[Q] my battery is still draining fast after rooting! help please?

hi guys, i'm a newbie when it comes to rooting and stuff
i reduced all my lcd settings (display is only at 10%, removed animations, etc), turned off unecessary apps (wifi, etc) and i'm using setCPU (so i could downgrade my cpu speed) after i learned how to root here with the ff settings:
cpu range 200-500 mHz, conservative.
my phone still seems to be draining fast. i'm not watching vids or playing games.
can anyone help me or give me tips which overclock actually worked for their S2?
i was hoping my battery would last about a day.
thanks!

Suggestions: restore your cpu settings to normal to establish a base line. Then download Osmonitor and see if any application is hogging your cpu. If not, then, in recovery wipe Dalvik cache (not anything else!).
You don't say what rom you are on but assuming you are not watching video files all day, you should get a full day easily.

Is your device connected to an exchange account ?

Root has nothing to with battery life directly, but you can use T.B Pro to freeze some garbage apps always.
Besides you can't get any benefit from using SetCPU? LOL. Well I don't wanna a debate here, but that damn app will not do any useful thing other than mental satisfaction.
And you stop any app which is set as Automatic refresh in an specified interval, run as low as Widgets possible, Turn Off WiFi and Packet Data when not needed, and try to use Juice Defender which is doing a great job on mine.
Regards.

thank you for the replies
@tangiers: can osmonitor also freeze useless apps? or it just merely monitors your phone?
@jimhaddon: what is an exchange account? i don't think i set-up anything like that while i was tinkering with my phone.
@ithehappy: i think i'm only getting the mental satisfaction from setCPU like you were saying

I beg to differ. After I isntalled SetCPU and Underclocked/Undervolted my CPU I found that my battery life increased quite a bit and was no longer experiencing battery heating.

I9100 CPU is smart enough to change it's state when needed, you don't need an additional 2US$ software for that, when will people agree this fact? Anyway, why shall I care!

I'm also in the camp that thinks setcpu is a myth for saving battery. The cpu already scales up and down as needed stock. At idle the cpu sits at 250 mhz.

SetCPU
I found out that setCpu actually drained my battery faster, so just uninstall it.
See if it gets better.

My battery drains too.
Solved that problem by charging overnight.

There are many factors that's can cause battery drain, wakelocks, signal strength, method of data wifi or 3g, display etc etc
You could have a rouge app that is keeping your phone awake, download betterbatterystats and check for partial wakelocks.
Signal strength can be a factor, see your current signal strength and then change the modem to see if this reduces.
No need to tinker with setcpu, you can underclock if you wish but generally leaving it on stock is fine.
Most importantly enjoy the phone don't get to obsessive with trying to save every ounce of battery its a smartphone at the end of the day otherwise we'd be carrying Nokia 3310s with us, and remember you can always charge nightly!

Things that drain the battery :
Gps
Bluetooth
Wifi
Life wallpapers
Display brightness
Display time up setting
Try to configure them and see how much you can squeeze that .
Check on setup battery the top ranking of battery usage.
This is mibe so you can compare :

See my screen time above. I feel its pretty good. 6hrs+
I underclocked to 800mhz, auto brightness, ICS stock rom with the famous KH3 modem. The phone looses 2% over 8hrs of deep sleep. I think thats awesome. My phone lasts for at least 13hrs. (I charge it overnight and take it out @ 6am and use it till 11pm.)
Off topic: I was using my dad's iPhone 4 for a while and the battery life is amazing. But I still hate iphone.

since you are rooted, try flashing jeeboo kernel
other tips, if you are not using Google Now disable it, freeze samsung push service, settings -> wifi -> advanced -> network notifications - uncheck.

Poor battery life

http://i.imgur.com/HuW8tQu.png
I hardly used my device at all and in three days the battery had been reduced down to this.
I'm running stock and I'm using mkernel. What's the operating system doing when my device is idle to consume all that battery life?

Most likely location based services such as Google Now.

Battery life looks pretty good to me. Idle is not off. If you want better battery life, turn the nexus off when not in use.

No, and it's not recommended for this kernel. You probably have some application using the CPU. And keep in mind, that's over 3.5 days, so it's not too be worried about.

Not really sure what you are looking for.
Your tablet is configured differently (read: installed apps & their settings, never mind ROM & kernel differences) than the next person's, and those configuration changes alter the activity on the device and therefore the amount of power it consumes vs time. If what you observe is unacceptable to you, you need to drill down into the details to try and optimize things. But it really is impossible for anybody to guess (from a completely blind position on the other side of the internet) what might be the cause; if that is indeed anomalous consumption compared to some benchmark (pure stock, no market apps installed & a dormant gmail account?), the cause could be due to an unlimited number of different causes.
Perhaps you want to use that app BetterBatteryStats ($2.89) to find out about wake lock usage.
FWIW, my rooted stock 4.2.2 N7 grouper tab seems to discharge about 4% "overnight". Call that 10 hrs or so, so maybe I should expect 10% discharge per day while idle and unplugged. Your result seems to suggest 16%/day; but I've made no effort to dig in to things on my end of things - and besides: my results are irrelevant to yours as I no doubt use a different collection of apps than you and possibly different settings for the stock apps, too.
In my case the idle drain rate isn't a very compelling use case - I use the tablet every day, and when it is idle it is plugged into its' charger. If it should happen that it sat idle for a couple days, it's gonna be at 100% when I decide to use it.

And the problem is?
Around 6 days of standby, and you want to improve that?
If you want to improve that, turn off your tablet. I'm sure u can spare those 60 sec two times a day you turn on your tablet to check mail.

Keep WiFi off when not in use and you should see a great improvement. I use stock kernel and over that same time period my battery is about the same with about 3 hours screen on time. I only turn WiFi on when I'm actually using it as anything I need synced goes to my phone.

Try better battery stats and see what keeps your cpu from going to sleep state..With this way you can examine what drains your battery my friend.,.

Try turning off auto-sync. (Data usage settings)
Never keep wifi on when sleep (you will lose notification to chat programs, social network app notifications when sleeping)
Use wifi powersafe mode.(Wifi advance settings)
Turn off/disable unneeded background update/apps/extensions/services and flash a rom with minimal google stock apps)
Of course, check for apps that are currently consuming power if any. (App settings, internal application setting)
M kernel also defaults cpu max to 1500Mhz ; stock is 1200. M kernel also sets gpu to 446Mhz ; stock 416Mhz. Altho this numbers might seem minimal, it can affect your battery life considerably shall there be background processing or even right after you start using your device again despite minimally in your case. (Use n download trickstermod)
These might or might not help you in getting more standby time, try and experiment =>
If you are also looking for more screen on time and if you know and accept the risks, you can try undervolting the cpu, gpu and ram in trickstermod, you can also use rootdim to go lower the screen backlight further, but do not go lower than value 4/255 as that is 'off'. thankfully you can set it to not go below 4 in the in app settings before you play with it. My configuration pushed to 8hrs+ screen time without any gaming =>
Do note that li-ion/poly batteries need to drain over time for batt health reasons. They generally last longer if kept in the 20-80% range. Room temp can also affevt battery drain significantly, cold < 26C room drains the batt real fast; and so does hot rooms >34c due to temp & conductivity relationships (batt needs to suply more due to less conductivity in the circuits when hot)

[Q] Fast battery drain, Ram usage related ? General tricks/tips please :)

Hey, My battery doesnt like being used, It kills itself, During normal use, say, just having the chat app Line, open for 20 minutes chatting away, on auto brightness, the battery often goes from 100% down to 85%.
I dont think this is normal, but correct me if i am wrong..
And I see stories of people saying 'my battery drains fast overnight!'
Well im sure that if i left mine without plugging it in overnight it would drain flat LONG before morning....
Im wondering if this could be related to RAM usage at all, Because even though im on an AOSP based rom, My ram usage is always arounf 1-1.6GB
Or if not that, What kind of things could be causing my issue ?
I tried the battery section of settings, and it usually says screen uses all the power, But sometimes, on low brightness, with 1-2 apps running (im the kind of person that closes what he doesnt need)
the battery monitor widget reports a drain of well in excess of 1300mah D:
Battery life is very important to me as i only really have a single chance per day to charge ;___;
Any advice on what I could do is appreciated c:
Im fine with disabling cores/underclocking or any other [major and efficient] battery saving tricks.
Phone info in my sig.
tl;dr: help me save battery. does ram use much power?

afaik, RAM usage isn't battery related. As usual, unused RAM = wasted RAM.
Perhaps you have insane wakelocks or apps that run in the background that automatically updates itself hourly/something. (E.g., Facebook updates itself hourly by default)
If you happen to be rooted, you should try out the apps Greenify and DS Battery Saver

Using Auto Brightness will cause using more battery, use BetterBatteryStats to check what's using your battery or maybe wakelocks

Thanks guys! Ill check those apps out and post back with anything i find!
Edit: Okay, I tried them, Didnt like them and they messed with my push notifications :c
I also tried something I saw else where, that said to flash the chronic kernel and cap the cpu at something lower, so i have it locked at 1.2ghz...
But my battery still seems tr drain at the same speed D:
that battery stat app I cant figure out..

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.

My battery life goes way up when I put the phone in the glove box of the work truck. 0% drain over 5 hours, checked it for call a few times and that was it. I leave data and stuff switched off until I'm going to use it.

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)

S7 Edge Carol Blue Snapdragon CPU Around 30% at rest

My phone is not even one week old and it lags like crazy. Especially when I put it down for few minutes and pick it up to open a notification. Even scrolling up and down stutters like crazy for a new phone.
I noticed my CPU is always above 30%. I have ZERO open apps in the background and this is the lowest the CPU gets. That doesn't seem normal to me.
I'm using System System Monitor app to measure. Can someone please install and confirm what you are seeing on your S7 Edge please? I am in the snapdragon variant.
https://play.google.com/store/apps/details?id=com.dp.sysmonitor.app

Also, shouldn't I be seeing 8 CPU cores instead of just 4? What am I missing? This is an Octa Core phone, I'm only seeing 4 CPUs
Please advise on what is showing on your phone. Appreciate it.

What version of S7? Snapdragon (US versions) has quad core. Exynos (International) is octacore.

Erase your cache memory in both Settings->Storage and via the recovery menu (hold the volume up, home and power keys at the same time from a powered off phone).
If those don't help, might need to try a factory reset and start over.

Just downloaded it. Also Snapdragon, Blue CORAL. Been watching it for 2-3 minutes, and it's around 30% at rest, all apps closed. Saw 29% once, but mostly 30-33%. I have all the latest updates, Verizon. I have no noticeable lag, at least compared to my Nexus 6P, and battery life is just awesome.

Funny me and you have the same exact setup even a Nexus 6p. I find it very strange that CPU at rest stays around 30%. CPU Usage on my 6p at rest is around 2%. I really thought my phone is defective.
I'm interested to see what other s7 edge folks report for CPU Usage at rest.

Just started the 6P back up and installed the app. Yep, much lower, once it stabilized. About 10% average. But the battery life is so good on my S7E, that I don't think there is a direct cause-effect here, since our stats are close to the same. There is a warning in the description of the app saying it doesn't run well in all MM devices.

I am convinced now that this monitor app is not really reflecting correct CPU usage on S7 Edge.

you guys s7 edge uses performance govs and uses hotplug to control cores. That is why your cpu usage is sky rocketed currently. Root change gov and than it will not happen.

Thanks, but I'm not rooting this phone. First time I've not rooted an Android, and I've owned Android's for a lot of years. Rooting can bring it's own set of issues, like making upgrading more difficult. And the CPU usage, if the above app is correct, is not impacting my battery life at all. I unplugged it last night when it hit 100% charged and it was down to 98% 7 hours later. I can live with that.

I don't belive that CPU app is playing nice with s7e monitoring. I'm not concerned anymore. Think this phone is alright.
