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.
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 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?
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"
Here is a couple screens from my EVO. When it warns you to plug in the phone it also has a button to check usage that is built into the phone. Wish somone could build an app directly to this. As the battery was draining (almost dead) I left this screen up (waiting for it to die) total of 13hrs and 20+ min. It does not use any battery to check this. Look at how long it has been unplugged. The BT, Sprint Nav and Beautiful widgets never get killed by my task killer because these are a must for my job. I am a Professional Driver of 21 years and these are needed.
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.
My battery almost died after 6hrs unplugged, made 1 phone call, checked FB and email once. What happened? I have the incrediable, I had a full charge when I left at 7am, around 1 something my phone almost died. I had nothing running in the background
An hour after my G1 phone was fully charged, the "Battery Usage" showed me that my game had used 20% of the battery usage. Except, I never ran my game (I had run the game before starting the charge). I checked TasKiller, and it didn't list my game as running (my game also doesn't run any services). When I clicked on the details of the battery usage for my game, it didn't list anything under the "Use details" section. Is it possible to use battery, but not have anything listed under the "Use details" section?
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 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.
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.
I am running the 0.3 rom.. and there is no battery usage under about phone.. its there on the droid am i missing something? Also to make it more stange when you get down to 15% it gives my a low battery warning i can either say yes or view battery usage.. but cant seem to find it anywhere in the menus.
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 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'm watching the world cup on the ole droid incredible thought the univision website using skyfire and I know it's taking up lots of battery. I can use wifi or 3g where I am. does using the 3g antenna take up more or less battery than the wifi antenna when watching streaming video?
Sorry if this was already asked, but I did search.wifi is off, but when I check what is using the battery, it shows wifi using 2%. Is that normal? Why is wifi still using the battery? my phone: HTC Incredible Rooted Skyraider 2.5.2 vanilla Hydra stock speed undervolt kernel
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?
What is the best way to determine what is using my battery? I know I can go to Settings | About phone | Battery | Battery Use and see usage to a certain extent. But what if I want something more granular? Usually, the largest percentage of usage is by the Android System, is there a way to see which components may be using the most?
I propose that we all post our battery life graph like the one I am about to post below. This way we can look at these claims in scrutiny, and perhaps figure out why it is that some people's Evos seem to last longer than others. Here is a graph of my Evo's Battery Charge over 1 day:
Wake up at 7:30am to disconnect the charger, listen to Pandora on the car to work until I arrive at 8am. Idles until lunch time at 12pm. Use the Evo to read up on some news at lunch until 1:30pm. Listen to Pandora while working until 5pm. Drive home while listening to Pandora in the car. Battery starts giving warning indications while driving, and phone dies when I get home at 6pm. Very usual day, and matches what the battery charge graph shows. The top apps of the day are:
System Processes contains mediaserver (2.4% due to Pandora), akmd (0.3% accelerometer polling), and everything else is <0.1%. As you can see I barely used my phone during the day for anything but Pandora. So based on my data, I'd say that the normal battery life for the Evo is under 10 hours. My settings are: no 4g, no wifi, no bluetooth, yes gps, yes bckgrnd data, auto brightness, no live wallpaper, yes taskmanager (ATK, set to "safe" setting. Will probably get rid of this..), no friend stream, no flickr.
I'd love to see other people post up their Battery Usage graphs as well. The App used is "SystemPanel App / Task Manager", available for free in the market. Go into Settings and allow it to Monitor. The screenshots were made by ShootMe, also available in the market.
