Device Watch Files

Fixes

• Since-charge screen time: an app that was already in the foreground when the period started (e.g. watching a video while unplugging) is now counted — only the part after the anchor, never time from before it
• Battery: the background service no longer polls every 5 seconds if it restarts while the screen is off
• Since-charge refreshes can no longer overlap, so a slow refresh cannot overwrite newer data
• The since-charge page now explains missing data: a notice is shown when usage access has not been granted, and the over-a-week warning no longer disappears together with the app list
• Average drain now follows the device locale correctly

Requires Android 8.0 (API 26). Signed with the same release key as previous versions — installs as a normal update.
