is there any way it can help my tilt from preventing battery drained..it was fulled charged at 11 pm (only instant message was still running but no messages), woke up at 9am and theres only 53% battery left. i barely listening to music but when i do it killed faster.
changing radio can change the rate of battery drain
What type of Messaging were you running? What program? Some keep a continual data connection & if you're in 3G territory that can easily account for that battery drain.
I used to leave HSDPA on and auto check email every 10 mins, my battery only last more than a day even without any phone call in this time. I was then disabled the 3G + HSDPA, just leave the GSM on (changed this in the phone's band), my battery now last about 4 days and still have some power.
Your data connection kills your battery severely, this may be what caused your battery drain 50% over night.
my 3G is always on. I have internet and everything. does 3G interfering my internet connection?
u can get very good battery life when 3G service is deactivated.
also make sure disable wifi, make sure when not in use no application will auto on the wifi...
make sure device lock is set to lock all buttons.

what does HSDPA do? i turned off 3G already. i pay unlimited monthly internet so are those things that i turned off interfering anything from it? i Disable HSDPA already and my internet still connecting. sorry for many questions but im pretty new at this tilt.
Just make sure the icon and or mobile operator name has no 3G indication. Yes u still can get connected via internet, which is through your GPRS, which online activates when as you wish. 3G is passive mode whereas GPRS is dynamic.

so im running dutty no. 3 final rom with directpush enabled as items arrive.. now im constantly in H and my battery only lasts 2.5hrs in H mode.. compared to the hermes this is HORRIBLE! any one have any ideas? i know H means highspeed pda.. so im wondering if thats why.. i kno the hermes switched back between 3g/H..H only when downloading but the tilt seems to be H non-stop.. whats going on?
I am still on the stock rom and mine lasts 20-24 hours on average.
Well, you answered your own question. You're using DirectPush, which forces a constant data connection. You're using HSDPA, which is a notorious power hog when transferring data, and you're now using it constantly.
If DirectPush is that important to you (i.e., if you get mail so often that you might as well be in constant communication with the e-mail server, or if the mail is so important that you have to have it now), you'll need to find a way to switch off HSDPA in favor of EDGE or GPRS.
There's really no other option.
i like to feel important thats why i use direct push.. the job doesnt require it.. but they do require to check at least once a hour during normal business hours lol. i suppose to could set it to check every hr... shucks. why would it last all day on my hermes but under 3hrs on my tilt?
I've never got more than 35 hours battery life, with gprs (UMTS disabled), pushemail, and 1-2 hours of music playback...
The battery life is VERY BAD, my wizard's time was about 50-60 hours with same use...

I installed Duttys Comm Mgr with a 3g on off switch and when I am not surfing the web I am on edge. It has helped dramatically with my battery life. My job requires "as items arrive" Direct Push. I can go a whole day without charging on Edge.
3G was recently enabled in my area and I do not get more than 7hrs of batt life with DirectPush active. Before with EDGE I was good for the whole day (>12hrs).
HSDPA is the problem not DirectPush.

can you give a little more detail on your settings with 3g off hdspa off bluetooth on and moderate usage of wifi (less than 20mins a day) and only about 30min of calls i only get between 14-16 hours, any info on how to get the extra battery life would be apreciated
I have 3G, direct push, bluetooth on all day and my Tilt outlasts my TyTN by about 30%. I generally charge every other day with normal use.
well....post ur rom maybe? are u in 3G or H all the time? im constantly in H and havent seen the 3G icon at all..

When did AT&T enable HSDPA in your area? It's relatively recent to many metro areas, so it's entirely possible that the Hermes was on Edge 24x7 and what you're seeing is the additional drain of HSDPA and not the change in platform.
But if you're only getting 2.5 hours, there's something else going on. You've an app that's keeping it from going to sleep, you get e-mails every 5 minutes or so, or your battery is bad to begin with.

Sleuth your running your own cooked ROM for your Tilt aren't you? I loved your ROMS when I had my Hermes.

people seem to forget that the mechanism for mobile data is the same as for voice - when you are talking, the phone is just digitising your voice and sending it over the wireless link. Nobody seriously expects 18 hour talk time out of a pocket sized phone, so why do we seem to expect 18 hours of heavy duty data on-line time.
Ok - I know that is a bit simplistic - when you are talking, the data transfer is continuous whereas for ordinary web browsing etc. it is short bursts - but if you are running something which is holding your data link active a lot of the time, you are incurring a similar battery drain to talking - the Kaiser is rated for just over three hours talk time - don't expect 18 hours of push email! And don't forget that the battery drain is simply for running the transmitter in your phone, not for sending the data - sending one byte will consume as much battery as sending a hundred or more - once it decides to send a packet, it is committed to burning charge even if the packet only has one byte in it...

Just an observation...
I live in the DFW area and my battery life is not up to par with the 8525. I traveled yesterday to a EDGE only area and I noticed a dramatic increase in battery life. Are they related? I dunno at this point, just an interesting observation.

That is for sure your issue. The data connection is not only live, but is being used constantly. Turn off direct push and see if it reverts back to 3G. If so, make sure you are not set to use MediaNet as your primary network. Also, be sure to uninstall the hidden proxy (look for the cab that does this in the Cabs thread).
With direct push enabled, my 3G icon only changes to an H when mail is actually coming in.
On my Nokia N95, constant HSDPA connection too chews through the battery as opposed to "plain" 3G; that is, the Kaiser isn't an exception either... It's the best to fall back to GPRS (EDGE) whenever possible.

well on my hermes i had 3G ever since i got it.. but it only went to H when downloading.. so ive had my tilt for 2-3 days now and its always in H.. i know H causes more drain then 3G standby and by far G/E ..funny this is.. i disabled htc home and battery isnt to bad... bout 3% drain every 3mins when connected to H and idle internet connection.

ive turned off direct push and it still remains H.. ill try disabling the proxy. good call.. will post my results
ok disabled the proxy, turned off push, still have a big H but no more tiny H on the signal bars which means its not connected to the internet but when i soft reset it automatically reconnects.. whats the deal here lol.
ok forgot i had kaiser tweak set to always on.. fixed that, but now im still displaying H havent seen a 3G icon yet.. whats going on lol
hi,
i was wondering if there is an app which will automatically switch from 3G to 2G when i turn of the display. When the phone is in my pocket there is no need for the 3G eating my battery.
that would be an amzing app BUMP BUM BUMP
It indeed would be. I'm on it.
EDIT: Then again, switching from 3G to EDGE and vice-versa is resource/battery heavy in heavy and will probably leave you without network for a while. I'm actually going to say it's not worth it. If I create it, I'll post an initial version up here for you guys to decide (no 3G frequencies for me).
Edit: it seems as though there's nothing in the api about switching network state. Looks like a root app (if it's even possible) would be required..
Edit2: This is probably impractical. For example, if you answered a call, you would be disconnected from the call immediately. Besides, the G1 is rated as having more sleep battery life under 3G than GSM.
How does being on 3g even waste battery when your on idle? what Syncing with gmail? i would think the constant switching would waste more battery
I guess you could do it with Tasker. I got that app in ADC2 and it's amazing what you can do with it.
I guess it would be very impractical if you would get disconnected everytime you answer a call from a sleep state. I havent compared the battery consumtion between 3G and "g yet, but i imagine you could save quite some. m not only talking about the Synching, but mainly Chat clients which run in the background. There is no need for them to run over 3G.
I have a ATT type Nexus One (not Tmobile), unrooted, with latest froyo.
The life of the battery in 3G mode vs. 2 G mode is astonishing...pretty ridiculous.
I'm searching but can someone tell me if there's been any fixes or advancements in regard to this problem?
When at home I use wifi as much as possible. I leave it on 2G but really, I can't take the slow speeds of 2G, but 3G setting is suuuuuuch a drain on the battery that it seems unreal.
i've had nokia's and more in 3G, my wifes iphone is 3G... and all of them had nearly more than double the battery life.
I hate the voice quality of 2G, I'd love to be able to just leave at 3G, but it's merely hours before it's nearly drained set on 3G. it's got to be a problem (and one that hopefully can be fixed).
Why would 3G setting be sucking THAT much power (decent-strong signals too here)?
Love my nexus1 and I'll live I guess but this problem...it's a bit much.
Any news on this issue, or other things I can consider or change/try to help this? (3G)
thanks
Set your WiFi sleep policy to NEVER. Even thought you're using WiFi at home, whe nthe screen goes off the WiFi shut off and 3G kick in.
Menu>Settings>WiFi settings>Menu>Advance>WiFi sleep policy>Never.

Oh very sorry, I should have said I did set this to never and saved changes.
In fact, I think I've set it 1000x now btw, over some time it STILL always disconnects from wifi (might be router disconnecting though, perhaps I should set an IP manually to solve this??).
GPS and BT are always turned off until needed as well (used very rarely anyways btw).
But when I'm away from home for example, I turn wifi off and test the difference2G vs. 3G and the difference is waaaaay too much, 3G just CHEWS at the battery no matter strong signal or medium.
I find it hard to believe 3G really has to eat up that much battery when set compared to 2G on a Nexus. A little bit to nominal ...sure, but not like this (say like 4-6 hours if i left it 3G for a day with little usage).
What's really happening here? Nothing from google/HTC on this matter?
Heh, i get just the opposite... out in the farmland of west toledo, im getting 2G but typically GPRS and that rapes my battery where as 3G i could go on standby for days if i didnt touch it...
What radio are you running? if your phone is constantly looking for a signal then that may be your problem...
I have the same issue on 3g. Home on WiFi is ok but when I go out during the day on 3g it just kills my battery.
The reason is because android OS keeps the data session open at all times where other OS's close it down when not in use. It's just the nature of how they designed android.
As a test, one day turn off your data connection but stay on 3g and see how good your battery life is. This is how some other OS's work normally.
It's a trade off we have to make for being always connected on android.
For example voice actions need to reach out to Google's servers to work. So in the interest of speed of having to open the data session each time, the OS just keeps data open on hand at all times. But that kills battery quicker.
That's what I've found anyway.

That's because the phone is always on the lookout for a 3G signal, if you know you aren't going to get one, just set it to 2G only and your battery life will massively improve.
Hello fellow XDA's,
I've found a way to save the battery in CM7 in a huge way. You must have CM7 for this (maybe Miui will work also, but I can't guarantee that). This enables the 2G Only setting automatically when the phone is asleep to save battery and when you wake up the phone, it will automatically (or manually, you can choose this) turn back to 3G.
1. Go to: http://forum.xda-developers.com/showthread.php?t=739530
2. Download: Toggle2G-Update.zip
3. Install Toggle2G-Update.zip through recovery
4. Open the app and turn on the following options:
- Auto Manage 2G/3G
- Manually Activate 3G
- Activate with Notification
- 2G when sleep
- Sleep delay, set to 2 minutes
- 2G when low battery
- Battery Level: set to 20% (you can choose the % level yourself)
- 2G when wifi enabled
- 2G Network, set to GSM Only
- 3G Network, set to WCDMA preferred
- I choose manually activate 3G, because sometimes I Just want to check notifications or the time and I don't want my phone to switch to 3G every time I wake it. I think that will eat battery life.
- I choose Activate with Notification because I want to be able to switch to 3G "on the fly" (without going through the settings) when I need 3G.
- I choose 2G when wifi enabled because it is useless to have a 3G connection (for your calls/text) when wifi is enabled, 2G is good enough for that.
These are the settings I've made for my O2X and it looks like it is working wonders. After 18h, 6m, 36s my battery level is 42%. So I guess I could make it to around 34-35h till the battery dies. I've made a few calls (about 15-20 min), about 20-30 text/whatsapp, checked Sygic a few times (to see if GPS was getting a fix), some browsing (5-10) min and updated a few apps from the market. (browsing and updatings apps was with wifi enabled, about 10-15 minutes)
I'm using CM Nighlty#101 with BB/Ril 0725.
Testing it out right now. Seems like an alternative to Juice Defender.
When i am in 2G, data is off as well?Mine seems off.
sorry but can't use this trick.. My operator is 3, so 3G is the standard network. When selecting 2G, no network is found (--> no service)

For me data is on with 2g. For example: whatsapp messages (which needs data connection) are coming through

They used to fall back on Orange 2G, until they decided to shaft us customers in poor signal areas & save some money by canceling the network sharing. So I took my money elsewhere.
Great find! I installed this and everything went smoothly. I then went through and applied the settings exactly as you recommended. Only problem is, nothing happens. Zip, zelch, nada. I've left the phone laying for 30 minutes, picked it up and discovered it never even went to 2g at any time. This is just an idea, but perhaps my 2G and 3G network settings at the bottom are off. I'm in the U.S. with a Droid 1. Any ideas?
is it working for all cm7 nightly?
this is great, thanks!
Wi-fi (always on) + 3g drains 1% per hour for me. Under 2% per hour with 3g and data controlled by JuiceDefender, no wi-fi. Not sure what more you could want for idle power drain.
I'm coming from a Note 2 and I'm somewhat confused as to how this phone handles everything network related. On the note 2 whenever I would connect to wifi, my LTE symbol would disappear and show only a wifi signal, and I THINK the mobile data was switched off until the wifi connection dropped (I'm probably wrong). I also wasn't as concerned about battery drain with that phone since I had a 7600 mAh battery.
On this phone, regardless of if I'm connected to wifi or not, the cell data (empty "bars") logo always shows at the top. Now normally this wouldn't really bother me, except "cellular data" is using nearly 5x the battery that wifi is using. Are phone calls/SMS also tied to the same data stream/radio as the LTE? I'm on wifi for around 80% of the day. I didn't know if disabling cellular data would stop me from getting phone calls/sms. Again, I'm not sure with the note 2 if that was just a touchwiz feature or not, but I was wondering if there was some way to automatically disable LTE radio (if it isn't tied into calls) when I connect to wifi. Cell standby is my number one battery drain after the screen.
Cellular data is off when on WiFi. The only time you'd see it on is when a MMS is coming through.
Cell standby is just your radio connected to the tower.
