Well I've been using Juice Defender for half a year on two different phones. How much battery it can save you is debatable. So long as you don't have excessive SNS polling and partial wake data usage problems of some sort, it's not going to net you much of anything.
I was an ardent user of this app, but the last week running without it at all (running Bionix Final JI2 modem) compared to the first couple of days running this firmware I can say with confidence it's not needed for me any longer. I'd even go so far as to say I've been a victim of ye olde placebo effect.
If you don't have the pro version the automatic defaults are about as good as it gets. Best of luck.

Personally I had worse battery life with JD, I would stay away from it.

Get Tasker instead. It can do anything JD does and WAY more. JD worked for me, but it caused the stock ROM to run a but sluggish.
Sent from my SGH-T959 using XDA App

The main thing the JD does it seems, at least by default settings, are two things. First, by default it disables your APN connection (3G/2G) when battery falls below 15%. I've disabled this, I keep an eye on my battery anyway. The other thing by default is by far the better of the two. By default, it turns on your APN connection for 1 minute once every 15 minutes for a duration of 1 minute. By default, that's all this app really does, and it doesn't need to ping the CPU as it sits between 0.0% and 0.1% CPU utilization as reported by Watchdog.
I'm not advocating the use of this app nor am I claiming this will even save battery life, but given the knowledge of what its default settings do, I'm of the belief that having your APN turned off for a substantial part of the day will increase battery life between charges.

For completely non-technical users, JD is the way to go. However, with just a teeny more effort you can do WAY more than JD is capable of doing. Stock firmware with JD I could get up to about 14 hours of battery life. This is doing a bunch of texts, reading gmail, and getting Exchange mail via touchdown. With Bionix Fusion, J12 modem, not using JD, and keeping the phone in 2G and not 3G I can get significant battery life as the image below shows.
At the time this shot was taken, I was down to 15% battery and 4 hours according to Juice Plotter.

I been using with the Bionix 'core' kernal and it's giving me decent battery as opposed to no defender where battery life was not good at all. seems to work as advertised, i charged my phone 4 hours ago and it's at 100% (but didn't use for any calls yet) . Otherwise it would be at 92% or so without JD. Mileage will vary

Well, I think people are ascribing too much mysticism into what JD is really doing. With its default installation left intact, it simply shuts your 3G (APN) radio off when the phone becomes relocked (screen off), just as your wifi connection shuts down when the screen turns off. While the phone is locked, JD turns the 3G radio back on for a minute once every 15 minutes. That's it. There's really no magic. So, if you think having your 3G radio turned off automatically every time you shut the screen off sounds like it might save your battery, then it probably will.

i saw in the tasker wiki there are two profiles... from those two profiles, it seems like to "recode" jd with tasker might be a hard task for a tasker newbie like me...
any suggestions or hints to enhance the wiki profiles?

I use JD and not noticed alot and an app that should be used is superdim to dim your screen backlight even more than settings let you and also found i had few apps that are using more power than my screen so its all about apps installed and way there all configured so Milage may vary by hours between phones so unless your phone is set up exact same way as another device thats the same dont expect all to be 1 day battery + is battery life really all that confusing

That's not how I want to keep a long charge. What about email, and internet based apps/games? Juice defender works ok but it took too long to auto enable/disable data.
Theres an app called DC Switch that I used with Android 2.1, that does the exact same thing as the "Data Network Mode" toggle in 2.2. It even has a widget you can use to toggle.
Nothing new.

Yup, if you turn off data then your battery last a real long time. It lasts even longer if you put it in airplane mode.

I agree. Whats the point of having the phone at all if your miracle to saving battery is essentially removing all of the features that make it a "smart phone". Its like saying "I get unlimited battery by simply plugging it into the wall and keeping it on wi-fi. Just dont go anywhere or doing anything. Its great! I did already beat Dungeon Defenders three times.... I wonder what the outside world looks like? Oh wait there is an App for that!"

The point of a smartphone is to have the "option" to have all the stuff on all the time. A smartphone gives you a choice. That's what makes it smart.

"when you aren't using data services"
There is the issue right there. Many of us rely on our apps to automatically use said data services - such as email, weather, twitter, etc. pretty much all the things that people tend to buy a smart phone for - and turning it off defeats the purpose of having such a device.

[Q] Disappointing Battery Life

I got a Nexus 4 yesterday, and so far it has been excellent. Really fast and has all the features I want. The battery life is pretty poor though. I am at 28% with a screen on time of only about 2 hours. The total time is about 8 hours. I haven't been using it a lot. The main thing consuming battery seems to be Nova Launcher for some reason. I have it on my Nexus 7 and it doesn't decrease battery life at all, but it seems to use a lot more on here. It was at 24% according to GSam Battery Monitor.
I just followed a bunch of instructions for increasing battery life from various websites so I will see how it goes. I now have all the Google syncing disabled, location services off and brightness on auto.
Is there anything I should be doing? Why is Nova Launcher's usage so high?
Thanks,
EDIT: Could it be the widgets I am using? I have two Gmail inbox widgets, the messaging widget and the circle battery widget.

Same here though I'm not sure its nova, my battery got as bad as yours when i rooted to stock.

it could, or any other apps you have working in the background. it can also be how you use the device. but before you assume anything about your battery life, give it 3-4 battery cycles before it normalizes.

im ocd about that too, lol. the back button to kill is one of my favorite custom rom features. also, autostarts and greenify are both great apps to make sure that you have mich less ctap opening in the background. anyways, im a heavy user normally, battery life on the nexus 4 id never call bad. usually i get 3.5-5.5 hours screen on time, depending on use. but then again, i use a custom kernel thats optimized for performance and battery. but, stock rom/kernel isnt bad on battery.

I too Force Close all the social networking apps before sleeping and turn wifi off. And i daily get around 4 hrs of OST. Will attach pics later to show. So to get 4 hrs OST you need really need to have a custom kernel. Just optimize your usage and you are fine with the stock kernel.
Phone is totally stock. Not rooted. And i got 6 pages on Apps installed.
I even used to clear RAM every now and then but I just stopped doing it as I couldn't find it doing anything better.

The battery life is much better now. Yesterday when I got back from school it was at 40% or so, and today it was at 68%.

Gets better after a few battery cycles. My battery life was average, so I rooted and with matr1x kernel it's snappier and better battery.

i'm stock and my battery life was shockingly bad on the default settings until yesterday when i tried some fixes and they have made things much better.
looking at my N4 right now, i'm still on 58% after 22 hours. that's after several voice calls, some browsing & reading emails, GPS navigation using Maps, a couple of skype video calls, wake-up alarms etc.
basic fixes as follows:
- screen brightness right down to maybe 10-15%
- data off when not being used, ditto location services
- NFC and BT off.
- i've left wifi on as it doesn't seem to take much battery if it's not being used.
that's all! after charging last night, i woke after 6 hours or so and was amazed to see it had dropped only 1-2%, so apparently nothing is waking it from sleep.

One thing that really improved my battery life (when I had a Nexus 4) and something I tell to anybody with poor battery life, is to go into maps, go to settings, location settings, and uncheck "report from this device". If you've got the app "wakelock detector" just watch the wakelocks from maps almost entirely disappear. It nearly doubled my battery life at the time.

Hey thx man that didn't work but it did start me down the path to fix my problem.
I found out it had something to do with my GPS options its in settings and location access WiFi and GPS location options i checked it off and now i am getting 1 hour screen on time for every %10 if you do the math i have about 8hours of screen on time! I also have setcpu app which is giving me about 48hours of standby time, i will upload some screens after a bit more testing.

If you would like to risk such things as unlocking bootloader, rooting, installing custom ROM and kernel, then it'd be easier for you.
Personally, I've found codefireX ROM and faux123 kernel to be battery friendly and very responsive, but of course you've got to be a bit fixed on such things as playing with your devices and getting fun from it to do that

___ BATTERY LIFE THREAD ___ Being raped by Android OS!

Who is having issues with battery here? Android OS is killing my juice! I have gotten fed up and rooted my sheild and frozen most everything possible to try and get the OS down. I will lose like 30-40% overnight. I was thinking it was the shield or nvidia services tied into the android OS but that doesn't seem to be it. Blake_wavelock seems to have a lot of the activity and deep sleep isn't Happing as it should. I haven't tried WiFi off when screen is off and I'm going to use that tonight. I have all the location setting and Google setting inactive. I'm using optimized for battery.
Let me know what you think. I come from a posse of Samsung devices and get great battery life on them.(of course they are all rooted and ROM)

Have you checked under WiFi advanced settings for keeping WiFi off while screen off and WiFi optimization? (Sorry if these settings aren't there, looking at settings on my phone, as I don't have this tablet, but I am considering purchasing one).
Also, is your WiFi signal poor or strong? Because that plays a big role.

I have this happening with airplane mode on. Only seems to happen when I'm home though.

Those with bad battery life should check what apps they have installed and use wakelock to find out what's keeping your tab awake over night. I have had many android devices and unusual battery life like many of you report is virtually always due to a user installed app or combo of apps. I get 3 days use on one charge MINIMUM. This is with WiFi on 24/7, and I use it for homework for several hours a day and some light gaming thru console mode (maybe an hour a day). I use a custom power mode with 50% cpu clock, 2 cores and 30 fps. I never take it off this power mode cuz I never see any difference in performance. Il post pics from next cycle.

Yea I'm not seeing bad standby either, battery overall isn't great but OK. I get about 5 hours screen on but most of my usage is android games.

Twice now, I have gone from 70-80% to dead in just a few hours with the screen off. I have a few background apps with push notification (facebook, appy geek, mighty text) but they are all the same apps as on my oneplus one, and it only drains 1-2% per hour.

That's more like it, still not what I call good but for something that offers everything I guess it's OK. Still wish I had a way of reaching 10 h screen on.

Go very dim and freeze everything and im sure you could get close! I do use greenify. I like app opps but to lazy to set it up.

Twice now, I have gone from 70-80% to dead in just a few hours with the screen off. I have a few background apps with push notification (facebook, appy geek, mighty text) but they are all the same apps as on my oneplus one, and it only drains 1-2% per hour.

I have the tegra note 7 and this shield. I pretty much just got both about a month ago. I have figured out that the WiFi hardware is not as good as most phones. So it will cause a wavelock and drain the device (which is labeled under android OS). So make sure under settings<wifi<advanced you choose WiFi off when screen is off or only when plugged and not to search for WiFi networks if you don't need. I have also seen that if you root then you can use titanium backup or whatever you like to freeze all the apps that cause harm or excessive battery drain. Also, with root you can use app called wavelock detector to figure out what app is draining you down. I have just about everything frozen except for updates and a couple other services. Good luck report back on what's causing it if you can. Blakewavelock got me, lol.
Here is this cycle from yesterday (still going) What wavelock detector looks like
More of this cycle

I'm rooted. what can I do ?

GREATEST battery life on Android O beta

I just wanted to put this out there. I have O beta installed with latest update, no root, bootloader locked, DNS66 app for adblocking and always on vpn, greenify (whatever it can do without root and jumping through adb hoops), stock launcher and I have never ever ever had such a great standby battery life. In EX kernel managers battery monitor, I see < 1 % per hour screen off battery drain consistently where I have not been able to go below 2.2% with any, (I say any and I have tried all) rom+kernel combination on 7.1.x.
This is GREAT!! I have never been happier with any stock rom ever.
EDIT: I would like to add that I have LG Urbane watch connected with phone all the time so bluetooth is on all the time but I bluetooth scanning is disabled (in location improvement, wifi scanning is still on). Battery optimizations for android wear is disabled.

Is it possible you can take a screenshot of your battery stats from settings so some of us that like visuals can see? What is your screen on time like?

That's interesting, cause my battery life and performance have both dropped significantly for me on O compared to Nougat

It's worse on O, though pretty great for beta. I've got up to 5h of SOT.

Best ever is 7h on PN and Frank kernel.
Stock usually 5h so the O isn't too far off. Maybe very slightly for me. It can only improve from here I think.

7h is unheard of. were you on battery saver mode the entire time?

I can get over 6h on a fully stock pixel, locked bootloader and all. I would say the majority of my time is on wifi. O beta seems to work well but my understanding from a community post by Google, don't have the link anymore, is you need beta Google play services installed as well to get O's battery benefits. I can't say that it makes more of a difference for me in comparison to avoiding notorious apps which hinder performance. I had similar battery life on N.

fyi: https://www.reddit.com/r/GooglePixel/comments/6djbbf/for_those_on_o_beta_you_must_also_be_on_the_g/

My battery life on O was horrendous. We're talking night and day. I run stock with not more than 20 or so apps. Something is really really wrong with O. I've gone back and forth on the beta twice with the same results.

I use the beta ROM about one week and it is very very good , also battery very good

I'm getting really nice batterylife with 8.0, which is awesome. It is now more in line with my average battery life with other devices like the HTC 10 and such. This however is fine to me as long as it's not dying by 1-2PM for me haha

If you can, please gives us a little bit more about your setup meaning if you have root, kernel managers, aggressive doze app (greenify, naptime, etc), limiting background services etc

I am completely stock, just updated today. I turned off background operation using the battery manager built in to Android to limit apps like Instagram, Facebook, Snapchat, Reddit, Chrooma Keyboard, etc.
For my usage my phone wouldn't last very long. I would probably hit 50% with an hour of screen on time. Now I'm at an hour and 54 minutes with 54% left. I've been off the charger since around 11AM, and it's currently 4PM so I'm definitely gonna have to see where it goes from here. When I leave work the real concern is heat when playing music or podcasts over Bluetooth, for whatever reason my phone was getting really hot when I used Bluetooth so I'll see how that is when I leave work today.

Is DNS66 same as DNS Changer? Also, how did you get it to block ads?

No it is called dns66. Install the app and it will walk you through it.

"DNS66 app for adblocking and always on vpn"....slightly confused by this..did you mean that you get privacy features like other VPN providers? AFAIK as I know DNS66 is only a local VPN and does not provide security/privacy features
