Introduction

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.

The prototype board was then connected to the EBD Constant Current Electronic Load capacity tester. Shown here with the standard battery connected Same connection is made with the Gold Battery (test in progress) Here is the result for the standard battery

Conclusion

Looking at the results from this test it clearly shows the Gold battery has a capacity of only 1376mAH. This is 49% less than advertised on the battery as well as the websites where these batteries are sold.

This test showed that while the Gold High Capacity Battery did not have a higher capacity, it is not any worth than the standard battery. So it would be okay to purchase these batteries if the buyer would want a standard capacity replacement battery for a higher price.
