Good morning, seasons greetings and please excuse the cross posting, I would like to know if other users of the superb Birdlog ANZ app are having issues with the app draining their iPhone battery. I have used the app on an iPhone 4S, 5S and now on a 6+, all with the same issue of rapid battery drain. Despite the much larger battery on the 6+, in 4 hours yesterday I was down to almost 20% battery. One of the reasons I bought the 6+ was because of the larger battery. I have put the phone in airplane mode, and turned off location services, but to me the former defeats the purpose of having a phone. I am currently communicating with the Birdseye team to try and trouble shoot my issues. So is this me or is this happening across the Birdlog ANZ user group? Regards Alastair

I’ve never thought of turning the brightness to manual. I guess outdoors in bright sunlight, the brightness might set itself very high. My kids once fiddled with my iPad and set the brightness to maximum. For the next few days until I realised, I could barely get enough charge into it to start each day with as much charge as the day before, let alone charge it fully. Peter Shute Sent from my iPad

I have had reasonable battery life since speaking with the Birdseye team yesterday; turn the brightness to manual and down and also turning off location services (in privacy settings) once the site is selected. eBird.org/content/australia Global tool for birders, critical data for science eBird ACT ebirdact@gmail.com On 19 Dec 2014, at 13:17, Peter Shute < pshute@nuw.org.au> wrote: The 6+ comes with iOS 8, which is supposed to track battery usage.

It might be useful, next time this happens, to check what these figures are. It might just be that you’re looking at the app a lot. It also lists the %battery usage for each app for the last 24 hours and the last 7 days. That might help you work out which app is doing it, although I don’t totally agree with what it tells me on mine. If it turns out that it’s just legitimate usage doing it then you might have to buy an external battery so you can charge it in the field. Peter Shute

Hi Guys, I use the excellent Bird Watcher Diary and it is always accurate on it’s location marks, even when there is no service, and it doesn’t drain the battery of my iPhone too quickly. However, it won’t last a full day of constant survey work (iPhone 4s), so I bought an accessory battery that will fully charge the phone more than 4 times. Allan Richardson Morisset NSW

On an iPhone if you turn on Airplane mode that turns off the WiFi, Bluetooth, and the mobile/cellular radio (which includes the GPS). So in that case there’s no need to also turn off Location Services. If you want Location Services to be active, Airplane mode must be off (the phone will be looking for cell towers). However you can obviously turn off WiFi and Bluetooth if they’re not going to be used (or you can turn them on after activating Airplane mode). But the biggest things which will suck your phone battery are the screen brightness plus 4G. The easiest explanation is that if you’re away from a 4G coverage area the radio will waste a lot of energy looking for 4G towers. In the Cellular section in the iOS Settings app you can easily disable 4G (but you can’t disable 3G/etc unless you disable Cellular Data altogether). If you disable Cellular Data you’ll still receive phone calls and SMSes (but not iMessages which tend to get automagically used because they’re cheaper). I hope this helps at least a little. __ David Burren

OK – but I assume that having the GPS turned on is still a drain as it gets constant fixes – but I must admit this is pure speculation! If what they say is true then I guess you turn GPS on until the app has a fix and then turn it off and see if this makes a difference?

Dave, That was my initial theory too, but I am advised by the Birdseye team that once Birdlog has sourced your location, it no longer uses location services.
