So I am one of the people that envies those of you that claim 20+ hours of battery life on your phone. It doesn't matter what ROM or Kernel I use and if I have SetCPU at max 3xxMhz, my battery lasts until 6pm ish (off the charger around 8am) and I have moderate usage. I can use Juice Defender and any other power saving product with no result. My product number ends in F. I have a replacement from HTC on the way and I will report back with the battery life and product number when I get it but it seems as most people with failing battery life have the F at the end. I posted a poll and I'm hoping to get some good turnaround. I'm not too concerned with what ROM/Kernel everyone is using, just more on the product number unless you have seen drastic differences moving ROMs/Kernels.
EDIT: A few points of clarity:
* Sorry for the confusion... I was not referring to the physical battery. I am looking to see people's battery life in relation to their phone's P/N
* Lets set some parameters here:
Bad ~<13 hours and your phone is pretty low
Mediocre Between ~13 and 20 hours
Great ~>20 hours
Just reading the threads, this seems to be the ranges we are going through together. If any of your votes don't meet this, maybe you can change it. I have my new phone on the way and will not root it or change anything... I'll test the battery life.
where's the B option?
and by the way, how many different ending letters are there? do you know?

I didn't throw the B option in there specifically because I didn't know how many ending letters there were. You would chose the option "product number does *not* end in F..."

amazingly i didnt read that correctly.. maybe people here should post what their letter is.
mine is so obviously B
Interesting thread, especially for those of us with poor battery life. On my battery there is a "part number" and on the phone there is a "p/n" number, my p/n number ends with F and I'm guessing that's the number we are talking about?
Also, my vote indicated that I have bad battery life but I don't really know what constitutes "moderate" usage and also, "bad" battery life to me may actually be precisely the type of performance I should expect.... for example, with moderate use my battery is at about 40% - 50% when I get home from school, so that's moderate usage between 9am to 3am and 3 of those ours I'm in class, and I only use it for a few minutes before each of my 2 or 3 classes so I'm really looking at about 20-25 solid minutes of usage, is that considered "moderate"? And if so is 40-50% remaining battery considered "bad"? Thanks

actually, letter
Also can the ones who have good battery life with over a day or more please post your ending numbers.
I actually have two batteries that end in M and I get great battery life. I rarely have to swap batteries, and when I do it is because I took my phone off the charger at 8AM and streamed 5+ hours worth of music via Subsonic, while using my phone for at least four hours of browsing, etc. Even then, I usually swap before the one dies completely. Generally on my way home from work, so when I get home I can play some games without worrying about my battery dying on me.

Hmm is that the phone or the battery that ends in M? Because the P/N we are talking about is the one on the phone.
I have an F and have regularly gone 36 hours before charging.
I think its an interesting poll and although contains subjective opinions may well show a valid finding. However the number of people responding needs to get up to >60 or so to draw any conclusion.

My bad... I assumed that since you were discussing battery life, that the battery was the object you were comparing. So, my batteries have a part number ending in M. Phone ends in F, aren't all Nexus Ones going to have the same part number? I didn't think there were different hardware revisions.
You may want to restate your question as "What is your battery life/product #?" clearly reads exactly that.
Dont think the battery ending in F argument holds any water.
My battery P/N ends in M and I get about 5 hours of life before needing a recharge (normal use). This is not necessarily bad as its a super-phone.
With less use and a few calls the battery will last about 12 hours.
The solution is to be able to charge everywhere Cable in your laptop bag, cable on both home and work desks, charger in your car....
Get the Sedio 3200 if you want close to 2x the battery life and have the cash for it.
My phone's P/N doesn't end in a letter. And I have bad battery life. Around 10 hours of medium usage.
I leve Wifi, GPS, Sync turned ON and display brightness at 50%.

Thats just it. ALL our batteries ends in M. Its the P/N on the phone we are comparing. A good amount of persons are reporting over 20hours or 1.5days of battery life with 3G, gps, gaming and such. Which seems to come within the realm of what Google advertise the battery should be. But some of us can barely make to 12hours with that usage. I recently discovered the phones ending with F seems to be related to bad battery life. Strange I know, hence the purpose of this thread. To test that theory.

How did you miss the big bold F in the statement "I have an F"?

Oh... I just wake, my eyes still drifting..
I meant to say.." With what kind of usage?"
My P/N ends in F and i can go a full day with no battery problems at all. Most of the time i am around 40% or so after about 16 hours. Also i do watch videos on my phone since i am in the Army and do some traveling. I can get by with about 4 2 hour videos before the phone has to be charged. I voted great with F.
I'm not certain there is a "bad battery life" so to speak, rather than the part number i'd be more curious as to what is eating up your battery life. check under settings>applications>running services and see whats going on under the hood
with a full charge i have 4187mV charge, when it wants to shut off its around 3000mV or so. this mV reading is from the "battery left" widget. I highly recommend this widget as it gives you a pretty good idea as to what is using the battery up.
i usually unplug it at around 730am and lasts until about 10 or 11 pm, depending on what im doing that day. to give you an idea of my usage, i check a few rss feeds and check email and play some mp3s from the sdcard on the way to work, then sometimes play in the market a few minutes and do some casual web browsing while at work to break the monotony, check personal email some times , listen to some sd card mp3s and check some tasks in astrid. I have the email sync about 15min, background data and contacts sync on auto, work email on sync about 15 minutes, twitter sync every 4 hours, newsrob sync every two hours, gps on wireless on, brightness auto adjust or 75-100%.
Here are some things I notice that obliterate my battery
streaming music with last.fm - this chews through the battery a bit, I would say it will last about 6 or 7 hours constant streaming over 3g/wireless.
navigation app - using the gps with maps eats the battery up, its about dead after a 1 1/2 to 2 hour trip with no charge, couple that with streaming music and you basically have to have it plugged in if you plan on using it at your destination
no signal - while im at work ive got some pretty poor reception, I've started putting the thing into airplane mode then manually turning the wireless back on, this gives you some connectivity with google voice voicemail and google voice sms while not actually having the 3g radio constantly working to find a signal, the 3g radio really takes a lot of the battery imo. I used the tmo band N1 and put a check in the force 2g connection checkbox(since i was on att) and the thing would last all day plus most of the night, when i got the att band N1 i did notice quite a bit of difference in the battery life, the 3g used up a noticeable amount more battery.
screen brightness - this one i dont have too tough of an issue with, ive used the 100% brightness for a bit and didnt notice too much of a difference compared to the auto adjust.
IM applications - i used to have meebo constantly running until i noticed it wouldnt stay connected very well, then i found that if you lost connection it would try to reconnect for 2 minutes, if not connection after that it would just sit there saying no connecction and still eat the battery, since not starting it up i do notice better battery life, i keep it on the phone for when i do need it but dont have it constantly running any more.
web browser - Ive noticed a couple times where I had been using buzz or some other website and found my battery die fairly quickly, it ended up that i had a couple different tabs open in the browser, namely buzz and some other forum page i frequent. it seems these tabs were continually trying to refresh or something and just sipping off of the battery. what i do now when closing the browser is go into the windows menu and close each tab before exiting out of the browser by tapping the back button at the bottom
rogue applications - those crazy things....wanting to force close and crash and take your battery with it trying to process whatever endless loop they are stuck in. not to single out any specific app, things happen, but Ive had the last.fm app sort of crash while switching from wireless to 3g when leaving the house one time and it just wouldnt die, i had to actually reboot the phone, I could tell it was just draining on the battery since the phone was actually getting warm, as it does when its working hard or streaming audio.
tl;dr: I dont mind paying attention to what is actually running on my phone and charging it while im sitting at the office listening to music or always having it plugged in while using the navigation app....it is primarily a phone after all.
to answer your question, the att band N1 i have currently is a B and the tmo banding N1 i was using on att was an F, and in my opinion, they both have fine battery life depending on what I was doing with it along the course of the day.
I have this phone and the Nexus one. I can't tell you for sure what real world use gets you, but here's what I found today.
I had a class to go to. I took my MT3GS with me to the class. I have the HTC Flip Clock, as well as twitter, my texts, GPS on and minimal use during the breaks, and Silent Time Pro keeping it silent. I got home and my phone was at 96%.
My Nexus was left at the house. It has Beautiful Widgets updating the weather every hour. It has no facebook, no twitter, nothing that will sync other than my email. GPS and WiFi were off, as was the display. The only thing running on the phone besides beautiful widgets was Silent Time Pro. When I got home, I checked my N1, and it had fallen to 69% with absolutely no usage while I was gone.
Like I said, I dunno what real world use would get you on the MT3GS, but it seems far superior to the N1 at this point. All things considered, I think the N1 even with the faster processor should have fared better, as it wasn't used and basically nothing was on, as opposed to the MT3GS having GPS, a few things syncing, a few texts, and more programs running in the background.
This (to me) either means that A) The MT3GS manages power better OR B) Beautiful Widgets takes up far to much processor and battery power. Maybe I'll test it on my MT3GS later this week when I have some time off and see.
Anyway, there's my opinion. Take it for what you will.
I'm running the HTC flip clock, a few toggle widgets, the FeedR widget, Taskiller widget, and a calendar widget, and from fully charged to the end of my work day (few songs, few youtube vids, some texting, browsing facebook, etc etc) by battery is at about 25 percent.
I hate to say it, but my old Motorola Cliq would play Pandora through my entire work shift and still leave me with as much or more battery life than the slide does.
Honestly, not impressed with battery life so far.
My battery life has been ok, not great, some facebook, some twitter, a few hundred texts. some interwebbing. I can get around 10-12 hours from a charge it seems. which in my opinion is crap lol. i had a rooted cliq before this that was running only the basics in the background(killed all the bloatware and extra crap), i could get almost 2 days outta that thing.
I thinks once we get root and kill all the bloat and stuff running in the background, battery life will go through the roof. A vanilla 2.1 or 2.2 will prolly do wonders for battery life.
just my 2 cents

I almost feel like raising my hand and calling bs on 2 days with the cliq'r but i dont know you.
the cliq i used would get about 10 hours with use and 19 or so without use.
my g1 would get about 9 - 18
the mytouch 10 - 18
the old garbage samsung flip and sony flip phones 2 - 3 days.
this slide im averaging 10 - 12 with heavy use and 17 - 19 without much use.
keep in mind only had it for 2 - 3 days since release date but i did drain the battery and recharge it a few times the first day to break it in.
so far id say its about average on battery life.
i charge overnight
then either while driving, or working
then i connect to pc at home
with a full battery in the morning
and a slight top off mid day i never run out of battery life.
Hehe with my cliq I only had only the essentials running(there's a few custom roms out). So it went for almost 2 days. You can get the roms off modmymoto forums if you wanna check em out. The key to the cliq is killing motoblur =). Pm me if you want info shadow
I'm happy with battery life. First day I played with a lot, browsed a bunch and installed many apps and got around 12 hours(most I'd ever get from G1). Today I'm going on almost 24, took it off the charger at 4am after letting it fully charge, didnt start using it till around 10am and at 10am the battery still read 100% which I thought was wrong. Right now its at 17% (still havent gotten the 15% warning) at 1:30am, I'm sure it'll make it till 4. Sent around 50 text today, installed around two apps, and didnt do much voice talking or browsing but I did at least a good 30 mins worth from both. I periodically kill all with advanced task manager (except sense).

Amen. I carry a 3 in. USB to Micro USB cord that charges me at home, in my car and at work.
Those that are disapponted by the battery life are being unrealistic with their expectations. Power is too easy to come by to waste time *****ing about it. Makes you look too lazy or good to plug it in.

Sent from my T-Mobile myTouch 3G Slide
I purchased mine yesterday,and it sat on the charger overnight, and read a full charge in the morning.
6 hours 42 minutes later, it gave me a "battery life is at 26%" warning. WiFi, bluetooth and GPS were all off (all day)
I have it setup to check my email and facebook, but I had my Kaiser doing that and more for 2 days at a time with a smaller battery...
Usage-
55% Display (was set to auto)
32% Voice calls (20m 21s)
9% cell standby (6h 44m 59s)
4% Phone Idle (5h 10m 4s)
This seems absurd! If tomorrow doesn't do better, I'm taking it back.

.Realistic ... I never expect an electrical device that CONSTINTLY draws power to have a great battery, I dont race my car all day or let it idle in my driveway and wonder why theres no gas in the tank. a battery holds a resorce that regardless if yo like it or not .. will deplete over time. Advanced task killer is a great tool to get rid of th7e programs rnning in th7e back grond. to save batt life.
.Sorry for any mispellings, my laptops keyboard is taking a crap on me after it got rained on last night.

I don't think my expectations were high. Most people outside our community think "only a day" is bad battery life. I expected to be able to make it through 1 day without going dead. Being 3/4 drained after only ~20 minutes of talk time is absurd, especially since I didn't use the web or IM, etc. Just POP3 email every 30 minutes, and I uploaded 4 or 5 photos to facebook.
No Wifi, bluetooth, or GPS...
I just wanted to come back and reply now that I've had a couple days to play with the phone. I've been using it for about 16 hours straight now, quite a few texts, 5-6 short phone calls, and maybe 20 minutes of 3G usage, I'm at 66%. I haven't had this phone on the charger at all.
On the other hand, my Nexus, which has been on the charger all except maybe 2 hours in that same amount of time is already at 88%.
I think we have a clear winner in the battery life category. At least from my tests.
I am certain now that I have a defective phone.
I killed all running tasks, manually logged out of all IM clinents, etc, and then took it off the charger. I've made 12 minutes of calls today, it's only been unplugged for 4 1/2 hours and it's at ~%60 battery life.
12 minutes? Thats got to be a defect.
But, they are apparently out of stock... I might end up with a Touch Pro 2 or a HD2 after all...
Definitely not right .. I'm at 85 percent since 9am (7pm now), light use again though but its stand-by time is impeccable.. try and get another one, I can tell you the HD2 battery life is much, much worse, my father got it at the same time I got the slide and he's charging 2x a day. Mind you this guy would go the entire day with bluetooth,wifi, and gps on his G1. Oh and the usability of windows, well its just blah.. not trying to be biased at all. I have my brightness at 30 percent, syncng gmail only, and for widgets I have the curvefish battery widget, pure calander widget, power widget, and audiomanger. No bluetooth, gps or wifi on.
Have you tried going into the about phone in settings, and seeing whats draining the battery (click battery use)? See what cell standby is. Are you using 3g? May I suggest downloading anycut > new shortcut, activity, phone info. From there, open the short cut and you can adjust if you want 3g only (wcdma) or edge (gsm) only. Try setting it at one of the only settings, your phone might be dropping and picking up signal.
First post here, Hello World!
I have had mind for almost a week now. At first I was averaging about 1/2 day on a full charge. This was with Gmail syncing, no WIFI/GPS/BT on. Mild surfing, about a dozen SMS and 15 minutes of talk time.
I installed Advanced Task Killer and set it to shut off my apps on screen close. I am now able to go 17 hours ( a full day for me ) and I still have 15% left. This was with BT on for about 30 minutes of talk time, WIFI on for about 1 hour at the office, GPS on for clock/weather updates every 3 hours.
Overall, I am happy with the battery life on this device now. I am wondering if it took a while for the battery to calibrate and ATK helping with running apps.
I love this phone!

Sounds about like me. I don't use my phone to call much (go figure) but I listened to 15 min. of music, logged onto facebook for 10 minutes (3g) and sent probably 15 texts, and I was at about 65% in the 5 hours I had it unplugged.

Here's a question, Did you all plug it in and let it charge to full when you got it BEFORE using it?
Sure did. Ive made that mistake before, but I do that with all phones now, even though with a lithium battery, it shouldn't make that much difference.

Yea, I guess im just superstitious but I always do that with a new device. Have you tried recalibrating the battery? Charge to full, leave plugged in for like an hour after it says it's fully charged, wipe battery status, reboot, use normally? (if you can wipe battery status int he menu's without root) I'm picking my MYT3G slide up this weekend so I don't know if it can be done or not yet.
i think the battery life is great, i take the phone off of the charger around 9am. while im at work from 11aM-7pM i check my updates every hr or so. from 2-330 i listen to music also on my way home(7-8) and when i finally get back home round 8ish my battery is at about 58% then around midnight i get the 30% message. around 130-2am its at about 12% so i get 17hrs with medium usage
My battery life isn't too bad. 17+ hours since unplugged of moderate use (but only like 1% left): Display 41% (on Auto), Wi-Fi 25% (worked at home, kept on wifi for data instead of 3G), Voice Calls 22% (35 minutes; 14 calls), Standby 8% and Idle 4%. I think if you're more active in process management, it will help with life. I also just switched Brightness from Auto to a manual setting of about 20%. I un-synced Tweet and Weather and am running very few widgets, but keep GPS on. My K9 Mail syncs on an hourly basis and Gmail with Calendar and Contacts auto-syncs. Overall, MUCH better than G1.
Have you guys noticed any issue with the charging speed of this phone?
Last night when I went to sleep, 8PM (i know early), the battery was at 9 or 10 percent. I plugged it into the charger and all that. So this morning I go to remove the charger to check e-mail and what have you. 94%.... Come on, its 4:30 AM so that is eight and a half hours and not 100%?
Is this in the experience of anyone else? (Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?
Honestly, 8 hours to charge your phone does not seem right. Something is wrong with your battery. The vibrant does take a long time to fully charge, but never 8+ hours. It usually takes mine a good 3-4 hours when my battery is dead.
I highly recommend download the application juice defender. Research and learn how to use it. It will save you tons of battery.
I'm currently on my 38th hour since the last time I unplugged my phone and I still have 8% battery. Btw, I've been using my phone for phone calls, texting, and playing games.
First of all thanks for the JuiceDefender tip, that looks very promising.
But do you turn your phone off at night to charge? Because I just turned my phone off like 20-25 minutes ago and it popped it all the way to 100% just as I was typing this response.
Any other suggestions, tips, or concerns from anyone, please share.

No, I leave my phone on. Usually with Wifi too.
Also, I have a simple wallpaper that is mainly black (it has some blue designs, but the wallpaper is mostly black). Having a black wallpaper saves battery as well because the color black consumes the least of amount of energy from our screens.
Well my homescreen is pretty black. Black mesh background, black icons (bettercut). Black bar mod. Just got done configuring juicedefender, even bought the pro version. Figure if it doesn't work out I can simply return within 24h. And, I will know within 24 if it is helping the draining.
Leaving Wifi/Bluetooth/etc on will suck your battery down. Turn it on only when you need it. This is true of all smart phones.
My Vibrant will charge to full in a couple of hours from dead. I get 10+ hours on a charge even with heavy use but I almost never use Wifi or BT so YMMV. I definitely get better battery life from the Vibrant than the old G1.
Curious if you could pay attention some time when your awake... my phone rarely charges past 98%. Wondering if your phone is charging up to 94% quickly, and then hovering or if it's actually taking 8 hours to get to that point?
Maybe you should get a replacement.
I can plug my phone in around 10pm and at 6am my battery sometimes says 98-99%, but normally is good to go shortly afterwards. I do turn my phone off at night and those that need me do have my home number too unless I'm traveling.
As well I normal usage is 6am-10pm or so and I have typically 40-60% left on the battery depending on the usage. Yes I do check the About Phone and not relying on the wacked out battery meter.
I don't leave wifi, gps or 3g on all the time simply because I don't need them. Id rather squeeze the battery than have something on that isn't being used anyways. Having that quick settings drop down in the Notification bar rocks.
I have the same issue. It always takes about 4.5 -6 hours to 'fully' charge my Vibrant from <10% regardless of whether the phone is on or off. Then after unplugging the charger, the battery info states that the battery is charged to 96%. My belief is that there are firmware issues with at least some TMO Vibrant phones. I'm also dubious of the USB charger. I've ordered a regular charger and I'll see if my suspicion surrounding the USB charging system is founded. Maybe...

Is this in the experience of anyone else? (Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?

Mine takes about 3 hours to charge but I normally get about 13 hours a day on it with normal to serious use. I haven't had a problem with battery life since I purchased it but I have been trying new battery saving techniques to see how long I could make it last.
Currently using a mostly black background. Wifi only when I'm in the house. Brightness all the way up. Synching two email accounts and Facebook all day. Definitely getting the most out of the battery that I could expect.

Well mine takes a while but not that long. I'm going to try out the juiceDefender that was mentioned but the other thing I would recommend is the accurate battery mods that can be found in the Themes and apps section. You can flash with clock work and it's a great way to know what your battery is actually at so you can see how much you're using for various things.
Make sure your charger or USB port has high current output. There are some out there with only a few hundred milliamps. The phone will take nearly one amp and should charge in a few hours.
Excellent point. For me, I'm using the supplied Samsung USB to 110v adapter and I'm getting 4.5-6 hour charge times.

Also the USB cable is important too. 1 amp over a long, skinny 5 volt cable can drop the voltage. If the charging chip sees a lower voltage, it will think the USB port is at capacity.
I love this phone but I must be honest.. this phone is worst as the Motorola cliq battery wise. it's terrible. I had 100 percent battery life at 8am and at 10:50am I had 23 percent battery left............ no matter what I was doing.. even if I had the screen on full blast *i had it on the lowest* it still shouldn't be almost dead in 3 hours .... smh!

One poorly written application running in the background could be causing the CPU to wake up constantly. Yet I can talk for hours and the battery will still be nearly full.
I know for sure one of the latest versions of Facebook ate batteries like crazy. I ended up installing an older version and my battery life returned.
Update on the issue. I was using juice defender but it wasn't doing anything for me as far as I could tell. I have since turned off vibrate on touch, and noises coming on during clicking. I am using a usb hub with two vibrants on it. I'll plug it into the wall tonight and see how that goes.
I have been turning off my wifi when not using it. A little better I suppose. While typing this I went from 49 to 46 percent and I am a fast typer. No wifi bluetooth gps.

Yes the battery drains pretty fast, and it does take about 3 hours to charge... my main problem is... at night when I plug in to charge, couple hours later I get woken up by a beep and popup window telling me charging is done and to unplug...
anyone know how to turn that off?
Rather than clogging up other threads with my battery experiences, I thought I'd summarise where I'm at, and see how other people are doing with their battery life.
So I started yesterday on a full charge, and by 2ish the phone was dead. I used it fairly heavily, but wifi was off. I don't think I made any phone calls, and didn't use gps. It was mainly messaging and using the xda app. I had changed my screen brightness to auto the night before, so thought this might have reduced the battery life.
I then left the phone off, and charged through till just before 5pm. At this stage, the phone was up to between 90-100% charge. My intention was to see if I could get through to this afternoon on this charge. Last night I made a phone call for about half an hour, and used gps for about 10 mins driving in the car. Other than that it was a bit of messaging and browsing, but not heavy use by any stretch of the imagination. I had wifi off, facebook sync every 4 hours, and screen brightness set to about 50%.
This morning I woke to less than 10% charge on the battery, so have left the phone at home charging, and I'm back to my hero...at least for the morning.
I must admit, I'm starting to get concerned, because I really don't think I'm using this phone more than my Hero, and I could easily get a day out of it (unless I was going for a long run using some kind of gps app).
What are other people's experiences? I'm surprised I'm not hearing more about this, and I'm hoping mine is just a one off!
**UPDATE**
Today, 12 hours after taking my phone off charge, I have just under 20% charge remaining. The phone is now on it's fourth cycle, and although I haven't used the phone quite as heavily as yesterday, I have still used it quite a bit and have had WiFi on the whole time. This is still not amazing battery life, but it is still much improved. It definitely illustrates that the battery may take a few charge cycles before it optimises itself.
My first full day was yesterday.
WiFi on all the time. Screen brightness set to automatic. Twitter and facebook refreshing every hour. Weather every 4 hours.
Unplugged the phone at 7am, 100% charge.
During the morning I flashed the phone twice (due to the proximity sensor issue) so it probably recieved an extra 10 mins of charge.
Following the flashing, WiFi went straight back on so I could download all the apps again, and resync sense and all the contacts. There was some playing of games, some use of Google Goggles (so camera use there) and some web browsing.
By 13:00 I was down to 90% battery - which was pretty good I thought.
Through the afternoon I didn't get to use the phone much apart from a couple of short gaming sessions.
By 17:00 I was down to 80%. I got home from work and played around on the phone until my wife got home and we went out for a meal. The pub we were in had no signal, and I didn't really play around with the phone.
By the time I got home and went to bed, the phone was probably around 65% full.
So not a heavy day of use, but not far off a standard day for me - so not too bad as far as I'm concerned. Certainly about 30% better than my Touch Pro2 was!
I think we need to define a consistent way to measure battery life for Android.
Something like ACID test for web ... Quadrant for benchmark ...
I don't know, maybe we can agreed on something how to measure it. Or build an app to simulate phone usage which user should run it continuosly and then at the end got the result: Your battery life is rated 4 hours, 10 minutes straight using this test.
Probably not the best measurement, but it should give us a "number" to compare with other devices.
I can only suggest (I am not a developer), but I believe there are a lot of talented coders here in XDA which should be able to build this kind of "standard" app battery measurement pretty easily.
Somebody is recommending 3-4 full charges cycles for battery optimization. Do you think it will really help?
Battery is really deal breaking issue for me.
very helpful thread.
as mentioned few post earlier, there really should be a battery benchmark tool.
so was your wifi and/or 3g turned on the whole day?

My friends also lasted over a day with pretty good use, there seems to be better results with the brightness on auto...from what I have picked up on the forum...maybe a test is need to see how much difference there is between full brightness on one battery charge and auto on the other.
Yupe, the battery benchmark should not be so complicated.
Start the app with 100% Battery life
Some options in the app (for features that might NOT be in an Android phone or might not be available at the time?):
[ ] Turn on Wifi
[ ] Turn on GPS
[ ] Turn on Bluetooth
Set the app to WAKE all the time, display turned ON all the time of the test
Set Keyguard to OFF (device will not be locked)
Set Brightness to AUTO
Set all speakers to SILENT
Set vibration to OFF
Then loop until battery down to 5%, perform the below tasks in sequence:
* Play movie for 15 minutes [speaker muted]
* Browse to website??? be careful not to overload the website
* Doing arithmatic
* Doing 3D
* Play MP3 [speaker muted of course]
As soon as the battery down to 5%, app stop and display result ...
And of course restore all the settings.
The app should use generic API that is supported by Android, not some hacky wacky if you know what I meant.
Please if someone can code this, that would be very nice! Standard XDA Battery Measurement app for Android!

the app should log the result too.. since some phone is dead by time 5% due to calibration..
@Dazultra2000: I would almost trade the proximity sensor problem for the battery life you're getting!
In any case, I'm gonna leave my phone charging till half an hour after the green light comes on, then I'm gonna try another day of normal usage. I'm going to turn wifi back on, as I usually would, and set screen brightness to auto.
With my Hero I used to go for runs using a GPS app to log the route, I'm not going to bother trying that with this phone until I'm sure I can survive a day.

I don't know when you wake up but that could be like 14 - 15 hours that you mentioned which possibly isn't all that bad (plus the extra 10% you had remaining). Personally I want to see what it's like when you unplug it at 8am, not at 5pm the night before since I can't see any good reason not to leave the phone charging over night anyway.
If you then manage to get about 10 to 12 hours or so then there probably isn't much issue. Granted you weren't using it while asleep so the battery shouldn't drain overly quick but I wouldn't want to use your test as an example of a days use.
Thanks for the info but. If I was you I'd just have a car charger too if you like to use GPS...I can't see any reason not to.

Yeah, I would normally charge overnight, but since I had given a charge through to 5pm I wanted to see how it lasted....see if I could get through 24 hours. I wake up at 5am, so that was around 12 hours, with only 5-6 of those hours being time when I would've actually been using the phone. This is also bearing in mind that I had started yesterday on a full charge and the phone was dead by 2pm.
The GPS thing in the car was only to do a quick test, literally 10 mins. I need to buy a new car charger with micro USB, but I just made a note that I had done this because I knew it would affect the battery.
Anyway, we'll see what today brings.

Looking forward to it.
And yeah, for me personally a "days" charge really only needs to equate to about 12 - 14 hours. Thats probably the longest I'll go without having a charge anyway unless I'm camping or something in which case I'll likely fall back to a Nokia anyway.
Hi, just to add my experience with a complete different phone e.g. iPhone 3GS (developing apps on it, now switching to Android ):
Charge at night till 8 a.m. so 100% then usually in a day:
- Go to office, read/write emails, surf a bit on forums, blogs and so on
- Make call up to 30-60 minutes per day
- Play some games, test our application/games on it (so connect and receive some extra charge)
- Use WiFi at office
- Use Google Maps up to 15 minutes per day
- Back at home at 8 p.m.
- Use again emails and surf on web for 30 minutes
Around 11-12 p.m. it has less than 25% of battery, so 14-15 hours of usage drain battery up to finish it, not to mention that I'm forced to switch off push notification because they drain my battery in 5 hours!!!!
So just to say that, no one is perfect, and this devices today really do a lot of stuff, I think as Smigit suggest 12-14 hours are acceptable.
Have also tested/used iPhone 4, I don't seen any big improvements on that side.
Just my two cents...
praying for decent battery, please please please!
My HTC legend is pretty poor really, but I can live with it. If DHD is worse I don't think I can pull the trigger.
There is a thread in th Legend section about 1800mh HTC batteries (from another phone) that fit the Legend. Maybe there will be an option to do something similar with DHD.
I would pay £50 more for a 1500mh battery - why did they put the smallest battery in the largest screen?

No the battery doesnt fit with the Desire HD, if you watch some pictures of your 1800mah battery and than go and take a closer look at the DHD's battery, you will recognize that the pins of the DHD-battery are on its side. the pins from the Incredible Battery are on the bottom.
In 2 hours 30 min heavy heavy heavy use, the battery dropped 20%.
Will do a full day test 2 morrow.
I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.
Charging twice a day here. Its worse than my hero.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I noticed Yahoo mail and Craigs list apps I downloaded from the market have a memory/cpu leak that kills your phone super fast.

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.
Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.
Sent from my bathroom, with toilet paper.
I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.
def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me
Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.
getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.
Sent from my cm7 Evo 4G!
Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.
Sent from my cm7 Evo 4G!
Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
