What People Are Saying

Rated 3 out of 5 by from Charge Up, Phone down Bought this as a back-up battery for my LG-G4 phone. It charged up quickly in the battery charger I also purchased. Placed the battery into my phone and the phone would not boot because of the boot-loop issue. Now I have a nice, new battery for a dead phone.

Rated 5 out of 5 by from After a year, good as new! Okay... I bought this battery a year ago, wondering if it would be as good as the original. I've accidentally let it drain completely on several occasions, and it always charges right back up and lasts me the day. (I don't do a lot of talking, but I have loads of apps running in the background.) I'm sure there must be some degradation after all this time, but I don't notice it. I just now pulled the battery for the purposes of this review, and gave it the ol' spin test. It's just slightly swollen, probably from me letting the 'phone get too hot in the car. Overall, I'm very happy and wouldn't hesitate to buy another directly from LG if ever I need one.

Rated 5 out of 5 by from Amazing Battery keeps me going Having a spare battery that's ready to go in those emergency situations is a lifesaver. Thank you LG for providing an affordable backup

Rated 5 out of 5 by from Great price and quality! This review is for the LG G4 battery. When I needed this, not only was LG the best price, for a couple dollars more I was able to get a an extra wall charger! I researched several sites and was concerned I would get a knock-off. By buying directly through LG I knew I was safe.

Rated 5 out of 5 by from Good battery life This battery lasted for hours even with the gps activated the whole time. I can be playing games, music, and using my location at the same time and it will still last at least 5 hours. LG is the way to go.

Can this battery be use on lg g4 beat?

Asked by: Kltan
The LG G4 Beat Dual SIM H735DS with dual-SIM card slots, Model # H735DS was never released in the U.S. and regrettably, we do not have information on it. The G4 Battery, Model # BL-51YF will fit in the LG G4 variants that were released in the U.S. and they may have different dimensions to the LG G4 Beat which means this battery will not fit. Please contact the LG Support Center in Singapore for assistance, http://www.lg.com/sg. You will find contact information on their site...^IFV
