another battery thread? please help!

Ok I've had my desire now for couple if weeks. I've read many many posts regarding battery issues so please bear with me.
I've come from iPhone 3gs and estimate my battery is seeing 25 percent less capability.
There are it appears many settings for internet connection. (Always enabled, auto sync, background sync, connect to internet, then individual settings for certain apps when they wanna sync. And then WiFi settings. What I'm after is to kill the internet completely when my phone is not in use, (this is regretable but have to save battery).
What I want is to kill the internet completely when the phone is not in use. No background, no sending hunting for signal etc. Then in one click I wanna connect. AND have the apps sync that I want synced. And have full internet etc. Then in ONE click shut internet off compleley. Is the best way to do this, by setting up your auto sync and background to be always on. Background always on, everything always on or connected, then hold the power button to wake the phone but hold it till you get menu and then select connect to internet from one of the options. Then when I pit the phone down, hold power key, then select disconnect from internet. Will this work and kill my internet connection 100 percent? And get everything synchronized when I turn it on?
Not interested in juice defender, read some bad stories (aswell as good)
Thanks.

Long press the power button, click 'Mobile network' to toggle it on or off.
I use this settings when in work as I have a very poor 3G/H signal in my office, other wise the 3G/H singal drops and connects like a yo-yo all day long draining my battery like crazy! I turn it back on when I'm leaving work. This way I still get calls/texts while in work and I'm sitting at my computer for my internet.

JuiceDefender (even the free version) is working wonders for my battery life. The basic version forces your mobile Internet connectivity to only turn on for 1 minute for every 15...amazing what difference this makes.
I've been using it for the last three days or so in basic mode, and my multiplier is already over x2.
The only downsides I've found are that the 3G/HSDPA is a little slow at "waking up" if I want to use it if JuiceDefender has previously turned it off...I have to have the screen turned on for about 20 secs before a connection initiates - it's a relatively small price to pay, however.
As a rule, I have auto-syncing turned off during office hours since I'm in front of my PC at these times, so don't need to have GMail, NewsRob, Weather, Facebook, Twitter etc. updating on the phone. I turn syncing back on just before I leave the office - and there is plenty of stuff then synced up ready for me to look at whilst on the train home. I leave syncing on for the rest of the night whilst I have WiFi on the phone - and this seems to draw *far* less battery than when 3G/HSDPA is constantly on.
With this routine, I'm easily getting 24 hours out of the phone now...
The real battery killer is when you're using Internet-enabled services in a patchy area. The battery drains away extremely rapidly I've found. In can easily lose up to 40% whilst on the train home (which takes no more than 1hr 20mins) whilst I'm trying to use the Internet etc. as it is constantly cycling between cells moving between G-3G-HSDPA...

I'll agree with everything rodhull says, especially the lag after switching the screen on. But I know the developer is working hard to resolve this and other issues. JD looks like it will very shortly be an excellent solution to this, which is really an HTC problem - they should have provided a better battery!

I got my Desire a week ago and the first two days it drained in no time.
Today i have used the phone for playing, surfing, talking, mail, used wifi and gps . and I still have 48% left on the Battery.
Time since last charge is 16 hours and 4 minutes.
I am not doing anything special to preserve the battery

Me too, when at home my battery uses about 1-2% per hour with everything syncing and stuff. When at work, it's 6-8% per hour and it's switching between 3G and 2g the entire day. This seems to have a very big influence on battery life.

Hi All.. Just visiting from the X10 pages.. we're having similar battery issues over there too... suspect that these "super smartphones" are really battery killers... A lot of people on the X10 seem to be getting much better battery life now - I got c.40 hours out of mine earlier this week - with wifi usage - no BT and no GPS... There seems to be a few useful things you can try.. first of all - most people have now ditched Juice Defender.. concluding that it doesn't actually help at all.. if anything I reckon it was using more juice..
Wifi sleep policy - set one.. !
Switch data services off when you don't need them (when asleep etc).
Specifying just 2G/ GPRS when in a weak 3G area..
install task manager or ATK to kill apps that run in the background.. sucking up juice!
Hope this helps some!

Battery Life

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...

[Battery] Excellent Solution for high battery drain

Hi to all
After many fights with my loved Desire i'd found an excellent solution for the high battery drain.
I have the OxygeN ROM 2.3.2 (very very very nice and stable ROM) but the average life of a charge was 1 day.
Searching on the market i'd found the app "Green Power" (free version). This app allows to manage the WiFi and/or 3G connections when the smartphone is in stand-by (SLCD turned off). Setting the parameters it is possible to swith-off (i.e. every 30 minutes) the WiFi and/or the 3G. This make a big decrease of energy consuption. So my average life of the battery between two charges is 2-2.5 days .
Very very very excellet solution
Hope to help anyone
BR

If you just want to do wifi its already build into the roms. You just need to go too wifi settings and hit the menu button and select advanced settings then play with "Wifi Sleep Policy" I have mine set to "Never when plugged in"

I read before that the WiFi radio actually uses less power than the mobile data connection, so leaving WiFi on and Data Off would drain less battery. Although obviously both off will increase it, which is how JuiceDefender works as well. But i find if you can live with all data off for periods of time you probably don;t need a smartphone in the first place, the whole point of them it to be always online for push notifications and the like.

not 100% true
with my actual configuration (30 minutes OFF and 2 minutes ON) i receive all emails and notification of the day. obviously not instantly

Seeing equal or better battery life on wifi vs bluetooth

There were lots of comments (and still are) about how wifi is a battery killer on android wear. I'm not seeing this to be the case at all, when it's working like it's supposed to.
Since 5.1.1 my battery use has been around 3% and hour with all features on. Turning off bluetooth on my phone, with a 2/3 wifi signal on the watch, I'm seeing 2.5 to 3%.
Quick drain happens when walking around the edge of bluetooth range, as the watch switches back and forth between bluetooth and wifi. It seems that as long as it's not finding bluetooth, battery use is normal at worst for me.
I know that the moto 360 will switch to a state of only checking for updates occasionally to save battery, but I don't see this happening. Notifications are coming to the phone, and shortly afterward on the watch. I have not seen a time when a notification was delayed more than a few seconds.
The downside to wifi-only use: some apps that communicate with a phone app don't work. My watchmaker face doesn't update the phone battery level. Google voice commands fail too often, maybe half of the time.
I think google should change the frequency of attempting to reestablish bluetooth connection while on wifi.
Has anyone else tried this? Either turn off your phone's bluetooth, or make sure it is well out of range.

I'll give it a go tomorrow at the office and report back.

Thanks to a heads up by DarkRazorZ, I learned wifi can be turned on in airplane mode. Will be looking to see if this makes any more difference.

Watch maker has been my biggest battery drain. It also makes the drop down menu laggy and impossible to use.

Yeah, I had that problem with watchmaker. I use intelligent and it seems to work well. Other people report facet works too.

I concur. Wi-Fi uses a lot less battery than Bluetooth, with an acceptable lag - 1-2 seconds on notifications. Bluetooth seems like a big battery drain on the phone and on the watch.

Keep wifi on past time out limit

I use the watch to continuesly read the Libre blood glucose meter via nfc, so I have the LCA43 kernel with nfc enabled (watch rooted).
In the wifi menu there is a time out setting how long to let wifi operate. The longest possible time in the menu is 180 minutes.
Is there any way to remove this battery saving "feature" or set a longer time limit?
And while working on the question above, any idea how to interpret the limit? I couldn't find any specific info on the Sony site. (maybe total 180 minutes wifi usage between charges, or upto 180 min continues wifi usage that restarts when a BT connection is established and later lost again)
Thanks
