[Galaxy Note 3 Accessories] TMaLuST:
People are in search of an extended battery which fits the original case.

While I know that most of these batteries are scams, I am in search of a brand who can deliver a bit more power to our beloved note 3.

Today I tried the MPJ 4500 mAh battery with NFC (it works).

I used a free app from the play store to fast discharge all the batteries.

The MBuyNow was tested twice, the first test has been done on the first discharge of this battery, it came with 60% and it charged itself from 58% to 100% in 1h and 13m with the stock charger. The second test was done after 10 cycles of charge/discharge.

The stock battery was tested once in order to have some comparables.

The MPJ battery has been tested one time, after 17/20 cycles of charge/discharge.

So, let me describe the four tests:

Common factors:​

- Both batteries were charged to 100%, then I rebooted the phone, unplugged and plugged again and waited the confirmation that the battery was really 100% charged;

- Fast Discharge has these settings: "High CPU load; Camera Light; High brightness display; GPS receivers; Operated Vibrator; Network Connection."

- As soon as I unplugged I started the "Fast Discharge" app with everything flagged on but "operated vibrator".

- I never moved or used the phone; I forced h+ network only (wcdma); accounts syncs were off.

- Phone has been in the same spot for all the tests to make sure that network and wifi signal was as costant as possible.

1) Mbuynow battery: - I received 13 whatsapp messages, 21 instagram notifications and 20 messages on facebook;

- Battery drained from 100% to 5% in 2h 2m and 9s.

2) Stock battery

- I received 14 whatsapp messages, 11 instagram notifications and 25 messages on facebook and 1 gameloft notification;

- Battery drained from 100% to 5% in 2h 17m and 53s.

Ok here comes the second and last test of the MBuyNow battery.

3) Mbuynow battery 2° test after 10 charge/discharge cycles:

- I received 29 whatsapp messages, 60 instagram notifications and 41 messages on facebook;

- Battery drained from 100% to 5% in 2h 11m and 42s.

Today I tested the MPJ battery.

I just finished the test with the MPJ battery, so let me explain what I did.

I turned air conditioning on in order to reach aprox. 20°, which was the temperature back in January when I tested the previous batteries.

Moreover I followed all the rules I used in my previous tests: same app to fast discharge, same conditions, same networks, same place ecc..

The only thing that has changed is that I am on X-Note rom, but on stock kernel.

Before writing the results, I have to say that the battery discharged to 5%, than I removed it from the phone in order to weight it. When I powered the phone on, the battery indicator showed a 15% battery remaining. I decided to run the test to discharge the battery from 15% to 5% once again. This behaviour happened another time and the battery was at 8% so I ran the test again. This means that I have 3 results, 2 partials and 1 total.

4) MPJ battery after 17/20 charge/discharge cycles:

- I received 19 whatsapp messages, 2 gmail Notifications and 18 messages on facebook;

- Battery drained from 100% to 5% in 2h 11m and 52s.

- Battery drained from 15% to 5% in 11m and 13s.

- Battery drained from 8% to 5% in 3m and 13s.

If you consider the total time, the battery lasted 2h 26m and 18s. If you want to consider only the first discharge the battery lasted 2h 11m and 52s. If we do a simple calculus, we can say that if 95% of the battery lasts 131 minutes, then 10% of the battery should last aprox. 13 min, which is not far from the 11m duration that the battery had in the second discharge.

After the test I weighted the three batteries and all weigh aprox. 50gr with 2gr of deviation.

When 100% fully charged the stock battery weights aprox 61 gr while the MBuyNow aprox 58 gr with 2gr of deviation. The MPJ weights 62 gr.

Below you will find some pictures and screeshots, I think I mistakenly deleted the screenshot of the first mbuynow test and of the 3rd discharge of the MPJ, but I was smart enough to write everything down on paper! :)

In conclusion, this kind of test is not really precise in terms of mAh but I think that it can give us a way to compare these batteries with each other.The MPJ battery does not clearly have 1300 (40%) mAh more than the stock battery, but 8/15% seems to be a reasonable amount. The MBuyNow 3900 mAh battery can be considered a good - cheap - replacement for our note 3, but it clearly doesn't add any extra mAh or hour of usage.

Any other battery you want me to test? :)​
