[Galaxy S III Accessories] DrGomez:
Testing XAiOX POWER 4300 mAh Li-Ion

Can we stick to the topic and discuss the 4300mAh here please? You can open or use another thread for different batteries. I'd kind of appreciate that -.- And why didnt the Thread Author post actual Battery Benchmark results?

You have to know...I am kind of a battery junky. I'm one of those freaks that run around with mobile chargers. I always did. With my iPhone 3G back in the days i'd get myself the Mophy Juice Packs and bulk it up to charge it on the going ;) Unfortunately there arent any such devices for Android Phones (at least, not that i know of) so i'm forced to buy extended batteries.

So, while others go and overclock their CPU and try to reach the biggest score on whatever benchmark, i go and find ways to extend my battery 'runtime' without having to turn off particular features of the smartphone because that wouldnt be productive at all. I dont understand people that turn off half their actually useful smartphone features, just to get a better battery life. I'd always return a smartphone, that doesnt cope with my daily use behaviour. But honestly, that's always been a problem with nowadays smartphones... they discharge too fast.

The battery life was one of the reasons why i got the new Samsung Galaxy S3, though. But i wanted more... obviously.

Batteries are produced in china. They need to fullfill strict stats before they can be approved for a usage in devices. Most of the times it doesnt really matter if it's a 10$ battery or a 50$ battery... actually, it is more likely that your 50$ battery has the exact same specifications and was probrably made in the exact same place as someone elses 10$ battery with the same stats. They usually just carry a different brand and maybe, but just maybe, better quality components.

But just like in...let's say... Condenser Mics ... it doesnt make much difference if there's a gold or an aluminium membran inside. It doesnt make much of a difference when it comes to "performance".

I'm not an expert but being a battery enthusiast at least, that's what i've been told by several different people that should know about this stuff.

EDIT: The best example to cover my arguments is that i bought this battery for 14,95€. Now the price for the SAME battery is at 29,90€

In fact... that's actually a bit suspicious but let's not be affected by that and get straight judge it for the test results.

TESTING the XAiOX POWER 4300 mAh Li-Ion Battery

So i bought this 4300 mAh battery myself. Im not sure if it's the same one... it kind of looks the same so i suppose it is. It's called "XAiOX POWER" and has a capacity of 4300 mAh. In reality probably less than that... but it should be more than stock anyway.

I decided to make a test that would be easy to reproduce for the people out there trying to compare it with their stock batteries.

First of all: I'm using the Jelly Bean Preview #5 of Cyanogenmod 10. It has been behaving pretty stable and normal... also, importantly, when it comes to battery life. At least to my feeling. Some claim that it drains battery more. Development is going so fast, that i didnt have the time to get the best possible combination of Kernel / ROM. I will most probably do so very soon but for now, i'm using Stock Kernel and CM10 Preview#5 which is going to work for this test because the way i did this test, it should be irelevant.

I will be testing the stock battery with the same configuration to avoid any bias. And to make sure this test is useful to those that do not intend to use this configuration. Especially as development is indeed fast on this device.

The actual test:

What i did with the battery when i received it was put it in right away without doing anything but restart the phone. When i turned it on it showed something like 66% I then charged it for some hours. Even though it was showing 100%, i left it charging for some hours to make sure the battery is fully charged. Honestly i dont know how the phone manages battery charging when reaching a status of 100%...

When i restarted it and plugged it off the charger, i was seeing normal battery discharge. Meaning: It seemed to me the XAiOX POWER was behaving like the normal battery. Imo that shouldnt be happening. It just seemed suspicious. So i fully charged it again, restarted and went into recovery to reset battery stats while still plugged in at 100%

When the phone was on, i eventually plugged it off the charger and started Antutu Tester to test the battery life.

Stats on Antutu (Note that Antutu changes the CPU Performance from normal to 100% and keeps it at 100% for the rest of the test) were at the beginning of the test:

CPU: 100%

Battery: 100%, 4.2V

Temperature: 35.0°C

After 30 minutes the stats were:

CPU: 100%

Battery 87%, 4.1V

Temperature: 46.2°C

After 60 minutes the stats were:

CPU: 100%

Battery: 76%, 3.9V

Temperature: 45.8°C

After 120 minutes the stats were:

CPU: 100%

Battery: 53%, 3.7V

Temperature: 46.0°C

After that i left it unsupervised for the rest of the time remaining.

Results:

After 3 hours under Antutu Heavy Load it was drained down to 20%

Battery test score: 561

It scored third top of the list before Acer Iconia Tab A500 and the Moto Xoom

Comparison test with the stock battery:

Same as with the 4300 mAh battery i charged it to 100% and left it charging for some time to guarantee it to be fully charged... then went into recovery and reseted batery stats. After that i left it charging still then after some time unplugged it and started the Antutu Battery Tester.

Stats at the beginning:

CPU: 100%

Battery: 100%, 4.3V

Temperature: 28.8°C

After 30 minutes the stats were:

CPU: 100%

Battery: 85%, 4.0V

Temperature: 42.0°C

After 60 minutes the stats were:

CPU: 100%

Battery: 69%, 3.9V

Temperature: 42.2°C

After 120 minutes the stats were:

CPU: 100%

Battery: 34%, 3.6V

Temperature: 42.7°C

After 2:30h the battery was down to 20%

Battery test score: 423

It scored 7th in the list... just above the Samsung Galaxy S2 and under the Moto Defy.

So as expected the extended battery did better than the stock battery and exponentialy speaking significantly better even. What does that mean? If you take this test and compare the results you will notice, that the more time passes, the more change there is in the results.

This is a high load test that only takes up to 3 hours. It'll drain the battery down as fast as possible. The 4300mAh having a 30 minute advantage to the stock on this test at the end, is a pretty good result. That time frame of 30 minutes will exponentially grow with the time you'd normaly use your stock battery with. I hope that makes sense to you.

The 4300mAh gets a lil bit warmer as you can see. That's all, though.

I hope this was a bit helpful to you ;)
