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.

I mean, am I doing something wrong? Is there something I don't know about? This is the super phone. It has failed the porn test. I see that flash is unavailable but will be soon. Is there an app?

I thought Sprint had really good nfl coverage. I checked the Sprint NFL app but there was nothing about watching games. I had sprint nfl on my old blackberry and I was at least able to listen to the radio broadcast. I saw a verizon commercial a few days ago that looked like they have nfl games broadcasted over the phone. Is there anyway to watch games on the Epic?

There are quite some pit falls that an application developer may hit. In order to simplify life Sony Ericsson Developer world has produced a little guideline called "Android Application Coding Guidelines - Power Save".

So I have been hearing mixed reviews about this does the epic have high quality you tube? Many people are saying it doesn't and others are saying that it is an option under settings that you have to enable to see the vids in HD. Does anyone know?

does SQLite have any big impact on power consumption? I am just thinking about storing data in a List or Map or in a database. I have a lot of inserts and queries, several a second.

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.

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.

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.

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?

I noticed that when I search for music videos on youtube, the official videos(which on the PC site of the youtube site are highlighted) don't search up on searches in the youtube app. Instead I'm left with a bunch of stupid fan made videos that are completely not what I'm looking for.

I keep trying to turn the screen off after i send a text or check something but nothing happens. I have to wait for the screen to timeout for the phone to go black. It stopped working today.

I am on the Epic 4g using the default YouTube app that came with the Epic 4g and I get an error every time I try to access my linked YouTube account. I have attached the screenshot of the error. This happens after going into the YouTube app, selecting "My account" then selecting my account from the "YouTube accounts" pop up. It will freeze for a while then I get the error in the screenshot.
I've even tried the HQ YouTube app found here: http://forum.androidcentral.com/android-applications/13492-evo-youtube-apk-works-droid-nexus-incredible.html
And taking the same steps as above it does the freezes but this time doesn't bring up that same error (I waited a couple minutes).
By the way, this is the stock ROM and I am not rooted.
