Edit 11/3/15:

Link added for the MPJ 3000mAh battery w/12 month warranty:

https://www.amazon.com/gp/aw/d/B015...battery+g4&dpPl=1&dpID=41+r6n5cB9L&ref=plSrch

The battery is available as a single, (2) batteries with charger, etc.

There is also a 6000mAh extended battery configuration available.

The following is my review of the MPJ - Standard - GB/T 18287-2000 3.85V/3000mAh battery.

MPJ, which up until a couple of days ago I've never heard of, contacted me after reading some of my LG G4 battery posts on xda. They asked me if I would be able to do an independent review and testing of their battery. I agreed, choosing the battery model above.

It was shipped by MPJ from their San Leandro, CA location, and I received it on 10/30 Fri.

(see screenshots)

*My review will consist of 4 sections:

1) Charging times/rates/F°/dimensions

2) Usage

3) Comments/opinions

4) Conclusion

1) Charging times/rates/F°/dimensions:

The charging times below were taken using:

- Anker 18W Quick Charger 2.0

- Anker PowerLine micro USB cable

The dimensions of the MPJ battery were similar to the OEM battery regarding length & width.

There is a small difference in the thickness & weight of the batteries:

MPJ battery - 5.58mm/243.55g

LG OEM battery - 5.23mm/232.55g

The wrapper on the MPJ battery is slightly thicker, which may account for the weight difference as well. There is no difference in how the battery cover goes on or fits.

2) Usage:

Usage, including phone calls, web surfing, active smart voice recording and airplane mode:

10/31 Sat. @1:05pm - 100% —

10/31 Sat. @11:58pm - 10%

Usage on Battery - 11h 26m

Consisting of:

Screen on - 27% - 2h 50m

(brightness @90-100%)

Voice calls - 8% - 1h 11m

Browser - 6% - 46m

Smart voice recorder - on for 7h

Airplane mode on for approx. 6h

(See screenshot)

Overnight:

Charged phone a 3rd time.

11/1 @1:30am - 100%; phone left On, overnight.

11/1 @8:30am - 96%

After 8h; -4%

(Added +1h for EST)

After charging to 100%, I got the following usage:

Screen - 5h 11m (brightness @65%) Web surfing

(See screenshot)

Regarding the above charging and during usage, the battery has maintained a steady 71.6°F - 73.7°F temperature as per Battery Manager Widget by 3c.

*Interesting to note is that the stock OEM LG G4 battery has averaged 90°F. The MPJ battery is running 18° cooler. I'm not certain why the MPJ battery is running 25% cooler, but having a cooler running battery is usually always in the plus column.

3) My comments/opinions:

I always carry a spare OEM battery for any phone I have purchased over the years. I currently have (2) OEM batteries for my LG G4.

When MPJ contacted me and asked if I would independently review their battery, I thought about it. I didn't need a 3rd battery, and reviewing a battery would take several hours of my time, including compiling the statistics, taking notes and writing the review, etc. But after thinking about it, I figured why not.

My opinion would either be that the battery would either meet and/or possibly exceed 'my' OEM real usage standards or it would not. Whatever the outcome, I figured my results may assist others in their decision as whether to purchase or not purchase this battery. As far as I saw it, the only ones who had something to lose, if anything, was MPJ.

I had a choice between their 3000mAh and extended 6000mAh batteries. I chose the 3000mAh battery as I don't like the additional bulk an extended capacity battery adds to my phone.

I usually don't have high confidence in aftermarket batteries, as my experience is that they usually don't compare in real world use to the OEM batteries regarding battery capacity, usage times, etc., and the previous times I've tried aftermarket batteries, I have sent them back for a refund, and concluded my time isn't worth it to save a few bucks or to get 1 or 2 batteries and a charger for less than the price of one OEM battery from the manufacturer, in search of an OEM compatible battery. The only other exception to this was an Anker battery for my S3 which I was satisfied with, although I didn't do 'extensive' testing as with the MPJ battery.

4) Conclusion:

During real world usage as compared to the usage I've experienced with my OEM battery for a few months, I was like, ok, this battery is holding its own.

After using the battery for the past couple of days, I have concluded that this battery is at least equivalent operationally in real world use to the LG G4 OEM batteries I am using.

As I mentioned, I did real world testing on the battery, from the initial charging and the indicated charging rates, to phone call usage, to on screen time, to web surfing, etc.

Purchasing a spare OEM battery battery directly from the manufacturer or a supplier can be expensive, so many search online including myself for an OEM battery which sometimes aren't really OEM batteries, but are either counterfeit or have been on the shelf for a long time, resulting in loss of battery capacity.

It is very time consuming researching which 'OEM' battery has good reviews, including the reviews of the seller, etc., but can be worth your time because if you find an OEM battery from a seller other than the manufacturer, it can be 1/3 the price.

The MPJ 3000mAh battery is an excellent alternative to the OEM battery for the reasons I have mentioned above, including the real world usage stats, imo. During my usage, I have been very pleased with how the battery has performed, including it's discharge rate, cooler running temperature, etc.

If I notice any issues and/or changes with my future use of the battery, I'll be sure to ammend my review.
