Battery&memory optimization

[myneur]

Memory

• Fonts (finally 11k saved: now 53k with one event)

  • ✅-500: fontMinutes shared with fontSmall

  • ✅-6000?: remove some i18n glyphs from fontSmall

  • ✅global vars

• ✅3-4/9 of 333B icons used: bitmaps2fonts (when all icons used) (9 icons: 3000 B, font 1700B)

• enum instead of dictionary

• not saving calendar_colors

• array to be checked by item array length instead of dictionary

• merge sort instead of bubbles

Battery

• prevent repetitive rendering except for metrics

  • minute changed => redraw: arc, metric, now, event time

  • data changed => redraw all

  • metric changed => redraw metric

• calendar dynamic scheduling

  • ✓ Turn data loading off when no BT

  • Dynamic data loading frequency:

  • ✓ loading quickly after layout,

  • ✓ then in lower frequency.

  • investigate: how quickly to load after error

  • ? Stop loading after auth error and warn it's not loading.

• precomputation:

  • events and markers

  • positions like notification

• jump tables to choose activity <=3 | <= 1 <=5 | ==0 ==4

Stats

• no redraw => 0-1 ms

• just activity => 1-2 ms

• calendar without events => 2-3 ms

• full calendar => 4-5 ms
