As a developer you can't fix it unless you own the product. Spending time improving performance when you "should" be working on "features" is not looked upon fondly by employers. Companies need to be defining acceptable performance (with metrics) on devices meeting certain specifications at the outset of projects, and failures on those tests need to be treated seriously. Can it really be achieved? Maybe not.
