[Q] Battery Life Sucks

I dont know what it is, I have a task killer that kills running apps but it doesnt seem to work.
In 20 mins my battery drops 10% and i dont do much so i dont know what cases it.
Does anyone know a forum that I can get info from? OR any kernel that can help me with battery life?
If your going to be rude please dont comment because I WILL return the animosity!!! THANK YOU!

Task killers cause more problems then they solve, don't use them.

Well what can I use bc nothing seems to be working at this point.

What's your battery usage showing as the process that drains the most battery.
It's probably background sync from e-mail or IM clients.

Many are using the dopio kernel found in the dev section and setting the main to conservative, then creating one profile that sets the cpu at 245/245 when the screen is off. I have also seen/used a free app "juicedefender" that in theory looks helpful. Unfortunately, I suffer from obsessive ROM updating disorder and cant speak to how effective these methods are as my constant reflashing and rebooting destroy battery life.

Honestly, i didnt check.
I was told it may have been trhe rom , so i flashed a new one.
Now im going to monitor it and see if i have any changes.

Aha!
I suffer from the same problem!
I installed the app and im going to see if it helps.
Thanks!

Did you wipe battery stats and charge properly?
I use Advanced Task Killer Pro and have it kill apps on screen off.
Along with SetCPU to clock 245/245 on screen off.
A day, little use, I go down 8%. Regular use, about 20%.
My max is about 4 days. Using CM6 with dumfuq's 844 kernel.

What rom are using? My wifes phone is running cm6.0.0 and when I checked this morning was over 2 1/2 days uptime and 42% battery left.

[Q] SetCPU Superuser Permissions

So I'm on a visionary temp root, overclocked with setcpu. Ive set up several different profiles but I've noticed that my battery life with the profiles isnt as good as other users have claimed.
I have noticed that when i open setcpu sometimes a little message will flash up saying that setcpu has been given superuser permissions. Does this mean that prior to opening the program, it didnt have permissions? If it in fact did not have superuser permissions, could that be why my battery life is less than expected? (i.e. The program didnt have permissions and thus couldnt use the profiles to slow down cpu speed upon screen off, etc.) The message does not come up every time I open setcpu, but it seems to come up when I havent opened the app recently.
Any ideas?

From my understanding, you only set it once. i had set a widget because i thought set cpu had to be running. But i deleted it because if you think about it....superuser app already has the permissions set, and when you open setcpu it shows the current speed.....if it wasnt working it would show 800mhz then KICK into 1 ghz?....thats what i think. You shouldnt need to worry.

Great, thanks for the response.

same here. from time to time this popup comes.
anyway i cannot see any benefit from running setcpu as the profiles are not working for me.
i tried setting up screen off profile. this never triggers.
i leave setcpu deinstalled now. battery life is good so far

Good question. Can't find anything in logcat.

set notifications.
on the magic you could see him switching profiles right after turning on the screen
you wont see it on the g2

I agree, something is fishy with this. EVERY time I open setcpu it gives me the su permissions granted window like its not being saved in memory

EDIT: After shopping around on the market I came across an app called "CPU Tuner". The UI is nice and has roughly the same customization as setcpu if not more. It does take a bit of getting used too but i'm more than willing since the profile notification actually cycles with this app vs. setcpu. I'll give it a shakedown tomorrow as it's getting too late here to test.

cpu tuner doesn't work for me.
in profiles, it just shows 700mhz to 800mhz, which makes it useless as i want to underclock to 200 when screen is off.

That toast pop-up is nothing to worry about, its just something that has featured in the last couple of SU builds, it doesn't mean your app is not working.
I just turn the notification off in the SU settings.

I can now confirm that the screen off profile is not working correctly. Before going to sleep last night, my phone had a charge of 99%. I did not have anything running (no wifi, bluetooth, sync, etc.) and I woke up to 81% battery. It never killed that much overnight before overclocking. We gotta get this fixed.

i have mine set to 1ghz max 245 min profile screen off 245/245 priority--100..and put a widget on my main screen. My phone has been on screen off for the pat 5 hours....and drained only 2% battery life.....i dont understand why it doesnt work with some peoples phones??!!. is it different cause im using a desire z and yours a g2?...i HARDLY doubt that would be a problem :S..
have you tried the widget?.when going to running services, my setcpu app has been running for ever. aka profiles and setcpu working.

Running the setcpu widget on my phone caused instability issues at higher clocks (feeling ballzy w/ flippy's 1.8 kernel). After removing the widget my profiles were hit and miss for some reason.
As far as the battery issue goes, anyone running CM RC2 and earlier might want to check out nightly 36, apparently there was a memory leak causing battery drainage ( I don't know anything about what it means but common sense leads me to believe a leak is bad lol). If anyone is still not satisfied with setcpu I highly recommend CPU tuner.

Yes I have the widget on my homescreen. Weird that so many people get different results

Could the scaling be giving people varying results? I don't even really know what they do, I have mine set on ondemand. Would someone mind sharing what exactly the different scalings do?

http://www.droidforums.net/forum/rescue-squad-guides/47871-overclocking-101-a.html
Centered around the OG Droid but basic concepts still stand.
- Just picked up an app called SuperPower, had it a while back and had issues..but it's been update a lot since then. Looks like it's an all purpose battery management app that has the ability to govern cpu speed also. I'll test drive it and see how it works.

My battery life has improved markedly since installing CM nightly #36 and Pershoot's latest kernel. I've been using my phone pretty heavily over the last 8hours and still have over 50% left. Lots of texts, emails and websurfing etc.

Wimax light keeps coming on with cyanogen 6.1.2.. why?

I flashed cm 6.1.2 and the wimax light flashes periodically, why? And why does the battery light turn green when the battery is Only charged to 90%?
Sent From Tapatalk.

Don't know about the battery.
But the wimax light is used for notifications in CM

The wimax light is used as your notification light in place of the normal notification light. This is beneficial because you can see if you have a message if your phone is charging.
The light turns green at 90% because the battery is basically charged at this point. HTC's own charging cycle will go to 100% then back to 90% and back to 100% etc. so they obviously think 90% is fully charged as well.

Oh.. i see.. i see. Thanks for your input guys! I appreciate it. Also, can i use set cpu with cm 6.1.2? Because whenever i overclock to 1031mhz or something higher, it keeps restarting.
Sent From Tapatalk.

You can use setcpu, but it appears that frequency is a little too high for your phone.

I wonder why it was restarting before. Its not doing it anymore.

What kernel are you using? The stock kernel does not support overclocking, and is probably causing your problem. I use the snap kernel with CFS, and have my phone overclocked with setcpu to 1190 mhz on CM6.1.2

The stock kernel supports overclocking just fine. Some phones are just a little picky on overclocking. When I first discovered phone overclocking I was up on 1113MHz performance while screen on, 245MHz powersave while screen off. I got pretty good battery life actually, but I change to 998MHz Conservative while screen on and it's so much better battery and I don't notice any difference.
I'll crank it up to benchmark kernels, but there really isn't much of a need for it (maybe for playing games) and it can cause these random reboots that get irritating.

Im using the default kernel that came with 6.1.2.
Also, how do you check system sleep and uptime on cm 612?
Anyone trying collin ph? If so, what kernel do you have?
And to contribute. I think its an issue with the rom because i was running 1190mhz on myn just fine.

Been absent from the G2 scene, need suggestions.

Ive been using CyanogenMod for a while now and for the most part satisfied. Im running 7.0.3 and occasionally experience a few hiccups or oddities. For example, at work I will enable wifi. If I am out of range of the wifi for a while with it still enabled my phone will overheat and shut off. Sometimes wifi calling won't work. I had to restart my phone a few days ago because data wasn't working, but the icon appeared on the notification bar. I'd like to know what other ROMs I should try that may fix these annoyances. Also would it be worth checking out radios? Battery life is decent, but if theres a ROM i should try to get more battery life please recommend it. I can get 8-10 hours, about 1 hour total of tethering and wifi enabled for 5. I'm only overclocked to 1.2Ghz.

The 7.0.3 official is over a month old. Since then many improvements were made and bugs fixed, so I recommend the latest nightlies.
Regarding battery life, your max is 1.2 GHz but what is your min speed? Also, are you using an app like SetCPU or CM's built-in setting? What governor are you using?
Also, it probably makes more sense to post your questions in the official thread.

min is 800mhz, governor is on demand. I wasn't aware they were still doing nightlies.

Is it SetCPU thats draining my battery? I'll try going tomorrow with it uninstalled. Any suggestions about my data? Sometimes I'll have to restart my phone after having wifi on for 5 hours to get my data to work. Sometimes my wifi calling doesn't work until I restart. Would flashing a radio mod work?

That's an unnecessarily high min, for sure that's one factor for why your battery life isn't so good. Current draw scales roughly linear with CPU speed, as seen in this study. I get by just fine having a 245 MHz min.
Also, SetCPU conflicts with CM's built-in settings if you have both "set on boot". Like master.peterm, I also prefer CM's built-in CPU controls over SetCPU.

Why would you want 800MHz min? AFAIK that's the non-OCd max on the G2.
Unless you keep CPU hungry applications running all the time this is going to eat your battery away.

[Q] SetCpu VS Voltage Control Lite

Im currently running SRF 1.2, twilight kernel. Im interested in trying voltage control but dont completely understand the app as i do setcpu with its profiles and all. I am more into saving battery life while sleep than overclocking. My phone is fast enough. For undervolting, what do you guys suggest? Thanks in advance

There's nothing you can do with voltage control you can't with set cpu. I think vc pro does allow you to over volt but if your hitting your desired freq's without freezing you should have no need.
Cd's or tapes?

You say you want to save more battery while sleep...then you need to check CPUspy and Spare Parts to make sure your phone is going into deep sleep. No change in voltage (which VC allows you to do) will save or use more battery there. What you want to look for is partial wakes...programs that disturb your phones sleep by syncing or running while sleeping. Change the syncs to manual or uninstall apps using too much battery in standby.
As for any undervolting or overvolting, every phone is different..some can tolerate no changes in voltage where others will take anything you give it. Small changes should be tested thoroughly before applying upon boot so if your phone freezes during a test it will revert to a working voltage upon reboot.
