Power hungry

[Ralph Janssen]

In the beginning I had some problems with my phone. That was a android 9.
I have tested MRA on 4 devices, all android. (Samsung A32, A35, OnePlus Doogee T20 (8" Tablet) ) and don't have any problems at the moment.
The biggest thing I noticed is a quad lock charger, directly connected to the battery works the best. It can deliver more then enough power.

12V socket can be a problem, mostly because of the charger and cables you use.
Wireless charger can work. That is highly deepened on your phone. Some phones (I don't know how iPhones are) cannot charge large amount of Watts by wireless charge.

I had a problem with a low amp charger even though the cable was good. Moved to a fast charger and all is good now.

I cut the thumb off a rubber glove and cover the adapter in the socket on the bike to keep it dry. And use a cheap waterproof phone case. To keep my phone oneplus 12 and charging cable dry.

When off the bike ensure you cover the charging cable otherwise your phone won't charge till it dries, plus rain might damage the cable.

A squirt of WD40 also helps keep the cable usb clear of water. Learned all this the hard way, 6 hrs riding in continuous Welsh rain.

@Ralph-Janssen I have tried wiring the QL charger directly to the battery and it does seem to punch out more power . A bit worried about the fuse situation there though .

[Ralph Janssen]

@Bryn-Thomas
What about the fuse?
The QL 12V charger (with the 3 position switch) does have 3A fuse and some other protections.
So I don't see a problem to connect it directly to the battery

@Ralph-Janssen You are talking about the 12v to USB Smart adaptor. I am talking about the USB Charger . There is no 3 way switch .

[Ralph Janssen]

@Bryn-Thomas
The second one os a bit newer then the one above. I did not now there where more then one charger. And it does not look like it has a fuse.
And indeed, the first one I have on my bike.

What I read about the USB charger you use;
Quick Charge 2.0 (5V-2A, 9V-1.67A, 12V-1.5A)
So, if I'm correct, most smartphone charge with a 5 volt so it can only deliver 10W on the 5V and that is not a lot.
(I did not do a complete research so maybe iPhones can charge with 9v or 12v)
10W is probably not enough for using MRA next.
And of course your cable from the charger to the phone is important as well.

The charger I use (with the 3 way switch) has a 5v -3a = 15W output.
And that seems enough to charge the phone while using MRA next.

The first thing you can try is changing your USB charging cable to see if that is the problem.
Otherwise you can try to buy the other QL charger. Then your are fully protected.

@Ralph-Janssen Hi Ralph, thanks so much for taking the time to help me with this. It all makes a lot of sense and I have been told that the QL charger is a bit gutless. I am 75 years of age and enjoy my biking and touring and I enjoy using MRA but this power usage thing has become a bit boring. Nice to get an informative answer rather than been told I have it all wrong and I shouldn't make broad statements. etc .
Incidentally, I have just toured South Africa with friends from Canada and the UK and they all had issues with power falloff. ( quite a broad statement ). I believe I have found a workaround as I would like to keep using MRA. I was just sharing what is working for me. regards.

MRA is still power hungry but it is not as bad as it used to be.
Today i've tried OSMAnd for the first time. This one is also power hungry. Looks similiar to MRA.

Quad Lock has multiple wireless chargers.
One is connected to a usb socket and the other is connected direclty to a 12v source. The last one can charge with higher power.

I use a Pixel 6a. This one always charge slow (no wireless). But still fast enough to keep the battery full.
With MRA as the only app running, the battery stays full. when i play music also, the battery usage is a bit higher than charging. I will loose 1-2% per hour. Some other apps do a better job. But this situation will give me no problems during a day.
So, i'm not complaining but it still can be improved.

Maybe you have a problem with your phone, but I use Osmand when MyRouteApp does not do what is supposed to, i have it on my Samsung S24 Ultra and iPhone 13, but I have no power draining issues ! The device even stays cool while using Osmand in comparison with MRA and drops about 7% battery life per hour.
You should check if other apps are using your location while driving, maybe that's why your battery life is draining faster !

[M. Schrijver]

Flitsemeister is always running at the background. No matter app what i use.
With MRA and OSMAnd, there is little drainage.
With Google Maps, Waze and TomTom Go there is no drainage. Phone is even charged a bit when using one of these apps.

@Adrian-Avram Thanks Adrian - will check.

iPhones don't charge near as fast as Android. I think this is a factor. My Oneplus 12 comes with a 100w charger and using MRA and listening to music it still gains charge at a good rate. Make sure you have a genuine fast charger usb c port and a fast charging cable.

I don't have QL wireless because even on my phone on a main wireless charger you can't get more than 15-20w. So I guess it's the same on the bike. Much slower than a fast charger and cable. Good luck

[Bryn Thomas]

@JP-d thanks - good to know . As I have said I think I have found the solution by supplementing the QL wireless option with a charger plugged into my 12v socket . It just means I have to monitor my phone usage and make choices at coffee stops . All part of the fun .
I like MRA and use it all the time now .
