In the story he states that the batter would last four hours? any truth to this? he also explained that there is lag in the sense?
http://techcrunch.com/2010/05/29/htc-evo-4g/
Maybe 4 hours of non-stop web browsing with the brightness all the way up while on 4G. Also, I've never had any lag with Sense.

The battery is is very poor. I'm not exactly sure why that's the case since the EVO doesn't report the screen as a large draw. For example, I unplug my EVO, connect my Bluetooth headset and listen to a podcast for 10 minutes. That drains the battery to 92% from a full charge.
You will most likely have to carry a spare battery to get through the day, with light usage.
I'm hoping its an optimization issue and they can fix the battery issue with an update. Fingers crossed.

hmm, alright i mean this is big for a person who is out 24-7. (arnt we all) i wonder if it has to do with anything similar to what the hero had when it was released.
My battery life is not perfect. But people always have this problem. I was a G1 owner and everyone complained about the battery life when it first came out. And then slowly after a mont or two everybody stopped...why? Because the battery life got better with time. From 5 hours or so to 9 or 10 hours.
Then I went to an HD2. The first week I was so scared I had made a huge mistake because the battery would last about 4 or 5 hours. After I did as suggested and let the battery completely burn out and then completely recharge for about three cycles, the HD2 had the best battery I had ever seen. i could use it for 2 days and have 60% left.
Now I have an Evo. And the first stay (with constant use) it died after about 4.5 hours. But I am going through the process of draining and then FULL recharge of 6-8 hours and I'm sure it will be fine.
People think they plug the phone in an hour or two and it says 100% and they have charged it. My opinion is that it takes the battery a while to know what 100% and 0% are on any given battery. After it cycles through a few times it will actually have a true accounting of the battery life, power consumption.
That is all my opinion and experience. I am hoping the EVO has a similar battery life to the HD2. That would be perfect for me.
EDIT: And as for lag....the guy is obviously on crack and just saying stuff to say stuff. I doubt he even has an EVO. He's reading about Sense Lag on the HD2 which there was some) and passing that information on. Anyone who actually HAS an evo have any lag? I think not.
And if he thinks an iPhone 3GS in ANY way blows the EVO out of the water...he is obviously lying. I mean based on feature set alone. There is no way the iphone can browse as fast (4G...hello), operate as fast (gee isn't that processor almost twice as fast), take better pictures? No. Have a front facing cam? No. Oh yeah...that screen size on the iPhone sure is better than the EVO. WTF?

I understand what you are saying. That was the only reason i am worried about buying an EVO. This author must have had all the applications syncing every 15 minutes. I have an apple itouch not sure how close the phone and this thing is but I like it. It is smooth and quick. (buts its not a phone). When it comes to android... Its about the experience that comes with it.
But this guy is positively being paid off haha

With light usage I had 36% remaining after 14 hours the other day. I think you just need to give the battery time to get adjusted. However, I have noticed that it seems to drain faster from 100-80% than it does from 80-50%.

Well I actually just recently noticed the same about my iPhone 3G. The first 10-15% go really fast.
My evo seems to do pretty good with the battery I can go the whole day without needing a charge but I do charge it when I get home. When I'm using it for games all day it drains pretty quick but at those time I plug it in... I don't know what they expect when your rocking a 1ghz processor, a 4.3 inch screen, and about every type of network connection you can fit in a phone... as far as lag goes on this phone I notice very little mainly when I'm installing like 3 or 4 apps at once... compared to my hero this thing is a rocket! And once Android 2.2 is put on here this thing will be smoking.

My Evo lasts for 8-9 hours. That's 70% idle with screen off. Cell Standby at 40+% is killing my battery.
My motorola droid in the same time still has over 50% charge. There's no question that the Evo is a battery drainer for whatever reason.
hate to say it, but once a fan boy always a fan boy. I used to have a win-mo device (touch pro) and i like it, then i moved up (should i say downgraded) to the instinct- worst decision ever. than i used the android platform on my hero. I'd have to say its leaps and bounds easier than win-mo.. My brother has an iPhone which i always play with when he comes over, and i think its a really easy interface to play with.. thats all. The speeds at which apps were open weren't any better than my hero. I also opened up maps on his phone and mine, and my location was dead on with the hero, the iPhone was 100meters. LOL.
But everyone needs to try other stuff out and make there own decisions, dont let someone who is obviously a fan boy tell you whats good and bad.

thats ur prob ur using bluetooth it will use more battery and then ur playing the podcast at the same time any phone u do that on u will use more battery
the battery technology is a few years old. the cpu is 1ghz.. the phone is sniffing 3g/4g/wifi/bt plus the shiny screen and backlight all use power. the battery technology being used in this state of the art phone is not advancing as fast as the phones are...
the reason the top ~10% of the charge goes so quickly is due to the you taking the phone off charge.. the cells in Li-ION batteries are not created equal. some cells will get a stronger/longer charge than other cells. once you take the battery off charge, the cells that are stronger in charge than the others will feed that extra charge to those other cells, so your battery charge will fall down to around 90 or so pretty quickly out the gate.. from there the cells are all stable and equally charged and stay at a constant discharge rate for about ~87% to about ~55%.
once the charge falls below 55% the cells really start to lose their charge and the battery curve drops drastically.
when you "top off" the phone for , say, 30 minutes or so and you take it off charge and you see 100%. do understand that one or two cells have a fuller (my word) charge than others.. once the cells equalize, then you will see the tru charge (which will be much much less than 100%)...
I'll post my findings here although probably no one will believe me. I'm not a fanboi since i've phones on three carriers.
My EVO will lose 2% per hour sitting idle which is fantastic. My HD2 loses approx. the same amount, maybe a little less.
I've found the EVO to be no more power hungry than any "superphone" i've used including the iphone 3gs.
signal strength also plays a part
one thought based on my experience with a palm pre and htc hero: signal strength.
My office has very low signal strength (1 bar or less). The battery seems to drain quite fast here. If I'm somewhere else with good signal, my battery lasts much longer. Same battery drain if you're going in and out of evdo / 1Rxx.
Sean
My battery life is like all the other phones i had lately (see my sig).
No more, no less.
I have to say my battery is getting better with going through a couple full charges, as for lag nope none not here
“Phone idle,” and “Android system” that eat up over 75% of the life.

LMAO, the fact that he wrote that puts severe doubt in his skills to review an android phone.
I can't believe this thread is going on seeing as that's an Apple Fanboy site. Will say anything to make his Iphone sound like the best thing ever. He lost all credibility when he said the Nexus One and Incredible were better phones.

the battery in the EVO (and pretty much every phone evar) is a single cell battery.
you have no idea what your talking about do you?
Hello all,
I hope I'm not beating a dead horse by asking this because I have searched this site as well as other places around the internet and there seems to be alot of information out there concerning how to charge your phone battery. But every time I read something, it seems to contradict the last thing I read. So I wanted to pose both viewpoints to the experts here in one place and hopefully get some clarification.
I recently got the Note 2 and am really happy with the phone. One of the biggest and most welcome surprises is the terrific battery life I have gotten so far. I am coming from a HTC Sensation and while I liked that phone, I always felt like the battery life pretty much sucked. When I first got the phone, it would barley get me through the waking hours of the day and that was only if I used it sparingly. Over the course of the nearly two years I had it, the battery life just got worse. I typically would leave my phone charging all night as well as in the car during the day if I had heavier use that day.
With the Note 2, I am seeing much better performance. I can easily make it through a whole day starting at 6am and by the time night comes still have over 50% charge remaining. I am not a heavy user but I have found myself using it more, trying to deplete the battery so I can charge it at night. My problem now is I can make it through one day with no problem but to make it through two full days may not work as well. I feel if I don't charge at night when its still around 50-45%, the next day I may need to charge right in the middle of the day when I need to use it or am not by a charger.
So my question is what is the best practice? Is it best to fully charge then fully discharge, and if so does it need to be a regular habit or just the first few cycles? Do I need to remove the phone from the charger once its fully charged or will an overnight charge be a safe option? If the phone is only at 40% or more is it ok to charge it? Are there any other battery management practices I should be aware of?
Thanks in advance for your help
dont read too much into battery charges...charge as you like...........at home, in car, connected to pc...........lol..........the battery will last for 2-3 yrs well...then if you feel it is dying, it has a removable battery.........you can always change the battery, buy a new one...they are cheap...
for ex:
you get ~1200 cycles if you charge from 40%-90%, but you will charge twice a day (2 charges a day will last ~400 days)
you get ~400 cycles if you charge from 10%-100%..charging 1 time a day will last ~400 days again

The above is the only proven effect on our batteries. The rest is handled by the battery itself.

Honestly ive always charged my phones however and whenever I liked. Overnight and at varying parcentages. Never noticed any battery degradation at all. My x10 battery seemed the same as the day I got it after 2 years.
I figure any detrimental effects will probably occur after 2 years of bad practice at which point most people would have a new phone anyway

How to smart charge the Galaxy Note 2 battery
The way you charge your device is very important and it can affect your battery life a lot. Charging it wrong will make it drain quickly and the battery will also last less, requiring a replacement after 1-2 years of use.
To smart charge the Galaxy Note 2, you have to only plug it in when the battery is below the 10% level and never unplug it until it is 100% charged.
You should also know that when your battery reaches 10%, it will last longer than usual. To understand better, it will drain much slower from 10% to 0% than from 20% to 10%. So don’t panic if your battery level is low, because it can hold for a very long time, especially in standby mode.
Never use low quality chargers, because they can damage your battery hand even the device. Only use original Galaxy Note 2 chargers and try not to use the USB cable for charging your device. Always charge it in the wall socket, because the USB port power fluctuates and can damage the battery. Also it will charge much slower.
Battery maintenance
Usually the battery is the first smartphone component that dies, having a lower lifecycle. Though you can prevent this by taking care of it.
The best way to prevent it from getting damaged is to avoid pulling it from its socket. The battery has some golden pins that can scratch or get dusty, so if you pull it out and back in multiple times you can damage the pins.
In order to help the battery work the way it should, always make sure to clean the pins with a soft cloth whenever you pull it out. This way you will keep dust away from them.
When buying a new Galaxy Note 2 battery, make sure to get an original one, as other might have a lower battery life and can have a shorter lifecycle.
Increase Galaxy Note battery life by disabling features
The Samsung Galaxy Note 2 N7100 comes with tons as features, like we just said at the beginning. But nearly all of them are big battery eaters and you need to be careful when activating them.
The CPU and display drain a lot of battery, so make sure to setup the display to turn off faster. Also don’t keep it turned on when you don’t need it.
3G and 4G are the biggest battery drainers on a smartphone. You should only keep the 3G or 4G network activated when you use the internet actively. If you really need a permanent internet connection, then go for 2G, though this eats your battery too. The best way is to only connect to the internet when you need it.
Do not keep the WiFi,Bluetooth and GPS activated when you don’t use them. They can drain your battery very fast even in idle mode, so make sure to disable them when you don’t need them anymore.
Live wallpapers are also big battery drainers. They consume a lot of CPU and RAM resources and also use your display more intensively. So you should never choose a live wallpaper. The most battery-friendly wallpaper is a dark one, which doesn’t use any CPU resources and also doesn’t requires the display to be very bright.
You also have to take care what apps you install and always look at Settings > battery to see who drains the most battery. There are some apps than run continuously and prevent your device from getting into “Deep Sleep.” This is the standby mode that helps the device conserve very much energy. If an app prevents it from getting into this mode, you will notice a very low battery life.
Please let us know if you found other ways to increase the Galaxy Note 2 battery life. We are also curious for how long did you manage to get your device running between charges.
wow thanks mate quite a good one!
Thanks!
Also you should add that if you always need to be connected to internet then its better to keep connected through WiFi as it consumes less energy than using EDGE or 3G.

Thanks it's useful
What?
No.
1. Deep charge cycles on a lithium battery accelerate the failure of the battery.
2. The device can determine the type of source it's plugged into, computer usb ports are safe.
3. Non branded chargers are safe if they are quality made. You just need to stick with quality and 2 amp/ short cables for decent charge times.
Sorry man, but those 3 things you listed are some pretty big misinformation that can easily be verified.
There's nothing "smart" about doing a deep discharge if your trying to preserve a 10 dollar battery.
After installing the new rom..I charge my battery full..then remove battery stats then drain full to zero for cycle.after complete ..I use smart charge method..that is .when my cell battery below to 10 something like 9 or 8 then I connect charger .and really it helps me alot

Deep charge cycles are for avoid "memory effect" and It apply to old Ni-Cd / Ni-MH batteries. Don't apply for modern Li-Ion battery. There is much more chance that the deep drain affect negatively the battery of a GN2.
Li-Ion battery keep better performance if never going less than 50%. But the difference will be barely noticeable.
Personally, after several tests on my own, I don't bother anymore with that (I mean for the modern Li-Ion type). Sometime you have a great battery, sometime a crappy one from a bad batch. I have seen battery died fast after "by the book" charges cycles. And others seem to last forever, no matter how bad I maintained her (like my 2006's laptop).
Anyway, thanks for sharing, even if you are wrong on this one
I don't know if you're wrong or right because when you search the net about battery charging, you find everything and it's opposite. But I disagree on three points:
- The battery is beefy and you really have to work hard to make it last less than a day
- I bought this incredible phone because of it's features. If I have to cut half of them to avoid drain, why did I buy it?
- I dare say that most of the people who buy a Note 2 somewhere are a bit "Tech-Nuts". If you're not, I am, so I don't mind if my battery doesn't last two years because I'm not sure that I will still have this phone all that long.
And if I do and the battery is dead, I'll buy a new, genuine, Sammy one to continue.
What's it worth to live 100 years if you can't have a drink from time to time, maybe have a smoke or whatever? Plug your phone in or out and use your GNote 2 happy
Lol everything has its cost turn off everything to save battery what is fun in that I have a smartphone to use it and be happy with animations and display and games otherwise get a 3310 it is best

So the battery life absolutely sucks on my One. If I start using it at 8am its dead by 5 pm. And that's just normal usage like surfing the web over WiFi, playing games (candy crush, dots, angry birds space,) maybe watching a few short videos over WiFi and the occasional text message. I have a battery saver app and I can see that it helps but I guess there's only so much it can do,Z so I want to get one of those cases that has an external battery built in. I have a few questions.
1. Does anyone here use one of these? Please give your input.
2. What's the best one? I've done a little research and found that the i-Blason and Mophie ones seem to be most popular. They're both a bit pricey.
3. How do they work? Does the phone just start directly using the external power after you switch it on, or does it just charge the internal battery?
4. Can these things have any kind of adverse effects on the internal battery from odd charging voltage or anything like that?
5. Do they actually extend your battery time as advertised? I'd be happy with getting two full days out of a single charge and some of these things are advertised as extending it by more that 1.5x. It seems like if the external battery is just charging the internal battery it would be a bit less efficient than if it were directly powering the phone. Does that make sense? It just seems like there couldn't possibly be a direct conversion of 2300 mAh from one battery to completely charge another 2300 mAh battery.
I hope that wasn't too confusing. Personally, I can't wait until lithium-sulfur batteries are in all our electronic devices (potentially 4x energy density.) Google it. Sounds promising.

1. I don't use these so I can't comment on this.
2. The iBlason and Mophie are the only ones available that I have ever seen. The Mophie being the higher quality (materials not necessarily battery life) of the two but also twice the price.
3. The phone will use the battery cases charge first then once that is drained use the phones internal battery. However if your phone battery isn't fully charged and you plug a charged case into it, it will charge the phone.
4. It's a good question and I'm not 100% sure. If you use it properly it shouldn't cause any major issues. Using it "properly" meaning your phone has full charge when it is paired with case so that the case isn't charging the phone. That being said, the damage is no different than someone constantly charging and discharging their phone in short bursts rather than using it until it's dead (or as close to possible) and then fully charging. The big thing to be aware of is that the damage caused is simply a reduced battery capacity and usually isn't big enough to notice during the life span of the phone (1 to 2 years).
5. Yes they do. Some of the claims may be a little higher than life experience, but nothing drastic. It litterally adds a second battery to your phone, so it IS going to extend the battery life quite noticeably.
One thing though, I have had my HTC One for a month or so now and have kept it stock, occassionally trying custom roms, but always going back. I have consistently been able to get over a full days use with WiFi always on, GPS always off, brightness always on auto, and I have exchange synced and set to push notifications. I am constantly checking email and texting for work as well as browsing the internet and Google Currents. I also have the power saver turned on. A full day use for me being from 8am to around 12am.
I think either something is wrong with your phone, you are playing too many games, or some setting or service is draining your battery. I would post your battery usage here for some to inspect. And it might be a good idea to uninstall the batter saver app, they usually don't make any huge dent on battery life that can't be done without the app, since most rely on a polling service that runs in the background and eat up battery life themselves. Just make sure your sync settings are reasonable (not every 5 minutes), turn off GPS and only turn it on when needed, don't turn on WiFi unless you need it, turn off 4G unless you need it (switch to CDMA only in mobile settings), enable eco mode (power saver that throttles CPU based on usage), and make sure brightness is set to auto or a medium to dim setting.

Mostly right. I'll toss out though that cases have different current outputs-- the mophie cases will output at a high enough rate to cause a phone to register as being on AC. the i-Blason case charges at about a third of that rate, meaning that it'll trickle charge your phone/reduce power consumption rate, but it won't outright charge unless you're not using it.

1. I've used one for about 2 days. I returned it. It works well and the Mophie definitely feels of high quality and feels great in hand. However it makes the sleek device very big and bulky.
2. I would recommend the Mophie purchased at your local corporate carrier store, reason being is that usually your carrier will offer a 1 yr warranty on a premium case like this. However if you break or it shows ridiculous wear and tear they wont. I cannot comment on I-Blason's warranty. Although I think the Mophie is perhaps more expensive. Some carrier offer discounts based on employer's of the account owner. So that might help get the case cheaper.

4. Usually since they're molded directly to fit your device, most manufacturer's will accommodate the OEM's requirements. But the Mophie charges as fast as it would if you had plugged it into an AC charger.
5. This question is a bit more confusing for me to answer. All I can say is that if they advertise a 100% charge then that means they're matching the mAh capacity of the device. (Ex. phone model has a 2000mAh battery internal and the case advertises 100%, then that means the external battery is also rated at 2000mAh.) So in reality if you're expecting a complete 100% charge while your device is still on, then no, you may get from 1% up to 70-90% depending on how much you're using it while its charging.

This is not entirely true. Because the Mophie has an on/off switch. So if the case is set to off, it'll use the internal battery first, then you need to switch the battery case to on to begin charging the internal battery. It is entirely possible to use the phone till it completely shuts down when it run out of juice and the Mophie have a full charge.
It uses the same charger as the phone itself so the case never has to come off, however even if the switch is set to off it'll charge both items at the same time.

I was not aware they had an on off switch, that would change the way the phone handles the device and give you a bit of flexability in how you use it, which is good.

I wonder if it would use the case battery first if you turned it on when both are 100% charged. Everywhere I've read, people seem to use them to charge the phone after the battery gets low. It would be great if the phone would just draw power from the case until it dies and flip over to the phone battery. I feel like that would keep the phone battery more healthy by avoiding inconsistent charging. If you're constantly killing the phone battery and using the case to recharge to less than 100%, then killing it again... it just seems like that would be bad for the battery.
Thanks everyone for the input! Keep it coming!

Good question. My thoughts would be that the phone would only draw enough to keep topped off. So I guess if the switch is left to the on position the whole time you would get the desired effect of draining the external pack first. But I would guess that doing that would reduce the efficiency of the case somehow.
In the end whether your constantly killing and charging your battery no matter to 90% or 100% with the case or A.C. charger, doing it more often will kill your battery either way. Given lithium ion batteries are way more forgiving than the old cadmium based ones that built up a memory of sorts.

To keep the battery healthy in a phone, make sure you charge to 100% each time. You don't need to fully drain battery, it's actually healthier to go from 50% to 100% than 1% to 100%.

So if my phone only gets down to about 40% each night before I plug it in to charge all night I'm ok? In the back of my head I'm always wondering if I need to drain it all the way sometime.

You are fine, it's better to not drain the battery all the time. It lasts longer if there's charge left. You just have to make sure your fully charging to 100% and not charging only to 70% or something like that. This is how lithium batteries work in all devices, laptops etc...

And either way you wouldn't notice the loss in capacity until you at least 2-3 years out.

So I've been thinking about this a lot over the past few days and I have something else i want to throw out there...
If you have your phone plugged in to a charger while at full charge, you can use it all you want and it will never go below %100. Does this mean that it's completely drawing power from the charger, or is it still drawing power from the battery, which is just constantly being topped off? Because I know I can completely remove the battery from my laptop and as long as it's plugged in to the charger, it will continue to function just fine.
If the phone is drawing 100% power from the charger, doesn't that mean that it would do the same for one of these battery extender cases?
Like I said before, I think that would be a lot more efficient that just using the case to recharge your phone's battery after it gets low. This way you sort of cut out the middle man.
BTW... I found that there was a weather app that I think was constantly trying to access my location even though I have location services turned off. I now get a good 10 hours of battery life with moderate usage. Still want a battery extender case. 2 full days would be awesome.
HTC battery life DOES suck compared what it can do because you are not going to buy a phone like this if you wont chat/text/call/email/play games alot. Mine lasts 10-15hours (usualy 2.5-3hours screen time and NEVER more than 3) and thats annoyng because its ok if im just ordinary home-work-home rezime but if i need to go out of the city for lets day 2-3 days - im screwed and allways must think about charging.
I have overlooked everything nothing wrong with the phone - the battery is just too small.
i keep wifi ,gps and bt off if i dont need them but my phone ofcourse syncs everything (thats the point of a smartphone - to be connected!) and i play often also.

Nope its being topped off, phones are all about maximizing space in the phone, it would require more wiring for the motherboard to be able to draw power directly from the micro usb port as well as the battery. For example, my Samsung phones can be plugged in but if I take the battery out the phone turns off.

I got this one - all day w/o charging w very heavy usage. Traveling w/o signal - 2-3 days no charge. Makes the phone bigger and you can't see the gorgeousness of the phone, but it protects it all around and it lets those 4 cores and crazy display to do its job w/o dying on you fast.
This guy sells them for $20. Have seen them in other sites for $70-130. Same exact model.

1. I have the i-Blason black.
As a Case
Pros: Great volume controls, Black matches the black HTC One and the black earbud plug, kickstand, central USB plug.
Cons: Thick, Gets Warn when plugged in
3. There's a button that turns charging from the case on or off. Phone will be like it's externally charging.
4. The i-Blason is a lower current charging, so there's a warning that pops up. I think it's not harmful.
5. Extends, yes. But >1 day, no. Well, if you're not using the phone, yes, > 1day. What I do is I let it charge the phone when I'm not near a usb plug and it gets < 80%, then i let it trickle back to 100% in about an hour. It automatically stops charging the phone at 100%.
Learn how to manage your phone guys. Track down the offenders instead of buying these battery packs and other nonsense.

What are you guys seeing in your first few days with your M9?
As for me, I can't remember any device I have ever owned that has had worse battery life than this M9. 3 hours of "light-slightly moderate" use brings me down to 75%. Very disappointing thus far.
definitely a downgrade from the M8 battery life. However once we are able install custom rom's and kernels ect. I expect it will improve.

Interesting. Compared to my de-bloated, undervolted, S-Off and custom ROM'ed (Adrenaline) M8, I am seeing similar battery life comparatively on my M9. I did disable a lot (if not all) of the Bloat on the M9, so not sure if that helps the cause.
Horrible. I have to charge my phone about after 5-6 hours of use. I work in IT so I know Exchange is hammering the battery, but on my M8, I could last 8-9 hours before charge. This is includes browsing /r/sysadmin and other reddits.
For some reason too, it seems the QuickCharge 2.0 is slower on the M9. On my M8, it was stupid quick.
My experience has been mostly positive with the M9. First, I disabled all the VZW bloatware and then let the battery run very low and fully charged it. I repeated this 3 more times over the weekend. I took my battery off the charger at 6:00 AM and with medium use, I still have 84% left. The M8 was slightly better when running GPE so it's not apples to apples, yet.

My usage and battery life is comparable to yours. After 9 hours of only texts and phone calls I'm down to 50%.
I honestly think its too early to tell. I've disabled most, if not all, of the bloatware and I'm seeing "decent" but not "great" battery life. The phone still has the "new phone vibe" though, so I'm likely picking it up more frequently than I normally would. I'm also coming from the m7 though, not the m8, so my expectations are probably different. Custom ROMs and kernels are definitely going to change this though.
Cores can be completely disabled in custom kernels, which will likely provide a big boost with little performance loss (how often do you really think all four of those high-performance cores are being utilized?). Likewise, tweaking max clock speeds, undervolting, and tweaking/changing the governor will likely help things a lot too. We're just too used to our old ROM'd phones. It definitely seems like we'll be able to squeeze much more battery life out of the m9.
After reading some of the replies I think I'll go through and disable everything I can since I only did that to a moderate degree before. I am hoping that once we get some optimized kernels and different features it will help. Also, full root access to Greenify could help, but so far it's a horror show.
Coming from a galaxy s3 and sad to say iPhone 5 the battery has been superior to those two.

My GSIII quadrupled what I'm getting on this M9. My galaxy s5 doubled it, easily. I'm just hoping it gets better.
Weird, I've been on it moderately all day and on 10% as of right now. Maybe I'm just used to horrible battery of the iphone

Feels about the same as my m8 maybe even a tad less honestly. Might just be from overuse running stock rom though.
Something with these new phones is killing the battery. I got the S6 and the battery is horrible as well, I can't even go a full day without recharging.
Every OS release Google talks about all these features that are supposed to improve battery life, but it only seems to make them worse.
Stock non rooted, disabled as much bloatware as I could. Haven't Set up any of my Tasker profiles (lack of root makes them useless for now) and I got a full 1day 5hrs before dropping below 15 percent. Battery life seems pretty much par for the course on a flagship phone. I also had an s6 edge for a couple of days but picking it up off the counter was a weird experience for me so I switched back to HTC. Aside from the heating problem which I believe will be resolved either by the community or HTC I love the phone.

The fact of the matter is yes, Google is making improvements in regards to battery life... but these improvements are offset and negated by consumer demand for faster, more powerful phones. The Snapdragon 810 is a beast of a mobile processor; its got two quad-core CPUs in it, so it definitely has to use some power to operate.
I can't wait to get a custom ROM my M9 and (hopefully) disable two of the A57 cores and see what happens (and see how performance is affected, if any).
I must say that I like it so much better than the SGS3! I can go a day and a half with out charging it... S3 was every day!
Even using GPS is less consuming... . Well worth the wait for HTC to get it right!
Other reasons that I like it better than the S3:
1. You can actually keep a grip on the M9!
2. The M9 is not as fragile!
3. Love the feel!
4. The audio is excellent (in my opinion better than any other available)!
5. The 3.5mm plug has a firm fit!
6. The charge port and audio port are both on the bottom!
I will stop there - I love this phone! (M9)
I'm literally sitting here with my phone plugged in, only with WiFi on and chrome browser, bloat disabled, screen on low, force closed most processes (ie play store, etc) and watching my battery % get lower... Plugged in!

Plugged into what, though? The 500mA maximum of the USB2 ports on your desktop/laptop is not enough to charge this phone with the screen on. You can slow-charge it at 500mA with the screen off, but it still takes some time. USB3 ports technically have a max draw of 900mA, which should be enough to slowly charge with the screen on, but in practice some laptops/motherboards won't allow any more than 500mA on their USB3 ports either. Use a wall charger for best results -- check the output rating though.
The included wall charger with the m9 is rated for [email protected] (1500mA). I'm not a fan of charging my devices extremely quickly, so I'll probably stick with the 1A (1000mA) charger that came with my m7.

Using included wall charger and cable.
Plugged it in this afternoon, turned off screen and walked away... in 2 hours it gained 2% from 47 to 49
Edit:
Very well could be faulty device. Using different cables/outlets in different rooms yields same results. M7 on same setup charges steadily during heavy use. Using m7 outlet now. Dropped from 17% to 14% while editing this post. Better screen off now so it doesn't die on me...
I usually wake up by watching a few youtube videos. This morning I woke up, grabbed my phone off the charger and watched a 16 minute video at 1080p with adaptive brightness (which was low). In the 16 minutes my battery went from 100% to 83%. That is atrocious. Hopefully new ROM's and kernels will be able to remedy this.
Also, the other day I was using a quick charger I got at Verizon with my phone and got the message I was using the phone too much to charge. I could understand if it was plugged into a USB port on my computer. How did I get this message while using a quick charger?
