    Thanks AngDroid. Where can I get this SIM card fix? (Nevermind i see it is in the fission rom manager, just installed it and reboot the phone it says "sim card detected. Setting network to global". Not sure why it did this but i set it back to cdma/evdo...

    I will try this battery conditioning I guess but I didn't think these newer batteries needed such treatment...

    my network was already set at cdma/evdo so that didn't help.

    I use jrummys droid overclock app to downclock my cpu but did not notice any improvement in battery life...

    Yesterday I got 6 hours from the time I unplugged it until 10%. According to Battery Manager, the screen was only on for an hour. BT, WiFi, Push and GSM were all turned off the whole time, and I was mostly messing with my homescreen layout, using the Droidforums app and a bit of Evernote. I'm using LauncherPro Plus and the Simi clock widget with weather and the battery indicator turned on. Otherwise it's stock and unrooted.

    Last night I charged it fully, and within two minutes of unplugging it, it was down to 90% battery. I yanked the battery (thank god I can finally do that, eff you iPhone :), waited a few minutes, and put it back in. Frustrated I put it down on the counter, unplugged, and went to sleep. This morning I woke up to the same 90% battery I had last night, and now, six hours later with moderate use (45 minutes with the screen on, 15hrs since unplug), I'm at 60%. I'll keep an eye on it, but that might (fingers crossed) be a fix of sorts.

    First day at work with the D2G. Listening to MP3's of the Howard Stern Show for 10 hours via Bluetooth speaker, 30 mins of surfing web, a few calls/txt msgs, Phone on for 12 hours on extended battery went from 100% to 50%

    With my Droid 1 standard battery same usage I'd get 9 to 10 hours on battery 100% to 20%, and most days I'd change to my second standard battery.......

    both phones were/are rooted
    D1 Chevy01 SS rom 1.0 low V kernel
    D2G Fission rom

    ~22 hours so far since yanking the battery last night and fully charging it. It's reading 40% right now :D Only used it about 2 of those hours today, but it sure beats 5 hrs of standby and 1hr of use. Sweet! Hope it keeps up.

    I dont know what rooting the battery means. But my battery sucks and is always dead. If I ever get stranded, I wont be able to make a call to save my life. I have the battery it came with. It says extended. Is there another one I need?

    @Steeda: Try this:
    1. Charge your battery to full
    2. Unplug the phone and remove the battery
    3. Wait a minute or two, and replace the battery
    4. Turn off Wi-Fi, Bluetooth, Push Email and GPS, and turn the brightness down to the lowest (all of these settings can be found in Power Control which is a stock widget that should come with the phone).
    5. Go to settings->applications->running services and see what's there... I killed Skype and Sync Service (tap the service and hit "force stop"). If Blockbuster and Amazon are in there, you can kill those too.
    6. Go to settings->battery manager->battery mode and check to make sure it's on Nighttime Saver
    7. Run your battery down to 10% (hopefully will take 20-someodd hours now), and then charge it to full again.

    See if that makes a difference... those steps made my battery life go from 6 hours of standby to well over 24. I was playing with adding apps last night, so I accidentally started USB charging it after 20 hours of standby, but the battery was down to about 40% before plugging it in.

    You root a phone, not a battery :D It's pretty easy and gives you access to settings that you didn't previously have (including installing certain applications). I just did that last night and I'm now going to look into removing some of the stupid bloatware apps that came with the phone to increase the battery even more. All the steps above were done before I rooted the phone.


    You can always turn on BT, WiFi, GPS and Push as needed -

    Well, I'm still getting rather poor battery life... Maybe 6ish hours with very light usage.

    I'm going to cycle the battery from fully charged to 0% a few times and see if that helps.

    Pardon me, I'm new to Android... With an unrooted phone, if you just kill running services, it doesn't seem to do anything beyond killing them for that session. In other words, I power off and on, and Skype and the News retrieval service and others that I previously killed are back and running.

    So, if I root, will it allow me to go in and kill the bloatware permanently? I'm also getting lousy battery life, even though I got the Motorola extended battery. I can get a day out of it, but only if I don't play with it much.

    The other issue I see with killing bloatware is knowing what is bloatware and what might do something I care about. Is there some place that has more detailed descriptions of what a particular running service does?

    i use my D2G moderately, occassional facebooking and twittering through the day with calls and texts as normal. i get probably close to 14 hours battery life with the brightness all the way down and all gps and stuff off. i would say its substantially right

    I'm currently at 8:15 uptime since my last full charge, with 2:15 minutes of screen-on time. My brightness has been at 50% for most of the day. This seems like a more reasonable battery life than what I have been getting, however this has been with light usage, and the CPU downclocking to 600MHz max with the screen off.

    I'm going to cycle the battery a few more times to see if I can get it up some more. Any more suggestions?...
