i think the battery is better now. this is with 3g, autosync and background data enabled but i've hardly used the phone but after 27 hours it's 52%. after my next charge i'll disable 3g and autosync to see how that works. suits me anyways as i'm going incognito this weekend.

btw i found an app that disables apps from autostarting, not just killing them after they've started. it's called autostarts, that is autostarts with an s. it needs root but it worked to prevent maps from starting. i know most apps don't use any battery when idling but it's a matter of principle and the knowledge that it is there bothers me. it didn't stop "Music" though so it doesn't work flawlessly.

description from market: "It needs to be running a CUSTOM ROM (an example is the famous CyanogenMod) with kernel frequency scaling enabled". have you tried it and know that it works?

Oh, nope.
Mine arrives monday, I'll then decide whether to keep it or give it to my girlfriend.

Either way, if I keep it, I'll work on a ROM and decent kernel, that's a promise. However, I won't post it here. Check XDA.

Oooo, i hope you keep it and work on a ROM.

yeah me too, it's nice that there's finally a dedicated forum section at XDA. hopefully there will be some custom roms later this year

pihx can you write which apps you removed with titanium? yesterday i reflashed to 10A again as i had experienced a lot of weird behaviour that i thought to be because of 10B but when i had rooted in 10A and uninstalled some stock apps others claim to be safe to remove then the same behaviour started. i think i uninstalled about 10 different apps but i did it all at once so i can't be sure what's causing it. but it's not the rooting itself, cause now i have 10B again and just rooted and the phone's still working fine. so it must be the removal of something that's causing the problems. but now when i haven't removed anything i notice increased battery consumtion. 6 hours disconnect and only 80% battery already. it's definitely something that drains the battery so it would be nice to know what you removed to get the same results as you have. cause i managed to get 48 hours without charging before when i had a lot of stuff removed.

I might not remember every app i uninstalled but i will try to name them from this list http://www.android-h...rnt-werden.html

AppAdvisor.apk -> LG App Advisor
Bubbles.apk -> LG Livewallpaper
CarHome.apk -> Cardock-App, wohl häufig für kurze Akkulaufzeiten verantwortlich
Finance.apk -> Börsen App
FriendsPluswidget.apk -> Social App
GenieWidget.apk -> News und Wetter-Widget
Gmail.apk -> GMail-App
LGOnScreenPhone.apk -> LG OnScreenPhone Suite
LiveWallpapers.apk -> Livewallpaper
LiveWallpapersPicker.apk -> Livewallpaper-Picker
MagicSmokeWallpapers.apk -> Wallpaper
NewsWidget.apk -> LG-News-Widget
SNS.apk -> LG-Twitter-App, LG-Facebook-App, LG-MySpace-App
WeatherWidget.apk -> LG-Widget

I think these were the ones i uninstalled. I might have uninstalled more or less, i'm not sure.

I'm getting really awful battery life on my p970.

With all services and apps stopped or closed it uses 100% battery with wifi on and over a 3g network (data off) within 24 hours. I'm not even using the phone in these 24 hours, its just been left on the side after a full charge... 23 hours and 2 minutes later and its dead.

I can get almost 50 hours out of my desire s with light>moderate usage, it was the same with my optimus one and moto defy.

So why does the phone use soooo much battery when it should be sleeping? Something is definitely wrong here.

You really need some sort of system monitor app that can record over time to see what is wasting your battery beyond the usual 3G, Wifi, GPS. It might not be the same for everyone, but there might be an app that is running in the background using more CPU then it should.

As for my phone, when it is doing nothing and just sitting on my desk, there are alot of apps open in memory, but none of them are using any CPU or so little it barely counts. Using the battery stats is not enough, you need detailed monitor software to see what is going on.

My phone is currently at 64% after 38hours and 24minutes after light use.

Are you on a custom ROM/KERNEL? if yes, which ROM & KERNEL are you using?

Well, seems i have done something that give me much better battery then before. I will try to write down what i have done and what might have been causing worse battery.

First, my phone is rooted using Gingerbreak. Then i used Titanium Backup to uninstall all kinds of LG apps i don't use, like Weather, Finance, Carhome etc. I did this days after i got the phone so it's a while since then. So over time i did these things....

I installed all sorts of task killers and free system monitor apps to see what was causing bad battery. I had also installed juice defender and a program called CPU Tuner that adjusts CPU after battery life, so it uses less CPU as the battery get's lower. None of this was working and i was getting worse battery if anything. 10 hours of idle and the battery was down to 75%

So what i did 2 days ago, was buy an app called System Panel by NextApp which is a resource monitor tool that can record what is going on in the background without using much battery. Next i started uninstalling apps like CPU tuner, Juice defender and even Titanium Backup. Then i kept moitoring use and noticed that the Battery widget was always using the CPU a little bit and also Email, so i removed the Battery widget and closed the Email task. I then charged the phone fully and went out to do some business. When i got home like 5 hours later, to my surprise, the phone was at 96% battery. It has used almost no battery even though i had used the camera and taken 3 pictures, made a couple of phone calls and had 3G enable (data was disable though). So i looked at the records of the monitoring from SystemPanel and after i uninstalled TitanumBackup, removed Battery widget and killed Email, the CPU activity was much lower, and only thing using CPU was background system files.

So now, after 21 hours, my phone is at 80% battery after light use and it's only draining very slowly. I've made phone calls, used camera, used Wifi, used Market to update apps and download and install apps.

I highly recommend you remove battery widget and any other LG widgets or apps that you really don't need. It seems there is nothing wrong with the phone itself, it's a matter of not using bad apps or widgets that is draining the battery. I am very happy now with my battery use. And if you have 3$ to spare, i can highly recommend System Panel.

If you want to know anything, just ask.
