I have a widget that shows me how much I have left and when I unplug it after a full charge, I have 6 hours left.
Ridiculous.
This is on auto brightness, wifi, twitter/facebook/mail updating every 15 minutes.
whenever I take my phone out the house I have to bring a charger...
bloody ridiculous.
couple of points.
1) When you leave the house, don't leave your wi-fi on! I find wi-fi to be the biggest battery drain out of everything ( expect gps)
2) I use a brightness widget, therefore when your in doors you can have it on low, then when your out doors have it on high, i assume this will use less battery then auto brightness
3) why do you need facebook updating every 15 minutes?? Do you honestly look at your phone that much when your out? change the settings so it updates every 15 when your on wi-fi at home, and every hour for when your not.
Wifi isn't an issue. I leave it on 24/7 as well as bluetooth and still can get 36 hours out od a charge. Its hooked up to wifi 20hrs a day as well.

1. Battery and other constantly updating widgets are one of the causes for battery drain. Get rid of it.
2. Battery widgets try to get an estimate of your typical use. They are mostly wrong in my opinion
3. I can get 6 hours of battery, yes, but only if glue the phone to my hand and use it constantly for that time
4. there are tons of battery threads around, use those suggestions (mid brightness, no live wallpaper, turn airplane on when you know coverage will be unavailable for long, etc)
5. Battery gets better in 10 days.
6. Most people can get at the very least one day of heavy usage. If you really need to hammer the battery get a spare one, they are cheap. Oh, and realize you are lucky because you CAN have a spare battery !
7. If you are using an automatic task killer, get rid of it.

1) go to the market and search brightness level, or brightness widget, there are a number of these. The best i find is brightness level by curvefish, it lets you pick a percentage and keep at that .
2) Cant remeber actually where the settings are but there is a way. But i prefer to use another widget, autosync on/off, this allows you to update every 15 when on wi-fi, but when you want to save battery, turn auto sync off and it doesnt sync ,
I suggest you use switchpro widget. its like the power control widget but with more options to turn on/off things.
I typically charged my Nokia N97 every other day or so, even though I used it frequently, and needless to say the HTC Desire doesn't have the same stamina. I was quite frustrated by it, and I started thinking of ways to save power. I came up with 19 tips, and I have actually noticed quite a difference by following them
19 Tips to Keep the HTC Desire Running a Little Longer
Nice post thanks.ill give this a go. But I have a question to do with the positioning using data or gps. I believe your stating that you should turn data off for this purpose, and let the gps do it? however my phone was set to opposite. when I changed as you were suggesting and I clicked allow gps, I had a message come up saying to turn off to conserve battery? But your saying to turn on? And have data off? Also how do you get into htc facebook settings,i cant even find it!

yep i also use this widget
also use a free juice defender or paid ultimate juice that keeps turning on and off your 3g every now and then depending on how you schedule it, my phone with snowstorm weather widget updating every 80 minutes + 30s of 3g every 5 minutes to update mail etc and average usage lasts about 36 hours which is good enough for me
I leave my WI-FI on at home and suffer hardly any drain.
At work like today leave my Mobile network on down to 47% with just twitter usage!
Pathetic is the mobile signals drain.

Ok, ive had another read of this and am now just even more confused! Are you saying to have gps turned off via settings and location aswell as data, or just having gps on? Are you saying that having gps selected via settings for the purpose of locating services uses les batty than via using data? Either way, it appeatss that the power control widget controls the gps the same as via settings. Right now ive deselected gps and the data location.

I believe this is what I'm saying:
"To let your device learn your location via wireless network triangulation requires less battery than by using the GPS for this purpose. However, using both methods simultaneously is probably not a good idea from a battery point of view. The GPS can handle this task by itself, although it will get a fix on your location a little bit slower. Also, wireless network positioning will be used to collect anonymous Google location data, which will drain the battery further. You can change this option from Settings > Location > Use wireless networks. "
In other words, to only use wireless network positioning will supposedly use less battery than by only using the GPS, but using both methods will naturally use the most juice
For me...
- Turn GPS On when I needed.
- Turn WiFi On when I needed
- Turn Bluetooth On when I needed
- Use 2G Network for standard internet, we use 3G if we want more speed such us watch video

I can get get good days heavy usage (except games) from mine, I haven't tried the 2G thing yet.
Apparently it is the connectivity thing that kills the battery, but turning off 3G, doesn't that take all the fun out of it???
If you just use it as a phone then I reckon you can get a couple of days out of it, or so I've read...
I've been trying to troubleshoot my battery drain rate and I found the problem.
When I turn off the GPS, and leave the wifi and bluetooth on, I get tremendous battery life/
What could be causing the GPS to drain the battery?
Do you ahve any programs running in the background that use gps? such as latitude, or that google one that maps your location? If so, gps kills batteries, because it constantly resyncs with the satelites... I believe the sense weather app also does periodic polling to pinpoint your location for weather.
If you dont need GPS exact location tracking, dont leave gps turned on, and turn it on when you need it.
My GPS is always on. It doesn't really hurt the battery life unless you are using with an application that uses the location service. My weather widget is set to refresh every hour and it's not impacting the battery.
I would look at your running programs and figure out which one is using the GPS. If you have the sensorly 4g map viewer, I found that to be a battery hog.
My money is on Latitude, that's been implicated in a lot of these situations. GPS always on is hardly a battery drain unless something is actually using the receiver. If you don't see the GPS icon in the notification bar, it's not GPS-ing.

Interesting tip. I had not noticed it. Thanks.

I have my GPS on all the time and I regularly go over 13 hours without recharging; this is before SetCPU and underclocking.
As for those who don't know. There is an app out there called tasker. It allows you to program all kinds of tasks and conditions.
I used it in froyo to turn on my gps automatically when I opened the navigation app. However in gingerbread tasker no longer works. I'm reading that in cyanogen gingerbread roms tasker can still enable and disable gps.
Does anyone know anything about modding EI22 so that tasker will work with gingerbread on our epics the way it does in the cyanogen gingerbread roms?
Is there a patch or a piece of code that can be taken from the cyanogen rom to allow this on different roms/kernels?
Possibly is there an alternative to using tasker to get the gps to turn on automatically when navigation/maps is opened?

Just leave GPS enabled at all times. GPS won't activate until a program needs it, and won't consume battery life while it's sleeping.

Cool. I kinda thought that, but I wasn't sure. I guess ill need to turn off location settings for all the apps I don't won't to access gps. I appreciate the info. Thank you.

To go with this, if the GPS icon is on the toolbar (generally a bullseye/crosshair looking icon), you're using GPS and therefore extra battery--on the flipside, if the GPS icon is gone from the toolbar, then GPS is in standby and not consuming battery.*
* I'm not entirely certain that it consumes no battery when in standby, but it's certainly much less than when it's active. As long as you keep an eye on which apps you allow to use it and when, the battery drain is negligible--At least until you use Navigation and forget to plug it in! Then you'll damn near be able to watch the battery icon visibly tick down, and might could cook an egg on the back of your phone, it gets pretty hot!
If you running ei22 stock, I can leave gps on all the time and don't need to worry about battery. But if you put in the gps fix, careful.

Screen Brightness
For 99% of users, the display is the #1 consumer of battery, which makes sense because you have a giant 4.65 inch 720p display that needs lots of power to run. The lower you set your brightness, the more battery you save. For a person like me, 50% brightness is usually the highest I use. Colors look clear, the screen is plenty bright to read, and yet it's not too high. If you want to save battery however, turn down the brightness to around 30%. If you're really in a pinch and need to save some juice, you can even turn it down all the way to 0%, but I would recommend keeping it around the 30-35% mark for general usage. In my experience, standard auto brightness doesn't work too well for me. It's slow to respond and either cranks the brightness way up or way down inappropriately. However, some ROMs like CM10 allow you to modify the backlight settings, which works quite well.
Maps/Latitude
This tip is a little more straightforward. If you use Google Now, you are using Maps location services which drain battery. It's always looking for your location to give you the latest weather, let you know about the cool sushi restaurant down the street, and other neat stuff. However, it needs to know where you are, so it's constantly polling the network for location data. So, shut off Google Now completely, or if you're like me and love it, just shut off the parts of it that you don't need, like Places and Traffic. I saved the big one for last. Latitude. The silent battery killer. If you're like me and you never use Latitude ever, guess what, it's probably still using your battery, so you need to shut it off. Simply open your Maps app, hit menu, then settings, then location settings, then disable location reporting and location history. Your battery drain should decrease significantly. I check this often because it seems to reenable on its own sometimes. Yikes.
Radios
WiFi is pretty fast at your house. Way better than 1 Bar of 3G. But when you leave, you leave the WiFi on, thinking it's no big deal. However, WiFi is one of the biggest battery killers, along with the other radios. So remember, just shut stuff off when you aren't using it. No navigation today? GPS goes off. Not using your headset? No bluetooth. Haven't invested in those fancy NFC tags? Shut that off, too. A big one is LTE. If you live in a 3G only area, what good is it to keep LTE on? It's just draining your battery. Turning Data off can save you money and battery. If you aren't one of the lucky ones still on an unlimited data plan, shutting data off will stop apps from using data in the background, and it'll also save a bunch of battery. However, you won't know when fnartsy123 liked your Instagram photo.
Apps
There are some apps that constantly use system resources and keep your device awake, even when you aren't using it. A major offender is Facebook. While a big update is rumored, the apps frankly sucks right now. It's slow and it drains your battery. Stick to the mobile website, as honestly, it works better now. That's the main one, but there are plenty of other. To identify them, I recommend an awesome app like Better Battery Stats or Appsucker from Google Play. They'll tell you what app is stealing your juice, and you know to remove it.
Auto Sync
One of the main reasons to own a smartphone is to stay connected, and I don't want to change that. I would recommend you shut off syncing for services and apps that you don't use. Check your Google account settings. You don't need or want all of your selfies to end up on Google+? Shut off instant upload. If you use Chrome instead of the AOSP browser, shut off sync for that. Go through and make sure you only are syncing what you actually use. Also, check your apps. Do you need to know when you have a new tweet? If so, leave it on. If not, shut it off. Furthermore, if your battery is in the red, shut off autosync altogether to save some serious juice.
Good tips, especially turning off google now, its useless and even worse its a huge battery hog.
Nice article mate. Very useful tips. Good job. :thumbup:

Great tips, but Id just like to make some additions:
Use Y5 to turn on/off wifi based on your location
Use Tasker to set a schedule to set auto-sync on for 2 minutes at 30 minute intervals.
nice guide, thanks
Just to let you know that you can keep the gps setting on. It only uses power if you are using the GPS. So yes if you have like google now checking for your location it will use power but if you don't have anything automatically using GPS then you can keep it on and it won't use battery.

Those screenshots are a bit old but it's still the same thing, I did manage to root it today, and I was testing Greenify which did nothing even with the Xposed modules, service disabler apps just did not show that specific service for some reason. I was able to remove the widget with Xposed GEL settings but it was still running even though the widget wasn't there.
So can someone please help me out here, maybe the search bar isn't the problem but I just want some battery life.

search and install betterbatterystats (read the whole first post) and it will tell you if its wakelocks etc.
Service disabler apps will need a setting to show system apps (or something similar) ticked or switched to etc.
greenify system apps in greenify also needs to be selected. You may also need to cut wake up paths to get it to stay greenified.
You could alternatively delete the apk of hibernate it (byfar the easiest option of all this).

Your 3rd image shows googlequicksearchbox had 370ms (milliseconds) of wakelocks over a 9hr period. I really doubt that is your issue.
If it is your top app, then it is probably because of Google Now launcher listening for OK Google spoken keyword.
I seriously doubt that is your battery drain problem as almost 90% of people probably have OK Google turned on and are using Google Now launcher and only a very few have serious battery drain.
BTW wakelocks aren't the issue usually. In the past it has been "partial wakelocks" which means an app locked the device from sleeping, but never released the lock, so the device never goes to full sleep. If you see some app with partial wakelocks or if you see some app with hours of regular wakelocks then that might be an issue. Minutes or microseconds of wakelocks are inconsequential.
I suggest you flash factory image and install your battery tester only. Turn off wifi, bluetooth, nfc, cell radio. Test the drain overnight. That is a baseline for the minimum drain your device can have. Then enable what wireless stuff you normally have turned on. See what that drain is. Then start installing apps and see what that drain is.
If you have reasonable/expected battery drain with stock and everything turned off, then it is just a process of elimination to see what is causing your battery drain.
If you can't get reasonable/expected battery drain with stock and everything turned off, then you probably have a bad battery.
For the record, my overnight battery drain with everything turned off is 0-1% With wifi turned on about 1-2%. With wifi+cell about 2-3%.
IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

What is your battery drain per hour with nothing installed and all wireless turned off and everything stock?
I'd only return it if that is significantly more than 0-.2% or 1% every 5 hours.
Otherwise it is something you have installed or something to do with the signal and how it interacts with your phone.
Once you start installing stuff or turning on wireless (wifi/bt/cell) then it is no longer purely about the battery and there are more factors that need to be isolated independently.
You really need to establish a baseline to see what the minimum battery drain is. Then you can determine if the battery is the problem or something else.
If you just install everything and turn everything on, there are too many moving parts.

Which battery life was the one you think you have a problem with, standby or in use? IMO for in use battery time this phone is about average. Your title of "wakelock" made it seem like you were concerned about standby battery time as it doesn't matter if there is a wakelock if the device is already turned on and in active use.
When turned on, the screen is probably the number one thing eating power, so adaptive brightness could help, but if you are in a bright area, it might be worse than if you fixed the brightness below max.
Even if you have adaptive brightness turned on, the slider scale still is useful as you give the adaptive brigthness mechanism some idea what level of brightness you feel comfortable when the mechanism detects dark, med, bright situations.
One of the worse things for eating power is for the cell radio to be turned on but have no signal, like inside office building or just a bad signal area in general. The reason is the cell radio is power efficient once it establishes signal, but when it is searching for (or loses) signal it uses a lot of power.
If you are doing a lot of disk activity like taking video or hdr pictures, it would probably help to have your userdata unencrypted as this device does software (kernel) encryption and doesn't use the fast/more power efficient co-processor.

Standby is the problem, on screen times are good enough.
Anyway, I don't even know what to do at this point. Android N didn't help enough (cell data is off), I guess I can flash Android 6.0 again and then try to fix it using apps...

Have you set "WiFi on during sleep" to "Never"? in the Advanced WiFi settings?
In the original release, there was a bug where WiFi would stay on even if you had set it to "Never" draining battery in standby.
Somewhere between MDA89E and MHC19Q they fixed it and WiFi will go to deep sleep after being in standby for a while, but they introduced another (or exposed existing) bug where WiFi will not resume after coming out of sleep, unless you cycle WiFi off/on. So you're standby battery should be better with this setting, but it'll be a little more annoying when turning on your device.
