i spoke to htc about the abysmal battery life, they say that there could be extended batteries in the near future, with a new back cover (with the back sticking out)
i dont mind charging it every day but
everytime i do something basic, for couple of minutes, it goes down by 1 percent, everything is turned off, gsm 2g mode, etc.
anyway the guy at htc said its due to the massive screen, this is what drains majority of the juice,
For what this device has and what it can do the battery life is pretty good, if you just use it for a few random pics, bit of browsing, bit of music and a few calls you should get a days use, if you sit there for ages messing with it its gonna drain.
Im pleased with it myself, apart from the bugs, but waiting......
It's killing you literally? Step away man!
I find the battery life on-par with other smart phones I've owned. I use a desktop cradle (well should soon be using a desktop cradle) and an active holder in the car, so I find the battery keeps up OK with a typical day's use for me. The biggest battery killer is when the screen is on full brightness so I find essential to have the phone on power when I'm using the satnav.
I had really high hopes for this thread when I read the title. Needless to say, I'm pretty disappointed.
Where's the death I was promised?
Die and prove it.

To be fair most smartphones drain their batteries pretty damned quickly. Disconnect your data connection when you're not using it and bluetooth too. OK so you won't get weather updates but you'll save battery life. Just charge it nightly and buy a car charger if you really drain that sucker!
Wow, I think battery life is good considering the screen, better than I expected.
Currently, with screen set to 70% brightness, push email on 0800-1800 with hourly retrieval outside those hours, hourly weather/Twitter update, automatic Quick-GPS almanac data update, I last all day (~0700 to 2300), and still with about 20-30% headroom with the following use:
Push email as per above settings
50 minutes GPS tracking
50 minutes bluetooth on (heart rate monitor)
1-2 hours listening to music
Around 1-2 hours high-drain use (screen on, using cellular data/WiFi/GPS - for example browsing/app use/gaming/watching video)
30-40 SMS
15 minutes calls
One simple little trick that I learnt some time ago to preserve battery life is ..........turn down the brightness of the screen display. The brighter it is the more juice gets used.
Get the screen to turn itself off after, say, 30 secs of use. That also helps.
The rest, such as killing off data connections when not in use, etc, you already know.
It never ceases to surprise me at the number of negative comments re battery life. The impression I am left with is that if the battery does not last at least 2 months between charges, even though it is being hammered to within an inch of it's life, then that makes the battery performance rubbish. Anyone ever heard of a battery charger?
It's a really easy to use piece of kit that comes with your device that can be plugged in at night when you are asleep, leaving your device fresh for the morning.
Amazing.

What the heck do you expect from such a phone? The energy management is kinda good and it's the display that kills battery life. You have to get use to it. At least my Touch HD seems to last much longer, but I would never change back.
If you watch a video your battery capacity drops quickly. I estimated 4,3-4,5h of HW-acc WVGA video and 3,5h with a non-HW-acc VGA video. Not that much but it really looks fantastic.
My Solution for this problem is: second battery, extended battery and/or load the battery whereever u can. My normal usage drains 30% of the battery a day, so I get 3 days of normal usage (I'm not an excessive handy user). The standby duration is with 300h not that good, but yeah that means still 12,5 days of standby if I calculated correctly.
The point is, that the phone is that good that I'm attracted to play with it and then the battery life tends to last just a day or less.
I bought a second battery (~22€) just for longer rides. I think it's ok.

EEK!, don't come on this forum and complain about the HD2! not allowed. this is now the official HD2 Appreciation society, don't ya know.
I recommend instead you buy some lube oil, massage it into the device, light some candles, play a bit of Barry White, and all will be well.
Then come on this site and reassure all the sensitive souls here that it is indeed the Holy Grail of mobiles and admit you are a Troll for finding a fault with it, and daring to ask about why it does not preform as it says on the tin.
And final advice...In the words of legendary Basil Fawlty... Don't mention the War !..or in this case, the Keyboard!!, I mentioned it once...and thought I got away with it..but no.

Exactly !!
1000 Mhz this bugger does.
And really its more then just a phone. with the battery cunsumption like wise.
But they told me one thing,,. something that Noone does
When you get the HD2. Its battery got 20% juice init.
Thats not for fun of the company (prolly sanyo) was laizy and dint bother to fill em 100%.
You have to charge the battery 6 to 12 hours and to peeking at your new jewel.
And i know Noone ever does that. But it ensures batterylife and eficiency
Here is the article >>
Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity.
Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours.
Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized.
#DO NOT fully discharge a lithium-ion battery!
Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them.
Instead, charge them when the battery meter shows one bar left.
Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them.[1]
2Keep the battery cool.
Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature.
In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.
3Charge your battery correctly, in accordance with its type. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is.
Nickel-based batteries (either NiCd or NiMH) DO NOT generally suffer from a misunderstood phenomenon known as the "memory effect." As described in Wikipedia and many expert sources,[2] the term "memory effect" has been widely mythologized to describe any and all deterioration of NiCd (and other battery chemistries), in many cases misleading consumers into further shortening the lives of the batteries through over-discharging to "recondition" them.[3]
[This section formerly read: If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged (sometimes several times). The appropriate length of time between reconditionings varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available. [4] ]
Lithium ion batteries can be preserved by careful charging and avoiding storing them at full charge.[5] They do not require "reconditioning."
Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

It's a shame most powerful mobiles heat up like nobody's business whilst on full chat these days.....there's no chance of keeping the batteries cool! Still, it's an expendable item and at least you can buy a replacement.....none of this iPhone 'sealed' tin rubbish.
while i find the battery life reasonable with the features this phone has (read screen size, processor speed), it will be nice to get the CPU throttling app another thread is discussing. don't need that 1000MHz running everytime i pick the phone.
On the same notes, how can i check if automatic screen brightness is kicking in?

Stick the phone under a bright light such as a desk lamp and cover the light sensor with a piece of paper.

are you the first wm phone user? Do you have good experience with phones that has so much specs? Do you use wifi and browse with phone very heavily? If you do, it is really normal that the battery will drain. My Touch HD does the same, it can last a day or 2 or drain like water not more than half a day, it depends on your usage. Try to get a second battery, or even the third one like I do, what is a big deal? It is completely normal.
I don't have a lot complaints on this phone as it meets most of my requirements.about the battery, I seriously don't think it is that bad. for example if you have a car with 1500 horse power and expect it to have or rather 30-40 mpg, don't think it is possible. try to use your local gas station (in this case your friendly charger) more often.move on with your life please.

That might be a little difficult because this battery problem is killing him, LITERALLY
So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,
Rocky
Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.
I have been letting a couple of days go by to see how the battery is and I have got to say that I am highly not impressed. I love the phone and even like Blur but the battery is really a let down. I know that the first day or so that I use the phone heavily because of course.. ITS NEW. But today I have been real busy at work and have maybe text a few people, made 2 calls, and looked up a number using google maps and my battery is now down to 60%. In battery manager, it says 5h 2m 25s since unplugged which would be me taking the phone off the charger this morning and heading to work. Other stats are:
Display 35% 29m 52s
Phone Idle 26% 4h 32m 47s
Voice Calls 24% 6m 45s
Cell Standby 11% 5h 4m 5s
Wi-Fi 6% 1h 51m 56s
From looking at these battery stats and usage, does it even seem correct to be at 60% battery? This is at the least very minimal usage for a phone.
Yet another battery thread... One thing before people start complaining: don't estimate battery life based on battery gauge! Complain once the battery is dead and you HAVE to charge. That's the real mileage you'll get from your battery (and give it a few days to calibrate). The gauge is not a good indicator.
I am a new Atrix user too and so far the battery life is 12hrs or less. Maybe that is not impressive. Coming from the N1, its alright in my book.
I do want to say to everyone complaining about the battery life:
It can take a week or more for the battery to settle into the routine and perform to its maximum ability. Lets start the conversation again later next week on where our battery is at.
Yesterday I got 13 hrs between unplugging the phone, and getting the 15% warning. Not all that bad. Not great, but definitely could be worse.
mine has yet to drop below 30% and im pretty much browsing the web and texting all day. I dont care what kind of phone you have but making voice calls and playing games/watching videos kills battery with a quickness no matter how big a battery you have. . The atrix in my personal usage is just as good as my ip4 was.
the atrix was very good on battery life compare to other android phones i've had
Have the Atrix and Epic 4G and the Atrix lasts easily twice as long as the Epic.
I have to keep he Epic pluged in for my hour comute with pandora, just to make sure I have enough battery to make it for the trip home. Normal usage during the day with brightness all the way down, wifi off, BT off, sync On.
Had the Atrix today (day one after full night charge, unpluged at 6:30a), kept BT On, WiFi On, Brightness 100%, Sync On, Exchange Sync On, Auto off/standby set to 15 minutes, Pandora on via BT for my hour trip (unpluged), forest Live Background, Weather Widget etc.,downloaded everyting I could think of/find, constant e-mail, and constant "whatsApp" till noon (lunch), wache YouTube Videos for my whole hour lunch (still full bright mind you). Created 10 minute Install Video with 720p for work, then uploaded via WiFi, not USB. More Texing, Calls and Downloads. .... FINALLY haed to plug it in at 2:30p, with 5% battery left, I think I could have made it till 3 for sure.
That's a full 8 hours of NonStop Use of everything. I expect to get Morning-Night life from normal usage.
Final word. Test it first. I did and it's Great, not just good. The receiving end of all my texts and e-mail blasting and video look ups has an iPhone. He had to charge his at 2:30 too, but has his iPhone set to max battery save (brightness 15%, wifi off, sync off, etc.) But was using as intensly as I was
... okay I'm done ...

Well I must have a bad battery or something then because I am not doing nearly half the stuff that you are doing and am now at 30%. Is there any special charging methods or anything that I should try to squeeze out a few more hours on this puppy?

may be you have several internet connected background service running behind the scene?
My attitude towards the battery is a mixed bag.
1) PRO: It blows away the battery for the Eris (which I'm coming from)
2) CON: As these phones come to be computers with phone capability, it's really time for manufacturers to try their hardest for better batteries. I'd eagerly accept a phone twice as thick as this one if it meant double the battery life.
I find mine is only good for 10 hours (much less with heavy usage, but low calling time). I expected more.

I really call bull on this.
Coming from the world of Airsoft, I'm no stranger to battery performance.
Most of these performance myths are hold overs from the Ni-Cad days and don't apply to modern batteries.
Call Bull all you want. But it was true to the N1 and so far its been true to my battery. It does not last the first few days and gets better after a few charge cycles.
Frankly, everyone believes whatever they want on batteries. I for one take it as a user by user experience. I watch my battery life a lot, but I also like to have Google Reader and Google Listen syncing.
I'm at 30% right now and 12 hours unplugged. What I wouldcall moderate use. Its not as good as my captivate on custom rom / kernel but its far from bad enough.for me to complain about

Andriod sucks the battery, bigger battery on Atrix didn't help much. Google need to optimize the OS for better battery management. I am disappointed coming from Samsung Focus & iPhone 4, both have superior battery life. BTW, I am on Day#4, conditioning the battery didn't help any so far..
Within Range
Looking at all the comments - I would say the Atrix is within range -- I knew when I saw the 1950 mAh (or whatever the exact spec) that the tegra processor must really be a power hog -- the new processor, along with the huge screen is going to draw a lot of power. Comparing to other phones with single core processors and screens even 20% smaller is not reasonable.
Definitely a good point... going to be interesting to see how well other dual core are going to hold up. That will be a better comparison.
Is that battery really a 1930mAH? The size looks like any 1500mAH battery isn't it?
I managed to get close to 16 hours of 'normal' use, meaning I wasn't trying to drain it, nor was I trying to conserve battery. I took the phone off the charger at 3pm and made it all the way to 2pm the following day with about 20% left. That's 23 hours, but I subtracted out the time the phone was on while I was asleep, 8 hours (nighttime mode).
Hmm hearing all these replies i believe i have a defective battery. I unplugged mine today at 5:15AM and now it's 2:18PM and it's just gave me the 15% beep. I've sent about 25 texts and played some words with friends. I've got watchdog installed and no apps seem to be out of control. I'm wondering if a factory reset would fix the issue or if i should return it.

try going to your dialer and entering *#*#INFO#*#*
Look under the battery usage and check the different items. Is anything using a significant amount? it could be a rogue app.
I will say MotoBlur has a lot running in the background. About twice as much as vanilla android.
I have turned most of this off and I do know that is helping my battery life.
Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!
Why is this in General as well as Q&A?
Put this in Q&A, didn't get any answers. Went to General, saw that more people posted there, even for Q&A's. Have an actual problem that research didn't help much with, so made a thread. If necessary, I would be glad to remove the thread on Q&A.
By the way, thanks for the answer .
Would you be able to post your software specs? Radio version, rom version, android version? My Bell DZ only loses about 3% per night if I don't plug it in to charge. I, like you, have wifi, gps and hspa enabled with no huge I'll effect.
The stock battery is usually alittle weak. Being a 1350mA, it doesn't have the capacity either, but that is why it is user replaceable. I picked up the mugen 1800mA battery that gives the phone the stamina to last a full day of full use or 2-3 days of light use. I forget how much I spent on it but it was definitely an upgrade.
As for the signal issues, we would need to know what you are running. The latest .30 radio is recommended for AT&T if I remember correctly. Also, the type of rom (stock or custom) might give us abit more insight.

I lost about 10% overnight today I believe, possibly 15 (don't remember exactly what I left off at).
Not sure on all the stats because I don't know how to check them but
Android Version 2.3.4
Cyanogenmod 7.1.0-RC-Vision (seller did it for me)
What is the radio version? I think that is baseband not kernel? If so its 12.52.60.25U_26.08.04.30_M3
-------------------------------------------------------------------
If anyone knows about the sporadic data, that'd be helpful. It does seem that if I go into airplane mode a few times it fixes itself, but I doubt everyone does that to ensure fast HSPA speeds

I've never used CyanogenMod Custom ROM's before, so I can't speak from that experience. I can, however, tell you that while running RMK (and team's) Custom ROM's (Virtuous, G-Lite, Unity) and now MIUI, battery life has been excellent, even with the stock battery. The current build of MIUI lasted for about 15hrs on a day of full use, RMK's ROMs would last about 12-15hrs of moderate to full use on the stock battery. Alot of the custom roms have different power management settings and tweaks, if you're comfortable with flashing, I would recommend another ROM and see if that helps with either of your problems.
If you like the Vanilla/AOSP look of android, try RMK's G-Lite ROM. It is very lightweight, fast and stable. I remember having one issue with it, but it was a very small issue and didn't stop me from using it for a few months.
I am currently on MIUI English 1.7.1 and with moderate use I am sitting at 50% charge spent over 2 days. Moderate for me is about 300 texts with about 10 phone calls and a total of about 4hrs of web browsing.
I can link you to those roms if you need, but they're all located in the Dev section. Your radio seems like it's on the right version, so perhaps it's not the issue. Try running another rom for a week and see if that helps to any degree.
I re-calibrated the battery, let it die, charged it up, let it die, charged it up. I followed the instructions to the letter and all that.
It was at 100% when I went to sleep. Woke up 8 hours later, 74%.
Settings > Battery shows nothing high 40% for cell standby and phone idle. Everything else (Facebook, etc.) REALLY low.
Then I went to Spare Parts > Battery Usage, Partial wake usage, everything incredibly low as well..
I will try Watchdog, but could it just be a bad battery? Or maybe should I try a different ROM?
Thanks!

NO! This is poor recommendation, and people need to stop perpetuating it. People keep recommending this, but its NOT a good idea to let the battery drain until it dies, just to calibrate the battery meter. While the protection circuit on the battery will USUALLY prevent over discharge, it is not 100% failsafe. There is a slight possibility that over-discharge of the battery will happen, and then the battery is no good, and will need to be replaced. Unless you have a special battery meter with a "boost" function (which most people do not have access to). See the following table on Battery University, where it says for Li ion batteries: Discharge: Prevent full cycles
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Best practice is to charge to 100%, drain to about 20%, repeat a couple times. No need to go below 20%. The battery meter is not very accurate to begin with, so there is no value added going to 0% versus 20%, but you risk killing the battery.
Plus people keep abusing the terminology. You are just calibrating the battery meter, not "calibrating the battery". When people say this, I think its just a holdover from the old days of NiCad batteries, where you had to condition/discharge the batteries periodically to prevent memory effects (Li ion batteries do not suffer from memory effects, and require no period cycling).
Can't really speak to the Atrix or the iPhone. But the battery drain on the DZ described by the OP is right in line with what I've seen. I also have an unlocked Bell DZ on AT&T, and battery drain of 2-4% (on various ROMs and couple different radios) when the phone is completely idle, screen off is totally normal. Best I've seen on my DZ is with the Virtuous Unity ROM and the .30 Gingerbread radio, where I've seen somewhere around 1-2% drain per hour when idle.
One possibility, is that the different phones are not reporting % battery the same way. As I've mentioned above, the battery voltage meters on phones is not very accurate, maybe in the range of 5-10% accuracy (although, even with this, the drain on the DZ versus the ATrix and iPhone still sounds inconsistent). But what is more important is how many hours of usage you get before needing to charge.
Thanks for the info.. Ill try charging that way.
And I honestly think the battery is just reading it wrong. It honestly feels like it dies faster idle than not, go figure. Yesterday, at like 10% battery, I wanted to kill it off, and played a game for like 10 minutes straight, still 10...
Then I tried leaving the flashlight on for 10 minutes on and it maybe lost 1
How is that battery I recommended from dealextreme though?

It's interesting to see all the troubles that people are getting on the DZ...
I've had my DZ for about 6months and never seen any of the reported problems.
My 1350mha will last me on a frequent usage near 24hrs and if I'm using it lightly like when i'm busy at work... almost 2days worth.
Mind you I'm running Cyanogen MOD7. No GPS. Wifi is on and I use JuiceDefender.
Cheers mates.
Last night, I charged my phone to a complete charge before going to bed to see what kind of drain I would see overnight. After 9.5 hours, my battery had only lost 2% sitting idle. That is with 3G on, but no Wifi or Bluetooth enabled.
The phone idle accounted for 47%, cell standby 48% and Android system 4%
While it seems remarkable, I'm still not convinced that its not my phone incorrectly reporting the battery level. On a typical day when I pull my phone off the charger, the first 10% is very slow to drain. Today, I have sent a few text messages and played maybe 3 minutes of word feud. That has drained 6% of my battery.
We will see where I'm at later in the day. I suspect that the actual level is lower than the 94% it is reporting. Typically, I get between 12-16 hours of usage, depending on how much I play with my phone.
Well I am at nearly 23 hours on this charge. Have used the phone rather lightly during the day. It sat idle for about 9 of those hours while I slept last night.
Conclusion: Idle drain is very minimal on my device and looks as though the percentage was being reported rather accurately. I'd say if you're having a lot of drain while sitting idle, do some digging and find what it is.

But I used my iphone at work to watch videos, ect while there is downtime. I usually watch while it's also on the charger
For the Note series, does anyone know if that "kills" my battery for long term?
I know you can replace battery, but just wondering for future use.
Thanks.
Issue with battery drain due to android system is real
All three people I know that just got the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 where they were experiencing the same issue (lose around 12% battery an hour with android system taking a huge chunk of battery). The person from that post was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!
mine took about 2 full days for everything to finish syncing, downloading, indexing, etc. I had books, news articles, pinned music from google play, etc.
Once that happened, everything is now "normalized" and I'm getting better battery life than I was with the note 3.

Short answer: Maybe, it depends on how you are doing it. Using it while it is charging is not necessarily bad but watching videos and keeping it plugged in while the cell voltage is pegged at 100% will likely deteriorate your battery faster.
Long answer + tips:
Lithium ion batteries are great - they are light, can be made very thin and have excellent energy density but they are also very finiky.
Things to avoid doing with a lithium ion battery
-Charging to 100%, leaving it plugged in overnight is a poor practice(high cell voltages reduce the service life*, stopping the charge at 90%[4.10v] can double the service life, stopping the charge at 80%[4.00v] can quadruple the service life.*)
- Discharging the battery to below ~20% (Li-Ion batteries are somewhat sensitive to deep discharges)
-Charging/exposing Li-Ion to elevated temps or below freezing.
*service life is defined by when a battery can only retain 70% of its rated capacity. Most consumer batteries used in mobile devices have a service life of 500 charge discharge cycles.
It is not uncommon for batteries to lose 30% capacity in 1.5 years or less. Changing your charging and handling habits can double or quadruple a batteries life span.

LOL your picture took up have my damn screen on my 1080p laptop with 15.7 in screen. It was crystal clear too.
On my 2nd charge, auto brightness. Pretty freakin' amazing battery life....
15.5 hours off the charger with 8+ screen on time!
I got awful battery life on the first charge cycle. It drained 50% overnight. 2nd charge has lasted amazingly long and I still have 64% after 12hrs of average use.
First charge. Battery life has been phenomenal. Brightness on auto.
Did u use any power saving features to achieve that time?
Did u use any power saving features to achieve that time?
Definitely improve battery with recent update and I'm a power user
After the latest update
I dont know why but my phone goes from 100-90 in less than a hr with minimal use while the screen is set at auto, also in the leaving it unplugged in the night the battery also drains like 5 points.
I've been at full brightness and using the hell out of it non stop so far, and I'm at 35% with screen on time at 3hrs 40 min.
