Bests & Worsts Reviews from Amazon

Great battery. I can finally get 5+hr screen time on heavy use and full day standby time again. No need to plug during the day. I am getting overall 1.5 day on battery on LG V20 without plugging. Phone finally died at 4pm on day 2. Immediately ordered second one for backup. Hope it lasts, but time will tell. Most likely reason for all the negative reviews is that Android phones need to be calibrated to use high capacity battery. Here were the steps I followed to start to use this new battery: Replaced old battery with new 4100 one. Charge the phone to 100%. Unplug and restart the phone. If you lost 1-2% in the process, plug again till it 100%. After that, unplug and use till it reaches 0. Don't absolutely plug it before. Repeat the cycle 3-4 times. This will calibrate the android OS and it will recognize correctly the higher capacity.
