    Default iOS iPad 3 memory issues

    I've got an application developed in Sencha Touch 1.1, it's running native using Cordova/Phonegap.

    It works great on iPad 2 and iPad mini. Usually, it works great on iPad 3 too. However, when it opens a Sencha Chart graph it might crash.

    When I'm looking in the XCode console, I see that the appliction on the iPad 3 receives memory warnings quite often. The iPad mini and iPad 2 doesn't. That's unexpected, since the iPad 3 has the twice amount of memory and the application doesn't use more memory on the iPad 3. It uses about 85MB.

    Does anyone have a clue what's going on?
    Code:
    "APP[123] <Warning>: Received memory warning."

    Yes, the iPad 3 spec wise has more resources but it actually performs worse than iPad 2 in many areas. iPad 4 was released same year as iPad 3 and fixed many of these issues. When I bought the iPad 3 and compared it with iPad 2, many things felt slower and jittery. Was unhappy with that purchase.

    That's interesting. Good thing to hear that the iPad 4 performed better.

    Default Available Options to Solve Memory & App Termination on iPad3?

    Hola -

    I have a modest tab panel application that has several carousels each with around 16 (1.x mb) photos each. It runs fine in a web browser & in the iOS simulator but crashes (after the memory warning) on my iPad3. The crash occurs whenever a carousel tab is selected a second time.

    Are there any available options to try on the iPad3? I can't very well tell my customers - "oh, you should fork over another $500 for an iPad4 to run my app". ;}

    I've tried removing each carousel as different tabs are selected - no joy. I've also seen a "Maximum number of files open 78" on the device console log on some variations as I experimented with the multiple carousels.

    Any insights would be most appreciated even if only to note that other developers can do these simple apps with no problems on their iPad3.

    Thanks!
