Today I turned on my 3597 for the first time since 14 Aug 2020 when I last updated the map.
It wasn't long before it warned me that the battery was low (less than 50%). Haven't had a need for it since we have been hunkered down at home, so it hasn't been charged since the last map update. I always use the power button to turn both my units off since Garmin suggests that to conserve the battery and it also reduces battery cycles that heat up the battery.
Turning on the Nuvi 660, the battery indicator showed that the battery was at 100% (or close). The 660 does have a longer lasting battery as it definitely stays on longer when disconnected from a power source. It may also have less battery drain when completely turned off.
So, if you haven't used your GPS in a while, check the battery and charge it if necessary! Avoid having to wait for it to charge if you need to use it outside your vehicle.
I am mistaken, there are two ways to shut down a Garmin.
1. Just use the off button
2. Hold the off button and wait for the message " Do you want to turn off?" Then click "Yes"
The manual for the 3597 states
Turning Off the Device
1. Hold the power key until a prompt appears on the screen.The prompt appears after five seconds. If you release the power key before the prompt appears, the device enters sleep mode.
2. Select Off.
So metricman is likely putting the 3597 into sleep mode and yes the battery will be discharged after a few weeks.
The 660 doesn’t seem to have a standby mode, just a quick push of the button shuts it down.
My 2460LMT sits in the car, plugged into a USB built into the dashboard. The USB is only powered when the car is On or Acc. When I shut off the ignition or go to Off, the Garmin warns that power is lost and it will turn off in x seconds (10 or 15 IIRC).
I just let it do that. Haven't had any problems.
I do notice that when not used for a few days, it takes this model a LONG time to initially find satellites. Sometimes about 5 minutes, even with unobstructed sky.
Nope, I hold the power button until I get a "Turn off the device" prompt and then select select "Off". I knew that Standby" would eventually drain the battery thanks to a post here.
Actually, a quick push of the button on the 660 takes you to the "Audio Output" screen. It's a quick way to be able to turn the volume down when needed. Removing the power will also cause a "Turn off" prompt on both models and it will shut down anyway after 30 secs. The 3597 does a similar routine when power is removed but it will go into "Standby" after 30 secs instead of "Off" if you don't select anything.
I get a low battery warning from time to time even though the unit has been connected to vehicle power, sometimes for a long trip (spanning hours). Figure the internal battery is probably on the way out. I normally don't put the device into sleep mode, rather follow the steps to turn if off. On the 2598 the options to manually put the device into sleep mode or manually turn it off.
Entering and Exiting Sleep Mode
You can use sleep mode to conserve battery power when your device is not in use. While in sleep mode, your device uses very little power and can wake instantly for use.
TIP: You can save power by putting the device in sleep mode while charging the battery.
Press the power key.
1. Hold the power key until a prompt appears on the screen.
The prompt appears after five seconds. If you release the power key before the prompt appears, the device enters sleep mode.
2. Select Off.
Thanks for that info
Even if not in use, the battery still discharges it self over the course of 6 months!
I forget the exact model, but I was looking (online) at a Garmin, 7-inch screen, that had by spec only a 30 minute battery life. I personally would not have issue with that as I understand they are attempting to reduce weight. The weight of the device sticking off a windshield causes vibration.
