LG G3 D855 turn off at 30% battery.

[merklol]

Hello everyone,
My phone has had weird behavior recently . It's suddenly started to turn off when I still have 30% of battery remaining. And then I plug in my phone to try to charge it, it shows 0%. It constantly repeats. I tried to battery calibrations apps and its methods but it doesn't work. Is my phone battery dead? Would someone give me some advice what I can do in a such situation?

Welcome to the forums. It could mean that the battery is starting to fail. Can you replace it for a new one?

Thank you
In fact, I had kinda a similar issue about a year ago. I changed a battery of the phone, but it seems it's going to happen again. I can buy a new one, I am not sure if it will fix the problem though.
