I’m experiencing super fast complete battery drainage when I have Waze open. Even with the app closed Waze is running in the background. Anyone else experiencing this or have solutions? Is this normal for Waze? Does it really take that much power to run this app? :o
It’s not the app itself. The GPS unit is a huge drain on you battery. You’ll see this with ant navigation app. Recommended to use a charger when navigating for any significant distance
Yeah as an iPhone user myself I can confirm its the same with all gps functions in the phone - invest in an in car charger , personally I have a griffin in car charger with a mophie case and plug the mophie cable into the griffin , it has two slots aswell so handy

Clicking the little sleep button on top of the phone doesn’t close Waze. It will continue to run, even though the screen is turned off, and continue to maintain a GPS signal, which drains the battery. You have to make sure to go into the menu and turn Waze off. At that point, it disconnects from the GPS and won’t use any more battery.
You need to have it permanently connect to an in-car charger - it’s as simple as that. Same with any GPS app for the iPhone. Pressing the sleep button does not stop Waze but does turn the screen off and allow the unit to cool down a bit and use a bit less power.
My in-car charger died today, of course. Didn’t matter since I was getting routing server timeouts anyway (as usual - sigh).
I’ve posted about this before, but I had a more extreme result yesterday…
Most of the time when I drive long distance, it’s near dusk, or after dark. When plugged in, my iPhone will slowly gain charge. If I put the phone to sleep, it will gain a lot faster because the screen isn’t lit up. I tried manually dimming the screen in the iPhone settings, and the charge gained a little faster.
Yesterday, I had to drive a couple hundred miles early in the day, in bright sunlight, no clouds. The iPhone lost 25% charge over the course of two hours (while plugged in). I’m guessing the screen backlighting automatically went to maximum brightness, causing the phone to use more battery than the phone was gaining from the charger.
I’m using a very cheap gas-station knockoff charger, not an OEM Apple charger, and I’ve been told that it doesn’t charge as fast as the Apple charger. I’m going to have to invest in one of those.
I got an apple approved charger from Verizon for mine, it will keep it at 100% while plugged in.

Look for a ‘designed for iPhone’ car charger that puts out 1 amp. Apple doesn’t make one. Check out Griffin, Kensington, etc.
Most of the cheap chargers put out 700 mA, 500 mA or less.
I don’t know the specs off-hand, but I’ve been happy with the Belkin dual USB car phone charger. It keeps two iPhones charging under normal use. It can keep both phones charged if one is running Waze, but it is unable to charge one iPhone while the other is running Waze. That’s a lot of power it needs to put out to do that.
Amperage is not put out, it is drawn
But you can’t draw more than can be put out. Draw or supply, your going to get the smaller of the two.
Typical computer USB port = 0.5 amp
iphone charger = 1 amp
New ipad charger = 2 amp.
I have a new ipad(3rd gen) and a iphone 4. The apple ipad charger charges my iphone quicker then the apple iphone charger. So if you want power, I’d look for a 2amp car ipad charger.
When the ipad is on, it will not charge on anything less than a 2amp charger. It will charge while turned off when plugged into a smaller charger.
picky, picky… :oops:
Remember you can press the power button and the screen goes blank but you still get your audible directions from Waze. Would be nice if it had an optional setting to do that automatically, actually, and switch back on as you approach your exit or some other turn you have to take. That would be good for those routes where you do 100+ miles with nothing happening.
This seems to be common in Android phones too such as the Samsung Galaxy S II. Even with a normal car charger, the GPS drains the battery so much that the charger just slows the drain rather than charges. I think phone manufacturers will have to rectify the issue if people are going to be using resource hungry things like a GPS.
I fully agree about android, my HTC sensation drains battery like… and it warms up a lot when I can keep pluged in when driving
I had to mount it on air vent
I’ve found that Bluetooth doesn’t drain the battery like GPS does. And since the Galaxy S has a lousy GPS antenna This solved the battery drain and the GPS signal issue.
It still gets hot though.
I’m getting overheat warnings on my phone quickly and the charger barely keeps up. What I do sometimes is plug my 120v converter into the cig lighter and then plug in my phone’s AC charger into the converter. I still get overheat quick but much more charge.
I just off the live traffic updates that color codes the roads when you have heave traffic and that has slowed the battery drain. I still need to have it plugged in. But as several have said it is not a waze thing it is anything that uses GPS thing.
Interesting way of doubling your driving points. Cheat! (lol)
I know you’re joking but just to confirm, you can’t cheat by doing this. The server will only allow one user connection at a time so you’ll find either the connection bounces between devices or one is permanently “offline”
