Read your battery's round-trip efficiency over the last seven days

Your battery dashboard now has a "Round-trip efficiency (7 d)" tile: how much energy you got back out compared with what you put in, measured between two points in the past week at the same state of charge. It also shows the cycles, the span and the state of charge used.

• When the energy readings cannot be relied on, the tile says so instead of giving you a number.
• If the battery never fully charged and discharged, the tile reads "No round trip in the last 7 days".
• The efficiency figure that used to sit on the chart below now lives in this tile.
• If the connection drops, your battery views keep showing the last known values and tell you how old they are.
