battery life problems

[slimpirudude]

hey guys I'm a little confused,need some advise here. I have used about every rom possible, and have a pretty good idea of what's good battle life for my phone and what isn't..lately I have been getting awful, even compared to people with same phone and same rom. I am not sure why, I've done everything I know to. this happened on miui , liquid, cm7, gb stock, and now hexen froyo..is there something I'm missing or what's the deal? Its weird to get less than half what others on exact same set up are getting...

EDIT:::::: I have now noticed something that might be useful info for someone to help me out with... when I charge to full and let it discgarge, everytime it gets to 70 something it jumps down to 30 something. Then when it dies (atleast once a day) and I recharge it it gets to 30 some and jumps back up to 60 or 70 something...I have calibrated with the battery calibration app and tried it a second time next day with the battery calibrate app...any idea how to fix this????? It doesn't explain why I lose battery so fast, but it is still another big problem I have with battery aswell. So if anyone can help with either (or both!) issues please let me know!!! Im up for suggestions..

Here's a battery writeup I did a long time ago. You probably already know all this stuff, but it may jog your memory:

Battery Life

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. Or, "Get rid of widgets that update automatically. Add a shortcut to the app instead". It takes just as long for the app to open as it does for it to update.

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.

Was checking out all the steps you outlined for max battery life, with the gb update I can find the battery use one, where it outlines what is using you battery the most. Any help would be appreciated. Thanks.
