Okay, a little back story. I've been a BB user for quite some time now, got bored and made the switch to N1 this past January.
At this point I'm ready to say: The N1 power consumption or battery BLOWS CHUNKS. But folks thats my take.
I mean here I am with the most powerful and best phone in the world right now and I have to keep my brightness at 33% (GOD forbid I forget and keep it at 100%, I wont make it through the day!). I have to keep my GPS off (so my geo tagging is always off by a few thousand freaking meters). I have to limit my use and take it easy on data intensive apps. It's ludicrous, I want to use this damn thing.
Don't get me wrong I'm fine with the 33% brightness and with the light use (because I'm a student and quite frankly I don't really push the phone like that, due to being in class). But I would still like it if the phone wasn't CRYING for the "milk" bottle every day sharply/promptly at 8 pm.
So the phone makes it through the day (hurrah). But it still annoys me that now I have this new "nag": "get home and charge me Ori". So if anything spontaneous pops up like say: a date with a nice young lady, you can bet your bottom dollar my phone won't be making it alive that night. It's another constraint on an already constrained enough life.
My buddy says "dude I don't know whats wrong with your idiot self.. blah blah blah.. my Nexus battery is great". But the damn jerk is coming from a G1 !!! go figure LOL...
When evaluating something you don't compare it to a pitiful performance. You see how you stack up against the best. So if you reached your conclusion because you are comparing it to a G1 or Cliq I have to honestly disagree with your method of reaching that conclusion.
PS. I'm not a nagging *****. I know I came off a BB. Thats why I'm not asking for much. I would just like to see the phone consistently make it to 11 PM every night from a 7AM 100% charge. Is that too much to ask for?
my battery never dips below 50%... of course i'm working most of the day instead of playing with my phone.
Seems about the same as my Nokia N95's was to be honest.
try the undervolted kernel, it saves you quite a bit of juice.
ill toss my input in on this after i run the att one for a few days to see how much running strictly on 2g actually saves, the tmo band one i had last a good 12-14 hours if i was playing with it mildly at work. thats with the check mark for 2g only, wireless is usually constantly on, and gps always on(but not always running up in the status bar), brightness set to auto
Not sure if there's whole lot you can do if you want to keep brightness at 100% and GPS chip on all the time.
I hike quite a bit and I use SportyPal to track my progress. Obviously when I hike, the screen is off but GPS chip is always on. Although I never managed to completely drain the battery so far, I would say it will last around 7-8 hours. I do use SetCPU so that when battery reaches below 40%, clock goes way down to the minimum possible.
Other than getting an extended battery, not sure if there is a solution. 100% screen brightness and GPS really taxes batteries on all cell phones.
By the way, this is MUCH MUCH better than HTC Magic (which in turn was much better than HTC Diamond). I'm not sure how they did it since the battery capacity is the same, screen is larger, and CPU is faster. I am happy.
Battery is better than the last few HTC devices I've used and on par with the TP2 (all had similar features, large touch screen, Wifi, GPS, BT). So I would say it's about par for the course as far as I am concerned.
Try the 3200mah battery from Seido... you can run all day with wifi, gps, and bluetooth plus have screen at 100% and still have 50%+ battery at 8pm.
If battery life is more important than the slim look, get the sedio 3200mAh battery.
With 0% brightness, occasional use (GMail, GVoice, GTalk), GPS and Sync on, about 20 minutes of talking, meebo IM running... The battery just lasts 12 hours. CPU profile set to 512MHz when below 50% battery; and is fixed at 245MHz when in standby/sleep.
For the amount of things that it can do I'm happy with the battery life.
If I'm going out I carry the AC cable in my coat pocket
I realize this may not be the best solution for most of you, but I also have a portable Duracell charger. It normally acts as a charger for 4 AA batteries. But I can plug-in a USB cable on the charger and the other end to N1. It gives me roughly another 2000mah worth of juice using 4 Eneloops. The charger is bulky though so no good if you want to carry them in pockets. But works for me when I carry a backpack with me. I needed this charger anyways for AA batteries so it's a nice bonus that it can provide some mobile juice for N1.
My battery life is pretty great. I'm running the latest Cyan with the EPE54B radio, i keep the screen on about 75% brightness and never change it, I leave wifi and gps on always, I have bluetooth on and connected for about 2 hours a day, for the 8 hours I'm at work I don't use my phone much only to send some txts and maybe use a couple apps. So I unplug my phone at 7am and when I leave work at 5pm I have 82% battery left everyday with my normal usage.
Just for reference; before switching to Cyan and the latest radio i would have 75% battery when I left work.
What are you people doing with your phones that you have to carry a charger or a spare battery with you?!
I'm coming from a HD2 and I easily get better battery life than half you guys even with heavy streaming radio/youtube usage and that thing has an enormous power-sucking screen!

Thread revival time !!!
OK so I discovered a few things that are worthy of mentioning since I last posted this issue.
My Nexus off/wake button crapped out and I sent it back for repair. When I got it back it was wiped (like new). I forgot to setup my facebook app and widget. For about 2 days I was going around with the facebook app "off" (it was finals week as such I was not paying much attention to facebook or distractions). I noticed better battery performance. Eventually I set it up but my "Sync Contacts" setting is set to "Don't Sync".
Also I got the SMODA widget that gives u direct "on-off" 3G capability. So whenever I'm at around 30% battery life I throttle the connection to squeeze out as much life as I can. Unless I'm browsing and I need 3G.
Good day to you all and enjoy the world cup.
In all honesty, I've been getting the best battery life I've ever had with Froyo. I only charge my phone in the car with the car dock to and from work (25 minute commute) and occassionally let it sit on the desk dock when I'm messing around online. With those charging habits, I typically get two days of use out of it and have no issues doing any of the things I need to do with it without a charger (games, navigation, calls, texts, web+market browsing, etc.). I could not say the same about any of the Cyanogen ROM's I was running before.
Hope that helps.
I have to admit...I am a bit bummed about the battery life. I have the stocked 2.1, on the ATT N1. I have turned off the brightness and I can get 3/4 of the day on the battery. I thought it would last all day but I definitely have to charge it by end of day.
I am looking forward to Froyo for, by all accounts, the battery life has been improved.
Again, I should emphasize that "I'm a BIT bummed" for all in all...I'm still loving my N1 and haven't looked back.
I've got Froyo on mine and this is what I've noticed.
If I turn my phone on, and send about 10 text messages in an hour, then turn it off, my battery life will be around: 94%.
If I let it idle for an hour without any action, my battery will drain about 1%/hr.
If I am using the internet and sms and just constantly using the processor on the phone, in abour an hr I'll be at 85% battery.
This is all with the backlight set at 11% (lowest setting it will go)
my battery last 27 hours on reg use... 17 hours on heavey use...
Pauls Froyo
3200 Bat
GPS always on
Brightness Auto
Listening to music alot on it to.
I find that on the ATT nexus one, setting to gsm auto (prl) makes a tremendous difference for idle time. With this setting I lost only 11 % in 12 hours of idle. And when I unplug, after 1 hour my battery will still be at 100% with no use.
This setting still gives you 3g too, so no worries.
My N1 on froyo started to hog alot of juice. I don't know why, it was fine the first 2 weeks but after that it started to suck up loads for some reason. Got tired of trying new kernels and i did many options so i gave up and went back to Cyanogen.. Running 5.0.8 Test5 with Froyo Kernel and it's about 20-24 hours since i last hooked it off the charger and it's at 56% left. Amazing. Tho' im a light user and i keep most stuff off when i don't use it. Even 3G.
I think that our perception of what we should get concerning battery life is a bit skewed. If I have RIM device (last was BB on metroPCS) I can go like two days without charing. All my email is push. There is no Facebook widget, or weather widget, etc constantly updating. The screen is half the size with weak resolution. The processor is half the speed, or less. The ram is barely enough to run the device. I could go on and on.
The fact is you have a computer, a small computer you can carry in your pocket. This machine is about as powerful as a desktop was 2 years ago. You are powering it with battery that is 1500mh and is the size of a dollar bill folded in half. What do you want exactly?
If you want a battery that lasts 2 or three days, get a dumb phone. If want a pocked PC, you are going to have to deal with the fact that doing all of the things your phone does uses battery power.
If I unplug my laptop I get 2hours and 15minutes. My phone lasts about 7-8hours. I stream music an hour or two, text, play some games, browse the web. I know that it is going to die. I have a spare battery. I change it if I can't charge it.
Battery life is worse than a Blackberry and better than iPhone, and you get the fastest device on the market. What more could you ask for?
So I think I have read that it is not good for the battery to leave it plugged in on a full charge. Last night I went to bed at 3 am on a 30% charged battery. I THOUGHT it was at 50% when I went to bed but looking at juice plotter I was wrong. At 8 am, according to juice plotter, the phone died. I missed my alarm and was late to work (my new job I have had for 2 weeks btw...doh!).
The screen was off and I have setCPU to underclock the CPU to 400 max 200 min when the screen is off. With the screen on and battery set to <80% the phone is underclocked to 800 max and 400 min. Basically the only time I have the CPU set to 1000 mhz is when it is plugged in.
Anywho, my question is this: Can I keep my phone plugged in while I am sleeping to insure this doesnt happen again without killing the longevity and usefulness of the battery? I know this time was mostly my fault with the battery being at only 30% when I went to bed, but I am trying to find a good balance between optimizing the battery and making sure this doesnt happen again.
Its how i charge mine every night for a month now. And no issues.
Have you paid for Juice Defender? If not i'd recommend it. I've spent the massive $4 for this app and like the rest of the customization for the power configuration. I used to leave my captivate on the charger all night but I don't anymore.. Not sure why your phone died on you, how do you have Juice Defender configured?
With a low battery level, you should charge your phone for anywhere from 8-12 hours. Battery indications are generally always incorrect. When your phone says it is at 100% after a few hours, that is incorrect. That is generally how it is for all electronics.
SetCPU has known issues with all SGS phones, Captivate included.
I had my phone depleted to 10 to 15% quite a few times now and I had no problem with charging. And I always leave my phone plugged in whenever I'm home.
You should be fine leaving the phone plugged in. The smart part of the charger is in the phone. You will get repeated charge complete notifications i think.

What's the benifit of the setCPU other than crash your phone ?
The biggest battery hog is always the screen display. If you're running stock JF6 ROM, it is well over 60% of the battery usage. Newer firmware does a better job controlling the screen brightness but still amount to 50% of the battery usage. The second biggest battery hog is 3G data transfer (or wifi data transfer if you primarily use wifi).
The saving from underclock the CPU will not be that much, IMO, other than make your phone feel slow I guess.

I permanently underclock to 800 mhz when using battery power. It still seems quite snappy to me.
If it is known to crash the SGS a lot, I will take it off. Guess I need to do some more research.
Any tips on how to handle the display?
Either flash to the newer beta firmware JH2/JH3 or manually dim the screen down. The automatic setting doesn't work well in JF6 firmware.

SetCPU is used to overclock, underclock, set different CPU throttling profiles. I don't think running setcpu is going to effect how fast your system is by running in the background, it uses like zero cpu cycles. My set up is currently the hybrid rom, setcpu oc to 100 to1.2 interactive and with the screen off 100 to 600 conservative. Ultimate juice defender set to turn wifi and 3g on only when certain apps are running that I picked, along with being one 1 min every 15. I'm getting about 36 hours a charge with average use, and I use about 1% an hour to every 2 hours in standby. My little juice defender score thing hovers around 2.33.
Setcpu does have good advantages, just learn how to set it.
I didn't mean setCPU itself use much CPU cycles, but rather by manually underclock the CPU to slow it down.
I see in your setup, you turn off the 3G data hence get better battery life. Unfortunately, it doesn't work for me. As I have 3 push email accounts: one Gmail, two Exchange Accounts which requires constant 3G connection.
If you leave the Juice Defender off, how much extra battery life do you get by under clock your CPU? One post I read that states once he removed SetCPU, his battery life actually improves.
Do you guys use JuiceDefender as an alternative to a Task Killer or side along with it? and does it work well with the captivate?
I keep myself plugged all night ALL the time and I'm also constantly on the phone from at least 12AM to 4AM while plugged in during that time. Haven't had problems so far.

Im patiently waiting for an official update. If it doesnt come by the end of my 30 days (which is 28 days away) at ATT, back the phone will go.
maybe something wrong with radio rom? (or how it is called)
If your phone stays in weak signal area a lot, that could kill your battery quick as well.

Yeah that happens to me, happened on my iPhones as well. My signal constantly switches between no signal, gprs, edge and 3G, it is never consistent and the searching just kills battery life. AT&T have been getting deluged with reports via the AT&T Mark the Spot app so hopefully they address the gap in coverage here soon!
Semi on-topic question. Is there a way to test battery health? I used to be able to get 36 hours on a single charge, and my phone was loaded with a ton of widgets and crap. Now I am lucky to get 12 hours and I have zero widgets, wifi always on, and a black lockscreen/background. Also running stock free juice defender.
Also, does anyone have an issue where they unplug their phone, and its already at 99% even after a full night of charging?
Is anyone else having bad battery life after the update? Cell Standby and Phone Idle used to draw most of the power before the update, now they're low on the list however Android OS is eating all the juice now. Android OS gets up to almost 70% usage overnight and the battery drains a good 30% or more just sitting idle for 6 hours.
I installed a program called watch dog and it's telling me that "Base System" seems to be the culprit with lots of CPU use, particularly when the phone is idle. I've tried a variety of things like uninstalling recent apps I downloaded, disabling the 4G and 3G radios, trying airplane mode, changing settings, etc. and nothing has made a difference. Really want to avoid trying resetting to factory default.
Have you tried recalibrating the battery or tried bump charging?
Sent from my SCH-I510 using XDA App
Since I use my nav dock in my truck to stream Pandora over my stereo, it gets charged several times a day; however, Android OS is now my big drain as well, where it used to be idle or screen using the most. Since unplugging exactly two hours ago, it has drained down to 70% on the stock battery. (I only use my extended battery when I will be away from a charger for a long time. Makes the phone too thick for my pocket to be comfortable.)
On a seperate note, Google Voice now hangs my screen as well when listening to voicemail. Hey, at least I don't get the random reboots and power ups... :what:
Sent from my Xoom using Tapatalk
I doubt calibrating will fix the issue because I don't think that's the problem. A system process appears to be hanging and causing the CPU to run constantly. Maybe a bad update install?
Either way I used to get much better battery life before the update. Never had any of the random reboots or many issues with data like others.
My battery life seems somewhat worse after the update. Everything else seems somewhat improved.
My battery seems about the same if not slightly better after the update.
I do a few things to conserve battery which really conserve the battery.
1. 4G off unless I need it.
2. Battery mode set to 'maximum battery saver'.
3. WiFi sleep policy: When screen turns off (although I think the maximum battery saver will turn it off automatically)
4. Display brightness: 0% unless I need it.
Before I bought the Vivid, I read every review that was out, even the customer reviews on AT&T's site. There was a common theme in all of them: Battery life is bad. Even the glowing reviews had "battery life" as a con or said they wished it was better.
Needless to say, my expectations weren't high. I have had HTC phones in the past and battery has never been their strong suit.
Imaging my surprise when I tell you that after a 10 hour work day, I go home with an average of 60% battery. I text throughout the day, have seven e-mail accounts syncing, widgets that pull data on my home screen, etc. I am definitely using the phone. I leave Wifi on all the time and I have LTE access wherever I go, so the LTE radio is always on.
Am I really that unique? Is anyone else getting good battery life with the Vivid? If the Skyrocket is supposed to have way better battery life, I can't imagine how long it would last compared to my Vivid, at least with my use.
Overall, very happy with this phone. Battery life is what always drove me away from Android and that is not an issue here.
I would say I unplug my phone around 7 and it gets to 10% around 7 so 12 hours ? I would say thats pretty good battery life I came from the inspire and it would die after 7-10 hours so I would say its a lot better! Though I cant wait for a cm9 or 7 rom since i was getting a full 24 hours + With that.... So im very excited to see!
I am also getting about 10 hours with heavy texting use throughout the day. I have friends overseas and we text via Whatsapp and sometimes Skype. Otherwise it would last even longer since I the screen display wouldn't always be on. I am not complaining getting 10 hours of use though since I'm coming from an HTC Aria which was about half that.
Almost as good
With the standard battery that came with the Vivid, I am getting 24-48 hours on a charge, but I don't use it as much as described above. I have WiFi on at work, but I don't do a lot of e-mailing from the phone. (I work at a desk all day, so I have e-mail on my PC.) But I do look up a lot of things. I suspect I use the phone for at least a few minutes 6-8 times during the work day and 2-3 times in the evening (with WiFi at home). I am not a heavy data plan user, partly because of WiFi access. I use Bluetooth to connect to my car's sound system during my 30-minute commutes. I usually put it into Airplane mode at night, cutting down on the battery consumption. So, I would expect to get somewhat better battery usage than someone who is on their phone much of the time.

Just out of curiosity: Why put it in airplane mode at night? Why not just plug it in to recharge?
I have a lot of days like you where I use it lightly. I have noticed that the idle drain on this phone isn't nearly as bad as past Android phones I have owned.
Yesterday I got 16 hours out of my phone. That is with me syncing three email accounts, running a live background, using data to read news articles, downloads from the android store, browsing the web, and making around 30 minutes of calls. It is much better than my cappy was. I made sure to charge the battery when I first got it all of the way before powering it on. I also have let it run down completely to cycle the battery.

When my phone was stock the battery life was OK, not terrible, but not great either. With a custom ROM the battery life has increased greatly. I unplug it around 8am and when I go to charge it at night I usually have around 40% left. That is with moderate to heavy use, at least that's what I consider my use.
Failed to mention I am on the stock Rom.

I got around 17 hours last night and was only down to 70% left. Quite a bit of use too. It's actually better for me than my GS2 was.

I'm always getting 20+ hrs on my vivid with med. Use with the stock Rom my battery was pretty good but with rumraider its going on about 30 hrs with 40% left ....wow and I haven't even charged it since I flashed
I think alot of the differences in battery life have to do with how strong of a cell signal you have. The weaker the signal, the quicker the battery dies since your phone is constantly trying to stay connected. Also, if your signal is bad, than that usually means your internet data is slower too and thus it takes longer to download news, email, and web pages, thus killing your battery even further.
Although, my signal is usually at 2-3 bars, the battery seems to last much longer than I was led to believe from reading reviews. Overall, I am pretty happy with this phone.
Just a suggestion, I am getting fairly good battery left, I am on a rooted stock rom with most of the bloat ware & processes frozen thru Ti Backup, I have wifi on all day but limit sync schedule (with refresh on use enabled) I have noticed that the battery stays at 100% for a while then starts to drop off. Today running about 7.5 hours and currently have 95% charge available. I also have Juice Defender free helping out with ballanced profile enabled.
Cheers

Simple rundown:
I text fairly frequently, do a reasonable amount of web browsing (read: where I don't have access to a computer), sync 3 email accounts, check XDA and play GameBoy on the thing. Weather is on hourly autoupdate with location; news is on demand when the widget is viewed.
The only daytime charging I do is when I'm using my phone as my car's AUX input, where it is plugged on the charger (although still draining according to the battery graph).
I end the day with 52% battery life, off the charger at 7:45 AM, back on at 12:00 AM. Much better than my Captivate. Prior to root, custom ROMs and SetCPU, it would clock in at around 38%.

I totally agree with this. My office is in the basement of our building and I get fairly poor signal - maybe 1 bar but I still can access the LTE network. When I turn my wifi on, by the end of the work day, my battery is much less drained vs not having it on and my phone searching for signal from the mobile data network.
At home, I have a pretty good signal, but there's not LTE coverage yet, so the battery does last longer throughout the day.
Even on the bad days I would get home and keep it running until I plug it in before I go to bed, so that's an average of about 17 hours in total per day that it's running on battery and on average I'd have like 30-40% battery left.
I was using an iPhone 4s before I bought the Vivid and I used to go home with about the same amount of battery after a full work day. Granted, the 4s gets worse battery life than the 4 by far, but I still think it's impressive that an Android phone, especially an HTC does this well and it makes me wonder why all of these people in the reviews have been getting such bad battery life.
It all depends on what it's relative to. When I had a BB, I'd go almost 5 days between charges, but there's no comparison between a BB and a 4.5" LCD screen.

This is a key point. The big screen is a huge battery sink. The battery widget in Beautiful Widgets gives a percentage battery use for components. With mine, the display's battery usage is always at least twice as big the next nearest battery sink. It is not uncommon to see that it is using 90% of the juice. I think this explains a lot of the early complaints about battery life. We all spend hours playing with a new phone and getting it set up to our liking. That means the display is lit up for hours. That means people get lousy battery life when they first get their phone.

I was trying to see how long I could go on a single charge. Airplane mode shut down radios that might otherwise continue to run, trying to pull data I would not see while asleep. Also, I would occasionally run the battery all the way down before recharging. I generally plug it in at work, in my car or at home when it gets down around 10% remaining.
Just as the title says is the power saver options like CPU and data connection really useful as well as the "sleep mode" option in power settings or are they making battery life worse?
If they are power savings options i don't see any reason why it would drain even more?

well according to this quote from another thread on xda in the sprint htc one forum,so I wasn't sure because it says it does make it worse.
"Power Saver mode will not save you any remarkable amount of battery unless you are maxing out the CPU or GPU (like playing games). Since what it does under the cover (besides what it advertises in the options) is downclock the CPU, this can actually be a detriment to battery life. It is better for battery life for the CPU to run at max speed for very short periods, and then go to sleep. It uses more power by running slower (and thus staying awake longer)."

Anyone?
I keep the power saver on most of the time. The main things I notice is that it dims the display (not really an issue if you work indoors) and it disables the wifi and data connections after periods of inactivity.
No real downsides (I'd be curious to hear other people's experiences). Sometimes receiving WhatsApp messages takes a couple extra minutes if the data/wifi connection goes to sleep.
Seems to give me good battery life - I average 15-18 hours, and that's including a fair amount of on-screen time and music/podcasts during the day.
I used power saver quite a bit in the 2 months after I got the phone but I don't use it anymore. In my experience it helped very little (as in added an hour or 2 maybe to overall life per charge). My baseline average battery life is 21hrs GSam tells me, and that's without power saver on at all (wifi, nfc, cellular always on and screen at 100%) and about 3hrs screen on time.
It may just be that, as was mentioned above, my use doesn't utilize the benefits of power saver because I don't often do cpu intensive things. It did run a bit cooler though. I also prevented the mode from diming the screen. I always (and still do) found that most of my power was going to the system (apps etc) @80% even with the screen maxed, and that I would lose about 20% overnight with our without power saver. So I stopped using it because : 1. It didn't improve MY USE 2. I didn't like the notification icon 3. I hear really good things about Battery Guru from experienced XDAers and the app seems more intelligent than power saver to me so I use that now. Unfortunately it's still too early to tell how much this will increase my average usage.
Regarding the issue of damaging your battery, the way it was brought up refers to the number of charge - discharge cycles a battery has. So only something that discharges the battery more quickly (so that you have to do another charge cycle more quickly) will shorten the battery's life. If nothing else, logically using power saver would not do this. It won't hurt the battery and may not hurt your usage (remember the GPU can still run at full clock for games), but I don't think it will help you much either based on my experience.

dont believe everything you see online. All it does it limit the CPU, as opposed to running 1700mhz, its capped at 1134mhz, this is not detrimental.
it takes power to make power, undervolting and downclocking processors has been repeatedly proven to assist and aid battery life.
it takes a certain balance or the two to get great results. Mind you the stock kernel is great but its adaptive. So dont be discouraged when seeing bad battery life initially.
If I leave my phone off charge overnight, I usually loose around 5%. If I turn powersaver on, I only loose 1-2%. This is with around 8-10 hours of no usage, with wifi on. It also turns off vibration feedback when using the back and home keys.
I've also noticed the phone to be slightly less responsive with power saver on. As far as I can tell, if you are concerned whether your battery will last you the few more hours you need, it will definitely help save power
It makes a difference and if you need the extra juice it will help you.
However, the amount of difference depends on your use.
If I am using Snapdragon Battery Guru should I deactivate Power Saver? Is the Power Saver a better/worse solution or a complementary one for optimising battery life?

Theoretically they should work together fine because Battery Guru studies what you do with your phone so that it can figure out what to prioritize and what to shut down - it adapts so it should adapt to the power saver situation. Underclocking the cpu shouldn't change what services it adjusts because you're still doing all the same things.
Battery Guru just finished "learning" on my phone yesterday so I don't know how good it is. But I lost 40% overnight for some reason which has never happened before. It's probably still adapting. Life seems to be better during use...
The comment above about the OS being adaptive is also very true, my first few charge cycles were dismal but they got better within a week (without power saver etc.)

Ya I'm using Juice Defender Plus on my HTC one running 4.1.2 for a few months now and I'm not sure if it's making too much of difference. Are you finding Battery Curu pretty decent?
I turned it off on my wife's HTC One. It was disabling data/wifi after several minutes inactivity, which caused FB Messenger to freak out and stay awake, which caused the battery to drain faster than if the data was just left on.

Hmm... If I leave my phone off the charger overnight after a full charge with power saver with WiFi on for 6 hours it will be down to 95% with no usage.

Sorry still to early to tell really, it's learning period ended yesterday so it'll take time for GSam to find the new average usage. But again it SEEMS to have improved drain during use. I'm really not sure what the drain last night was but if it happens again tonight the app is gone...

I used to have a higher drain, but after some research, I found out using betterbatterystats that google maps was waking up the phone often and preventing sleep. I corrected this by disabling "report from this device" in google maps settings.
Before this, I experienced similar battery drain with power saver on.
From experience, it's best to determine phone sleep time and app battery usage, and correct this to achieve the best life.
I'm currently able to get two days with light usage without power saver!

I changed my mind, I'm consistently losing 40% per night after Battery Guru activated. I can't confirm that this app is the problem, but it's never happened before and I haven't changed anything but adding the app. Maybe just me experience though.

I've uninstalled BatteryGuru for the same reason
I'm relatively certain that for many people this is super old news, but I'd like to share this anyway just in case it helps anyone (and a bit because I'm just so impressed by how it works )
I've tried a few different power saving strategies on this phone and have been disappointed with all, including just keeping power saver on all the time. I would always lose 20-40% overnight no matter what I did. I should also clarify that it is not acceptable for me to just disable a bunch of things to get that drain under control. So one day I turned on power saver (everything checked off) and just turned off wifi, and I've been doing it ever since because now I only lose 5-10% over night maybe a strange thing to be excited about considering my other devices lose as little as 1% in that time with nothing turned off, but everything's relative.
I think now I'll try keeping wifi off and power saver on throughout the day and see what I get. Though I'm not sure I like the thought of data being turned off during the day when the screen isn't on...
For me at least this is the single best battery saving thing I've ever done on my One.

What you mean by saying that you "turned on power saver (everything checked off)"? What Power Saver does if everything is checked off? I suppose like that it actually doing nothing. If you uncheck everything and turn it on isn't the same as turning Power Saver off?
