What's new

• Battery history by day and by hour: bar charts of battery used and charged each day. Tap a day, then any hour, to see screen-on time and which apps were on screen.
• Older dates: imports the ~2 weeks of battery history Android already keeps, then keeps up to 120 days.
• Works without Shizuku: history, per-app battery usage and Battery Saver in Boost use one-time USB permissions instead of a helper app.
• Force stop without extra apps through the built-in accessibility helper.
• AR branding: new name and logo.
• Fixes: hour details no longer disappear, no duplicate battery readings, history import no longer stops partway.
