    Is outstanding.

    Excellent job. Vast improvement over 5.4 and what I suspect was some problem in the CM7xxx base. 5.5 is operating flawlessly.

    Mine is HORRIBLE, again. Minimal use and I'm lucky to get 8 hours before it needs charged. Wish I were getting the results you guys were.

    My phone is idle - but I'm still sitting at 90% after 24 hours on battery ... I do not have ANY apps installed however - I very much suspect it is one of your apps. I bet if you could go on a reflash with no apps, you'd see very different results.

    If 5.5 is superior to 5.4, then will I look forward to several days on a charge if I bump up? LOL! Just switching from CM7 to my current SS 5.4 got me to where I can now get 18-24 hours, depending on usage...one day with nearly no usage, I was at 60% after 24 hours. That was a jaw-dropping improvement for me as before, I was lucky to get 9-10, usually around 8.

    Here's a battery saving list I wrote about a year ago, but some it may help you. Good luck.

    Here's my tips (Individual items may not apply your phone):

    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.

    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.

    3. If you are using Live Wall Papers, stop!

    4. Use wifi any time it is available. It uses a lot less power than 3G and it is much faster.

    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.

    6. Oh, almost forgot, get the extended battery from Verizon.

    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.

    8. The Power Control Widget is a good tool for easily turning on and off some of these features (gps, wifi, screen brightness, etc.).

    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.

    10. Get Screebl. It will turn your phone off anytime you are not actively using it.

    11. If you have either a task killer or an anti-virus app installed, you should uninstall.

    12. Go to data>system>and delete batterystats.bin after you've charged your phone to 100%. You should let your battery deplete completely, then charge it up to 100% again. This will recalibrate your battery for your current setup. It’s a good practice to do this with any new ROM install. If this doesn’t work for you, then it may be time for a new battery. This will help with battery meter accuracy.

    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.
    14. If you have ad blocker, turn it off.
    15. If you are using Launcher Pro, try switching to ADW or Zeam for a while.
    16. Reboot you phone every day or two.

    Chevy - I cannot go without using apps as this would defeat the purpose of Android? :)

    BayouFlyFisher - The Data enabled was checked in the wireless settings. Not sure if not using that will have negative results. I don't use POP3 accounts, only Yahoo and Gmail. I never use live wallpapers. I do try to use Wifi as much as possible when available. I don't have any widgets at all. I do turn off the GPS while not in use and use the lowest setting for the brightness. The only app that is updating in the background is WeatherBug and the frequency update is set to 1 hour. I did delete the batterstats.bin just now with root explorer. I'll let the battery drain and see if that helps. I don't use task killers or antivirus apps at all. Never have. The biggest offenders using the battery are the ones you listed, in almost that order. The OS isn't using more than 3-7% typically.

    I did flash a higher voltage kernel this morning as well. I was using the stock lowV1ghz. I went with a medV1.25ghz this time around. I typically keep the processor on max 800 and min 250 with the on demand governor.

    If this doesn't help I may just need to buy a new battery. It's been just over a year on this one so far. I appreciate the feedback and advice! Thank you. I'll let you know if any improvements are made.

    The apps I use are:

    MyTracks, MyVerizon, QuikPic, Redbox, Root Explorer, Scanner Radio, Swype, Google Music, WeatherBug, Yahoo Mail and Gmail. Google+ and Facebook, Chase Bank, Alarm Clock Plus, Amazon App Store, and History Eraser. Maps, MMS, Google Voice, and the tether apps that are built in (hardly ever use those). ADW EX is my launcher app.

    I don't play games on my device either or have any downloaded. I try to keep my apps minimal in order to save the battery.

    I don't use all that many and can't imagine any of those eating up the battery to the extent it does.

    LOL, of course ;) I am just trying to narrow down the issue. In other words - if the problem goes away, we know it is an app that is causing the issue. At that point, it's just a matter of tracking it down. If the problem does NOT go away, I know it's specifically in my ROM and I know where to start looking. My suggestion is certainly not meant as a solution.

    Alternatively - run mtop in terminal when it seems to be sucking juice - it will display a list of top apps - anything power hungry will show at the top.

    Do you think this will work for the extended life battery? Been getting 40+ hours on the extended battery but the problem is that the phone still doesn't read the battery correctly. The battery icon on the status bar will get to 5%, I'll reboot and it will go back to 90%, later on in the day it will go back down to 5%, I'll reboot and it will go back up to like 70%. No amount of calibration I've done has fixed this.

    How do you shut that mtop thing off? I just ended up resetting the terminal from the menu and then killing terminal emulator with a task killer to make sure. There must be a better way. (sorry Google isn't turning anything up on it)

    All you have to do to stop it is exit the terminal.

    mtop is a script I wrote - it is an endless loop. Just 'reset term' from the terminal menu ends the terminal app AND mtop

    I know, I'm just busting your chops :) I'll see what mtop says and let ya know. Since flashing the MVkernel I'm about 2 and a half hours in and I'm down to 80% battery life. Not sure that's considered good battery life. Display is at 39% next is Phone Idle at 12% followed by Cell Standby at 11% and Wifi at 10%.

    Not sure if this will help you but worth a shot. Do you see anything in there concerning?

    Ha ha yea I figured that ;)

    OK - I see a problem in that screenshot - system_server. What else is running as far as apps? Try a hotboot (from power button menu) and try mtop again

    I have a system_server as well, but it jumps from 0-2% CPU utilization over the course of 3 min.

    What does it mean? I have system_server running as well. My battery life is ok. Around 40h. I'm running low800 kernel set at 125-600.

    system_server in itself is not an issue - but ongoing usage like I see in that screenshot is ... it is a necessary process
