[bug] wrong battery level reporting using bluetooth hands-free set
asked 2014-12-21 21:43:15 +0200
[technical information]
- phone software: currently 1.1.1.27, observed bug in older versions, too
- car: VW Golf VI (2012)
- hands-free set: "Mobilfunkvorbereitung Premium" (using HFP)
- The phone view of my car's onboard computer has a battery icon with 4 bars (example image (not from me): http://data.motor-talk.de/data/galleries/0/111/506/37845626/mfa-1-2446891996949761149-2518887524033295729.jpg - first of the three icons below "Telekom")
[observation]
- The car's battery icon displays the remaining capacity in an unusual way:
- 100 - 95% --> 4 bars ("full")
- 95 - 30% --> 3 bars
- 30 - 10% --> 2 bars ("half-full")
- 10 - 5% --> 1 bars
- 5 - 0% --> 0 bars ("empty")
[expected behaviour]
As you can see, the range where the car's icon says "3 bars" is too high. I'd expect the following ranges:
- 100 - 80% --> 4 bars ("full")
- 80 - 60% --> 3 bars
- 60 - 40% --> 2 bars ("half full")
- 40 - 20% --> 1 bars
- 20 - 0% --> 0 bars ("empty")
[other phones]
Other phones which I have access to are Lumia 925, iPhone 4 and Samsung S4. All of them do the battery level reporting as I've expected. So I think the bug is not in my car's software but in jolla's.
seems reception level is showing the same behaviour for me (I don't have battery level showing in my car) btw: there is another report at (https://together.jolla.com/question/25112/bug-wrong-phone-battery-level-shown-when-jolla-connected-to-the-cars-head-unit/)
