Finally, I received my brand new G1 (dev edition) yesterday morning. It was love at first sight, even with some sentences for the memory I won’t tell here. Anyway I like it, so here you are some advices to make the battery last longer:
1.- Delete all APN you are not going to use (in my case, all T-Mobile access points).
2.- Turn off Wi-Fi, bluetooth and GPS unless you need them.
3.- Use only 2G networks if you do not need 3G.
4.- Screen brightness is fine at 25% (at least for me).
I tell you more when I have enough time to play with my new gadget.
By the way, it cost 430â‚¬.
