Battery drain when navigating

[Flat Twin Therapy]

@Rob-Verhoeff Thanks Rob, good to hear it is being worked on.

No I'm not using 3.2.8-151.
In the app version number states 3.2.8-150

How do I update? In the play store no update is available

Had to go somewhere tonight by car. Phone in a wired charger and normally indeed positive charging. Now, track recording and navigation: 2 crashes and negative charge. When I stopped navigating and kept recording track, positive charging, so issue is reproducable.
I do know you mentioned latest version might fix battery usage, but still wanted to inform that navigating seems to cause it, not the track recording.

@Rolf-Aalders 3.2.8 is the latest! Android and iOS have a slightly different build number (150 vs 151).

Reading these messages it indeed has more to do with the navigation rather than the background tracking. We’ll investigate!

@Corjan-Meijerink thanks!
Let me know if you need more info! Happy to help!

My contribution to the topic "battery charging". I drove a short distance today with the bike and Navigation Next. At the start I had a battery charge of 73%, at the finish was 64%. The route is 3.4 km long and of course only takes a few minutes. Equipment: iPhone 13 pro, iOS version 16.3.

Also tested battery drain this morning on my OnePlus 6T with Android 11 and MRA Next 3.2.8-150 installed. A half hour 25 km tour (no tracking) dropped the battery level with 9% without charging.

@Mopetenpit @Arno-0 Now that’s a significant different between you two. I would like to say that the Android experience is more or less reasonable battery consumption. The iOS usage is however more than you would expect.

Its exactly what I experienced. Large baterry draining despite phone on charger (you have my report)

I plan today to do 150km, I will reset all the counters and start with 100% battery and on charger. Will post results

Today no navigation, but onbly tracking a route by bycicle. Let the screenshots speak for itself.

Started tracking at 96% battery capacity. Distance 15km; time 40minutes.

Halfway, 1% background activity

After 30km's end of tracking. 90 minutes pause in between two trackings and only 3% use of background activity.

Batterycondition is 100%.

Looks good so far. Resumé: tracked with the app for 90 minutes and stood on standby for 90 minutes.

iPhone 13
iOS 16.3.1
App-buid: 3.2.8 - 151

@Rob-Verhoeff That's very decent! Thanks for sharing the information

Première sortie à moto avec la version beta :

Samsung Galaxy S21 FE 5G - Android 13 Batterie 4.500 mAh
Version beta 3.2.8 - 150

1° sans alimentation du smartphone
Démarrage à 10h à 100% avec uniquement un itinéraire + suivi + Bluetooth écouteurs : Batterie vide (0%) à 12h !!!

2° Essai avec alimentation :
Démarrage à 14h30, batterie à 58% avec uniquement itinéraire + bluetooth écouteurs : Batterie à 44% à 15h30

Effectivement, la batterie se vide à une vitesse VV' alors qu'en utilisation normale, la batterie tient plus de 2 jours.

Je suis certain de ne pas tenir toute une journée malgré l'alimentation 12V.
C'est un réel problème que je n'avais pas avec la version MRA Navigation.

Bon travail et bonne continuation, on compte sur vous

@Willy-DEOM Thanks for sharing the feedback and further information. We will continue investigating the issue.

@Corjan-Meijerink Just been on a run today with my iPhone 8 Plus (iOS 16.3.1) and there was no drain on battery whilst tracking, navigating and screen recording. Indeed, the charge increased to 100% as the ride went on. I was using a cable from auxiliary socket to the Lightning Port to charge and i will check wireless charge performance on the bike next time I am out on it. No issues with drain from my perspective.

[Corjan Meijerink]

@Dave-J-0 Thanks for confirming another side of this issue! I just drove for 45 minutes with full screen brightness, tracking on and using the nee navigation.

Battery usage was 15% which is pretty decent. When using Google Maps this morning during a 35 minute ride, the battery usage was 11% which is very similar.

My device is an iPhone 12 Pro Max.

@Corjan-Meijerink
Indeed that sounds acceptable! I don't mind the battery use when not charging. But when charging there should still be a positive charge, else the risk of running out of battery during a ride is too high. That should not be the case, right?

[Corjan Meijerink]

@Rolf-Aalders That indeed really should not be the case!

@Corjan-Meijerink here my battery usage today. Used MRA between 7:30 and 9 and 4:30 and 6. My battery doesn’t like cold weather and this morning was ccccolddd (1 degree Celsius and fog). I think this is ok. My phone (iPhone 7) is always on the charger when driving. I do have background location set to “when using app” because I noticed several crashes when not even using MRA and quite some battery usage.

[Corjan Meijerink]

@Evert-Kuiken This is fine indeed!

Yesterday I did cca 150km in car with charger. Battery stayed on same level. Didnt fall but didnt charge also. Improvement from last version, however charger is still mandatory

@Corjan-Meijerink Any progress on this topic?
