my phone has been unplugged and used off and on for an hour now and I am at 84%. I've read people say they use their phones for 12 hours without a problem. I have tried 2 different batteries and its the same. by 5pm if I haven't plugged it in, it's dead.
oh good lord. it all depends on your usage pattern.
if you fill your car with gas - how long time car you drive it?
no-one can answer that question.

i used to only make it 6 hours on one battery. but then yesterday we found a new setting which i can now go 12.5 hours yesterday without even trying hard. go to *#*#4636#*#* and change to GSM Auto (PRL), this more than doubled my battery life. and you do not lose 3G, the phone will still use 3G just like normal. try it out.

I don't think I use it out of the norm. I check my phone when it notifies me of messages, come on this xda app and sometimes browse the web.... it's not like I'm streaming music, playing games or anything else a lot.
i too have found my phone dead in the morning when before going to bed was at 65% full. im still wondering the best settings for home and travel before switching to gsm auto prl because i dont want to drop totally dead when going outside 3g tmobile.
i also found my wifi is always on even if sleep. after i figure out this network deal ill do something with the wifi only being on when the phone is screen on and in my home. that will prob save me tons of battery.
I run wifi constantly on, the overnight drop is around 10-15%.
It should last 14 hours if you use 100 Ma of power per hour from a 100 percent charge to 0 percent charge.
I didn't know it was possible, but with IntersectRavens kernel (or whatever his name is lol) I can actually lose 1 percent of battery life in one hour (or close to an hour).
Though without turning my mobile internet off with Juice Defender's APN widget, this wouldn't be much possible. I found this very surprising, I thought people were making false claims about this.

Lol I must have exaggerated quite a bit. I was just astonished.. I don't really know how to explain my battery life I guess.. Its a day, and most of the night. Half of the next day might work as well if I didn't charge it through the night.

I should edit that post, shouldn't I.. four days would be impressive.
I'm gonna plug an app for this. It's not exactly the best thing out there in terms of an app killer (which from what I understand is a no-no anyway) but there are some nice little features that will really help narrow down some power use issues.
Do a search for SystemPanel and turn on Monitoring. It'll track when you have the phone on a charger, relative battery drain as well as device usage and cpu utilization all in separate histograms over time. History is saved (most likely in a log file) and can display from the last 2 hours to the last week. Without having to dive too deep into system settings you can track this info with just a few button presses.
I found out that using GSM Auto (PRL) and dropping the auto brightness and live wallpaper really did save a bunch as well and I was able to track the difference with the app. I also found out that playing too much Jewels will eat my battery like it was a cake at a weight watchers center.

i dont think anybody knows why or how that works. i'm still confused as to why it would even make a difference, but it DOES seem to help from my testing so far. today i am at 8 hours since unplugged, and still have 57% battery left, which is much better than i used to get. that's on pace for at least a 16-20 hour day which i would be happy if i could make it thru a day like that without having to charge.
Aren't there any explanations from Google about those settings ??

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?

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..."

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

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.

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.
Ive had my phone for a month now nad the battery seems to be getting better. Ive resently done a task 29 and updated to Artemis v9 with radio version 2.09 and from 4:30 yesterday afternoon I took it off charge its gone down to 90%. Thats doing light txting and web. Im amazed....
exactly the same experience for me, using the hd2 since december and battery now lasts almost 3 days from time to time
i even bought a second battery to replace it when im not at home lol.. but not that important anymore
and yea, im surfing everyday and text very much, some phone calls too, normal use..
i love it xD

I usually wait until it gets down to about 10% charge, then top it up.
But, it does get trickle charges during the week while plugging into my car.
i also found my battery getting better
with 40% brightness, from 8:30am online to surf web until 4pm, still have 40%
i think because it uses less cpu processing power and speaker sound(play games or movie), that's why battery can last longer
your probably find that a lot of it is down to how much you use it, Obviously when you first get a phone for the first couple of weeks your going to be using it constantly, figuring out new things and just general playing about, once you have gotten used to it you dont do as much, its not very noticable as its gradual but thats one of the reasons why battery life gets better.
83% now after a bit more txting and a little bit of facebook. ive been charging around 30 40%
I completely agree about the battery, I'm actually amazed
I am using Energy ROM with GTX and C00kie and I am getting a good 2 days of HEAVY usage, and i'm talking hundreds of texts, about an hour on the phone, couple hours of music, couple hours of 3G Internet with 3G on all the time.
I'm amazed.
Just run the battery out and then fully charge it and you're sorted.
Its down to understanding how Lion work.
They like being worked and the harder the better. If used like this over time they will give better and better results. There is no need to discharge or condition them in any way other than charge them as often and for as long as possible and this will maximize battery life over a few weeks. Then you see the benefits.

As we all know, the Galaxy S uses a Li-Po battery.
Having previous expirience with those batteries (R/C Helicopters), i know that they require 5-10 cycles of full drain-full charge to reach full capacity and start their normal life cycle.
Not too long ago, there was a thread complaining about battery life here, but i think it was due to people checking usage time on the first or second charge only.
In this thread, i'd like to hear your opinions about battery life, but please-
Only those who passed 5 FULL drain-charge cycles, reply. We need some objective information about it.
Personally-
I'm after my 4th charge, and already seeing HUGE improvement. When i recieved it i barely managed to go through a single day, and now i'm almost 2 days since i last charged it, played some games, browsed a little, made a few calls, and i'm still over 65%.
Waiting to do 2-3 more charges and reach optimal state to see what it's worth.
Mine is a Li-Ion and lasts about a day with almost constant use.

You are correct in that initially we were told the battery type would have been a Li-Pol.
However, since the phone's release it has now come to light that the battery is in fact a Li-Ion.
I made a post that mentions this here if you wish to have a read.
I’ve had my phone approx 2 weeks, so I’m on my 5 or 6th battery recharge. My phone has been on for 1 day 20hrs now. I’ve talked on the phone for about two hours and surfed for about ¾ of an hour. Wifi has been on all the time – Bluetooth about 3hrs. Current battery level is 70% - I must say after all the gloom and doom re the latest smartphones I’m more than happy with the battery life so far and does seem to be getting better all the time.

In contrast I have had my phone since Thursday... I've charged it 4 times in 48 hours so far. I am using it a lot and am hoping I get thee performance rise soon.
Crabby
I'm pretty sure it will.
When i got my phone i charged it to full, and before the day ended i needed to chrage it again.
And now:
Last charge was thursday morning (GMT+2), and now, after 2 and a half days, i still have 40%.
I could probably go on for another full day.
My first few charges barely made it through the working day, but now the phone still has plenty of charge after 24hours. Although right now is an exception, as the lady is playing Abduction on it and will probably keep at it until the battery dies

I got my replacement SGS today (had to send the original one back as Carphone Warehouse messed up the order so had to send everything back just to get a new SIM) and been hammering it for 14 hours, literally 80% of that running games, using WiFi, bluetooth and GPS and I only got it down to 25% and hadn't even charged it to 100% before I couldn't wait any longer. If the battery does get better after the initial charge, I will have no problem with this phone.
Further to my earlier post...
Charged the phone to full before bed last night... All of the power widget functions of two exchange email accounts and hotmail updating every hour.
So with no other use for 8 hours the battery was at 91% when I woke up. Battery status confirmed that 57% had gone on standby and 29 % on idle
So... Presuming this bsttery use is constant when idle... My phone will be down to 70 % by 24 hours with no use?
Crabby
It varies greatly according to reception.
Good network coverage= less work for the transceiver inside the device=less power drain.
It's not really constant.

Is this something you do as routine? I don't know if I have the patience to do that.
And my signal was 5 bar edge signal for my 'test'.
Since this morning, I watched 90 mins of video, surfed for 10 mins and made a 5 minutes voice call on the train... By the time I got to work, the battery was at 53%.
I don't feel my phone will last my journey home at 6 tonight, so I have had to put it on charge again.
But still... on 3 days old...

there are alot of mixed opinions on how to properly train a brand new battery, I'm talking right out the box 5 mins ago. Some are saying let the new battery drain and then start the charging/discharging and some are saying charge it right out of the box.
Anybody have a definite answer that has worked for them? Battery life has been an issue for me in the past and i wanna get this one right. thanks guys!
I charge it right out the box then do a full discharge and charge it back up again.
I think I'm a moderate / heavy user and I still get quite good battery life. Averaging around 20 hours before I need to charge.

It's Lithium Ion. You don't need to train it.
Android however needs to figure out how long it can run before the battery is dead. Charge it til it's full and run it down. Do that a few times and the OS should get a pretty good idea on where the battery is sitting.

yeah sorry for not being more clear, this is what I meant. not training the battery itself but the system so the battery stats are more precise
Wasn't there a special HTC-approved charging strategy that supposedly improves battery life dramatically? Was that ever debunked as BS?

you are not a heavy user then. I got about 12 hours with 2G only selected for most of the day. switched to HSPA. hspa+ 8megs killlllz my battery. I went from 70% to about 30 within a few hours just sitting in HSPA+ area and browsing and checking emails and facebooking. at about 12:30 that night i was at about 15%

You need to delete batterystats.bin from system if you get inaccurate readings. And yes, lithium ion batteries need no training. That was the older type nickel-whatever...

So, you're basically saying we need to train the OS, not the battery, am I right?
I always gave the battery a full charge and then let it go down to 0 and finally power down before re-charging. After doing that a few times I just did whatever as far as charging goes.
I also used to charge a lot here and there through out the day. I know only charge when it's low and I know I am doing a full charge. Not sure if it makes a difference with battery health, but I feel like I notice a difference.

Lithium Ion batteries should not have complete discharge cycles. Keep it above 40% when you can. Charge it regularly.
http://www.batteryuniversity.com/parttwo-34.htm
well I did the Evo trick and... i'm at 12 hours off the charge and 34%... that's with web browsing, texting, gtalk, phone calls, etc.
I think the GSM Auto (PRL) has helped a bit as my "time without a signal" went from 44% to 0%.
There are too many different answers from discharge at half, charge to full then discharge, and not let it discharge below 40%.
I think we should all test and log the different techniques.
So far
44 hours with light use
21 hours with normal use
15 hours with heavy use
and what I did was discharge at half and fully charge, also I dont let it shut down by itself and turn it off at 1 %.

This has helped improve my battery life significantly.
I have also noticed my signal is more stable.
I was on WCDMA Preferred before.

You can read all about it here: http://forum.xda-developers.com/showthread.php?t=670999
Okay, I read the post and did the evo trick, from my understand it stops your phone from constantly looking for a network.
while I made the changes, am I suppose to have "use only 2G network" check or unchecked? Also my connection changes from E to H all the time with this trick, is that suppose to happen because from my understanding it should stop it from switching networks?
I just tried the GSM Auto (PRL) evo trick.. now to wait and see if this helps at all..
Whoops, I didn't mean to imply that the evo trick was the GSM Auto (PRL) setting... I was talking about this:
To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.

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.
