Waze battery consumption

[postman007]

Just picked up that Sony/Ericcson charger.....Pretty well made......Waze does drain that battery...But its still great

I solved the problem keeping the kernel at 1.2 Ghz

In that way I can use waze about 7 hours with a battery drain no more than 2% in total

In these condition I can even recharge my fone when waze is on

My previous kernek was 1,5 Ghz and was draining battery in an incredible way

Just curious how you change the kernel to 1.2 Ghz. I guess you need quite detailed info about android that not everyone has?

Switching off 3G and using only 2G can help preserve battery life.
If you don't need to see the screen, you can turn off the screen too.
Also, turn off WiFi when you don't need it.

You can put screen at about 20%...

Even with the screen off most of the time I can hardly drive 8h with waze running.

From experience with my old HTC Desire, I disabled WiFi/Bluetooth and my phone charged 1% every 40+ mins. Otherwise it discharged from 100% to 20% in 2-3 hours with WiFi/Bluetooth enabled and a standard in car charger connected

Now with my new Samsung Galaxy S3 and the standard larger 2100 mAh battery It will happily hold its charge while connected to even the cheapest in car charger, although I still turn WiFi off to decrease the battery heat while GPS/Bluetooth are also enabled.

If your without an in-car charger at hand or want to reduce the load from a standard in-car charger I suggest the following:

Disable WiFi and Bluetooth
Change the display brightness settings to low or auto and use a black background
Turn off synchronize for emails, social networks and updates etc. Or increase the update intervals to >30 mins
Enable "Power Saving Mode" in Settings (ICS 4.x.x only)
If you have an HTC or a device that has these settings hidden, install Hidden Settings to unlock the hidden Power saving settings

Try a third party Battery/performance App:
Android Assistant
Easy Battery Saver

Battery heat can also lose charge quicker or even damage your battery. Try to keep your phone off the dashboard away from direct sunlight and at room temperature. Position your phone in the shade or over a heating vent with cool air flowing.

Not for the feint hearted
Finally Root and install a custom Rom/Kernel which supports better power saving (disable/limit CPU cores etc)
