Ok, my battery is weird it doesnt last long. it dropped from abut 95% to 70% over night, with checking email every 30 minutes with k9 and the mail app every 4 hours. My phone doesn't last very long either, I haven't tested it fully. I always keep charging it, when im in the house.
I bought it from T-Mobile and i could swap it. Should I?

Might be worth it, I have Friendstream updating default setting, Googlemail (although it's push) on at all times, browsing a fair bit (on mobile net and WiFi) and a few calls and it last 2 days-ish...I'm using a generic Desire on latest FW
Mine's the same. I didn't think it would be worse than my old BB Bold for battery life, but it really is very poor. I don't think you have a fault, it's just the way it is.
I wondered about closing background apps but I've read that having them open doesn't impact battery life. I do have a few background things going on though that will affect it, so maybe I need to consider if I really need them or not (frequent email syncing, contacts/calendar syncs, etc.).

Have you put the phone down for long periods in-between uses, or have you spent a fair time writing emails or just playing with it? I've spent a fair time on mine but not constantly, and no more than I used to with my BB Bold. I used to writing emails constantly on my Bold and the battery would last a good day, but until I'm used to this keyboard I won't be doing that on my Desire.
So It won't make a difference if i swap it? I also didn't do the standard charge at the start. Couldn't resist playing with it. So It was on charge while playing with it. Could that make a difference?
I'm in work a lot and I'm not constantly on it - just check for emails/SMSs every hour or so so prob spends a lot of the time in standby. I'm on it more on the weekends but it still lasts well into day 2

If it works otherwise then I doubt there is a fault that would cause the battery to run down but nothing else not to work.
Not charging the battery at the start is one of those things that some say makes a difference, other say it doesn't. With Lithium-Ion batteries I always thought they didn't need that initial charge, but I can't say for sure. Anyway, what might help is if you did a full charge then a complete discharge (use it until the phone turns off) then a full charge again. With older batteries at least, that tended to help them last longer.
There a a few threads on this alread here and on the Android Forums.
There is a problem where the phone when charged left on, only goes upto 98%. However the phone will soon drop to 90% and lower quickly, indicating the phone has not charged properly.
If you unplug and reconnect, it will go back to 100% but almost as quick as tying your laces, it will go from 100 to 98% and continue to drop.
It could be faulty batteries.
I was hoping the FW update would fix but it hasn't as I found out last nite.
Or should I just buy another battery?
I've been having similar issues,
I get much much better battery life without mobile networks on, and alot of application crashes/phone reboots to get it work like I expected.
Took some data:
1hr of phone in sleep mode w/ mobile internet on = 4% battery
1hr of phone in sleep mode w/out mob internet on = >1% battery
So I can get a good two days if I don't have any internet with moderate use, but about 16 hours with internet always on and moderate usage. If I really 'rag' it and use alot, I can get about 50% done in a few hours (not constant use either, just alot of google goggles mainly!)
This coupled with the crashes and reboot made me get an exchange, I'm just hoping it's better, and really hoping its not worse..
Wish me luck, I wish you all the same.
After couple weeks my original battery seems to last longer - I do with 1,5 days now (with some browsing, 3G, occasional GPS and bluetooth, weather & gmail sync, dl apps from market etc). So it might be true that after the initial couple weeks of usage and charging the battery performs much better.
Intrestingly T-Mobile promised to send me a new battery over a week ago. As it never arrived I called them and was told they dont have any... but they would credit my account with £20 to buy one. Today... I received an extra battery from T-Mobile!!! No idea what is going on - and if I still have that £20 credit in my account
I will give that new battery a loooong first charge, see if it helps.
what about the 3000 mAH batteries?
Are they any good and would it work for the Desire?

Won't help, once it's at 100% the charging will stop. There is no such thing as 'long charging' li-ion batteries or 'trickle charge' a li-ion battery.
You can try to do a full first charge (until the green light burns) and then fully discharge (until the phone goes off). Then fully charge again. This will calibrate the battery chip and make sure you see the correct percentage.
If battery life is still no good then it's because you use the phone too much. Read: constant weather updates, friendstream updates, push mail and other stuff that constantly use the mobile connection. Also turn off gps unless you need it.
Turning off those services and turning off the 'always on mobile connection' can double your battery life (read: standby time).
It's not something magical, it's completely normal. If you want the phone to do a lot, it will obviously use a lot of battery.
Just for the sake of it, put the phone in airplane mode. You will be amazed how long it will last.
It's the main problem with modern mobile devices. Battery usage and capacity are no longer in good balance. What we need is more compact batteries that have more capacity.
At the moment it's clearly a comprimise between battery size (thus capacity) and battery usage. It's up to you to see how much you want to comprimise.
And so far, with every HTC phone, after a few (radio rom) updates battery life increased.
And... what everyone seems to forget, when you first get your phone you will fiddle with it.. a lot.. And once you have it for like a week or two, you start using it differently. Usually ending up with better battery life!
Try to run it down to around 5-10% after each full charge, but don't let it go completely dead if you can avoid it. Do this a few times and you will notice an improvement. Plus of course, when the novelty wears off and you use it less the same will happen.
Back when I got my Touch HD it would only just last a day, but by the time I was on the upgrade path I could get 3 or 4 days out of it!
Just to confirm, I was a bit worried at first about the battery life of the Desire. The first 2 days I could only manage to get 7 / 8 hours out of it. When I turned data sync off at night, it still lost 40% of the battery .. doing absolutely nothing.
However as mentioned before, I'm now on day 6 and now I can easily get 36 hours of browsing / texting / calling 2 hours + / even playing occasionally games. At night, without data sync, it drops just 4%.
So if you're worried about your newly acquired Desire's battery sucks, It really needs some calibration. After a few days it'll work as you wish.
T-mob battery
Hmmm.. Not sure what T-mob is up to. They promised me a £20 credit to by a battery (they didnt have any in stock) then I received the battery in post. I called 150 and they confirmed the £20 credit is still there for the next bill...
I couldnt be happier with T-Mob! Besides this I got 100txt/100min, plus 60 min included to Eurasia, Internet and 40 free txt to Europe = all for £10 a month!
Now I just need a case for it... waiting for the PdAir one to come, had one for my Compact IV and loved it. Its the flip one that opens upwards not down, so wont mess with the hardware buttons.

I really hope that's the case...
I got my Desire on Tuesday, first use was on Wednesday.
Yesterday (Friday) I put the Desire into Airplane Mode - I deactived everything. Turned off WLAN, mobile Internet, Syncing off manually before I went into that mode, just to be sure. When I went to bed, I had 72% battery left. When I woke up...50%...seriously, what the f...?!?!
8 hours of doing absolutely nothing uses 22% battery?! It's really annoying at the moment, absoluetly unusuable unless I'm home and know I can plug it in any second. When I'm out, I don't even dare to use mobile Internet, because even without it it only lasts till I get home (no WLAN, no mobile internet, just using it as a "telephone"...).

You expect the phone to stay turned on without using any power? This isn't a dumb phone, it is running powerful components and 8 hours doing "nothing" is relatively long time and the power usage of keeping those components powered at idle levels is going to add up no matter what. If you can't bear to turn the phone off if you can't control your usage, carry a charger or battery you should have got a dumb phone.
Bear in mind that the full capacity of the battery won't be reached until several charge/discharge cycles have been done, especially when you are using the battery for the first time on a new phone or on a phone with updated firmware. I noticed this while flashing custom ROMs on a previous handset. I'm sure we will also notice improved battery performance when firmware updates become available.

So you wanna tell me 20% battery loss in 8hrs airplane mode is normal? I hope not.

Hey all,
I am a new owner of a HTC Desire, have used this amazing device for about 2 weeks now. All is well, except for.... the battery life.
Here is my scenario, tell me if this is the "norm":
Unplugged from wall charger at 8:30am, by 9:16am (total unplugged time of 46mins), I had used 18% of the battery.
I had a 7min voice call, afterward a 2min video recording. While on the voice call, I had it paired to my bluetooth headset (Plantronics).
Power left in the battery: 82% (4021mV, 30.0 degrees celcius)
All the standard items loaded as part of the Android OS. I have no data plan yet, so 3G was off, WIFI was off, GPS was off as well. Lastly, brightness was set at 40%.
Is this normal? to loose 18% of my battery within that timeframe and also with the type of usage I went through?
Thanks or any response..!
It could be because your screen was on? If your battery is still bad after 2 weeks try to get a replacement.
I have learned to just accept losing 1% in 1min under heavy use.
I reckon I could empty the battery in an hour and a half with the right conditions. It just sucks, start carrying your usb cable round with you and keep an eye out for USB ports you can nick some juice from. If your lucky you'll get through the day with charge left and not lose your data cable (I'm on my fourth).
Some people claim to get several days use out of their desire. They must have a pact with the devil or something because the best I have ever seen is a day and a half.
This is the common issue for new Desire users, so don't worry its normal what you are facing..!!
-Trust me when i bought my desire i freaked out after heavy use the battery wouldn't even lost for 6-7 hrs..!!
-I had never got one full day out of my desire..!!
-So i did some serious research on this issue and came out with some Awesome solution..!!
-i have written the solution in my blog here:
http://harishanswers.blogspot.com/2010/09/disappointed-about-battery-life-of-your.html
-After reading that post ,follow the instruction that i have given at the last.
i hope you got the solution for your problem

- SetCPU: (Max 1036800, Min: 245000) Interactive scaling.
Not using the phone, while in standby it lasts basically forever. The longest I've gone without recharging is two days, light/none use.
When I finally recharged it the phone claimed to have about 60-70 % of juice left. Making a phone call would probably leave the battery with 40 %, LOL
Normal use gets me through the day with about 30 % battery at the end of the day. Ca 12-16 normal use.
Hard usage, my phone holds up about 6-7 hours time. When I say hard use, it's constant use.
Thanks for the replies everyone.
My situation hasn't really improved, even with a "app Killer" added to the equation.
like mercianary mentioned, I have been carrying my adaptor and USB cable where ever I go! Not the best method.
I am thinking of buying one of these to carry around..

Try using JuiceDefender. Should boost your battery.
Those tasks are close to the heaviest usage possible so nothing unexpected for a completely stock device. Battery drain is always subject to usage.
Albeit 18% sounds a tad high to me.
Did you verify you were starting at 100% and it didn't drop to 90% within seconds even with no such use (like experienced by many)?

- HTC Desire via XDA App -
Ive had my new HTC desire from 3 UK for a couple days now and although i had read the battery life wasnt great on these things im shocked how bad it is!
For the first couple days the battery was not lasting the day from a full charge in the morning so i decided to try the new leedroid 2.3a on it.
Still no better. The phone does seem smoother with leedroids ROM but from a full charge this morning 8AM to now 2:15PM the battery is already down to 30!! I have not really been messing around with the phone alot, couple of txt and a phone call but thats it.
Any tips on what i can look into to see whats killing my battery so fast?
Had same problem with sense roms untill i swapped to cyanogen mod. Running 6.1 with defrost kernel. Always have above 30% when i put it back on the charger, 15-20 hours. Used alot. Try a aosp rom. Guarantee better battery life.
Sent from my HTC Desire using XDA App
How much are you actually using the phone? I'd imagine you're on it quite a bit so of course battery will go down quicker
I also assume you didn't make a note of your original ROM version so you can go back to stock with an RUU if you decide you wanna send it back...
battery sucks...get used to it. sorry.
I've had a desire since may and i can count on one hand how many days my phone has lasted till bed time from a full charge in the morning.
some tips for you
3g kills your battery, 2g and sync on will use less battery than 3g and sync off.
get some power widgets to controll your phone, ie 2g/3g, sync, wifi, brightness, gps and use them wisely.
a bright screen on an amoled desire will kill your battery...turn it down unless you cant see it.
+1 for cyanogenmod
That is not true in all cases. My battery lasts more on 3G compared to Edge,not sure why. I experience frequent overheating as well when on Edge. 3G+WIFI Hotspot tend to last more than 2G+Sync.
I've been using auraxtsense for a while now, with browsing the internet, texting, maybe 20 mins of phonecalls my battery would last around 36 hours on a full charge, however i've gotten into the habbit of charging phones when i go to bed anyway.
I've left it for 3 days before doing nothing on it other than getting the occasional text message on some days off from work.
I've always been impressed by the battery life on Defy ever since I owned it. I haven't owned other smartphones before to be able to make a true comparison but using electronic devices for a long time I can tell the battery usage on Defy can be impressive. However, there were times I noticed the battery was drained so quickly.
In my latest watchful examination of battery usage I have achived to use only 30% of the battery for more than two days. Here is a summary of my usage in the past two days;
4 Hours Music Playback (PowerAmp)
30 Mins wireless
About 16 hours airplane mode
No phone calls on my mobile but I did dial a number several times
I have fully charged the mobile on Friday morning and on Sunday morning the battery has 70% charge.
Hint:
As it was stated in user manual it is recommended to charge the phone from mains socket whenever is possible. I can confirm that I've seen battery improvement after recharging the battery by mains socket after several times.
Since I don't have a use for MMS I have renamed the APN server. The same trick can be used to disable data and that saves battery life too if you don't use your phone to push/pull data.
In the past 2 days my network type has been set to 2G only. The automatic setting certainly have dramatic affects on battery.
Before going to bed I put the phone to airplane mode since the reception in my bedroom is very weak and this increases the battery usage.
With simple measures the battery life can be extended (noticeable) more than what you'd expect.
I'm very pleased with the battery usage so far. Nonetheless, I will buy a spare battery as soon as it is available in the UK.
Happy New Year XDA
Yours are the most impressive stats for the battery use. I've set my Defy into saver mode, and the network data to 2G as well (I only use it to sync up with Gmail (plus Calendar and Tasks) and my employer's Exchange email) and get down to 50% after two days of moderate use, which is enough for me not to worry about running out of juice if I'm away from home for a few days. Yes, the Defy can be pretty frugal with battery use.
I ended up having my original Defy swapped because of concerns that the battery wasn't up to scratch and the new one's been brilliant.
I'm in 3G all the time, never put it in airplane mode, and after 62 hours I still have 20% left - that's with me having used it for some calls, texts, web browsing, facebook and a good couple of hours of Angry Birds as well.
Definitely the best smartphone around for battery life IMO.

What does mains socket mean? The wall outlet (I am in the US).
If so, how else would you charge? Computer USB?
If its the bit in the wall that the electricity comes from then its the same thing :L and yeah you can charge it from a computer USB but it takes a little bit longer

Yeah, seriously.
I'm not talking about hours of calls, more like 15 minutes or so. Maybe an hour or two total web browsing and facebook and perhaps an hour on Angry Birds.
Part of the reason it lasted so long was that I just didn't touch the phone on Christmas day at all, so that was 24 hours with basically zero use, which is unusual.
The next charge last more like 2 days, which I think is closer to how I'll be using it normally.
if you put it in air plane mode, and a couple hours later u turn air plane mode off. will u get all of your notifications? like calls,texts and stuff that people sent to u while the phone was in airplane mode
There is true gem on the Market named JuiceDeffender Beta - I used it since my Milestone and it really does what it says it does. All the hints you mentioned already included in the program and are being controlled by it. For example, as soon as you display turns off your network automatically switches to 2G. In paid version you can even adjust processor's speed when needed (underlocking of course, in terms of battery saving) However i am currently on free version and it's enough to make the battery last almost twice as longer.
I had some problems installing it on Defy, but they were all gone as soon as I rooted the phone.

How did you get the 3G -> 2G to work? I can not enable that feature, as I am not using a CyanogenMod rom and I can not download/install AOSP helper as it suggests. I am using the beta and UltimateJuice, which I purchased after seeing what features it provided. I'm using the CPU features to do what SetCPU did for me - no need to have two packages with overlapping features installed.

In practice the only ROMs known to work are CyanogenMod (any version) and the Nexus One stock ROM..

Hi
Had my phone a little over 24 hours and I may have a very poor battery
I have a LIVE screen on the one with the water and the leaves plus, I haven't made or received any calls but I have used it a little for internet and a few text messages
The green bar was on full about 5 hours ago and if I had to guess how long my use has been I would say 30 mins in total of the 5 hours, now my battery is indicating less than half full
Imagine if I was out all day making and receiving calls?
Does this sound normal?
This is normal for the first week or two , the battery is adjusting itself to your needs
Sent from my HTC Desire using XDA App
It's absolutely normal and you'll really notice a difference in about ten days, a couple of weeks the most.
That said, live wallpapers do use more battery. I much prefer a static dark one
adding to that make sure your phones nicely drained before recharging to ensure you get a nice full charge for next time... i took my desire's battery at least 5 days to start having a long term charge
bettery
same here took a week also what really helped me is having advanced task killer and setting it to kill unwanted apps after i lock the screen
i dont think you should use task killer, the apps will end them selves, i used task killer and got alot of force close after and errors etc
however force stopping unwanted applications is also good.

cell standby 25%
phone idle 17%

5 H 55M 55S unplugged, hahaha no joke its all 5's
and now my battery is almost dead surely this cant be right
has anyone ever been given a replacement battery for their phone or do they ask for the phone to be returned if this is infact a fault
Battery sucks, phone is power hungry. Get used to it
I've had 2 desires since a week after it was released, i can count on one hand how many times I've got through a day without plugging my phone in.
I get about 2 days on my phone if I don't mess around with it a lot or get many calls. I normally plug it on overnight. Every night.
Nowadays that seems normal for a smartphone. Personally I think the battery life is slightly better than the iPhone 3GS.
Angry Birds means it lasts about 4-5 hours...
Sent from my HTC Desire using XDA App
It's all down to how your using your phone. If you have a live wallpaper and many widgets and apps that run in the background like running in the notification bar, then yes, your phone will die pretty fast. Also it depends on how much CPU your burning. When I first got my Desire, I was like WTF. This is useless battery life and was starting to play hell. Now it's fine. I can leave it for 2 days easily if I just text or flick through settings. It just depends on what your running.
BTW, no one should have a task killer. It defeats the purpose of Android. You can get a lot of force closes and other things. Just leave them alone and let the OS handle the apps. Android does end the process if it's idle, eventually, but it's not using anything really other than a bit of memory just to keep it going a little.
As GoogleJelly pointed out, it really does depend on what you do with your phone and what's apps/processes are running on it while the device is using battery. Even I found the battery life pretty poor at the beginning...I found it quite annoying having to charge this thing nearly every day.
After some light tweaking, I managed to get the battery life to go over 3 days and I now have no reason to complain about my phone Mind you, I'm not a heavy user....As for background apps, I think i've got about 5/6 apps running at a time...
EDIT: I've attached a screenshot of my battery meter.....
What app are you using to view your battey history?
I also tested task killer when I got my phone. I thought it was fixing battery life, but after bedding the phone in a bit I took it off to see how much difference it would make and I didnt notice any difference at all...

I configured Quick Battery app to go to battery history from my phone settings every time I tap on it. You can view your battery history through:
Settings > About phone > Battery use.
If you want the graph, just tap on the top layer which shows the length of time you've been on battery.
EDIT: This works for Gingerbread based ROMs (it's the standard feature lol)...can't remember this being on Froyo.

This is irrelevant with Li-ion as this is a myth from the ages of NiMh batteries. Your battery will not get ruined if you don't discharge it completely before first charging.

Ah right, cheers for that. Didn't know it was all built in
One of the main reasons why new smartphone owners experience fast battery drain lies in the simple fact that they fill up seven homescreens with widgets that sync over mobile internet every hour or even more often, which really kills the poor juice like a massive gas leak.
After about half a year of use I've reached a stage where I use just 2 screens on my Desire (CM 6.1.1), of which page no2 is a full 4x5 agenda and Page one has just one actively updated widget (home weather).
Combined with restricting network usage of random apps by means of DroidWall and underclocking the processor at certain parameters (eg. battery <50%) the phone lives for 2 days pretty easily, with moderate browsing, music etc included.
But TBH I've really decided that the battery usage is absolutely random because some days it just drains like there's no tomorrow with no apparent reason that I've been able to identify. Carry a spare microUSB wire tbh :/
I read so much myths in this thread concerning Li-Ion batteries.
First of all Li-Ion batteries do have instantly the capacity they are intended for. Even 5 charges won't change that. The only thing which can change over time and charge-cycles is your phone recognizing a new voltage level as "full" (read more: "calibrating htc desire battery") or you playing less with the phone or having power-consuming apps uninstalled.
Also a full first charge is not necessary. This "requirement" are from past days with NiCd or NiMH battery-types.

The calibration during the initial week or so of using the phone arises from phone-side calibration, not the battery itself, which is why deleting battery stats from recovery can at times resolve battery issues :V
Phone didn't last half a day after flashing CM 6.1.1; after a couple of days I charged it to 100%, deleted the stats and voila, it's about as perfect as a terrible smartphone battery can get.
