Battery use

Hey bros I need to save more battery what can I do?
Sent from my SGH-T959 using XDA App

u can perhaps install the CM7 ROM (gingerbread)
that has given me phenomenal battery life.
other that that, you can do a quick search in the forums to see what others have done.

I second that motion. CM7 is great, and can give you even better life then it usually does with a little tweaking.

if you dont want to install new ROM your best bet will be juice defender from market.

powermax donate version works best for me.
also some settings..
turn off background data, bluetooth, wi-fi, turn off gps and also use wireless networks to determine location; unless you absolutely need your location.
I also use SetCPU, set to conservative.
I also configured profile, screen off = ~400mhz max and min = lowest available.
check settings>applications>running services..stop anything uneeded and uninstall, change app settings as needed.
I also turn off all keyboards I wont be using anytime soon.
turn display down below halfway, turn off all haptic feedback/vibration & blinking lights, etc.
sounds like a lot to sacrifice, but after a week or so, I realized it is best to have battery and just toggle things as needed.
hope this helps. there are more tweaks just search your devices forums.
peace.

traveler's kernel/rom or app

I use my tf for navigation. i hook it to my car's audio too and it's so nice to be able to listen to my music and have it auto adjust the volume when the navigation app says directions.
but i only get 5 hours of battery life with the screen on dim and the gps on(plus music). of course i can get the battery to last 10+ hours if i turn the screen off during long stretches of road. But i'd like to see how much battery life we could squeeze out of the device by killing unnecessary processes, underclocking/undervolting(it seems fine at 500mhz), and maybe some kernel level adjustments could be made.
i'd gladly flash to a "light" kernel like this before going on a trip and then flash back once i arrive. it takes 5 minutes.
maybe some android dev will have interest in this. or maybe there's not much more we can do about the battery besides underclock/undervolt existing kernels. anyone know the answer?

I'm assuming you're already rooted with recovery. There's an interesting app in the app section called SwitchMe root profile manager. What it does is make separate installs of android on your tab. What you could do with this is make a 'superlite' installation, with almost no apps to run in the background in the first place (just GPS and music, basically) put your favorite Guevor kernel on it, and underclock/volt as far as you can without losing functionality. Maybe give this approach a shot, or invest in a nazi task manager with only your gps and music as favorites.

Not using phone/sms/data, maximize battery?

I stopped paying my bill back in June since my job provides a cell phone.
Now it is simply used for mp3s and ebooks.
I have a Nexus 7 but still a bit too large for my taste to pull out on the subway train in New York during rush hour.
Currently I use my old Galaxy 1 Vibrant as only an alarm clock and I only have to charge that every 3 weeks or so.
This phone, even if idling on my desk will lose 10-20% over night.
I have airplane mode on and data disabled. What else can I do to get this up higher?
Currently im on aokp milestone 6.
I guess a rom/stock would be an option now as I'm not really using it for anything else.
Any particular processes to freeze in Titanium?

Any apps that you don't use... remove them. They aren't helping anything just being there.
Install Greenify and greenify anything that you don't need to have running in the background, but that you actually use. I like to greenify Facebook and other apps where I don't want them to always be running, but other programs work better with them installed.
If you have the donation version of Greenify, it can tell you which apps are waking your phone out of deep sleep as well. That can help save a ton of battery life when you decide that you don't REALLY need that app if it will wake up your phone 900 times overnight.
Look at the various running applications and consider their usefulness. Do you actually want that program to be running in the background? Is it useful? Is it worth the battery? That's something only you can decide...

Definitely take a look at Better Battery Stats -- it will reveal the culprits pretty quickly.
Install a ROM and don't install gapps, if you can get away without Play (store). At the very least, freeze all the Google crap when you aren't using Play.

MAXIMIZE the Battery Life of your Note 3 (Fix to Battery Drain issue)

Firstly, I want to say that this thread is based on the Exynos Note 3, not because it will work only for that device, but because it is the device I own at the time of this OP. HOWEVER, I can assure you that the tips in the second part of this guide, tagged 'IMPORTANT TIPS', would go for just about ANY device running android as the effects are similar. Now... Read On!
Since the MJ7 update was released, some Note 3 users have been experiencing weird battery drain issues, the MK2 update was also released and it didn't seem to fix it either.
While some users say a factory reset did fix their battery drain issues, many still have it after doing the factory reset, Me being an example.
I think the main problem is that the phone doesn't go into deep sleep.
So, I took sometime to research a fix and couldn't find a really solid fix, so I decided to go for the Next Best Thing, tweaks/settings.
Tweaking the phone in such a way that you maximize your battery use is what I will write about in this thread.
After tweaking my phone, I was able to hit 9hrs 30mins screen time with a total time of just over 1 day (24hrs), WiFi on ALL through. Not much Voice call time however.
On Mobile data, the tweaks won't give you this much time but still expect about 5 to hrs screen time.
How did I achieve this? That's what I will share below. But before I do, I will like to say that I have the Exynos Note 3 and this might be somehow targetted to that device (mentioned this earlier). However, if you have a Snapdragon Note 3 or any other Android device for that matter, I'm sure one or two things from this post will be helpful to you.
I will also say that 'Root' is quite important for some of the tips. If you are not rooted, you can just apply the ones that don't need root.
And For Non-Root users, Freezing App in TB can also be done manually to some apps by going into Settings > General > Application manager > All. Then scroll to the app you want to disable say Maps which is a HUGE battery drainer as i will mention below, select it then click the button at the left top which says 'Disable', I think it says 'Turn Off' in KitKat.
1. Factory Reset: I think the first thing to do first is Factory reset your phone, just maybe! That might work for you. You can also skip this step as factory reset is alot of work and might not be worth the stress in the end. But, I think a fresh start is always good once in a while NOTE: Backup your Internal SD to your PC or another flash media device FIRST if you decide to factory reset!
THE MAIN PART
=======================================================================================================
2. Kernel: Download a good Custom Kernel that also has the 'ondemand' governor. For Exynos Users, I recommend goodHanrry-kernel v2.0A (Used in first test)
Get it from his thread here - http://forum.xda-developers.com/showthread.php?t=2569056
NOTE that this is still a JellyBean 4.3 ONLY kernel till date
OR
halaszk-UNIVERSAL5420 v0.6A (used in Second Test)
Get it from his thread here - http://forum.xda-developers.com/showthread.php?t=2590320
I recommend v0.6A for Jelly Bean and v0.14B for KitKat or the latest Test for urself
Snapdragon users should try the ones they have too.. I'm sure they have some good kernels,like Perseus kernel but again i have Exynos Note 3 so try it for yourself.
3. Kernel Governor: Download SetCPU (paid) from here - https://play.google.com/store/apps/details?id=com.mhuang.overclocking
Go into SetCPU and change the Governor at the bottom left of the page there to 'on demand', then tick the 'set on boot' option in the middle so it will be applied after everyboot.
What the Governor 'ondemand' does is the CPU ramps up only when you actually need it. Hence the name Which also means that 'even if' you don't get good deep sleep, your CPU will stay at the lowest frequency, Saving you battery!
============================================================================================================
IMPORTANT TIPS
============================================================================================================
4. Greenify: EVERY rooted user must have Greenify! It's a fantastic app! It hibernates apps that you are not using so they never get to use your battery, yet the apps are available whenever you need them. No stress!
Download Greenify here - https://play.google.com/store/apps/details?id=com.oasisfeng.greenify (I bought the paid version as it has more fuctions)
For those who don't know greenify or how to use it, it's simple! Only Greenify those apps you don't rely on for Push Notifications.
For example, don't greenify apps like WhatsApp, Facebook, Viber, Twitter, BBM if you expect to get notifications from them in the background.
Feel free to Greenify other apps like your games, adobe reader, dictionary, and the rest of them as you don't receive notifications from.
Starting from Greenify v2.0, even None Rooted users will be able to use Greenify Just without the option of Automatic hibernate, however.. It's still Great!
TIP: If you are a Non-Root Greenify user, I will highly recommend that you put the 'Hibernate Now' widget on ur homescreen so that you have one-touch hibernation. Just tap it before you lock ur screen or at anytime really. I'm a Rooted user and I made it a habit already! Tap then lock screen
Greenify is a FANTASTIC app!
5. Power Saving Mode: Use the Power Saving mode for as long as you can, I use Power Saving all the time. What this does is throttle ur CPU down to 1.4GHz (Exynos Note 3),
lower frequency naturally means more battery. The Note 3 is a pretty powerful device, so I even play games on Power Saving mode without issues. But if you feel you need that extra oomph!, then you can put it off before you play your games and turn back on later. For the more advanced users, you can make these more dynamic changes with apps like SetCPU or CPU Tuner.
6. Screen/Brightness: As we all know, normally the screen consumes the most power so if you can manage ur screen properly, u can get some extra juice. My advice on brightness is set to 'Auto -5'. However it is fine to use any other Value from -5 to 5 as you like it. Then you can set to a timeout range of 30s. Try to avoid using live wallpapers as it uses the GPU for the animations also AMOLED screens save more battery when you use dark wallpapers. Do that if you love dark wallpapers
7. GPS/Maps: Now, GPS is like the Number One drainer of battery and many many people don't know this. Here is what you do, pull down your notification bar, long press GPS there then make sure everything under GPS is turned off always! Leave turned off unless you need to use GPS.
Maps is also another app that drains battery in the background, I don't use maps at all, so I keep it frozen all the time using Titanium Backup.
But if you use maps, my advice is that you open up TitaniumBackup, look for maps on the list of apps, long press it and then convert to User app. Now u can Greenify it and it will still be available whenever you need it.
8. Google Now / Google+: Google now does drain battery, if you don't use Google Now, turn it off. Go into Google now, enter settings and turn off. I keep my Google now frozen as I never use it anyways. If I ever need to, I will unfreeze it. If you successfully handle numbers 7 and 8, you will not have issues with Google Services drain anymore! Unless you go traveling alot
Google+ is one app that drains alot of battery, if you do not use it much or don't need it at all, my advice is that you handle it. Greenify it or better still, Get rid of it.
9. Sounds/Vibration: Maybe not really a big deal, but those keypad/touch sounds do drain battery. It's fine to leave them on if you like em, but if you can do without, then do! Especially Haptic Feedback! Settings > Device > Sound. You will get the option there to turn them off. Including keyboard sounds and vibration
10. De-bloat: Samsung always loads alot of bloatware on their phones, the more the bloat, the more the apps running in the backgroud, the more the RAM consumed and in turn, the more the battery used! If you can, go into Titanium Backup and freeze as many bloatware as you are familiar with, don't touch anything you don't know. Lol. I always debloat any ROM I flash, so i'm quite familiar with the process. Anyways, just a heads up! If you freeze 'Magazines' for some reason your Stock Email app will crash whenever you try to open a new email or clear emails from the notification bar. Gmail app will work good, i decided to mention as my main email address is Yahoomail.
11. Reception: Believe it or not, reception is VERY IMPORTANT when it comes to battery life saving. If you have good reception, then it's smooth sailing and good battery, but if your reception isn't good then your phone is always always trying to reconnect your apps and services to the internet, over and over and over again! Trust me, this can take a serious Toll on your battery. If you notice my screenshots below, I have near 'PERFECT' reception. Notice the green Network mobile signal area in Graph. No blemish!
Here is how: Well, since i'm always on WiFi (have a pocket router).. I never need the '3G/HSPA' reception, so I set my phone to GSM/2G Only (Settings > More Networks > Mobile Networks then change Network mode to GSM Only). I'm using Exynos Note 3, so I don't have LTE, but if you are Snapdragon user with LTE, You can set to either just 3G Only as that should still be more stable than 4G/LTE, you can still set as above too, afterall you won't be needing the LTE connection when on WiFi.
All I said right now about Reception was complicated yes?
This App makes it simple - http://forum.xda-developers.com/nexus-4/themes-apps/app-intelli3g-2g-3g-4g-toggle-battery-t2580234
Haha!
Finally, I use Nova launcher now as I have frozen Touchwiz launcher. Nova launcher is fast, plus i LOVE me them Stock KitKat icons And I feel Touchwiz Launcher on MJ7 and MK2 does drain battery much.
(DO NOT FREEZE TOUCHWIZ LAUNCHER IF YOU DON'T HAVE A 3RD PARTY LAUNCHER INSTALLED! YOU WERE WARNED!) You will get Force Close unending
Having written all these, I know some of you will want to come on here and crucify me, because you disagree with one thing or another. But the thing is... I'm only trying to help, and this works for me! I only 'HOPE' it will help as many people as possible enjoy their phone even more
Here are screenshots of my Battery Stats, maybe they will convince you to try one or two things out You will notice that BBM still drains a chunk of my battery, but I can't do without BBM And Nova drains less than TW was.
CHEERS GUYS!

Pretty good post OP. I have already given some of these a shot. I'm unrooted. Rooted my note 2. Still unsure about the 3 as there isn't as much information on it.

I also think having perfect signal the entire time plays a large effect as well.

Yes! Bad signal can actually drain more battery. As applications dat need internet keep trying to reconnect.

I averaged 9hrs 32mins screentime with stock phone Not rooted and no special apps. Wifi the entire time with a Sprint note 3. Its all about your signal. The better quality signal the better battery life you will get. You can flash the latest and greatest roms and kernels but if you have a poor signal you will have poor battery life.

Actually, battery life depends on sooooo many things, signal, ROM, kernel (in some cases), apps installed, apps running in background, GPS use, screen settings, even down to little details like wallpaper funny enough lol. I believe I can think of a lot of stuff, however! Very true! Poor signal will also drain battery, out of experience I speak.
Afterall, My battery has sat at 100% for 9 whole hours on Airplane mode!

Yes you are right Google now drains a lot..!! I thought it was only me he he.. Even in airplane mode it drains .. Unbelievable.. Last night I just put it on vibrate and it didn't drain anything... last three days it drained 3% in 5 hrs in airplane.
Thanks for your advices man..:thumbup:

Battery is not bad, ROM bases are not too good. Mobile data drains A WHOLE lot than WiFi.

Snapdragon
Root
no tweaks / no kernel change
But only 3 hours screen on time
you can also buy yourself a Samsung Note 3 extra battery kit
you can charge that battery in the kit itself.. you'll have 2 batteries with 100%
it only costs 30euro / 41 dollar

Nice little post there!
Some obvious, but some pretty good tips. :good:

It seems 'Google Play Services' owns your device and not you! Disable GPS, Google Now and Maps if you don't use it and see that you will get ALOT better battery life

@stanley08 , I never did a factory reset on a droid b4, so how do I do it, what will I lose & how do I backup, though my concern with backup is I might reload some battery hogging data or settings which would result in waste of time & screwing around with a already set up phone.

This is the Wise thing to do. Do whatever backup you want to do, Titanium Backup, SMS backup, Call logs backup, Nandroid Backup, and any other backup you want to do. Then Create 2 folders on your PC. Name the first one Internal Sd and the Second one External SD.
Then connect phone to pc and open up ur internal sd, highlight all and copy to the folder on ur pc names Internal. Do the same for external sd, but this time... Copy your external sd contents to the other folder you named external sd. That is IF you have/use an external sd. For me, it is pretty convenient to backup my external sd as it is a 16GB one and only about half full at all times.
NOTE: Wipe data/Factory reset in Custom Recovery like CWM will NOT delete your files on the internal sd of your phone. It will only remove your installed apps and reset ur settings...
But wiping from STOCK SAMSUNG recovery will do the above and ALSO wipe your internal sd clean. And that is what is called hard format. Or hard reset or factory reset.
I advice that copying data to your pc should be the LAST thing you do before wiping anything. This way, you will be certain that everything you backed up is safe as they are either on ur Internal sd or external sd. CHEERS!

After reading all battery issues I have refrained from updating my phone. I am still on M900XXUBMI5 should I not update if the update has so much issues?

(8hours) Maximum Battery with NoteIII(Exynos) with Dr.Ketan,Pekaka Kernel and SetCPU.

This is the complete guide for the maximum battery even with power usages.
First of all i am really sorry for my bad English
ROM
Dr. Ketan ROM l21 http://forum.xda-developers.com/showthread.php?t=2519897
Applications
TW Launcher frozen with titanium backup both TW Home and TW easy mode.
Using Nova Laucher as my primary laucher.''
Usning SnapLock instead of Built in Lockscreen. (set Built in Locksreen to none from the setting).
Uninstall the useless or bloatware apps like group play, google now, g+ samsung store etc.
Greenify
Added all apps to greenify except WhatsApp, viber and Sayhi.
Setting
All air and motion functions are off.
Power saving mode on for 24 hr.
Brightness auto -5
Kernel
This is the important and main part to save more battery recently i found Pekaka kernel for my Note III. Their are many comments about drain and getting device too HOT.
So i decided to play with kernel setting. And install setcpu setting thats work for me like a charms.
So after flashing the kernel do worry about getting device too HOT even with Playing Heavy Games also i have attached the setting for the SetCpu... Match your setting below and let me know if this setting also work for you.
The first three setting are to cool down the device if the device gets to hot, it will automatically scale the processor down to allow it to cool.
The other four are to save battery while the screen is off. This will lock the CPU between these lower frequencies when the screen is off, using less mv, resulting in less battery usage.
Thanks to Dr.Ketan for such a wonderful ROM
Thanks to Pekaka for the Great Kernel for Lollipop
Thabks to the developer of SetCPU app.
Give it try and let me know by your comments if this setting work with you or not.

I can see it now. According to ur ss, usage all over wifi or 3G?

@satslu Usage over WiFi.
WiFi remain always ON in my device I'm mostly indoor user so never OFF the WiFi even not in Use.

Here. Is New Results according to which you can use Almost 8hours with screen On.
Because this result are estimated from 92% battery not from 100%.

Your screen on time is quite impressive. I was on L21 up until the last few weeks. It was much better than stock TW, but still not what I wanted. I was thinking about switching kernels, but ended up on cm12.1 and couldn't be happier. djmax81 is finishing up a kernel for it that should improve battery, and it is incredibly smooth, even compared to Dr. Ketan's rom.

@mwbuss8 can you post the screens with djmax8 kernel ?"
