Hi Allan, Andrei, Just a couple of comments: 1 - The concept of "high power method" is ambiguous, which are those high power location providers? GPS? Nowadays, there are GPS receivers that consume just 1 mA. (http://www.air-semi.com/media/pdf/AIR_firstcustomersrelease_FINAL.pdf) On the other hand, CellID or WiFi data has to be translated into lat/long by invoking some Web Service. In case we are using a mobile phone this could suppose a certain impact in battery life. I mean, with these next generation GPS receivers the concept of low power method to retrieve location is not clear. How is the UA going to decide this? 2 - In any case, If I have a mobile with a GPS (or any other hardware) consuming a large amount of energy, I think it wouldn’t be acceptable that it would be switched on just because I am browsing a certain web page with the “enableHighAccuracy” attribute set (or “lowPowerOnly=false”). I would prefer to have this parameter removed. I think that the way of retrieving location should be specified by users in the UA user interface, in the same way (as an example) that GoogleMaps Mobile does with the “use GPS” option. Cheers, Angel
