After shutting down Waze using the double-click, battery consumption was less than 1% per hour.
There is no difference in 'Switch off' or killing it from the task bar. Both functions issue use the same system API to shut down the Waze process. The difference in battery use comes from something else, definitely not from Waze, because with both methods there are no longer any Waze processes running.
Well, today, when I arrived at work at 9:00, before unplugging the phone from the charger, I shut down Waze and manually killed every process in the taskbar...battery at 100%. At 1:00 pm, I checked and the battery was at 98%. At this point, I opened Waze and then closed it using the Switch Off function. At 5:00 pm, I checked and battery was at 80%.
All day long, I didn't use the phone, run any apps, receive or send any calls or texts or take the phone out of the sleep mode other than what I described here.
The logical conclusion is that Waze is draining the battery.
As an iPhone developer, I got curious about this and had a look at my device and on one hand I can assure you that the Waze process is really gone in both cases, but on the other hand unfortunately on my device it wasn't 100% clear if the iOS' location daemon consumes the same after closing waze each way as I have too many applications consuming from the location services.
So there could be a bug somewhere on Waze or iOS that would keeps the location service consuming more when killing waze via menu, but I quite doubt it. I'm not 100% sure because I haven't checked the latest location API's and obviously I don't know exactly what Waze is doing with them, but only know what my own app does and what happens with it.
Besides you need to test it with the same environment conditions. Charge it to 100%. kill all apps and wait some hours. check the battery. then charge it again and open/close waze, wait the same hours and compare the battery.
Draining first 2% then 20% is kind of expected. It's like the gas tanks on the cars, they have 110 to 120% to give you the impression that when the tank is full it takes ages before it the pointer starts dropping to 99%, but then it goes down to 50% and 25% way too fast for my €€€
