[Q] Battery used by external SD - AT&T Samsung Galaxy S II SGH-I777

Does it use extra battery to play music from the external sd card as opposed to playing it from the internal memory of the phone? I've heard this from several places and I want to see if anybody can confirm.
Other than that are there any differences between the two?

Never noticed a battery drain from it. I regularly go with and without an sdcard in my phone. Sdcards are fairly low power.
It'd be good to see some numbers on power draw for sdcards.

It does use more power to have an external SD installed (whether you do IO to it or not, it draws some power), and even more to do IO. But the amount of additional power is negligible.
Flash (=SD Card) uses more power when writing than reading.
The external Flash uses no more power (or about equal, it depends some on the specific Flash chip type) than the internal Flash, though. So if you're playing music from one or the other, provided you're not doing a bunch of other stuff at the same time, it's close to a wash and certainly not enough to worry about. Click the volume down one or two clicks and you're likely saving more power than the Flash chips are drawing...

Good to know

Non-removable battery - Dealbreaker?

Hey all,
There doesnt appear to be a topic specifically on this(I have searched) so I have to ask.
Does this cripple the phone for you?
My personal situation:
Have an x10i
Long time SE user
Planning on upgrading in the next month
The two cons with this phone for me are the lack of an SD slot, and the battery. With google music and the like I can totally deal with the SD failing. But the battery, its got me totally conflicted. Ruining a dream phone. I've had several SE phones and their programming isnt great. Even just the other day my X10 crashed twice and I had to pull the battery. This is what worries me.
Thoughts?

No and no
The phone has built in reset button combinations (hard-coded so will always work). I don't see other than that, why the battery thing is a problem Unless you plan on keeping the phone for a very long time (read: to the point where the battery cant hold a charge) it's not worth losing sleep over. There's a few threads on how to remove the battery I believe as well, and by then your warranty will be up anyways, so who cares if you unscrew the back .
The no SD thing is also not a problem with the amount of internal memory available + USB OTG support

Ah jaysis, there were big rants about this on another forum and there was ZERO mention of the fact that it had a hardcoded reset.

Thanks.
@Mods: feel free to close.

1st. The 32gb seams to do me at mo (may not be good for app hoarders) at the end of day the battery will die before watch 1 season of (e.g family guy) or half way through 1 good space hungry sd using game, so why do you need it full up. 2nd. Batt is not a problem unless you carry spares around with you. Hard reset = (power button and vol up) works same as pulling the batt out. this was my same worrie when read about it myself at first.
well, i forced a bootloop to test the "hard shutdown" and it works
Think about the HTC X devices, they are only coming with 16gb and dropbox as backup.

That's the one s. The one x has 32gb, just like xperia s.
About the sd card slot. I really don't miss it. 32gb is more than enough memory for me. In my old phone (htc desire) I had a 32gb sd card and never took it out of the phone. If you need some removeable memory for whatever reason usb on the go will do, but I doubt I will ever need it.
The the battery. Well running around with spares is not something I ever did. I usually just bring a charger or usb cable if I'm away from home for a while. If you are in places where you have no access to power, you could allways buy an external charger. That would basically do the same job as extra batteries. If you're worried the battery may wear out over time: it is removeable if you unscrew the back. So It can be replaced if needed.

Yes, the X has 32, same as us. Given how much stuff I have installed I would think I would have less space, my 4S was a 32gb and it was mostly full with half the apps and a few more pics and videos.
+1 about the charger, I have some old Nokia N882/N95 micro USB cables that I use as backup and might even buy:

[Q] Time occasionally resets - CM7

Hi there,
I've installed CM7 on a 4GB SanDisk Ultra internal SD on my Streak.
Occasionally, after a reboot or shutdown > boot I lose time settings (defaults to 2010)
Has anyone seen this, or know why it happens?
Thanks!
most probably the internal battery is dead...
workaround:
goto > settings > date & time
and make sure automatic is enabled...
that way your phone time will always sync with your telco provider...
It has an internal battery? Where is it? I may have knocked it while changing the internal SD.
Note though, that the normal battery is always inserted.. so it should have that to keep the time.
Automatic is set, but it doesn't sync.

i dont think you would knock the internal battery by accident...
the battery is really near the internal sd card, it looks like a metal button...
if the main battery is at 0% and dont charge, eventually the internal battery also would discharged also... i also had the time when the date is back to 2010...
and all i have to do is just reboot the phone and my telco will adjust it automatically...
Well I did have it in bits when I changed the internal SD, I should probably check it.

Edit: Can you indicate where it is on this image?
http://guide-images.ifixit.net/igi/f1LAPoqeQFlFKhML.large
lol.. you look at the surrounding area of the internal sd card and see if there any metal button look alike...
if the insertion of the internal sd card considered as bottom, then the internal battery is located at the upper left of the insertion...
that is the internal battery...
Oh that thing!!
I will see if I can check it for damage.

Burst mode not as advertised?

One of the biggest features that reviewers kept touting was this thing's ability to fire off 20-100 pictures in a blast, and that the shutter speed is near instantaneous.
In the month I've had this phone, I've...never quite experienced this. Usually when I take a picture, it'll kind of pause for a second and then go. Not terribly slow or anything. Still a bit faster than any other camera I've had. However, if I hold down the button in an attempt to capture more than one picture, the result is this:
It'll often pause for about 2 seconds, then one little preview image will "pop" over to the icon in the corner, and then I can hold the button down for 6-8 more seconds, and after it "saves photos" the result is 4. I think the most I've ever gotten is 5. If I have the sound on, it'll make the "shutter" sound like 3-4 times a second, but I'll still only end up with 2-4 pictures. Usually takes one picture about 2 seconds after I press the button, and then one picture taken right as I took my finger off the button. Also, unlike the previews i saw where each picture from burst mode is a nice action shot, I just get 4 images that are completely out of focus 80% of the time.
As far as I know, this is the same whether I use the physical or software shutter button. Is this..normal behavior?
Edit: Wow what do you know. I just tried it 4 more times because I'm sitting here thinking about it, and one of the times I actually got 9 photos! At least I know it's capable of it.
I get several photos in burst mode. But I definitely don't get as many as the shutter sound goes off. Frequently I expect 8 or 10 But only get 3-5. But I have gotten as many as 15.

Turn off the image cap in the camera settings. I don't remember which drop down it's in, sorry. It helps a lot though. Just remember that I'd toy take too many pictures, it'll take a while to load.

Not currently running sense, but when I did it worked great...took dozens of pictures, instantaneously with 0 lag
I'd say a factory reset is on the horizons...or a trip to your local s&r center
Where are your pictures being stored? Does it save them to on-phone storage or does it save to a micro-SD card? If you're using a micro-SD card, that may be the cause of the delays. Check what class the card is, should have a letter "C" printed on the card with a number inside it indicating what class it is. A class 4 card is pretty common and inexpensive. A class 10 card has much faster read/write speeds but is also more expensive. Many DSLR cameras (especially ones that do 1080p video) have minimum card class requirements in order to quickly write pictures to the card while shooting quick bursts or high resolution video.
^ If that's the case, you could probably change the setting to store the pictures/video to on-phone or internal storage and I would presume it should perform as advertised until you are able to obtain a higher class card.
I have a class 10 card in there that it saves the pictures to. I bought it because it had great reviews for it's speed. I can imagine if the "saving photos" step would lag if you had a slow card, but I don't know why simply the act of taking a picture would be any slower. I guess I could test it out, but that would make me kind of mad if so.
Another thing I just noticed. If I launch the camera app by pressing the camera icon, it pops up almost immediately. If I press the physical camera button in order to launch the camera app, it takes about 4 seconds to launch.

Did you do an actual test on the "class 10" card? Get SD Tools and run it. Post the screenshot here. Also did you format the SD card with the phone or with your PC? It does make a difference. Try saving pictures on the actual phone storage and then post results. You can't use a SD card and then complain it doesn't work as stated. From the sounds of it it's your SD card's fault or you just got a faulty device. Also make sure to turn off the picture cap like someone stated.
If that doesn't fix it and a factory reset doesn't either (make sure to clear Wallet settings before doing this if you use it) then the phone is defective because I and many others (as a matte of fact from a quick search this is the first thread regarding this) don't have the problem. The only thing we all have though is the physical button vs screen button opening lag. I remedied this by just setting a shortcut on my lockscreen to camera, I think HTC is aware of this issue though.

That definitely sounds like your SD card isn't capable of keeping steady speeds to me.
While I don't get an 'icon pop' for every photo captured, I've had no problem getting 20+ photos in burst mode. Although, I will say it seems depend on what you're capturing. Just one example being: If flash is on (or is on auto and used) and I try to get a burst shot I'll usually only get between 10 - 15. Class 6 micro SD, here.
Where is this image cap setting, i looked in all the drop down menus and can't find it

I just tried it twice and I got 20 photos each time, does that mean I also have an image cap on? (no SD card)

Under Continuous Shooting.
Tapatalked from my shiny new HTC Evo LTE
Your phone must be messed up. I have used continuous shooting from day one and it works as advertised. Like others have said what settings are you using under camera. I'm on MeanRom and have never had a problem. For a test a changed my continuous setting to 50 pics instead of 20 and it took all 50. Also, a class 10 card is a waste of money unless your using it in a camcorder or 18mp camera. You won't see any benefits in a phone. Class 4 is more than enough speed for this phone and any phone. If you look at what the class numbers mean it is strictly speed for writing not everyday access to the card.
I've noticed that how many pics it takes per second is pretty dependent on the shooting conditions and settings. Have you tried setting the camera back to default settings and shooting in daylight? It makes sense that it shoots slower if you have low light or settings are such that the shutter has to stay open longer.

True - to an extent. I'd say most cards on the market don't live up to their class rating. Especially if you are buying cheap cards off of Ebay or Amazon.

Actually, I'm curious to test this out. When I'm outside in ideal conditions and I want to take a picture, I simply frame the picture and snap a shot. When I use continuous shooting is when I'm indoors and I want to capture something crazy my pet bird is doing, and lighting conditions are maybe less than "perfect".
I'll try taking the cap off. I noticed there was a cap, but since I never got to 20, I figured why do I need to take it off anyway.
Also don't worry about the SD card. I'm a pretty frugal shopper. I probably looked through the reviews for about 45 different 32gb microSD's on newegg before I decided on this one. Then, I used a combination of coupons and small gift cards to get it down to $2. I certainly didn't pay much

Under "Continuous shooting" deselect "Limit to 20 frames." I just took 53 in a row, no problem.
use the internal storage. its write is almost 30 MB/s compared to class 10s being 8-10 MB/s (my pny class 10 is 8 MB/s write)
The zero lag camera, excellent quality with pics, macro, video etc are some of the best aspects of this cell. Coupled with the Mic, noise canceling filters, low light filters its truly amazing. Ask any iPhone user who compared, they will tell you the truth.

Was on stock and now the team pkmn rom, and my camera always works as advertised. Using a class 4 32g. I'll snap off 20-50 pics pretty unbelievably fast. After I'm done, I do notice a moments hesitation though, especially with 50ish shots .

i cant get passed 45..but could care less because i keep the 20 limit cap on anyways...I may unlock the cap at the Pepsi 400 this weekend.

[Q] Two problems....

My droid razr maxx will not charge anymore. Looking at where the cord plugs into the phone. I can see that it looks as if one of the contact leads on the end has worn down and is kind of rounded off. Now, being that i cant charge it. Verizon sent me a new used replacement. Which seems to work fine. However, None of the pictures and downloads that i thought i had moved to my 16GB SD card when on the old phone are in fact, not on my SD card. My pictures and downloads are now stuck on what they call "Internal Memory" because i cant charge my phone.
So now my questions are; #1 Is there any way to possibly remove the battery so i can get a charge on it another way? And, #2 How do i set my default saving of data to be put on my SD card. And not in the "Internal Memory"? So i can prevent losing everything again...
Thanks in advance...,

[Q] Recovered SD card, now what?

Hi guys..
I recently had to format my 16 gb transcend external sd card as it was shown to be damaged by my S3. I formatted, recovered data using remo recovery. Now on checking the drive is fine. Before it showed the drive health was poor and major failure with boot sector 46 failure and all but now it shows excellent health. Some of the photos recovered were damaged, but 90% were fine. The problem is I dont know why this happened and frankly not sure if my card will let me down again. Is there a good chance for the failure to occur again?
Yes... chances are your card will fail again.
Contrary to popular belief, SD cards are not to be trusted. They have a limited lifespan (very limited), which is shortened by each write cycle made to the card. That means the more you write to each, the shorter it will last. The memory cells actually "wear".
Although the memory cells found in SSD drivers also wear, their controller know this and keep track of what cells are to be considered worn out, so nothing is written to them again. This prevents data loss, but the drive's size is always shrinking (byte by byte, over the years).
With memory cards there is no such thing as an intelligent controller, so when the cells start wearing off, the whole device MIGHT be compromised.
I really don't trust USB flash drives or memory cards that already have a history of data loss. I usually keep them for extremely unimportant tasks, and that DOES NOT include have them in my phone or camera.
