Map renderer - any implications?
  • We can readily see the difference between the 3 map rendering options. Hardware renderer is the most beautiful, with smooth lines and high resolution vector graphics.

    Why are there options for software and software Low Res?
    How many percent does software rendering extend the battery runtime compared to hardware rendering? Or is there no notable difference regarding battery runtime between the 3 options?

  • It never hurts to search the forum. Your question has already been answered more than 4-5 times.
    And if you can't find it directly in the forum, as the search is indeed pretty lousy, you can use Google.

  • good call thx, i shouldn't be shy using Search, you're absolutely right, my bad :|

    Yesterday i did a round-trip to FRA, 6.5h total, and my 4100mAh phone got depleted down to 1% including me switching off the display for 0.5h(total) in between to check if audio instructions would continue in the background (they did/they didn't). relevant (to this discussion) settings were:
    • Brightness: Auto
    • Mobile data: ON / Wi-Fi: OFF / Airplane mode: OFF / Bluetooth: OFF
    • Battery saver: ON
    • GPS: ON
    • Hardware renderer: Software low resolution
    • Night mode: Auto
    • Display always on: YES
    • Navigation map mode: 3D
    Basically i used all possible/realistic settings to keep the phone drainage to a minimum. Once arrived at FRA, i did play with the phone a bit, consuming 5%. Anyways the take home message is, after 6.5h navigation with these conservative settings the phone will be drained. I won't say if this number is good, bad, or ugly, i am just saying. <:-P

    Needless to say, the paper mode runs jerkily and is not suitable for a busy traffic situation with several lanes and multiple maneuvers ahead, i.e. where one needs to react decisively and switch to and follow different lanes within a short time frame, especially when the place is rather unknown. In most other scenarios it is still a very usable mode, I don't complain.
  • I do no longer use my phone anymore in the car for navigation, but I always had it on a usb connector.
    A usb cable to some usb connector almost never is enough to keep the power up when using hardware render.
    Having the phone on the cigaret lighther with a usb connector being able to deliver 1A, it works great.

    (I now have a Joying head unit simply running on 12V. Always on hardware render).

    I did measurements myself and both the phone and the nead unit run about 10 C warmer on hardware render.
  • no problem, in future i'll hook up the phone to a USB power adapter car cable, e.g. the one from my old Tomtom device. i just wanted to learn for how many hours i could do MF navigation with no extra power supply. now i have this number in mind as a personal reference point.

Howdy, Stranger!
