Battery drain when navigating

@richtea999 I’ll try that, although using Low Power mode solved the issue. I wish I knew what MRA was doing to consume so much battery though.

@Paul-41 a lot of battery drain is due to the rendering the maps on your device when online navigating. I guess the rendering remains although you've downloaded maps. The mapsupplier (Here) has to do (also) something to solve this. Google for 'battery drain' on this forum and you'll find more topics. It's under the attention of the MRA-team.

Probably redrawing the screen too often is my guess. However, that's easily written in a glib message like this, and a nightmare to fix as a developer!

One setting that might be useful would be a choice to decrease the app's screen refresh rate, so 1/5th second, 1/10th second, etc, so users could feed back on their findings. Maybe just in the beta.

I have to say I couldn't use my iPhone because it overheats and dims the screen, so I'll also be trying low battery mode this afternoon/evening. I had the same problem on a new Samsung Galaxy A54 this past weekend, so I'll also be experimenting that one too, at some point.

@richtea999, I happen to know that this has been tried, to as low as 40fps. It did not make any significant difference for the battery drain. It looks like something in the SDK is maxing out the processor. Slower phones seems to have less problems with battery drain, but that too is not always fully true.

@Con-Hennekens Thanks for the update Con. My bad guesswork.

[Con Hennekens]

@richtea999, I don't think it is bad guesswork at all It makes perfectly sense, but was already guessed by someone else before. Somehow it does nothing to the battery drain, and that surprised the devvers too. I will not be surprised when that turns out to be part the problem: the rendering engine does not limit itself to the set screenfrequency...

Any advances on battery drain issues?
Like the OP, I am using a quadlock wireless charger on Pixel 6 Pro and with 2.4a USB supply that just cannot keep up...

[Rob Verhoeff]

@Simannjo Still under investigation. I think Here has to come up with a solution.

[richtea999]

@Rob-Verhoeff Is there anything that users can do to help? A little direct customer pressure often hastens a result.

However, I don't want to step on MRA's feet, and sour their HERE relationship, of course.

@richtea999 I think Corjan is on top of this issue. In all honesty, I don't think that we can't do more than what's done as far.

I have been out this morning to have a nice ride in the UK heatwave. Very happy with the newest update. Firstly, I now have sufficient volume in my Sena Intercom. Secondly the phone didn’t overheat (although it was hot) and actually charged up to 99% by the time I got home. The motorway signs are good too.
