MPJ 6440mah Extended Battery Review​

Few days ago I received an extended battery for the Note 4 from MPJ.

The size of the battery is x2.5-x3 bigger than the original Samsung one.

It holds up to 6440mah and the packages comes with an extra back cover for your Note 4.

As we can see from the picture above the design is user friendly and the colours match exactly as they should match. Overall the design is not boring and it is eye catching.

Now the back cover has a gloss finish and it is also thicker and taller so the battery can fit correctly.

It does add an extra bulk to your device but from my perspective I don’t think it’s that much noticeable. Note 4 is already a big phone adding some extra height won’t be a problem, but yes it doesn’t look as good as with the original back cover. I had zero problems in everyday use with that back cover, not even with pockets.

Now let’s start talking about the battery life and how it performs!

Day 1 :

The battery life was just how I expected! As we saw earlier the battery has 6440mah which means 2x3220mah which is the capacity of your Note 4 original battery. With the OEM battery you can get 6 hours of Screen On Time (SOT) in 16-18 hours of total use. With this extended battery I managed to get 12 hours of SOT from the very first day! How awesome is that ? The pictures below talk by them selves.​

Day 2 :

I have charged my phone through the AC. The battery life was awful! Only 7:30 hours of SOT, which can be achieved from the original battery also. I think my AC in that specific room is a little bit faulty that’s why the battery drained out so quickly.

GameBench :

I ran also GameBench to test out how many hours the battery can hold up playing Traffic Racer. I have played for 15 minutes and i lost 3% of battery juice. GameBench claims that the phone can last 6.5 hours playing this game from a full charge.

Day 3 :

I have recharged the battery from 7% to 100% from a power bank and I am at 62% at the moment with 4 hours of SOT and 10 hours of total use. That means the battery is doing better than Day 2.

In total i got 11 hours of SOT and 1 day and 4 hours of total use, which is great! I managed to get 2days with a single charge check out the screenshots below

The battery charges quite fast, i managed to charge it from 8% to 100% in 2 hours and 5 minutes.

​

Conclusion :

Pros :

- Battery performs great, it can last 2 days with medium to heavy use and can reach up to 12 hours of SOT

- In very light use it can last up to 3 days. (It drains 2% every 8 hours on idle with WiFi on)

- Full Idle can last up to 5 days (I believe even more)

- Beautiful Design and Colors match perfectly

- Feels great in the hand

- The extra bulk is NOT a problem

- You can buy it either with NFC or without

- The cutouts for the speaker,S Pen, Camera are perfectly aligned in the correct position

- It does add some kind of protection

Cons :

- The back cover has a gloss finish, it would be much better if it had a leather texture like the Original Cover

- Charging on AC is very slow compared to Power Bank

- The battery without the back cover can fell off , its not tight enough.

Overall its a great battery, having 12 hours of SOT is amazing.

The extra bulk was no problem for me instead the phone is heavier and it feels more solid.

I recommend this battery to everyone that uses their Note 4 heavily. People who think that 6 hours of SOT is not enough should get this battery.The only downside is the back cover, I wish it could have a more premium feel although I will continue to use this battery on daily basis

NOTE : When restarting the phone you get some extra juice between (10-30%) , that happens because the phone can read up to 3220mah and it gets confused with that extra battery power.​
