Optimux2X battery life with ICS

---

In threads in the Optimus2X development forum I often see posts that praise the battery life using new ROMs or basebands or RILs. The numbers always surprise me and make me jealous. I have read about some guy whose phone loses about 3% battery during the night, or some other guy who still had 75% battery left after 7h of 'normal' usage.

Today, I unplugged my phone from the charger at ten in the morning and 3 hours later, I had 80% battery left, with the phone only resting in my pocket in standby. Now, about 8 hours unplugged from the charger and less than normal use (15 min browsing, one GPS localization, two SMS sent) I am 25% battery.

I have disabled WiFi, decreased display brightness to the lowest value, always disable GPS & bluetooth unless I need it (which is very rare).
I am currently on owain's CM9 build 62, baseband 313 and RIL 218. I have also tried BB 725/RIL 725 (which caused big problems) and BB 420 / RIL 1120. Both did not give me a noticeable longer battery life.

Whats up with my phone or battery? How can I extend my battery life to the numbers said in the beginning?

i would say something is definitely wrong with your phone, rom or kernel. i use my phone even to play, games like dead space and more, and my battery always lasts for 1 day at least, also oc'd to 1.4 ghz.

I had the same prob, But I solved it,
now my phone survives a full day with normal usage.
Receiving/sending mails tweets facebook post G+ browsing the web etc.

try to drain your battery until your phone shuts down by itself
then fully recharge it after that unplug it and start it up again,
I hope it helps it did so for me.
