The screenshot is not of indicator-power, it is of System Settings. If the value is jumping in the System Settings graph, it can't be a bug in indicator-power.
The question then is whether it is a problem in upower, which provides the charging information, or in System Settings, which graphs the information provided. If the battery indicator shows the same percentage, the problem is not in System Settings, it is in upower. ** Package changed: indicator-power (Ubuntu) => upower (Ubuntu) ** Changed in: upower (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upower in Ubuntu. https://bugs.launchpad.net/bugs/1478321 Title: Weird battery values bq Aquaris 4.5 Status in upower package in Ubuntu: Incomplete Bug description: Many times it happens that the percentage of the battery shown is not the real one. Yesterday evening I had a big problem where the phone suddenly went from 20% to 0% and it shut itself down. This is shown in the battery history graph, that I attach. As you can see there are various vertical lines, clearly indicating that the value jumps from one point to the other. This is a big problem, because if one sees that the phone has still 20% of battery, one thinks that it still has 1/5 of its life span before dying. It is not the first time that this happens to me and others, and I believe that anyone experiencing this should attach a picture of it, so that eventually we might be able to resolve it, maybe with some kind of approximations.
