How long your phone keep on without charging? (the USB connections IS charging you know ) (please write the common usage (Wi-Fi, BlueTooth, call time, etc.))
Is there any difference between PC charging and charger charging? (speed, quality etc.)
Yesterday I have FULL PC charge and after 12 Hours of active usage (20-30 min Wi-Fi, 20-30 min. talking, 10 min GPRS, 20 min other staff like gaming) the phone turn off.
12 Hours are not much .
If I charging with charger I will have better time?
10x
i think that when you switch off the phone when you want to charge, the battery take too long. sorry for my bad english
I understand you. Maybe you are right. How long can you use your phone without charging?
Around 3-4 days if I try.

In this 3-4 days how ofen you talk to phone and use Wi-Fi?
Phone conv are not draining battery a lot
Same for bluetooth
WiFi more
Backlight, gaming and GPS prog a lot
So first, reduce backlight and screen timeout to minimum
Then find a prog to kill unneeded running applications
With 1H phone conv/day -> 3 days
+ BT 2,5
+ Wifi and/or gaming -> 12H
Less for phone+BT+GPS
The 620's best friend is a mobile loader
I see.
10x for the info.
What it mobile loader?
Do you use USB charging or charger?
Is there any direrence?

Hi,
I use mine all day with wi-fi and a few hours with BT on, so I bought this charger kit and I'm not worried anymore for the battery life...
i usually use usb charging when i insall program and i dont know exactly how long i use it. but when i used wi fi the battery dont survive more... i dont know. maybe you have installed software that consume your battery.... for example photo contact...
I have optimized the system, and don't use the Photo editor or other heavy programs. My girlfriend plays on bubble breaker for 30minutes per day .
Maybe Wi-Fi uses more power than I think.
Empel1960 I am poor Bulgarian man - 30 bucks is much for me . I bought this phone for about $250 and I am out of money .
I have simple USB wall charger and I use it because my original charger is on US standart, and all bulgarian power slots are on Japanise standart. I think that maybe if I found an convertor for US to Japanese standart and use original charger maybe the speed of charging will be more.
what software do you use to optimize your system?
I just keep clean startup directory (there is one icon for WiFi), don't use software who need to be ON all time (plugins, trackers, reminders, etc) and every time when I end some activity on phone, like gaming, browsing, using camera end so on I use Celetask to shutdown all programs and optimize the RAM. I believe this reduce the power needs of the phone.
For celetask see this:http://forum.xda-developers.com/showthread.php?t=375451
i can find it too in wm 6.1 or not?
I got my Dash about 8 or 9 months ago and it started with WM5. I then upgraded to WM6, and now to 6.1. Over the course of the 8 or 9 months I have slowly noticed my battery go to $h*t. I stopped using my WiFi because of how much battery it would suck up. Now I text a lot and my battery won't even last me a full day. I have to charge it while I'm at work and most likely charge it when I get home. Time for a new battery I'm thinkin.
FYI,
A lot of things determine battery drain. Wifi, Bluetooth and WMP are always hungry and consume battery a lot. Than Radio (some radios require more "juice" according to the hermes, also some radios that work in Europe don't work well in the states or "down under"). Another thing that I noticed, WM6.1 needs more power.
In the end, most important thing is how you charge your battery from the begining. Never let your battery to go below 40%, It is better to do several charges than a full recharge.
Cheers
I have the Dash and I had my battery for about 7-8 months before it wouldn't keep a charge for an hour. When I called T-Mobile they said that was pretty much normal. The upside was I bought a desktop stand with a new battery on ebay for about $17 USD shipped. The battery is working extremely well. I figure by the next time the battery goes out it will be my excuse to get the Sony Xperia X1.

I don't know how money I will give for shipping battery to Bulgaria... It is not normal for me to change the li-on battery in 7-8 months...

Honestly it's not normal for me either. I haven't had a battery go south like this before. Usually what happens is I end up getting a new device between 1 and 2 years.
I charge it all night using the home charger. Then when I get to work i play music through bluetooth and only lasts for about 3 hours before i put it back on the charger at work. Suckss
This is the price of thin design .
I will be happy to use it for more than 24 hours without charging....
Today was my first day at work since i got my Desire on Sat. So it was the day without regular charging.
Firstly, reception was poor as compared to what i was getting with Touch Pro 2. Same network (Orange), same place, less signal bars and less 3G coverage.
Secondly, unplugged phone 7 o'clock this morning, 100% charged. All day only had time for couple of calls (10-15mins). Used internet (3G when available) for max 20-30mins. Tried couple of games for 15-20 mins and at 7 o'clock at night, the battery was 15%. This is not a heavy use by my standards. Used to do a lot more on Touch Pro2 and battery used to last 2-3days. (I know the capaciy difference btw Desire and TP2 battery but still, Desire should last atleat > 24hours)
Not sure if all these issues are related to Orange ROM/Radio. Will we (on Orange) get OTA firmware update like T-mobile, which has apparently improved their battery life? If not then ...... :-(. Not satisfied with the battery life. Shame it is such a good phone but battery life and signal strength is putting me off.
Whats the fun if you have a "superphone" in your pocket but cannot use it to its full potential due to these two isuues.
Mine was the same,
But after a weeks worth of usage, its now reasonable, IE 18 hours between charges,
Fon22
I totally agree, there are other posts telling us to turn off or reduce all sorts of settings, its ridiculous that you would have to run any phone at less than its full potential just to compensate for a poor battery.
Sure you could buy a second battery but if that was necessary then they should put two in the box
If you leave gps on then you are asking for trouble, a lesser extent wifi. Having a toggle on off isn't such a hardship though. Poor signal hammers the battery too.
I easily last the working day (7-7) with an hour of music and 2 hours surfing and a smattering of calls and texts.

Come on guys, if you have a laptop, and you turn on bluetooth, wi-fi, play some games etc, it WILL run the battery down faster. It's just common sense. Just because this phone does heaps of things, dosn't mean it will last forever. As phones get more features, they are getting worse battery life - in general. And android is a data centric device, I would get used to it, or simply turn off some synching features if you need to get through more than half a day. Or perhaps get a spare battery etc.
Just out of curiosity did you have your previous phone to constantly sync throughout the day for time, email, google account, marketplace updates, location, weather using gps, 3g, hsdpa, accelerometer etc? Remember some of these connect are activated every 5 mins or so. Will make it worse if you have poor reception. COMMON SENSE PPL!
My issue is that even after the T-Mobile update, last night I charged phone on this time and it would only get to 98% again. Then drop down quickly.
If I charge it off, It seems to be ok (although I will test this again.)
Frustrating.
My battery life is woeful (TMo uk, updated firmware). I've been trying to figure it out using Juice Plotter to record power usage. Basically, whatever I'm doing, if it's on the battery falls off a cliff - I'd say 10% per 30m and my first impression is that it makes little difference whether networking is enabled or not. This makes little sense to me, I've always found in the past that 3G is just about the most power intensive activity on the smartphone, but it's consistent with some experiences I had flashing roms on my Blackstone - some of them would just run the battery down, others would go for ages. One hypothesis is that when a phone is in that kind of "sick" power state, the drain is not really related to which facilities you're using, but something deeper - perhaps the CPU is running full throttle all the time, or something else. I have no idea what's going on right now but I know I have an unusable phone which lasts half the time my Blackstone did with heavier use. I think many others have the same problem and I wonder if there's a bad batch. Bad news if so as we'd have trouble proving it and getting exchanges.
My next step I think will be to hard reset and run it in a very basic mode for a while, maybe some of the apps are causing it.
I'm also finding out that battery life improves dramatically after the 5th 6th charge. When I first got my Desire I could barely make it through the day, after properly charging and letting it discharge all the way to 10-15% now I get 18-20h of battery life with wi-fi on non stop (but with the setting to to turn itself off after 15mins of inactivity).
I was very worried about this when I first got the phone, but now it's starting to be better and better at battery life. I know my demands from a smartphone when I buy it and if a phone get's me through the day I'm OK with that, plus I have chargers at home, in my car, at work, so it's not a problem
I've got one of the very first batch of T-mobile Desires that were shipped on 26th March. It has been updated with the T-mobile 1.15.110.11 patch.
I last charged it on Saturday afternoon. I've only had to start charging it again this morning Tuesday. I've been making a few calls, probably 10-15 minutes total. A few texts. Browsing with G and 3G, maybe a few of hours worth in total. Little bit of Bluetoothing, though that's only a couple of minutes worth. I've had it down the pub a few hours where the T-mobile signal isn't brilliant, so it will have been doing a little "shouting" to find and communicate with the nearest T-mobile mast.
But that means it's lasted a good 66 hours admittedly with fairly moderate use. GPS, Wifi and Bluetooth are turned off unless needed. And it's not regularly Syncing with Facebook, Twitter and all that stuff. The only regular syncing is the weather.
Not sure if these are bugs with some hardware/software or standard functionality with your usages. I'm getting excellent battery life with my usage patterns/settings and far happier with this than with any of my previous devices, since this adds an exorbitant amount of power-draining functionality and flexibility over them too.
- Heaviest use is netting 28-33 hours.
- Typical use is getting minimum 3-3.5 days.
- Light use (also the norm for me me) lasted 5.5-6 days.
- Basic inconsistent call/message/email/net/stocks/news/stop watch/GPS/ compass/notepad/office/weather/ vid/pic/audio throughout the day kept the battery at 84% after 24 hours. 3G off, using WiFi. I don't keep any but the needy apps/settings running BTW.
- Charges to 100% always and stays up there consistently as expected.
However there is a pertinent aspect yet unmentioned;
Biggest difference between my usage and the typical internet crowd is that I don't use or bother with "social networking" (Facebook, MySpace, Twitter, etc) or its likes nor do I play any games on this (hence sync with such apps is off and any updates are set to manual). However rss feeds, e-mail and IMs with close ones I do use during the day when I have spare minutes.

Same situation as mine there.

I'm deffo leaning now that there are faulty batteries out there causing the problem. I can get good life if I can get the battery to charge properly. but when it doesn't battery lasts hardly half a day. I don't use any apps that require automatic updates (all manual or off). But net on drains it very quickly (if I leave data on). Faulty Batteries I feel.
My Desire has a better ability to hang on to a weak signal than my other phones. I am on T-mobile. Battery life is adeqaute, in that, I can get through a day of use before a charge is needed. Will switch-off GPS and see what happens -I never had GPS on all the time on my other Smartphones.
Coming from a G1 that could barely make it through the day on standby this phone seems pretty good.
I got mine last friday it has just come off of it's third charge. I charged it for 3 hours when I got it, ran it right down >10% then left to charge up fully again.
I installed JuiceDefender and bought the UltimateJuice upgrade as soon as I got the phone.
Day 2 (with JuiceDefender) - battery lasted 13h27m, thats with WiFi, phone calls, MMS, 3g, internet browsing/showing it off to mates in the pub and then listening to an album on spotify in the car.
Considering this is a new battery and it still needs several charges before it is working at full capacity, I think that is pretty good for a smart phone! It can only get better, right?
JuiceDefender - I can't recommend this app enough, I don't want to mess about with Task Killers (that don't really save battery), I don't want to stop stuff syncing (because thats the whole point of this phone) but I want to optimize my battery life to get me through the day and this app does it so well!
I've currently got it setup to turn 2g/3g off when in standby but set to turn data back on every 5mins for 30s to allow apps to sync. You can specify a longer interval which will obviously save more battery over the course of a day. The phone connects back to a 2/3g connection so quick when you bring it out of standby so your not waiting around to get back online.
Switch on WiFi at known locations - I have this setup because at home, 3g signal is a bit patchy and it probably uses more battery constantly trying to get a 3g signal all the time, than it does if it is just connected to WiFi.
Turn data off between 2am-8am while I am sleeping.
Turn data off when battery is below 15% - with my G1 it would hit 15% just as I'd be heading home on the train in the evening, so I'd turn data off just so I could send a few texts or so I had just enough battery to make a call. So I figured I might as well use that last 15% battery for basic phone operation and give me enough battery to get home! I probably don't need this with the Desire though.
Any one else using JuiceDefender?

WOW, can I have your battery please ...
What did u do to get this powerhouse. Was it weaker in the begining and got better with charges or was it like this from the begining?
I dont use GPS at all. Only for navigation, when in car and then it is on charge. Normal day.. no gps, no auto data connection - do it manually when internet connecttion is neede. But battery doesn't last a day, merely 12-14 hours. Charged 3 times yet, only 3 days old Desire.
I cant find juice defender in the market?
When I first got my Hero I remember my battery life being terrible, most of it was down to fiddling all the time, however over time my usage changed and the battery had been charged a lot the life was a lot better. Also there were a number of radio upgrades installed, which probably helped.
Since I've got my Desire, the "desire" to fiddle hasn't stopped and I feel as if I'm in the same situation as I was with the Hero.
My opinion is that over time the battery life will be better, as with the Hero.

Yes both Ultimate Juice and Juice Defender are in the Market.
Juice defender was missing for me a couple of hours ago. But actually, when I installed it thinkgs started to go wrong for me. May be a coincidence, or may be a conflict with some other sw.
Following shocking power drain, I have hard reset, and left it with nothing syncing and all networking disabled. As you'd expect, battery level is barely falling in standby. Now to start adding things back in and see what efects it has. First step is to spend 30 mins browsing over 3g, previously this would take out 10% of my battery.

I've always been impressed by the battery life on Defy ever since I owned it. I haven't owned other smartphones before to be able to make a true comparison but using electronic devices for a long time I can tell the battery usage on Defy can be impressive. However, there were times I noticed the battery was drained so quickly.
In my latest watchful examination of battery usage I have achived to use only 30% of the battery for more than two days. Here is a summary of my usage in the past two days;
4 Hours Music Playback (PowerAmp)
30 Mins wireless
About 16 hours airplane mode
No phone calls on my mobile but I did dial a number several times
I have fully charged the mobile on Friday morning and on Sunday morning the battery has 70% charge.
Hint:
As it was stated in user manual it is recommended to charge the phone from mains socket whenever is possible. I can confirm that I've seen battery improvement after recharging the battery by mains socket after several times.
Since I don't have a use for MMS I have renamed the APN server. The same trick can be used to disable data and that saves battery life too if you don't use your phone to push/pull data.
In the past 2 days my network type has been set to 2G only. The automatic setting certainly have dramatic affects on battery.
Before going to bed I put the phone to airplane mode since the reception in my bedroom is very weak and this increases the battery usage.
With simple measures the battery life can be extended (noticeable) more than what you'd expect.
I'm very pleased with the battery usage so far. Nonetheless, I will buy a spare battery as soon as it is available in the UK.
Happy New Year XDA
Yours are the most impressive stats for the battery use. I've set my Defy into saver mode, and the network data to 2G as well (I only use it to sync up with Gmail (plus Calendar and Tasks) and my employer's Exchange email) and get down to 50% after two days of moderate use, which is enough for me not to worry about running out of juice if I'm away from home for a few days. Yes, the Defy can be pretty frugal with battery use.
I ended up having my original Defy swapped because of concerns that the battery wasn't up to scratch and the new one's been brilliant.
I'm in 3G all the time, never put it in airplane mode, and after 62 hours I still have 20% left - that's with me having used it for some calls, texts, web browsing, facebook and a good couple of hours of Angry Birds as well.
Definitely the best smartphone around for battery life IMO.

What does mains socket mean? The wall outlet (I am in the US).
If so, how else would you charge? Computer USB?
If its the bit in the wall that the electricity comes from then its the same thing :L and yeah you can charge it from a computer USB but it takes a little bit longer

If Motorola Defy's screen size was 4" and it had Froyo ROM already I would have bought two of them just out of excitement.

Yeah, seriously.
I'm not talking about hours of calls, more like 15 minutes or so. Maybe an hour or two total web browsing and facebook and perhaps an hour on Angry Birds.
Part of the reason it lasted so long was that I just didn't touch the phone on Christmas day at all, so that was 24 hours with basically zero use, which is unusual.
The next charge last more like 2 days, which I think is closer to how I'll be using it normally.
if you put it in air plane mode, and a couple hours later u turn air plane mode off. will u get all of your notifications? like calls,texts and stuff that people sent to u while the phone was in airplane mode
There is true gem on the Market named JuiceDeffender Beta - I used it since my Milestone and it really does what it says it does. All the hints you mentioned already included in the program and are being controlled by it. For example, as soon as you display turns off your network automatically switches to 2G. In paid version you can even adjust processor's speed when needed (underlocking of course, in terms of battery saving) However i am currently on free version and it's enough to make the battery last almost twice as longer.
I had some problems installing it on Defy, but they were all gone as soon as I rooted the phone.

How did you get the 3G -> 2G to work? I can not enable that feature, as I am not using a CyanogenMod rom and I can not download/install AOSP helper as it suggests. I am using the beta and UltimateJuice, which I purchased after seeing what features it provided. I'm using the CPU features to do what SetCPU did for me - no need to have two packages with overlapping features installed.
*update*
From the author of JuiceDefender:
In practice the only ROMs known to work are CyanogenMod (any version) and the Nexus One stock ROM..

Hey XDA
I'm having absolutely HORRIBLE battery life with my GIO. I've gone through extensive testing to find the root of the problem but nothing seems to be the cause. So far i've had to charge twice, maybe three times a day.
So here's the story. A couple of months ago I noticed my Gio's battery was dying quicker so I flashed another rom [Particle Mod] over it. I was happy, until I found out the problem persisted. Then I flashed a 2.3.7 Cyanogen mod, the battery still wasn't lasting and the battery life was only slightly worse owing to CYMOD.
I then flashed the GALAXYICS beta, and it's getting even worse. I've even bought new 1600mAh batteries to see if it was the battery's fault. Apparently not, so I went back to stock for a day or too to see what it was like, and I was still lucky to get 12hrs out of it with featherweight usage.
I simply do not know what to do, I've tried numerous battery mods [flashable zips etc] and they've only done a tiny bit. Lately I've been playing with clockspeeds but it seems to only make a difference if I raise the minimum speed, the extra top end performance is nice though.
So, what I'm saying is this normal for a Gio? Is it a hardware fault? software? 4th dimensional? I'm at a loss, and I think the infamous Samsung cell standby drain is to blame.
Attached is screenshots of general battery screen, Cell standby and the Graph. I've been switching between 2G and 3G, Airplane mode on and off, and listening to music for an hour or so and It seems to have utterly crippled the device doing simple tasks, and I've done EVERYTHING to minimize the drain by lowering screen brightness to %0, turning off vibration, animations, wifi, GPS, BT, radio, everything except google contacts sync and a couple of root things in between like deleting the batt stats.
The new batteries help somewhat, but I still can't last long enough for a single school day... FFUUUUU!
I really don't want to have to buy a new phone, I'm only 14 so I can't work to get one, and I can't just ask my parents because then I'm just being a spoilt brat. I want to make this phone last as long as possible [Until I can work for a Google Nexus or something] and the battery isn't helping.
Thanks for reading.
Yeah you're a spoiled brat. This is not great but not extraordinarily bad. My epic 4g touch spends the day on the charger.

Well, it seems to be all right with your battery. And your '1600 mAh' battery was just a fake. A lot of people get scores like this
What I am worried about is not so much the capacity, it's the RATE at which it drains. I see a lot of "stair steps" on my graphs so I'm not so sure, especially when checking the other phones in the house "a Galaxy Ace and 2 HTC Incredible S's] they seem to have a more consistent curve, I notice my batteries will drain by as much as %5 in half a minute, which is either a reporting bug or inconsistent strain.
Have you tried to do a wipe and test it with no installed apps?
Do not trust the "stairs", it is just bad reporting (as you said).
In my case when I switch on 3G or WiFi, it happens that the battery drops by 10% instantly.
The only value that is relevant is the total duration between a full charge (100% charge + several hours still plugged) and the "low battery" indicator.
According to my own experience, the things that drains the most are :
- 3G network : this is the main factor, by far.
If you can, try to stay in 2G mode most of the time, switch to 3G when needed, and as soon as not needed anymore go back to 2G.
- WiFi / BT
If you switch On/Off very often, or is always On and you moves very often (changing hotspot), then WiFi / BT will be a very important battery drain factor.
- Multimedia
Videos / MP3 drains battery a lot.
If you can, switch to "airplane mode" or switch off the phone during night.
Finally, with 3G / WiFi / Multimedia usage mix, a "One Day" autonomy is good.
I'm sorry but you will not find any smartphone that can pass "One Day" with that usage type.
With my own usage (very few calls, sms, wifi) and with above tricks, my Gio lasts 4-5 days.
PS : As you mentioned, available ROMs are very unequal as far as battery drain is concerned.
Stock ROMs (and moded ones like Adrenaline) are the champions of battery life, while ICS ROMs are the worst.
CM7.2 ROMs are in between.
I agree with Vilo76. When you don`t have wireless or 3g, or play any music/games, you can actually get a few days of life from your phone, but if you do some of the stuff i just said, the battery life is going down like crazy...
The only think you can do to get some bit of juice out of your phone is if you format your battery, but actually that is just for a better battery reading, not actually extending your battery life...
By the way, I can't figure out why phone manufacturers don't use more long lasting batteries ...
There are many many examples of batteries that are about the same size as a phone one, but deliver way more mAh.
Among others :
- House wireless alarms keypad batteries are the same size but can be as much as 3000mAh ...
- Classic cylindrical AA or AAA accu can be as much as 4000mAh ...
While a typical phone battery hardly ever exceed 1500mAh.
Okay, I'm back and I have some results for today
3G Is DEFINITELY using more in Australia on idle, while 2G is a bit less brutal
There is something cause my phone to wake intermittently, I've turned sync and location services, and killed any apps that may be checking the net etc, but it's still waking up with screen off.
---------------------------
Today I decided to do something bit extreme, I ran the phone an airplane mode all day with the original "dead" battery, I only lost %20 all day with 1hr or so music usage, phone standby is up but Cell standby isn't there at all [Obviously].
Something's telling me that's it the cell radio and whatever is waking my phone up is causing the suck. I'm upgrading to GalaxyICS CM9 beta10 today with a full dalvik, battery and cache wipe, so we'll see how that goes

Good news this time! I've installed a Cyanogen Mod 7.2 on their [The one that's updates through Goomanager] and the battery is holding steady at 100 idling for 1hr on 2G.... Not sure if I have to calibrate but I think I've fixed it, it's working better than stock!
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Google Pixel's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
First night dropped 12% in 6 hours. Not impressed. But I gotta break in that battery.

I've been losing around 3 % to standby drain over my typical heavy 9 hour sleep (Rx induced)!
I've had mine since last Tuesday.
5" Pixel version.
Battery doesn't seem to go down unless I really get on device for a couple minutes.
Wheee!

Last night my pixel went down 2% over about 7.5 hrs so the standby time is pretty good.
My Pixel actually dozed for it's first night. We'll have to see if it keeps going. My N5x gave up dozing a long time ago.
The doze mode has been great for me so far. Standby time is better than any other android phone I've used.
From my other reply:
Battery has been pretty good for me so far. Seems to be settling in with optimization after a few days. Dropped 0% overnight last night which is awesome.
GSAM Monitor is saying my average is 19 hrs on, 4.5 hours of screen on time usage, 1-2 hours of screen off usage like phone calls, music.
EDIT: I also have pretty crappy signal at work.
Stand by time hasn't been a real problem for awhile. My Nexus 5 on KitKat and Lollipop(both before Doze) and only a 2,300mAh would only drop 2-3% over 8 hours. It's usage time that really matters.
Mine dropped about 10% the first night (Mon 24th), but I do live in an area that has poor reception. Have to place phone next to window just to get text and calls. If I go outside I may get LTE at 1 or 2 bars. Overall though battery hasn't been an issue and I love the rapid charging.
Am I the only person that turns their phone off at night?!

Good lord man!
My phone is my alarm clock, so I couldn't do that if I wanted to.

I'm "blessed" with an extremely good body clock, which means I wake up at 6.30 every day without any alarm... Even at the weekends

Yes ! Now a days u are lmao
doesn't the alarm still go off when it's turned off? my galaxy note 4 does that
Probably.
Using Accubattery to measure screen off battery drain I am typically between 75-85ma. Has anyone else measured their standby power consumption, curious what other values are as this seems high to me.
Edit: more info
Tested it overnight with and without bluetooth on, got it down to 40ma without bluetooth, averaged 70ma with bluetooth on overnight. Also got to test a Note 4 under the same conditions though without a SIM card. The Note 4 was using 11ma without bluetooth and 18ma with bluetooth on. Both phones connected to the same WIFI the whole time. May have to do a full reset on the Pixel as the standby power consumption is definitely out of hand.
Standby
My Google Pixel currently drains an excessive amount of battery even on standby, however thanks to quick charging its up and ready in 15 minutes. OS seems to be heavy usage of battery at the moment.

While I still think the Samsung will have slightly better standby drain, this isn't a good test. You cannot compare a phone with a cell signal to one without. The biggest battery drain on a phone is typically cell signal.
If you pulled the sim card out of the pixel and let the phones sit side by side overnight, that would be something.

I agree, this test is not a great comparison. The Note 4 did still have cell signal as they do connect to service without a sim card, but likely it is not the same as having proper service (LTE). I was trying to get the lowest draw possible on the Pixel and managed to average 29ma in airplane mode. This is the lowest I have got yet with the device which although is decently low draw is still abysmal considering that it had no apps running and no radios active. What is even more interesting to me is that google claims that the phone has 456 hours of standby time which suggests radios active (at least cell), unless my math is wrong this works out to a standby drain of 6ma which at least on my phone seems to be completely unattainable even with radios off.
I have looked around the forums but haven't seen anyone else posting power consumption information with the regular or XL pixel so I have no idea if this is unique to my phone or just standard with the Pixel. I haven't yet factory reset the phone but that would have been next, except that I am exchanging the device due to an unrelated issue. I guess I will see how the next one stacks up in this regard.
Thought I would post an update on my findings. After getting a new device and still having issues I have an answer and partial solution to my terrible standby drain. The culprit in my case is LTE. I am on FIDO in Canada which does use Band 4 though I am not certain if that is being used in my area. Anyways if I set my preferred network type to 3g my standby drain improves dramatically as the device idles around 10-15ma in my pocket and overnight is more like 6ma which is phenomenal. As soon as I set my network back to LTE my standby drain is 70-90ma and at best 40ma overnight if I'm lucky. My cell service for 3g and LTE are both good (green in battery stats). I know LTE requires more power however I would expect that power requirement to drop significantly when connected to WIFI networks which in my case doesnt seem to matter at all. At least now my battery life is awesome as others have reported. However connecting to 3g when away from home is a bummer and it's not really practical to manually change my preferred network every time I leave or enter a WIFI area. Looking at a way to automate this switch but on Android 5+ it seems that changing these settings via app are very locked down. I would also like to point out that my previous phones never seemed to suffer from this issue which only further makes me suspect that there is an unresolved underlying issue here (maybe related to the Band 4 issues being reported?). It sure is nice to open my battery stats window now and see some horizontal line segments instead of the linear march towards zero.
