mobile phones charge!

[gavroche]

Set up my endomondo before my 40 mile ride but the phone packed up after 30 miles (flat battery although it was fully charged beforehand). We did stop a few times on the way which obviously didn't help. I think the phone would last possibly 40 miles on a non stop ride. So be aware. Luckily, I also had the bike computer as back up for mileage.

Once you turn the GPS on the batteries drain in no time. The older your phone gets, the worse the problem becomes.

One of the reasons I bit the bullet and went for a Garmin Edge.

Receiving and processing GPS signals, together with the data downloads and handling, toasts mobile phone batteries in very short order. Although, unless you've got an iphone, buying a second battery is pretty cheap and, when you see how small they are, you understand why they drain so fast.

Is it an android? If it is go to Home->Menu->Settings->About phone->Battery user (or something similar). Turned out my phone was using nearly as much battery as the GPS (ok, crap receiver) so I turned it to aeroplane mode, and the battery was at > 60% after 45 slow miles and a dinner break on the FNRttC - and it's a notoriously tiny battery.

This ^^ is a good point. Oone of the apps that I use most frequently is Power Control. It gives me 5 buttons on screen that allow me to toggle bluetooth, wifi, updates, GPS and auto lighting. It's frequently used when I know I'm going to be away from power to preserve the battery. The updates, especially, can take a lot of juice, depending on which apps you have installed, downloading news, weather, train info, facebook etc etc.

The other one I use is Advanced Task Killer, which will stop any running apps just in case you forget to turn off Maps or Music or whatever.
