tomtom go 300 battery problem?

hello all.

not sure if this is a battery problem or even a problem at all. if i dont use my tomtom go 300 for 3 or 4 days, then it wont switch on again until i have it on charge for about 15 minutes. then to get it to switch on i have to hold down the power button for about 5 secs, and it looks like it is re-booting (with a progress bar) and the tomtom logo appears. everything then works fine.

this happens if i leave it in a fully charged state or not.

but, when it is fully charged, i get about 5 hours continous use out of the battery, which implies that the battery is good.

is this normal?

thanks.

Holding down the Button for 3-5 seconds is not unusual. It's to save inadvertent switch on. If the battery is flat, it will have to do a Full Reboot, which takes a little longer.

I would not have expected the battery to drain in less than a week. When these things used to be talked about I think it was 2-3 weeks.

I would expect about 5 hours use on a full charge.

From your description I would say that the battery is good, but an internal component is drawing too much current.

thanks for the reply.

switched it on today after a couple of days and it came on ok, showing full battery. its a minor irritation rather than a huge problem, so i'll live with it for the moment.

regards.

Well, I still have my TomTom Go 300 6 years on. I thought I'd have a go at replacing the battery with a higher capacity one, although to be fair the original battery was still working pretty well.

After replacing the battery, the unit is working fine but I still have the existing problem with the battery going flat after a couple of days, even when it is switched off (and the sd card removed for good measure).

I have just acquired a genuine TomTom wall charger. My next question is - for long-term battery life is it better to keep the unit on charge all the time, or keep re-charging it every few days after the battery has gone flat, or not worry about it and just let the unit sit for months on end with a completely flat battery and then charge it when I need to use it? To be honest, the original battery seems to have lasted pretty well adopting the last method.

Thanks.

Oh, if only TomTom had continued making good units after they changed from the 300 series. Crying

If you've kept it going for 6 years, you don't need any advice from me. Sounds like the second method does well enough for you.

Thanks for the replies. The TomTom Go 300 does everything I want it to, so I have never really felt the need to replace it.

Just press the button inside the tiny hole with a suitable blunt-ended pin for half a second or so. An unfolded paper-clip is perfect for the job. Try not to use anything with a sharp point, as it will eventually damage the switch inside.

Yes, that's right.
Though you can do it when it's switched off too, as it's normally only "sleeping".

I've tried this and the unit turns off as soon as the pin is pressed which is fine. Unfortunately the battery still goes flat after less than 24 hours, even though the unit is obviously fully off. I assume there must be a permanent short on the battery somehow (and always has been). The strange thing is the battery life with the unit in operation is still good - several hours at least, although I haven't tested it to the death. I shall just carry on using it as before until such a time as it dies completely.

Thanks for the help.
