[Nexus 5X General] bblzd:
Your tests don't make sense because the SoC is not under heavy load when the screen is off, and when your screen is on your SoC is still working normally because you didn't disable every setting and go into airplane mode.

Also watching for 1% drain doesn't make sense either because there's no guaranteed way to say the phone drained exactly 1%, it may have already been at 99.5% and then dropped to 99% for example.

I actually know for a fact that in almost every phone the SoC consumes more power under load than a simple LCD. It's pretty easy to prove too by using power consumption measurements so I'll try and do some measurements for you for the 5x as I had done with my N5 to show the same thing.

If an LCD is the largest power consumer on a device that's a huge deal. The only recent device I know of that was the case is the Asus Zenfone 2 as Anandtech showed in their review.

Yes the Nexus 5 has PSR as confirmed by Anandtech. I'm assuming the 5x does as well since just about every device uses it now and those that don't have very noticeable consequences such as with the HTC M9.

Music barely uses the SoC. There's a thing called DSP audio tunneling that means the SoC does basically nothing for music playback, you should be able to get 40+ hours of music playback with everything else disabled and the screen off. Each song is only like 5MB so it's not like much network activity is happening during music streaming either. The Nexus 5 also has DSP tunneling and is rated for 50 hours of music playback (only achievable with everything else disabled).

But like I said this stuff is easily (very easily) proven with power measurements so there's really no point even arguing about it. I'd actually say it's common knowledge that an SoC under load will use the most power inside a device because the SoC is CPU, GPU, RAM, memory controller, mobile data, WiFi, etc. It's everything your device does.
[Nexus 5X General] jimv1983:
The 1% drain test does make sense if you start timing it as soon as the value changes and then stop the timer when the value change again. Example, you look at the phone and you see it says 88%. That could be 88.9% or it could be 88.2% so you wait and watch it change to 87% and start the timer then. Then you stop the timer when it hits 86%. That is a full 1%.

Turning on airplane mode wouldn't really make since in the screen on test since it wasn't in airplane mode when the screen was off. The power taken by being on a cell network should be pretty constant with the screen on or off.

Of course the SoC isn't under heave load when the screen is off. It wasn't under heavy load when the screen was on either. That is the point. The point of the test was too see how much faster the battery drained with the screen off and the phone idle(in Doze mode) vs the screen being on and the phone being idle(at least as much as it can be with the screen on).

Sure, the SoC was probably doing more when the screen was on compared to what it would with the screen off but enough to make the battery drain even close to 40x faster? No way. Some of that increased drain was from the SoC, of course but most of that increased drain was the screen. What else would explain that much of an increase in battery drain when the screen is on? Power used by RAM, memory controller, cell radios and wifi shouldn't be all that different with the screen on and the phone idle vs the screen off and if you are correct and the Nexus 5X does have PSR then the GPU was idle too. That just leaves the CPU which doesn't account for a 40x increase in battery drain while (mostly)idle. If it was the SoC then the phone must have been under EXTREME loan while it was supposed to be doing very little to get even close to making the battery drain 40x faster.

Yes, two plane rides yesterday both in airplane mode and solid green wifi bar for the entire day.

Can you guys also use this app "Power Tutor" to measure what the LCD is drawing (I don't know if it's estimated) at 0%, 50% and 100% brightness, with Adaptive Brightness "off"? I get the following for my Nexus 5X and LG G2 (which is roughly equivalent to the Nexus 5). However, an important note is that my "comfort level" brightness of ~35% on my 5X appears to be about the same level of luminosity as 60% brightness on my G2, so in fact during everyday use the 5X should be drawing less power than the G2. I also noted that the CPU power graph on the 5X maxed out at about 80 mW when scrolling through the results and switching back and forth from Chrome, while the G2 shot up to 200 mW.

Also, I did a series of Antutu runs last night side by side with the brightness at 100% for both devices and over 5 runs the 5X (2700 mAh battery) lost 11% while the G2 (3000 mAh battery, 1.5 years old) lost 19%. So by both of these measures the 5X is getting better battery life than the G2. I think it is difficult to feel out battery performance during the first few days because you are bound to tinker with your phone so much more :)

Nexus 5X:

0%: ~250 mW

35% (comfortable office use): ~450 mW

50%: ~600mW

100%: 900-1000 mW (measurement just about the 800mW line)

LG G2 (D800) CM12.1:

0%: ~300 mW

50%: ~600 mW

60% (comfortable office use): ~650 mW

100%: 900-1000 mW

This is from a period of about 1 day, 15 hours (39 hours) from 100 to 13%. Includes about an hour worth of listening to Spotify (mostly on LTE) and some listening to local files via Shuttle Music Player.

I charged it, and then went to bed with it at 97%. Woke up to a bunch of notifications and the LED blinking due to Light Flow, and the battery was at 89%. I am wondering if somehow doze got interrupted by my notifications, one of them was an SMS so I could see it having priority and stopping doze. Doze seems to have worked properly on the second night, as I don't appear to have lost much if any percentage of the battery. Still got some notifications too, but no SMS.

As you can see I only got 3 hours of SoT, mostly from not using the phone that much and listening to music with the screen off. It has usually been higher, especially if I've been using the phone a lot, but of course standby time is less.
[Nexus 5X General] bblzd:
Light flow has some issues with our device right now, causing Ambient Display to mess up and that might be why the device wasn't able to Doze properly as well. There should be an update incoming soon.

How do you find out the manufacturing date?

[Nexus 5X General] alwaysbelieve1:
I am coming from a Sony Xperia Z3c and have been going back and forth about sending my 5X back simply BECAUSE we were spoiled with our Sony phone. Nothing, and I mean nothing, has that phone beat with battery life. I actually was going to send it back until I tried to put the Concept MM rom on it and bricked my Z3c. LOL! So I am now a happy permanent owner of a new Nexus 5X. I will make it work and the rapid charging truly helps. When I am in the car, if I need to charge, then I will plug it in with my rapid charging car charger that I just bought off Amazon, and charge my phone to and from my destination. Even 10- 15 min charge can get us a few hours. So I know I will be happy, but if I have a day where I cannot be tethered to a charger if I am using a lot of juice, maybe at Six Flags or some outing (which is not a super frequent norm), then I have a Morphie I can bring. I think everyone is making a bigger issue out of sub-satisfactory battery life from what their expectations were. I haven't had to charge it yet in the car and have been getting around 4 hours SOT with some juice left to still carry me through. I am one who charges nightly so I always wake up with a fresh 100% in the morning. Next year, I am hoping Google gives us a big winner of a 5"-5.2" device and I will definitely be getting that for sure. I am also hoping Google figures out some more they can do to extend the battery life of the 5X with a firmware update too. Until then, I will enjoy my Nexus 5X and the streamlined Android OS without the bloat and with the regular updates to keep it fun.

Try a different browser than Chrome. I find mobile Chrome to be a total dog. If you do not mind a bit of hit on features, I recommend Lightning+.

https://f-droid.org/repository/browse/?fdfilter=lightning&fdid=acr.browser.lightning

You probably can find the same one at Play store. It is much more performant and less battery-consuming.
[Nexus 5X General] alwaysbelieve1:
You can also use Chrome Beta because it's much better in the bug that drains battery is gone.

[Nexus 5X General] fitchpuckman:
October mfr days here as well, and I've had several days with the same experience you describe. No help from a factory reset, or even safe mode before it. Not looking like manage date is any clear indicator since both Sept and Oct models seem impacted.

This. It's remarkable to see those dips with the display on. I also wonder if Google knew this and let it go because the doze feature works so well that they thought they could get away with it and still end up with okay battery runs? Regardless, it's frustrating. I'm traveling now, but will plan to RMA this on Monday.
[Nexus 5X General] Pilz:
The display could just be lower quality and use more power that's not reported accurately in the battery stats. O have a feeling it's a combination of that as another member mentioned and the processor since the phone gets really warm around the fingerprint scanner when the display is on
[Nexus 5X General] fitchpuckman:
I have wi-fi scanning on, but have always used it in part phones and never saw this kind of hit to battery performance, so unless it's newly buggy I'm not too concerned. I dialed Bluetooth scanning on day 1, so not a factor for me.

Fair. Oh, what a pain. It's a shame bc I like this phone a lot but dam if this isn't a disappointing mixed bag of complaints right out of the gate. If it were software, fine, I can handle that. But hardware scares me... I'm not willing to just sit around on a bad device with bad hardware that can't be fixed.

For example... I just woke up with 24% battery remaining (doze works great) after having to charge yesterday afternoon. I've been on these forums for the last ~12-15 mins and have seen my battery drop from 24% down to 6%. I don't care what my settings are at the moment, that's completely unacceptable from a basically any device.
[Nexus 5X General] donutman:
Android OS on mine seems to be draining the most. 3h 53ms keep awake! After my first couple charges, it was never this high. Now, not sure whats going on. Whats up with this?
[Nexus 5X General] Pilz:
I already did 1 RMA and the second one isn't any better. I'm returning it to Google because it can't get me through a day of my normal usage. My Nexus 6 can always get me though a day so this is disappointing. I bought another 6P (32gb) to take the 5X's place as my backup device will I wait on my now delayed 128gb 6P.
[Nexus 5X General] fitchpuckman:
Thanks, and fair. This isn't acceptable performance at all, and shame that it's happening on a second device. Hope you have better luck with the 6P... Just wish that wasn't so damn big or I'd be all over it.

Also, adding screenshot here per my prior comment on the rapid drop a few minutes ago (and because, right on queue, my phone died before I could finish editing the last post...)
[Nexus 5X General] Pilz:
I gave it a week to ensure it wasn't something I did one day but my battery life has been really bad no matter what I do. I'm sure the 6P will be better. I don't mind but phones after all I have Shamu the Nexus 6 :) I'll miss the little 5X because it was convenient with its tiny size but typing on its tiny display is tough coming from my 6.
[Nexus 5X General] paul_one:
right, I just received my phone about 20 minutes ago, and right now I'm starting to go through battery tests that are repeatable and should be able to be performed by EVERYONE.

I've charged the phone to 100%, disabled everything, not even set up an account on the phone, 50% brightness (dynamic off), location off, NFS/wifi off (no sim card inserted), not rooted/unlocked.

Currently I'm running the screen on with zero phone movement for 30 minutes, and I'll see what the usage pattern is.

I will then enable some features bit by bit and again see how the battery life is affected, and I will report back here.

Again, this is an attempt to actually do some tests which should be repeatable, so that is you repeat the same steps and get radically different results, then you have a defective unit.. If you have similar results but find you have battery issues when you use your phone normally it is probably a problem in a specific area, and so you should investigate that (again, a reason for these tests).

I would like to ask if someone who is getting really good battery usage - if they could (perhaps next week once the tests are done) do the same thing and confirm, that would be awesome. Ideally 2-3 devices doing the same thing so we get accurate results would be good.

Plus any feedback you guys want to feed me would be useful: for example, I don't see an option to disable wifi scanning when it's not connected or off.. Have they removed that option now?

---------- Post added at 03:19 PM ---------- Previous post was at 02:53 PM ----------

UPDATE: Everything disabled, screen on for first 30 minutes at 50%, and home screen showing: 3% battery used (what does that give us? ~14-15 hours SOT?).

I've got a few screenshots, and so I've just enabled wifi (still no account to sync with though), and we'll see how that changes things.

I don't know if I captured the screen when I looked into the battery graph in detail, but the network seemed to show used for the 30 minutes, even though I don't have a sim card and wifi was disabled (all wifi scanning seemed to be disabled apart from the 'show public networks' option... I think that may be the option I missed... oh well).

I got several screenshots of the option settings too.
[Nexus 5X General] fitchpuckman:
RMA Question...

I just did the RMA, didnt want to waste more time in the event that this really is hardware. to those of you who have RMA-ed b/c of battery problems....how long did it take for the new phone to arrive? I have until 11/15 to decide if I'm ultimately keeping the replacement or returning the phone for a refund, but hope to have at least a week to play with it...

---------- Post added at 10:36 AM ---------- Previous post was at 10:34 AM ----------

Are you referring to the option in Settings > Location > (overflow) > Scanning?
[Nexus 5X General] paul_one:
I did look in there and it's off by default (or so it seems) - unless it's disabled when you disable the location services.

I think I was actually after the wifi -> advanced -> notify me of public networks (not precise as it's off the top of my head).

The one that does wifi scanning and looks at network names etc. I've left it on by default, which was a mistake - but shouldn't screw things up hopefully.
[Nexus 5X General] lopri:
I ran GB battery test and the result is good. (~8 hrs.) I am guessing the test was mostly run on A53s while A57s were shut off. Display was on but dimmed, and LTE was on but WiFi was not.
[Nexus 5X General] paul_one:
Update: enabled Google sync, no difference on timing... I was going to set up my mobile network but I didn't realise the N5x had a micro/nano/whatever SIM, so I'm going to have to get another SIM card from my provider *sigh*.. Well that's no fun.

I'll do the test again with location rather quickly, but I doubt I'll see any difference - I would argue that the issues have been app based (ie, people are installing crap on their phones and expecting something other than crap out of the phone).
[Nexus 5X General] lopri:
[MENTION=3112165]paul_one[/MENTION]: What exactly is it you want to test? Leaving the phone idle for 30 minutes and see how much battery drains?
[Nexus 5X General] paul_one:
Basically the people saying battery is pants and drains quickly are reporting 2 hr screen on time etc. Some are even going as far as replacing their devices thinking there is something wrong with their hardware based on this.

I'm basically testing the base OS, and so far I haven't seen anything wrong with mine, and I've seen no sort of similar analysis from those complaining of low SOT, they simply show screenshots of GSAM battery monitor and claim the phone is bad.

Yes currently the test is just the home screen as it is first set up for 30 minutes (minus a few seconds). But I shall be moving into music playing, movies, etc soon.
[Nexus 5X General] lopri:
Well since my last post which was about 30 minutes ago my 5X'es battery went from 83% to 83%..
[Nexus 5X General] gerg004:
It's fine to compare, but the debate and wonder why some have 4 hours SOT and others get 2 is almost baffling.

Battery drain and everything that has to do with it varies from user to user. You could line up a million phones and a million people and you're going to have a million different results.

Sure there may be a defective unit here and there, but everyone runs different apps and uses the phone more / less than other people. Hence more / less battery drain.

Sorry, not here to rain on anyone's parade, and sure let's compare away, but this is Android 101.

Basically ideal situation: all WiFi, good signal.

Settings: adaptive brightness on, set as in the screenshot

High accuracy location, WiFi, data always on, everything always synced.

Disabled encryption.

Changed hispeed_freq to max frequency on each cluster and changed io scheduler to deadline.

I get about 30-45 mins less total sot with mixed WiFi/LTE. This device is capable of really good battery life.
[Nexus 5X General] 95Z28:
I find this phone is perfectly reasonable in the battery department, for myself I have been getting more than 4.5 SOT over close to 2 days for the past few charges (only had the phone 10 days). I have 2 gmail accounts always synching, location high accuracy on, set brightness manually to whatever is comfortable for my current surroundings, don't use WiFi, and have fairly strong LTE signal most of the places the majority of my time is spent. If I came from my Moto X 2014 with a smaller battery and ended up getting worse life I would absolutely be upset (and almost sent the phone back for being equal, but 2nd charge really improved life). So, yes. Battery life is dependant on user, but if you upgrade phones and find life is significantly shorter on the new phone I wouldn't blame that on user error because I imagine they are using the phone the same way they did the previous phone.

I shouldn't have to change usages patterns on a new phone to see equal or greater battery life unless the battery is smaller, or powering a bigger screen, ect... All things equal there do seem to be many valid complaints. Hopefully they are mostly software and get worked out, if they are hardware problems than hopefully anyone that RMAs gets better results.
[Nexus 5X General] zjsdlr2:
I had the same question after I requested the RMA and the rep assured me that the 15 day period would start over with the new device. Regardless, I selected ground shipping Thursday and it expected to be here on the following Wednesday. That will give me 4 days to evaluate even on the old 15 day period.
[Nexus 5X General] rydare:
Another day, this time from 100% → 16%. Less total time off battery (22 hours compared to 39 last time), but more SoT (4 hours compared to 3).

I'm going to uninstall Tinfoil for Facebook, since it somehow manages to suck more battery than Chrome despite being open for much less time. It appears to just be the mobile website anyways, so I'll just use Chrome from now on. Chrome's pinned to homescreen feature can even give me annoying notifications (Mom has posted a cat picture!) which I've turned off.

Still having some issues with Light Flow, sometimes it doesn't want to kick in and display the correct LED colour (just shows the default), and it seems to mess with ambient display. Hopefully it gets updated, the dev apparently has a 5X now and is aware that certain colour mixtures don't display correctly.

Really happy with Doze, went to sleep at 40% and woke up with 38%, almost a horizontal line during that time.
[Nexus 5X General] thesoldier:
Here's what I got after a couple cycles:

I was on WiFi about 70% of the time, I just forgot I had always scan enabled. I think overnight it went from 50% to 47% so definitely happy with that. Everything syncing, though location was off for most of the time. Adaptive brightness at about 40%. Quite happy coming from the S6.
[Nexus 5X General] lopri:
You are probably right about defects. Only way the battery drains that fast that I can think of is traveling a distance where network signals are sparse and the phone keeps trying to connect/stay connected. And maybe GPS running together.

IMO you should give Doze a chance before deploying Greenify. Doze is, in a sense, Greenify. It works like Greenify + optimized GCM behavior (Xperia phones have been capable of it for a while)

I think both Chrome and Chrome Beta are duds. They are slow and resource-heavy. It has been a while I used Chrome and I was frankly surprised at how bad it is when I tried it with the 5X. I usually use Opera and Lightning+ on non-Samsung phones, and Samsung browser on Galaxy devices. I can attest that they all perform better than Chrome.

Yes, you can see it in the 3rd screenshot I posted. Actually LTE was the only connection that I had open during the test. Everything else including WiFi was off. I was surprised to find it still running after 6 hours. The screen was dimly lit throughout the test.
[Nexus 5X General] Pilz:
Well I use the 5X in the exact same places I use my Nexus 6 and I have GPS high accuracy on both devices. The Nexus 6 manages 5hra at a minimum and I have the brightness at 30-40% with adaptive on. The 5X was always set at 0 brightness with adaptive on. There's clearly an issue with the 5X that hasent been addressed and is producible on different devices with different people. Some people appear to get lucky and have a good one but I'm not going to RMA until I get one of the better ones
[Nexus 5X General] AquilaDroid:
I only see a couple references to Gsam Battery Monitor here but none that say it's working. I'm not getting any stats (see screenshot). There are several posts on the N6P battery forum with the same issue.
[Nexus 5X General] alwaysbelieve1:
Is there any issue with keeping Chrome or Beta on the device or do they do something in the background that can effect battery or RAM? I like using Chrome because it syncs with my computer Chrome browser. That's the main reason.

When you are comparing browsers in what ways exactly are you deducing one performs better than the others?
[Nexus 5X General] briant1234:
Interesting, I'm not sure how you guys are getting 4 hrs 51 min SOT over 30 hrs of idle. I seem to be getting around 2 -2.5 hours recently, even though I hit four on the second day of using it. Should I be concerned? Running mostly LTE with some wifi, location on, scanning off
