I did a little experiment yesterday, and posted the result on Google+ Nexus community. I got 8 hours of SoT with 18% left. No crazy battery-saving apps or ROM. Data sync, Exchange mail, Gmail and Google Now were never turned off. GPS is in battery saving mode except when I went running.

I think there's a common myth about SoT. Longer SoT doesn't mean the phone stayed awake longer, or it did more jobs. It just means the screen stayed on for so long but the rest of the system might be resting. Anandtech said Nexus 5 has PSR which allows GPU to rest when the screen is displaying static content. So I figured in order to get great SoT, I need to increase the time the screen displays static frame.

This is a bit counter intuitive. If you do things on your phone fast, ie you wake it up in short periods and turn it off after a burst of finger swipes, you will not get those unbelievable SoT because whenever your screen is on the GPU is working hard refreshing the screen and the average power consumption during your SoT is high. However, if you do your stuff slow and leave it idling while the screen is on, your GPU actually enters low-power mode and reduce the average power consumption during SoT, thus greater SoT.

So here is what I did today with my Nexus 5, which I usually get a little less than 4-hour SoT. First I reduced the brightness by creating a customized profile with Velis Auto Brightness. It's not super dim as my office is reasonably well lit (the phone measured 57 lux, according to Velis Auto Brightness). I then bought a book to read on my phone and set the display timeout to 30 minutes. Whenever people came to talk to me I just laid the phone on my desk with the screen on, therefore during most of the SoT it's displaying static content. The book reading UI only allows pages flipping, which also reduces frame updates compared with line-by-line or paragraph-by-paragraph scrolling that I normally did. Apart from reading I also spent a little time on Facebook, Youtube, Feedly, SMS(Hangouts), ran 3 miles with RunKeeper and listened to some music. No phone calls today.

Lesson learned? First of all, don't be too obsessed with SoT. It's all related to how you use your phone. More SoT doesn't mean more jobs done by the phone. Those people who get great SoT probably just do stuffs slower or let their phones idle more. Second, flip pages, or scroll fast. It allows the PSR work its magic.

very interesting stuff. thanks!
[Nexus 5 General] pixi86:
That is bad

Great spec but poor battery performance, no mater who producer is...
[Nexus 5 General] Mindspin_311:
100% stock phone, I think this is pretty good. I usually average 3hrs SOT, so once Im not super giddy about having a new phone, Im sure total hours will improve.
[Nexus 5 General] dwang:
You got this exactly right. I find that i get ridiculously high SOT if all I'm doing is reading a book since it utilizes the PSR powering saving feature.

But if I'm doing anything that requires a lot of scrolling or screen refreshes, my battery life isn't that great.
[Nexus 5 General] rancur3p1c:
I'm surprised this PSR makes such a difference.

to take this a step further we could turn off animations and use a web browser that lets us use the volume keys to scroll up/down.

Do you run with Eco Mode and Snake Charmer? I use both and get 6-6.5hr on average.

to me, SOT matters the most, as it's what I have the phone for. Making calls is a bonus. Music listening is basically free. I have the phone for internet reading, email checking, and texting, all of which require SOT.
[Nexus 5 General] ejwu:
I never turned Eco Mode and Snake Charmer on. My FauxClock setting is exactly the same as the author's recommendation. No OC, UC or UV.

I'm surprised by the result like you. I could have even made it 10 hours of SoT had I not increased the brightness a little, because 2 hours into the experiment I had more than 80% left and at this rate I wouldn't be able to drain the battery before I got off work.

I'm not a light user. I normally get 4 hours of SoT on my Nexus 5. I bought a Note 3 (S800 model) a few weeks ago hoping to get better battery life, but instead I found I can easily kill it in less than 5 hours without playing any games. I then realized it's the way I used the phone killing the battery. I switched between these two phones quite often, and after this experiment I'm done with the Note 3.
[Nexus 5 General] OptimusVDarwin:
Just got home with 40% left

4.4.2 with Franco kernel r20
[Nexus 5 General] wirelessFREAK:
I got 4.4.2 since yesterday. My battery life was great... Not anymore.
[Nexus 5 General] dehsA:
Android OS has been eating away at my battery on some random days and I'm unable to figure out the exact cause. I would also notice the phone would heat up significantly more than normal.

Rebooting fixes the issue but sure, I could reboot the phone before leaving home every morning but that's not exactly how normal usage is supposed to be.

Has anyone figured out why exactly? My previous phone was the Note II and I never had such a problem with it.
[Nexus 5 General] colander:
Does anyone recommend undervolting? How much deos it really improves the battery life?

Confirmed, im sure not sure what causes this in the first place. The router/settings or phone/software? Right now im just riding along with my data plan. The drain is very low again, I guess I just use WiFi when its needed. :)

[Nexus 5 General] Whelan189:
really nice post, gives another twist to something we don't think about, some people just starre at their hompeages on lowest brightness and think its good as they got good sot,
[Nexus 5 General] whitedragonz83:
Last night again on Wi-Fi my battery was killed by Android OS. I think it is related to "travel times" in Giggle Now as it didn't occur Saturday to Sunday I believe. Also I am fairly certain it is linked to Google Search based on this "foreground" running app listed overnight.

Google Search ran 100% in the foreground when deep sleep should have occurred. As it is only on Wi-Fi and not LTE, seems like a very specific problem. Turning off Travel times and will check tomorrow night what happens.
[Nexus 5 General] whitedragonz83:
Since Google Search is my launcher this might be wrong. Seems launchers always show high foreground even during idle... I'll still test the commute thing.
[Nexus 5 General] xdp:
That's interesting indeed, shows you can't compare to other users online too much, even when comparing SOT. I wonder if you tried the G2 instead of the Note 3 if the situation would be similar.
[Nexus 5 General] dehsA:
Android OS has been at it again today for me. From 100% to 50%, I managed to get 1 hour 52 minutes of SOT.

At the time, Android OS was responsible for around 10% of my overall battery usage.

I then made a few video and voice calls using Hangouts as well as LINE during my drive home. That was when my phone started to heat up even after the calls ended.

Battery started to drain (as you can see from the big dip on the graph). In a matter of 40 minutes, the phone lost about 30% battery and Android OS's battery usage increased to 18%.

Once I got home and got onto my Wi-Fi, the draining stopped (although that might be because I haven't really turned the screen on since). :eek:
[Nexus 5 General] rodeo2:
If it persists, simply power off for a minute and reboot. Yours is still better, during first two days after I got my N5 Android OS was above Screen and I even thought of returning this sh*t back. Someone asked me to power off and reboot. Now I consistently get over 5-6 hrs sot.
[Nexus 5 General] dehsA:
Thing is, I've had this Android OS problem for two days in a row now. I would hate to have to constantly reboot my phone every time I sense something is draining my battery. :(
[Nexus 5 General] rodeo2:
No just once and that's it. It worked for me atleast. Have just rebooted once and never did Android OS go crazy again.
[Nexus 5 General] dehsA:
Yeah, I made sure to reboot before leaving the house this morning. Didn't exactly help.
[Nexus 5 General] whitedragonz83:
What does the keep awake show for Android OS?
[Nexus 5 General] dehsA:
Where do I check that exactly? I actually checked both WLD and BBS and I wasn't able to find anything that really stood out.

Would you say that using a smartwatch would result in better battery usage then? Since people would probably be checking their phone less.

My n5 battery is going up crazy fast, like 1% every 2/3 minutes :o have done a factory reset to solve wakelock but the drain is still prety big.

Sync,gps,mobile data is all off.

Is this a hardware problem?

[Nexus 5 General] ukemochi:
Battery Drain

Over the last week I have tried 4 different ROM's 1 of them being CM based, I have tried every kernel available out there and have followed authors instructions on how they would setup the phone to be battery friendly. Everyone but seems to have AMAZING results. One of the popular kernels is Faux123, I find it weird how I have tried the U and M version of his latest kernel and when I install his app, Eco Mode and that other one that sits below it will show up SOMETIMES but not always, quite irritating. I honestly have given up on altering the phone to get better batter, I see no difference from Stock.
[Nexus 5 General] whitedragonz83:
I'd try to do a full charge... Get the device to 100%.
[Nexus 5 General] kayone73:
I finally hit a sweet spot in battery life on the N5 after making some settings adjustments: Currently running latest version of Cataclysm rom with it's Smart Radio feature turned on, set selective wifi scanning when wifi is on, partially disabled location services restricting it to GPS only, turning it on as needed to mobile networks when using apps like yelp, and running faux kernel with a global undervolt of -50

This was an average use day mostly texting, a couple short calls, web browsing, a lot of music playing, both web streaming and off the phone memory, a few photos, didn't really play videos or games.

Could have easily broken 24h, maybe 25h if I wasn't monkeying around with the phone during it's last hr. The battery drain during idle is key. I took the phone off my charger fully charged around 1am while in bed and when i woke up for work around 6am, it only dropped to 98% which was pretty amazing for both wifi and mobile data radio being on. Even while at work with no working cell signal half the time, the custom rom smart radio feature kept my phone from needlessly hunting for signal half the time.

for a guy coming from Galaxy S2 who used to get 17 hrs of battery backup with only 1:30 hrs of on screen time .The battery life of Nexus 5 is just great !
[Nexus 5 General] muEcke*:
I get a great battery life with Purity ROM and Franco kernel, though I wouldn't call me an average user. I have almost everywhere wifi connection and thanks to my carrier a pretty good signal most of the time. I dimmed the screen a bit using lux because the auto-brightness is much too bright for me. I also use llama to turn off wifi whenever I leave a place where I have wifi and turn on 3G and vice versa.
[Nexus 5 General] adey64:
on edge all the time? ..it would explain
[Nexus 5 General] pgptheoriginal:
Here's mine: stock 4.4.2 ROM and kernel, always on 3G network, WiFi off (I turned it on just a couple of times for downloads), BT off, 10% brightness during night (otherwise auto), GNow and location history on, ART.

I used my phone mainly to check/write messages, use Tapatalk, read news with Currents, and browse the web with Chrome. Took about 20 photos, maybe I did something else I can't remember. No phone calls.

That's an average result for a modern phone, with 4 hours SoT in a full charge. I'm rather happy with the battery life of my N5 :)
[Nexus 5 General] dazz87:
Light use. Texting and surfing the net. 45 mins of listening to music. 30 minutes of BT. Faux kernel and cataclysm. 7+ SOT
[Nexus 5 General] iOSecure:
wow... before you applied the kernel and tweaks what was your screen on time?
[Nexus 5 General] dazz87:
Maybe about 4 hours at best. Was using Franco kernel with the same rom and the best was around 5hrs and 50 minutes and that was probably the best I've reach on Franco. Using Faux for only the past 3 days. Hopefully it will get better!

[Nexus 5 General] Dan1909:
What you say is true, but has nothing to do with what I was saying. Of course the phone will have some system to stop overcharging, but that's not something the user ever deals with.

We were talking about the procedure for the first charge of the phone, which is simply that there isn't any need (any more) to charge it for a specific time. Your point proves that in fact, by saying that the phone will automatically stop charging at 100%, so an 8 hour charge is completely irrelevant.

And yes, heat is a factor in battery degradation, but it's one that through normal use of the phone can be ignored. If you're not doing something strange with the phone, then it will be within the operating parameters it's designed for.

[Nexus 5 General] prawnguevara:
Sorry, yes.
[Nexus 5 General] dimgl:
I think everyone needs to chill out. I have been using my Nexus 5 and the battery life is seriously not bad at all. It's like a normal phone: it lasts you for the day, if you hammer it the battery will die quickly.

The people who complain are those who want insane screen on times of eight hours, which is simply ridiculous. If you want such good battery life, wait for kernels and custom ROMs to flash on your Nexus 5 or just switch or wait for a phone with a bigger battery (LG G2, Note 3).

I don't have any statistics yet but this phone has been more than enough for my usage (and I use my phone pretty heavily) so please don't let this thread discourage you from buying a Nexus 5. * Edit
[Nexus 5 General] twolfekc:
I am not pleased with battery life at all. Hope that a few more cycles and it will at least as good as my old nexus 4.
[Nexus 5 General] zerogun:
Not to hijack the thread... but with Stock ROM on the Note II I would get 4-5 hours screen time. I'm on Carbon right now and am getting 3-4 hours screen time. Love 4.3, so I'm not going back.....

It's a moot point since I plan on switching over to the Nexus 5 and selling the Note II anyways.
[Nexus 5 General] hamad138:
No just no it will only decrease now
[Nexus 5 General] cbowens:
I'm kind of surprised that so many people have these opinions on the battery life already, when at most you could have only had it for what, 3 days (for the lucky few that picked it up on Friday in Europe). Most people probably have had this phone for less than 24 hours. I'm not gonna get into the debate I saw going on about whether these batteries need a few cycles to reach peak charge capacity, but I will say that maybe you should give it a few days of consistent use before you make a judgement one way or the other.

---------- Post added at 07:06 PM ---------- Previous post was at 07:00 PM ----------

From what I remember reading, the snapdragon app mainly just adjusts sync intervals of the various apps that use your connections and adjust connection settings. It basically tries to limit things as much as possible without, theoretically, being noticeable. In the end though, you have to remember that you can't get something from nothing; the app saves power by sacrificing some level of connectivity. Whether you notice, or whether its worth it, will vary from person to person.
[Nexus 5 General] coolchris909:
my $.02

I don't have mine in hand yet, but a couple of things I consider important when thinking about battery:

1. A battery that lasts all day is subjective... Can I use golf logix an entire round, lounge for a while, leave and not have to worry about not having power ? Or how about nights I catch a game and drinks after work... am I @ 10% when I get home or do I have a decent cushion for after hours if I need it. If I stream an entire movie on a car ride, am I down to 50% ?

2. How long does it take to charge ? Can I throw it on a charger and get a quick 50% in 30 minutes or so ? All of my chargers are 2A to minimize charging time for all of my devices.

3. Will I regret it if I don't get a bigger battery ? How often do I actually need a big battery... I'm a heavy GPS / screen on time user...camping, hiking, fishing & lots of outdoor location.

4. I am always searching for signal and so polling can be an issue for me at times.

Yes yes, I am always near a charger, but do I always want to have to have one. Quick charging helps, but my benchmark is the 30 minute charge....
[Nexus 5 General] brittonberkan:
Here's my two cents on the battery: It's not good. But neither was battery life on my nexus 4 when i got it. I remember getting 2:30 hours of screen-on time out of it with the stock rom at the beginning. Whatever happened in the meantime made battery life so much better on the Nexus 4 that i actually ended up being pretty happy with it (4 hours of screen-on time? no problem)

Let's just hope that the same thing will happen to the nexus 5. I don't know what it was, probably software optimizations and battery calibration.

Oh, and one thing: The screen is too bright on auto brightness IMO, that's also a battery killer if you ask me. Anyone else experiencing this?
[Nexus 5 General] cbowens:
Yeah, I noticed the auto brightness being pretty aggressive as well, and I've read reports elsewhere of similar observations, so its likely not just us.
[Nexus 5 General] NatTheCat:
From a measly 2300mah its doing pretty good. Auto brightness is very strong IMO and running Bluetooth all the time is unnecessary in most scenarios. It may get better with updates and kernels but let's face it, battery tech is in need of a revamp in phone manufacturing.
[Nexus 5 General] jodvova:
Does anyone know how Nexus 5's battery life compares to Galaxy S4 GE ?
[Nexus 5 General] Matrix_19:

21hours with 1h48 screen time
[Nexus 5 General] Zorachus:
I used to have a Note 2, with a TW ROM, I was getting 6.5h to 7h On Screen time no problem. Sometimes close to 8h.

If you only got 4h you had a defective phone with hardware issues, no way the Note 2 only does 4 hours on screen time.

Now my Nexus 4, yeah that phone blew chunks on battery life, maybe 4 hours on screen time on a good day, which is not enough to get through a busy workday. My S4 gets me 5.5h to 6h On Screen time. On Sunday I got 6h 40m On Screen time with my S4, after 19 hours unplugged battery alert sent off showing 19%.

IMO for an end of 2013 flagship the battery life is sub average. Don't tell me that it is cheaper because I do not see a manufacturing cost increase bigger than 5 $ between 2300 and 3000.

To me LG did not allow Google to make the N5 as a near perfect device to protect the G2. What a pity! :(
