Rated 1 out of 5 by from Battery life is horrible! I will not be upgrading to a G6. The first G5 phone I had lasted about 6 months until it decided to crash, now I've had this replacement for a little over 6 months and the phone is now statically, restarts itself and battery life is terrible.

Rated 5 out of 5 by from Never worry about charging your phone. Get this and the cradle and you'll never worry about running out of battery again forever. Switch the battery through the modular in seconds your back up. That easy.

Does the battery for an LG G5 come of the base

Is this battery for the LG treasure? I know it sounds silly but it doesn't say it specifically after I type it in.

Asked by: Cwalk
I recommend to only buy the genuine battery made by LG. The others doesn't work that long. It's well worth the money to buy the genuine battery.

Does the battery have warranty? I got my phone in may and the battery has been acting funny at times. It will die overnight. I do not have it plugged in the whole day

Asked by: Lhlopez
The best way is to not over charged your battery by not having it plugged in for to long. This over charges the battery. Only needs to be charged enough for the fullest
