A lot has changed since this was answered. Here is the latest on the "Gold" High Capacity batteries.
Since I had been working on
a batterytest regarding this exact question, I figure I might as well post the test as an answer until I get around to creating a Wiki for this.

There are plenty of answer regarding the Gold High Capacity Batteries on the internet but I feel that
it is time we on ifixit take a good look at those as well. After all, ifixit seems to be the place people turn to for answers. Here it goes:

I figured it might be worthwhile to post my test regarding the "Gold High Capacity Batteries". For this test I used Apple iPhone 5 batteries simply because I needed some replacements for replacements anyway and did not want to purchase something I would only use for this test.

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

For my test, I used two Apple iPhone Batteries. One is advertised as a standard 1440mAh while
the phone, but it'll would takeGold battery is advertised as 2680mAh. Price for the standard was $7.20 and the Gold was $10.79. Both, the standard as well as the Gold battery, had a lot longerwide range of prices. The Gold battery was always higher.

The equipment used for this test were:

1. K9201 Fast Battery Charger Activation Circuit Tester

2. EBD Constant Current Electronic Load 3A 20W 12v battery capacity tester

3. 6x8cm Double Side Prototype Board

4. Battery Connector Apple iPhone 5

5. EB Tester software V1.8.5

6. USB
to TTL Serial Converter Cable for the capacity tester

7. Pocket Digital Jewelry Scale

8. 150mm Vernier caliper

Item number 1 and 2 are tools I have been using to test and
charge batteries for repairs and were not exclusively obtained for this test. Item 3 and 4 were needed for the difference wouldeasy of connected the batteries to the capacity tester. I soldered the battery connector to the prototype board and attached two wires to it.

Those were connected to the capacity tester.

For the report I will simply refer to the standard battery as “standard” and the Gold High Capacity” as “Gold”

I decided that I did
not want to test these batteries simply by placing a large resistor as a load. The current will decrease over time since the voltage of the battery will drop. Due to the constant resistance but the drop in voltage and current, the result would be notto inaccurate to properly calculate. I opted for the battery capacity tester so as dramaticto assure that the current supply remains the same regardless of how the battery voltage changes. This would guarantee that the power consumption on the batteries would stay consistent throughout the test.

Both batteries went through 6 charge/discharge cycles prior to the test. Both batteries were fully charged via the K9201.

The physical properties of the batteries are
as follows:

'''Standard'''

Height 90.30mm (3.55 inch)

Width 31.50mm (1.24 inch)

Thickness 4.04mm (0.158inch)

Weight 24.04 gram (0.848oz)

'''Gold'''

Height 91.72mm (3.61inch)

Width 32.01mm (1.26inch)

Thickness 3.86mm (0.152inch)

Weight 23.53 gram (0.830oz)

No significant difference in properties

After measuring the dimensions on both batteries,
it sounds. My advice, total ripoffwas time to connect them to the battery capacity tester. The test program was set to a constant 0.500A (500mA) so as to not drain the batteries to quickly and stay awaycausing physical damage to the battery. The cutoff voltage was set to 2.9V since this is the voltage where I found most lithium-ion batteries do no longer get charged through the device.

Here is the synapse of the test results

Looking at the results
from it...[http://www.youtube.com/watch?v=zOwreQQNTJw|Check this video] BIG surprise!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.

yair18, I'd stay away from any of the "Gold" batteries being sold on certain auction sites. These batteries have been around for a while and most of them are standard batteries that have just been relabeled. You will not find any difference compared to a stock battery. If there would be such a battery it would not damage the phone, but it'll would take a lot longer to charge and the difference would not be not as dramatic as it sounds. My advice, total ripoff and stay away from it...[http://www.youtube.com/watch?v=zOwreQQNTJw|Check this video] BIG surprise. Hope this helps, good luck.surprise!
