Really don't know what is up with mine, unplugged 8h 30 mins, in the red zone now,

Usage stats:

Cell standby 35

Phone Idle 26

Android System 25

Display 10

Voice Calls 4

Usage today, one voice call, 3 or 4 texts, couple of text only e-mails and about 10 mins of web browsing, that is it... rest of time it has been in standby... gps off and wi-fi off whole time

If I use to playback music, battery is dead from full charge in around 1.5 hours... video around 1 hr..

How does usage compare to those of you getting longer life?
[Desire General] kinkade:
my battery life has started to go down by 1% every 20 mins and in psare parts it is showing the phone as running 100% of the time. i.e. never sleeping, under partial wake usage is listed android system.

so i figure android system must be a widget right?
[Desire General] JagSem:
Been using JuicePlotter for a bit over a day now and it goes some way into giving insight into whats going on. It seems when I use wifi it takes a nose dive. When it's idling its pretty stable. Although early hours of this morning while it was stable, the graph then started to plot a red line. It apparently was due to wifi connection. It can't have been possible because wifi was switched off and I was using apn. Looked into what apps were running and wifi-analizer was on. Killed the app using Memory-Usage and it switched backed to apn. Later on same thing happened but this time wifi-analizer was off. Something strange going on with the wifi. Battery barely last 17hours. Need to look into it a bit more

Any one with any thoughts? Cheers.
[Desire General] Tawm:
Android system is the OS it self, that's normal to have a bit of wake time, but other than that, something's up.
[Desire General] th3:
^^Out of 13h57m uptime, I have an Android system partial awake lock for 3m12s. And it's the highest partial awake lock by far, the other three are below 5s each. This is the highest I've yet seen it so something is up with yours.

u got any alarms set on your phone?

if so what times - i noticed a big dip when my alarms go off (although its fine now )

also check if u have push email on - then it could be sending and receiving email ?

For those seeing 100% to 90% fast;

WiFi on at max, HSPDA on at 2 bars, screen standby disabled with my normal setup (see above). Running a Stopwatch that took 15% CPU usage every second meanwhile browsing the web/typing replies through Chrome and the XDA forum app... 100% to 99% drop took 15m 43s. Non-stop use.

I don't understand. Yesterday, I unplugged the phone at 9u30. Around 18u, I still got 80% left while using the phone during 30 mins for calling and sending only 1 sms and occasionaly woke the system up to check some settings.

This night, I unplugged the phone at 2u, and set it to airplane mode. Still got 94% and this morning, around 7u40 this morning, I woke up and my battery life reduced to 59%...

When I checked juiceplotter, I see the battery life reducing this night at a really constant level, so there was no app that drains the battery... I don't understand and it doesn't make sense.

It's like that airplane mode drains the battery more...

Battery is another problem that any smart phone user must faced and make a good deal with it

[Desire General] kinkade:
yeah, it was 100%partial wake lock and running without sleep 100% of the time. but it only identified it as android system not as a particular app, so not hugely helpful in the diagnosis, i uninstalled tons of things but nothing seemed to help, so i have done a hard reset and am slowly reinstalling to see what it was.

whoever comes up with an app that shows exactly which app is using battery power is going to make themselves a fortune
[Desire General] Philosoma:
I closed all apps, turned off sync, gps, bt, and wifi. Phone went from 100% to 84% in 228 minutes, meaning 1% per 14.25 minutes, so just less than 24 hours in standby alone. During this time it had not moved at all and has a good 3 bars on 3G. Ridiculous! I love the phone but something is wrong..
[Desire General] Jazd71:
I had similar problem and found it to be the flikr app, i disabled the flickr app and ensured it wouldnt start again and sign me in then re booted and ive had much better battery life since. give it a go. Also check whats running under "applications" as sometimes the mail app on mine stays running after a sync and that drains battery too.
[Desire General] zkyevolved:
I charged my desire up for the first time today and I have to say that battery life sucks. Lol. I have two weeks before k have to return it if I don't want it for a full refund. But the device itself is awesome. Hehe. I have to go through the app store and see what other cool things I can do with this device. But the keyboard is rather small for my rather huge fingers. Lol.

When I got my desire, it struggled terrible with battery. Even got O2 to change it. Read every post trying to sort it, exspecially when I had a friend whos lasted 36 hours.

Eventually found it to be my emails. They was constaly connected to the internet, draining the battery. I changed it to check every 15 minutes instead and that solved the problem for me. Get about 36 hours now.
[Desire General] th3:
That's really bad, something is up. Check above, I get that much with nearly full use. Hitting the screen repeatedly with typing (touch and multi-touch drains battery quite obviously), loading and reloading many heavy sites, etc.

Maybe, just maybe... the large differences in battery times are caused by enabling/disabling autorotate and autobrightness as some of the factors. I leave both of these off. And both of them have to poll the state frequently.

i managed to get about 56h but that was when i couldnt connect to 3g :] quite few texts couple phone calls each day
[Desire General] jauhari:
It's almost 2.5 days? wow..

Are you connnected internet? browse some sites? check email?
[Desire General] Nightstalker79:
I lost 3g for the durations of 4 days due to a network problem and was amazed at how long it lasted the battery without, could probably get more than 3 days of moderate use without, but that is not what I bought the phone for. So nowadays I just turn off 3g whenever I don't use it.
[Desire General] Philosoma:
Some more testing.

Before bed I turned it to GSM only. Only had sync on for Gmail and weather (but is every 12 hours so don't think it checked in the timeframe). 100% at 0100, and 98% at about 0845. Juice plotter was a straight line! :eek: Even got some emails in the night.

In Battery page in Settings, the awake time is now a lot lower than the up time. This has usually been around the same awake/up time for me. Also the battery use page shows cell standby and phone idle as 46% and 47%. Normally it is the Android System with the most.

Most testing needed..

Is a shame no real toggle widget for 2G/3G.
[Desire General] foxmeister:
I installed Juiceplotter yesterday to take a look at the app. Personally, I don't do anything to "optimize" my battery life - I use the phone as I when I need to, and I don't regularly disable anything other than bluetooth when I don't need it.

Had it running for most of the day, and found that my battery was draining far faster with Juiceplotter enabled than it had done before - something in the region of 12% in 3 hours, even when the phone was not being used.

Last night I disabled Juiceplotter, with my battery at around 82%, and when I looked at my phone again this morning 8 hours later it was at 70%.

So, Juiceplotter enabled, I lost 12% in 3 hours, and with it disabled 12% in 8 hours. Not an exhaustive test by any means as you really need to run a proper test several times over, but I suggest you might what to try disabling Juiceplotter over night to see if it makes any difference for you.

Regards,

Dave
[Desire General] kinkade:
can you elaborate on what else has changed since your previous post when it was 1% every 15 mins as this seems a huge change in awesomeness, 2% in 9 hours! or did you go to bed at 6am?

keep us filled in we need hope, I've reset mine twice in the last couple of days as i had a runaway android system process that was stopping my phone from sleeping, i'm nor sure if i've diagnosed it yet so i'm afraid to start loading things back on, urgh.
[Desire General] Philosoma:
Basicly I just turned 3G off (set it to GSM only). In the last 10 and a bit hours, I've gone from 100% to 92% with sync and some light email use. Got a app that lets me change from 2G to 3G with about 3 clicks. Not ideal, but at least when I am out and about for the whole day I know how to save some juice now :) Maybe all these people with magical batteries don't have that much 3G coverage?

I shall also be getting a Veho Pebble thing when funds allow, better than a spare battery imo. Only £40 at most, and can charge other USB things devices.
[Desire General] kinkade:
thanks for the info dude, i'm not a huge fan of spare batteries either.
[Desire General] Nightstalker79:
Goto widgets

hit settings

press mobile network

thats the 2g/3g toggle
[Desire General] kinkade:
isnt that the 1g / 3g toggle, theres no data at all when you switch off the mobile network.

of course that might be what he meant all along
[Desire General] riz157:
I'm not sure how people can get more then 1 day out of fully charged desire. Unless ofcourse they don't use the handset at all.

Battery life plain and simple is awful on the desire but then again so is Iphone's infact it can be said for any other touch screen. This is ofcourse expected as investment in battery development hasn't been give nowhere as much priorty as the software development in the mobile industry.

I think this will change perhaps if the hype with the iphone 4 battery life is true.
[Desire General] Balos:
The other day I charged my Desire, let it plugged in for whole day. Next day I woke up checked the battery and it was already dowen to like 60%. Without me touching it at all.

The other day I did the same. Let it plugged in for a day without touching it and battery didnt go down much really.

Then on another day. I let it plugged in again and the next day approx 24hours. It was already buring orange again. The phone wasnt touched and it didnt refill itself up. I had to pull it out and in to get it filling again.
[Desire General] Balos:
thats what I dont get either. It should have a 10-14 days idle time. Mine has max about 3 days if it gets to 60% by day 1 when idling.
[Desire General] kmetek:
did you guys tried to lower brightness to 40-50% ?
[Desire General] Nightstalker79:
Quite possible, then again its the exact thing I was looking for when not using data anyway, with this toggle I could go for days of use, which otherwise just give me a few hours at most when 3g was on.
[Desire General] Philosoma:
If you want to just turn data off, use the Mobile Network widget in settings. Phone/SMS still work.

I have unticked the following for a good battery improvement:

Settings --> Mobile Networks --> Enable always-on mobile data

Juice plotter says 36 hours remaining on 70% charge.
[Desire General] th3:
The reason I don't use it is precisely because I monitored and logged the CPU usage and frequency with it enabled/disabled, and enabled it was keeping the CPU clock rate and usage pegged an average 15% higher than otherwise = quicker drain on battery.

How To fix it?
[Desire General] 6jaipur6:
i have 2,5 days battery life with htc wallpaper black, at the network only gsm, no automaticly update(weather,mail) only manual 3-4 times/day, i kill app like 4 5 times/day with normal manage programs, games 5-10 min/day and wi fi 20-30 min/day, calls 2-3hours/day...and that is all
[Desire General] jauhari:
wow that nice battery... can you list you installed Apps?

Mostly app that need Internet connection?
[Desire General] Sparksltd:
I have just sent my first HTC desire back and got it exchanged for a new one.

The reason I sent it back was because of dust under the screen and the battery life didn't quite last a day.

Iv now got my new HTC desire and I made sure I gave it a full 3 hour charge before use this time as before I unplugged as soon as it finished charging.

So far its really good! Battery life is a lot batter. Finished charging it yesterday at 4pm its now 7am and iv been using it a lot and its still 50%!

I also noticed I got a different charger this time with it. The one I had before slid into the plug adapter and always fell out! This time iv got one that twists in and is shiny black. It's much better.
[Desire General] JohnSteveDoe:
2.2 MCR v17, 62 apps

Widgets running:

Audio Manager on Home1

FB + Twitter on Home2

Settings toggle + Music widget on Home3

YouTube on Home4

Settings toggle 2 + FML + Calendar on Home5

Usually lasts over 24 hours with moderate usage (30 mins web browsing, 1 hour music, playing around with settings, uploading/downloading to dropbox, taking 5-10 pics, 5-6 calls, WiFi whenever at home) and brightness set to 80%, I think. I've never had it die before I went to sleep (wake up & unplug it at 7 AM), always charge it during the night.
[Desire General] ugmeme123:
what i did was i drained the battery and charged my phone for 8 hours, for 12hours of moderate usage (txt), my battery is 50%, what i find strange is it charges very fast.
[Desire General] veryjiggy:
Sorry for reviving an old thread, but I have experienced an amazing increase in battery life if I charge it overnight with the phone switched off.

Previously, I used to charge it with the phone on, and by the end of the day, I used to have roughly 30% left. For the past couple of days, I have been charging it from my pc with the phone off, and it has worked wonders. Have around 60% left by the end of the day with similar usage.

The problem of sudden drops from 100 to 90% also disappear when the phone is off while charging.
[Desire General] cgrec92:
Thanks veryjiggy for your post, I will also try charging my phone to my pc when its off, I always leave it on, will post results too :-)
[Desire General] andycted:
I'm really not entirely sure, but I think I've noticed the same pattern by using a battery recharged in a cradle charger, versus charging the phone on the dock itself while on...

I'm also on to discover if in fact push email drains more battery than pull, considering that my data connection is always on anyway.

Some more observations, hope to get some feedback:

- disabling "always on data connection", which is reported to save battery, didn't seem to have a big impact. Maybe because I'm 3g only ?

- disabling "auto synchronization" obviously had a bit of an impact

- changing advanced parameters in setcpu had a very big impact in my case. Especially by changing the threshold. At 80 it was really eating battery.

- live wallpapers obviously have am impact, but I've noticed that the blur by sense is a lot worse than a dark one as star field, surely because of amoled characteristics.

- juice plotter and some other "battery friendly" programs have a very big impact on battery life

- killing tasks is a waste of time, except the very rare case in which an application is somehow stuck, but generally the system pops the kill dialog itself.

- wifi seems to use more battery than 3g, but I guess this depends a lot on reception/usage
[Desire General] st0kes:
I charge my desire every night, and by the time I put it back on charge (usually about 11:00pm) it's down to about 50%. I have background sync on (gmail, corproate mail, twitter). I have screen brightness turned down quite low though, and I use Launcher Pro as a replacement for HTC Sense which I think makes the biggest difference.

Also ... I don't use any overclocking in the cpu ... imo it's not necessary with the 1ghz snapdragon.
[Desire General] Tiger33:
any evident that juice plotter wastes battery?

(juice plotter doesnt poll for battery information>?)
[Desire General] andycted:
In my case there were times when it prevented the phone to sleep. I also presume that, while not polling directly, there is some background activity because it showed a bit of cpu time when not using the phone itself.

Generally, staying away from any program that interferes with battery/tasks/memory and leaving everything to the system, looks to be better to _me_.

_me_ Underlined - very personal opinion.
[Desire General] Xinot:
Oh my... Heavy or light usage, i have not managet to get even 1 day out of my Desire. C'mon. Have to charge my phone twice a day. :eek:

I already tested like disabling all updates/widgets/3G/WiFi etc, and still if only i use my phone at all, my battery is draining fast!

HTC says standby time 340-360h, but my phone is using like 1%, maybe 2%/h when sleeping/doing nothing. I think i dont have battery with 340-360% capacity, or do i? :confused:

Anyways, i have read that froyo may drain battery even faster, so i just wonder how can i use my phone at all if i update it when theres something to update... :(

Do this sound like ok?

JuiceDefender to disable APN when screen off.

Disabled:

WiFi, Location (GPS & Mobile/WiFi), Auto Sync & Background data, Always-on mobile data. Using ADW launcher with no fancy widgets.

Usage:

Random manual FB & TW & E-mail refresh.

2-3 quick network visits via HSDPA

Some jumping around phone menus/settings

1 phone call 45min

2 quick photos

Here is what i get:

Android system 24%

Cell standby 24%

Phone idle 19%

Voice calls 18%

Display 8% (automatic brightness)

Dialer 5%

Camera 2%

Battery from 100% to 37% in 9,5h ...

Phone will get hot very fast too if i use HSDPA. I think it's not warming up so fast when i use wifi. Battery temp jumps from 30C up to 36-40C fast. It warms up there where sim card is..

sry.everyone.. i HAD to spill this out.. :D

Temperature & battery life

Yesterday, I got to 45,5 degree Celsium ... It actually burned into my hands. BTW my phone lasts only about 7 hours, no matter I do with it ...
[Desire General] qrees:
If your phone drains battery to fast check if you don't have some background apps running. Disabling WIFI, 3G, updates doesn't change much in my case and I get around 2 days on one charge.

Only problem i had is after installing some app which crashed in background and was using 100% cpu all the time. In that case battery lasted only a few hours. I suggest OsMonitor or "System Panel". After uninstalling problematic app, battery life got back to normal.

PS: sorry, but I cannot post links yet, so just google this apps.
[Desire General] michalurban:
Thanks, Ill check it out ... :)
[Desire General] Hasty:
I've tried everything I can think of and still have to charge my Desire AT LEAST 3 or 4 times a day even when I don't use it. I've tried two other batteries and it's still the same.

Oddly, I used to get a day and a half of heavy use before having to charge it. It's been steadily downhill since the last FOTA.

When trying *#*#4636#*#* the only thing that stands out is WiFi is using 100%/100% but turning it off makes no difference.

It's getting quite annoying now.
[Desire General] aindow:
Managed a day and 6 hours out of my phone on one charge.

WiFi on, 3g on, weather update every 3 hours, news update every 2 hours, Facebook every 2 hours, email twice a day, had 8 hours of flight mode whilst sleeping, and used the phone to send about 20 texts, 15 mins of calls, as well as about 20 mins general web surfing.
[Desire General] sandervanzijl:
I am still amazed by how much people use their phones and expect it to last for days on a battery.

what is this need to be connected all the time?

I do not have a desire yet, but I will certainly buy one in the next month or so. why? bacause i like to be able to search the internet once in a while, to have information available when i need it, for example when not at home or at work.

and to use my phone as a gps device/ fm radio etc etc maybe once a week.

otherwise it is 2 phonecalls a day (max) and maybe 3 text messages, and some weather updates.

maybe this usage profile is more realistic for battery life tests, since it it still basically a phone we are talking about. for using the internet all day, or a music player for hours you should use other devices. that is not the aim of a telephone. even though it is able to do everything the other devices do.

I am not saying that you should not use your phone as much as you do, just do not expect it to last for three days when you do. i honestly think that there is no mp3 player out there that will last this long.
[Desire General] michalurban:
I dont expect 3 days, but I dont expect 7 hours neither. 12 hours is acceptable for me, 15 hours would be nice, but less than 10 hours is kinda useless for me. BTW a friend of mine, having Desire for some 4 months, is regularily getting about 50% down after 13 hours off the charger - he synchronizes fb, weather, news, uses push email, surfs the web and listens to music ...

EDIT: Just received HTC response on this matter (and the temperature "issue"):

Thank you for your email. Concerning the battery over heating I can only give you HTC official statement: To make sure your phone is not overheating, please check the temperature of your phone via the onboard temperature gauge. To do this, you will need to download a HTC Widget that can read this phone statistic. Log into your Google account on your phone, if you have not done so. Open the Market Go to Home screen Tap All Programs/Launcher Tap Market Search for “Quietly Brilliant” and “Battery Widget”. Download and install this widget. Find an area on one of your home screens to place the widget, it only requires 1x1 area on any of your home screens. On first installation you will see a green battery with a percentage. Tap the widget Battery, the Battery widget shows the temperature and status of the battery. (Battery temperature will be displayed in 4th row with “Temp” and will be shown in Celcius.) Within 50 degrees Celsius is considered normal and within the specifications of the phone, meaning that the phone will function normally at that temperature.

Regarding your question about the battery standby times: The Battery Standby time is subject to network and phone usage, and the information we list in our User Manual and Website is under standard testing criteria applied to all Mobile manufacturers which is under specific laboratory testing environments different from your daily operating environment. this is why the figures on the website will differ from what you will experience in everyday use.
[Desire General] cgrec92:
i understand what you are saying

but if that is all you use a phone for then you are better off getting an old Nokia, there is no need whatsoever for you to buy yourself a high-end smartphone if you are going to use it for a couple of phone calls and radio once a week.
[Desire General] rolfd:
What rom are you using?

I'd say you have the wifi sleep bug, or you have an app that is keeping the wifi on all the time. Also check that you have the wif set to sleep after 15 minutes in the advanced tab on wifi settings.
