Android :: Power Consumption - Profiling Of Application

Aug 20, 2010

I'm the developer of PowerTutor, a power profiling tool for the system. This tool profiles the system power consumption and decomposes power consumption on hardware components (e.g. LCD, Wi-Fi, CPU and etc.). It also assigns power consumption to individual application as the application is running alone in the system. In this way, it could potentially help developers to profile the app and detect energy inefficiency usage behavior in the application.

More details could be found at http://powertutor.org.

Note that PowerTutor is free to download and no advertisement is embedded. I'm posting this here to so that the Android community can be aware of it. Any one who cares about power consumption of their applications will find it useful.

General :: How To Debug Android-System Power Consumption

May 27, 2012

find out which app is draining my battery and if it's really necessary. couldn't find any information on the SDK pages.My Phone seems to be very often Awake while in standby. I can't understand why it has to wake up that often. Am I right, that this "Awake" means, that the cpu is running (not in sleep mode)?

Is there any way to log which software is waking the device up?

General :: Power Consumption Of USB Device In OTG Mode

Jul 19, 2012

I want to develop a peripheral device to connect to an android phone via USB OTG. The OTG specs [1] says: "A Targeted Host shall provide sufficient power to each peripheral on its TPL in at least one supported configuration".
Where do I find those TPL ("Targeted Peripheral List") lists? I searched at Sony Ericsson (because I have a Xperia Mini) and Samsung (as a different manufacturer) but with no luck. Is this an android related list?

On github I found a code fragement [2] from DooMLoRD. It mentions a OTG whitelist. But it seems to be something like a skeleton.

I do this research because I want to use the peripheral device in high power mode with about 300 mA. I thought I could compare the TPL with devices that also need 300 mA.

HTC Incredible :: Way To Downgrade Radio / Turn Down Power Consumption?

Sep 9, 2010

seems like anything using 3g drains my battery. slacker player saps 30% of a 2600mah battery in a single hour. If I were to be conservative, it would be 25% of a 2200mah, accounting for other parts of the phone and possibly a low quality battery. Even then, that's horrible. It didn't used to be this bad. And now I suspect it's a combination of a new radio update that boosts signal by consuming more power, and the fact that 3g coverage is weak where I'm at (though it worked good enough before the update). So if there's any way to downgrade radio without losing froyo or other phone functionality, or directly influence power consumption of the 3g radio, please let me know.

Samsung EPIC 4G :: Huge Power Consumption When Watch Youtube Video?

Sep 8, 2010

I was using the Google navigation on 3G network with the phone connected to a 500mA car charger. After 1hr, the battery dropped 20%. Anyone knows if a 1000mA car if enough?? Tonight, I was watching a Youtube HD video on 4G network (2/3 bars on 4G) with the phone connected to a 1000mA USB wall charger. After 10min, the battery dropped 2%...Well, even 1000mA cannot compensate the consumption of the battery. The power consumption of this phone is ridiculous. Something must be wrong with the system/circuit design.

Android :: Impact On Existing Connections When Switch Between 3g / Wifi?

Aug 18, 2010

Assume that, I have a TCP connection that doing heavy data transmitting on my 3G network; and I walked home, Android switch to my home Wifi automatically. Now what happen to the existing connection? is it simply disconnect? or it will keep going, only new connections will use wifi? In addition, what if I walk away from home, wifi lost signal and switch to 3g? It should be safe to guess the connection is dropped. For my application, do I need to handle the reconnection or there is a auto fall back solution.

HTC Desire :: Dropped From 3 Cm - Phone Instantly Off On Impact

May 4, 2010

I am trying to investigate why I seem to come to my phone (without dropping it) and it is sometimes off. I remembered that I had a couple of small drops before, the kind of drop that would not have made any previous phone I've had even skip a beat. So I did a test and dropped it on purpose.

3cm drop.
Phone dropped completely flat on it's back so it landed flat.
Phone in silicone/gel tight fitting case.
Glass table.
Screen on when dropped.

Result? Phone instantly off on impact. To me, I find this way too delicate in comparison to phones I've owned. Now, this is my first big screen smartphone, but not my first smartphone. My last was the Nokia E71 which was very very well built. Evidently, it was even better built than I thought.

Am I being harsh/naive and this is normal, or do I have a delicate unit?

Android :: Facebook App - Data Consumption

Oct 22, 2009

I like the new Facebook app. However, it is currently consuming 12.76 MB (this is the data amount) of valuable space on my G1. Unlike many other apps, there is not a Clear Data or Clear Cache button available to recover this space. Anyone else experiencing this? I have deleted apps I seldom use and find it increasingly difficult to keep my G1 from slowing down due to free space 20 MB and lower. I am thinking of deleting the app and reinstalling.

Samsung Behold 2 :: Portable Power - Car/ac Charger Or A Stand Alone Power Pack

Jan 5, 2010

Has anyone had any luck with aftermarket power supply's. I'd like a car/ac charger or a stand alone power pack. I usually use my DEXIM. but it does not work with the Behold 2. I've tried a car charger/battery unit by Wireless Gear that said it was compatible with all Samsung phones, it came with 5 power tips and a USB outlet that still would not work, even using the OEM USB cable. Any suggestions would be appreciated. I will go with OEM Samsung if necessary, but there selection is limited.

Android :: Track Memory Consumption (Bitmaps)?

Mar 26, 2009

How can one track memory consumption in Android? The Android "Heap" view in Eclipse and java.lang.Runtime methods seem failing for my purpose. I tried to figure out how much memory my app consumes in order to make decisions for future directions. Most of the memory goes into Bitmap objects. Just to test memory consumption I created huge bitmaps in a Loop and logged the java.lang.Runtime memory values: created bitmap (610k free, 2371k total, 16384k max) created bitmap (615k free, 2371k total, 16384k max) created bitmap (615k free, 2371k total, 16384k max) created bitmap (615k free, 2371k total, 16384k max)

Nothing seems to hapen, but on the fifth Bitmap: java.lang.OutOfMemoryError: bitmap size exceeds VM budget at android.graphics.Bitmap.nativeCreate(Native Method) at android.graphics.Bitmap.createBitmap(Bitmap.java:343) at de.greenrobot.colorball.GameView.init(GameView.java:86)

This seems confusing at first. Is java.lang.Runtime the right place to check application memory stats in Android at all? Are Bitmaps allocated outside the app's heap? How can I track it?

Android :: Designing Service For Consumption On Multiple Mobile Platforms

Apr 27, 2010

I am building and designing a (mostly) read-only interface to some data. I'll be uing ASP.NET MVC to build a psudo-restful API. I'm wondering if anyone can provide some resources for building full-client applications for various mobile platforms, iPhone, Android, Blackberry, Windows Mobile, etc. I'm thinking that serving up XML data is going to be the most simple and universal, but parsing XML in objective-C for example doesn't sound like fun to me, but maybe there are some good libaries out there to help ease this task?

In other words, what formt will be the quickest to implement on the client side? Are there any JSON parsrs for iPhone or Android? I know there are .NET JSON parsers, but not sure about other platforms -- is ther another format that might better? Or should I stick with pure XML and deal with it on each platform differently?

Android :: Google Apps And Google Accounts Merging - Android Impact?

Jul 5, 2010

According to: What's changing : About the conversion - Accounts Help, Google will be merging Apps Accounts and regular accounts. Anyone know how this might impact Android? I currently use an Apps account and a regular account both with a myname@mydomain.com login. Once I got the hang of which services used apps vs, regular vs. both (and how to tell which one I was using for what), this seems to work OK on the desktop. But on Android certain services like Checkout seem to only work with @gmail.com accounts. I wonder if this change will make things more or less confusing on Android.
