All,
In case you haven't noticed, the battery life of the Nitro HD is kinda bad... Then, when you add ICS into the mix, it gets worse.
When i first flashed the Leaked ICS ROM, I noticed that I was only getting about 8 to 9 hours of battery life with very light use. So, I endeavored to find a way to extend that time without buying an expensive extended battery.
Here are my findings:
GPS
Settings > Location Services
Now we all like the convenience of being able to pull out our phone and find the nearest gas station or fine dining experience. But when you think about it, in our day to day lives, we don't need directions that much.
GPS and Location Services are huge data and energy hogs. If you have ever seen how much can go on in the background when it comes to Location Services, you would cringe. So, set up your GPS like the screenshot below and you will see a little battery life improvement and data usage go down.
Display Brightness
Settings > Display > Brightness
On my Nitro, the display uses up the most energy by far. So, it only makes sense to lower the brightness a bit to save power.
Developer Options
Settings > Developer Options
The Nitro has a powerful 1.5GHz CPU which uses a ton of energy when in heavy use. Some of you might say, "But Matt, I don't use that many apps that need the CPU." Well, it's not that you use them. It's that the ones you have used are likely still running. For example, even though I always use the 'Exit' menu item in Slacker Radio, it will always show up as a running process in Task Manager.
In the Developer Options, there are a few useful ways to fix this problem.
First, check the box next to 'Don't keep activities'. This will cause whatever app you are using to stop completely as soon as it is not on the screen anymore. This is useful if you have the habit of using the 'Home' button when you are done with apps.
Next, set the 'Background process limit' to something other than the standard limit. I have mine set to 4 processes. This will keep processes that are not tied to any specific app in check.
If you use a lot of apps and games that have to render video, it might be a good idea to check the 'Force GPU rendering' box. This will force apps such as games to use the slightly less powerful GPU in the Nitro for video. Thus letting your CPU relax a bit. I have also noticed that heat doesn't build up as much with this box checked.
Lastly, if you want to know about more of the processes that hang in the background that may cause performance issues, you can check the 'Show all ANRs' box. Personally, I found it annoying.
Power Saver
Settings > Power Saver
I was really excited for this feature but also very skeptical. But, I gave it a try anyway. What this feature does is when your battery level gets to a certain percent that you choose, it will turn off power consuming features and change some settings to use less power. I have mine set to engage at 20% battery life.
The tips I have seen say to check every box. But, because of my profession, I have to have 'Auto-sync' left on for emails and such.
With the settings below, I usually see the last 20% of battery last about 4 to 5 hours of medium use.
CPU Clock
*Requires Root*
Unlike all the tips above, this one will require you to root your Nitro.
As I said before, the 1.5GHz CPU uses a ton of power. When you think about it, unless you are playing games all the time or doing some kind of complex calculation as part of your Quantum Physics experiment on you phone, you really don't need all that power. So, what I did was underclocked the CPU to 1GHZ. This gives me the power I need to do what I do but with more efficient energy consumption.
I used SetCPU for this but there are a few other choices out there that do the job just as good.
As you can see from the screenshot below, I have set the max frequency to 1026MHz and the min frequency to 384MHz (I have since set min to 192MHz). I set the governor to 'conservative' based on this post: LINK. But, I think that any of them will help in different ways.
If you are curious, I'm also inserting a screenshot of my benchmarks after the underclock.
CPU Sleep (Suggested by rani9990)
*Requires Root*
XDA user rani9990 suggested an app called CPU Sleeper that, essentially, puts additional cores into an offline mode while the screen is off.
I can see how this would be advantageous because when your phone is in sleep mode, it really doesn't need all that extra power.
I have had it on my phone since i got up this morning and have noticed a significant jump in battery life already.
Results
Before these tips, I was getting about 8 to 9 hours of medium use on a charge.
After, I get roughly 15 to 20 hours of medium use. (It varies from day to day but hovers between 15 and 20.)
If anybody has any other tips, please let me know so I can add them to the list.
You should also tell people to get CPU sleeper (root) saves tons of battery life for me.
Also, disabling haptic feedback saves battery.

! kick ass post!! well-done. fun read too.
thanks!!1
Sadly, battery life on this phone really sucks even with the optimizations. having compared both, I can say that the Nitro HD with optimizations and 3800 mAh Hyperion battery gets about the same battery life as a Galaxy Nexus on the stock ROM and stock battery.

Perhaps check your running processes. With these tweaks in place, I unplugged my Nitro at 7:45is this morning and right now, at 2:15pm, I have 79% battery left and I've made two 15 to 20 minute phone calls and rebooted about 6 times because of some testing I've been doing for another thread.
Also, the Nitro does have a faster CPU that would take more power than the Nexus.
I have done all of this, in addition to in Settings/Wireless & networks there's "more..." click that and theres "Mobile networks".. and the option for "Use only 2g networks" I'm using that for only texting while at work and doing pretty decent with battery life. since 5:45 to now 10AM texting all throughout that time I'm at 85% battery.

Uhmm.. maybe its a CM9 only feature.. sorry hijacking then.
i found many of these settings are available in cm9 and after making the changes, it appears to me they work very well. thanks again eh.
UPDATE: I refrained from plugging in my phone all day yesterday and got 14 hours and 32 minutes of medium to heavy use.
Sent/Recieved 191 text messages.
Spent 2 hours and 47 minutes on the phone.
Updated 7 apps from the Play Store.
Played Dead Space for roughly 35 minutes.
Checked Facebook 3 or 4 times.
Read a news article online.
I think the battery did pretty good this time around.
Thanks for helpful tips!
The only problem I got is that the screen turned to back (with music still on) when I started NinjaJump with "Force GPU rendering'" checked.
You don't want force GPU rendering checked...

What I`ve noticed is that when I set Brightness to 100% I have 3...3,5 hours of wake working screen active time before battery exhausted. It's on ICS leak V18F. But if I set brightness to 30% or "auto" mode I got about 2....2,5max hours of screen active, it exhausts quicker
And secondly, on CM9 it helps me to check off "surface dithering" in 'performance' options. But on official ROMs we haven't this option available to tweak
I found that JuiceDefender has seriously saved me a whole lotta battery. Like seriously. I was getting 12 hours of medium to heavy usage before, and now i can hit 30 hours of medium usage. Then again, Data isn't turned on for me, I use the phone for Wifi and Calling.

JuiceDefender saved me tons of battery also. But I noticed that it was always waking my phone up for a second at random times. Have you had that issue at all?

Nope, but I don't look at my phone every waking second. Maybe it did do it. But I'm getting a serious boost in battery life so I don't really care.

For me keeping the wifi on (and thus connecting via wifi both at home and in the office) allows me to save battery..
To me it seems strange, because my old phone literally sucked battery while keeping wifi on, but on the nitro wifi consumes less than hsdpa data transfer.
I've added a link to my SetCPU Profiles file in the guide.
low antutu battery benchmark scores
Both stock and CM9 RC2 are disappointing: 250 and 328 respectively. I've applied the suggestions here and don't know if I'm doing something wrong.
I was rather happy with my phone with GB managed by Battery Defender from Infolife. I used to have 1,5 day with "Mostly Idle" usage. Now after upgrade to ICS I just got 10% down per hour on idle. So disappointed. I'll play with your settings a while. May be Battery Defender uninstall/reinstall can help too...
is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.
The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.
Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.
I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.
Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.
Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.
If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

This popped up in my head yesterday. I'm loving my M360 with it's latest update that just made the battery life insane for me. 15 to 17 hours with 60%+ Left. Woot
But Now I am wondering...
The M360 has the oldest processor smallest battery...Yet it now out preforms the G Watch and Gear live...? What? Really making the others look like a joke now.
Your thoughts?

We're just witnessing the power of software... if you have the latest processor you don't have to try that hard to get reasonable battery life.
But Motorola had bad PR from reviewers about battery life, so they were forced to optimize their code.
IMO, the fact that the life improved so much is what gets Motorola points for me. They could have made it just "good enough", but it feels like they really went all out hopefully they support this watch for a long time
Not sure where you are seeing they are being outperformed? If all things equal (both using always on set to off) G Watch battery will last much longer. The problem is that nobody compares the battery life of these devices using equal settings on both devices.
17 hours and you're at 60%?!?
I took it off at 8 am, and right now it's 3:20 pm and I am at 40%.
And I was in school the whole day so i only checked my watch for time and notifications
I have ambient off, auto brightness and lvl 1 brightness
are you using stock?
I just got this watch monday, so maybe the battery needs to set in, and I did get the latest update
My record is 50 hours with the simple watchface, ambient was off but I checked it plenty.
First day using the watch(got it yesterday). I finished school and I'm at 38% its around 5 pm and I took it off at 7:30 am. I used it a ton though, even showed off the little games to friends. Once it starts to set in, I'm sure I can get a day+ out of it.
I've gotten a good day and a half with this watch, it drains fast at first but as you use it, it will get better.

That's some amazing optimization
I haven't had time to check the various battery life threads, but has anyone (with good battery life experiences), noted whether during the majority of their
daily time with the watch - they are within connection range of their phone and indeed remain connected?
Just wondering what being out of bluetooth range/not connected does to battery life? i.e. is it similar to the situation when a phone is "polling" for
a Wifi connection or polling for a phone network connection but can't find one so the constant polling activity results in higher than average battery drain..
I personally think that the battery life discussion is one of the silliest there is. I have been always burnt by saying how great battery is somewhere. Was it Galaxy S2, HTC M7, M8 or now Sony Z3, they are never THAT good. However on Moto 360 I am really happily surprised. Even from the first day on I have never had problem with the battery. Actually I have yet to see sub 20%levels on the Moto 360. I get it off charger around 7AM and put it back 11Pm or 12AM. I usually have around 30-40% left. I use automatic brightness and ambient off. I do get a lot of notifications.
But the much praised Z3 goes to charger much sooner than this watch. Sure, I couldn't go on for the next day but it doesn't matter if I can make 20 hours easily since I never sleep with my watch on the wrist.
So, you are saying you get 5hrs of battery life and that's great?
7AM - 12PM. That's only 5hrs. Lol

Uninstalling helps battery? I might try that today for shiggles.

I've had the G Watch since it came out, and the 360 for a few weeks now. All things being equal, the G Watch goes an extra 12 hours easy, but it sure isn't as good looking as the 360, so it had been relegated to just morning gym sessions now.

My thoughts are that many of us get nowhere near those numbers, and you must be barely using your watch with almost everything disabled to get 2.35% per hour power consumption.
On my watch with latest firmware, reset after the firmware was installed, no apps at all, ambient mode off, step counter on, and default brightness, I cannot get below 3% per hour with almost zero usage, and hover nearer to 4% per hour with real-world (light to moderate) usage. At 17 hours, I would have at best 49% remaining, and more likely 32% remaining.
And that's with ambient mode off. Enable ambient mode and even with light usage and no apps at all, my watch will regularly fail to make it through a single regular, 16-hour day (that's the time between waking and sleeping with an eight-hour sleep cycle, which is the most a typical adult gets).
Also, what review have you seen with the G Watch or Gear Live using their latest-available firmware, so you can make a valid comparison? Because comparing the Moto 360 on its latest firmware against those devices on early firmware is utterly unfair and meaningless.
The Gear Live massively outperforms the 360 in regards to battery stamina. I don't understand how you guys are getting 50 hrs on a charge. I do like ambient mode, but I can still kill a battery in 12 hrs easily.
I had excellent battery life before the Sept & Oct updates, now the battery life is terrible. Used to have an overnight sleep rate of about 0.5-0.7% /hr, now it's around 1.5%/hr.
Also, AccuBattery consistently estimated my battery capacity at around 3850-ish (I charge to 78% and pull the plug) but now it's lucky to get to 3650.
I've been through a ton of settings, disabled Background on plenty of apps, set up as many as possible in Sleep & Deep sleep.
Did Samsung screw up these updates up for anyone else?
I think I've worked it out - I don't let Google Play auto-update apps (too many times new versions are total ****e) and there were about 48 apps waiting to be updated. There were a bunch of other Samsung and Google apps that were updated without my intervention before this.
After hitting Update all and cancelling the two I don't want updated then a reboot, the standby consumption calmed down a lot. Was it the Google Play queue or maybe the other apps needing the reboot? Dunno, but I'm glad the sleep battery drain is almost back to where it was.

At the very least update one apk at a time and never do a firmware update until it's been proven especially if you have a fast, stable platform...

Medium Power Saving,I use it while I don't play games (rarely).
Story continues ... battery drain was getting quite high on standby, despite me barely using the phone and mucking around with Medium Power Saving, Adaptive Power, etc. Got quite low the other night (20%) so I put it on Supercharge and decided to turn it off while charging to 100%.
I know, I usually avoid charging past 80% but I've only done 3-4 full charges since getting the phone in April.
As soon as it hit 100% I unplugged, power up, did all the usual unlocking, checked the battery was on Optimised and Adaptive Power Saving was On, then closed the cover for the night.
Next morning I was really shocked to see it had only dropped about 5%. The phone has been running nearly 46hrs and the battery level is at 50% ... nice.
Accubattery stats
21% screen on 40m
29% screen off 45h5
Deep sleep 41h39m
So maybe the battery needs a bit of exercise every now and then ... ?
It's been a few weeks but I finally tracked this down to the recent A10 updates screwing up 5GHz Wi-Fi somehow.
I saw a clever suggestion about putting the phone into Airplane mode, so I tried that with the battery charged to 100% and in the morning after about 10hrs the battery had only dropped 2-3%, which was amazing (to me).
So over the following weeks i alternated between airplane on/off and 2.4GHz vs 5Ghz Wi-Fi, to confirm what I was seeing, finally abandoned the 5GHz connection and the standby battery drain has been much more to my liking.
One of the tests involved leaving the phone on 5GHz with it sitting on the desk beneath the Ruckus WAP all day and the battery drain was again quite high despite having a super strong signal, so it's not a signal strength issue.
I can't imagine what Samsung have done to screw up the 5GHz channels but I'm staying away from updating to A11 for at least 6mths, maybe never.
OneUI 3 and A11 seem to have introduced a load of other problems which I'm sure will settle down in time, but I don't need to be one of their guinea pigs.
Tks to all that participated here, suggestions were definitely helpful.
I've got myself a new P6P and basically since day one, every night or every other night it would lose something like 15 to 25%. This is over roughly an 8hours sleep.
Device is connected to WiFi and always on display is disabled.
Gram battery graphs look scary, like Oreo times scary.
Is anyone else experiencing anything similar, or is it just me?
Hibernation while screen off seems totally off at 27% of the time (should usually sit around 90% unless for example streaming or downloading stuff with screen off).
My previous P5 would do considerably better, with an almost flat graph in the same test conditions.
Thanks!
And the most frustrating about all this, is that in 2021 Google still can't provide us an easy way to figure out what's wrong.
Over several iterations they've promised we wouldn't have to deal with crap like this ever again (Doze, Doze on the go), but ultimately when it happens, users have no clue.
I'll have to install battery historian once more. I thought I was done with this crap.
P.s. I'm of course very interested to know what YOUR numbers look like in similar conditions. Thanks!
Hey,
I was having a similar issue on my P6Pro with high idle drain (about 1.8% to 2% per hour) using AccuBattery Pro to measure over the last week (got my device last Tuesday).
I just rooted last night so effectively did a fresh install on the November firmware. I turned off AOD, Digital Wellbeing and Lift to Wake as part of this.
I haven't really used root to prohibit anything I couldn't have done without root (yet) and last night used EXKM to track stats.
Over 7 hours I only lost 2% battery and had idle drain of 0.28% per hour which is much much better.
You've already said AOD is off but not sure about Digital Wellbeing. I'm not sure if the factory reset and setting up straight on November firmware helped the situation but might be worth a go?
I quite agree. Everytime I get a new device (have usually been from Google), I have to start off troubleshooting battery drain and installing other apps to do it.
Android 12 has light doze now, so after just a few minutes it will stop apps accessing the network, and force apps that need to get some data every few minutes or so, to all queue their requests for the next maintenance window, so this should very quickly after the screen is off, allow the phone CPU to enter deep sleep for most of the time, i.e. nothing is running in Android until the next maintanence slot.
What is likely happening is there is a wakelock stopping the deep sleep from happening, and Andriod remains running doing very little, keeping the CPU awake ticking over at 300MHz.
To test this theory install CPU Spy https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en_GB&gl=US Have a look at the stats, has the phone entered deepsleep and what is the percentage of deep sleep? Overnight the phone really should be able to get at least 80% deep sleep as no one is using it (I've seen 95% on tablets and my Pixel 2 XL overnight).
To run a quick test, reset the stats, and let the phone sit for 30 minutes or so without being used, then go back to app (will need to use Refresh to get the latest totals) and see what percentage you get of deep sleep.
If you find the phone is going into deep sleep okay and overnight is 80% or more of deep sleep, then that isn't the cause of your battery drain, and it is likely caused by either the modem flapping or constantly trying to register with a cell tower, or perhaps Wi-Fi. So your next test is airplane mode overnight.
My overnight losses are around 5% at the moment, I'm only on Wi-Fi overnight, the mobile network is off as I get next to no signal.
Mine dropped 20% in 8hrs over night, seems a bit excessive.

Hey,
I was having a similar issue on my P6Pro with high idle drain (about 1.8% to 2% per hour) using AccuBattery Pro to measure over the last week (got my device last Tuesday).
I just rooted last night so effectively did a fresh install on the November firmware. I turned off AOD, Digital Wellbeing and Lift to Wake as part of this.
I haven't really used root to prohibit anything I couldn't have done without root (yet) and last night used EXKM to track stats.
Over 7 hours I only lost 2% battery and had idle drain of 0.28% per hour which is much much better.
You've already said AOD is off but not sure about Digital Wellbeing. I'm not sure if the factory reset and setting up straight on November firmware helped the situation but might be worth a go?

I'm super paranoid about this stuff, and so since I knew that an OTA was in the pipe when I received it, I just skipped the first time setup to go straight to System Update and install the OTA
Then I factory reset, and only THEN I set it up properly with my Google account etc.
So I guess this answers your question
Digital Wellbeing is on for me tho (lift to wake is also off, as it tap to wake - although there's the bug, I think, which would still enable the screen in B/W mode when phone is lifted).
2% in 7 hours is awesome, that's what I'm aiming for, but I'm really not willing to root
I guess I will re-factory reset and maybe installing apps in batches, instead of all in one go...
EDIT: just re-read your post and you said you haven't made any of the root-enabled modifications yet, so even more call me amazed. I guess I'll also try disabling Wellbeing at this point...

It is, especially if you consider that it's 1000mAh.
A Pixel 2 XL dropping by, say, 10% (which is still much higher than what I used to get), means a consumption of 352mAh.
In terms of efficiency, a crappy P2XL performace is still thrice as efficient as what we're seeing here on the P6Pro (and ideally tech should move forward and become MORE, not less, efficient...)

Yeah,
In terms of root, I hadn't done anything with root until this morning really so there shouldn't be anything affecting my idle drain figures that you wouldn't be able to do without root.
Otherwise, try turning off all digital wellbeing features (bedtime mode, timers and focus mode) and remove permissions to digital wellbeing and then clear data. Try that for a few days and see how that has an impact.
I've noticed the same issues, I would normally have my phone switch off over and and switch on but this doesn't seem to have that option

Quite agree with you there, my Pixel 2 XL often goes 5 or 6 days without needing to be charged, although to be fair I'm working from home and it gets little use during those days and only on Wi-Fi for most of it. so not typical usage. I don't think the Pixel 6 Pro will go as long, in theory with exactly the same usage it should go for longer as larger battery and newer chips sipping less power, certainly when doing little in standby.
Too early to tell if the Pixel 6 Pro can better 5 or 6 days as I've been playing with it a lot more, but in theory it should without question, so something is seriously wrong it it can't.
As for the Pixel 2 XL, I dip into it now and again, and the one thing I'm missing on the Android 12 is not getting true black, why have they made black dark grey on all the setting pages etc? Why reduce contrast? I'd love to be in those design meetings just to see what rubbish they come up with to justify some of these changes.

IIRC full black will cause smearing while scrolling. And the display of the P2XL was, let's say it, crap.
The Pixel 2 XL display looks absolutely fine to me, and I have never seen any smearing when scrolling. When we had LCD everyone was raving about OLED having true blacks, and everyone wanting a dark mode, now in many places in the UI it looks worse then most LCD panels for contrast. So its now fashionable to have artificially lowered contrast.
Android 12 DP2: Dark theme on Pixel gets even lighter
Android 12 has tweaked dark mode again in its second developer preview to make it even lighter than the previous release.

Google, give us the option to change it back, it is suppose to be Material You so we can go back to customising again (like we once had), but it seems the only options now are washed out pastels.

Can you monitor with BetterBatteryStats or similar now you have root to see if there's anything in particular using the phone during idle?
How do I turn off Digital Wellbeing?

I can but from what I heard in one of the TG groups today, BBS isn't working properly due to changes in Android 12.

Go to settings, Digital Wellbeing and turn off all the options if you turned any of them on. Go to Settings, Apps and then find digital wellbeing and remove all permissions, then within that section also wipe data for Digital Wellbeing. That pretty much resets it back to stock. Without root, you can't freeze the app or remove it but this should be good enough.

Ah, damn.
Guess it'll be 'top' or 'htop' in terminal then for now.
Mine lost about 7% overnight last night. I've read on this forum that they aren't sleeping well. With two adb commands I installed Nap Time by Francisco Franco and it seem to be going into a deep sleep when not being used now.

I've got NapTime as well. The trouble is light and deep doze is just the Android OS restricting what apps do and forcing them into maintenance schedules so things are done in batches. So its an app thing rather than a low level forcing of the phones CPU to sleep, so even in light or deep doze it doesn't guarantee that Android has been halted and the CPU is in sleep, that is another thing step. It should make Android more likely to suspend and the CPU to go to sleep if Apps aren't allowed to chatter over the network, but deep doze doesn't guarantee the phone has gone into standby.
Other things can prevent the device from truly suspending and putting the CPU into sleep mode, so other things may be happening, it might not be an app issue.
To check how long the CPU is in deep sleep (essentially the phone is off and Android is suspended and is what we need to see so top battery drain overnight) CPU Spy can show you that, currently mine is showing 82% deep sleep overall. When you see a low percentage of deep sleep and high percentage at 300Mhz, then something is stopping the phone for sleeping, so it is kept awake doing little so idles constantly at the lowest CPU clock speed, but this still uses quite a bit of power compared to deep sleep.
The age old question for those of you having battery drains, Did you turn off wifi scanning?
