Introduction

Firstly, I want to pay attention on costliness of this battery in comparison with Chinese analogues, which can be found on eBay. I have ordered the following Chinese battery, and also arranged the following 5400 mAh battery with Mugen Power representative.

In the following review I will test 4 kinds of batteries: battery from Mugen Power (5400 mAh) - example #1, Chinese Noname analog (5200 mAh) - example #2, battery from Mugen Power (4500 mAh) - example #3, standard battery from Samsung (2500 mAh) - example #4.

Delivery

Example #1 delivered in vesicular polyethylene with instruction and solid package. Battery Door Back cover from example #3 completely similar with example #1.

Battery package from Mugen Power 5400 mAh

Chinese noname #2 also delivered in solid package with vesicular polyethylene inside.

Chinese battery package 5200 mAh

Both packages have sent in the same time and delivered after 25 days +/- 1-2 day.

Appearance

As I have told before, example #1 Battery Door Back cover perfect came up to example #3, but Chinese battery #2 immediately disappointeded me:

- firstly - "native" back plane of battery don't want to enter to "native" slots phone case

Incorrect slots on Chinese battery 5200 mAh back cover

The incorrect slots became cause that back cover won't completely closed

- secondly - example #2 was thicker than, example #1 or 4 and back cover from Mugen Power batteries cannot become worthy replacement for Chinese battery

Comparison dimensions of examples #1, #2 and #4

All examples (can observe what examples #1 and #3 are equal)

The back covers have a different view

Testing.

Testing was done on the 3 directions:

- Loading test from Antutu Tester;

- Test for charging battery from 1% till 100%;

- Maximum endurance test time.

For all batteries have created similar conditions: Wi-Fi and 3G were enable all the time, phone has using for web-surfing and for books reading during time directly proportional to the battery capacity

1. Loading test from Antutu Tester

From-left-to-right (example #1, #2, #3 and #4)

I was surprised by performance for the example #2, twice rechecked data

2. Test for charging battery from 1% till 100%

3. Maximum endurance test time

Conclusions:

It was my goal to determine whether two batteries from almost the same place but with different cost (example #1 approximately 8 times more expensive than the example #2) can compete with each other?

My answer is - No, they cannot because of the following flaws of the example #2:

- incorrect back plane cover, which not suitable with phone case slots;

- not very distinctive capacity and very distinctive maximum time of work;

- and i'm not sure, if this miracle of Chinese thought will not explode my phone;

The low cost and the unreliability or the high cost and the quality - the choice is yours.
