SNS battery dead in 6 hrs or less. - Nexus S General

I am posting for a friend that has a SNS. The couple of days he has been draining the battery in about 6 hrs. I looked at the battery usage and it said that the display was at 60% and the graph shows a constant fail of power. I checked and he has the screen set to auto brightness and the screen times out at one minute. The only other thing that I cna think of is that he has poor cell coverage but we are using wifi in that location which his phone is connected to. I understand that poor cell coverage causes power drains but with the major of his data going through the wifi one would think that the cell power drain would be minuscule. Thanks in advance.

It depends on how weak. Data is not going to route over the cellular network, but it will try to maintain a connection for things like calls. Thus the phone will attempt to maintain a connection to the tower unless airplane mode is enabled or the cellular radio is otherwise disabled.
If the signal is really weak then the gain is going to be automatically adjusted to try to boost the signal - this is going to cause an increase in power used, sometimes substantially. If you spend most of the day in this situation then you don't have many options currently if you want to receive calls on the phone (you could look at a SIP solution).
If you don't care about receiving calls just turn on airplane mode and then toggle wifi on.

You need to provide screen on time and awake time. If he just got the phone and is using it a lot.... well then six hours is not bad for an android phone.

Not really. Maybe 6 hours continuous use, something like 3 hours display at 20-50% and 3 hours talk time; that would be normal. But 6 hours low-medium use points out that something is indeed wrong.

But like I said we don't know if it was normal or heavy use without screen on time and awake time.

60% display means the phone was on and actively used for over 3 hours. That's a fair bit but isn't too much really, but it depends on what else is running durng that time. As mentioned, awake time is also important because it means the phone is actively working at something even though the screen is off. He may have a rogue app that he installed sucking power. Or simply leaving the web browser on a webpage with a regular refresh cycle will cause the browser to continue to run in the background keeping the phone awake while the screen is off. I've gotten in the habit of going back to the google home page when I'm done browsing to make sure it's on a "dead" page.
Anywho, more details are needed to figure it out. Just saying it's only using 60% display isn't enough to find out why the phone only lasts 6 hours. Mine lasts between 24-48 hours depending on usage from heavy to moderate. With light usage I figure the battery would last 3-4 days, but I'm not that light of a user and I generally top up every night anyway as it's better to top up a Li-Ion battery than let it run down all the time.

Huh???
When it says "What's been using the battery" and it says "Display........ 60%"
that just means that the display is responsible of 60% of the battery drain that has occurred since last boot.
For example, if you were at 100%, then turned your phone on for 5 minutes and scrolled back and forth on homescreens, lets say your batter went down to 95%. Well, if 2.5% of that 5% loss is from display, and 2.5% is from Android System, then when you check the battery screen it's going to say "What's been using the batter?"....... Display - 50%; Android system - 50%.
If you did the same thing for 4 hours, and the battery drained down to 20%, you might still see...... Display 50%, Android system - 50%.
In other words, the % has nothing to do with how long the phone has been on.

also if screen on time is 3 to 4 hours, yes the battery will be very low by then.

Thank you all for the advice. As I said this is my friends phone. i don't see him using it a lot we are both programmers so we use a computer for most everything, and we have both our phones on wifi because of the terrible cell signal. I will ask him to try and keep up with everything he does to see his use patterns to see how much he is really using the phone. I will post later on what apps are running and his amount of use. The main reason I am not sure is because this has just started happening with in the last week. We have been in the same location for 6 months and it has just now become a problem.

Hmm...ok that kinda helps, but it doesn't really explain what's happening when it uses that setting. I know that PRL means preferred roaming list, and GSM Auto means it selects automatically, but how it selects and why it uses less battery is what I want to know.

What battery issues?

Before getting this phone I did my fair share of research on it and every review said the same thing, super phone...terrible battery. Now I never owned a touch screen phone before this so I had no idea what the desire, Samsung or iphone battery life's were like and all these reviews were causing me some concern and led me to believe that my phone would be dying over 9 hours or so due to lack of power.
Now having had my desire HD a few days I just want to say wow what was all the fuss about? I get a full 24 hours use out of a full charge without taking any precautions to save the battery. When I'm at home I leave my wifi on continuously, it was on for a good 14 hours yesterday. When I go out I switch over to 3g and turn wifi off...only used this for an hour or too since I wasn't out much. And remember I only got this phone a few days ago...so the usage has been pretty heavy as I fiddle around with it, doing some web browsing, have all my accounts and widgets syncing, play a few games, making some calls. On the first day I got it yes I drained the battery in 9 hours but that was super heavy use...i.e. I didn't put it down once in those 9 house.
This phone easily makes it through 24 hours with perfectly normal use without having to worry about the power levels. Great phone and I love my first android to bits!
I'm glad to hear some positive things about the battery as Verizon has the incredible HD coming I plan to purchase when they get LTE.One thing though that you may not know is your wifi wasn't running continuos, it shuts off when your screen shuts off and comes back on when you turn it back on unless you fool with the wifi settings and tell it "never" turn off. But overall I'm glad to hear that

Does it drop the wifi when the screen is off by default? Not so on my standard desire as far as I am aware - unless this is something new in the HD rom?
Good to hear the battery is lasting well according to the op. Little 3g use though it seems and it is this that cains my desire.
There seem to be some mixed opinions on the battery life. I use mine quite heavily and have to admit that the battery life isnt the best that i've had but i'm happy with it as it lasts me what i consider a 'normal' day, ie, take it off charge at 7.45AM and after a days use (calls, internet and syncing all day every 15 minutes, music, wifi and bluetooth left on) and it gets me home for around 7PM with a bit of charge left. That for me is a normal day, if I know i'm doing anything else i'll put it on charge in the office/car. If I need satnav i'll always use a charger anyway.
So... For me it's OK, but not good, could have done with a higher capacity battery.
No Battery Issues At All
I received my HTC Desire HD 2 days back and have no worries about the battery at all.
On first charge it lasted over 12 hours and I was using it VERY heavily. I'm currently on my second charge now and after 24 hours of medium to high usage, I have 40% remaining.
I always have my syncs set to update/refresh as often as possible, so mail is every 5 mins, weather every hour, facebook every hour, have Google and HTC Sense syncing too. I've also left my wireless setting to stay connected even when the phone is on standby and am getting this performance out of the battery.
So it just leads me to believe that anyone saying this phone's battery is poor must not have used a smartphone before.
And with regards to the WiFi settings, you have 3 options. Go to Settings, Wireless & networks, Wi-Fi Settings, press Menu then select Advanced. It's the Wi-Fi Sleep Policy you want to take a look at. Like I said, you have 3 options; After 15 min, Never when plugged in and Never. Someone said you can have it turn off whenever you go into standby, this is not entirely accurate. With the After 15 min option, it turns off WiFi if you are in standby for 15 mins. With Never when plugged in it's the 15 min rule again except when plugged in. With Never, it just constantly stays on.
By default it is set to Never. I've left it as this to test how much it eats up the battery and I have no issues.
P.S. It's always best to do a full charge/recharge when you have a new battery to get it to use the full capacity. Charge the phone fully and use it until it dies. Charge it fully again, not taking it off charge until done, then let it die. Do this a few times and you should see the capacity go up. After this you can charge however you like although after time (months), you may see the capacity seem to come down, in which case do this again a few times and you should be good to go.
The battery on my HTC Hero came down to lasting 12 hours after 9 months. Did this a few times and not it lasts about 36 hours.
Yes I have my wifi set to never switch off...it still does all its sync'ing and mail retrieving whilst in stand by mode. I even went into the battery usage last night before I charged it up again and it had been running on the battery for 24 hours and 15 minutes and I checked the wifi usage and it said it had been in use for 13-14 hours and it had only used a small amount of power (less than 12% if I remember correctly)
i agree..
Its just as good if not better then the other smartphones i had.
battery is good.
just keep the brightness at 30%
2 days since I charged my Desire HD and it's at 40%, much better.
Wifi to turn off after 15 mins in standby, brightness at 100%, mobile data is turned off unless I'm out of the house (in that case, I turn off wifi) and that's with Buzz's overclocked 1.5GHz kernel.
I think any time mobile data is turned off the battery life is going to sky rocket!
Fortunately, by using ultimate juice you can automate this - using wifi when available and mobile data at other times without having to manually switch. Better still, this leaves both off unless the screen is active. Made a hell of a difference to my Desire.
i keep mobile data off (only turn it on when i'm out of range of a usable wi-fi)
screen brightness is at 30%
I use "Set CPU" to lower the CPU to 256Mhz when the screen is off.
I get all my mail via gmail.
there's also a hidden app (can't remember how to start it but it's a *# code)
you cna use that to set what type of mobile network it looks for (I've defaulted to use GSM but use 3G when required).
This keeps the mobile form constantly looking for a 3G signal when youre in a bad signal area (or in the bottom of your bag!) But this won't affect data, only voice calls.
The constant looking for networks is one of the biggest drains on a mobiles battery after the screen/light.

I've had about 8 HTC phones in the past few years and I've always been very pleased. Lime many others before buying the DHD I did my research and got a little worried about battery life. I wish people would just post opinions for the sake of it (especially in the first day or two of use) because it's very misleading. After having the DHD for a while now I can honestly say that I'm really impressed with it especially with the battery life.
I previously owned the HTC Desire and at first had much worse battery than the DHD mainly because of the AMOLED screen and it needed some tweaking after root. At the end I was getting at 3 days of battery with all the common daily abuse.
With the DHD I got 2 days right form the start and you know what it's like in the first few days. You pull it out for no reason, play with it, show it to everybody try everything and even so it lasted 2 days. Now that I'm back to just the normal use/abuse I get 3 days with no root, no custom rom or other tweaks.
SO anyone doubting the DHD battery life, FEAR NOT it's a great device!!!
G
I agree great device but could you please put your battery up on ebay for auction as I think you've got an amazing battery and could make Fair few hundred pound from it or even send to htc so they can use as prototype and make all of us replacements that lasts days like yours.
I personally think the battery sucks but with the hardware you carnt expect much more from the battery thy choose for this device.

My battery is about a week old. It wont make it through a working day (8 hours) if i use the phone for anything. It wont even last a morning (2 hours) if I'm making calls and browsing net more intensively.

Not true. I've had several smart phones, and I can't last a full day doing the same things that I did with my Hero. I don't have anything syncing regularly either. Weather every 3 hours is about it.

3 days of use? By my reckoning the main dictator of battery life is screen on time. I find that I get 3 to 4 hours of screen on usage time out of a charge. This would equate to an hour a day to last for 3 days. Unfortunately I use my phone a lot more than that.
I'm not doubting other people's opinions, but I'm seriously starting to think that I got a dud battery or something.

Some interesting stuff there, not sure how it will help me if at all but I guess I will have to experiment...
I have HTC's since it came from QTEK.. I had 5 HTC before Desire HD.
Before this I had a HD2 (leo), and matching the most options possible between them, this is the faster draining phone that I had after HTC diamond.
Actually I've always thought that the HD2 due to the screen size had a very good battery.
I've been using desire HD a LOT since it's the first android that I had put my hands on my own, so I can be due to that, but most of the time I getting like 5hours or less from it which is getting me frustrated for the first time. Also there is a problem with this model, they probably won't be able to do a oficial expanded battery with this type of battery slot, due to the configuration.
However, I'll try to avoid touch it too much than the "normal" and see how it goes.. But I'm pretty sure that it's way faster draining than my older HD2.
BTW, I'm using "GSM auto (PRL)"

SyndicateROM Frozen (EB13) - Battery Life Thread

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.
Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.
I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.
I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours
With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.
1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,
I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.

i was at 55% at about 5pm yesterday after 10+ hours of battery usage, 1.5hrs of screen, and probably 2 hours of LTE (the rest wifi). i use juice defender so when the screen is off it generally cuts data signals for me. well from 5pm to 9pm my battery went from 55% to 1% with maybe less than 30 minutes of usage (all on LTE though). i looked and no unwanted programs were running in the background.
i charged it overnight, got up and after an hour this morning of ALL standby (seriously the screen was on 3m), i went from 100% to 87%. that would mean on 100% standby the phone would have died within 8 hours, which is definitely not right or even similar to previous battery usage for me.
i restarted my phone, recharged, and so far it has been on for 40 minutes and the battery is at 99% with 2m of screen time, which makes a lot more sense. so have you ever experienced something like this where an android OS restart helps your battery, or does it sound like i might have a bad battery?

Install Carat, it will tell you exactly what is draining your battery. I'm guessing something something is syncing in the backgruond and killing your battery.

Lots of people are having an issue similar to this with ATT. Is your ATT?
i am in fact ATT. sorry i haven't seen the other posts about it, have they broken through to figure out the root of the problem? any link to a thread about this? it's very, very odd. 8 hours of battery life is no good, too.

I seem to get it when I am in a poor LTE coverage area, which includes one of my offices. It is strange. "Cell Standby" will usually have the largest battery usage in your settings. My temporary fix is to turn off "mobile data" from the toggle in notifications, especially if you have wifi where you are. You can usually tell when the battery is being drained b/c your phone will stay warm even with no apps running and the screen off. The only other thing that seems to help is restarting it every day or so. When I don't have this problem, the battery life on this phone is amazing, so I don't think it's a bad battery. If you find out a better solution, please let me know!
I'm assuming you get off work at 5 and use the phone more. If so, turn off juice defender when you leave work. Since juice defender turns off your signal, you have to reconnect every time you use the phone. That kills battery more than anything

I would agree with your deduction. Cell standby is a battery hog. I use Wifi when I am at work and home. and HSPA+ everywhere in between. (No LTE in NH)

Doesnt that defeat the purpose of having JD? Has anyone shown than JD uses more battery than not having it at all?
Fyi cell standby doesnt actually use as much battery as it reports, its just incorrectly displayed on the battery meter. Hopefully there will be an update to fix it eventually. Google it if you want to fix it manually.

Cell standby is just a reporting bug. It is not actually draining your phone as much as it shows.
There are two separate problems. There is the problem on the international S3's where it is reporting cell standby incorrectly. There is another problem with some of the ATT S3's where they are continually connecting or re-connecting to the network where they have a poor LTE signal. This is actually using the battery. You can feel the heat from your phone when you have no apps open and it is normally cool to the touch. The only solution I have found so far is to turn off mobile data, and the phone will cool down again and stop draining battery.

Right. It's just cosmetic.
I don't have LTE in my area and my battery life is okay. I use wifi at my house and at work. I just think it could be better, but i am used to my dinc with my custom rom and kernel. Amazing battery life. I can't wait until we get some sweet roms and kernels for the S3. So far i am super impressed with the phone.

i think you guys are right. the only thing that fixed my problem was restarting, which obviously also turned off/on the mobile data. how would you do that normally? just hit airplane mode and then turn it back on?

This isn't a problem that too many people are having, but there are enough that it must be a bug, at least for ATT. There is a toggle in your notifications that will turn off mobile data. I don't think it is enough to just turn it off and back on. If you are in an area with bad reception, you have to leave it off or the draining continues. If you find something else that works, please share with us.

I'm also seeing this issue; battery gets hot and drains quick in sleep.
I'm running stock, and only rooted.
I do notice when checking my battery that "Android System" is taking up the majority of my battery, by a considerable amount. Is anyone else who is experiencing the drain issue also seeing this under their battery reporting menu?

Battery Life Worry/Question

My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!
Same here. On all my other Android phones Screen is the top user.
U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?
Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?

Doze Performance

So Doze is supposed to minimize battery drain to almost nothing overnight or when the phone is not in use for a long time. How many people have actually experienced that? I'm not sure what to think, I lose about 1% per hour consistently overnight. That's without greenify or other battery saver methods. But it still seems excessive to me for such a hyped feature. I wonder if future hacks will be able to turn doze on in 1/2 hour instead of 1 hour. What have your experiences been?
1% per hour is pretty good. That means your phone would stay on for up to 100hrs which is more than 5 days. Are you complaining about that?

Doze only dozes applications from waking up the phone at their will, but still does periodic wakes. It will only make a big difference really if you had a misbehaving app in the first place.
Don't forget that even in the best case that Doze stops all activity from apps, you are still using power connected to the cell and or Wi-Fi, plus power to refresh the memory and other peripheral chips, so 1% an hour could be considered quite good.
Try putting the phone into flight mode over night and see if that 1% drain an hour goes, if all is well you should get around 1 or 2% power loss in 8 hours.
The other think to note is apps can bypass Doze and schedule wakeups regardless, this needs an update to the app for Marshmellow. So if you had an app that wanted to wake the phone every 10 minutes to download the latest adverts, it will stop under Marshmellow when Doze kicks in, but they could update their app to use a different API call and go back to waking the device every 10 minutes bypassing Doze. I strongly suspect that the Google Play store will start recognizing this API call and may start warning about apps that are battery drains, so the user can make a better decision, otherwise Doze will have a short term benefit as apps work around it.
Regards
Phil
Doze is working really well for me. Battery drain overnight seems to almost be non existent. I went to bed with 51% battery life on my phone. I woke up roughly 7 hours later and it was still at 51%.

that was a great explanation, also I do think 1% per hour is bad since like someone already stated that I've had phones that would drain about that without marshmallow. Also those other people who replied I would really like to know how you get such little battery drain, do you guys have a lot of apps installed? I unplugged today around 5 am and woke up around 10 am with 95%. I have about 60 apps and 3 email accounts (1 yahoo which is set to sync manually).
Personally I am trying to sort my battery issues with this phone as some are getting great battery life (5 hours sot with over 24 hours off charge) while others are barely hitting 3 hours like me. Also I would think doze would be better than what I am experiencing.
How long have you had the phone for? AFAIK it can take a few days for Doze to "learn" how to optimize (reduce) battery drain. You may find it gets better over the course of a week or so. If you check the "detailed" battery stats (click the first battery graph) you should see little to no "awake" time overnight when you'd expect Doze to kick in - e.g see this link as an example: https://drive.google.com/open?id=1wjguaIIcGgUZn7w-KXnY3MJ0qTK0rUCWiA
Otherwise try as @PhilipL suggested and run in aeroplane mode overnight.
Doze is working as advertised here. On my 5x and my N5 as well.

It could be your location and the cell signal you are receiving, sometimes even if you have a good signal you still might be evenly served by 2 or 3 masts and the phone keeps swapping between them, if you don't have too good a cell signal, the phone will be using more power during standby. The only way to tell for sure is to put the phone into flight mode overnight.
One thing to note, you will only get the maximum screen on time if you use your phone a lot, i.e. all the screen on time is used during a 12 hour day after a full charge. If you are only using say 30 minutes one day, 20 minutes the next and so on, your total on screen time achieved will be less than many are saying they get, this is because more power is spent over time on background tasks and syncing, leaving less for actual on screen time. My previous Nexus 5 for example, sometimes I would go 4 days without needing to charge it, but my actual on screen time was only an hour or so.
Perhaps crudely speaking, 1 day of very light usage may see enough battery power expended on back ground tasks to see 1 hour sacrificed of on screen time.
Usually it doesn't matter how many apps you have installed, that in itself doesn't use any battery, of course if those apps are constantly pinging back home to some server, then that is how power is used. Doze will be helping with those apps over night and other quiet periods.

Thats the thing I get about 2.5 hours sot in about 12-14 hours and have to recharge before the night is over. Of course quick charge helps but I really don't want to rely on something like that. Also I'm wondering if wifi calling on will help with battery or will it be like the iphone where it'll just drain more battery? Gonna have to play with it and see what I can improve on. Also noticed that chrome has been using about 15-25% battery on any given day. I do use it as my main browser but that still seems excessive so may try a different chrome iteration if it keeps up.
Thank you to everyone that has helped and hopefully this can be a come all thread for people with questions about or problems with Doze.

Also I'm wondering if wifi calling on will help with battery or will it be like the iphone where it'll just drain more battery? Gonna have to play with it and see what I can improve on. Also noticed that chrome has been using about 15-25% battery on any given day. I do use it as my main browser but that still seems excessive so may try a different chrome iteration if it keeps up.
Thank you to everyone that has helped and hopefully this can be a come all thread for people with questions about or problems with Doze.

What brightness setting, as that can make quite a difference?

Adaptive brightness less than 50%
I'm getting 3 to 4% drain during 7 hours overnight, working well for me.

Hi
Did a test last night, charged the phone to 100%, put it into flight mode and went to bed, checked it this morning and still at 100%.

Now you need to find what is draining your battery overnight when not in Flight mode. I suspect you will find either Google Services or Google Play services not releasing the modem or something similar.
When I installed Cerebus it asked to turn off battery optimization. My guess is that is Doze could be wrong though. It was the only app that asked. So far battery life is better then the N6 that I had a Amplify running on.

That is pretty bad if Doze is on given that 1%/hr is a widely accepted standard pre-marshmallow

Might be a standard if everything worked perfectly, which I have yet to see. With this new architecture, you are guaranteed it. I love it.
I lost about 1% in 3 hours last night with WiFi calling on. Maybe it has to do with poor coverage. Last night I did end up with 3.5 hours sot which I think was my highest. So in the past few days I have factory reset and turned on WiFi calling.
Now I need to optimize my browser usage, chrome was talking more than screen was ~20%. Using #nochromo now and not much better.
Battery went from 66 to 64% last night in 8 hours.. #dozeisdope
