Reduced screen brightness — TomTom Community

Reduced screen brightness

Only after disconnecting the Via 62 from connection to the electricity network, does it present in 100% brightness. But as the battery refuses to recharge, this lasts for about 5 minutes.
Then I have to reconnect but - as a result - brightness is reduced to about 50%.

What cab be done to repair this?

    Simply plug the device into the USB socket and plug your lead into the USB Doctor, the device will display the Voltage and Power being used by your various USB devices, when the battery is fully charged the USB Doctor will display 0.00 Amps
    I have one of each type they're only peanuts to buy
    Search Amazon/eBay for USB Doctor

    Hi
    @WillyUt
    I would charge the device for at leat 3 hours then try the same test....
    If it fails again ??? It would seem the battery is incapable of holding a Charge....

    The video will give you an idea of what's involved in changing the battery....

    (Note... The Video is for a Start 62)

    Hi
    @WillyUt
    Welcome to the site....
    The Previous NAV4 and Latest (NAV5 Wi-Fi) devices are quite power hungry and can go into "Power saving mode" if not supplied with enough power
    Are you using the Tomtom supplied cable and Tomtom supplied Power Adapter
    The Charger Adapter and USB Cable supplied by Tomtom WILL run and charge the device at the same time

    Many 3rd parties Mismatched Charger Adapters won't run and charge the device at the same time
    See... It's not simply a power thing.....
    https://discussions.tomtom.com/en/discussion/comment/1182024/#Comment_1182024
    _____________________________________

    When the device is In use they are designed to be always connected to a power supply
    The Tomtom supplied Power Adapter is rated at 5Volts 1.2Amps
    Even after you have recharged the device externally via a mains' charger, when in use in the vehicle, they will still require being connected to a Tomtom supplied Power Adapter (Or a proven suitable 3rd party Power adapter)
    ______________________________________

    (1)... Do NOT attach them to a dashboard USB port in your vehicle as they normally only supply 500mAmp (0.5Amp) and are for data transfer and not supplying power: See... Note (1) & (2)

    (2)... Using a NONE Tomtom 3rd party underpowered or a mismatched cigarette lighter charger can cause the device to go into Power Saving Mode: See... Note (1)

    (3)... On the Models with a built-in SIM, the reduction of power to the SIM can cause the dropping of the traffic info: Note (3)

    Note (1)... At an (Undisclosed) percentage of battery discharge, the device will try to save its power requirements by dimming the screen and eventually powers off the device... Devices with a built-in SIM Card may also lose Live Traffic services
    Note (2)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
    Note (3)... I tried connecting my Tomtom GO 6200 to my Cars USB port, checked the connection status it reports 'Connected over USB' --> 'GPRS (SIM) Disconnected'

    Well, that is an extensive reply! Thank you.
    1) It does not solve the riddle that the display clarity DROPS when my Via 62 is disconnected from whatever power supply (being car cigarette lighter or laptop), although I chose 100% clarity.
    2) I am using a TomTom-supplied cable to connect to laptop / cig lighter. So that cannot explain the issue.

    Hi @WillyUt

    As @YamFazMan has said the unit is power hungry and the output of a USB socket is circa max 0.5amp and the Tomtom Charger is circa 1.2Amp plus. If you were to have your units battery 100% charged prior to use and you connected it to a USB socket , including in a car, the lack of power supply is not sufficient to run the TT device and maintain the battery. Eventually it would turn Off as the battery has run out.

    You can replace the battery yourself, at your risk and it would void any warrantee. Go onto YouTube and input Replace battery on a TT via 62 and you can see what is involved. The batteries and small tool kits are available form Ebay or Amazon.

    Hi, thanks for the extra info. The charge level is currently (while attached to a turbo charger) at 96%. Yet, when I disconnect TT, it immedialtely warns "low level battery". So, I wonder if the 96% level refers to the available supply of power in the battery or to the level of rechargingspeed?

    Hi, it has been recharging (turbo) now for 30 - 40 minutes and the battery finally reaches a decent level on the display. Thus, the battery needs not to be replaced.

    So the basic problem is that the power supplied thru the cigarette lighter is not sufficient to recharge TT decently. Any suggestions on your side?
    Thanks anyway :-)
