Motorola Droid X :: Android System Sensor Usage - Possible Battery Hog
Aug 5, 2010
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.
I'm having problems with my Droid Incredible battery not lasting a full day; even when I don't think I'm doing a lot. Maybe its the K9 Mail applications or my stock monitor, or some other application that is using a lot of power.
I got the System Panel application to help, but it doesn't see to give me a view of what application is using up the power.
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?
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.
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.
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.
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.
My home icon is way less responsive than the back icon which seems to be perfectly normal. Sometimes I have to "press" the home icon twice to get the "buzz" and have it move the screen. However the back icon works 99% of the time on the first press. IS there any adjustment I can make or should I bring the phone back. I have had it now for 2 weeks.
I see that a lot of folks recommend "Spare Parts" as a app to monitor system usage. Are there any other apps out there that do the same thing? The main reason i ask is because Spare Parts doesn't seem to have the greatest reviews so i have been debating on installing it.
I main thing i want to be able to do is see what is using my battery power.
My Son and I both have EVOs - his battery drains about twice as fast as mine. His application list is here: Kevdog83's Apps on the PC36100 When he checks "Battery Use", Android System is consistently 85-90% of usage, while Cell Standby and Phone Idle are typically the two biggest items for my usage. What runs under the umbrella of "Android System" that may be killing his battery?
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?
I am writing a program and I am able to get the light sensor value and current battery level, but only the light value changes and when the battery level changes. Is there a way to get these two values anytime? Like when a user runs my program, I would like to grab the current values right away instead of having to wait for them to change.
I have a HTC Hero here, and when I tried to get the list of available sensors on the device by calling ((SensorManager) getSystemService (Context.SENSOR_SERVICE)) .getSensorList(Sensor.TYPE_ALL); I get only the following sensors: D/SensorManager( 6302): found sensor: BMA150 3-axis Accelerometer, handle=0 D/SensorManager( 6302): found sensor: AK8973 3-axis Magnetic field sensor, handle=1 D/SensorManager( 6302): found sensor: AK8973 Orientation sensor, handle=2 D/SensorManager( 6302): found sensor: AK8973 Temperature sensor, handle=3 According to the specs, there should be a light and a proximity sensor on the Hero, and I've seen it in action (the automatic screen brightness adjustment) - so at least the ambient light sensor is definitely there. My question is then, why doesn't the getSensorList return for me the light and the proximity sensors?
Does anyone know the difference between the orientation sensor and magnetic field sensor on Android?Since I've read that magnetometer is synonymous with digital compass I'm a little bit confused. What are they really?
Is there a way that a ROM could disable the proximity sensor during a call? I have a huge problem where I constantly hang up on people (usually my girlfriend) and that doesn't go very well . If its possible for the end buttonor volume button to wake the screen instead of the proximity, that would save me a lot of hassle. Is this doable, either standalone or through a rom setting?
I have been having this issue for quite some time, but just figures it was a bug in one of the BB roms I was using. Well, since then I have been through about 10 different versions of bugless beast, droid mod, and several others. My issue seems to be that when I make a phone call and put the phone next to my head, although the screen turns off, the touch is still activated.I will be in a call and I will feel the phone vibrate against my head. I usually hit the pound of star key on the phone, and as soon as buttons are pressed in a call, it seems to mute my voice to the person on the other side of the call. I have to remove the phone from my face, wait for the sensor to realize i moved my face, and have to press the backspace button till all the random characters are deleted at which point the person on the other side can hear me again. This happens to me on about 80% of my calls, and is by far the most frustrating issue I have had. Do you think I should re-install stock and bring it in? btw, I posted this in root sub-forum cause I am rooted, and wasn't sure if it was just a rom issue.
I've read through the deluge of threads that have sprung up since Friday's Droid release. However, I have only seen this issue listed within longer conversations about frustrations. I wouldn't call this a frustration as much as I would a quirkiness of the Moto Droid that I'm hoping some similarly-annoyed person out there has developed an app to overcome this.
The issue is with the screen lock and the auto-dimming on the phone. The first issue with the lock screen is not a device-specific issue as far as I can tell, but it is insanely annoying not to have a lock timeout setting within the OS. I should not have to unlock my phone every single time the screen dims from the timeout setting. Every other phone I've ever owned that has a screen lock does not have this limitation and, if someone were to mention that the iPhone has the same issue, I would point out that they suck.
As for the other issue, and the far worse one, how in the world is the proximity sensor when on a call so damn finicky!? I have read this complaint multiple times on various forums, but no concise list of solutions. The screen goes black when you have the phone to your ear, but when you move it away from your ear, the screen should *consistently* re-light so the user can have access to the keypad, etc.. This is not working at all as I would expect. I did find an app in the marketplace that allows you to set the screen timeouts by application, but if I set it to not timeout on the phone app, the screen will stay lit when I have the phone to my ear, which would defeat the whole purpose.
This seems like a huge bug to have missed in all the testing that occurred before releasing the phone, especially for such a basic feature. I expect customers to go nuts on Verizon for this one (my fiance is far from a technical user and has the Droid and has yelled at me to "fix it" referring to this problem..
i bought a mtk6577 clone s3. My problem is sometimes i rebooted phone, after opening proximity and light sensor doesn't work. screen don't turn off in call and doesn't call the person displayed on screen when i take ear. And battery drains too much. (example: when proximity and light sensor works with %90 battery, when it doesn't work after reboot plummets to %50).Another issue is when i reboot phone, boot animation doesn't show when proximity and light sensors don't work.
How can i get battery usage by application in android.I need to know % of battery spent by application.It's possible using SDK?The information that i need, using an android device it's on "Settings>About phone>Battery use"
