Battery Settings for Darkstone Froyo 2.1

Hey guys, I posted these settings in the main thread of darkstone, and it worked good for some, i'm making this thread to show the setting i'm using to conserve bettery.
I have been using Setcpu and advanced task killer combined and so far my battery life is amazing. I had the phone unplugged and fully charged at around 7 pm, used it for few calls and some gaming and also downloaded some apps, it was at 70% when i went to sleep at 4am, now it is 10 am and the battery is 66%.
You need SetCpu, you can get it from here http://forum.xda-developers.com/showthread.php?t=505419
And Advanced Task Killer found on market for free.
I thought I would share those settings hopefully they work for you guys too,
For SetCpu:
Main Tab: max 1113, min 245, ondemand, check set on boot
Profiles: 1- Screen Off, max 245, min 245, ondemand, Priority 100
2- Battery <25%, max 652, min 245, ondemand, Priority 0
Advanced: Sampling rate= 20000
Up Threshold= 35
leave the rest at 0's and check set on boot and apply.
For Advanced Task Killer:
Go to setting, then auto kill level chose "aggressive", and auto kill frequency set it to "when screen turns off"
I'm using radio 2.12.50.02_2 and stock Tmobile US ROM HSPL3
I hope that helps some of you.

I've had major issues with battery drain. The best I've got so far is about 5% to 7% drain per hour on standby.
I'll try your recommendations too.
Battery is the only thing holding be back from using Android as a full time OS.
Do you charge your battery in Android or in Winmo?

got settings from other thread, thought they were working well turned out they were not lol had to jump back builds

Battery life is keeping these from being fully usable. I can't make it through a full day, I have tried juice defender, set CPU (max fre 800, 245 w/ screen off), turning sync off. I always get at least 5% drain/hr at idle and obviously worse than that when I use the phone.
I am going to charge overnight tonight in win mo then boot android tomorrow morning and see if I can get through the day tomorrow.

I charge using android, and I have to agree the only thing we need now is a better battery life, thats why i've been trying all different kind of settings and this worked best.

lol yeah its strange that those settings work for some people and not for others, I guess it depends on the radio/ROM they have.

Ok let me know if these settings work for you.

I have the same config in this build
[BUILD][17.08.2010][mattc Leo + Froyo w/Sense 1.5b][Kernel: huanyu 2.6.32.9 #6]
and it is working well even there!
I hade 11 hours down to 15% left of battery yesterday.. and I hade it on surfing by wifi and trying some new games and hade a lot video streaming through youtube the last 2-3 hours.
Before I couldnt last for more than 3-4 hours and the phone got very varm....so this i a start and a very usefull app to use!
If you want to extend it further turn of "data connection" at the point you know your not gonna use the phone for a while.

@Notorious.Marwan, won't having setcpu at 1113 for both max and min be draining the battery more as opposed to having it at 1113 for max and 245 for min? or would the difference be not noticeable at all?

Notorious.Marwan, those settings will not be very good for battery life.
You have max and min set to full clock speed...this is going to use a lot of battery power.
My settings will give much better battery usage...I get 2 days from my HD2:

Your problems with battery life are due to SD card usage. Plain and simple. Try a class 2 card for Max performance battery wise!!!

I am going to try this.....I was on Darkstones HD2Froyo without setcpu and batterly lasted only 6hrs maybe even less.......
Now i am using Mattc-NexusLeo_v1 build w/ the lastest kernel, used the default or suggested setcpu settings from one of the xda members and i am never at full 100% only 99% or 98% and gives me about 8-12 hours of batt life.
I will try your settings and report back in 24hrs with an update, thanks again for the info!

Also too...Something that I missed at first...In the Advanced Task Killer settings...you have to ignore SetCPU or it will kill it when you turn the screen off and defeat the whole purpose.

Still ridiculous battery drain. 99%->93% in 27 minutes. Using mattc 1.5b.
I've tried the following:
-SetCPU
-juicedefender (data on only when screen unlocked)
-calibrate battery
-delete batterystats
Still need to try a class 2 card versus the class 4 the phone came with.

do a task killer, I think you have tons of contacts, so you always keep network running.

UPDATE:
I set my CPU main to "ondemand" at 94% within 30 mins I was at 74%. So I charged for about an hour back to 99% setcpu main screen back to "conservative"..
Today 8/21
- 5am - 99%
- 7am - 90%
- 730am - back on charger
-10am - FULL%
-11am - 95%
-2pm - 85%
- 3pm to 8pm, this is when i got locked up and sent to jail for 5 hours, soooo now I am at 59%
Sooo, in conclusion for mattc NexusLeo Builds vs Darkstone, keep everything the same except your main screen
Max 1113600
Min 245000
Scaling conservative
set on boot
thank you good night

I have found the best combination is Advanced Task Killer and Juice Defender. Don't even need Setcpu with the combination of the 2 above, meaning your build runs as fast as it can, even overclocked I can get easily 1 day out of it. Overnight drain is ~15-20%.

Is it worth it - in terms of speed, fluidity and no screen lag - to set the max value as 1113, instead of the default (998)?
I'm always thinking that we're burning the CPU and draining much more battery.

O/C Voltage Survey

Alright guys, I've had my Dinc for almost a week now, and I think I've found a pretty good set up as far as what I need goes.
I am a professional auto detailer so I have my headphones in about 8-10 hours a day. I LOVE pandora and normally if you play pandora it will kill your phone within 4 hours.
SOOOOOOOO I decided to create a little survey to see what Kernel/Rom, O/C app, Governor, Profiles/Settings, Notes, etc.
Please guys share your settings, I would love to try out everyones setups and see what really is the ULTIMATE set up for the Droid incredible
Please everyone stick to the format just so its easily understandable for everyone who isn't part of the forums or doesn't understand what everything is.
I'll start with mine
Rom - Stock Plus
Kernel - GingerTiny
O/C app - SetCPU
Governor - On Demand
Profiles/Settings - (1) Screen Off - Priority 100 - On Demand - 245 max - 128 min
(2) Battery <101% - Priority 50 - On Demand - 960 max - 128 min
Notes - I've found I can last about 10 hours streaming radio the whole time
Also, I've found that IheartRadio uses less resources than Pandora, Thus using less battery.
When I'm not streaming any music either, I have had my phone stay on the SAME percent - 66% - for 10 hours STRAIGHT and then It stayed on 65% all night when I get home, and when I woke up in the morning it was only on 60%

Rom - Touch Of Blue
Kernel - Latest GingerTiny
O/C app - No-Frills CPU Control
Governor - SmartassV2 (245 min / 998 max)
I/O Scheduler - SIO (Set with No-Frills)
Voltage Control - IncrediControl (-25v all freqs min and max)
Profiles/Settings - None, they are not recomended or needed as the kernel has a built in sleep mode.
Changing from Ondemand to almost any other governor and slightly undervolting, will greatly increase your battery life.

And not using a sense rom will add 2 to 4 hours depending on use in my experience

I'm gonna try this out today and see how it well it works with streaming music all day. The reason I've set profiles is because I feel like when I'm playing Pandora andthe screen is off, it will force it to go to the lowest voltage I have set, whereas if I don't set profiles it will play at whatever voltage feels nessecary. That's just the way I see it, if anyone can confirm or deny this let me know.
BTW nice addition to the survey, Idk why I didn't add io scheduled in the first place lol
Sent from my ADR6300 using xda premium

thanks for information..this is quite interesting...i gotta try this out

The phone doesn't sleep when music is playing so then what speed is running can influence battery. If you're curious try it without any profiles and you can still use ondemand.

I do use an app called Automateit PRO which I have used to create many different custom "rules". Every rule has a "trigger" and an "action". Some of my rules are used to automatically disable (or enable) 3G, Wifi, and GPS at certain times and/or situations that are appropriate. That really helps with battery usage...and its convenient that I don't need to do the enabling and disabling manually. But streaming music would require pretty much constant data connection of one kind or another.

My custom rom setup
I'm running CyanogenMod 7.1 on my Dinc.And Go Launcher Ex With Ice Cream Sandwich 3D Van Theme overclocked with Cyan to 245min. 1036 max. So smooth an fast.

[Q] Am I losing smoothness?

Hello guys, so I am running ParanoidAndroid 3.99 RC2 (updated yesterday) and Faux's kernel on the Nexus 4, but I feel like something's wrong.
So the device is VERY known for his smoothness and power, but I don't feel like it's giving me what I want - compromise between battery and smoothness. Might be a placebo effect but still..

Where could I cut/gain with this settings?
On a side note, can a display color profile (in this case Faux123_Good) drain more battery than another?
Also, I use Chrome much. I heard that Chrome drains more and has worse performance than stock AOSP browser. Is that true?
About the wakelocks, I just notice high values of msm_hsic_host, sns_async_ev_wakelock, and "wlan". I know msm_hsic_host wakelock is perfectly regular (and yes I know we are using a tablet SoC plugged into the modem with a USB port), dunno about the other ones.
Thanks in advance

Li'l up. Dunno where to look.

I can only suggest trying a different ROM/kernel combination.

I've actually figured out what the problem is. No wakelock issue at all. It was the intellidemand governor; switched to interactive governor and things got yah, smoother. Intellidemand is based on ondemand and that means smoothness is not as good as interactive; sure, I can squeeze more juice out of the battery with intellidemand but I choose smoothness over couple more hours of activity.

How to tune cpu governors to extend battery life?

Hi guys, what's the best setting to save battery? I tried to turn off the a72 cores using in the hotplug section in Kernel auditor, and switch the a53's governor from interactive to powersafe, but the phone gets to laggy...
For example when I'm on the train to work listening to music (from internal memory, not spotify o google play music), 3g data on, writing some message on whatsapp or telegram (no games, web surfing or facebook), the battery drops 15-20% and the phone gets hot in about 30 minutes! I'm on the LOS 13 (13/3 official build) now, with theEUI 19s and 20s the result was pretty close. Always auto luminosity set to 40%, and greenify hibernating unused apps like messenger, facebook, instagram etc etc
How Can I set the hotplug to switch off immediatily the a 72 cores when unusd?
Can I use custom governors like fairpark, glassfish etc ect?
Thanks in advance to everyone

Is your phone rooted?If yes then install kernel auditor and tell me what are the CPU and I/O governor that are available to you.

Try this in kernel auditor..
In hotplug Turn minimum CPUs big to 0
In Cpu change the minimum CPU frequency to 400 in both little.BIG

Yes it does not apply automatically.. Just use apply on boot this works most of the time..

yes you need to set "apply on boot"

Undervolting

What voltages can I set for frequencies from 2457 MHz? For now I have such voltage settings.

You must've spent a lot of time perfecting that. Can you remind me of your SoC's PSV value? Boeffla's app lists it in the Overview section as ASV/PSV.
I tried your 600 mV idle voltage on my PSV 9 phone. Didn't work, got a soft reboot. 625 mV seems to work. Seems crazy this is possible when the stock idle voltage is around 775 mV.
https://forum.xda-developers.com/htc-one-m8/general/guide-snapdragon-801-clocking-voltage-t2807173
edit: Tested for a few hours. Currently using
990 mV - 2534 MHz
1010 mV -2611 MHz
1030 mV - 2764 MHz
1045 mV - 2841 MHz
1075 mV - 2899 MHz
Seems stable in stability tests, haven't tried in daily use yet. If you want to increase the max speed the sweet spot is probably 2764 or 2841.
If you haven't seen this chart yet it has estimated voltages for each PVS binning on speeds above stock, maybe it's what you're looking for. According to the table the "worst" voltage a terrible PVS stock phone will use is 1120 mV. If you do not exceed that while overclocking your phone will probably be okay.
Thanks for the voltage references, I'll use them to tweak some more!
I came up with a stability test that hopefully tests phone stability without causing it to burn up. You just need the Boeffla app and Termux.
-Make a separate Boeffla profile
-Manually select and apply the new profile every time you're testing the undervolt
-Add some extra startup delay in the Boeffla settings
-In the Boeffla app change the Tuned governor's profile to "Performance". The normal profiles don't really care about using high CPU states so you need this.
-Don't change the hotplugger, default is "Tuned"
-Reduce your max charging speed for AC and USB to 1200 mA if you want to do testing with a charger plugged in
-Try to start on 100% charge so less heat is generated charging
-Lock the GPU to 27 MHz. Why not? The screen will be off anyways.
-Make undervolting adjustments to your CPU states' voltages. Only tweak the values of one or two states at a time.
-Adjust the minimum and maximum CPU speeds with the sliders so your phone is more likely to hit the states you just tweaked. If you just tweaked a low CPU state set it to the minimum speed, and if you just tweaked a high CPU state set it to the maximum speed etc.
-Launch Termux and then "Acquire Wakelock" in the menu or in the notification bar
-Run this one-liner:
while true; do openssl speed -evp aes-256-gcm; sleep 15s; done
Click to expand...
Click to collapse
Explanation: No real reason to do it this way. Openssl's speed benchmark with AES is a cheap way to test CPU stability on many computer systems. This runs a benchmark on 1 thread, sleeps for 15s to let the phone cool off for a bit, and repeats. If the phone isn't throttling it will typically max out the CPU clock of the core the thread's running on. Sometimes you can spot anomalies when the benchmark scores deviate a lot. You can also add -multi [# of cores you want to test on] to run the test on more cores but this may heat up the phone too much and cause anomalies.
-Give your phone some cooling with a fan or something or put it on top of something that dissipates heat.
-Turn the screen off to keep heat down or keep it on low brightness.
-Check the phone once in a while to see if it's still stable
-If you are happy continue adjusting other values
-This test isn't perfect because it's not representative of real-world use but hopefully it's close enough :silly:
-The battery generally doesn't like it when it goes above 40C just pointing this out :silly:
-Possible alternative stress test: dim the screen to minimum brightness and play a video the phone doesn't really like such as webms
-If your phone is looping from bad settings just hold power + vol down + home to force a hard reboot

edit: Tested for a few hours. Currently using
990 mV - 2534 MHz
1010 mV -2611 MHz
1030 mV - 2764 MHz
1045 mV - 2841 MHz
1075 mV - 2899 MHz
Seems stable in stability tests, haven't tried in daily use yet. If you want to increase the max speed the sweet spot is probably 2764 or 2841.
If you haven't seen this chart yet it has estimated voltages for each PVS binning on speeds above stock, maybe it's what you're looking for. According to the table the "worst" voltage a terrible PVS stock phone will use is 1120 mV. If you do not exceed that while overclocking your phone will probably be okay.
Thanks for the voltage references, I'll use them to tweak some more!
I came up with a stability test that hopefully tests phone stability without causing it to burn up. You just need the Boeffla app and Termux.
-Make a separate Boeffla profile
-Manually select and apply the new profile every time you're testing the undervolt
-Add some extra startup delay in the Boeffla settings
-In the Boeffla app change the Tuned governor's profile to "Performance". The normal profiles don't really care about using high CPU states so you need this.
-Don't change the hotplugger, default is "Tuned"
-Reduce your max charging speed for AC and USB to 1200 mA if you want to do testing with a charger plugged in
-Try to start on 100% charge so less heat is generated charging
-Lock the GPU to 27 MHz. Why not? The screen will be off anyways.
-Make undervolting adjustments to your CPU states' voltages. Only tweak the values of one or two states at a time.
-Adjust the minimum and maximum CPU speeds with the sliders so your phone is more likely to hit the states you just tweaked. If you just tweaked a low CPU state set it to the minimum speed, and if you just tweaked a high CPU state set it to the maximum speed etc.
-Launch Termux and then "Acquire Wakelock" in the menu or in the notification bar
-Run this one-liner:
Explanation: No real reason to do it this way. Openssl's speed benchmark with AES is a cheap way to test CPU stability on many computer systems. This runs a benchmark on 1 thread, sleeps for 15s to let the phone cool off for a bit, and repeats. If the phone isn't throttling it will typically max out the CPU clock of the core the thread's running on. Sometimes you can spot anomalies when the benchmark scores deviate a lot. You can also add -multi [# of cores you want to test on] to run the test on more cores but this may heat up the phone too much and cause anomalies.
-Give your phone some cooling with a fan or something or put it on top of something that dissipates heat.
-Turn the screen off to keep heat down or keep it on low brightness.
-Check the phone once in a while to see if it's still stable
-If you are happy continue adjusting other values
-This test isn't perfect because it's not representative of real-world use but hopefully it's close enough :silly:
-The battery generally doesn't like it when it goes above 40C just pointing this out :silly:
-Possible alternative stress test: dim the screen to minimum brightness and play a video the phone doesn't really like such as webms
-If your phone is looping from bad settings just hold power + vol down + home to force a hard reboot
