Perfine Extended Battery Replacement 6000mAh for LG G4 BL-51YF H818 With 2 Battery Covers Black-Gold

Love the extra battery life on an aging phone. Cases supplied are cheap feeling, but OK. They lack the NFC functionality the standard back case has.Does increase the thickness, but it's still thinner than a 3210 was back in the day. Would prefer if the case was only larger where the battery pokes out (like the iphone battery case), but this might have made it difficult to get in and out of a trouser pocket.Note: the included battery will come partially charged; this is normal (best practice for li-on/li-po batteries) and not something to leave a bad review about.

This battery appears to work for my phone. I have many apps and use it regularly for navigation. It is chunky, but worth it. The charging is slower.

Very impressed with this. Yes, it does make the phone a little bulkier and heavier but you get much improved battery life and it is so much easier to keep a hold of. The original back felt quite slippery and always seemed on the verge of sliding out of your hand onto the pavement.

Excellent extended battery for the LG G4. Lasts most of the day on heavy usage. Sure the larger size of the battery creates a bulk at the back, but this is nicely covered by the 2 cases included in the package.

Works pretty well for now. Time will tell what the battery's lifetime is.

This battery was draining at a rate of knots. Obviously defective, had to get a refund and dispose of said battery.Looking at the other reviews this hasn't happened to others so might be just bad luck.

This is the only replacement battery that has been any good.

Great battery ive got used to the little extra bulk.
