[Q] The perfect SetCpu settings for powersaving

I'm really struggling with battery life at the moment. Has anyone got settings I can use to save on battery life in SetCpu? Profiles etc

+1
I'd like to know too.

I would also like to know =[ my battery dies wayy too fast. I have the darkstone froyo build on my htc hd2 phone energy rom. Any programs or SETcpu settings that will help out?

If your on a rom with preflock disabled then you can underclock.
The only thing you need to change in setcpu really is to make a profile for screen off and set it to 245 (or whatever is the lowest I can't remember) both max and min (leave it on demand, or interactive if your rom has that).
This should give you about 10-15 hours longer battery life

so i wouldnt have to make any other profiles like battery? temperature? stuff like that? should i get rid of my green power and advanced task killer?

No you can keep them (well I don't know what green power is....)
The other profiles are mainly only needed if your OVERCLOCKING, however if your not touching the default max (main profile) then your not overclocking (1ghz).
To save power you UNDERCLOCK which setting a lowered screen off profile would do.
If your slowing the CPU down then the temperature will not rise, so that profile is not needed.
And you don't need to slow the phone down when your using it so none of the others are really needed either.

i think im kinda get what you're saying (sorry im kind of slow) so i had just deleted my other profiles and made a screen off one have it set to max all the way right and min all the way left, on demand, priority 100. Now on the main screen i think i touched it cause i read somewhere for max all the way to the right and min all the way to the left. This is confusing lol

The settings I have for my Desire:
Default:
Conservative 245-998
Profiles:
Screen Off - Priority 100 - Powersave
Charging/Full - Priority 50 - OnDemand 245-1305
Battery < 30 - Priority 0 - PowerSave
Running along side JuiceDefender, battery life is acceptable to me

That totally defeated the purpose of my question and others before me. Our battery lifes sucked without any programs so now we delete it?

I used darkstones froyo for awhile too. Battery drain killed it for me. I had no luck with anything. Changed to a nand build and its much better. Apparently SD builds just use more battery. With the SD froyo I could never stay below 60ma a few times would drop to less than 10ma but just not consistent. I lost about 8% an hour in sleep mode. Give a well designed nand build a go. In sleep I hover AT 4ma. My battery with Moderate use easily last the day, heavy use (multiple calls, emails, and browsing for an hour or two) still does require a recharge

Im using carbon ara theme with pcb just turn data off wen aint using it via toggle and have a profile for sleep in set cpu for min and max of 245 and from full charfe at 7am by 6 pm im still 65%. Thats using fb checkin email playing angrybirds and checking the forum

[Q] SetCPU

What are the settings you guys have to save battery life? Also How do I setup the profiles?

Help From No One???

I turn background data off, turn data and wifi off. My setcpu profiles. Screen off max300 min300,100 priority. I got a droid x and my battery lasts with medium to light use 24 hours before I have to charge.

Check your governor settings too.
I've found conservative with 80/55 up/down threshold, 10% steps to give a good medium between performance and battery life. Also, I've downclocked the max cpu speed to 921Mhz. 128Mhz for sleeping.
Edit: I do have background data turned on, as well as enable always on data toggled on under settings/networks/mobile data. Wifi is to never sleep. I do try to use wifi over 3g whenever possible - it extends battery life considerably.
With light use, I get 3-4 days, moderate use ~2 days, and heavy use will give a good solid day.

Can't thank from Tapatalk, but excellent reply. I like the detail.

N/P.. I experimented with a number of different settings a while back, and although i'm sure this could probably be tweaked even further, it works exceptionally well as is. One of the methods of measuring was to see the stats from 'time_in_state'. I was looking for good utilization of cpu freq's between the min/max. My other criteria was good response in interactive apps (email, browser, scrolling).
ymmv.
PS. I do not use setcpu, but the above along with the sleeping script in the rom (see below), achieves the same thing.

Battery life stats and questions

What's a good figure for battery life on the GS3? The best I've got is about 31 hours using on demand and bfq. Any one got better life using other settings? I heard someone getting about 43 hours life but that seemed to be a little unbelievable. Let me know what your getting
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

What you reported is definitely "the average". Most actually only get a day, if they're lucky of moderate use and have to plug in before sleep every evening and get going on charge in morning. So its more like 15 hours actually. And your 31 max is very common high end for people who've stretched it out.
I'm not sure if you're stock rom or not and if rooted either but that makes a big difference.
I'm rooted ( and would ALWAYS RECOMMEND ROOT FOR EVERYONE EVEN UF NOT FLASHING ANY ROMS AND STAYING ON STOCK. The ability to have full control is important.
Changing kernels and more importantly, undervolting, will give you that longer life you're looking for.
I'm currently on KyanROM with either Ktoonez or Faux kernel (heavily tweaking and testing both) and have this phone beautifully undervolted to exceptionally low and very stable mv numbers! Thus getting me that lovely 36-45hour average (you mentioned you saw posted elsewhere - yes it is possible and many are doing it). I basically only need to plug in every OTHER EVENING or night between 6pm and midnight depending on usage and I'm a moderate to heavy user (with a lovely 3-5 hours of screen time as well) AND I also have my phone overclocked to 1.8Ghz! Surprisingly, the oc doesn't make much battery life impact at all because the phone isn't constantly having to run at high levels, only in short spurts. Actually, due to rooting and kernel change I'm able to have my phone run as low as 192Mhz during much of its general activity and deep sleep ( which I get a ton of as my phone basically always goes into it when the screen goes off). This saves me A LOT of battery life.
I also use LTE, which is actually one of the biggest if not the largest battery hog, next to screen time of course. But with that being said I only use it when needed and have it turned off when not in use.
As for my peak I was able to squeeeeeze out 87 hours once, on my stock battery BUT that was with some abnormal(for me) measures that really help conservation. Ie, no LTE, under clocked to 1.2Ghz for good part of the three days, much less then normal screen time over the period of which I used it at lowest level with even further reduction via screen filter, I actually used airplane mode during my three overnight sleeps (which I seldom use but if you can hack it, do it! It can really save battery overnight. My current setup basically SIPS MY BATTERY AT 1% EVERY 3.5-4 HOURS OVERNIGHT WHEN IN AIRPLANE MODE), mobile data was off for most of time but did use my wifi at normal level (wifi uses less especially if good signal with few reconnects/scans), used my typical low UV numbers, kept my notification updates/syncs/wakelocks to a minimum and lastly kept my memory virtually clear if unnecessary background apps.
Doing ALL of this allowed me to get OVER THREE DAYS BATTERY LIFE. But keep in mind I seldom do many of these battery saving tips on a regular basis but some do and if you can, they WILL work to extend your life substantially!
To wrap up (this long winded post/reply) I'll give you my general UV mv range numbers and the typical everyday simple battery saving methods I use.
1.My voltage at lowest clock of 192mhz=800mv with gradual (smooth and almost linear curve) increase up to a mere 1200mv at a whopping 1.890Ghz clock.
I use NOOP scheduler with ONDEMAND governor most of the time, sometimes SmartassV2.
My screen off and deep sleep use this lowest 192 clock speed and with no wakeup lag.
2. I use my screen at 0% brightness most of the time (except when outside or in high lighting environment). I use the brighrness widget app to control this as it is easier and works better then stock settings. I actually even further reduce my brightness with Scree Filter App. That app is awesome and often use it solely for brightness control because it has full control and can dim it to basically full black if wanted. Which is MUXH lower then stock control. Fyi I use my phone a LOT more at night or in dark environment thus allowing me to dim screen HEAVILY yet it still is actually plenty bright with ample contrast in dark environments to do everything. This saves on my battery HUGE!
3. I use LTE when needed and GSM/HSPA+ when not. Seldom turn of mobile data altogether. I do turn off wifi when out and only using mobile data.
4. I use Screebl app to have screen turn off when not in use. Its great liitle app. Basically let's you turn down screen timeout to 15 seconds or less so screen is never unnecessarily on but it always stays on when in use due to the accelerometer and it knows when the screen is not flat on table! Its very annoying when browsing or doing stuff where screen isn't touched for long periods and the screen goes to sleep! But this stops that! So its always on when upright or in use and when phone down it turns off immediately.
5. Very important step and can take some time and research but making sure to keep partial wakelocks and apps keeping device awake to a bare minimum! DEEP SLEEP IS VERY IMPORTANT TO SAVE BATTERY! You basically want it to go into that every time your screen goes off and to stay in it uninterrupted for as long as possible. And many users phones are NOT making it into deep sleep due to partial wakelocks and they don't even know it or how to fix it. Not getting deep sleep can unnecessarily kill your battery!
I use a few tools here: Better Battery Stats/GSAM Battery Monitor/Battery Monitor Widget from within System Tuner Pro (which is my also my main and highly recommended tuner app for CPU oc/uc and UV,etc.).
These apps really help to determine what, if any, apps are causing partial wakelocks ( displaying in wake number amounts and overall wake time) allowing you to determine what to do to fix the problem and let the phone gets as much battery saving deep sleep as possible.
6.I'm not big on auto app killers and actually recommend against them as Android ICS does this already very effectively but do keep in mind that the more active background memory that is used, the more battery the battery is drained. So I personally kill unnecessary apps myself from the background whenever possible to save a little battery here and there. Using the apps listed above in #5 can really help to detect a nasty background app or service that is quite possibly unknowingly using a ton of CPU and/or memory, thus draining more battery and also often just slowing down your phone!
7. For those who can use it Airplane Mode is a big saver! Try overnights if wanted as long as missing notifications, emails, calls, updates, etc is alright for you. I seldom use it but it does help.
8. I almost never use my Bluetooth and GPS but when I do that is the ONLY time they are on. They get turned off immediately and really be careful with the GPS in particular because you might be surprised how many things on your phone will use it in the background, sucking your battery!
9. Be careful with sound and vibration levels. Haptic feedback too. I don't do much here but its anotherctip nonetheless.
10. Lastly is treating and charging your battery right! I found an amazing site linked down below in a couple of articles that really explains these batteries and how they work in a very in depth technical level this is still not too hard to follow. Aside from the two links I posted check out the others on the left menu as there is a ton of useful and educational info!

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
OK I've rambled on waaay too long here. Maybe I'll take this and post a battery savings tips thread with it lol. "10 points"!
Btw I've just received both my 3300mAh and 4400mAh capacity batteries. So I have much testing to do on those too and I plan on reporting back on them as well. Also with screenshots for data and proof...I can and will also post screenshots for all of the numbers and stats I've posted here today with my personal phone/battery accomplishments.
Hope this helps some of you out there because yes this phone can be known for terrible battery life but it CAN be tweaked to SUBSTANTIALLY IMPROVE that life to high standards and keep up with the best of them!

On Stock battery - Kyan Rom/Ktoonez kernel (at this moment)

Seems about right. My phone is completely stock and if I really wanted to I could even use it for 2 work days. I usually charge it over night though. I used it for 2 days though while at work, and with 3 hours of screen on time I was down to 7% battery. Around 40 hours on.

I was stocked rooted using Sammy kernel. On demand BFQ. I'll try on demand noop and see if that helps. My screen was about 35% brightness.

Can I hijack a little here? My battery seems to be atrocious. It was okay stock after my first 3 full charges I was getting about 12 hours and 2.5 screen time.
Here is what I've done with my phone since:
Flashed to debloated stock Rom
disabled remaining unneeded apps (example ATT wifi app)
disabled Wifi
disabled bluetooth
disabled GPS
disabled GPS autorun states
disabled 4g
disabled autobrightness, set to 15%
disabled location reporting
disabled Push email with Exchange
disabled Motion
disabled auto google backup
disabled keytones and vibrate on all button presses
disabled touch key lights
disabled Svoice
disabled streaming on googleplay, only plays from memory card
disabled Google Now
fixed the cell standby bug (even though it may not impact battery figured wth)
Uninstalled FB
Set all Autosync accounts and email to sync only once per day
No widgets (only Google play music, Smemo note, flashlight, and folders)
Running save power mode for low power screen, no haptic, and auto adjust screen to blacks
Running mostly black wallpaper, No live wallpaper.
Running medium intensity vibration
I ran battery stats and got a lot of wakelocks from googlemaps and exchange so I disabled the push email and set it to once a day. Google maps I disabled latitude, and shut down the autostarts with gemini.
It's getting to the point where the phone is basically a dumbphone just so the battery can make it while it sits next to me at work. Today I have 48% after 8 hours and 50 minute screen time and 20 minutes of google play (only playing from on SD card not streaming).
Any ideas? It seems like I'm getting less than average.

All I did was also flash debloated rooted stock. Set to top out at 1.5ghz power save on. On demand BFQ schedule. Screen brightness as low as I can to still read. And got 32ish hours. I'm going to try OnDemand and noop like the other guy said and UV a lot more and see how close to 40 hours I can get

Can u link me on the bfq? Having troublefinding what that is.
Also, is that the built in power save that limits the processor or some other software?

I believe if you flash Sammy kernel it has bfq. I am on task's CM10 and kernel and battery life seems poor compared to CM9 or stock rooted

Stop dimming on low battery

Is there anyway to stop the phone from dimming on low battery? I just got a Hyperion extended battery and it tends to last forever at 1% since it hasn't figured out accurate drop rate yet. So its frustrating to have my phone on low dim for hours.
Thanks.

You could try AdjBrightness from the Play Store. Might be outdated and not work on the Note 4 but there are similar apps related to it like RootDim (phone needs to be rooted for this).
Other way to do it requires permanent root and modifying a system file to shut off auto-dim and low battery warning. Same goes for warning when setting volume to max for headphones, bluetooth, etc.
I know which file it is and will modify it once we get permanent root. Most custom ROMs shut all these and warnings off so we don't have to modify it ourselves.

Under power saving go to restrict performance and uncheck screen output

Question Poco f3 screen flash when swithcing between apps

Hello, I'm a long time lurker and a new member here. I bought this phone a week ago and I have a strange issue with it.
Honestly I have no idea where else to look for help, I've asked in several posts over on reddit and fb to no avail. I'll try to describe the issue to the best of my abilities.
Anyways, I've noticed that when I switch between apps there is a momentary flicker or increase in brightness of the screen. I searched for a while and found that the screen refresh rate drops to 90hz for a moment and goes back up again. I tried setting the display to 60 hz and the issue disappeared. I tried setting it to 90hz with SetEdit and the brightness increased a bit. As if the brightness setting for 90hz mode is a bit higher than 60 or 120 if that makes sense.
I have 2 videos below one in 120hz mode and the other in 60hz. The camera exaggerates the effect a bit but it's visible with the naked eye in low to moderate lighting conditions i.e indoor use.

note that in 120hz mode the refresh rate drops to 90hz for a moment.
Is this normal or do I have a defective unit?
Thanks in advance

As for the Hz drop, this is normal when using this phone because it offers adaptive refresh rate (drops from 120Hz to 90Hz when you switch between apps). As for the flicker/brightness change, it does this to me too so I am guessing it's either a bug or just a result of the implementation of the adaptive refresh but can't be sure about that.

Sorry for the long delay. I am pretty sure you can follow this tutorial for this:

It ain't permanent... Just switch to any aosp rom. I'm tired of ****king memeui.
I installed it for performance and convenience of many more features but dumb stuff like this is unbearable at this point. I've tried many more stuff other than this and usually just downloading setprop app and changing user_refresh_rate value to 0 disables refresh rate switching. But only for a while , doesn't survive reboots and locking screen or opening certain blackilsted apps like mobile legends and such that are hard locked by miui at certain screen refresh rates....
Do yourself a favour and uninstall Miui
