What kind of battery time are you guys getting on the original battery?
I've had my phone for about 14 days now and im not getting more than 12 hours on a charge.. the first week iv'e been using the phone alot.
I have alot of apps installed and im wondering if that could have a impact on the battery.. i have tryed using a task killer and without..
From the battery usage statistics page the screen is definitely the one that uses the most. Voice calls is number 2.
Will all applications show on the battery statistics page or is this something the applications have to implement?

My battery has gotten better since I got it. But I have been doing a few things to help my battery - e.g. I completely drain the battery (until the phone doesn't even turn on anymore) and then fully charge it overnight.
Read about task killers and Android here: http://forum.xda-developers.com/showthread.php?t=849974
All apps will show in the battery usage statistics. If the screen has been using the most power, that means exactly that - you've been using the phone a lot and as such the screen has been taking up a lot of power.
I would recommend though to try to completely drain and then overnight charge, and repeat that cycle as often as you can.. I'm no technician, but I do think how you charge the phone matters
i've read about the task killers and have decided to uninstall them compleetly and let android do what it wants.
Regarding the charging, i have ran the battery flat out almost every day..
Im going to try a few different charging methods and see if there is some difference..
however i suspect that if the indicator is saying 100% charge, thats exatcly what it is whatever the charging method. (i hope)
It does get better. When I first got the phone I was getting about 14 hours. Now I'm getting about 30 hours or so.
JuiceDefender and setCPU help preserve battery life, too.
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.
i always thought completly draining a Lithium-ion battery is a bad idea?
Yes, it is.
Older batteries such as Ni-MH should be completely worked out from full to dead in order to keep them going in the long run. Li-ion doesn't need to be worked out, in fact the more it is worked out the faster it will run through it's lifespan and stop holding a charge.
Now that batteries, phones, and chargers are all smart, it's supposedly good to keep them plugged in as often as you can instead of letting them run dry.

The post (#7) above is correct on this. You should not let the battery dip below 30%, since discharging it too low may prevent it from being able to take a charge. It happens to most of us on accident every once in a while. But you should avoid it if possible.
It is good to run through a couple charge/discharge cycles to calibrate the battery meter. Many people still think this is to "condition" the battery, but battery conditioning is only the case with the older NiCad type of rechargeable batteries. Charging/discharging the battery just helps calibrate the battery meter on the phone. For new phones or a new ROM flash, I usually charge the battery to 100%, then let it drain to 30%, and repeat a couple times.

It's also a bad idea to charge a cold Li battery, but I believe that affects lifespan more than charge. For those of us in colder climes, remember to wait for the battery to warm up to room temp before plugging in.
On my DZ I usually get 15~20h of battery life and it's O/C @ 1.4Ghz
3G & wifi : always on
facebook, gmail, emails, news, weather updates each hour
about 1h per day of audio streaming (deezer, Synology DS audio)
1~2h of internet and games per day (baseball superstars, angry birds, psx4droid...)
less than 30min of calls per day and about 20-30 sms...

It depends what you mean by "completely". If you drain the voltage of a LiIon battery too low, you will damage it. But the circuitry of the phone is normally designed that there's a cut-off before you get to this, i.e. "completely" discharging it by running it till the phone turns off will be before this dangerous level, so should be safe.
It's unnecessary though, your phone can tolerate a *lot* more partial discharges/charges than full discharges/charges. If you drain it ten times from 100% to 90% and charge again, then that's roughly equivalent to one whole discharge/charge from 100% to 0% and back again.
As redpoint73 said, the main issues it "training" Android to get the battery calibration right, not conditioning the battery (which only applies to NiMH, NiCad, etc).
Li-Ion batteries are protected from deep discharges in two ways:
1. The Phone, it will stop you from discharging too low.
2. The battery itself. Each Li-Ion battery contains circuitry that stops it from discharging too low.
Basically both have to fail to have you end up with a dead battery -> rarely happens.
Li-Ions take the heaviest duty when charging the top 90-100% charge, charging just that bit stresses the battery more than from 0-80% (ofc 0 not really being 0 ) Note: This only has an effect on battery LIFE, not battery capacity! -> if you keep charging your battery from 90-100% (for example by keeping it plugged in after driving to work, then recharge after driving home, basically always going from 100-90-100 you're really doing your battery a disservice life-cycle wise)
If Li-Ions are not in use for a while they should be stored at around 60-70% charge.
Now as for batteries in Android devices, I'd estimate that most causes of extreme battery drain are due to rampant programs/too many internet accesses.
Everytime you log onto the internet, or change speeds (3G -> Edge-> whatever) you take a lot more power than usual. Try to ensure that all your programs that regularly access the net, do so together (HTC Sense interface tries to do this)
Rampant Programs: Especially services that need to poll the clock a lot, or keep updating their info, keep their FPS high (games) It is for this reason I try to avoid installing a lot of programs at once, and keep it one at a time (especially for system programs) to see if there's a inordinate change in battery life.
Oh and do turn off unneeded things like bluetooth, wifi, and GPS if you don't need them... but thats a given.
Gee typed more than I was planning, just get tired of seeing these threads all over

Sorry but I disagree with that. Have you got any evidence to back that up ? Continually charging the battery from 90% to 100% should be fine and shouldn't shorten its life at all. Chargers will sometimes reduce their charge when the battery is nearly full, and a slower/lesser charge will actually increase its life (I have no idea whether the DZ's charger does this or not).

Coming from the Touch Pro 2 forum, there are somewhat occasional posts by users that discharged their batteries too low, and get stuck in a boot loop. Leaving the battery on the wall charger (USB is not enough) for a long period of time seems to solve the issue in some instances, while others are forced to replace the battery.
As you said, instances of this are relatively rare. I've drained my battery until the phone shuts down plenty of times on accident, with no ill results. But best to play it safe and not do it intentionally.
When you mention the phone prevents the battery from discharging too low, is that the hardware, or the OS? I guess either way, maybe the Desire Z or the Android OS are better at this then Windows Mobile and the Touch Pro 2. But I still wouldn't discharge the battery too low intentionally.
I'm pretty sure on the Touch Pro 2 it was software based (hence actually allowing you to boot before saying "not enough charge" )
I doubt that ANY charger that comes with a phone is anything but a normal "charge till full" charger...

Are you using it pretty heavily? I just got the phone Tuesday, and still playing with it a lot, so I can't comment on battery life yet. But what is your screen brightness set to? If you look at the battery use graph, you will see that the display uses the most power, and with any smartphone, the biggest culprit of short battery life. Turn the brightness as low as you can tolerate for your "average" viewing conditions. Also, be sure you've calibrated the battery meter as I've described in Post #8 above.
A word of caution as far as the Mugen extended battaries: one of the users here did a bunch of battary tests on OEM and different aftermarket brands, on various phones. The Mugen 1800 mAh batteries did not rate any better than the OEM 1400 mAh. Mugen tried to explain away the test results. But judge for yourself.
http://forum.xda-developers.com/showthread.php?t=583927
My screen brightness is just 25 or 45%. And i really don't make it to the end of the day.
I now have setcpu, so that when my screen is off my cpu is running on 300mhz. Think i can make it now through the day.
I use my phone a lot, thats true. But only to view the market or twitter things..
Ow and i don't use live wallpapers...
I think there is a lot to be said for keeping things turned off if you do not use/need them too much.
I leave my phone charging overnight (between 11pm and 6:30am). So when I leave the house in the morning it is fully charged.
I keep Wifi and 3G turned off unless I need to use it and I keep brightness to a minimum - again, only increasing it if I need it.
Normal usage for me would be about 1 hours music listening during my commute to work, a couple of texts a day and about 10mins worth of calls a day.
On top of that about 4 hours worth of data use (both Wifi and 3G) and I usually find I still have over 50% battery life left when I plug it back in around 11pm before going to bed (according to the Mini Info widget).
Granted this is fairly light use compared to some people, but I think if you take the time to control your app usage you should see better performance results!
I've gotten my seidio extended battery and have never really tested it to its limits. I would like to have it functioning optimally. I have the app "Battery Monitor" installed which can calculate the percentage left via the voltage as opposed to the stock battery indicator. I am currently showing 57% via the voltage monitor and 35% via the stock monitor. I have found that my battery can drop to ~1% (according to the stock indicator) however the voltage indicator would be at something like ~30%...my phone would turn itself off at that point in time and I would not be able to take advantage of the reported battery....I have followed directions from: droidxforums.com/forum/droid-x-general-discussion/18216-disable-low-battery-warning.html...I bootstrapped and reset the battery...but nothing. I was wondering if anyone has had any experience in this or could help me out.
Thank you.
I think if you go into the screen where you clear the Dalvik Cache in the recovery menu there's a battery settings function. If i've read some of these posts correctly, that calibrates the phone to the battery. basically re-adjusts the 0-100 range on the phone.
You need to do this when the battery is fully charged.
Draining your battery all the way down will destroy your batteries capability of holding a charge in the future.
Your phone is suppose to only charge to ~90% and cut off at ~10%.
Ultimately this means you are only using 80% of your battery, but it's how Li-Ion batteries works.
If you truly drain it all the way down you ruin the battery.
There are some things you can do to recalibrate the software that determines the charge level of the battery though, like the above post suggests.
I don't know if you're running a custom ROM, but if you are or aren't you should definitely check into changing your phones Kernal to Chad's or IncrediKernals. They drastically improve battery life.
For me, it gave massive improvements for 'screen off' (1% depletion every 1 hour) and significant improvements when using the phone.
Of course I'm using the HTC extended battery, but that was much better than the 3-5% per hour I got before.
hello,
please tell me what's wrong with my xda iis. when the power below 75% and i activated wifi/camera/any apps, oftenly it turn off by itself. also, it often signal loss or cannot make/receive calls. thanxs
I completely drained my battery from 100% until the phone shat off and then charged it to 100% again before calibrating the battery using the "battery monitor widget" app. After that, my battery seems to be draining even quickier than before. With the screen being at the top of the battery usage graph although my usage is the same as before.
Anyone else having that issue? I am rooted and running zedomax's kernel v2

Sounds about right. Every time I've "calibrated" a battery this happens. Run it dead the first charge. Then give it a few days-to-a-week before making another judgement. So long as nothing happens to your battery stats and nothing extraordinary happens WRT charging/discharge you will then have (what I consider to be) a well calibrated battery. If you don't like the results, too bad. I consider them more accurate than the very rosy outlook you had before calibration.
Myself? I haven't been burned by the battery lying to me yet so I haven't bothered to calibrate. I only do that when I feel the meter is way off base...which is hard to tell since usage can vary so much from day to day. Only when it is glaringly obvious that something is awry do I do this...mostly 'cuz it takes so long to get things back to normal.
In summary, yeah...sounds about right. Don't panic and just use it normally if you want an accurate meter, whether you like the truth or not I think you'd prefer the truth.

Your battery behavior sounds to be normal.
You should be getting about 1% battery drain per hour when screens is off.
You should be getting about 1% per 2-3 minutes of screen on time, depending on usage.
Evo4g and Evo3d were getting about 1% per 2 minutes of usage.
This phone isn't that much different.
When it dies after calibration, you should charge it to 100% without break.
Following calibration, batteries still take a little time to settle. Give it a week or two and you'll see its true discharging rates.
Also, I've never heard of that app. Use the Battery Calibration from Ne'ma.

Battery Calibration by Ne'ma works well for me. The above posts sound right give the a few cycles to settle in.

I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.
Also, kill the Social Hub as well, that drains the battery significantly.
You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.
Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?
I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.
I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.
Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!
From my personal experience and some googling i found out that a combination of juice defender and GSam battery monitor will drain your battery dramatically after some days/weeks (I have experienced it)
I was getting 5 hours+ on heavy usage but today these two apps sucked my battery off and my battery went from 70 to 40 in an hour or two.
After some internet surfing i found out this.

I am also getting high usage from the kernel on the stock rom. Sometimes, the battery goes down even faster than normal, but a reboot seems to bring it back to the usual consumption level.
I have also noticed my phone is awake quite a lot while on wifi, but I'm not sure if disabling it would improve anything.
