My phone's been running for 16 hours and 20 minutes on one charge, and the battery is at 59%. Not entirely sure if this is impressive or not, but I figured I'd share my settings. I'm on CM7 Nightly from the 13th.

I like the SetCPU settings, I have never messed with the profiles before but that looks like a good idea.
I will see how this goes first then maybe try JD.
Over night my phone finally got down to 1%. Topped out at 31 hours 20 minutes or so.

I'm monitoring with Current Widget and i'm noticing that my phone is deep sleeping and pulling down to as low as 1mA sometimes! I usually get about 24hrs or so, but I just applied some different setcpu profiles.
I also use Tasker to shut off mobile data in the middle of the night, then turn back on in the morning. I think it's pointless to leave it on and waste battery life while I'm sleeping.
Im going to try out Juice Defender. I had itw ith my Aria and it does work very well at saving battery life BUT on that phone it would cause some lag when switching networks on/off etc. On this phone hopefully it's fast enough to not notice the lagginess when switching networks.
I just did some major testing of the inspire power draw, and you guys are lucky. Compared to my nexus one, it is super efficient. The highest with screen on and pushing the phone hard, current would max at 400mA at max brightness. At 50% brightness current was steady at 230mA no matter what.
In comparison, my nexus one spikes to 700mA when showing white web pages, and around 180mA showing black. These spikes aren't good and no wonder nexus gets crap battery life.
I can see why they under spec the inspire battery, but I wish they didn't.
I'm going to try out your settings for a few days and see how it goes. Thanks.
Would you mind sharing the link for the juice defender. I've downloaded the newest beta and it says it cannot disable the cellular radio because it is not fully supported. Note I did flash it using the kernel with the battery fix posted on the forums. Do you think that could be the problem?
I just use SetCPU profiles and JuiceDefender in default mode. Immediate difference in battery life.
For testing purposes of CM7, I would leave my phone off the charger to see if the battery fix was working. Normally it would drop 15-20 percent sometimes more. With the SetCPU and Juice Defender, Just dropped 8 percent. WOOT!

I've been using HTC Desire s just for 1 week, it's good device but can't use a day after full change morning. I hate the battery life iphone but it is worse. Do you know how to get the battery life better this HTC Desire s ?
I've done 2 things like below.

2. Once full charge after battery dead(100% consumption)
Any better idea ? Thanks in advance.

Same to me. 30 hours is max. This is not very good....
I also have the same as if I leave my desire S in stand by for 6 hours it loss 50% of charging and I sure that everything are closed (Wi Fi , Bluetooth , GPS , data connection , Application) so pls can anyone advise if this is special problem on my phone or it's generally in all Desire S
I find the battery quite good actually.... I normally charge it over night and have at least 25% left, normally towards 50 depending on how much angry birds i played

I'm getting around 30 hours before my nerve goes and I charge it up again at about 25%, but I'm still using the phone quite a bit more than the dumb-phones I've had in the past.
Check: Settings > About phone > Battery > Battery use
Essential apps:
Battery Monitor Widget
Power Monitor Widget
Screen Filter
I have the screen set to auto brightness, but use Screen Filter to reduce the overall brightness to (say) 50% outdoors, 35% indoors, and 25% in the evening.
I find the biggest drain on the battery is the display, but maybe that's because I've reduced a lot of the syncing.
In "Accounts & sync", I've disabled syncing for most things, especially HTC Sense; Weather widget updates every 3 hours, other things every hour or so.
WiFi is usually off, though even when it's on, it doesn't drain the battery much.
I get the worst battery drain when playing games or watching video, especially with the brightness turned up.
GPS is enabled, but rarely in use. 3G coverage near me is poor, so I'm usually on 2G only.
[ duplicate post got created somehow when editing - can admins delete this one? ]
Try these:
-wifi settings advanced setting for sleep after 15mins
-usb debugging on
-cancel auto sync OR sync frequency for all those things that like synching all time
-change email sync (default is every hour)
-change weather update
-turn off gps
-screen sleep quicker
there are some apps which are poorly put together and can drain battery, i had problem with android market fault and had to reinstall it, also 3g watchdog had an issue before
the desire s battery is better than most android phones, certainly one of the best compared to other htc phones so battery life shouldnt be an issue..
I get two days use. I consider myself an average user. Calls, sms and internet browsing.

Don't use Screen Filter unless your intention is to reduce glare when using your phone in darkness. It will not save you any power if you are using an LCD display. and

If all you do most of the time is idling, it should last a couple of days.
My experiences:
I always using all features in mobiles such as localisation, 3G, wifi, synchronization always on. I'm doing this because phone is for me/I am not for phone
Some stats on Desire S:
-wifi only(mobile network off) 60 min of video, 10 mins voice calls, few text, few emails, few webpages 50% screen brightness
result: 27 hours
-wifi off(mobile network on) 60 min of video, 10 mins voice calls, few text, few emails, few webpages, 50% screen brightness
result: 22 hours!!!
Cmon HTC, this are very bad stat!
Anyone know is that good stats? Please don't tell me to switch off this and that...If We will be thinking in this way maybe we just put mobile on air plane mode, set birightness to 20% and then We will get around 40 hours.
Do You think, that custom roms can help with it?

Of course I did. I always doing calibration even if now is not necessary...
I have WiFi, BlueTooth, 3G on all the time. Sync on and the device is in background alone collection app. 3MB of data.
If I don't use the phone, then it uses app. 15-20% of battery a day.
I can use the phone app. 5-6 hours a day for browsing, install programs etc.
I thing that is a full days use.
I have turned off auto brightness, as I don't think it is working. In normal day light I set the light to 50% which is nice for the eyes. (Auto mode goes to almost 100% all the time, which uses more power.)

What settings do you use for Juice Defender. I've been messing with this app but is unsure on what is the best settings to use.
I had it on balanced and it said it was saving me 1.22x batterylife and one day I switched it to custom and I swear I changed very little and now it shows 1.89.
Give that a try.
I am a bit skeptical on these battery saving apps. They run in the background, using more memory and battery.
I'll mess with it a bit more...

I only use Juice Defender to shut off mobile data when Wifi is turned on and when certain apps run... otherwise, I dont let it shut off my data or wifi because the phone has fantastic battery power, so I let it stay on 24/7.
I use it to turn WiFi and data on or off by location.. night mode and on custom stewing and get about a day and a half on a charge with pretty heavy use

Sent from my HTC Sensation 4G using XDA App
Actually juice defender does a very good job for the battery life mainly on stand-by. If you are unsure of the settings i suggest using the ,,balanced,, option. But here are some of my tips (i use a lot of 3g internet on my phone, so the settings are a little more internet-permissive )
About tab: I selected here turn data network on screen wake-up ( i use the friends stream network, mainly for twitter updates and i like to have a 3g connection rigt after i wake-up the screen (default is turn on 3g when you unlock)
Control tab: I didn.t change here anything, the default settings are good
Schedule : I choose some peak times here ( from 12 - 16 weekdays) when the 3g stays always on, even if i turn off the phone - i recive alot of emails during this time (also i set up mail peak times during this interval to 1h update)
This is what i changed on my device. It may not suit you or any other user, but as i said, personally i noticed a good change in battery life in standby (this is what Juice Defender actually does by turning off data connection when not needed, simple but effective)
I use the dim screen option, set at 55%, and min at 80%, max at 150% and enabled the dimmer option under about
I'm using mainly the default settings and so far so good.
The only issue i have found is that i could not install an .apk from SD card when juicedefender is active. I had to disable it in order for the "install" button to work! Any ideas?
I love juice defender, it says it gets me 1.90x more battery.
i use custom setting and i have night time where it disables most things between certain times when im asleep, the apps i tell it turn things like twitter and stocks not to access internet at all, as i dont even use them.
its very clever and i have just looked at the advanced options and there is so much more you can do. need to learn a bit more about it before i used advanced.
Thanks for the replies. I'll mess around and test it a bit more.

I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.
Thanks for all the advice this has really helped my battery

There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

I found that juice defender helped my battery and i just use the free version it's a great app

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.
Syncwifi application is awesome for extending sync settings to gain more battery

JuiceDefender!!
I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.
I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.
I've only had my nexus for a week now and I'm trying to hunt down the reason I'm getting poor battery life. At first it was nlp wakelocks but that went away on its own somehow. Now its my wifi draining battery, in 8 hours of idle overnight it went from 100% to 79% and wifi was the top usage. I've never seen this before on any phone with any rom so I'm not sure what to do about it.
Hi,
Try Settings/Wi-Fi/Menu/Advanced/ and untick Scanning always available...
This is what I did to improve my battery:
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email. Another thing I noticed was that some widgets are just more battery intensive than others. For example I found HD widgets consumed nearly twice as much battery as Chronus on the home screen but both displayed the same information.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
