My LG G2 battery charges very fast and discharge very fast

my LG g2 was running very good with battery but suddenly mobile goes off when 30% charge was left but after restart it shows 7% battery. and when i connected charger battery charging speed was very fast it went upto 50% just in 10 minutes. After that consistently my phone goes off form any battery position but when i connect charger it goes to 100% suddenly even though battery was at 20% before shutdown

Welcome to Android Central! The battery might be failing. Since the battery is not user-removable, you can bring it to a repair shop. There are probably DIY battery replacement videos on YouTube, if you want to try opening the phone up yourself.

Look at Settings/General/Battery. Tap the graph. Look for a sudden drop to 0. If you see it, the battery is throwing a dendrite. (See Lithium Battery Dendrite links for more than you want to know about the subject.) If that's the case, the battery has to be replaced.
