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 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 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?
View 3 Replies View RelatedBattery was at 24%. Talked for 10 Minutes. Now 18%. Really? 6 %. By that rate you can get 166.6 minutes of talk time. Does this sound right? No apps were running in the backround.
View 3 Replies View RelatedWhich is pretty cool because it puts a small icon in the top left corner of % remaining. But it does not tell me statistics - like what is using it the most, etc. I would really like an app that tells me the estimated time remaining on the battery.

View 35 Replies View RelatedNew DINC owner here, I am somewhat questing if my battery is anygood on my new phone. I unplugged my phone with a 100% charge and the green light on. I made one 4 minute phone call and viewed 4 emails and in that 10 minutes my battery went from 100% to 90%.
Stats are:
Unplugged for 10m 22s
android system 92%
voice calls 4%
cell standby 2%
WiFi 2%
Just viewing the battery use screen brought my phone down to 88%. Is this draining to fast? I also noticed last night at work I walked in with a 100% charge, I played around online a good amount and looked at some apps. Within an hour my battery life was down to about 60%. I realize these phones use a lot of battery but this one seems to be losing it's charge in a real hurry, my Blackberry was no where near this bad.
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%.
View 3 Replies View RelatedWhat's the best way to determine why all of a sudden my battery is losing it's charge more quickly than normal? I checked battery usage in settings and everything seems reasonable. I can't think of a newly installed app that might be causing it. (HTC Rezound, ICS) ADR6425LVW

View 3 Replies View RelatedThe only recent change has been the Facebook update and an AK Notepad update...
It's the Facebook update isn't it?
Battery life down to 2-3 hours with little to no use.
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.

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?
View 10 Replies View Relatedthis 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?
View 3 Replies View RelatedI 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.
View 5 Replies View RelatedI 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.

View 1 Replies View RelatedIs 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.
Can every post their battery usage of the calender, My calender is taking up around 70% of my battery and i barely have any apps installed. It is making the lifespan of a charge a nightmare.
View 9 Replies View RelatedI 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.
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?
View 2 Replies View RelatedIs 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.
View 4 Replies View RelatedI've been searching all over this forum as well as the internet on how people are using their HERO and the battery performance they're getting out of it. I've seen answers from 9 hrs with heavy usage to 36 hours with minimual usage. That's about all the detail I've been able to find. (Maybe I'm just not good at searching?)With that, I decided to do a little tracking of my own. I logged my usage and battery performance over a 27 hour period and thought I'd share it with the community. Not sure if this is even helpful but maybe it'll provide some sort of baseline for others to compare against.I recorded the battery level in % based on the stock battery meter, the time I recorded the battery level and any activity that occured between the current time and the previous time recording. For example, between 7:00AM and 10:19AM the battery dropped by 10% and I had received 2 emails, 2 calendar reminders went off and I had surfed the web for about 10 minutes.
View 3 Replies View RelatedHowever, this simply has not been my experience at all, I get a couple of days out of my SGS whereas some others report only getting a day.
I just thought it would be interesting for us to post in here how much battery life we are getting for the amount of use we put the phone to.
There must be some sort of pattern.
My usage:
anywhere between 10 - 30 texts per day.
Several emails - sending and recieving.
a few phonecalls.
30 Minutes of gaming.
Twitter.
Live wallpaper running.
BBC News widget running and Weatherbug widget running.
I also listen to some music but this varies day by day.
3G and HSPDA are left on constantly as is my wireless.
GPS is turned off.
Thats my usage and i get at least a day and a half. Would be interesting to compare...
When my SD card is mounted in my Magic, the CPU usage is very high (90%+), the battery is very warm (34 degrees +) and it drains the battery very quickly (dead in 10 hrs with very min use).
When the SD card is unmounted or removed, the CPU usage drops to 10% or below, the phone is cool and the battery lasts very long.
Does anyone know the reason behind this and how it can be resolved?
I've reformatted the SD card and removed some of the media files not supported by my Magic but still have this issue.
