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.

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?

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.

General :: Google+ Application Cache Size Is Huge?

Jan 15, 2012

I went to do a nandroid backup and it failed, "no space on my SD card".

Thats weird, as usually have at least 4 gig on my Nexus S 4g.

Poking around, it was the cache from Google plus,).[url].... That, coupled with my titanium backup of same ate my SDCARD. easy to fix Titanium from backup it up, but the cache is still several gigs large. 40,000 + files with [number].screen extensions.

I have like 2 friends on google+, 3 posts, and can not for the life of me figure out what in the world all that data is.

I'm going to remove the data , freeze the app, but just wanted to know if noticed a disproportionate amount of data in the Google+ app compared to the amount of activity/usage I have on google+.

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.

General :: Internal Memory Consumption - Hidden Files

Feb 21, 2012

I have only 150mb of internal memory on my phone. These are some items that consume critical amounts of internal memory space. When I download an app, it seems I am downloading an install package. The installed app itself takes up additional space. I believe the install package persists on the internal memory, invisible to the average retail user, and takes up internal space even after the app is moved to the card.

Ex: an anonymous app
android market listed size- 3.51mb (this must be the download size of the installer)
download and install on internal memory, size listed- 5.73mb
move to SD card, size listed- 2mb
move back to internal memory, size listed- 5.73mb

Further thoughts:

1. The install package seems to remain on the internal memory even though the app moves to the card.

2. Beyond the above example, I went through each and every item listed in my settings - applications - storage use - All.

I found 105 total items on internal memory and SD card all together. By adding up the listed "Total" size of each (yes, I went through each and every one), I arrived at approximately 109mb. The phone lists internal memory use at 135mb. I would expect the internal memory use to be LESS than 109mb because some of the apps are on the card. My assumption is that much of this extra internal storage is taken up by all of the installers sitting invisible on the internal memory.

3. Based on observing the change in the Internal Memory usage when I delete app "Data", I believe the app data is being written to the internal memory even if the app is on the SD card.

Why isn't the install package deleted after the app is successfully installed? Is there an app for that?If I uninstall the app while it sits on internal memory, does it also delete the install package?If I uninstall the app without first moving it back to the internal memory, does it delete the uninstall package? How can I reclaim this internal memory space for actual use??

General :: Google Maps 6.10.0 And Extra Memory Consumption?

Aug 19, 2012

I own a (quite old now) Google Nexus One and I recently upgraded from Google Maps v6.9.0 to Google Maps v6.10.0

And I was quite surprised to see my user memory decrease a lot while the install apk is quite the same between both versions.

My Nexus One is rooted and running stock Android 2.3.6 (GB, not ICS)So I investigated and here is what I found about this new version of Google Maps.First, you must know that the memory available to the user to install new applications is mounted by the android system as '/data'.By running a 'du' command, I discovered that the following folder:

Code:
/data/data/com.google.android.apps.maps/app_
takes 11.9 Mo, which is a lot.[code].....

General :: Battery Is Fully Charged But Cannot Power The Phone?

Feb 28, 2013

I purchased an extended battery, a Motorola branded BP7X for a Droid 2 phone. It's rated at 3.7 volts/1820 mAh. I tested it with a volt-ohm meter and got a reading of 4.2 volts.

When I install the battery in the phone and connect the charger (phone is off), the charging graphic shows the battery is fully charged. I can power on the phone with the charger attached, but as soon as the charger is disconnected, the phone dies. I tried this battery in two Droid 2 phones and got the same behaviour. Is this an indication the battery is defective, or is there something I need to do to make the battery work?

General :: Polaroid PMID701C Tablet - Battery Consumption Graph

Jan 7, 2013

Recently bought a Polaroid PMID701C tablet. I was looking for that battery consumption graph that is on most android phones/tablets. The one where it shows which apps and hardware are consuming the most power. i couldn't find it and gave up. until one day when a low battery warning appeared on the screen. usually i cancel it, but this one time i clicked OK and it brought me to the battery consumption graph i was looking for.

seems to be the only way i can access it. i understand that this tablet is entry level, but shouldn't i be able to get to this without having to wait for a low battery warning?

my android phone's power button stopped working a few weeks ago. It wasn't a big problem, but a few days ago, the battery died. Now it is turned off and I can't turn it on. When I put it in charge, it just shows the charging screen. The phone is a Winmax W8000 (Winmax is Bangladeshi company. I'm from Bangladesh). It runs on Jellybean (4.1). It wasn't rooted. I tried to get into Download mode, but pressing the volume buttons and plugging in the charger doesn't work.

General :: Android Phone That Will Auto Power On If Connect To Charger?

Feb 1, 2013

Im looking for a Android powered GSM phone that will automatically turn itself back on if the battery is dead and power is reconnected.

I want to stash this in my vintage automobile and use tracking software to locate the vehicle in the unfortunate event its stolen. The only issue I need to solve is if the battery dies and the phone turns off how to turn it back on automatically. I plan to put the device in the door panels so access will be difficult.

General :: Use Power Button To Turn Phone Off Without Getting Unlock Pattern Every Time

Feb 22, 2012

Got a question regarding the lock screen. I'm on 2.3.5 on a Skyrocket. If I let the screen timeout and come back to it in a few minutes, when I power on, no screen lock (just a wallpaper to swipe away). If I use the power button to put it to sleep (not physically power down), the next time I use the power button to turn it on, I'm presented with the pattern unlock screen. Is there a way to use the power button to turn the phone off without being presented with the unlock pattern every time (I'd like it to do this after maybe 15-30 minutes, but not immediately as it seems to be doing it now).

General :: Samsung Galaxy Pocket S5300 - Odin Only Detect Phone When Power Is Off

Odin only detect my Samsung Galaxy Pocket S5300 when the power is off.

In a meanwhile:
- Odin cannot detect in Download mode.
- KIES is able to connect, detect & do the backup.
- I've tried many versions of Odins.
- Odin(s) is able to detect other phone (Galaxy Mini S5570).
- PC could detect the driver and do the file transfer.

Why only when the power off id:com turns into yellow (or green in Odin 3) ????
