I don't know, but I think everyone should periodically use app mgr to look at the programs installed and delete the ones you don't want. I find that programs get added I know I never would have installed.

And everyone should look at the overclocking wiki; the kernel it uses lets you reduce battery life -- and it works, whether you overclock or not.

hi i had the same problem after update bat going down fast.
what i did i charged the battery when the phone says its full i unpluged it and pluged it in one more time.
it started charging again for an hour after that i had no problems any more the batery is now going a lot longer.

geneven can u recommend which one. i had kernel-config but thought that might be culprit so back on stock now. loading ideal crashes my phone so i normally just go for lv then load limits 250 900. not sure if that would increase battery life.

if u can let me know which config to try ill happily give it a go.

for me.....battery life span is quite longer now, in the last PR1.1, my device's operating time when using it to the limits (yes! overclocked) was 8-10 hours. in PR1.2 with the same settings and apps (plus more), the battery lasts for minimum of 15 hours.

I've also heard both increased and decreased battery life.

I have experienced increase in power consumption, so I checked top readings. The main UI (X.org & hildon stuff) was taking a combined 15% or so all the time. I rebooted and it dropped to normal 2%.

I guess something makes the UI stay alive or it's buggy itself and enters some endless poll loop.

there are already 5 threads about battery drain after pr1.2.......

Thank you for this info. It really helped me to zero down on the issue.

I too had terrible battery performance when flashing from leakjed 1.2 to proper 1.2. I did a complete re-flash including emmc and now i get at least a full day. That is with email, conversations, twitter, facebook, ap news and weather widgets all running on desktops. My email re-fresh is 2hrs.

Before I installed firmware 1.2, in recent days my battery was dieing pretty fast for some reason. I noticed that when I keep the wifi turned on it keeps connecting to one of the connections and as those connections require key/password to enter it connects to the router but doesnt really connects to the net.

So as it has already connected to the wifi router, the gtalk and skype tries to login all the time. Thus battery runs out within few hours.

However, when I disable the wifi the battery runs longer like it used to do before.

But i dont know why the battery runs out quicker these days because even in the past I never used to disable wifi but in those days I didnt notice it trying to connect to one of the available connections then trying to logon skype/gtalk like non-stop

So when you aren't using wifi, keep it disable and see if the battery remains longer.

Also I installed 1.2 only last night so I dont know if the battery still runs out fast if I keep the wifi on all the time. Need to test that in coming days

use /sbin/powertop and report the results?
