When I run the latest android build on my Tilt 2, it flies through battery like no other.
Are there any settings I can tweak to get at least a full day's worth of use out of it (mostly in standby anyways)?
Thanks

I'd love to hear anyone's tips as well. As mentioned here:
http://forum.xda-developers.com/showpost.php?p=7959929&postcount=7622
Setting the sleep mode = 1 doesn't seem to work for me. The processor seemingly goes to sleep and enters a coma (yes, I set the clock speed back to stock in the startup.txt).
One quick tip to the OP is set the clock speed to stock.
Edit: sleep mode = 0 seems to work (GSM phone here). However, deleting the "acpuclock.oc_freq_khz=XXX" line from the startup.txt and setting sleep=1 just might work as well.
Edit2: sleep mode = 0 seems to result in the phone functionality breaking. It stopped waking up to phone calls after a while, and calling out wouldn't work either. Damn.. Just a heads up.
1. Close every program that you don't use on startup of android. You can do this with advanced task killer.
2. Run stock speeds.
3. Turn down the screen brightness.
4. Make sure your phone goes to sleep when you are not using it (green led = sleep)
Is advanced task killer installed by default?
Also, how can I clock it to stock? I wasn't aware that it was overclocked past stock.
Screen brightness makes sense, I'll definitely do that.
So, if green is sleep, what is the orange?
Thanks

I reckon hepatic feedback would drain a little battery on its own probably best to turn that off
This is all true. I'll have to do that.
Still figuring it all out. Once I can get a solid 18-24 hour charge cycle out of it, Android will become my primary OS, easily. Simply works better, IMO
For me sometimes it's green, sometimes it's Orange - not sure how to change it back green -
I use Advance Task Killer, but then i also read that Froyo 2.2 doesn't need a task killer?
The two things that have helped battery life the most were:
-Switching to stock clock speed (the reference over the overclocked BLZN which i loved but killed the battery life)
-turning off background processes... i only turn it on when i have to (using the market, etc)
I would love to hear more tips
The colours are not that hard.
Red/orange = awake
Green = sleeping
If the LED stays red, then your device is doing something, you can either wait or try closing the programs with the task killer. That will help sometimes.
For returning to stock speeds read the faq And advanced task killer can be downloaded in the market.
Thank you guys all so much, big, big help to me!
Android is definitely going to be my full time OS shortly

Its kind of tough trying to go anywhere without a charger nearby. The battery drains quickly and on top of that the actual battery meter is off.
So sometimes that is a main issue

Indeed but that is something that they are working on it as we speak. Give them time
I ran a test last night before going to sleep to see how long the phone lasts.
Charged my phone fully. Ran advanced task killer and killed all the programs. Put the phone in deep sleep ( green light).
Woke up 7 hours later and phone was completely dead. I do have auto sync turned on, but only over wifi, so it should not have used any data as i have the data turned off and no widgets on my home screens that auto-update.
I'll try again tonight for a shorter time (5 hours).
Running the blazn aug 30th build.

How did you 'put the phone in a deep sleep'
I turned off all auto updates.
The next day i did the test again, charged the phone to 100% and used the phone moderately for 8 hours before the battery died.
Without overclocking i can safely say i can get the phone to last 8 hours with moderate to heavy usage, which is excellent.
My main problem with the new updates are that it constantly restarts or crashes after using it for less than 30 minutes while before I could use it for several hours. Not sure whether it's to do with battery life or not as when it boots back in WM the battery is near full.
The biggest things that have helped conserve battery life for me are disabling GPS and background syncing but some apps require this to be enabled. :S
Phone seems to recover from "sleep"
FWIW, I set sleep mode = 1 and removed the overclock line from the startup.txt and the phone SEEMS to sleep and "wake up" just fine. Previously, I had problems with the phone going to sleep and when waking up, everything seemed fine, but the phone didn't work. With the overclock line removed, it seems to "wake up" with the phone working now.
Just a heads up to anyone who wants to save battery life.. might want to remove the overclocking line in the startup.txt..
my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week
With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)
What do you have now? Stock or rooted?

First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!
be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it
Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.
i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge
I calibrated the battery and that made no difference.

So several people have started to notice that "AudioOut_1" wake lock might be polling our batteries unwillingly on our part. So I decided to go out and disable everything that could make sound except for the ringtones and notifications themselves since we all have to have that. This is what I came across...
---------------------------------------------------------------------------
Settings > Sound
Uncheck "Touch sounds"
Uncheck "Screen lock sound"
Profit.

Just went an hour without losing 1% battery after I did this.
Some people are claiming they only are losing 1% or less per hour now, just leaving the phone sitting not doing anything. So this may be the temporary fix for the phone being awake when it doesn't need to be.

Seems to be 50/50 on this
Ive had those off and I am actually going to run my phone in vibrate only mode for a while and see what results from that.
this has little to no effect on battery life. Look at your Android OS battery consumption before, and after. It will be the same
Biggest solution I've found for battery life is disabling my GPS when I don't need it, and going to CDMA rather than LTE/CDMA. They're still there for me when I want them, but most of the time I don't need them.
Right now I've had the phone off the charger for 4 hours where it was topped off; I'm at 91% now, with moderate use (Google Currents for half an hour, about another 20 minutes total screen-on time doing other dinky things, three texts)
First of all, disabling GPS will have absolutely no affect on your battery life. The GPS is only enabled when an app calls for it, if you don't have Google Maps open, then your GPS won't be engaged.
And turning off the sounds will have little to no affect, it's the vibrating that kills your battery more. Turn off haptic feedback, turn off vibrating notifications, turn off vibrate on key press for the keyboard.
Oh, and staying connected to wifi is much easier on the battery than using data. On wifi your phone doesn't have to keep polling the cell towers for signal

Turning off GPS works for me because I often use social apps (e.g. Facebook) that engage GPS for their 'check-in' features. It may be a minor thing, but having turned the GPS off, I've seen real results. *shrug*
Also, maybe a gimme for you smarties, but I disabled VZ Backup Assistant.

Yes what you are saying has made sense in the past for Froyo and GB but we are having some sort of unknown wake lock and this seems to be the biggest one. Ever since I have disabled both of those features my AudioOut_1 wake lock hasn't awakened the phone ONE TIME.

I had a custom rom with dreadful battery switched back to the latest stock and have noticed the following: When you have good signal the screen on and awake seem to match up, i only lost 30% in TWO DAYS! then suddenly when i went out to the country side today i lost the remaining 70% in only a few hours seems that when the phone has low signal is is almost ALWAYS awake. I understand that in lower signal areas the phone tries harder to get signal but surly it shouldn't be awake like 90% of the time!
my top 1 was some sort of googlephotos sync service. i might turn off instant upload with google+.
that audioOut_1 was at like 1.2%, turned off these 2 settings before i unplugged from charger

Yep that is another major contributing factor to terrible battery life. My phone will drain VERY slowly in good signal and die rapidly in bad signal.
I charged my Nexus LTE(unrooted,4 days old) till it was 100% before I went to bed. As soon as I set my alarm I unplugged it to test to idle. Well I just woke up 6 hours later and it was completly dead. I have it on the charger now, I hope i can see the spycpu cause that was main purpose for leaving it off. I do not sleep surf either.
Is this a defective phone?
Wow that's nuts. I definitely never get that sort of battery drain. Are you rooted? Using a custom rom or just stock?

Are you sure it was dead or you just had a sleep of death? If it truly was dead you definitely have something draining your battery during idle. I highly recommend you turn off your LTE antenna if you haven't already unless your using data intensive apps and you need it, such as surfing or netflix or something. Also, change your sync times to less often, I do every 15min. Sign out of google talk, use wifi when you can, adjust screen brightness, disable bluetooth. White backgrounds will eat your battery faster as well. What else am i forgetting.... Root will help if you can manage to, its incredibly easy especially with the new rootkit out, because you can load francos newest build which has increased my battery 2x, with 25% drain in the last 8.5 hours even with a 1/2 hr of whale tail last night. Also make sure your not running something stupid in your background thats eating your battery like a task killer or battery spy or something, those just rape your battery
If you turn on Google+ instant upload and it has thousands of pictures to upload that will kill your battery in a few hours. If your phone is staying awake because of Android OS then try turning off your GPS.

As noted in a lot threads on a lot of forums, there are some phones that have a problem with the Android OS and the "Keep Awake" time. There seems to be an issue with some phones not truly going to sleep when the power button is used to turn off the screen as opposed to letting the screen turn off automatically when the screen times out. This results in a very high time in the Settings/Battery/Android OS/Keep Awake menu.
In stock form and with every rom that I have installed, my "Keep Awake" time was always about 50-60% of my total battery time. If the phone had been off charger for 8 hours, I'd have 4-6 hours of Andorid OS "Keep Awake" time. This was true even if the phone had been in my pocket unused and seems to be exacerbated by my habit of turning the screen off manually with the power button every single time. I used to never let the screen timeout.
There seems to be two "fixes" according to Franco (of kernel fame). One concerns the camera. Seems the camera is started and then turned off during startup. But in so doing, it leaves a sensor active and this prevents the phone from actually going to sleep. So he recommends starting and using the back button to go back to the home screen. The other is DRM Protected Content. He recommends this be disabled or frozen. A third, that I don't believe I recall seeing him recommend but that I have seen on his thread at XDA (down for blackout right now) is to disable Maps.
I have done all three of those and my Keep Awake time has gone from 40-50% of my total battery time down to a few percentage points. I mean if I don't use my phone it will now show less than a minute of Keep Awake time per hour.
Good luck
My VZW nexus can idle with moderate use on constant LTE and get 15 hours with out issue. Hell I have even gotten more so check google+ as suggested. If it went dead on idle with nothing running constantly to cause it than I would say your phone and/or battery is defective

Ive been getting good battery life, despite my awake time being around 6-8 hours at the end of a charge. I tried the camera close but that never helped, I've just disabled DRM though. Also, GPS locator has been associated with this, which is probably what you meant by "maps". I just turn off my location unless i need it for navigation in location settings

It has to do with digitally protected files, music, etc. One time I went home screen/menu/settings/apps/all/drm/disable. The last time I did it from Titanium and pressed the freeze button for that app.

Hi, how its your average batery life?
I have never really run any tests for it, but i've left the tablet alone for a few days, just sometimes checking for Firmware updates, and it barely lost 30% (maybe less, can't recall).
with no live wallpapers on mine lasts a few days with moderate use (checking email, rss, news, maybe playing a couple games)
Well i got the Archos 80 G9 250 gb version and mine lasted for 4.5 hours of continuous video playing , screen brightness on 50 % . The problem is that even in deep sleep it looses battery . How can it last for a couple of days i can't understand , any hint ?
I have the flash version, maybe that would make a difference. Check the wifi sleep policy, and make sure it turns off during sleep. Also, I keep bluetooth and gps off. perhaps try that?
I have the basic 80 g9 and for just using it the evenings it will be happy to last for 4/5 days with email, twitter simple games etc. When I've travelled with it in 3 hours of video playback I lose about 50% with no connections such as WiFi or 3g.

Well actually i didn't checked that but i have the impression that mine looses a lot of battery in suspend mode .... I always shut it down and even like this when i start it again its not the same as it was .... maybe the actual starting process uses a lot of power don't know
Could be a rogue app. My phone was like that for ages and it was getjar nit letting the phone sleep properly. Try better battery stats or something similar to see if a service is causing partial or kernel weaklocks too frequently

The 80G9 1.5 GHz turbo I just started using is to new for me to get an idea of run time, so far about 8 hours of mixed use, on my 8gb classic would go between 5.5 to 9 hours depending on use, in deep sleep non use, it would go for days at least
What works for me, on best battery management, I like to put into deep sleep every time I put tablet down and plan not to use for a few minutes or more (this turns of Wi-Fi, screen, and stops mosts things from running) it always wakes up with a quick power press and Wi-Fi connects within a few seconds
I use normal sleep (same as when it times out I think) for quick pauses in use.
normal sleep for when not using but charging if I want to hear notifications for email, Color Note, Evernote etc. (Wi-Fi on)
If I want the quickest charge, (not using, overnight etc.) and I don't care about notifications (Wi-Fi off) I use deep sleep. edit, to be clear on notifications, my Color Note notifications work while in deep sleep
Turn off for longer periods not being charged/ used
You can set when Wi-Fi disconnects by going to:
settings, Wi-Fi, Wi-Fi disconnect policy (I have mine on never for now)
*and of course, use the correct cable and charger!
