here is what I have so far.
Hour/Percentage of Battery Remaining 1/98 2/85 3/82 4/80 5/77 6-70
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.
