Battery usage test with HDD on OTG - Nexus 7 General

I have a USB-powered Western Digital hard drive that works with my N7 using an OTG cable. I was curious as to how heavy the battery usage would be when powering a spinning drive so I did a small test, playing the same movie from the hard drive and then from a flash drive. Here’s what I saw (I charged the N7 between tests, usage number from battery monitor measure of charge level):
Stock 16GB N7
Play movie with MX Player Pro through Nexus Media Importer
Duration of 1 hour, screen at 100% brightness
Video: 832 x 352 1503 kbps h264 MP4
Results --
Sandisk Cruzer 64GB Thumb Drive, FAT32 -- 12% battery drain
Western Digital My Passport 500GB Portable USB 3.0 External Hard Drive, NTFS -- 23% battery drain

Larger MicroSD Cards = Faster Battery Drain?

Just bought a 6 GB MicroSD storage card. Works great. However, I'm wondering if anybody here knows the science behind these things.
Does WM require any more processing power to keep track of a larger volume?
Additionally, would a MicroSDHC card drain the battery any faster than the same size MicroSD card?
SDHC should not require more power as a specification. Since there are no SD cards as big as SDHC cards, its impossible to directly compare.
Every flash chip uses a different amount of power. It is possible that some SDHC cards may use more power than others, just as some SD cards use more power than others. However, this amount of power is quite small.
Generally, the higher the speed rating for the card, the more power it's going to consume.

Low fps with DiamondTv and Tvuplayer

Hello
Does anyone of you Diamond Touch owners have good fps when using DiamondTv or TVUPlayer??
And what have you done to make it work?
With DiamondTv i try to stream DR (Danish national Tv) with 950kbit. Buts its playing with lower than 10fps even with Wifi.
Tried to play streams using Tvuplayer. But i only gets streams with low fps.
Its like the CPU i way to weak.

I'm having the same problems with my Touch Pro. It's like watching a slide show. Supposedly it run smoothly on the Mogul, so I can only assume it's a settings issue, I just don't know what those settings are.
I'm slowly chugging along getting things working. I installed CorePlayer instead of TCPMP and that didn't work at least not right away.
I had to copy/paste the CorePlayer "player.exe" into the TCPMP folder for TVU to launch it instead of TCPMP. Now I'm just trying to find the right combo of CorePlayer settings for smooth playback.
I've been using SpikeTV with Star Wars on for benchmarking, but I haven't been able to get a combo above 60% yet.
I've got Smooth Zoom off for everything, and got the following results so far:
GDI
High
27%
Raw Frame Buffer
High
29%
QTv
High
65%
QTv
Medium
47%
QTv
Low
39%
DirectDraw
High
40%
DirectDraw
Medium
51%
DirectDraw
Low
57%
I've gotten some varying results with QTv, from 40%-60% with high quality being better than low quality and vice versa. I'm really not sure what's up with that.
I'm hoping I can find some other settings to tweak with DD or QTV get smooth playback.
Low Fps
Did some testing on Touch Pro Qualcomm caused the issue, Samsung Omina & SGHi780 working fine due to CPU diff.

Sling Player Mobile?

So what are the best settings in sling Player Mobile to watch NBA basketball without the video freezing? And what bit rate/resolution/whatever should I set it to that will allow me to watch about 2 hours every weekday without going over the 5GB AT&T limit?
Anyone have any ideas?
resolution always 320x240 (QVGA)
and the max bitrate... well do the math.
bitrate is the amount of bits per second. you know the amount of hours per week, so convert it to seconds per month. then calculate the max bitrate so it won't exceed your dataplan...

ASRock N68-S overclocking

Hi
On sunday i bought a asrock n68-s motherboard and a AMD Phenom II X3 720 Black edition processor and i cant figure out how to overclock in the bios.
I have tryed increasing the multiplyer from x14 to x16 but then i restart and it doesnt boot.
The spec of the pc follows:
phenom II x3 720 2.8ghz
asrock n68-s mb with untied overclocking technology
2gb of samsung pc 6400 ddr2 ram
500w psu
can u help?
thanks
Instead of raising you multiplier, try to lower it 1 or 2 steps, followed by lowering your HTT multiplier, then set FSB:Mem freq = 1:1, then raise up the FSB by 10% of increasing number, if you can't boot try to raise up core voltage & northbridge voltage (becareful!!)..
First, you must know at how high your memory can run (both at tight timing & lose timing).. AMD platform usualy prefer tight timing to get better speed (at games of course..). It's your chioce, use tight timing at lower FSB, or use lose timing at high FSB..
P.S.
Some Phenom X3 can be unlocked to activate the other one core, so it will be recognized as Phenom X4 (not all X3 processor can be unlocked)..
Try to make some faults. Hehe. Go to Bios and set there. It will be probably there.
Other Problems!
Since i bought the pc bit it keep shuting down randomly on its own. And i dont know why
Can you help?
Check temperature of processor, chipset, & memory (at idle & full load)... If everything is OK, make sure you have a good PSU, sometimes voltage dropping over 5% can lead to system failure..
Also check shutdown temperature (overheat warning) at BIOS, make sure it's not set too low..
Yeah ive checked the temps and stuff and there is no reason why it shouldnt shut down. Apart from POWER!!! But i have tryed 2 psu's and no luck
Mine was doing the same.
I know you've tried 2 psu's but you didn't mention their power rating.
Also, often, cheap psu's lie.
I put an 800w one in, invested £30... it's running fine now.
about the OC'ing - leave the multiplier alone (can you even modify those on amd cpus?, cause on intel theyre locked) increase the fsb if that doesnt work try lovering the memory speed and then increasing fsb(works for me)! (for me the OC goes like this - open bios > cpu level up > set to "crazy" :d now its 3.1GHZ from 2.4 - used to be 3.4 until I started to mess around with it! the max I can get (while ocing manually) is 3.8Ghz stable enough to boot and play crysis!!! BTW its a intel Core 2 Duo 6600 cpu!!
oh and you should think of getting a cpu cooler(with stock cooler I had about 70C when OCd now I have 39C), or maybe a gaming motherboard(yes theyre more expensive, but you'll have easier life with utilities which will OC it for you in bios)!!
Do you think its the your PSU fault (about shutdowns) cause im using: C2D 6600 , Asus Striker II Formula, 4 kingston ram modules (4gb in total), NV GF 8800GTS 640mb, a HDD, optical drive, 2fans, and cpu cooler with fan!!! -- al of that is running on a 480W psu without any shutdowns and problems like that!
Ye the motherboard i got is an special ocing board
And is there any other names for fsb cause its not listed in the CPU Configeration. I up'd the multiplyer to 3.0ghz (about x15?) and it wont boot.
Takes about 7 times switching on and off to get working again.
Can i put my memory up to 1066?
My cpu is stock 2.8ghz, which is what it is now.

I sorted out the shutdown thing it was windows 7 beta had run out and was shuting down every 2 hours. But i went out and bought windows 7 last week.

I have dual boot system with WIN7 Ultimate and WinXp pro - didnt buy neither of them!!
Check this out http://www.overclock.net/amd-cpus/475649-amd-phenom-ii-x3-700-series.html look at those OC's if you can get all that stuf (fsb ...) in the same speeds then you can go pretty high with your cpu -- but dont overheat it - I reccomend a good CPU cooler like Zalman CNPS 9700 Led (I have one )!!! vut sometimes you cant get as high because of the mobo!!!

smart dock performance drop.

a while ago i bought an original Samsung smart desktop dock.
the one with 3xusb, hdmi, and audio ports.
one interesting feature it has is desktop mode, when you attach a mouse it disables the phone's screen and sets all automatically rotating apps to landscape.
there is just 1 minor problem with it: this desktop mode causes a performance drop, enough to lower your 3dmark score by 10%.
i first noticed this issue when plugging in my mouse suddenly made games in ppsspp(psp emulator) run much worse than they usually do (58fps dropped to 40fps)
today i decided to test it with 3dmark and i got a clear difference in scores:
default screen mirroring: 3293
desktop mode: 2976
especially the physics tests got a rather big hit in performance.
it's rather strange that supplying images to 1 big screen at 1080i takes more effort than doing the same with a big 1080i and a small 720p screen.
