I absolutely love everything about my first Android phone, the hardware, software, apps...it's all good...except the battery life. I've tried most everything I've read here to try and maximize it, and I'm still having to break out the charger to get me through the evening.
Coming from BlackBerry, I've been used to having battery life exceeding two days...not that I ever needed to last that long, I always charge each night anyways. I merely want to be able to make it to bedtime each night without having to charge the phone, without having to cripple the features I love about it, and without having to be overly wary of my usage.
Is this dream possible with this, or any Android device?
I've tried the stock ROM, now on UnNamed...tried Juice Defender (got rid of it), SetCPU, Screebl, using Llama to shut off wireless when away from home or work, brightness down low (shame with such a beautiful screen)...and I still average around 7% an hour drain. CPUspy tells me I spend 60% of the time in deep sleep and 15% at 200mhz.
I don't really know what else to try, I want so badly to keep this phone, but don't want to significantly compromise the way I'm used to using my mobile device. I don't play games, I don't watch videos, I use my phone as an information and communications tool...and from that standpoint, this phone is simply awesome, if it would just get me through the day.
I have one week left to try and resolve this...what should be my next step?
It does sound like you're having unusual low battery life, my phone says that it's been 2 days 6 hours since my last charge and I'm still at 30%. If I were you, I would go and try to exchange it and see if maybe they give a little extra time to test out the phone.
See I would be ecstatic with 30% remaining after just one full day...I take the phone off the charger at around 7am, and would prefer not to put it back on a charge until 11pm or later.
I got it from Amazon Wireless, so I'll have to give them a call and see what they say about an exchange...you always run the risk of getting a device with an issue though, and this one is perfect otherwise...
Best of luck resolving this man!
It seems that the drain is only really happening when the screen is on...I can let it sit for awhile, and the battery meter doesn't budge...but I pick it up and start using it and you can practically watch it dropping...
Turn your data off when you're not using it

So from about 7:30 this morning until around 12:45pm, I dropped about 13%...which is around 2.5% an hour, something I can live with. Although that was with almost no use, screen off most of the time. In the last 45 minutes, I've been using the phone, reading emails, screen on much more, and it's dropped 8% more in just that 45 min period. My screen brightness is about 25%.
That can't be normal, right?
EDIT: Ya know, I'm just going to shut my mouth and enjoy my phone. I put it on the charger at work for the last 30 minutes of my workday today, and I'm at 80% at 8pm...I'm good with that. I'll pick up a couple spare batteries, and with chargers at work and home, I'm all good. I'll keep it as bright as I want it, sync data as often as I want, leave the CPU speed alone, and quit looking at the battery gauge...when I do that, it's a fricken awesome phone.
I was having this problem also, I use juice defender pro, and setcpu. I have juice set up to kill all connections when the phone is sleeping and set it up to where it syncs my facebook/emails every 2hrs, in setcpu you can create custom profiles that allow you to underclock your cpu when its sleeping, charging, certain times of the day/night. Im looking at my phone now and im at 1 day 0h 16 minutes with over half left. If you need some help setting up custom profiles and configuring juice (I recommend redownloading it again.) Shoot me a pm and ill see if I can help you. Good luck
I didn't want to compromise how I use my phone either. Most days I take my phone off the charger at about 7:30. By about the time I come back from lunch 1ish, it usually above 50%, but right around there. I generally plug it in at work for a few hours and generally can get it back to 90+ before going home. The day includes generally 3-4 hours pandora, so I figure that's par for the course. When I had my captivate doing the same thing it was almost dead by noon.
I think I might just be able to make it all day on a singles charge with what I consider heavy use, but its nice never seeing my battery drop below 40. Here's my weekly use, you can see the pattern of small drain, recharge, drain, charge overnight.

Everytime I think my battery is draining too fast I think back to how long ago the power in my hands wasn't in a computer tower, and I calm down. My phone is an extension of my hand, always being used, I don't expect my friend to starve, and don't feel unreasonable to let him snack mid-day.
For what its worth I am on UnNamed. I used S8 and did not see the giant jump in battery a lot of people claimed, I felt it was the same. I wasn't on stock long enough to really tell. But, I feel you need a week or more to really know, and I didn't last that long on stock.

What is your screen timeout set at? Anything more than 30 seconds will drain battery excessively. Also, do you keep your screen on when listening to Pandora, or while charging the phone? Those are also a waste of battery.
2.5% per hour when idle its not bad, and losing 8% in 45 minutes with the display on is actually pretty good...
I leave the screen timeout on 1 minute, its too frustrating to me when I am trying to read a webpage or thread and it times out. Maybe I am a slow reader, LOL. 45 seconds would probably work for me, but its not an option in these ROMs. I leave my screen brightness to automatic, and turn off my screen as soon as I start pandora. I do use Bluetooth to listen to pandora, so I bet that doesn't help. I also listen to audiobooks over Bluetooth in the car to and from work. But I did all the same stuff with my captivate. I have started using wifi when at home, but haven't seen a battery impact for that.

not surprising at all to see your battery drain like that when you use bluetooth so extensively. nothing wrong with bluetooth, but it is definitely going to use up your battery faster - there is a huge difference in battery drain between a regular voice call made with the handset, and a voice call of the same amount of time made in my car via bluetooth - i don't have exact statistics, but i'd say about double the drain. same thing between a wireless bluetooth headset, and a pair of wired headphones.
sounds like you have solved your problem with multiple chargers, but if you wanted to avoid charging in the middle of the day, switching to a wired pair of headphones when listening to all of your pandora would almost certainly do the trick.
Wow, I didn't realize it was so much. I have headphones in my desk at work for computer trainings, but never use them on my phone. Plus I could plug my phone into my car's radio go play over the speakers. I think its a convienience thing more than anything else, not having to unplug for the car when I get to work, nit taking the headphones out to pick up something at the printer.
As you said another charger is a good fix, something I never need on weekends, but I ways attributed that to pandora more than Bluetooth. Definately food for thought. Thanks.

As far as the screen timeout, I use Screebl and it works great. It senses the position of the phone to know when it's being used and keeps the screen on, then also can tell when the phone has been set down and turns the screen off within seconds. You can manually set the angles and positions so it also works fine when you're reading in bed. Helps with both keeping the screen on for those long emails as well as shutting it down quickly to save a little battery life.
Without a doubt, it's the screen being on that is the primary battery killer on my phone...when it sits idle, regardless of how often data is being used, I'm under 2% per hour drain. When the screen is on, you can practically watch the needle go down, it's crazy.
I do use SetCPU to drop the CPU to 200-500mhz when the screen is off, and to drop to 200-800 when it gets below 30%...aside from that, I'm done trying to optimize. I want to have my email and other notifications come in when they were sent, not an hour or two later. I want to see the great screen in the daylight, not a dimmed version. This is why I bought the phone. All that power requires some juice, so I'm going to make sure I've got extra juice on tap.

What is that app you're using?
The SGS II has power drain issues as well? I had the captivate and I could turn it on and watch the battery drain. I'm on Atrix 2 right now and I have zero issues with the battery. Best buy has dropped the price of the SGS II and it's really tempting to switch. Hmm what to do... What to do...
I picked up an Atrix 2 from Best Buy off contract last weekend so I could compare side-by-side with my SGS2, I really wanted the notification LED...but I took the A2 back yesterday. Improved battery life and the weak notification LED couldn't overcome the stark disadvantage in performance and screen quality (in my opinion). Laggy web browser and menu scrolling in comparison and an overly backlit looking screen with little contrast...although if I hadn't already had a couple weeks with the SGS2, I'd have probably been fine with it.
Everyone has different experiences with battery life depending on how they use their phone, you should grab the SGS2 and do a comparison and see what works best for you. Battery life has dropped down my priority list as of late, since I'm using the phone so much more now for every little thing (becasue it's so damn gorgeous), I have to expect to use up some juice.
Yeah I had to install miren browser, go Launcher, and handecnt SMS to change the color of the LED colors. Loving the phone and hopefully we will get an unlocked boot loader. SGS was really easy to root, flash, and OC. Still a bit pissed at AT&T for releasing another SGS II, no reason for doing that. I have a couple of weeks to kick the thought around. If its looking bleak for us A2 users then I'll jump on over to the OG SGS II lol. Screw the skypocketrocketshipboat.

First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

or maybe not
Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:
Callpod Fueltank Duo
http://palmtops.about.com/od/accessoriesperipherials/fr/Callpod-Fueltank-Duo-Review.htm
Mugen Extended-size High-capacity 2600mAh Battery for HTC HD2
http://www.mugenpowerbatteries.com/
There is a 15% discount right now, better hurry.
Extra chargers and thats it! Now I browse, calls, emails, music, videos, TV stream (Slingplayer) and maximize all of the other features of my HD2 t9193.
Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.
http://forum.xda-developers.com/showthread.php?t=718173

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?
As the title says I haven't seen anyone actually test the battery for a couple days, it's usually review and move on.
So how is it?
Well it hasn't been mentioned so it probably isn't worse than we expect it to be.
Also interested to know. Of course since this will be the first few days people have it, they'll be using it a ton so it may not be the best estimate on battery life but I would love to know an idea of how much to expect.
They haven't had time to calabrate yet.

7 hours of heavy use isn't bad. So idling with 4G off probably isn't terrible then. That is what I am most concerned about. Hopefully we will get kernel source and just get some undervolt going.

yeah not to mention that after you root you can flash leaner kernels and ROM's. But we'll have to wait for development to pick up, I really hope we see some good developers here.
So right now it's 1am and I took the phone off of the charger at 8:21 with 85% battery life. It is now at 47% with some steady texting, exchange activesync, some web browsing, and a 7 minute video all on 4g. I'm not sure what to make of that but it seems decent.

DAMMIT I WANT!!! 3 more days...
I don't know that I've charged it fully since I got it. It was close to fully charged before I went to a wedding tonight. Lasted all 6 hours or so I was there, but was tuckering out (~20%) by the time I left. But I did spend a bit of time playing with the phone. And 4G was on the whole time. And I turned live wallpaper on, played with my weather and clock widgets, tried to get a wifi connection that wouldn't work, browsed the web a bit.
I recharged on the way home to about 50%, and sitting around playing with it for the last hour to 1.5 hours, it's still at 40%.
If it makes you feel any better, the biggest battery hog was the display, BY FAR. Like 80-something percent to the <20% combined for the other functions. I'll try and remember to post my impressions from my first "normal" day of use tomorrow and let you know how the battery fairs.

I got mine yesterday and I can say it is about 25-30% better than a rooted thunderbolt....My logic says once rooted we will get really good battery life.
I am a heavy user and I can say I turned off fast boot and bump charged it 3 times on Thursday night. I gave it a heavy use all day on Friday.
Took it off the charger at 10 am around 8 pm I was on 35%. So that was 10 hours of heavy use and still had 35% left. If I was using the rooted bolt I would have been dead around 5:30 and a stock bolt...even sooner.
hope all these battery estimates are true, sounds like this will be my next phone!
Took it off the charger at about 11am today... Was close to 100%, maybe 95%. Just hooked it up to charge about 10 minutes ago (so off charger completely for ~10 hours). It had ~10% battery life left when I hooked it up.
Had Wifi and/or 4G on the entire day, including an hour and a half in a bad service area, where it fought for a bit to find service until I logged into the wifi network. Played about 1 hour worth of Pandora on high quality setting. A couple minutes of 4G Youtube. Tons of tinkering with games and downloading apps and playing around. Screen brightness was set to something like 30%. live wallpaper enabled. Weather and clock widget enabled. Data tracking widget enabled. Did a few seconds of video Skype too. I would say it was consistent use all day, but not necessarily heavy for most of the day.
EDIT: I forgot. One short phone call. I'm sort of a bad guinea pig for battery life on a phone because I really don't make a lot of phone calls. Consider my use representative of someone who uses data during his commute and for texting/games/forum/app usage.

Bad/No service areas will kill a battery so fast. My office is in a windowless reinforced concrete room inside a reinforced windowless room inside a reinforced building. (Yo dawg)
I get no service at all. If I leave the 3g on, phone won't make it past 5 hours. Turn the 3G/WiFi off and battery percent goes down a few points.
I need one!!!
Kellex over a Droid-Life has gotten just over 10 hours of normal usage (all in 4G) for the past couple of days. He also stated he is not a heavy user by any means.

Seems like it isn't as bad as most thought it would be.
Battery - Caution
I remain interested in the phone but undecided due to some really bad hardware failures I have on my Dinc.
While I am very interested in battery life like everyone else, please everyone keep in mind that "how is the battery" is as personal a question as "which radio is the best one to use."
There is no way one person can truly tell you how the battery will be for you. If you sit in an interior office without wifi, and have sync contacts and facebook set for every hour, that ALONE will cause a drain that may not be comparable.

Yay, you got another post!
That aside ... just please everyone keep that in mind when making battery life decisions based on what others experience; battery life can be GREATLY impacted by things well outside what programs you might run and how many texts you might send.

Do you notice the difference in the 2? Like does the qcell with 300mah more make a difference?
I have one; started using it yesterday. Haven't used it enough to notice a difference, but personally I doubt there is one. If it was so easy to fit 300mah (>10%!) extra capacity into a battery, why wouldn't Samsung have done it in the first place? Surely a 2800mah battery would be a better selling point than 2500mah.
I miss that battery testing web site where the guy stress-tested all the aftermarket batteries and showed how basically all of them were massively over-rated.
I have two OEM batteries (got one as part of the awesome Samsung portable battery charger) and I figured for $15 or so the Q-cell was worth trying. One of these days I'll do a run-down test and see if there's a difference. If there is, I'll buy 10 of them and then report back here how great they are.
I *love* this product:

It doesn't charge the phone, but you can toss it in a bag, swap batteries mid-day and have enough juice to get through a long evening of speed tests and server management while out on the town.
I've never had a phone die on me mid day.
I've never had hypothermia. Doesn't mean I don't carry a jacket when it's cold out.
My point is that for me, by mid-day my Note is often in the 30-40% range, and if I want to comfortably go for 8-10 more hours it's nice to have a fresh battery so you don't have to think twice about it. It's one thing to be at 5% and getting critical battery warnings at 10pm when you're home on the sofa. It's another to be getting 5% battery warnings when you're out somewhere far from a charger and need to use the phone.

Mid day its that low? I go through my whole day and by the time I go to bed at 12 its at 40-60%.
Yes. I have 3 email accounts - 1 exchange and 2 IMAP (even though I set the intervals for IMAP to 1 and 2 hours), and I use the phone as a desktop replacement for answering emails, server management, and various other web-intensive functions. I lose 10-20% per hour while in use. Screen on auto brightness. Bluetooth is always on because I use a headset or a car link for voice calls, though I don't make a lot of voice calls. If I did my battery would be dead by noon every day. On voice calls my battery graph drops precipitously.
I am in a fringe LTE area, which I suspect doesn't help. Sometimes I get 1-2 bars of LTE, and most of the time I get 4 bars of non-LTE. Searching for signal and switching back and forth is probably not good for battery. Either that it's the time that it's on LTE that kills it. So I'm resigned to either swapping batteries mid-day or leaving the phone on a charger at various times throughout the day.
Back to the Q-cell battery, tomorrow I will use my other phone for the day and try to run a couple of video loop tests with the Q-cell battery and the OEM battery and see how long each lasts.
Thanks looking forward to the results.

Planning on it...Monday is looking good as ill have some uninterrupted time where the Note can sit on my desk playing movies. I want to run them down as quickly as possible, so I'm planning to turn wifi on, brightness full, fullscreen movie mode. I don't know if running maps in the background or maybe GPS status would help too. Open to suggestions.

Thanks...I'll look into those but I figure full brightness video is fine too.

Test 1 is currently running. Fully charged Qcell 2800, started at 6:45am; as of approx. 9am (2h 12m of full screen video with GPS status running in the background) battery was 65%. I have the phone in flight mode to remove network connectivity/signal strength as a variable. Full results will be in tonight.
Well this isn't even close. I'm half tempted not to bother finishing the test. On test #2, OEM battery, after 2h 12m of video the OEM battery is at 78%. 78% vs 65%....that is HUGE. The OEM is winning by a mile. But for kicks I'll finish the test and post all the results/graphs.
"2800mAh" battery is more like 1600mAh
The results are much worse than I expected. And I notice that Amazon isn't even selling these batteries anymore, so that's something to take note of. I would imagine the data below would look familiar for any aftermarket battery sold at a cheap price (and possibly some sold for a not-cheap price).
Each battery was charged to 100% to start. I used the Samsung video player on full brightness (using the video player setting, not just the Android setting since the video player setting overrides the system). I played 3 movies on the Note during the rundown tests, in the same order. Mostly the Note sat on a corner of my desk playing with volume off; occasionally I stopped it to take a measurement or screenshot.
The "2800" battery lasted 5h 32m to 1% charge. Discharge rate was fairly linear, though it did accelerate a bit starting at about 25%. After movie 1 (2h 12m) it was at 65%, after movie 2 (4h 15m cumulative) it was 30%, and did not make it through movie #3.
The OEM battery lasted 9h 35m to 1% charge. Discharge rate was also linear and remained essentially the same from 100 to 0. After movie 1 (2h 12m) it was 78%, after movie 2 (4h 15m) it was 57%, after movie 3 (6h cumulative) it was 36% (the "2800" battery died during movie 3), and after movie 3 I went back and played movie 1 again (in full) and then started movie 1 AGAIN and got another ~90 minutes into it.
The difference is ridiculous. Since the "2800" battery was only $14, price per mAh is actually better than the OEM battery which is more than twice as expensive, but this thing is more like 1600mAh than 2800mAh. This isn't surprising to me, but it is good to quantify how terrible these knockoff batteries are. If I'd paid $20 or more for it I'd be angry, but given how cheap it was I'll toss it in the drawer and know I have a cheap 5-hour battery in addition to my two OEM batteries.
Since the "2800" battery has only had a couple of charge cycles, I will try to run the test again in a few days and see if more charge/discharge cycles make a difference. My OEM batteries haven't had many more, though, since I have two and I've been swapping between them on alternate days. I don't expect to gain 1200mAh.
Notice something else. When I rebooted for the 2nd test, bluetooth turned itself back on despite the Note staying in flight mode. I didn't notice that during the test, but that means that the OEM battery was actually under more load than the "2800" battery for the 9+ hour run.

please report back !
So after using them for a few days, they actually seem pretty good.
I don't think I have the patience that Hausman (I actually want to call him 'haus) to do a more technical burn analysis (thanks 'Haus). Plus, I'm lazy. However, I've been using them instead of the Samsung OEM battery for the past few days and they seem to be transparent enough that I don't notice that a different battery is being used.
For $30 on Amazon, I'd tap that.
I know this topic is always repeated but I fly I should havr made a thread anyway. This morning, in 15 minutes of web browsing, I lost 3% battery. In 10 minutes, I lost 2%, so it seems to be progressive. I just got this phone Friday.
That can't be normal, is it? I don't want to return it but I will if its a bartery issue. Could it be as simple as buying a new battery?

Most people report good battery stats. Give it a week and see if it settles down. Might need a few recharge cycles to level out.
As mentioned, the OS needs a few power cycles to generate its Batt Stats to give you a more accurate baseline. Also if you need your device to last all day and into the evening with no supplimental charging, you may want to look into taking certain measures to ensure your battery life is sipped and not gulped. I am not sure your level of experience or you tech knowledge, but basically anything having to do with comms is going to suck life. BT, wifi, 2g/3g/4g, and gps are what we’re talking about. You can manage these manually or use apps to do it for you such as Juice Defender and 3gWatchdog to name a couple. My office is in the bowels of the building where reception is spotty. The first week with this phone, my battery was at 40% by lunch time. This is because it was constantly searching for signal and when it did get one, it was being forced to high power to maintain it. Since I really don’t use my handset much in my office, I decided to take drastic measures to see what could be done. I installed the previous mentioned software already to keep my data use under control (came from a unlimited plan sucking down 8-12 gigs/mon on average) so with a few tweaks it was set to assist me. So when roaming my building I check it occasionally and when in my office I switch to airplane mode since I have my email in front of me and I use Google Voice to ensure all my calls find me no matter where I’m at. I arrive at work at 0700 and stay charged in on my drive to work. So at 0700 I was at 100%. I switched to AP mode after 15 minutes of typical goodmorning watercooler talk. At 1200 I looked at my Note and it read 99%. I went to lunch and opened all connections up while in our cafateria and after 45 minutes I was down 5% with comms going and lots of email and FB browsing. I’m back in my office and still at 95%. Obviously not everybody can follow the scheduled use as I laid out, but it works for me since I don’t have signal anyways and will make day much easier when I have to do lots of running and wont be plugging in untill tonight around 2300 except when commuting. I’m hoping this trend of juice sipping continues on for the rest of the day.
Screen brightness\use also is a big juice sucker. So, with the big screen on the note you need to be mindful of that, too.
Thank you for taking your time on that long informative answer!
Asides, today at school, my phone was on complete idle standby with lowest possible brightness and Wifi off (but mobile data on) and by 2:00 (6-2 so 8 hours) I'm down from 90% to 75%.
Is it defective or is what I'm getting normal?
Edit: Forgot to add I have a Tasker that disables mobile data when turning the screen off.
Edit 2: The Tasker profile is for the screen facing down, not being off.
Still, is that not a lot?

What are you complaining about those are great numbers. Losing 1% every 5 minutes means 500 minutes of screen on time, which is 7 hours and 10 minutes. Remember that's just with the screen on. With the screen off and sitting in your pocket you will lost about 1% per hour.
2g/3g/4g...each step you take the worse it is on battery. Restrict to 2g (edge) if you arnt downloading or doing anything. There's lots of toggles. What Juicedefender does is kills the connections untill you turn the screen on and I believe periodically between screen ons to pull any texts and such. The weaker the signal strength (bars) the more battery its using in order to stay connected. Try a few things and you'll be surprised at how stepping in a little to restrict its juice use will make a difference in battery life. Plus, as mentioned, give a few days to build those batt stats up, then it will give a more accurate measure of the current capacity.

So you lost about 2% an hour. Typically you should see 1% per hour. So either you were in a low signal area which caused it to use more power to find a signal, or else you last charged it with a USB charger which prevents it from going into deep sleep (known bug). Or you could have a misbehaving app.
Download CPUSpy from the market an BetterBatteryStats from XDA and see if your phone is deep sleeping and check for wakelocks.
I last charged it with the OEM Samsung charger.
Is that the problem? The reason I started this thread is because I see people reporting (yes I know) that on standby they get great battery life.
Sent from my SAMSUNG-SGH-I717 using xda premium
Every phone discharges differently, especially when new. The overall life is what's important as to whether it's acceptable to you or not. Give it 2-3 days of good ol fashion heavy use. A few good full charge then full discharge are good for getting a good baseline. I remember one of my phones would lose it's top 10% (100 to 90) in a matter of minutes of being unplugged, but then would be fine the rest of the day. This is what I mean by the overall being the important part. But the rogue app part could be something to look into. Aften when we get new phones we go hog wild with new apps with the "lets see what this baby can do" mentality, I say this because I am very very very guilty of it. Sometimes you get an app that malfunctions or is just straight BS. There some that open by itself. Some that you get Ppush notifications about buying ingame currency for and other shady stuff. I try to install only a couple apps a day to keep an eye on weird stuff happening.
Thanks for the replies everyone.
Chief Greek, are you seeing around my results or do you think it is simply a matter of my battery stats not being correct as you said?
Sent from my SAMSUNG-SGH-I717 using xda premium
I have been using my method I stated in my first reply. Here I sit about 9 hours later and my phone is at 92% with no supplimental charging.
Do you know of a way to get a 4G toggle into the dropdown menu for easy access alongside Wifi, Rotation, etc?
Those are some good stats though.
Edit-One app I do have installed is "RAM Manager" and I replaced Samsung settings with settings in app. Could that be detrimental&
Sent from my SAMSUNG-SGH-I717 using xda premium
Havnt played with ram manager, although used something called cachemate before. Seemed to do the trick when phone was acting goofy or very lagged out. I would wait a few days and see if it levels out. Keep screen off when you dont need to use it and if you really really want to do something about it now, install the free juice defender and see how you like it. If you like it and want more controls, upgrade to one of their pad versions.

I loose 1% per 20-30 minutes on standby =/ What settings do you have/how many apps do you have? Do you keep Wifi/Mobile Data on all the time? Reason being, I want to get this figured out before I root/go any further. If it is indeed my own issue, I want to to get it sorted out. Is it worth a factory reset?
Not to get off topic but are the batteries from the international version and the Att version the same? Could they be a different type or manufacturer?

I am not an expert answer on this but yes, I'd like to think so. In some cases it would not be the same (being that ATT has NFC and International does not) but considering the NFC chip is NOT in the battery, it leads me to believe that the they are the same 2600mah batteries.
So, I was just with Samsung chat agent (who probably didn't know a lot about the phone) and she said lost of 25% was normal standby. Am I the only one with this? Techntreck, you get hours on standby?

10% Battery left at this point. I started the day with 100% at 6:20am. It's 7:58pm (19:58) now. Is this bad?
okay well today I decided I wanted an upgrade, Im not eligible until Feb 1st (or a few days after) so I called tech support and was crying about how my upgrade is 2 weeks away and how i really want a new phone. so long story short, they directed me to my local verizon store after changing the date to today; an hour later home with the DNA.
and I am impressed.
I have the galaxy note 10.1 as my main tablet, and the Droid Dna is much snappier than that, and their specs are pretty much the same.
so as much as I "hate" htc, i bough the dna because i thought it looks cool, and im glad I did
and I dont hate HTC, im just one of those frustrated T-bolt users lol, and now my grandpa is rocking the t-bolt and loves it...if only he knew what android 4.0 was......

It only lasts about 7 for me:/
And this is day 2, so I jay take it back and exchange for another dna, as this could be a faulty battery, or sidegrade to a s3
Now heres what my usage is;
Im a college student, so my phone is off charger by 730 am (from the night before) and comes to school until about 3 or so.
In just those 8 hours, with wifi off, gps off, brightness set to auto, and only like 30 mins of screen on time; its at like 30-35
And 3 isnt a good time to die cause I have the rest of the day I need it, so is it me using it wrong or maybe bad battery?
Cause im debati on going to verizon tomorrow to replace it with a s3 or a new dna

why would that possibly prolong the battery life?
my signal at my school is maximum bars , and 4g.
and okay, ill be heading over to verizon in a few minutes to see what they wanna do
because the dna should get at least 12 hours of my "low-average" usage
and okay, ill try to get a new DNA and if I do ill put the brightness somewhere in the middle instead of auto brightness.
thanks all!
Try this app: Deep Sleep Battery Saver. It has worked wonders on my DNA's battery life. It turns off apps and the radios for the WiFi and Mobile Data when the device's screen goes dark. At set intervals, it'll wake up the radios and download email, etc. You can also whitelist apps that you do not want the app to shut off, like an alarm clock app or an SMS app. You will still receive your phone calls. As of this writing, I have 94% battery 5 hours after I disconnected the phone from the charger. I have made a few calls and texts. I haven't used data since I am at work and am in front of a computer the whole day.

I agree with what everyone else said - you probably had a defective unit. I use my DNA much more than you do, with Auto-sync on, Background data on, Mobile Network always on, Brightness at around 40%. In my daily commute, I total around an hour of time spent underground in a subway station with no signal. Given all this, with ~3-4 hours of screen-on time, my phone lasts me from 7:45 in the morning all the way through until ~12 midnight with usually at least 20% battery life left. I don't know if it means anything, but I charged my phone fully before turning it on for the first time (I didn't even let the Verizon store rep turn it on to activate it for me - I told him to not even open the box). If you're interested, this is what I did:
1. Made sure the phone was not turned on at any point before I took it out of the box.
2. Took the phone out of the box without turning it on and plugged it in.
3. Waited for the light to turn green, then unplugged it and let it sit for a few minutes.
4. Re-plugged the phone (the light would be orange again), and waited for it to turn green.
5. Repeated the unplugging and replugging process until the light turned green almost immediately upon plugging in.
6. Turned the phone on and did the activation and all that fun stuff.
7. Used the phone normally, and did not charge it until the battery was fully depleted (turned off by itself because battery was too low).
8. Fully charged the phone until it was full again (without turning it on).
9. Repeated the unplugging and replugging process again until the light turned green almost immediately upon plugging in.
10. Turned it on and started using it normally from that point on.
I'm a bit OCD with my phone battery But hey, it seems to have worked out well for me so I'm happy!
Juicedefender is the best free battery saver I have tried.. Just having it on the balanced pre-set made a difference.. After suffering through the Tbolt, Droid razr, and Gnex, I'm pretty happy with the battery

Well I unfortunately went to the dark side, no not the company with a piece of fruit for a logo...samsung
And I wanted the dna but the lady told me that the battery life is normal for that phone cause of the big screen with 1080p and a quad core processor. I tried to disagree a little, but then she told me she has had the s3 since its launch and she hasnt had an issue yet. So I played with her phone, cause demo units are almost always bogged down. And I liked it.
So as of now, im off the htc bandwagon....but hopefully ill be back in about 8 months when my next line is available for upgrade
