Hi All
Once again thanks for watching my video and getting me tickets to MWC...but alas i have another issue. My Note has horrific battery life....practically about 8 hours.
I downloaded better battery stats and there are no major wakelocks going on...(just juice defender at 3.4% which i uninstalled anyway) ....any other ideas?
Any help would be appreciated, another Mobiler suggested i put a custom rom on...I'm just terrified of 'bricking' my phone lol
This is perfectly average battery life for stock rom with moderate to heavy usage but if on light usage you might have some issues. Here is my battery like with heavy use.
Don't pay attention to people claiming Days of battery life they are simply not using the phone.

Battery life is certainly better than that on my old HTC Desire HD. Far better.

Maybe you could post up your betterybatterystats results?
I was having the same problem. I have a lot of apps on my phone, and it was just draining while sleeping as far as I could see. My main issue was all the unwanted apps like the social and media hub popping up whenever they felt like chomping on my battery.
I finally gave in and rooted, and installed droidwall to prevent anything getting network access I do not allow, android assistant for its start up manager, and autorun to delete all 'event listeners' that cause apps to pop up when they like (and there are hundreds of these in the stock apps, I assure you).
I now have 50% more battery life, and it seems to lose a lot less while sleeping.
I installed the CPU speed set thingy (sorry, I forget the name) but I had the problem a few others seem to have because it drained the battery faster than ever while sleeping. I will try again after a few days. I screenshot the battery graph in full screen, showing the WiFi, wake & screen, every day so that I can get a good feel for historical usage and battery life.
I have an el cheapo battery (had two but lost one) for emergencies. I am buying a Samsung one instead (for a 'real' 2500 mAh), and expect to keep it on me at all times. That should take me through a day of pretty heavy usage. I also have some dangly 'add-on' chargers, but frankly a spare battery is neater, smaller and easier.
I have also bout a tablet (10.2" with 16GB) for $200. I fully expect to buy another - one for work and one for home. These will reduce my usage of the G-Note and leave it for actual use as a phone. The main problem is that I use it so damned much! I have my phone, contacts, all my To Do lists, email, audible books, textual books, surfing, games, etc all on one device. I also use it to type notes at meetings or the like using my folding BT keyboard. It does it all really well, but does not have the battery to cope!
I know there are fat batteries out there, but I do not want to spoil the beauty of my svelte Note by giving it a hunch-back!

I also use Llama to control things like BT, WiFi and network data access when away from home or office. It does help, and means I don't have to remember to toggle. I tried Juice Defender as well, but its idea of turning on the WiFi at intervals saved my battery but seemed to make my email (IMAP) never download. I need to know when emails come in so that did not work for me. I may try it again at some point and try to make it work better for me.
Uninstall Juice Defender. I found my phone battery lasted twice longer after I removed it.

I use my phone for note taking all day and into the evening! Screen and internet used for over 12 hours, constant use! (Screen on lowest setting)
After battery "settled" I get around 10 hours then pop in a second battery!
Took about 15 charging cycles though to get the 10 hours!
Anyway just saying it may take time! And a second battery is always safest

that's... actually pretty normal battery usage if you're using your phone a lot.
my note is operating pretty much 18hours a day. A full charge is all i need, and by the end of the day, i get the critical battery notification.
if your note lasted more than a day, that's great. But with the amount of workload i am expending using my note, i wouldn't be surprised if continued usage of the phone would only last 7 to 8 hours tops. or much less.
and besides, the note can last for more than 2 days, if you didn't use it at all.
thanks for all the suggestions...i'm going to give rooting it a go this evening. Will let you know how that goes.

Yeap, that seems like average battery life. If you notice (others) that his screen on time was pretty solid most of the time. That means of the nearly 6 hours on, I'd say about 4.x hours the screen was on. So that's good
I have managed to improve my Galaxy note battery life a LOT by doing the following:
- Disable Wi-Fi when not using it.
- Settings > Accounts and Sync > UN-TICK "Auto-sync".
With auto-sync disabled you have to manually open the relevent app to get the data, but for me, thats what I prefer, and it saves loads of battery life.
Used to be 8 hours or less with the above 2 enabled.
now 16 hours+ with the above 2 disabled !
Installed free version of Juice Defender 3 days ago, didn't do anything just keeping it on balanced mod and from now on I have extended normal battery life (phone, e-mails, sms, occasional internet through 3G) from 1 day to 2 days. What can I say ...
It works. When you switch into wifi, gaming or intensive document editing then nothing is going to save you, but just for having the phone in your pocket and using it as a "phone" Juice Defender delivers.
I noticed on the market that roughly half people say it is excellent and the other half is whining that it just sucks. Give it a try a decide for yourself.
Just turn auto sync off and untick "Use wireless networks" and you will be blown away by the battery life.
The last two days my battery was losing power too quickly compared to my previous weeks with my note.
So I thought it must be an app which I installed which is causing this. The only app I installed recently was Google + so it took it off and hey presto - battery life back to normal again.
You might say well it doesn't drain my battery with google+ installed but it works with mine as I tried re-installing again and it sapped the battery again.
Maybe different apps effect different roms, kernals etc...just a thought and something you could try with a recently installed app.

I can see that as an option, and I believe that all of those who report great battery life are doing much the same. My problem is that I want to be kept alerted to emails. I have tried Juice Defender, as it starts up wireless at defined intervals, but since my email is checking at other defined intervals, at appears that the email never gets through. I have to assume they never coincide.
I also like certain apps to sync, although I guess I could do that manually. Currently I turn on autosync while at home or work with Llama. Luckily the wireless and autosync toggles are in the notification dropdown as well - that is a wonderful idea.
I use the Note far too much, so (as I have probably said) I am getting a tablet. I hope that it will serve as my email notification when I am at home or work. When Llama knows I am at neither place, it can disable autosync and enable mobile data for me (which I keep off at home & work).
It is a delicate balance trying to get full desired operation and decent battery life. I am not sure it is really worth all the agro. I may just settle for a spare battery in my wallet and a dock/battery charger by my bedside. That is probably the easiest of all options! Then I can game away whenever I like without constantly checking the battery
Im using a custom rom rocket rom v21 with abyss kernel... which gives me a battery for 40 hours approx. With fair amount of usage. Sync off facebook app as it sucks a lot of battery too.

Awesome! Been looking for this feature for awhile now. Only downfall is just remembering to switch it back when i'm using Pandora
A bit off topic but I experienced a fluke on my battery life, was just watching simpsons while I had my wifi connected and only had my yahoo messenger connected probably a total of 10-15 messages in 4hrs range, for 4 hours of screen time it normally drains 50-51% only.
I almost always have the same scenario when I watch simpsons on my phone, yahoo messenger running but it the first time to drain it like this.

its good practice to save battery to turn refresh interval for apps that access the web for updates such as social media, new readers, etc to manual to help save battery life as most of these apps refresh on a pretty regular interval and defiantly eat up alot of battery
If you notice especially high battery drain and recently used your GPS or Camera they can occasionally stay on with no visible signs. Also please remember the battery stats is HIGHLY inaccurate. A Phone reboot usually fixes this.
Never keep apps like Skype, IRC, etc that stay running and keep your CPU on they drain battery especially fast!
One big battery saver is to not wake your phone to just check the time. Let the CPU stay in deep-sleep as long as possible to preserve power until you actually need your phone for something.
One MAJOR thing to save power is DO NOT MESS WITH CPU SETTINGS!
Do not use 3rd party apps like Voltage Control or SetCPU or even the built in Performance settings as modifying the settings will increase the minimum clock to 200MHz which will greatly reduce battery life than NOT messing with them. This is a known issue and will be addressed in a future release!

If you DO decide to run a custom kernel, (NOT, I repeat NOT recommended or supported by CM9 devs) I'd suggest Control Freak. I ended up with a 200mhz min, and with that app managed to get deep sleep and 100mhz back. WITH uv and some minor oc. My battery life is great.
Head on over to the app thread here: http://forum.xda-developers.com/showthread.php?t=1072403
Another thing that can save battery, Screen Filter from the Market (Play Store now I guess) can dim our screens lower than the lowest stock increment. Useful for dark environments. (Movies, night outside etc.)
This should be obvious, and has been stated already, but it bears repeating: TURN OFF DATA AND ALL OTHER MODEMS if you're not using them.
Thanks to all the devs and everyone who contributes.
YES!!! It seems a little bit more snappy or is it just me?
And thanks for the advice not to run custom kernels...
Without a doubt, the biggest battery saver for me, is to turn off data until I want to use it.
I simply cannot believe the difference. Makes me think I'm gonna have to go out and get Juice Defender, and let it turn off data when I put the phone to sleep, it is just that dramatic.
I can call text, and play hours of games, and still have the battery have more juice remaining than it did over the same timeframe with just a call or two for usage with the data on.

Rather than installing an additional app to control brightness, why not just tweak the settings yourself?
System Settings / Display / Automatic Backlight
Check "Use custom" and set a lower Screen dim level. Use "Edit other levels..." to adjust the steps for auto brightness if you use that feature.
This is a fantastic feature if you use the phone in low light conditions.

This first and foremost for me.
I took my phone to a basketball game the other night and turned data off. From when I left work to when I got home was about 7 hours, and I didn't plug in for another few hours later and still had some juice. Compare this to last night when I went to class and had my phone in my pocket with 4g on for a few hours, I arrived home and my phone died 15 minutes later. Total time elapsed, 3 hours 46 minutes.
Particularly 4G data is offensive in it's battery consumption.
I have also found that putting the display on Auto Brightness saps my battery. I just adjust it whenever I need to, keeping it on the lowest setting most of the day since I'm inside a lot.
The mmc_delayed_work and deleted_wake_locks are driving me crazy. I know they've been reported as "false blames," but something, whether MMC or otherwise, definitely causes seemingly unnecessary wake locks, and there is a very clear pattern between high report percentage and battery drain.
I don't mean to take away from the optimizations suggested; they're definitely useful if you're looking to stretch the battery life out longer than typical stock capability. But for many of us, something wakes the phone a little too often, and it's very difficult to debug without disabling every single application and testing one at a time.
I guess the point is, has anyone else found a better way to figure out these wake locks?
Why is awake time in Android OS always more than double the display on time? That sounds like serious wake locks. What can I do to reduce that?

Don't overlook the AudioOut_1 wakelock. Its my number one offender at the moment.
Minimize it by turning off screen selection sounds... System Settings / Sound / Touch sounds.
We need to figure out what the problem is with that.
On the good side, my mmc and deleted wake locks are negligible so far on beta.

If I might be so bold to suggest, put a section on your page for "If you get worse battery life on this rom than your last rom, it may not be because of a problem with this rom, it may just be that way and there may be nothing that can be done about it because that's just the way it is."

Just spend a day with CM9 Beta 0. It's a great rom with lots of promise. Great feel and look, very fast, ICS is fantastic.
That said, the battery life is not there yet. I basically set it up the same way I set up the stock rom. Email on Exchange push notification, EVERYTHING ELSE on manual sync. On a stock rom I usually am at about 40% after 12 hours of moderate use. About 5% drop an hour. On this rom I was at 75% after 2 hours. About 12% an hour. This is with the "stock" 1800 mAh battery.
If the devs can match the battery life of stock GB I'll be back. It really is a great rom, I just can't recharge twice a day, and I'm not carrying around a 3500mAh battery in my pocket either.
Seriously, great work to all the devs who have taken it this far. Looking forward to the next couple releases.

I use JD for this and run it in extreme mode, which disables data until you physically enable it yourself (and after you enable it, it will disable again when the screen is off). Using it, I get a huge improvement in battery life, especially on CM9. It's kind of annoying having to enable it everytime you turn the screen back on, especially since it takes 4-5 seconds before data works again, but if it can give me the type of battery life it does, I am all for it. Other than the slightly noticeable lag I get compared to CM7 and other ROMs such as CleanGB (I know I can install supercharger, but I am talking pure stock CM9 here), I have no problems at all. Major props to all the developers involved for breathing new life into our OG Epics.
Hey guys. I'm wondering how much better the battery has gotten since the first week y'all got it, to now.
For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.

Are you taking any measures to save battery life, like certain screen brightness, disabling of certain features or radios, undervolting or CPU/Governor changes, etc?
First thing I installed on mine ( haven't had mine a week yet ) was Battery Monitor Widger Pro, since I've used that on my past devices when I was testing out generic batteries (speaking of which the 8$ ebay 3800mAh on my Desire-Z is still kicking strong after a year).
Problem with estimates, is that they are basically just that, and the difference between browsing on mobile vs browsing on wifi or mix, and your reception quality can also have an impact on your battery. (in the end, your screen is the biggest impact).
Mine lately, say if I had it charged at 100% , it'll take about 2 hours on mobile to get to 91%, with the screen being on about 25%-35% of that time (auto-brightness), receive/send text, take out of pocket to check email or facebook notifications, and so forth. Which would normally show as screen 30%, Google services 13%, Wifi 9% (when I had it on between house and destination). Phone idle 8%, Android OS 7% etc.
The widget I mentioned earlier can basically monitor your draw from time to time and if the screen was off or on and such during those times (default interval on it if using a widget is around 10 minutes on the logging, shorter may actually impact the battery it's monitoring oddly enough)
PS: The other day when I actually drained it down to 0% it took about 5-6 hours

I had about 3-4.5 hours of screen time other moderate to heavy usage on my first week as I was testing it's battery life. As that I just used my phone under light to moderate usage. My brightness level is always at it's lowest but when I'm outside I turn it up to about 50%. I rarely play games on my device. I read a lot on my phone. I use my phone to record lectures in class and do a bit of homework on it. 7 months later and I'm pretty much doing the same. I have a custom kernel installed and I'm really confidence about it. I carry a external battery pack with me all the time but I hardly use. After having a custom kernel for the past 7 months I can say battery life has been relativity the same screen time wise. I learned how to manage my apps so they won't prevent my phone from sleeping to save power. Your mileage will vary depending on what you're doing on your phone and how you manage your device. Cell service is crucial to the phone. If you're in area with little to no service your device will use up more power to stay connected. This is when "Airplane mode" comes in handy.

Nah. All stock, not rooted yet, auto-brightness, No auto sync. I don't get very good service at my work and I was about 28% without service during the time I was there. I would get on facebook and message people on facebook and text, surf the internet etc because it was slow. I had maybe 2 hours screen time and 8% battery life when I left work. It was probably 9 hours off the charger. Here. I'll post a screen shot after this post (On my computer right now)

One of the benefits to custom roms (though 'stock' on a nexus is well AOSP so...) is the ability to tweak that stuff to finer details, top it off with a custom kernel and can optimize even further. Just a matter of how far you want to take it.
I have a history of immediately rooting anything I get my hands on, so I tend to have very little experience with stock. But the Nexus devices are probably the only ones I could survive having stock (but rooted) as opposed to say touchWhiz on samsung.
I can say that this phone charges FAAAAAAST.

Guess tonight I'm going to work on getting it drained down to 0% just remembered it was my N7 that I did a full cycle on with monitoring, I haven't done so yet to the N4.
PS: I usually do a dual-graph (mV and mA), but in this screenshot you can see generally speaking with my current configuration, I tend to drain around 200-300 mA screen on, and around -20-50 with it off.
PS#2 : It only went up to the -400 or so mA on the top right because I had changed my screen brightness to about half instead of autobrightness.

Additional options. Take for example the Bricked kernel for the N4 in my signature. This is it's feature list, it's not aimed for hardcore overclockers or such but gives you some options (The one for the Nexus 7 is a bit more configurable during the installation).
* Based upon Googles msm 3.4 source
* Various other fixes (look @ github)
* Compiled with gcc4.7.2 toolchain (linaro 09.12)
* -O3 optimized
* Snapdragon S4 & CortexA15 optimizations
* Sweep2wake
* 192Mhz min clock
* replaced qcoms hotplug binary with msm_mpdecision (IN-KERNEL, better battery life + performance)
* Extensive sysfs interface for mpdecision with all the tuneables you want (/sys/kernel/msm_mpdecision/)
* replaced the thermald binary with my IN-KERNEL solution. (/sys/kernel/msm_thermal/)
* export krait version to: /sys/kernel/debug/krait_variant
* modified ondemand governor
* Allow OC up to 1,83Ghz, faux123 (from a thermal point of view that is now SAFE)
* Fixed min cpufreq resets
* Undervolting (faux123)
* Default clocks: 384min & 1512max

Sweep2Wake is kind of nice too, you just slide accross the screen to turn it on without having to touch the power button (And yes your phone is still asleep doing this, it just works off interupts.)
other kernels can be a bit more involved, such as being aimed towards overclocking the CPU or GPU, or adding in extra features not normally found in stock, and so forth. I've had the best luck with Bricked and Francos'

Yep, if you have a widget on the home screen (I usually do 2x1 size) it'll collect every 10 mins by default. If you don't use a widget you'd have to check a box in preference to monitor without widget or it won't log times (note for example the missing 'blocks' from my history log).

Speaking of battery, anyone ever gotten more than say 800mA charge on their N4? Cuz even on my old Desire-Z if I plugged it into a 2.1A charger it would actually charge up around 1300-1500mA, but with the Nexus 4 seems that even on a 2.1A port it rarely charges more than 500-600mA.
It'll probably become more accurate once I actually drain it down to 0% and have the widget record it's history from 0% to 100% since it bases a lot of it's mA estimates off that (ie: off the rate of decrease of the battery's mv since batteries typically have a certain voltage once they hit near 0% and when they're at 100%, comebine that with what it knows the battery's mA to be it can determine the charge/discharge based off that).

Just in the last 2 hours or so, probably 30-45 minutes. I was in the car so it wasn't coming on all that often. Since I actually have the widget on my home screen now, I'll just post an update again probably in the morning as I play with the phone some more, maybe play a game or two (I'll set a Market in the battery history before I start and after I end it).
Far as figuring it out, it's pretty easy since most of it is already set up by default once you open it. You can basically just pop a 2x1 widget on the home screen and just leave it.
My battery life has improved drastically by just sticking with one setup and letting the phone get used to it. That means keep the same rom and kernel so the phone settles in and gets used to it. After a few cycles your usage should increase.
I recommend straight CM 10.1 with Franco kernel.
Also use 2g instead of HSPA+ when you're not using data to save power.
If you're using touch control, don't, it drains more power for sure.
Undervolting helps too.

Can you clarify on this, other than the power/volume there's not much else to actually control the phone with.

The app 'touch control' , many nexus 4 owners use it to wake and lock the phone using touch gestures in place of the traditional power button. In my usage it definitely drains the battery quicker.

Oh you mean like Sweep2Wake in the Bricked Kernel I'm using, except that doesn't use any battery cuz that's in the kernel using interrupts rather than an app that would keep the phone awake. (course that's all it does too, wake, nothing more sophisticated than that).
But yea I didn't know about that app.

Got this phone about 10 days ago and my battery is terrible since day 1, someone suggested to root my phone and get the BBS app and dump a file i did that and installed a system tuner to disable google CHECKIN OR GCM and unchecked them. apps i got installed to help with battery battery doctor, wakelock detector, os monitor, system tuner, gsam battery, betterbatterystats.
Apps i disabled are:
Ant radio service
Ant+ plugins
App zone
Blurbcheckout
chaton
chrome
flipboard
google play book, games, movies, music, newstand , google search, google+ , hangouts
hp print service plugin
my magazine
s health , svoice , samsung account , samsung apps , samsung galaxy apps widget, samsung push service, smart remote , Top Hd Games
got a plain black wallpaper, even after all this i cant get more than 2h30m screentime and everyone is getting 5h+ do i have a defective unit? what are my options right now? cause basically i removed everything the phone has lol. i talk to my workplace and they can send the phone for repair but i want to see if someone can help me before i do that. i have to unroot the phone if i have to send it for repair even though my phone is 0x1 on knox cause i was stupid to root with cf-root and didnt check other methods.
After all that you did, then it sounds like a faulty battery or device.

How's your signal at work? I'm on 3g at half signal maybe? I get about 3:30 and standby. But when I'm at home WIFI only I get about 4-4:30 it all depends too on how bright your screen is.

How do I check if I have a good signal at work? Through an app or through a battery status.

This system tuner app you used it not any overclocking or something that might drain you battery?
What screen brightness do you use most of the time?
Can you see what use most of your battery? There is charts you can access in settings -> battery
I run with BLAZE kernel and Alliance ROM. (install without any samsung or google bloat if you can)
And I have been using my phone constantly, playing streemed music, installing apps, downloading from internet, browsing internet, having screen active a lot...
And Now I'm at 87% and have been running 1 hour and 38 minutes on battery. (Was at about 100% battery before)
I run +5 screen brightness and don't have any special powersaving features running that limit my experience with the phone.
You could try that kernel and ROM too, I feel they improved my battery time a lot.
I also shut down some samsung and google bloat stuff like air browse, s voice and such crap, saving a little little battery.
Here is my battery info and my brightness level. I have Canadian g900w from Rogers so I am not sure what roms or kernels you can use ?

Hey, here I have everything turned on and I never followed these stupid extreme battery guides and I easily get over 4 hours of screen time and one day away from the charger. I only use auto brightness, Greenify and KT Kernel.
It's a smartphone, if you're supposed to turn all the features off then you should have bought a dumb feature phone.
Looks like ur using max brightness? Nearly 2 hours screen on time for 44% isnt the best but isnt terrible. I get around 5 to 6 hours using low brightness 3g/4g on besides when screen on. Using android tuner and greenify for tuneing. Screen uses a lot of battery to. Im using. Ktoons kernal now with oc and the batterys probably the same to to me. No beter or worse but. Im running higher clock.

You're set for almost four hours of screen on time there, on what seems to be very poor mobile signal. Doesn't sound that unrealistic to me to be honest.
Poor mobile signal absolutely kills battery life, as your phone spends the entire time searching and trying to get a better signal.

I think his point is that most people get 5-6 hours screen time with everything on and without following the "stupid extreme battery guides". To be honest it looks like you aren't getting great life either if you are only getting 4 hours. I regularly get 6-7 with everything on and no greenify or kernel tweaks

I see a couple of things interesting with your setup, Speaking from personal experience, I too have had battery issues drive me up a wall. I'd get just about a day on a battery when everyone else gets about 3-9 days more. My friend has an s5 all stock and he gets 9 days on a freaking battery. WTF
I rooted my first s5, with ANCH baseband and still couldn't solve all the issues with it. So I sent it back to t-mo and they sent me another one, getting batteries on ebay has also ended up a wash. 2 batteries I've received go down 20% from a full charge in the first hour and shut completely down at 32 percent at least I got a refund on that. (So be careful about ebay batteries, even though they say samsung.
So looking at yours here's what I see, Your system is staying awake, lets look at wake locks. Kik is really tearing up your machines wakelock (900wake locks) as well as the camera CPU time, i'd imagine you were recording a video at some point.
1. Go get greenify and greenify those Kik, Instagram and camera apps if thats usage while the screen is off. (No notifications on those apps, i'm afraid when you do that.)
2. Go get system tuner, make sure your rooted by towelroot (If you so choose to keep from tripping knox) and go into app mgr and find android system and go through activities, receivers and services and make sure everything you see that says IQAgent gets unchecked. This will help you stay out of ServiceIQ's eyes and also help your battery as your entire phone is debugged through those apps. (Help is on the forums somewhere)
3. Turn off google now, hotword detection and location history or you'll start noticing Google services draining your battery
4. Go get deep sleep battery saver and remove that battery saver, I personally never liked it it only suggests things to do rather than do them for you. At night or whenever you need to save your battery turn on slumber and it will only take like a percent to 5% in the morning
5. You probably have a bad battery, especially if its down to that low. Time to exchange or return
I'm incredibly disappointed, i've had to do all these things to really figure things out, heck i'd be on firefox for about 15 minutes and go down 18% (Happened this morning)
Android really has some issues with kitkat, and even though we try and fix these problems with modifications there comes a point where one just gives up and tries to deal with it.
I don't understand why my phone gets 1.2 days and my co-workers Verizon s5 gets 9 days with normal usage. Everyone seems to have crazy all over the scale battery life results. Heck, i've reset my phone and flashed so many roms that i'd be safe to say that I have yet to have 10 full discharges in the 4 weeks i've had the phone. At the end of the day though, it's mountains better than my iphone 5 with a lenmar battery case.
Wish I could say the same with stability, I'd be on my bike and switch tracks (or try) and stuff just doesn't respond, heck I can't even go with voice activation with wired headphones and that is really a downer for me. I want to be able to hold down the pause and play and get the google now boop boop sound and speak as i'm riding.
I'm tired of this, and google has no answers, the fixes above only seem to add a couple of hours but not the 9 days I was seeing.

Gtalk, whatsapp, line, google drive, dropbox, gmail, Yahoo mail, corporate mail, all running. No greenify. No battery saver.
Now playing games is different thing. 2-3 hours max.
My battery is amazing. I keep the screen brightness lower, keep networks and chips off when not using, i use bootmanager to prevent apps from launching ay boot and only 1 active widget. Good for a day and a half of very fair use !

Hey guys! I hope you're all enjoying your new Priv! I got mine on release day, so I've been tinkering with it since I got it. A few things bothered me about the device: the battery would take forever to charge, even using a Qualcomm certified quick charger, and the battery would drain abnormally fast. Even with no apps running, Antutu would only score 40,000 to 50,000 and 800/2500 in Geekbench.
I found out that the T-Mobile MyAccount app was always running in the background and took up 6% of my phone's battery, just above android OS. After I disabled that app, I found that a full charge would only take about an hour, versus the 2 hours it took before. Battery life also skyrocketed from about 8 hours to 14+. Antutu scores went up to 60,000 to 67,000 (I tested several times) and Geekbench now consistently scores 1200/3500 for me. The phone also doesn't get NEARLY as hot as it used to.
One other thing I did was to change all my accounts in the hub to sync every 15 minutes instead of push, which also seemed to help with the battery life. Hope this info helps you turn your Priv into the best phone it can be!

I heard that some people on Blackberry forums were reporting that T-Mobile My Account app could/is causing battery drainage. I didn't like my account app showing me notifications and went to options in that app and remove all the check marks from the there. I had no issues with battery, but as a precaution I always disable apps that I never use.
Thanks for the heads-up. Finally picked one up today and felt that it did indeed heat up quicker than it should and definitely wasn't charging as fast as I thought it should be. Hopefully this helps!
My Priv's battery has been an utter nightmare - gonna give this a shot. Have you noticed any adverse effects from disabling the app? My main concern is if BingeOn will still work. I'm okay with not being able to disable it (not a big video guy) but free music streaming is super important to me - streaming music at work constantly during an 8hr shift, in the car during my commute... yeah, I need that.
And, before anyone says anything, it's not the music streaming doing it. In fact, the battery seems almost better when I'm doing that since I've just got the phone sitting in my pocket. Wakelocks are an absolute nuisance though - "awake" time is well over 10x SoT.

BingeOn doesn't require any T-Mobile bloat to run. It's handled on the network side, not on the device itself. Also, unless they recently changed something, you don't need BingeOn enabled to get free music streaming. Music streaming is free regardless.
Thanks for that. So far the Priv is doing a fine job keeping itself alive now that app is gone. Nice to know I won't be blowing past my data allowance. I'm new to T-Mobile and so far, so good. Well, other than their app destroying my phone of course.

You'll get all that bloat with any carrier
I do want to point out that the Priv does an awesome job of standby. It makes sense that a 2K screen could drain the battery quickly, but I've gone 9 hours with only 40% drain when I barely use it, so it stays alive well when you aren't actively using it. I was also streaming music the whole time, but since the screen itself was off it saved my battery.

The screen is a killer on this device, but it shouldn't be quite that bad. Are all your BlackBerry apps up to date? Some people have to manually check for updates for some reason.
Also, I disabled every T-Mobile app except visual voicemail. No idea if that'll help or not but it's worth a shot.
Finally, how long have you had the device? Phones always seem screwy battery-life wise during the first few days, regardless of system health.
I disabled all bloatware, this phone dies WAYYYYY to fast compare to my prior note 5.
I really dont, but i'll need to trade back in this phone if I don't get this solved. A man needs a phone with a battery!

I'll take back what I previously wrote, as of yesterday I managed to get 24 hours on phone battery. at standby this phone doesn't use any sort of battery, I killed 20 percent in 40 mins on youtube though..
Going to give it a solid week, if not i'll return it and hopefully pick up the new s7 if release by then. I was on the same boat as you, got tired of the note and just wanted a switch. I'll keep checking back leaving my reviews here

I'll second this - screen off, next to zero battery used. Screen on, battery tanks like crazy. I think I'm gonna stick with it though I'm tempted to give the V10 a shot - I need a tough phone and this most certainly is not.
