I've never cared about battery life before because I'm typically near a charger however I'm going to the beach for a few days and will need my phone to last.
What's the best kernel/set up for me if I'm running Fresh 3.1.0.2? I don't care about performance, fps, mflops, etc for these few days as long as the battery lasts and the phone is stable. I have setcpu on my phone but don't really know how to use it.

The latest cfs kernels are supposed to focus more on battery life than performance. Do you underclock cuz that's a big help too.

At 998 max now, where should I be? Which cfs one?

I'm running Fresh and Netarchy's 4.1.8 kernel.Creating a set CPU profile for when the phones screen is off will increase your battery life quite a bit.My screen off profile has the CPU max at 245 ghz and the min at 128.You can also scale back your max from 998 mhz to around 500 mhz and save battery without your phone being so slow that its really noticeable during normal use.

Interesting. What kind of battery life do you get? I thought I read a while back that going below 245 was a bad idea. Guess not?

It's more stable with the newest kernels. I'm set at 245 min and max when the screen is off and I usually see a 1% loss every couple hours but I haven't paid a lot of attention to it lately cuz like you, I'm usually near a charger. Battery life while using the phone still isn't great but I kind of expect that from a phone like this. There are some good battery conditioning tutorials in the forum that help quite a bit too.

i like the screen off profile, as that makes a real difference for me in battery life, however i see no point in having battery profiles. do you really want your phone to become slower just because you drop under 50% batt?
normally i would want it to keep going full speed and in the case that im on the road and need to save battery as much as possible i would change the setcpu profile myself (and probably switch off sync and 3g)
Your <30% profile will never kick in, since that is also <50% which has a higher priority.
Newb question: Does one have to have a rooted phone to install Set CPU?
^^^ Yes.
SetCPU needs superuser privileges to do its thing.
Priorities fixed now, I used it with less than 50% and the phone was just as fast doing regular tasks and web browsing
Am just using screen off dont need to use any other settings.

You also need a custom kernel, the htc one can only underclock not overclock

I just use <30% battery, 768Mhz. I let HAVS do all the rest.
So because I have a custom Rom Leedroid, I dont need to disable the driver?

What is HAVS?
Also, what's better for batt conservation (w/out sacrificing speed): Undervolting or underclocking?

HAVS is a set of instructions from the kernel governing the CPU, it undervolts and under clocks the CPU when it is not in use. Undervolting and underclocking go hand in hand.
I have just 1 profile:
screen off: max around 384 MHz. and mim 245 MHz.
Does that makes sense? :-O
Hi
Baterry usage
29/30ma in standby, isn't that too much? When IDLE
HD2- normaln/ idle 3-8mA
Normal for G2 is ??
Thanx
Virtuous v1.0.1 (HTC Sense 1.85.72.2)
1.85
T-mobile g2
usage only 2g (EDGE)
yeah thats fairly normal matey, mine is always on 30ma in idle and 250-300 in use.
my battery lasts a full day sooo i dont mind
my old hd2 lasted me a whole day as well.
i dont mind much difference in battery life between the two phones
just make sure you use setcpu and make a profile so that when the screen is off the cpu min is 256 and the cpu max is 256... you could set the max a little higher if you want but i have no problems using this setup.
Currently on miui and I have 3-8 on idle on average. I always check my ma usage with current widget.

quick question what is miui like?
im guessing from the looks of it its like android with a smoother interface like ios
What kind of idle consumption are other people getting?
I feel like mine is kind of high, but not sure. G2 stock OTA rom. Perm rooted and Oced, running SetCPU. Currentwidget says somewhere between 37-40mA in idle. That gets me something like 30-33 hours of pure idle on wifi calling.

My DZ (currently running stock rooted Sense 1.82) idles at about 28mA if I have Wi-fi/data off, 2G only, and SetCPU locking the CPU to minimum when the screen's off... about 32-35mA with Wi-fi/data on and 3G (SetCPU still locking the CPU to minimum when the screen's off)

Well today I flashed the Kernel and I think I have another issue which is causing Major battery drain.
On the Charger at 1:30
And again at 4:30
I bump-charged this morning too.
Here's what Android System had been running
And finally
What's up with my battery usage? I even have a 1500mAh Evo that doesn't seem to help.
Maybe it's my rom?

I was having a similiar issue as you ,running Business sense Z rom I installed Lou's number 8, I wiped Dalvik and cache and battery stats now the battery doesn't drain as fast. Previous to doing this I was only getting about 8 hrs on a full charge. Also my dislpay was around 70% is down to around 40%
34 minutes later peep the battery level

What is your brightness set to? I'm lead to believe high brightness is the number one cause for poor battery life. In general, your screen is the number one draw from your battery. By the one screenshot of battery usage, I might be on to something
edit: turn off the gps too if you havent.
I wound up flashing a recovery of Incredibly re-ingineered.
Check out the data used:
I found a temporary fix.
Today I burned through 4 batteries
Totaling 5400 mAh (1-1500 evo & 3-1300 eris/incredible batteries).
So yeah, lame.

Maybe try out a AOSP rom, sense roms sync too much, too often. Then start tweaking usage + other stuff.
Consider downloading setcpu here on xda. Set main to run at 600 MHz max, min at 128. Set to conservative and hit set on boot. Make 2 more profiles, a temp and a screen off to have the same values: 384 max, 128 min. Temp should kick in at around 40C. Then go to advanced, change up to 75, down to 25 and freq step to 10. If you want to go a little more crazy, cap it all off with juice defender free.
If you do go AOSP, get chad's latest then flash the aggressive HAVS settings. If you do do this, you might want to then go into setcpu -> info and run a stress test just to see if it is stable.
Thank you Sir/all, I'll look into that.
This is good info for myself & others.

Try a different kernel. I tried Ziggy's and battery charge pretty much evaporated. Switched to Lou's #9 and it's been smooth sailing ever since.
Hello all... I'm new to Setcpu and have been able figure out how to OC and UV while still keeping everything relatively stable. As of now I'm experimenting with making profiles, I was wondering if someone could post a screen shoot of their profiles and pass on any advice. I am running TNZ Blend 2.6.2 with the Hitman kernel. Here's a screen shot of what I have so far.

The only thing I would comment on is your "screen off" there is no reason for it to be scaling/jumping from 800-1200 "ondemand" while the phone is not being used or the screen is off in general, just have 800 low and high or have 800 as your high and set it to "performance" so that there is no polling being done and it will set itself to the high value which would still be 800 anyway.
You might have a reason for that setting, just trying to save you a little bit more of battery juice.
Definitely bring down that screen off! I have mine set to 200-500 ondemand. I'm sure it'll save you a lot of battery. Also the battery 100% is kinda pointless because that's what the main profile is for. And expect your phone to get extremely hot if you use it while charging since you have it overclocked. I did that same mistake now I keep it at 200-800 to avoid the over heating.

Just a recommendation...you should give tegrak a go. I find it to be much more beneficial than setcpu...
Why scale cpu depending on the battery level? I prefer scaling CPU on my phone by the temperature. 1.6Ghz normal usage and then gradually scale it down if it gets too hot. I bought this phone for its performance, not battery life, which actually is pretty amazing for such powerful device.

be careful with Tegrak, as it doesn't work with some of the non stock kernels, and will freeze your phone for sure..
Pretty good. You don't need the battery>100% profile. Adjust that from the main page.

I've been suffering massive battery drain on my phone since trying out a different region stock(xxml8) and flashing CM9 over it. Even after a complete wipe and restoring my old stock XXKL3, the drain is the same. I get 10hrs at best. Cpuspy tells me my 122Mhz state is unused, so after deep sleep the next state is 245mhz. I never used cpuspy before my battery problems so I don't know if this is normal on stock rom. Or could playing with the governors on CM9 break something with my cpu and causing huge drain? I think if the 122Mhz was available to be used I would use less battery. Any ideas guys?

-On the frequency i've been always using 122mhz--1401mhz because it saves power on lock screen and makes my battery last longer.
-you are not supposed to use 122mhz because you cannot listen to music at 122mhz because it stutters and laggs. thats why default is 245mhz.
-If samsung made the slowest speed 122mhz everybody will be complaining on music.245mhz can play music with no lagg and stuttering.
..............on demand 122mhz to 1401mhz is the best for me.................
Using Antutu Cpu Master I've been able to set the minimum frequency to 122Mhz. Will check if helps. However, my battery consumption with screen on is still huge. Don't know how I can fix this. I could get close to 6hrs continuous screen-on time before.

WOW my phone is amazing is nearly get 8hours(7h 53m) of continually using my phone through-out the day.
When im power saving it get 11hours with still 41percent left.
I've noticed recently that my battery is bloated. This can only mean it's physically degraded that's why I've lost so much battery life. This only happened after I flashed CM9. Before then I had a day of battery easily. There was a lot of overheating with CM9 maybe that was the reason.
Sent from my Wonder
yeah after I flashed a ROM my battery life was bad and my phone Battery got dangerously hot 50+.
so now I am on stock because my phone runs very cool and has much longer Battery life.
