Hi, mates! I have a very strange issue with a battery. I just replaced an old battery with a brand-new on my Lumia 1520. That time I was on the last available issue of W10M. And the highest value of possible charge was 82%. I made a factory reset - nothing changed. Then, I decided to roll back to 8.1 using my Mac, and got that annoying error with driver, phone becomes bricked. After a long manipulation I made it alive finally! On 8.1. But it still stuck on 82% at charge. What the trouble and how to solve it?
