Gold, high capacity battery? What is that?

So i'm looking to buy a new battery for my old iPhone, and along the usual 1430mAh i've notice a lot of 'Gold' battery with high capacity of 2680mAh...

The first thought comes to mind that is a scam, but the seller have positive feedback...

What is going on?

Is this a good question?

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.

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 test 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 be 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 Gold 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 wide 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 easy 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 to inaccurate to properly calculate. I opted for the battery capacity tester so as to 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 was 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 causing 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

Standard Battery

Title:EB Tester Software

Mode:D-CC (Constant Current Discharging) 0.50A 2.90V

Begin Volt:4.189V

Cutoff Volt:2.904V

Capacity:1353mAh

Energy:4987mWh

Avg Volt:3.69V

Total time to reach the cutoff voltage of 2.9V was 9764seconds 2:42:44hours

Gold battery.

Title:EB Tester Software

Mode:D-CC (Constant Current Discharging) 0.50A 2.90V

Begin Volt:4.182V

Cutoff Volt:2.904V

Capacity:1376mAh

Energy:4969mWh

Avg Volt:3.61V

Total time to reach the cutoff voltage of 2.9V was 9933seconds 2:45:33hours

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.

Thank you for taking the time to test and report on this product - 3 years later and they are still being sold!!

Philip Pik you are exactly right. We as informed consumers need to let those that might fall into the "High Capacity" battery trap. Let everybody know that they are absolute nonsense. Thanks.

More likely to damage your phone I would stay well away from that.

If apple could make money on supplying a better battery do you not think they would!

I bought one. It was a scam, an ordinary 1430mah battery with a label on it saying it was higher. if you google 'iphone reports high capacity battery as 1430 mah' you'll find plenty of videos by people who got ripped off.

It sounds little strange because if there is such a technology, why the big and highet ranked compnay like apple do not know about that and does not have it! Even if they do not have this technolgy why do not cooperate or buy it from those who have! They know one of the most important factor for buyers is the mobile charge lasting time, by the way i have ordered one for my old 4s iphone and if it goes well and works i will buy for my iphone 7 also. So kan inform you soon about that.

askarians the reason for that is that the technology does not exist. Remove the label from your battery and you will find a standard valued battery.

It's a non-original battery with a higher capicity, so the battery will offer more energy and will run longer before it's empty then the original one.
