Stromverbrauch viel zu hoch!

[Corjan Meijerink]

Well OSM doesn’t have a navigation tool (SDK) for our development platform (Flutter). So yeah, pretty impossible.

As the battery usage is caused by the map rendering, we are looking into workarounds for that, but pretty complex too

I get another answer from HERE next week so I’ll just keep nagging them

Do HERE state the difference between their pure Android/iOS API battery usage and their Flutter version? If they're all bad, no amount of tinkering will bring the Flutter version round.

Another angle to investigate is whether their own app has the same battery problems:

• https://play.google.com/store/apps/details?id=com.here.app.maps

An hour or two's ride will confirm it's their problem, not just MRA's implementation.

And finally - a long shot, but if things don't improve then a possible fallback:

• https://pub.dev/packages/flutter_mapbox_navigation

I've no doubt there are holes compared to HERE functionality (no offline maps/routing?), but then again it might render with lower battery usage.

If nothing else it may act as a gentle lever/reminder for HERE to pull their finger out if you mention you're investigating alternatives.

@richtea999 thanks for thinking along
Their app (especially the Flutter reference app) display similar high battery usage.

@Corjan-Meijerink Oh, that's both good and bad:
Your code is good, Corjan!
And theirs is just a little bit sh*t.

They need a Flutter expert. And it's not me.

If they added it to pub.dev and made the API/interface open source on GitHub, they'd get some free feedback, possibly some fixes, and some publicity/sales, since it's the backend that makes them money.

Good luck discussing that with them!

Habe heute eine ca. 50 km Vergleichsfahrt gemacht, um die Akkunutzung zu testen. Auf dem Hinweg habe ich mit HERE WeGo navigiert, auf dem Rückweg mit MyRouteApp.
Die Akkunutzung unterscheidet sich gerade einmal um 3% zu Lasten vom MRA, siehe Screenshots.
Anzumerken ist noch, das HERE WeGo während der Navigation 8 Mal abgestürtzt ist und MRA 1 Mal in den Offlinmodus gewechselt ist.

@hawebo exactly! Thanks for confirming this
The root cause really is originating from the HERE map rendering. Quite frustrating.

@Corjan-Meijerink

Considering that this long standign issue is hindering the further development of MRA, and is annoying your user base, maybe you start negotiating a price reduction from HERE?

Usually, tyhat is a language they understand

Könnte MRA in dem Fall nicht erwägen, auf die Kartendarstellung von TomTom zu wechseln?
Damit wäre die Planung von kurven- bzw höhenreichen Routen einfach und keine anschließende Übertragung/Speicherung nach HERE mehr erforderlich.

@Corjan-Meijerink Just for your info, the change in the last SDK appears to have made the power consumption problem very much worse for me with no change in my installation setup and/or use. With the previous SDK, my Google 6 Pro would slowly charge up to 100% and that is why the last change in version to 4.0.6 232 (with SDK change) appears to have drastically changed the power consumption for the worse with me losing 80% of my battery over 4 hours whilst charging yesterday. Other nav apps allow the battery to charge on the same setup. Thought this might help with feedback to HERE and to maybe help you.

Scroll up to the awnser of Corjan
HERE is the only map provider that supports the Flutter design platform. Since this app is being developed on that platform, it is not possible to choose another map provider for the navigation engine.

@Rob-Verhoeff i understand. I also understand that i cannot use Next until this problem is solved.
