Extend your battery life, Extend your performance​

Knowledge is power, please read all 4 posts (including hidden info... It keeps everything organized) of the OP thoroughly.

You need to run a couple battery cycles before you will see the full results... Some people experience very bad battery life on their first cycle, let it settle in.

TROUBLESHOOTING/BUG REPORTING

Q - I flashed the ROM and now I have an issue, what should I do?

A - Don't freak out! Pull a logcat and paste it on to pastebin and provide me a link in the thread to it. Along with the logcat, please provide me with as much information as possible. Things that you would think could help me fix this issue.....i.e what you flashed, what happened, what did you do prior to the bug/issue.

PLEASE INDICATE WHICH VERSION OF THE ROM YOU ARE ON.

Q - How do I pull a logcat?

A - Check out this thread http://xdaforums.com/showthread.php?t=1726238

Q - Do I have to wipe before flashing??

A - YES, even if you're coming from a previous version of this ROM. By doing a full wipe each time, it not only avoids any issues that come from not wiping BUT if you report an issue, I then know that is a legit problem and not because of lack of wiping.

Q - I see (Insert developer name) has fixed this or has added this feature, are you going to do the same?

A - NO! No disrespect to that developer but I have not and will not keep up with what other developers are doing.

Check the ISSUES section below before reporting anything. Also check post #4 for workarounds and fixes.

- Some settings in Aspire Launcher force close (nothing that effects usability, working on it)

-DO NOT use lockscreen controls in Noozy settings. It will glitch and open straight to home screen. (No lockscreen)

-Netflix- workaround in post #4 confirmed working

- Copy and pasting a link from bookmarks causes browser to FC

-You tell me

1. Download ROM and GApps

2. Place ROM and GApps on SD

3. Reboot into a safe recovery

-EL29 Direct Boot http://www.rwilco12.com/downloads.p...ernels/Recovery Kernels/GB/Noobnl Direct Boot

***Note: YOU CANNOT FLASH MODEMS WITH EL29

-EL26 http://www.rwilco12.com/downloads.p...ernels/Recovery Kernels/GB/Chris41g/Stock CWM

4. Wipe Data/Factory Reset and Dalvik Cache (in advanced settings in recovery)

5. Flash JB Wipe All x2 zip

http://xdaforums.com/showthread.php?t=2077277

6. Flash ICS Modem if not already on one (any of these will do. FL24 and FI27 are the newest ICS modems)

YOUR DATA WILL NOT WORK ON GB27, GB08, GA10 OR ANY OTHER JELLY BEAN MODEM. YOU MUST USE AN ICS MODEM FOR YOUR DATA TO WORK!!!!!!!!!!! AND GUESS WHAT THEY'RE ALL LOCATED BELOW... CLICK THE BUTTON. And there really is no "best" modem to use, most have little difference between them... Please refrain from asking, try them and see what works best for you. Everyone will have different experiences.

How to Update Profile and PRL:

YOU MUST DO THIS AFTER FLASHING A NEW MODEM TO ENSURE YOU HAVE DATA AND MMS WORKING.

First, make a backup of your current ROM. Then you need to get on TouchWiz ROM. Doesn't matter which, then wipe cache and flash the modem ( do it again if you've already flashed the ROM), then update PRL AND PROFILE. It will reboot itself. Then restore your backup and you should be good (or flash the ROM if you are doing this in the right order).

7. Flash ROM

9. Reboot (it takes a few minutes to boot, be patient)

10. Extend

***Note: I highly recommend using the Autostart Manager in ROM Toolbox to get rid of widgets and other features of apps you don't use to extend your battery life. Remember the less that is running the more likely your phone is to go into Deep Sleep (much like people lol). Just be sure to make a backup before you start playing with settings you aren't sure about. Anything with widget in the title is OK to disable (if you don't use the widget). If you don't do this you can have widgets you aren't using updating in the background, who wants that? And most apps have widgets anymore. If you press menu you can also have it show system apps too.

BATTERY LIFE DEPENDS ON THE USER USING THE TOOLS PROVIDED IN THIS ROM (and below in the Extras section). IT'S NOT GOING TO DO EVERYTHING FOR YOU. SCREEN ON TIME AND A VARIETY OF OTHER FACTORS ALSO NEED TO BE TAKEN INTO CONSIDERATION AS WELL. IN THE END IT IS UP TO THE USER TO MAXIMIZE BATTERY LIFE, NOT THE ROM. IF YOU ARE HAVING SEVERE BATTERY DRAIN, SEARCH "WAKE LOCKS"... Better Battery Stats here on XDA is a good tool for figuring out the cause of wake locks.

IF YOU DON'T READ ANYTHING....PLEASE READ THIS!!

PLEASE be respectful and REMEMBER that this is FREE! I do NOT work for you! I have NOT and WILL NOT ask for donations for any of this! If you wish to donate, that's on you and that's just that.... a donation! YOU WILL NOT get an early copy of ANY ROM and I will not post your name/username anywhere....just not my style! Also please don't ask for ETA's or expect updates based on other things i.e. someone fixed this or whatever the case may be! :) I do this when I have the free time. I have a wife, kids, job, and life outside of xda that comes first. This is my hobby, how would you like it if someone was going around asking when you're gonna be done with that game or model car or whatever your hobby is. So let's all play nice, get along, and have a good time. I appreciate all constructive criticism and suggestions. Doesn't mean I will listen to you, but I will hear you out. I may sound snippy sometimes, I usually don't mean it to come out that way. You can't use tone except for all caps lol. Positive feedback and screenshots are encouraged so I know what you guys like. Thanks for following my requests. Enjoy!:D:):beer::thumbup::D:sly::cool:
