Hey Guys,
So I have been using the one for about 4 months now and battery has not been up to my exceptions...
I know, this thing has a quad and pushing more pixels but it has a 25% bigger battery too (1730 vs 2300). What I want to know is if there is a Rom that'll turn this phone into a 1.2GHZ DUAL core, thats right, just literally chop off 2 cores at ALL times to boost battery?
Haven't rooted the phone yet but this battery situation is wanting me to do that.
This is from experience but HTC EVO 3D got 18 hours after good amount of use and almost two years of battery use (rooted with a good kernel) vs HTC One with 10 hours with "fresh" battery (stock).
Thanks
Why would you want that??

That will fix the battery issue if you don't mind it being bulky
Yeah, why cripple the phone when you could cripply your wallet AND the aesthetic of the phone!? Haha.
All seriousness, what kind of battery life are you getting?

Would need kernel source to make a custom kernel to shut down 2 of the cores
Sent from my HTCONE using Tapatalk
Root the One before trying to shut down cores. I had the 3D and this phone has much better battery. 10 hours is like 25% with decent use on the One. Something not right off that is what you are getting.

Use cdma only in your mobile settings, This phone gets way better battery life than the 3d

Just underclock to 1.1 ghz
The cores support hotplugging. They are off if not being used. If they are being used, then they are being used to do something that will finish faster with more than two cores, in which case having two cores would give you less battery.
What you want is similar to people who want like 56mhz low power states. It consumes the same or more battery. If the phone could get literally free battery at the cost of just disabling two cores permanent...don't you think they would do that?

So if what your saying it right, then why haven't phones increased DRAMATICALLY in battery life with these humongous batteries?
I will root the phone as soon as KitKat ROMs are released.
I've had the Evo 3d and i don't see how you got better battery on that thing. Don't bother with turning off cores, it won't help cause the other core will just be working harder. if you really want to try to save battery, underclock or use the power saver mode with "limit cpu" option. Either way, the biggest use of battery on this phone is not the processor, it's the screen.
Yeah I also had a 3d for a long damn time and I have no idea how you're getting worse battery life. My one gets around 3 hours screen on time. Lucky if I got an hour and a half with the 3d

im with the others i have no idea how with the same use the 3d is lasting longer than the one, i use to have to charge my 3d by 1pm cause it was dead, the one can go all day and still have 15-25% when i got to bed.

I think you are right, the screen is sucking down the power, maybe I should get a lower res screen (Moto X?)

Will definitely be rooting as soon as a good KitKat ROM shows up, what is SWG?
To give people a reference to the awesome EVO 3D battery I had, one night (8 hrs no use) I lost only 3% battery! Compared to the HTC ONE I have lost 46% on standby over time
So obviously my next question is about screen res, any options to decrease screen res in certain ROMs or kernels?
You must have a rouge app or something. I recommend either finding what it is or doing a factory reset. The screen takes a lot of battery, but not that much. Also screen doesn't matter in stand by time.
Sent from my SM-P600 using Tapatalk 4
I agree. You need to see why yours is not sleeping well. Just as an example, I didn't use my phone for 9 hours while at work today, and my battery was at 91% when I got out. It seems as if yours isn't going into deep sleep when your not using it.
Also, I don't believe the display drain has to do with the res but more the screen backlight brightness setting. I have noticed that if I turn down the backlight when I can, it saves a little on the battery also. I've also noticed on mine that the WiFi being turned on is a big battery drain. I have my WiFi "sleep" during long periods of inactivity.
Good luck, YMMV

I see what you guys are saying. Let me factory reset the phone first, since rooting is such a pain these days. I will report back.
I might have a battery issue, so rooting can be problematic if I wanted a warranty repair.
I decreased my screen resolution and my battery life is amazing
My 3D had about the worse battery life of any phone I've had to be honest... If your One is getting worse than the 3D you likely have something set up wrong or poorly that is draining it.... Check your wakelock times on apps.

hi guys im running firebird rom and my battery life sucks really bad. i take it out of charge at 10am and it dies around 4.30pm so does kernel makes battery life bad?
my kernel says : 2.6.32.9 [email protected] #28
please share
Depends. Some kernels are overclocked and will use more battery. Some are poorly put together and will use more battery. Some may not work well with one ROM, but great with another. Not knowing what you do with your phone it is hard to point a finger at the kernel. Poor reception, lots of wifi on time, lots of screen on time, GPS use, push e-mail...lots of things take battery. You need to see what it is you're using and whether that and not the kernel is your issue.
Short answer is yes, kernel affects the battery. All you can do is try a few different ones and see which is best for your usage.
im on messenger services and about 40-50 text and 3 mins of calls and my 3g on and brightness all the way down. no gps no bluetooth or wifi. i use the phone pretty much straight from 10am with maybe 2 mins here and there screen off

Well, what more do you want? With that kind of usage I doubt you can do much better with any ROM.
that kinda sux but if the screen is really on that much it is normal, i dont think any rom has been tested to surpass 6 hours screen on time.
one good rom was andromda with which i had a hard time running my battery down in a single day, usually went 2 without a problem and i do a lot of texting. also an old version of perception built off a bell vibrant i9000m rom was outstanding.
kernels affect battery life but clock speed on the cpu has less to do with it than many people think, the assumption is faster cpu speeds means more power drawn but the cpu is governed, the governor setting have a lot to do with it. think about it, is it better for the cpu to take 4 seconds on an operation @ 600mhz or do the same operation in 2 seconds @1.2ghz? depends on alot of things reallly but thew difference is alot smaller than people expect. there is also kernelhz which i dont know much about but reportedly if set down to 100 to match another frequency(cant remember off the top of my head) will increase battery life.
the kernel controls many aspects of the system but i haven't seen a kernel that has had a huge increase in battery life given the same rom since the 2.1 days. and even then the battery life wasnt as good as a couple of the 2.2 roms. it seems to me that the rom has more to do with battery life. some vibrant ports have severe battery drain issues on the captivate. some i9000 ports have amazing batery life but most are about the same as stock to slightly better.
if battery life is a problem first you want to see if any processes keep the phone from sleeping. figure out what apps show in the running process list and try killing them, if they don't die/they start back up then freeze them in titanium backup and see if anything makes a difference. careful freezing system processes, some are not detrimental, most are.
other tips are to try apps that manage 3g like juice defender. and use wifi when you can 3g is a bigger battery hog than wifi. also there may be a way to set the phone to default to edge instead of 3g but i think it varies with the build of the rom, you will have to research that one.
other things to look at is weather you sync to google, facebook, twitter ect. those feeds widgets can eat battery as well as the sync process. weather widgets like beautiful widgets seem to have an effect on some of the vibrant ports i used but not as noticable on other roms.
Yikes...that is some awful battery life. I'm surprised because speedmod (and it's variants) is pretty well accepted as being the best kernel for battery life. There are many threads around here for improving battery life. I have personally found that my biggest battery user was constantly checking how much battery I had used.
If you are barely turning your screen off that is good battery life. You will never make it much past 5hrs screen time. Where people get like 40hrs on a charge is when the phone its not actually used, and their set up has good standby performance

When I used assonance I would get three days of battery life.
Sent using smoke signals.
As some have said screen time is the single biggest battery user. My phone will last for about 3 hours of screen on time. So I could have my phone die in 3 hours, or 2 days, it all depends on how often I'm turning that screen on.

Not if you're in a bad reception area.
This is what I average on Andromeda. Some wifi, some GPS tracking, lots of music streaming via BT.
Of course, nearly everything comes into play. Modem, ROM, use, etc.

I picked up my Nexus 4 yesterday and got everything setup. The stats I posted are only from today, coming from fully charged. I have not updated to the latest OTA yet.
You will notice that after 9 hours, I still have 40% left.

A good portion (about 4 hours) of the day was spent inside a building that results in poor reception. As a result, there should've been more battery drain during that time. Also, I have wifi enabled almost the entire time.
The screen was on for almost 2 hours.
The Nexus 4 gets plenty of deep sleep.
Some notes about my activity. I listened to music through a bluetooth headset for about 20 minutes. I sent and received over a 100 text messages. Wifi was enabled and connected almost the entire time. Autosync for email, contacts, calendar, facebook, and twitter are enabled. I have Tasker running in the background. I played around on some social apps (Facebook, Twitter, Instagram, etc) and downloaded/updated a few apps.
This is probably light to moderate usage in my eyes and would easily get you through an 8-hour work day. Battery drain was between 5% and 7% per hour, depending on when during the day you calculated it. It usually averaged around 6% drain per hour though.
I'll probably take a few more screens of my stats tonight before updating to the OTA. I'll then report back tomorrow with similar screens to see if the OTA helps battery consumption at all.
EDIT: I have posted updated stats on page 5. These will include stats after the OTA update.
Thanks for this! With all the backorder emails going out I'm definitely going to wait a few weeks before I decide if I'm going to order one. If I do it will be hard to part with the 3100 mah battery in the Note 2. You can't kill this thing!

Keep in mind it should get better after 4-5 cycles. It's certainly not groundbreaking but it's also nothing to sneeze at. With some monitoring you should have no problem making it through a day without charging. I don't like monitoring though, which is why I love this Note 2

That's actually not too bad. Like thegregulator said, it's decent and will get you through the day. Also, I think my battery drains more when signal is bad, and you will notice that I'm in an area with really bad signal for a good portion of my day.

I wouldn't say it is terrible battery life, but I would say there is room for improvement.
Again, keep in mind I experience a little more battery drain due to poor reception. I saw someone else post a screenshot reaching 18 hour battery life, with almost 3 hours of screen usage.
Hopefully, the OTA provides some better usage times. I'll report back again tomorrow afternoon.

This is really bad. I often reach 6 hours of screen on time on my GS2 with a 2000mAh battery.
I don't understand which part of the Phone is draining that much power,
IPS panels are usually pretty efficient, the S4pro if not pushed should not drain that much either.
The only reason I can think of is that the CPU is spending too much time at the max clockrate with multiple cores online.
Can someone post a screenshot of CPU spy?
I would be interested to see what the battery life is like in airplane mode over a few hour period. One with the screen off (more than likely in deep sleep), the other with the screen on. If the problem is in the jelly bean kernel that can be fixed on xda. If it is the screen draw that is a little different. I have full faith in the developers on xda.

My gut says that the kernel could have used a couple months more cooking time. The hardware is way too efficient for these performances.

You did, but he can't see how much time was spent at the highest clock rate. Looking at those shots, it seems like your phone isn't going into deep sleep nearly as much as it should. Maybe check your wake locks and see what's keeping it awake?

There is only one thing that I find really important in any mobile phone: battery life.
Please post the battery benchmarks and real world experience with battery life in this topic. I am especially interested how it compares with the Samsung Galaxy SIII, HTC One X(+) and Apple iPhone 5 in normal day use.
Agree. I'd be very interested in hearing this. Everyone raved about the S3's battery life and I found it really average.
i think the battery life will not be very good thought the XZ have FHD screen
A good italian reviewer said that the battery life lasts only 10-11 hours under heavy usage WITH Stamina mode on, LTE and HSPA+ turned off and push notifications on via 3G from mail, Whatsapp and a couple more apps (you can decide which app has the permission to keep on running even in Stamina Mode). He also says that the LTE module kinda warm the device under stress, the viewing angles kinda suck and that there are mini lags in the UI (problem solved using Nova Launcher).
you can disagree with me all you like.
but to me, there are far too many problems with this phone, and like i say, i think it is outdated tech.
there will be a lot of disappointed people out there.
and battery life is by far and away terrible on this phone.
i've used it.
i can guarantee you will be charging this phone up every 4 hours, unless you know, you don't want to have the screen on at all.

Yes because you have clearly used the phone. Think I'll believe my own hands on with the device with the half hour I had and the battery life wasn't that bad. If you want bad battery life then go use the Nexus 4 or One X - The One will be the same. Go back over to the Samsung forums with the rest of the mindless sheep. Samsung fans are no different from Apple ones. :good:
I tried out phone calls in the three store today nothing wrong with it atall.
So, any real battery tests by users?
Battery life is Decent,
Screen according to the Docomo units and xiFIL is brilliant and nothing to be ashamed of, Viewing angles as proved in the Xperia Z screen discussion thread is not much oof a problem, although samxool likes to look at his phone sideways
Battery is replaceable, just give it to Sony within the 2 years and they will change it for you if seomthing goes wrong, failing that i am sure guides will pop up how to remove the back cover
terrible phone quality, DO NOt judge a phone when you have never used it,
HTC M7 HAD to be clocked higher with the SAME processor as Sense is laggy and slows the phone down,
Samsung octa core propoganda clearly got to you, its 4 + 4 processor, two quads, they do not work together, only one quadcore will be active at any time,
Out of all of the posts here, none had anything to do with the thread. It was all off topic. PLEASE guys, if someone says something that gets under your skin, don't respond to it, report it. Or just move on to another thread

Using the Z yesterday I had over 9 hrs of use with 3.5 hours with the screen on (about 20 minutes of that with full brightness, rest of the time I had it about half brightness), 4g data, wifi and bluetooth on all day, facebook and twitter syncing every hour, email every 30 minutes plus a gmail account for push email, gtalk running full time, about 6 accounts syncing also used the camera a little bit for burst shots before I plugged it in to charge when I went to bed. Still had around 20% left. That is without the stamina mode on or any other battery saving features.
This phone last so much longer than my ion or TL. I don't think there is an issue with battery life here.

That's actually pretty crap screen time. Nexus 4 and HTC One X times... This makes me sad

My Note 2 lasts only 5 hours with screen on, and it has 3100mah. Most smartphones last 3-4 hours of screen time... since when average is crap ? It's just that - average, nothing special, nothing amazing.

Same here, my Note 2 on average gives me 5hrs screen on, at a push I can get slightly higher but my brightness has to be really low. Those shots above look good to me, they are without stamina mode on aren't they?

Since my iPhone 5 manages 6/7 hours. (And no I'm not a apple fanboy) 3h is rubbish! My S3 managed just over 4h and i know the Z has a bigger screen and resolution but no excuse for putting small batterys in phones that have big screens and high res.
What if you want to compare your battery life with other people using the same Nexus 4. You can do a subjective assessment like the ones in this long tread http://forum.xda-developers.com/showthread.php?t=1992627&highlight=battery . But every body uses their phone differently and have different programs installed.
I was thinking what could be a good test that complies with the following:
• Be Simple
• Be Repeatable
• Be Comparable between users
• Can spot hardware failure in the battery / charging system.
What do you think of this procedure
1. Backup your phone
2. Charge it 100% and keep it plugged
3. Take out your SIM
4. Do a factory reset (wipe/format)
5. Do the initial configuration skipping everything (no simcard, no wi-fi, no google account, no name)
6. Go to display settings and set brightness to maximum.
7. Turn off Wi-Fi
8. Shut down the phone
9. Disconnect it from the charging cord
10. Turn on your phone.
11. Click on the clock on the home screen and start the StopWatch.
12. The stopwatch screen will prevent the screen to turn off.
13. Wait for your phone to die and record the time it lasted
14. Share how long it lasted in this thread
This would be a synthetic test (does not resemble a real usage scenario) but also is comparable and repeatable because does not measeure a lot of variables or differences between set ups.
RESULTS:
First charge
Battery time 6h 02m
Here is a screen shot taken just before it died.

Second charge
Battery 5h 53m
And an screen shoot taken after charge it again and then turn it on
I can only explain that the in the second charge the battery lasted less because in the first charge I left the charger connected a couple of hours after it reach 100% but in the second charge I started the battery test the moment It showed reached 100%.
It just died at 6h02m. This is for the first charge of a new phone. I really don't know if this batteries have to be conditioned or not. I will ran the test again tomorrow.
Hopefully someone can replicate for the test to be useful.
6h with no use ?

I have gotten about 6 days standby, and at the end of the night my phone is at like 50-70% with moderate to heavy use. I am impressed, I don't see why everyone else is having problems

jeeeeeeeeeeeez... 6 hrs of stopwatch... doesn't mean NO USE
this is interesting though... I will keep reading this thread
All this means is how much time your screen can last with little to no use, factor in network,WiFi, and processor and that number halves
I generally get through the day with 60% juice left, and that's more than enough for me. I feel no need to compare with others since real life usage really varies greatly.
A day at work for me is 10hrs. When I'm at work I set my phone in my locker. When I'm on break I'm on it constantly reading reddit, xda, Facebook and Twitter. Usually get about 2 hrs sot using just data and leave work around 50% get back home and use wifi and get around 4.5hrs by the time I go to sleep and charge. With my old epic 4g touch I'd only get a max of 1.5hrs and that's while using airplane mode with my phone in my locker. I'm fine with how long this phone lasts...

Might try this when I get the time. I've tried a lot of different things and cant get more than 3 hours of screen time on a single charge. It Usually gets me through the day but not always.. standby seems to have improved with 4.2.2.. But when I read about all these people who get 5-6hrs of screen on time with similar usage I'm obviously going to feel like somethings wrong since I have the same phone.. So yeah, I'd like to see if on a standardized test we get the same battery.. then we can slowly narrow down other factors to figure out whats causing the difference.. Cause even with battery stats I dont know why mine isn't lasting as long as other peoples..
Comparing to my iPhone 4S
When downloading apps and browsing the web and stuff, I give the edge to the iPhone. I can stream Slacker Radio and browse the web for about 4-5 hours before hitting 20%. The Nexus only lasts me about 3 1/2 hours. Not a big deal.
Standby also goes to the iPhone. I can fall asleep at night and wake up with about 3-5% drain. The Nexus is about a 10% drain.
The Nexus wins at charge time though. I can fully charge it in less than an hour. The iPhone takes at least 1 1/2 hours.
The Nexus also wins with WiFi. I see no difference in battery drain when connected to WiFi or it turned off. The iPhone takes some noticeable drain when using WiFi.
I give the trophy to the iPhone. Although Android completely voids the inferior battery. Nexus > iPhone.

This thread is an interesting idea.
For those with poor battery life check the [BATTERY IMPROVEMENT] thread in this section. This phone went from my worst battery life phone ever, to my best.

Yes I read OP, every single word. But what I'm saying is that if your battery life is great and is enough to last you a whole day, there's no need to check the battery life.
Updated results
I have updated the original post with updated results.
Hopefully someone do the test for comparison.

Actually theres a great reason to check. If you can make it thru the day with a phone with a crapped out battery, that wont be an issue for you but it will be an issue for the next person who owns your phone. It matters because of the resale value of your phone. If you can get an rma that will benefit the next owner, then you should do it just so that it sells better in the future.
So you run the test and find out your phone is damaged on arrival even if you didnt notice at first, and you get it replaced.
It would be very interesting to find that everyone's battery lasts approx the same lol under this situation.
The only limitation of this method is that we do not take into account any leakage of a certain, a more or less efficient processor or modem on someones phone.

It is funny because this is actually why I crated this test. This phone is a RMA replacement of the one I had before with battery issues. It was a pain to know for sure if the problem of my previous Nexus were SW or HW related in this forum I only found subjective opinions on battery life. Nothing to compare and be 100% sure it was in fact a defective battery and not some misbehave app.
So at least I now have a base line to compare if some battery life problems arise again.
Waiting for someone else to run the test to see if results are similar in other nexus 4
So with just stop watch & screen on the phone is getting 6h total time ?

Hi guys. I just bought my phone today installed all the apps and then fully charged it. However I am getting poor battery life. What is causing my battery to be crap? I don't see what the issue can be as it is a brand new phone. Coming from the sony xz premium i feel as if its a downgrade on the battery end of things. Does anyone have a suggestion
I thought my battery was terrible at first when I got it. I noticed lately I have not noticed so much anymore. Right now phone been on for 2 hours straight and lost 25% with brightness half way. Just give it time

It scares me that battery life is not going to be any good and I have to hunt for the charger through out the day. With my xz premium with about 4 hours usage i normally had 40 to 50% remaining. I don't want to think about charging my phone just to get through a day. Lets just wait and see if it gets any better

Android needs some time to adapt to your apps.
I bought my Note8 three days ago and don´t used it permanently respectively don´t have so many apps installed.
I charged it 2 days ago (at 18 o´clock it was fully charged!), now I have 48%
Before I bought my Note 8 I had a Mate 10 Pro with 4000 mAh and 60-70 apps. Android needed 3-4 days to adapt. In the first days I had to charge every day. After a week the Mate 10 Pro had to be charged only once in 2 days.
So do not worry!
Watching this with interest. Mine is a week old and I feel like I need to keep topping it up. On the road all day today and worried she won't make it!
I've a charger in the bag. But going to see how far I get!

Thats what i was saying while i have the chance i might return it and get the Pixel XL 2 or the mate 10 pro. I believe both have better battery life. The pixel loses out on screen quality but makes up with software and battery life. The mate 10 pro loses on software but kills it on battery life. So tough choice to make. However i can't stand poor battery life especially never having to worry about battery life on the sony xz premium
Had mine since day one and the battery gets better the longer you use it. I have several things disabled that are big battery suckers - Bixby for one, don't want or need it. I can go 1-2 to days of moderate use, using an ereader app but no game playing.

The better question is, what apps did you install? You need to just use your phone for a few days. It will begin to background/sleep apps you aren't using which will extend your battery life.

Man those are battery hogs galore!!! Use the device for a few days and let it adjust. Did you enable the sleep function during setup?

I had these apps and more running on my xz premium but i had great battery life. So I don't see how they are battery hogs galore.
What is sleep function and how do you enable it

Like myself and others have said, just use the device. You're comparing a device you used for a period of time to a device you just got just over 24 hours ago.
Those apps are considered battery hogs because they don't sleep. Also, Xperia devices have a sleep function implemented. They were the first ones to ever have such a robust background sleep function of Android devices.
The sleep function should be on automatically during setup but it could be turned off. Look under battery settings and it'll be there with the option to turn it off. I recommend keeping it on.

Yes i will give it a week and see if it settles. If not by hy note 8 and hello next phone. Lets see what time will show
Not sure where the setting do turn sleep on and off is, but the phone has sleeped (is that a word?) a bunch of apps. Battery is looking good so far today.
There was a video showing ba they life from a s8 a s8÷ note 8 and the late. And the note 8 lasted 2nd best.

I've disabled knox, security folder, bixby, ant radio all the t-mobile apps, several of the edge screens and a few others.
As others have pointed out, the device needs some days and several charging cycles to achieve a good performance, besides, and very important, in settings>device maintaince>battery, there are 2 groups of apps that you can choose, always sleeping apps and unmonitored apps, there you can control their behaviour

Yeah some of the Samsung apps and services being disabled will actually cause more drainage to occur.
