Sry about my poor english...I got my D2G for about 3 months so far. Overall it is so great for me except a few issues especially the battery life. I just cannot live with watching the battery-level drops every 3 minites.
Well, i heard about that fission performs much better battery life but on fission i cant make outgoing phonecalls so i have to keep on the stock...it really sucks.
Im out of the usa and my carrier is running on UMTS, and i wonder if UMTS drains more battery than GSM...anyway, really getting tired of daily charge. I guess I should show up what i did trying to improve battery life so far and ask for ppl's suggesstions.
Turned off BT, wifi, GPS, 3G when not using them.
Set screen brightness to minimum most of the time.
Removed blurhome.apk, using LP instead.
Removed a lot of bloatwares (including several no-used system service).
Turned off buttton background light (using Adjustbrightness)
Disabled unlock vibration, and weakened visual button feedback (by editing framework-res.apk)
set autokiller to extreme.
Underclocked to 900mhz (quickclock)
Undervolted to 300/13vsel, 550/24vsel, 720/31vsel, 900/39vsel
and this is my battery usage now, no sleeping during this...
Thanks for your time and, appreciate for more advices..
