A few weeks ago I noticed that my battery was reading 100% for much longer than it should given how I was using my Droid 4. Suddenly, the battery dropped to 90%. Since then, I have seen the same behavior when charging or discharging; I simply can't get an intermediate value! To be fair, I do get 15% and 5%, but other than that I only read 10,20,30,40...100%.
My Droid is rooted and is running 4.0.4.
Has anyone seen this before or have any suggestions?
