Hello.
Very rarely, this happened a few times already and quite annoying since I have seen a couple LG Cosmos 2 phones show this same problem/symptoms. My m(o(m/ther)/a) and I have the same exact phones from a local Verizon Wireless retail store as a family package about two years ago. In my past experience, I have seen my phone lose all of its battery juice the next day even after a full charge at night even though I did not use the phone. Basically, the phone doesn't turn on because of no battery power. Connecting to its power charger will make it work again, but charging fully takes a few hours to be portable again. This happened twice so far for me.
Yesterday, the same thing happened with my m(a/o(m/ther))'s phone. She said she charged her the night before it ran out of battery power (dead as well) in the day time. She was able to turn it back on when she plugged a power charger (her SUV and at home). It also took hours to fully recharge and no problems.
We both use our own chargers and phones. We did not change any hardwares like batteries, chargers, etc. They are the same ones that we got when bought our phone as a family package from a local Verizon Wireless store. We don't know when the next incident will happen again, but this is annoying and concerning since there seems to be no exact patterns to see when this happen again. Why is this happening? Is this a known issue?
Thank you in advance. :smileyhappy:
