How to charge with a higher current?

[yangys]

When using my Toch Diamond as a GPS which is connected to a car charger, the battery will run flat in a few hours. Is there a charger that will charge it with a higher current than 500mA? It is inconvenient for a long trip.

Wait ..... you are saying that your GPS app runs your battery down even while plugged in the car charger?

Mine doesn't do that...

Are you using an original HTC charger?
Some of the generic after-market car chargers output a lower current than what the GPS is actually draining from the phone, so effectively, rather than just charging it, that charger is simply "extending" the time it takes to drain the phone battery.

I'm not near my HTC car charger at the moment, but if I remember correctly the HTC charger outputs 2A.. ie, 2000mA? (can someone correct me if I'm wrong?) And I have no flat battery problems while using TomTom... (The fone does get warm, but that 's another issue that's been discussed previously...........)

Most car chargers only do 500mA

When using good navigation it will pull more than 500mA off your phone, so eventually, the phone will drop dead :) It's true, I have this too.

With an other ROM it can be fixed! Now I don't have this problem anymore. You can also connect 2 chargers parallel but you got to have the possibility in your car. Or you buy a universal USB car charger which can handle 1A. Just like home wall charger ;) (No 2000mA ).


Good luck!

My car chager (with a mini USB output plug) is rated at 5V 2A. My suspicion is that the charge current is determined by the phone, not by the charger. The charger is simply a (constant voltage) 5V power supply. Even if the chager is capable of supplying 2A, the charging circuit in the phone is limiting it to a maximum of 500mA. If the phone is designed clever enough, it could allow a higher charging current though signaling via the two signal wires of the USB plug. Would anyone know if this is the case or not for Touch Diamond? If yes, what would be the signals for higher charge current?

Your idea about using two chargers sounds interesting. Would you be able to give us more details about how to charge one phone with two chargers? Or are you thinking of having two phone and two chargers? That is, after one phone battery gets flat, simply uses another phone.

I have got an O2 Ignito (diamond) I have done an 8 hour round trip using GPS and my battery has not drained... And i do have the original I am using the charger that came with my polaris. my batt always stays full when plugged in and gps is running maybe your charger is what is causing it to drain

Needs a 1 amp charger.
