[Q] How to optimize battery life od Note 3 ? - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi !
I'am interested in optimizing battery usage/life on my Note 3.
I want to know what functions is free to switch off or reconfigure to decrese battery usage
But I dont want to cut phone functonality too much...
I'am not interested to tips like:
- switch Wi-Fi OFF
- switch Bluetooth OFF
- switch GPS OFF
- disable synchronization
- disable background data
- disable S Beam, NFC, Air Gesture, Air View, Smart Stay
- disable vibrations
- switch phone OFF when not using
- turn Power Save mode ON
- turn Airplane Mode ON
- lower down CPU/GPU frequency
Because they make phone much less usable and fun because it's many nice and amazing functions wont work...
I've already applied following tips:
- disable Google Now
- disable raporting GPS position
- disable location history
- turn screen brightness to AUTO
- remove unused/unneccecary widgets (especially this with auto update/sync)
- turn off autostart of unnececary apps (with All-In-One Toolbox)
- turn off "notifications from server" in "Samsung Apps" settings
Because i know that following tips are working and have positive impact on battery life (about 20% more power in my case)
I can't root phone (MJ7 firmware...) so I cant use Greenify to make more battery life...
If somone know some more configs/tips/apps that can be applied to increase battery life I will be very interested

- turn screen brightness to AUTO

This I believe is a myth, if anything AUTO uses more battery IMO. I set my brightness at around 40% or so and I get 30 hours (with 3-4Hours screen time) or so average out of my battery, Only other thing I disable is GPS.
It's more about how/what you actually use on your phone rather than what you can disable and not use.

I think you're looking for a reduction in "idle" battery drain as in use battery drain is kinda unavoidable.
There are tools like "Tasker" you can use to automate all the radios
you can use "app ops" to stop all the apps that push your location (this will do the most)
"autostart manager" allows you to stop apps from running all the time.

Do you have an n9005? If so the Snapdragon Battery Guru app definitely helps by switching your networks on and off based on usage, etc.

I never thought about that, I had that on my HTC One. But I didn't find that it helped much in all honesty. I'd be interested to know how well it's responding with the N9005 though, are you using it?

Yes I am. It doesn't make a night and day difference but it definitely makes a difference. I even uninstalled it to double check that I wasn't imagining it, now I'm annoyed with myself because it's still learning again.

Without all you wrote.. rules are those:
1) NEVER close apps (if you close the app ram pages will be deleted, so, it's needed to re-upload those, it has an huge energy consuption
2) use the phone "slowly".. i'm meaning, the fingers moves
3) if you are reading a text, read all the page than slide to see the new text, it's to prevent an high ramp up of frequency for long time

radicalisto -> thx for tip
nakedtime -> App Ops is quite good app ! Thx But "AutoStart Manager" is not working on my phone (crashing)...
dr.m0x -> I need to test this app thx

It's npt a good way to install an app to controll emergy consuption..
App needs cpu usage.. cpu ramp up..
so, you disable the radios for little time, and energy spent to do it could me more by cpu ramp up frequency
i suppouse you have the snap version.. and.. as i can see, snap has a good ondemand sysfs setting, it means it doesen't grow up frequency too fast, so, more than this is quite impossible
Only with an huge undervolt

I've installed this "Snapdragon Battery Guru"... now it's in "learning mode" I will see if it will help or not...
I have better replacement for "AutoStart Manager" and it's called "All-In-One Toolbox" which have the option to chose apps for autostart (and has many more other features) - i'am using it for quite a while and it's working fine

Snapdragon battery guru raplace the sysfs of the governor

First impressions from this Battery Guru are not so good... Battery is running down faster than without it... Maybe because its still in "learning mode"...

Yup just cause it's in learning mode, it'll settle once it's learnt everything

I will wait until "learning mode" ends and see if it's working

I am not a heavy user so a battery last more than a day sometimes 3 days.If I was I would just get an extra battery and not obsess over trying to maximise battery life.One of the advantages the Note has over most other phones is a removable battery.Take advantage of this feature.It takes less than minute to change a battery.

Replacing battery requires switch off the phone and taking off back cover of the phone (i'am affraid that it will damage it after many opens... i'ts a plastic after all...) and then put back cover and switch on the phone... It's troublesome and not comfortable...

It doesn't take long to switch the phone off.Mine takes 10 seconds.Taking the back off and replacing the battery takes another 15 seconds.Turning it back on takes another 15 seconds.All up less than a minute.
I can imagine how some people might be reluctant to take the back cover off almost daily.The back cover feels a bit flimsy and it's reasonable to assume it won't be durable with that sort of usage.I have the Note 1 and after two years of almost daily taking the back cover off it is still fine.The Note 1's battery life is horrible and even with light use I don't get a full day from it.Most people replace their phone after 2 or 3 years anyway so I don't think durability is a problem unless maybe you plan to keep it for 5 years.
But I can understand why some people might be reluctant to repeatedly tear the back cover off their brand new pride and joy.

I guessed everyone had their own way of energy conservation. For me, I use dark wallpaper. For our screen (Super Amoled), Black = LED off. LED off = not using energy. So in theory, black wallpaper or black background should uses much less energy than bright sunny light wallpaper.

This is very true for Amoled displays.The only time I notice my N3 drains the battery more than usual is when the display shows a lot of white such as internet surfing and using WhatsApp.Watching a movie does not display a lot of white and the N3 battery life becomes remarkable.

Battery
Go into the application settings and deactivate all samsung apps u dont need! Saves alot of Battery. Don't charge ur note if its Not empty. Just charge it if u are under 25%. You can also work with Tasker - it helps you to save your Power if u change yours settings automaticly. Also dont change ur brightness all the time
Hope it helps

What am I doing wrong here?

Ok I got the X10 a few days ago.. loving it.. now..
How do I extend the life of the battery? I know theres a ton of topics on this but I can't seem to get more than 12hours..
- I use StartupAuditor and pretty much stopped most apps from running at start.
- I use ADW Launcher
- I use JuiceDefender
- Timeout - Screen timeout after 15s, lock after 2mins
- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)
- Screen - Leave APN/Wifi enabled while screen unlocked (So it disables it after it has been locked)
Any help is appreciated.
After a couple of weeks your battery life should get better with out you having to do anything. Just be patient and let it fully discharge before recharging. Also restart your phone after a full charge and after using wifi and gps.

Discharing a battery is bad isnt it?
Well your problem may lay here
"- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)"
Your using Moxier which other X10 users have identified as a huge power user and according to you, your also using APN/Wifi for a minute every 15 seconds..........so it's essentially never turning the APN/Wifi off :-S
Hope this helps!
Also fully discharging your battery every now and then is actually beneficial for your battery.
Quite certain the 1 minute every 15 seconds is a typo
Juicedefender defaults to 1 minute ever 15 minutes.
I removed ATK and Juicedefender, I found they only screwed up things in the phone and after removing them I noticed no change in battery life. (If anything, my battery life increased after removing ATK)
The best things for battery I have found to be.
-- Alternate launcher (I use ADW, I think Helix is better for battery performance but ADW has more options).
-- First 5 charges, discharge battery completely and do this again once every month or so
-- After full charge, power cycle phone (Turn off/on)
-- Use quick settings to turn off GPS, WiFi and Bluetooth when you are not using them
-- Make sure you back out of programs when you're done with them. This will close most applications so they are not running in the background. Certain apps (like a dolphin browser) have exit functions under more options. This is useful as back will just go to the previous page.
Note: Force closing applications which you see open in the background may use more battery as it may just start up again. Constantly killing and opening the program will use processor/battery power. Whereas many programs, when open in the background, are not using active process power and Android OS will pause/stop applications which are not in active use, by default.

Screen brightness turned down. Wifi instead of 3g. That's what I do. And I think I get around 15 hours. Still kinda bad. But better than nothing.

From my experience..
I find 3G has better battery life than WiFi, unless you are constantly browsing. When 3G is active, but you're not browsing the web and stuff, I find it doesn't use much battery. WiFi, however, uses up loads of battery when the phone is idle.

Battery barely gets drained by wifi in idle state. you just go into wireless settings and set wifi sleep policy to when screen turns off.. should be fine after!!

As per my last question, discharging is bad isn't it? With these batteries, you have to constantly charge them so they don't loose life
Edit: Also.. if I press home button or back button that doesn't close the app.. most apps don't close like that, so I have to use ATK to kill it.. is it fine to leave apps running in the bg like that?
Edit: So I should uninstall ATK?
I also JUST got an X10 about 2 weeks ago! My battery life was so bad at first, and I ended up trying most of these battery saving apps. But to be honest, I found that they did more damage than good.
I now have everything I don't use turned off. Bluetooth, WiFi (when I'm not home at least) etc. Just skim through settings and turn off anything you don't think you'll use. And I restart my phone every morning and I get 30-50 hours out of it, depending on use. It is definitely getting better with time too.
For ATK, I would uninstall it as generally killing tasks does more harm than good. If you use it intermittently and only when necessary (and not use auto-killer) you could keep it installed.
As for apps running in the background..
-- If you press back, it should close most apps (not all, but well designed apps should)
--The Android OS is designed to pause/stop apps/processes which are not being actively used by the user and will close them eventually if left unused
-- ATK is generally only freeing RAM which is not important. It is not like Windows in the sense that more free RAM = faster speeds. It is a lot more like, more free ram = more wasted ram.
Here is a link to where I found out most of this information.
http:/geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
As for WiFi sleep policy, thanks for pointing this out. It seems that my phone is already set to sleep WiFi when the screen is turned off. I find this weird as I have found significantly reduced battery life when I turn WiFi on, even when my phone is mostly unused/idle.

i have noticed some thing strange ,the phone lasts more with apps open in backgroung than when i close them . and using my phone consumes less battery than leaving it in standby .very strange phone (may be only mine ) any confirmation.
Hey Hoss,
I can confirm that force-closing/killing apps seems to be worse for battery life than leaving them alone. Backing out of apps usually will stop any cpu usage, but leave the app running. Killing/closing them will just result in more cpu power to run it when necessary.
As for standby vs usage - I have the opposite experience. The battery life on my x10 lasts a lot longer when I am working all day and not using my phone very much.

[Q] Help, what is your battery drain, and why mine is sooo High???

First - let me state - and it is true - that I used the search function.
I read pages and pages of advices to lower battery consumption on my HD2 Android... without success...
First I used an SD ROM. I read that a NAND would improve battery life. So this is what I did.
I am also using SetCPU with a profile when battery <30% and another one when screen is off to LOWER the CPU speed. In normal use, I set CPU speed at 768MHz trying to lower power consumption...
I use a task killer to free memory and prevent silly programs to drain my battery off...
I use Juice Defender to control wifi, data, etc...
And with all of this in place, my "Current widget" shows a consumption of 180mA with screen on doing nothing, up to 350-400-500!!! mA when acutally using the phone wifi+sync...
In the forum I read consumption like 3 mA - 9 mA!!! This is FAAAAAR Way lower than what I ever had with different builds...
So this is an help scream to everybody: what is your battery drain, and why mine is sooo High???
Hint: I am also a fan of LCD Density changer, with setting at 165... can this have an influence on battery drain??? I reverted to the original 240, doesn't seem to have any influence...
Thanks for your help,
Looki
My drain is 3-9 ma in STANDBY ONLY now and again slightly more but mainly the values stated. And my screen on between 120+160ma. Turn off auto brightness if you have it on, and set it at the lowest your comfortable with (display is big batt drainer) I DONT use taskillers as they do more harm than good. I use NO undervolting and only the default settings with my rom. I have low lcd density setting 167 i think. Lcd density has no effect on your battery drain!
Found this here. http://forum.xda-developers.com/showpost.php?p=13151738&postcount=11296 Might be of some use to you? (from hyperdroid gbx thread)
Whats youre rom?
And do u use ext partition on sd?
I dont even use SetCpu anymore. Only taskkiller.
Auto-brightness is on
Auto sync is off.
Im using UD 3.3 nand from crawlingcity
Stansby is 3 -6 ma
Using round 160 to 250.

How long does your battery last from 100% to self shut down? As for Current Widget, keep in mind that when people say "Standby", its generally referring to the screen being off. Set current widget to update every 30 seconds, and turn the screen of for 40 seconds. Then quickly turn the screen on, unlock, and check what it is reading then.
If its still high, try "Force Stop" applications in the Settings > Applications menu one by one, i've had to do this more than once to locate problem apps that were destroying my battery in standby mode.
I'm knew to Android, let me share you my idea.
I use UD3.3
I removed google stuff
gmail, search, etc
No auto sync
Location off
Always kill market when screen off.
I use beautiful widget for weather manual refresh.
I use battery widget
Auto level for screen
sometimes WIFI on
2g Only
2 or 3 calls,total of 3 to 4 min a day
My battery stay 48 hrs in STBY mode.
I think the most draining factor is
1) google stuff they are battery hog.
2) screen
3) bad written programs (every time they check connection to
internet or looping for doing something, looping will make
CPU in high frequency).
4) bad device driver such as BT which is known as 60ma
drain. it is not the hardware but it is the software doing
the drain.
thanks

[hint] battery saving tips

Disclaimer; This does not damage your phone at all or fry/mess your cpu.
This method is used to lower CPU stress and increase Battery life
This method works for all rooted phones.
IMPORTANT: The newer versions of SetCPU might prevent your phone from entering deep sleep. Download version 2.24 from the following link which is the one with no problems and completely works 100%.
LINK
Deep Sleep breaks when charger is plugged in, you can see this by CPU SPY application available on playstore
Stop Downloading Battery Saving Applications, they do nothing and uses RAM.:silly:
Also Turn BLN off when you are sleeping.(It also Consumes battery and sometimes prevent deep sleep of CPU)
Set your Brightness to minimum and disable auto brightness.
LINK to Display Brightness
Instead use lite app called - Display Brightness from play store.
Turn off wifi and mobile data when not in use.
Use toggle for auto rotation, and keep off when not needed.
For more battery Saving, disable all animations and set screen timeout to 1min.
The S plus sucks in battery life. We all know that.But here's a fix, Try Under clocking instead of Over clocking.
When screen is on:
MAX 1.4Ghz(Why to OC??, if your phone runs smoothly on 1.4Ghz)
MIN 192Mhz
Ondemand governor (This governor jumps up to max when needed but spends most time on the min freq. Best battery saver.)
When screen is off:
MAX 365 Mhz
MIN 192 MHz
(This prevents lagging when playing music and other activities when screen off)
This way, you have a beast quick phone when you're using it, and the best battery saver when you're not!
NOTE: Turn off Autosync from the settings. It's only used to sync your gmail and contacts and such. You can manually sync when you add a new contact and since I don't use gmail, I refresh manually whenever I do.
SetCPU:LINK
Specific instructions for those that can't get it to work!:
On SetCPU:
Click Add profile
Where it says Profile, select it and tap "Screen Off"
Set the frequencies you want in use while screen is off (If you want just one frecuency, put both sliders on the same number)
Set priority (in case you have other profiles, otherwise don't bother)
Select governor (Won't really matter since cpu is gonna be running at 1 frecuency)
Tap save
Go back to Profiles tab at the top, then tap Enable at the top left to make the profiles work.
For a list of most governors and I/O schedulers detailed;
Visit
1.LINK
2.LINK
To check if its all working, install CPU spy from the playstore: LINK
For Playing GAMES(HD)/HEAVY GAMES, Plug your Charger in and play if possible.:good:
Most Important thing is to calibrate battery,
Calibration of battery is needed when you change your ROM.
This process wipes batterystats.
Battery Calibration
1. Charge 100%(NON STOP)
2. Download any battery Calibration tool from play store; (Link to App)
3. Open that app, click battery calibrate
6. Unplug your charger
7. Discharge your phone down to 0% during the day
8. Charge back up to 100% (NON STOP)
This is to make sure you're using your battery at 100%. Only do this after you flash a new rom.
The worst battery killer is 3G. No matter how much you try to optimize battery by tweaking and underclock, if you have 3G on, you're gonna have a bad battery drain.
Make sure that Autosync is disabled.
Done A small test usage 14 mins , you can see in attachment your CPU should look like this.

Don't get apps that take background processes like what xellar said, facebook, and some other apps like tap tap revenge 4. Anyways thanks for the tips and link to free setcpu
Other people can also share VALID ideas about saving battery.
Will help many users.
Nice advises. I'm already using these.
One more good thing is turning mobile data off whenever you are not using it, also bluetooth, lowering brightness.
Good app for doing so is Power Toggles. You can always have widget on home screen and switch on/of these things with one tap.
Riiight.. Turn off autosync, disable 3G and wi-fi, dont use apps or games.. I might as well buy Nokia 3310..my phone lasts easily whole day with wifi on..with 3G it can get me at least 6-9h which is fine.. The key is to turn off 3G when you are on wifi and turn down brightness.. Everything else is not using your smartphone smart..
1) Set your network mode to 2G only if you're not using 3G/WCDMA
2) Manually set your operator in settings.
PS: After flashing one of firmwares I got a bug - battery is not charging to 100% while phone is ON. Only to 99% and not showing a message about fully charged battery... But when the phone is in off mode - it charges to 100%. Anyone knows how to fix this thing?

On Amoled-Displays it should help. Inverted Apps, too.

i testet the new version of setCPU 3.0.9, deep sleep works perfectly.
If profiles are not used it exits and there is no use of RAM in both versions (But then you do not have the unique feature of auto switching profiles ).
Is there another app with auto-switching?

But it has no profile-autoswitching, in fact no profiles at all. Voltage control Extreme has at least profiles, but without autoswitching. What is good about Voltage Control Lite/Extreme is that it sets cpu setting with init.d and so the app does not have to start on boot
Yes that is nice...

Many thanks for the battery saving hints. I'll finally kick out the Task Killer App, doesn't really seem to do anything except creating problems ..
For the statement that Underclocking would help in saving battery I wouldn't fully agree. A slow cpu needs more time to complete a task before returning to a sleep state. Of course the battery drain is higher with a higher frequency (which also require higher voltages), but I believe, that there isn't much to gain on this front. As long as I don't see any profound evidence I'd even suspect, that an underlocked CPU overall could even cause more power consumption. You can also read more opinions about this in general in this thread.
Much more beneficial would be to identify those apps that cause frequent wakelocks. Does anybody have hints here, how to track down those 'bastards' ? (From my Linux I know 'powertop', does something similar exist for Android? (Or are the battery statistics in CM10 sufficient to decide which app to wipe?)

[Q] Unrooted Note 3 - Battery Drain, Most Tips didn't work.

Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.

How to Increase Battery Life - Tips

Some will say the battery is good others will say it sucks. I have hear them both for the Galaxy S6 so here is a few tips for increasing the battery life on your device. This works for any Android device.
1- Avoid Live wallpapers, instead set Dark wallpapers.
2- Set Brightness to " Auto " and lower Timeout Duration
3- Delete unused widgets
4- Toggle From 4G to 2G
5- Changing Application Sync Settings
6- Disabling Background Data
7- Close applications that you are not using
8- Turn off WiFi & Bluetooth when not needed
9- Disable unnecessary features & gestures
10- Enable power saver (Duh)
Here is a video guide on how to access and use these features on your phone if you dont happen to know how to.
​
So what you're saying is, buy another phone.

Apparently if you switch the phone off the battery will last for months.

I'd just like to add, if you keep it plugged into the wall charger, you can achieve over 20 hours SOT!
In other words, turn off all smart features of Smartphone and use it like a 3310
Add this to your tips:
Switch it on only when you need to use it, or expecting a call.
Also you can use ultra power saving mode all the time.
Yeah, I am amused by all the battery life obsession these days. Folks strap on suitcases to their phones in the name of extended batteries. Reminds me of the old motorola star tac days.
I am one of those people that is getting outstanding battery life. At the end of a typical workday with frequent testing and browsing while on the bus etc., I have about 40-45% left when I get home. That's only marginally off the Note 4 I had which would be around 55% at the end of the day. Only things I have done are disable stock amazon app, disable wifi scanning, disable wifi calling and set screen brightness to auto. My BT is always on, as is VoLTE.

No, to me the battery is good enough. Yes you can use ultra battery saving, but I'm not saying to use all of these at once. Using a darker wallpaper will help with battery. Thats something I do and not the rest. If I needed more battery and cant get to a power source then I do a few other things that don't require me to turn my phone into a dummy. These are just a few tricks cause some where getting a bad battery life compared to others.
Lol there's no way I'm using dark wallpapers with this amazing screen.
A true black wallpaper is my favorite battery saver. Maybe it's just me but I love seeing the deep black super amoled allows us to have.

Thread Gone Off Topic significantly. Closed. There are plenty good (and better )Battery Saver Guides around here for those who want/need one.
