Why Apple does not have a backup battery for Apple devices?

Why Apple does not have a backup battery for Apple device? Recommended us that of our full when we are on the road, so they should do a backup battery for their devices instead of other companies do. The backup battery that I use for my iPhone 5 c don't let my phone screen timeout as he does when I'm with the regular wall charger. Can anyone help?


Consult the manual for your backup battery.  There should be a switch or a button to activate the phone load.  It should not be left in charge mode all the time because the phone thinks it has unlimited power when charging, so disabled several energy-saving features (like display sleep, closing a connection Wi - Fi when he sleeps).

    Why Motorola does not have hands-free box?

    I have all kinds of helmets that work very well.

    As to why the bike not turned in the box - I would say that most people do not use them. You may disagree, and perhaps it is regional. But looking around the United States and the European Union, most of the people with cell phones do not use wired headphones. And the few people I know that do, tend to buy a different brand of what is in the box.

    In the United States, you can get them in many stores for less then $10 for Motorola is saving most of us who do not use wired headphones. I have a set that runs in my backpack as a backup, but I always forget it's there and use the phone without it.

  • Why Canon does not have old adapters for my SLR camera lenses? I can get them with Sony, but not for Canon

    I have an old Canon Ftb with a goal of 1.4 fd. I'm getting into digital cameras now (just to have a 12 G for now, mainly used for underwater photography). I would like to stay with Canon, but I'm very annoyed that Canon doesn't have a way to continue to use their old lenses. Nikon, for all their flaws are much better at you can continue to use your old stuff.

    Then I find that if I'm going to Sony (Yes, really, Sony) can I use my lenses from Canon ol via an adapter. This my Canon, tell me it ain't so. You must have a way, I just have not yet discovered.

    There are many challenges with this and the "adapters" are to be considered with a certain scepticism.

    The FD lenses are mechanical - no electronics.  The case of the unit, on the other hand, has an electronic interface for the lens - nothing of mechanics.   This means that if you set the goal, you would have to manually set the aperture but also of manual focus of the lens.

    Your Canon DSLR had a split Prism focusing in the viewfinder to help.  A new camera does not work.  The reason why there is no help from the development is because most of the lenses are autofocus so it is simply not necessary.  This makes it particularly difficult to tell when you've worn exactly the goal.  Making it even more difficult is that any device with a sensor size of APS - C (most of them) have a small viewfinder that you had on your Canon SLR photography.

    In addition, the lenses are optimized for a specific back focus distance.  Canon's EOS cameras have a depth of 44 m from the mounting flange of lens at the front of the body at the level of development within the body.  When you use an adapter, it modifies that distance.  If you change too much, the lens behaves as if it is mounted with extension tubes, the entire range of focus is moved closer to the camera, and it can be is no longer able to focus to infinity.

    There are 3 parties that make these lenses... conversion kits but they do them for a few drinks (not all) and that they require a bit of surgery on the goal (e.g. this level which protrudes beyond the rear of the lens used to set the aperture value should go).

    But... the modern lenses are just so much better than the old FD lenses.   Requires really quite the dozen FD lens to make it interesting this fuss.  Also, I own a Canon SLR (AE-1) and a few glasses of FD... but have no interest in trying to use one of these lenses on my EOS DSLR cameras.

    I think that this question almost as Ford asking why they do not wheel adapters let wheels it T model mount on a Mustang of 2015.  The new wheels are so much better than the old wheels, you want to continue to use the old wheels.

    Leave your old lenses in the past.  Mine are on the shelf alongside my AE-1... body as a conversation piece.  I don't actually use them.

  • File.upload ActionScript does not work on Air SDK for iOS devices

    I try to use the ActionScript File.upload to transfer a file on Air SDK for iOS environment, but the File.upload does not work properly. No event on the file upload handler is executed after File.upload is called, and no exception is caught. When I check the side network traffic server, I found no application http even didn't hit the server after execution of File.upload. The code is below.

    When it is run on the simulator of the Air, it works very well as expectedand the file is successfully downloaded to the server. But when run on iOS devices (in my case, iPad), as I explained at the beginning, no event on the file upload handler is executed and not the http request has even hit the server. So I think that the problem may come from the client side.

    During my attempt to solve the problem, I found something complicated about this problem on iOS7. In other words, if you call the URLLoader.load method (although the URLLoader.load points to an address non-existed) before calling the File.upload method, the File.upload will work as expected on iOS7. Specifically, when the above OnTrickyButtonPressed method is run before the OnUploadButtonPressedmethod, File.upload will succeed on iOS7. But this only happens on iOS7. On iOS8, File.upload still refuses to work, regardless of knowing if the URLLoader.load is executed before.

    I think in my case, the problem is not the problem of sandbox or a session of Firefox problem described in the two links below, because not even a http request hit the side server. It seems that the Air SDK for iOS comes to fail send the http reason request any.


    http://StackOverflow.com/questions/351258/how-do-i-make-Flex-file-upload-work-on-Firefox-a nd-safari

    To make my problem clear, I list my environment below:

    • Development environment: Windows7 (64-bit) / Mac os 10.9.4 (tested on both OS platforms.)
    • IDE: Flash Builder 4.7
    • Air SDK: 3.8 / 16.0.0 (after that I have updated to the latest Air SDK 16.0.0, problem persists.)
    • Application server: Tomcat7 + spring

    Finally, I want to mention that download the file using URLLoader.load isn't an option in my case because I want to download large files in the future, which cannot be addressed with the URLLoader.load.

    I struggled with this for days. If I really appreciate it if anyone has an idea about this.

    Thanks in advance.

  • Why Lightroom does not have "save under"?

    Often, when you change a single image, "save under" would be more useful, instead of export, which is much more complex to use you have to change the destination one other things.

    Thank you

    Not sure if I understand what you want to do, but...

    The changes you make in LR are automatically saved in the catalog, and you can close the program, start it again and continue where you left off.

    You can then see your previous changes in the history panel. There is therefore no need (or ability) to save the image.

    If you need an image for a spesific purpose, use of export.

  • Acer does not have any spare part for the B326HK monitor.

    I bought on 11.06.2014 in the monitor of Belgium a B326HK 4 K and it was after 2 days already broken. The monitor has been sent to the Acer service center, but it seems that they have no spare parts. I've had better service expected of Acer. Their explanation is that it is a fairly new monitor and they can get difficult spare parts. Are there people who are facing this problem?

    @ Cory. Today I finally received news of Acer with the message that the motherboard of the monitor showed an error. Because apparently these motherboards are currently difficult to obtain, Acer will send me a new monitor. When I read here on the forum about problems that have other owners of this Acer B326HK, I think they could actually sit with the same faulty motherboard in their monitor.

  • Why HCL does not list the conditions required for the 4.1?

    I tried the last document HCL (July 1) to determine if our current hardware (IBM x 3650) is supported for the 4.1.

    The last entry is 4.0U2, but nowhere in the document see when SOMETHING is listed for 4.1.

    Can we get up a new HCL which includes 4.1?  I am planning an upgrade and suppose that x 3650 will work with 4.1.  The hinky given matrices requirements I see in other parts of the whole package (my eye is on you, SQL database matrix...), it seems that VMWare needs to devote a lot of resources to update the doco and explaining why they need increase their db requirements!

    > if a 4.1 update will be at high risk or low risk

    4.1 update IMHO the risk is low. And you can reinstall 4.0u2 anyway, if something goes wrong. Should be hmmm... about 20 minutes.
