Reason for bad Battery life, sticky 1026MHz?!

So since I had my nexus 4, I had to complain about its terrible battery life.
I would never get more than 3h of screen on time, despite my best efforts in conserving battery. Even with the phone in flight mode and on Wifi, I could not cross 3h give or take a few minutes. I even tried disabling location, google now, sync and everything else.
It was deep-sleeping nice, while the screen was off, standby time was awesome for me. If I turned it on though, it started to burn through battery insanely quick. So I started monitoring the frequency states with battery spy, and noticed that as if there was a little load, it spiked to 1026MHz and then stayed there for about three seconds every time before falling back to 386 MHz. So I tried setting the max cpufreq to 916Mhz with CPU tuner, and was astonished to find out, that immediately after the load was done, it went back to the lowest frequency. Like it should be, not hanging for multiple seconds on the high step.
Also, If I start CPU tuner, the min freq is always shown as 1026MHz. So I changed min to 386 and max to 916. Afterwards, this stays until I swipe cpu tuner away from the recent apps list. If I start it again, the settings revert. Strange...
With my cpu limited to 916MHz, I get about 5h and 50 min of screen on time without any other measures. Location on, Wifi on, Google now and sync all active. If I just go one step higher and set my max frequency to 1026, the old behavior starts again, and screen time drops to 3h because it seems to be stuck on that freq. Therefore I would like everybody who also has bad screen time to try that out and report back.
I don't really understand why it would take so long to drop back from the 1GHz step, and drop back immediately from the 0,9GHz step?
Of course, this is with normal surfing via chrome, or using normal apps that are not that much CPU intensive. Also, you hardly notice the performance limitation without playing games. There probably is an easy way to fix this?
Feedback would be appreciated. Maybe I see this wrong...
Thanks
tl;dr : if screen on, for me only 1026mhz is used, if max freq is set to anything lower, the phone spends most of the time at the lowest step 386mhz, greatly increasing screen time for me.

Flash Franco Kernel and buy the app and you'll be set.

Maybe, but I really first wanted to examine out of the box behavior

This is caused by qualcoms Mpdecision which ramps up the cpu to 1ghz on screen on and touches. All in the name of speed. It's basically a hot plugging technique such that smoothness is guaranteed under loaded gui transitions and scrolling. Before this you would have to wait for the cpu to be loaded for it to ramp up speed. Now the OS can demand speed.
You can see in Franco kernel he replaced Mpdecision with an open source alternative and swapped the lowest cpu speed to 368mhz. Then added a load step of 768mhz (for 60% loads). This actually added a bit of lag but should be better in the battery department. Some more tweaking to be done though.
Qualcoms thermald is what is causing thermal throttling.
Edit: this could be wrong. But I think I'm in the general area of what's going on...

This does sound logical, but why the hell waste nearly half of the possible screen time on "perfect smoothness" when even if limited to 0,9ghz everything runs pretty amazing... I will look into francos kernel, even though I dont like to buy an app to tune it,

You don't have to buy an app, everything can be set through scripts. The app just automates the process, allows you to back up kernels, download the latest nightly and milestone (when one becomes available). It's really worth the investment, plus you're helping out a great Dev who has shared his awesome work with us for a long time.

I like my phone to sleep. I bumped it down to 384!
No need to keep it @ the 1.026, it will pretty much kill battery! Makes no sense to me.

You can set the max to 384 mhz.. and still everything is smooth

Can I use SetCPU or is that app defunt now? And to change my CPU speeds can that be done on a phone that's simply rooted or do I need a custom kernel?
EDIT: I downloaded CPU tuner, but I'm not sure if it's working or not. Does it work w/ stock kernel or no?

Faux's Intellidemand fixes pretty much what you're describing. Since mpdecision is not used instead of fauxs alternative.

What is max frequency by default?

Have to say firstly, that the perfect smoothness of this phone is what has sold me on it as the camera is well below average, it has some bugs and the output quality and volume of the audio is shocking, but it is the single smoothest phone out there.
Get rid of what I came to know as Touchboost (feature brought in in jelly bean to introduce the lag free experience of project butter I imagine) from my Sgs3 days, and the phone becomes as laggy as every other android phone out there.
Secondly, I get around 3.5 hours screen on time, without messing about, wifi on constant, depending on whether i'm on the net or not, I can get more.
I find AOKP perfect as its super fast and battery is excellent.
Franko kernel works, but the phone then feels choppy. Setting the cores to 1ghz makes the phone laggy also.
All I can say is, get lots of chargers, I have two at home, two at work, one in the car, one at the other halfs, and it's trickle charging when and if I can and I never worry about battery anyway. I find it wastes far too much life.
Good luck.

Thank you for not contributing to this thread with that useless comment. The rest of us may not want to charge the phone 1500 times a day (or are even able to), and are looking for ways to help battery discharge go slower while using the phone. If you're fine with charging your phone nonstop, then what are you doing in this thread? Everyone knows you can buy many chargers, that's not a solution.

Welcome to Project Butter. If you want to do something different than Google's goals for UI smoothness and responsiveness, which is what everyone has been complaining about in Android vs iOS, then you'll have to go the custom ROM/kernel route. Thankfully that is easily available to you on this hardware and software platform. Me? I like the N4 just fine the way it is stock.

Dude, this has nothing to do with googles project, but instead with Qualcomms responsivness "fix". Please read the answer to my inital post, and you will understand. Also, the phone does in no way feel choppy if you restict it to .9ghz. Except if you load it so much, that it cant cope with this max frequency. But then again, this is not the issue, but the issue is, that 1026 stays active for to long, so that it burns through your battery. There would be only a small change needed to change this behavior, and "possibly" loosing about a fraction of a second of responsivness, that most of the time you wouldnt even notice... Everybody who tells me he is happy with barely 3h of screen time or even less is just the android equivalent of an isheep, because this is in no way acceptable.

What kernel are u using? Im using franco kernel + latest CM 10.1 nightly.

My min CPU speed is 1 GHz and in still getting 4 hours on screen time though. I don't think setting my min at 384 MHz even made much difference in my battery, will try it again soon.

Stock never rooted bootloader still locked.

If you are getting bad battery... simply flash a custom kernel. You get to keep your stock ROM or whatever but you will get substantial benefits. I prefer Trinity Kernel. Only the second or third update on this kernel and now the phone has made huge gains in battery life. Like hfm, I good on screen time... usually 5-5.5. I have auto brightness on, mobile on 100% of the time, and all Google services synced including books, gmail, currents, google now, etc etc. I have locations on, gps on... everything. Sometimes I turn off NFC because I rarely am somewhere where I can use those cool RFID card scanners. What sucks battery is probably a problem in Android 4.2. The phone does not sleep as much as it should. Go ahead and turn all your sync stuff off and keep the screen on static and let the battery die at stock clock speeds. Probably will get at least 5 hours with auto-brightness on. My phone probably sleeps 60% of the time now according to CPU spy when it sits idle in my car for my 8-10 hour work day. I usually get to the car with a bunch of emails, a text or two waiting for me, and the phone has only been asleep the aforementioned 60% and around 90-91% battery life. On a new phone, starting from full charge, this should be at least 95%. My N10 that doesn't have mobile data, only loses about 1% overnight. Apples to oranges but still. I'm convinced that stock voltages on this device are too high, and that Qualcomm did not give Google the latest drivers... maybe because it's not releasable to AOSP as of yet. I really don't know, but it's gotta be something buggy. This SoC is capable of doing better... and it does in the Optimus G and even with sense, 1080p screen, and a 100mah smaller battery the HTC Droid DNA/Butterfly gets 3.5-4 hours stock screen time. None of the other phones using the S4 Pro are running 4.2. I'm hoping either Qualcomm pulls a Samsung and releases some updated drivers/firmware that Google can incorporate or that Google fixes whatever bugs they may have not worked out. In the next calendar year other phones will be out that use the S4 Pro and 4.2 and I doubt Qualcomm wants to lose the luster it earned with the regular S4 Kraits performance/efficiency. When 4.2 comes to other devices we will probably know whether or not Google is to blame for this or that the Nexus 4 is just a poor performer.

Galaxy s5 SM-G900V OVERHEATING/BATTERY DRAIN

So, I've had my GS5 since release since last April; and for about 3 months now, its been overheating and draining the battery, I've contacted Verizon and they've given me a replacement phone and a new battery, but it still continues to overheat, hottest I've ever seen it get is 76c and that happened just today. So i tried resetting the new phone to factory and then re-installing some apps. it still continued to overheat. Then i tried going without an SD card, still getting hot (when the 76c happened) . I looked at the battery manager and it says that Android OS and the Android System were using the majority of the battery. I'm out of ideas, any of you guys have anything i can try?
Thanks in Advance
Attached is a picture of a CPU Temperature monitor about 2 mins after it was booted without an SD card

CPU usage & frequency looks pretty high, or was that just because you were taking a screenshot?
Does it drop back down to idle when you leave it for a while?
For comparison using the same app, Im getting 29c with 5-6% CPU usage idle

I cant even remember the last time i saw 30c on that cpu temperature, my phone idles at ~50c with an extremely varying load (spikes up randomly and back down) even when its in my pocket and not in use. It never drops down CPU usage is always mid-high

Id check what's using the CPU with one of these

Ultimate Battery saving solution Thread!

Hello guys,
I have been researching, experimenting and trying many many things to understand how cell phone battery consumption works and how to find the solution to be able to use the most of the battery! HTC did a very bad job on the battery side of M9 and in my opinion, Battery is the only downside of M9. I will explain later why I say that.
I will share the tips and tricks I found to get such battery life that none of you ever think of getting out of M9. Look at below battery stat. It looks like M8 battery stat which made all M8 user really happy with their device! Now we will be enjoying that too! BTW This is my birthday today, so its a very good day for me to post this thread. Wish me luck!
First Let me explain some things about why a phone drain the battery in relation with CPU and Apps.
1. Random CPU freq change.
2. CPU heat.
3. When phone is idle, means you are not doing anything(not opening apps or neither you have apps opened in background, CPU freq not being able to stay down.
4. GPU related drains(while playing games or not)
5. Display category. Amoled or LCD or what type.
6. Buggy ROM keeping wake locks. ( I am not going to talk about wake locks at all. There are good enough threads for this)
7. Apps. Each you open and close an app, the cpu starts working, freq goes high. So, this means, the less opening and closing you can do the less battery you consume. Now, all these concepts of app killer running in background, killing apps after a certain interval, ARE COMPLETELY WASTE OF BATTERY AND NOTHING ELSE! Android keeps opening apps in background according to its algorithm. So, if you want those app to stop bugging you in the background, then task killers are NOT ANY USE AT ALL! Remember! The less app in background the less drain you will get. We usually use home button a lot when coming to home screen but we dont realize the app just got minimized and consuming as much as battery as it would if it was open in the foreground. So result is, bad standby time + more drain while screen is on.
So how can you get rid of those background apps? Best way is to use Greenify. Greenify is the only app that can hibernate any app without hogging battery by itself and keeping wake locks. How to find which apps to put under auto hibernation list? You need 2/3 days to observe. Greenify will automatically mark those apps which opens in background. Once you are with good number of apps, greenify all of them. In greenify settings, select autohibernation so that even if some gets awake by the app, can be put to sleep again. Now two things will hapen because of this.
1. You will consume MUCH LESS CPU power means you will save battery. The device will be very snappy. Ram will be at least 1.3 gb free.
2. It will take more time for an app to open which are under your hibernation list. Now I have thought about it. My conclusion is that, I need to choose between battery and super fast device. When I on battery saving priority I follow the solutions of this threads and when I am not worried about the battery I try to enjoy the device.
So, we can restrict apps from hogging with greenify. Now how to control the CPU?
Out CPU is actually ULTRA FAST and is capable of fastest performance amongst all smart phone around. Here is the antutu benchmark to show how crazy this CPU can be! So crazy CPU will drain battery. Its cor-relational. So, the solution is to limit the CPU from putting too much power, especially when it gives more than the phone and user needs. When I was using HTC Sensation, I was feeling like, there are 2/3 things which should be better and I demand nothing more from a phone. LIke battery, camera, ram etc. But after M7 I have never felt that the phone should get faster and we should get like 4 gb of ram either~! But newer means faster and better. So CPU + GPU are getting more powerful and eventually the phone is getting such overrated power which it doesnt even need! After all we are not flying to moon with our phones! lol!~ Right?
ok Now how to limit the CPU?
We need
1. Elemental x kernel 4.01 installed with all stock configuration. This is important. Yout must use STOCK values. I have seen anything else other than STOCK values drain the battery even more! So STOCK IS BEST!
2. Elemental x kernel app or Kernel adiutor kernel config app to tune the kernel for our battery saving mode.
Steps-
- Set HTC pnp manager off
- Set max cpu freq of small cluster to 864 mhz, min cpu freq to 384
-Make sure you are on stock gov.
- Set GPU max to 320 GHZ.

Disclaimer: These settings will make the phone performance slower but not laggy. So, just consider a power saver package which has very decent speed too!
After applying these settings, you better restart your device to let settle it with new rules for CPU. leave the phone for 2/3 mins. The things that you will notice when you turn on the display -
1. No rapid CPU freq changes
2. Phone is ultra cool as the temp of CPU and battery has gone down to 35 C. M9 with default setting will never come down to 35 c ever! The lower temp would be 40 c. So, cooling the cpu will minimize mA consumption.
3. when you open any heavy app like fb or chrome you will see the consumption mA rate is almost half of what it is with default settings. Max rate of discharge was 700 mA for me with 50% brightness + 3g internet + FB/chrome/youtube.
4. When you leave your phone to sleep, here is the fun! I have never seen such low mA discharge rate on M9 and I didnt even expect! It goes as low as 40 mA! Insane! The avg screen of discharge rate I found was 70 mA which means on full charge our M9 will get 40 hours standby! And that is with internet on.
5. If you are charging with official m9 charger, you will see the charging rate is 850/+- mA while your display is on with internet. When screen off it will reach mac to 1340 mA. My phone previously was charging at 600 mA with screen off. So, now 0 to full charge is only in 2 hours.
6. Clash of Clans used to drain 1200 mA and now it drains only 550-600 mA.

Instead of turning PNPMGR off, have a look at this first. http://forum.xda-developers.com/one-m9/development/mod-htc-one-m9-enhanced-thermal-t3369574
It's a pretty indepth thread on the pros and cons of PNPMGR, and also custom thermal configuration files that change clock speeds of your CPU, dependent on your usage.
Also, your Antutu benchmark picture isn't anywhere to be found.

What about CPU boost? Do you disable it?

I do all like u but my m9 is still after few minutes too hot.
I never was more diaappointed with any another of my phone and heating and poor batt life like on m9...
After one hour of browsing internet I'm over 50% down.. on stock mm. That's shame for HTC. Now I'm back on my 2yrs old s5 with still perfect battery life..

I don't get any overheating on my m9 at all. It's on stock marshmallow still. Bought it used a couple weeks ago.

Hi,
If you did an OTA update to MM and are losing that much battery in just an hour of heavy use, then I would back up everything and do a factory reset. I can go for 5 hours of very heavy power user performance before dropping to that level. Either that, or you have a malware app on the phone that is being used in the background. Which a factory reset will also solve.( except in rare cases, requiring a firmware reflash)

Rooted Battery life worse than stock?

Hi xda family
What has everyone's battery life been so far on root?
Preroot I was getting over a day with 6sot and 16 percent
Android drain.
After rooting with the eng kernel it has dipped a lot with high android system drain. Have not used amplify and greenify yet. Just been used my tweaks I did on pd7 kernel.
Thoughts?

Amplify will probably help out a lot. I've seen others reporting the battery is worse after rooting as well. Hopefully someone nails it down and posts a fix. If not, I'll see what I can do once (if) I decide to root.

Yeah I can literally watch my battery % drop after root. I noticed 46% of use is the android system. I'm also getting lots of random reboots.

You guys rooted with an EngBoot that was not intended for daily use, this is one of the side effects.

Yeah the ENG-BOOT is a terrible way to achieve root. I really hope that this tiny victory doesn't cause people to stop looking for real root. The ENG-BOOT is not meant for daily use is going to cause lots of issues, it's designed just to push fixes to the system for an authorized repair shop.
The focus should have always been on the bootloader.

Wow 46 is high. To be honest for eng kernel it's been stable. No lag and reboots for me. I am debloating and doing a few tweaks and making it settle in some more. If I can get to 4 sot I will take that.
Also I have heard if you your governor set to on demand it will cause reboots. Using interactive and been solid.

I was able to get 5 sot and 1 day of usage. Android drain was at 14 percent.

I'm reodining because it was suggested to do when updating to texhd 1.5

dam we got root now? I didnt even know

With all the different tweaks now available through root, the battery life is quite excellent. The only concerning thing is how hot this phone can get at times (after a reboot, gaming, downloading an app) that I may be doing great harm to my batteries life in the long run.

okay so,
the engineering kernel's default governor is performance and that's the only thing that's causing the heat issues and thus, the throttling of the CPU cores to lower frequencies resulting in lag/stuttery performance. that's all you're experiencing. thinking that apps are using more/less battery than usual is silly.
after wiping data and cache and going through the horribly slow setup process, I used kernel adiutor to change the governor back to interactive (NOT ondemand) and let the phone finish settling/syncing. after 2 days, it's back to its silky smooth performance and all-day battery. I don't see anyone experiencing anything other than symptoms of the performance governor.
btw, it took the same amount of time for my phone to stop being laggy when I first bought it. so literally all you need to do is change your governor back to interactive if you want the performance/battery life you had before, and zero heat issues. antutu scores 110k-138k depending on temperature/throttling. just like it did before. battery gets 4:30-5:30hrs SOT just like it did before.
TL;DR

I used kernel aduitor too till I found out my big core were maxed at 1500 also just like the little cores and you can't change those with aduitor.
Once I installed kernel toolkit, I confirmed it.
So I bumped up the big cores max and got much more speed back. No heat here
Food for thought.

Only get ~2 hours of on screen time - "Android System" battery drain

I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.

Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.

Still on 6.0.1 & Android System is my #1 battery drainer.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.

If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.

Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.

Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.

So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

Disable ubication and always on display.

I use AOD all day, one of the reasons I got the phone. Not willing to part ways with it lol
ubication?

I mean location. Aod takes almost 40% of battery in 24 hours.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.
