Phone restarting when reaches 70%

Hi, at start sorry for my bad English. I have problem with my phone. I replaced my battery 2 months ago, and everything was fine until now. About a week ago i noticed my phone keeps restarting when battery level reaches ~70%, I'm don't get red battery screen, just apple logo - sometimes it turn on shows about 65% battery and restart again in few seconds, sometimes its just black screen and restart again. It stops when I plug in charger and charge my phone. Anyone help?

Update (03/15/2017)

I replaced next new battery in iPhone service - that won't change anything - Any other ideas?

No I never got it wet.

App that shows battery life shows it has 10% condition and 0V voltage. ;(

Replacement batteries suffer from poor quality. Often times, they can be re-packaged old batteries with a new electronics chip (gas gauge) so that it shows 0 charge cycles.

The best way to know if your battery is good or not is to install a software like 3uTools and use it to check the battery condition (not the charge percentage). A good battery should be over 80% and considering your battery is new, it should be over 90%.

So while you think you are buying and installing a "new" battery, it is really just an old one. I recommend batteries from iFixit as they have been the most reliable for me to date.

I would download "coconut battery" app and get the status of the battery. Could need another replacement battery. I always recommend trying at least 3 new parts anytime I'm diagnosing a phone because of how likely replacements parts are to fail or not work properly.
