Mobile devices issues #5

Open puzrin opened 9 years ago

puzrin commented 9 years ago

Mobile devices can have different behaviour:

in background tabs
when display is turned off

This ticket is to track state of things

Timers at mobile devices

Browser	Background	Display off	Background WW	Display off WW
Android browser	OK	fail	OK	fail
Android FF	fail	fail	OK	OK
Android Chrome	OK	OK	OK	OK
iOS Chrome	OK	fail	OK	fail
iOS Safari	fail	fail	fail	fail

iOS Safari - sometimes timer in background can continue working 0-20 seconds
iOS Safari - foreground tab continue working 10-15 seconds after display turned off
Conclusion
Everything is bad on ios. The only solution is to reselect master.
On android things are acceptable, if you generate timer events from WebWorker
SharedWorker will not help:
- not supported in browsers with timer problems
- not much needed in browsers without timer problems
