Hi,
Anyone used PowerTutor to measure what's been using the battery?
You can find the app here:
http://www.appbrain.com/app/edu.umich.PowerTutor
Post your top battery drainers, and if you're using Eclair/Froyo please.
I tried it but deleted it after 1 day. Over a night my battery dropped from 80% to zero because of the app.
There is a battery monitor in android if no app appears it might be because their consumption is too low (I had only one that appeared it was an app to do RPD connections)
the android battery monitor doesn't seem as thorough I guess.

It may be possible that PowerTutor played a part in using your battery. Depending on your type of phone the PowerTutor profiling service takes between 3-15% of your phone's CPU, though we're always trying to reduce this.
Now as far as PowerTutor draining your battery from 80% to zero goes, perhaps what you should really be asking yourself is what is keeping your phone from sleeping during this time? PowerTutor won't (and indeed doesn't have permission to) do this.

So the built in app monitor is a bit simplistic. The source code is publicly available and I encourage you to take a look android.git.kernel.org/?p=platform/packages/apps/Settings.git;a=blob_plain;f=src/com/android/settings/fuelgauge/PowerUsageSummary.java;hb=HEAD. The built in monitor is only useful to calculate very rough relative power consumption between apps. PowerTutor uses accurate models of the phone's hardware, offers absolute power figures, displays recent power history charts, and offers a log for later inspection.
As for me, I run PowerTutor all the time and never have any problem with it draining the battery. To answer the original poster's question my greatest consumers come from a crossword app, google's music player (in a future release it will be possible to see what apps are using audio with some tinkering), solitaire, and then the browser. However most of the energy for these apps (except the music player) comes from the OLED screen.
I have been working on a website where some of the data collected through PowerTutor may be made available. This would display some basic power profile information for popular apps and perhaps some other usage characteristics. I've been a little busy recently but hopefully we can get this out sometime in the next couple weeks.
I havent used PowerTutor for some time, so I may be missing recent improvements. But from my experience I agree that it is a a serious batery drainer...
I don't use my mobile phone when at work. And normally it drains from full to 98~97% from 7H30, when I leave home and unplug it from charger, to 13H00 when I leave my work place to lunch. With BateryTutor the battery drained to +/- 80% in the same period. Tested it 2 or 3 times, always the same result.
I am giving it a try. It looks very informative and functional. I don't think it is to be constantly used, instead it would be more useful to have it running for a couple of days and see what is draining battery and tweak your phone accordingly.
Something that got my attention is that there is a android process called "download manager" that constantly drains 400mW. What is this? Can I somehow stop it? I am not downloading anything.
Thread moved to themes/apps section
Is anybody aware of any similar programs like Powertutor which gives similar detailed information?
I suspect Powertutor doesn't give correct information for the Samsung Galaxy S (it was developped for HTC G1/G2 and Google Nexus One).
According to Powertutor these 2 processes eat a lot of juice:
50% => Android Download Manager which translates to android.media process (from Powertutor logfile) <= I suspect this is incorrectly reported by Powertutor
10 - 15% => Samsung Power Monitor widget which translates to com.sec.android.app.controlpanel (from Powertutor logfile)
A program like Powertutor is clearly not meant to be running all the time but is very usefull in identifying processes which take above average power.
More information on Powertutor's working and energy-models can be found here:
http://www.google.com/url?sa=t&sour...sg=AFQjCNGwU_2TaxWE8TcwqHQLbfmU9A67AA&cad=rja
I strongly suspect incorrect readings for our Galaxy S...
Again I raise my question: anybody aware of a similar tool?
Please, info about an application like PowerTutor for our Galaxy S!!
Latest version of Powertutor (1.3.1) works a lot better now with my Galaxy S. The fact I upgraded to Froyo may be of influence.
It least Powertutor doesn't report 1 process (Android download manager) to consume all energy anymore!

The closest thing I have come across is BetterBatteryStats http://forum.xda-developers.com/showthread.php?t=1179809. It lets you know about wakelock drains and gives fairly accurate reading of processes and alarms using battery since the device is unplugged. I still want another Power tutor -like app though.
Hi
Like the title said, how can we see it? i am having a drainage issue (more than 40% drain in 8h on standby!)
I tried using Current Widget but it shows no data on my galaxy nexus. Also, i used Battery monitor widget (free edition from the market) but the numbers showed on standby (No auto sync, no wifi) are way too high ( around 100 mA!) is it normal? My old HTC desire will only display 4-6 mA! does the widget work properly on the galaxy nexus?
My phone has a stock rom, no apps installed (except for Titanium backup and the widget).
I looked at the battery stats, and there is no awake time, nothing..
Any help?
I have the same problems. CurrentWidget doesn't show widget in the widget list Battery Monitor Widget shows unusually high current (sometime 1000+ mah). I wonder if this phone supports reading current properly. Any solution?

Are you rebooting after widget install ? Sometimes you have to for them to show in the app drawer
Sent from my Galaxy Nexus using xda premium
Current Widget is showed in the widget list but it reports no data.. I checked the path sys/class/power_supply/battery/ and the "current_now" script is not present.. Maybe that's why there is no reading for the current mA in the Gnex?
hy guys i have a problem with this widget it shows correctly temerature mV percentage but when i switch to the consumption of mA it shows no data! in every rom i tried it will shows the same thing anyone can help me?
some screenshot
Have the same Problem
The Galaxy Nexus doesn't monitor this parameter, so the widget has no data to draw from. It was very frustrating to learn when we were trying to verify the force fast AC charging mode. Sorry.
Why is it showing "unkown(ac)" and followed by "Plugged In(ac)" during last few percents(93%~99%) when in charging, i noticed that the screen will be turned on for few seconds when the this was happening, and this happens so often(about 80% of the time).
---------------------------------------------------------------------------------------------------------
The app i am using to monitor the battery is called "BatteryBot Pro ". I have contacted the developer of this app, here is what he replied to me in the email:
The phone is reporting "Unknown status" rather than "charging", "fully charged", or "discharging". I don't know why, but the best the app
can do is show you what the phone reports. Some devices show "Unknown" for a split second during transition periods. It's probably brief enough that you only see it in the logs. I recommend setting up the filter to know show "Unknown" events in
the history.
----------------------------------------------------------------------------------------------------------------
I have T-mobile Samsung galaxy s4 and using OEM wireless charger pad and OEM back cover, and running the latest and original rom.
Has anyone ever notices the similar problem?
Now that the official build is out we can start monitoring how the battery is behaving.
Personally since the first Beta I was amazed with battery life, especially for an early stage software. Refinements has been going and I can get outstandinh results that weren't possible before.
I'll start with few screenshot and eventually update my experience.
Here's some details:
My device is Note 10+ SM-N975F (Exynos) 512GB build version BSL7 .
Brightness is set to auto, poor/average cellular signal strenght, always on WQHD+ and only battery saver options are the ones from Samsung with not so many tweaks in the settings. Most usage on wi-fi but 4G+ for a discrete 20% of the time. I never close apps in the background. Some screenshots present some abnormality due to Adguard filtering my internet traffic, I have local VPN always on. AOD was off the whole time since I setted Bixby Routines to turn it on only when charging. Sync was turned on all the time, GPS always on too, Bluetooth used for about 1 hour with Galaxy Buds. One Gmail e-mail in push. I have over 200 apps installed excluding system ones. My DPI is set to 598, my launcher is nova, I theme with HEX Installer, use One Hand Operations+, Whatsapp always syncing with my laptop.
Digital wellbeing shows about 70 unlocks and 220 notifications, inaccurate data but roughly exact since it counts some of the ones from the previous charge in the previous day.
To monitor my battery I use Gsam battery Pro, the Galaxy Lab "Battery Tracker" plugin and the stock battery monitor on Device Care.
Since the charge lasted more than 24 hours, Battery Tracker (Galaxy Labs) doesn't show the beginning of the discharge curve in the final screenshot so I attached one I made when I was at 40%. Remember Adguard battery consumption is miscalculated by android system, the Adguard app tells me it consumed 1.5% in the last 24 hours.
Feel free to upload your results and details let me know if you want further informations on my setup
