There are plenty of answers regarding the capacity of Gold High Capacity Batteries. I feel that it is time iFixit takes a good look at those as well.

iFixit seems to be the place people turn to for answers. It might be worthwhile to post a test regarding the "Gold High Capacity Batteries". For this test Apple iPhone 5 batteries were used because they were needed for replacement work anyway and would not be wasted to be used for only this test.

The Batteries are offered on multiple outlets like Ebay.com, Amazon.com and various other online stores. The prices for those batteries are usually 50% higher than for a regular battery. That by itself would not be bad, if those batteries truly have higher capacity storage.

Here is the side-by-side of a Gold High Capacity and a standard run-of-the-mill iPhone 5 battery Checking the weight for the Gold battery it was at 0.830oz The standard battery weight 0.848oz.

  • Width of the Gold Battery is 32.01 mm vs. 31.5 mm for the standard battery

  • Length of the Gold Battery is 91.72 mm vs. 90.30 mm for the standard battery

  • Thickness of the Gold Battery is 3.86 mm vs. 4.04 mm for the standard battery.

  • Expectation was that the Gold Battery would show difference in physical attributes that would be significant to its claimed increased capacity, which it did not
