New Update Causes Severe Battery Issues

After updating to IOS 10.3.2 one iPhone 6 user issued a complaint that their battery was 80% and then suddenly decreased to 50%.  More and more users have also experieced this problem that there battery has dropped a quantum amount. I think that there is probably a flaw in the system and the new update has bugs and flaws which needs to be resolved immediately before more users experience this problem and give Apple a bad name.
You can actually stop the installation by declining it until the company resolves the issue
