X8 Battery Life

[steconnor]

Hi All,

Stephen here, new to XDA. Not sure if this is the right place to post.

I'm looking for advice to help extend my Xperia X8 battery life. I have a rooted Xperia X8 running stock rom and kernal (android 2.1), manufacture details 10W42.

I use my xperia X8 solely as a bike computer because it has in-built ant+ receiver but its use is limited up to approx 2hrs due to battery life . My main question is are there any custom Rom's available which do not effect the ant+ protocol that is installed at manufacture and that extend the battery life substantially. I would require 3-4hrs on constant screen on with a bike gps app (IpBike) running so that I can use the xperia X8 as a bike computer.

I'm a software developer so flashing roms and kernals shouldn't be an issue. I would guess that a later version of android would probably help!

thanks

I can you recommend a good roms that I've tried (do not know about the battery life, I think it's good for both roms)
1. GingerDX v031b ( android v 2.3.7 ) for stock kernel - http://xdaforums.com/showthread.php?t=1188486
2. ROM 5.1.1 Super Lite for Xperia X8/W8 ( android v 2.3.7 ) for stock kernel - https://drive.google.com/file/d/0BzGb2aHCz2w6TjZoT0ItMFBvNjQ/view

Requirements:
Rooted
ClockworkMod Recovery (v014+)
Baseband 015

!!!very important!! use only those roms for stock kernel

currently I'm using this " 2. ROM 5.1.1 Super Lite for Xperia X8/W8 " and am quite happy - https://www.youtube.com/watch?v=MG27T_ZRqzk
