    I just got this phone 2 months ago and lately for no reason it has been draining like crazy. I had got it to start lasting for 36 hours at some points before the battery got low and now out of no where its started only lasting like 8 hours. I haven't been using my phone anymore so I don't know what the problem is. Take last night for example. I charged the battery till it was FULL and pulled it off the charger at maybe 1 am. I used it to text a couple times and talked on it for like 2 mins and went to bed sometime around 5. I woke up at 3:30 and it's dead. This might be acceptable had I been using it but the thing has been completely idle for the last 10.5 hours! How could the battery be draining so fast? Especially when it wasn't before? Is my battery broken somehow?

    EDIT: Also I'm even using SETcpu to clock my phone down to 600 MHz when I'm not using it (aka screens off).

    Check your battery usage and see which apps are always on or draining, it seems like maybe a bad app doesnt shut down...hopefully

    I think that 8 hours is actually average for Droid 2 Global users. This doesn't sound like an actual problem. I have never heard of this phone holding a charge for 36 hours, unless it was mostly idle with the screen off the whole time. I think that the eight hours is a more predictable battery life given normal usage. This has always been a power hungry phone.

    As an aside, I did have my original battery replaced under warranty, but I was getting 1-2 hours, not 8. Now my standard battery gets about ten hours, while my extended battery gets 15-20 hours.

    If you are ever in areas of low or no signal, that will drain the battery faster than anything.

    I didnt notice that this was a d2g thread!

    Yeah wow, I have NO idea how you could manage 36 hours, even with very light use. When i first got the phone it couldnt last for 10 hours to save my life, even with juice defender set agressively, syncing and auto-update widgets off, and brightness low.

    It took a lot of tweaking, learning and usage habit changes to get me to last 15 to 18 hours with the extended. Now I can get it to play music for 14 hours before dieing!

    Sounds like a new app is causing an issue to me.

    I was just going to suggest this! I had the same deal, I am able to keep my phone going for about 18 hours with light use, 10 hours on an average work day. Then my phone started dying in about 6 hours... couldn't figure it out!
    Turns out I had been in a low signal area, the phone asked to switch to Global, and I forgot to change it back.


    Anyway, good luck!

    Glad you found your problem. Here's my generic battery saving tips:

    [FONT=&quot]Battery Life[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]Here's my tips (Individual items may not apply your phone):[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]1. Go to settings/wireless & networks/mobile networks/Enable always-on data. Uncheck always on data. Your phone will still receive email, text, & phone calls as before as well as internet usage but your battery will last a lot longer.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]2. Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail. Go to the Google Gmail inbox on your computer and log into the Gmail account. On the top right of the screen is an option called Settings. In there is an option to have the Gmail program poll your regular, non-Gmail accounts (From the inbox; Settings/Accounts & Import/ Check mail using POP3). Provide the email address and the password. The Google Gmail program will then poll your other accounts on a frequency from 1-5 minutes and push the email immediately to your phone. The polling frequency is determined by each account's activity - more emails = faster polling. This saves battery power because on the android OS pop3 accounts are polled at a frequency of 1-30 minutes and that really eats battery. Because the phone goes and checks those accounts for mail whether there is mail there or not.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]3. If you are using Live Wall Papers, stop![/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]4. Use wifi any time it is available. It uses a lot less power than 3G and it is much faster.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]5. If there are widgets that automatically update (facebook, weather, etc.) change their update frequency in their settings menu. Set them to 30mins or 1 hour.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]6. Oh, almost forgot, get the extended battery from Verizon.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]7. Turn off the GPS unless you are actually using it. There are some background apps that can burn a lot of power via a live gps.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]8. The Power Control Widget is a good tool for easily turning on and off some of these features (gps, wifi, screen brightness, etc.).[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]9. From the home screen do the following: menu/settings/About Phone/Battery Use. This graph will show the 10 biggest power users on the phone. It should always be Screen as the top user and the android os, android system, phone standby and phone idle should be the other top users. If there is an app listed you should determine if it’s an app you actually use a lot or do you have a rogue app that needs to be uninstalled.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]10. Get Screebl. It will turn your phone off anytime you are not actively using it.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]11. If you have either a task killer or an anti-virus app installed, you should uninstall.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]12. Go to data>system>and delete batterystats.bin after you've charged your phone to 100%. This will help with battery meter accuracy.[/FONT]
    [FONT=&quot] [/FONT]
    [FONT=&quot]13. D2G - go in to settings, wireless and networks, mobile network and change the network type from global to CDMA only. The d2g is locked out from using the local GSM networks in the US. You don't need global radio turned on in the US just overseas. Go into Settings > Wireless & Networks > Mobile Networks > Network Mode > and turn off the default setting of Global and turn on CDMA. This assumes you are in the US.[/FONT]
    [FONT=&quot]14. If you have ad blocker, turn it off.[/FONT]
    [FONT=&quot]15. If you are using Launcher Pro, try switching to ADW or Zeam for a while.[/FONT]
    [FONT=&quot]16. Reboot you phone every day or two.[/FONT]
    [FONT=&quot] [/FONT]
