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.

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 :: Battery Consumption Is More At Boot Up Of Device

Nov 20, 2013

I had made changes in S/W as suggested in post : [URL] .....

The device I am working is also having wake up lag about 2 sec.It varies from 1.2sec,0.8sec,1.8sec..etc. I implemented the new wake log to prevent the phone from deep sleep as you have mentioned. Now the time required for wake up from deep sleep is reduced to 0.8s and its quite consistent. Although I have to yet check for battery consumption during deep sleep.

However I have found that now when the phone is reset the battery consumption is more during the power up of the phone. For Ex. from 36% before power up and 24% after powerup.

Checked with another device and its only taking 3% for boot up.

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.

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.

HTC Hero :: Large Battery Consumption In Airplane Mode

Dec 3, 2009

My non-branded GSM hero eats battery. So I decided to check some things out. These numbers are starting from 100% battery, and after a reboot - the only thing I open is settings to check the battery level, and then I lock it and leave it for 6 hours. In all cases the final awake time is low, less than 15% (because I'm doing nothing with it). Full data-sync mode - gmail sync, twitter, etc - about 10% battery use per hour. Retro mode - GSM only, data switched off - 6 % per hour. Airplane mode - 3.5% per hour - WTF?? (Awake time ~1%) Why is battery consumed when it's doing sod all?

General :: Samsung Galaxy S2 Power Button Not Working In Recovery Mode?

Oct 13, 2013

my galaxy s2,it is rooted,and i have another problem : the phone restarts by itself and gets stucked in the boot loop, i never flashed a new rom ,it is running the stock rom,Someday i needed to factory reset the phone so i rebooted into recovery mode (power + home button +vol up) ,. I booted into recovery mode but the power button does NOT react as 'select' button although it works just fine for power on and off. I select a function and press [power] an the first line becomes the selected. pushing it again just flashed the screen. But pressing it long turns the phone off,and even after the factory reset from phone directly(with out going to recovery mode)

General :: Android Device Landscape Mode Lacking

Jun 16, 2012

Since i have an android device and tried some roms for this device (HTC One S)and its dissapointing to see that landscape mode is so lacking in the space that could have been used in messaging apps.

Its quite annoying (for me atleast) to have to withdraw my keyboard whilst typing something because the one i am texting with has sent something new.

I understand that this is not a place for requests, so my question is, is there any way to make messaging look like this (this image is not real)

and not like this..

I am not looking for a specific rom that allows this, im just looking for anything that makes this possible on any rom.

General :: Boot Smartphone As Non-smartphone In Power Saving Mode

Aug 23, 2013

Is it possible to reboot an Android smartphone as a non-smartphone(Like a Nokia 1100) ? Just enable only services to make phone calls and everything else remain disabled(Slow down the CPU to the lowest clock speeds, lower bit depth, turn off all on-board electronics other than those necessary etc). Motivation is to save power. In my phone most of the power is consumed by Android OS (and not screen). I was wondering if I had a mode like that I could keep the phone alive in case I can't charge the phone immediately, by switching into this power saving mode.

General :: Flash Device With Broken Screen And Debug Mode Not On

Jan 28, 2014

I have a completely broken screen/lcd/digitizer on my Samsung Galaxy S3, debug mode was not on. The phone works as it will still vibrate when turned on and the LED / Menu / Back buttons light up during a boot. USB connector works as well. The phone was not previously rooted.

I had most important data on the sd card and I've already wrote off any other data on the phone as I've since moved on to a GN2. I would like to make use of the S3 (not necessarily as a phone but a server, security camera, etc.). I've read several posts here about my options and looked at numerous google articles, all seem to require debug mode being on or assume/require the data/OS must remain as this is what the user is trying to recover. I do not care if all data is lost on the phone, I just want to make the device useful again.

Am I out of luck if debug mode was not enabled or can I flash through adb via some obscure mechanism? Also note that fastboot is not an option here as the S3 (samsung) does not have it enabled. I am unable to get into "Download Mode" as I cannot see info on the screen.

General :: Using Fastboot Mode To Flash Recovery Image - Device Not Detected

Apr 24, 2012

I deleted /system folder on my nexian cosmic journey. And now my nexian is stuck...

I try to using fastboot mode to flash recovery image, but my device seems not detected. I already installed the android composite driver, but when i use "fastboot devices" command, it shows (?) So how the heck to get my nexian back to normal?..

Or perhaps, if i just be able to put back the /system folder to its place again, it would be more easy to recover it... But how access the root when phone is like that?

Android :: Phone Goes To Power Save Mode

Oct 4, 2010

At first when I used my phone. I would click on Internet, Browse to a web page, and if left my phone alone for a few minutes it would go to power save mode, and I would have to unlock the screen to keep browsing on the same internet page I was on. Now when it powers down, and I go back to it, it always defaults to my home page, and I have to browse back to the page I was just one. I have been looking for a setting to undo this, as its driving me crazy, but I haven't been able to find a way to change this.

HTC Desire : Slow Power-off On Device

Jun 22, 2010

Has anyone else noticed that the Desire seems to power off VERY VERY slowly, or is it just me? Literally, and with no exaggeration, I hit the power button on the phone to power it down at 10:38am, and as of 10:56am the thing is STILL trying to power off.

I don't turn the phone off very often, but every now and then it's worth it, but it's taking far too long and I keep having to pull the battery. Anyone got any thoughts?

I'm assuming theres an app that is causing all the bother, but I can't think what. Anyone know of any apps that have this sort of problem? If noone knows, I'm going to have to factory-reset the phone, and I really don't want to have to set it all up again.
