So I’ve had the G1 for a good few months now and it’s pretty awesome except for the well-publicised battery issues. Now, I’ve recently started commuting which involves a fair period on the train and tube. Since I started, it seemed to be even worse battery life but I thought I was just imaging it; the battery didn’t seem to last until I got home however, this definitely seemed shorter.
It turns out that for whatever reason, the G1 really sucks when it doesn’t have a signal; it seems to rape the battery when it loses a signal while it frantically polls to find a reception. I installed Locale (a must-have app anyway) and an airplane mode plug-in for it and turned on airplane mode for the times I was travelling. The results are amazing, it literally lasts about twice as long.
Now, it goes without saying that this shouldn’t be necessary, the iPhone doesn’t need dirty hacks to last the day, but the battery issues were well publicised before I bought it. I hope this helps someone with their battery woes.
