Battery savings guide

Hello, i use Dalingrin's kernel (6/30) and CM7 nightlies (121 currently).
Sometimes deep sleep is nice for my battery, sometimes it doesn't save energy.
It's life but i need a few days between battery charging.
so i decided to add a few workarounds, here they are:
1. Airplane mode everytime + wifi on/off when i need it. Only ten seconds to activate/deactivate with CM7 status bar.
2. Battery widget monitor: it enables history of battery consuming. Very good to act that deep sleep is effective or not.
3. uninstall applications which sychronize when nook should be sleeping: K9, DSPmanager, hotapps, appbrainz.
3. Advanced task killer pro: Crazy mode when screen is off. Very nice for last applications.
Of course, you are welcome to comment those tricks and to add some

I guess it depends on use, but I'm on day 3 on a charge, running at 47%. I just have the screen at 15% most of the time, and I don't disable sync. I mostly do reader, email, internet, so that might be part of my success.

1 is probably not a good idea, since sometimes Airplane mode sticks.
2 has nothing to do with saving battery, but okay..
3a does nothing if there is no network connection (assuming sanely written programs)
3b is stupid and shouldn't ever be used.
You want to save battery? Turn off wifi when the screen goes off. You can do this automatically with Setting Profile Lite or Tasker, probably some others. I've found that the wifi sleep setting doesn't do anything for me, I can continue to ping the NC for 10+ minutes after the screen goes off so clearly the wifi is still up.
And watch Spare Parts partial wake locks and see if you have any misbehaving apps. I find that Maps with Latitude enabled misbehaves without a network connection and constantly is trying to update or something, so I cleared data on Maps to get out of Latitude on that device. CPUSpy will also show you how much deep sleep is ongoing.
The NC is going to use at least 10%/hr at low backlight doing simple tasks, I've seen it use up to 25% overclocked playing games.
While asleep it uses about 1% every 3-4 hours. Could probably do even better if you don't have a boatload of apps and widgets like I do.

Grab "Where's my Droid's Power" or whatever the application is called, and see where all the power is going.

He said the battery widget is to see if it is asleep, and see what the consumption is like.

Hello,
You are right about battery logging.
i have to test the two applications you mention both:
1. "And watch Spare Parts partial wake locks and see if you have any misbehaving app"
2. "Where's my droid power".

Battery drainage on Galaxy Note

Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.

That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.

I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.

Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.

Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though

No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air

I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity

Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.

Deep sleep problem

Hello world,
I just noticed this disturbing issue. I lost about 16% battery in one night. When I looked at battery state I noticed alot of tiny little wake moments during the night.
What kind of application can cause this? Or are there any known bugged apps that cause this?
Wakker is dutch for Wake

. THE Galaxy Notes when goes into standby (screen off) should go into deep sleep mode is a mode that allows you to keep to a minimum processor frequency to conserve the battery. Unfortunately, between the various firmware updates that we do and the various programs that we install (some of these work in backround without noticing it) can happen that the Note is no longer able to enter deep sleep mode remains fixed at 200mhz even while on table with display off.
To find out if our notes go into deep sleep, just install the free CPU Spy download here: https://play.google.com/store/apps/...wsMSwyLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ..--- If your notes do not enter into deep sleep the greater the percentage occupied by the item above, or 200mhz.

It happens so that at night, leaving the device on but without the latter is used, however, so battery consumption (having remained fixed at 200mhz) and the following morning surprise that we find the percentage of low power.
To overcome this problem needs to be done in the following way: Deep Sleep Guide
- Go into settings and remove the following tones: sound freezes the screen and sound selection - Set the device in flight mode - Turn off the device - Remove the battery for 10 seconds - Power on the device - Wait until everything is loaded - Remove Airplane mode
And that's it. The Notes should regularly go into deep sleep after doing this guide. To check everything just to keep notes on standby for about ten minutes and see if The candidates and the percentage of deep sleep increases.

Hi
Even I face this battery issue....it is severe in my case. I hardly get 14 HRS of battery life even after about 30 charging cycles
I've installed CPU spy, I found that the CPU stays in 200Mhz, for testing purpose I had kept my cell phone untouched in flight mode for about 12hrs but still I lost more 50% of battery.
I had tested the battery by completely charging it, it just drains before my eyes . . .
I don't know if this is deep sleep issue. please help me.

Download BetterBatteryStats and look for wakelocks (partial and kernel). Google them if you don't know what they do. Then uninstall them or fix them somehow.

If you havin' battery troubles I feel bad for you son...

I got 99 problems but my battery life ain't 1.
How to get the best battery life out of your Nexus 5
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

4, 6, and 7.. it would all depend on your signal quality. i get MUCH better battery life on lte than on wifi. and i mean much! i get 5-6 hour screen on time without doing anything special. on wifi i get an hour to hour and a half less. so the wifi thing is just in your situation, and not for everyone.
9.. there are better kernels than franco kernel. and on top of that, kernels have so little influence on battery life. battery life is mostly about your personal use, your personal setup, your choice of apps used, and very much on the quality of your phone/data connection. everything else has very little influence, including kernels.

3. This I agree. I've had super strange battery drain if I don't restart the phone once in a few days. I refuse to believe its a bad app as there are no wakelocks, seems to be more of a phone idle battery drain or radio drain.
4. To be honest, it depends on the WiFi network. Some WiFi networks (typically at universities) have a strange and outright horrible battery drain the moment you connect to their network and leave the screen off.
6. Again to not repeat what I said earlier, I get better battery life if I connect to LTE instead of my school's WiFi. Download speeds over LTE are 2-5x greater than my school's WiFi, so race to idle may be happening here.
7. Most android phones today have minimal battery drain with WiFi left turned on. But it doesn't hurt turning WiFi off if there are many weak known WiFi networks around you.
8. Not sure how much you'll save, I don't even recall much of an increase of battery with this off. YMMV situation I suppose.
9. I've had better battery life with other kernels. Again it's a YMMV situation.
Not a bad guide really
Another tip is that if Google Play services keeps your phone awake for a long time, revert Google Search to an older version, reboot the phone. The wakelocks should be drastically reduced.

Using Nexus 5 with:
CyanogenMod Nightlies
ElementalX kernel
1d 2h 9ms on battery / 2h 17ms screen-on time / with 38% remaining!

Good information! ?
Only thing I'd say is to just remove the part about kernel completely. As said above, kernel makes little difference. I get 24 plus hours and 6 hours screen time on any ROM or kernel. It's all setup and usage.

Nothing new here. Good for noobs, but most will have done this already

I have found that turning location off completely has helped my battery life tremendously. While I was barely able to make it through the day before, now I can easily pass by with 40% or something and light usage. I've tried other things but nothing has improved my battery life as much as turning location off.

Yup! That's what toggles are for. Need it? 2 clicks and its on. That's always my advice.

[Q] Still chasing battery drain: Is it possible FingerPrint Unlock is part of it?

So having come from Verizon's Note 4 and averaging up to 24hrs on battery running pretty much the same setup as I do now on my T-Mobile Note 4 minus the "Root" & "Custom Rom" abilities. Otherwise, same apps, accounts, usage pattern, ect...
I am on an ongoing battle still after several complete wipes, different Roms including just running STOCK ANK4 and trying to figure out what is going on. Phone defect? Battery defect?
Anyhow, Ever since changing over to both the T-Mobile Note 4 & their service, my experience has been a rather miserable 14 to 18hrs MAX battery life and going from 4hrs screen on time to around 2 1/2 w/ T-Mobile.
Which now leads me yet to wonder something else. I believe I started using the "FingerPrint" security feature since switching to T-Mobile to unlock the device. Has anyone experienced a similar "Battery longevity" issue using said feature before I continue troubleshooting and chasing my own tail on this? Of course I will eventually test this theory anyhow, but figured I would throw it out there.
Also, Open to any suggestions.
Just some things I have already done along with the above mentioned:
- Utilized the App "Greenify" & donation full version to greenify many apps including "Google Play Services".
- Set up Profiles which I toggle via "PhoneWeaver" to turn off data when on Wi-Fi which consists of 90% of my day as I'm Wi-Fi connected both at home and work.
- Of course always turn off that option within Wi-Fi settings to untick "Always Scan".
- Went into "Google" app settings and turned off about everything I can find in there and it's now rather complex settings.
- Turned off most syncing of my 2 "Google" accounts to only one having anything other than Email Sync active such as the Calendar, Contacts, and Apps Sync. - Again, my 1 Google Account I only have set to sync Email and nothing else.
Sure I forgot some things I've tried but again, I am open to any/all suggestions. I admit, I bought my T-Mobile via Swappa. All seemed well as per their checklist of the obvious things to check regarding the phone's operation. Kind of stuck here now and wondering if my device is simply defective and/or the battery.
Also of note: Android System is always by far the largest contributor to my battery drain and exceeds even Screen-On time by around 10%. But then again, don't really know if that means anything or not since even before switching carriers and the transition from "JellyBean" to "KitKat" on my previous S4, Android System became a forever battery hog for me.
Just never had a top end device such as this in past years barely get me through a complete day: Work & Home time. I don't consider myself a heavy user. Barely even "Moderate" many days as I mainly text during my lunch break, otherwise phone is pretty much idle. And say 2 phone calls of aprox 20 min.s each during commute time. Yea, something just isn't right. :crying:

I have noticed 3 things that were hurting battery bad.
1.) Use the Google play services with the 030 extension. I get way better battery life on it 5% to 10% increase in battery life. Link below:
http://www.apkmirror.com/apk/google...ices-7-0-99-1809214-030-android-apk-download/
2.) If you are not using maps or other location services turn your location off. Literally a 20%+ increase in battery from this alone.
3.) Toggle your NFC. Something in Android 4.4.4 sometimes causes your NFC to wake lock. If you turn it on then turn it off one time it normally fixes is.
I attached my battery stats below.
It with about 2 hours of screen on time.

Thanks for the reply and suggestions! I just checked and I am currently running Google Play Services V 7.0.97 (1791429-030).
A couple things I have done meanwhile since my OP which have had "some" noticeable positive effects on my battery duration, yet still no where near what you have posted are:
Within "Google Settings" app:
- Account History ( I have "turned off or rather paused" ALL the Activity/Info/History settings here - All 5)
Regarding my 2nd, basically "Junk mail" Gmail Account:
- Now have ALL "Sync" turned off within, including the syncing of email, which I now simply check manually to update.
Greenify:
- Revisited, and added a bunch more apps and pretty much "Greenified" ALL Samsung related entries/services/ect...
So far I have increased to achieving up to about 3 1/2 hrs Screen time (Gained 1 hr) & a few more hours of real time battery longevity as I can now achieve close to 20hrs before needing charge.
Still feel I have some troubleshooting to go. Oh, I actually have the NFC Service "Greenified" to. So far haven't really noticed a problem with "Deep Sleep" either according to CPU SPY pro.
Yep, Have always had the Location Service to OFF, not even using the so called "Battery saving" selection with it. Such a pity to have to cripple such things but it's a trade off I guess in achieving a full day's battery vs.s using the features with this phone for some reason more-so than past devices it seems. At least in my case. :silly:
