I have a friend that sent me this message today, which sounds like a great idea:
I've been messing with setcpu and trying out some underclocking profiles. Underclocking while the screen is off as well as reducing the CPU power has gotten me 75% battery left after 8 hours. This is with constant emails but no wireless, bluetooth, or gps. This is better than I was getting under windows mobile.
Using a complete black background as your desktop background screen also helps with battery life. The black areas dont use battery power.
If you install one of the cpu meters, it will show that there is automatic underclocking... mine says it has been running at 100MHz for 76% of the time (1 day uptime).
Android System Info will tell you this.
Now, I'm not sure if this is the same as what you are doing though.
You know, I believe that is correct. I don't know if he is getting any advantage or not. I'll forward the info to him and see what he thinks.

That only helps if you spend a significant amount of time on your phone's home screen or hit buttons a lot when the phone is in your pocket.
I've found that the best way to save battery life is to use manual brightness. Auto brightness is just too bright. In fact some newer firmware hidden on samsung's site does make auto brightness a bit dimmer.
Using manual brightness I get about one hour and fifteen minutes of screen time per 10% of battery. I get about an hour per ten percent at work, where it's brighter. I get about half that with auto-brightness.
I think one good way to test which i am going to do to tonight is charge your phone and right before you go to bed unplug it and let it run through the night and in the morning see what sucks the most battery. i'm going to assume it should be "phone idle" but if its cell standby then something is sucking data, someone correct me if im wrong .
Just flash to jh2 out jh3. I'm on 16 hours and have 50% left

I know my 8525 (a precursor to the tilt) had excellent reception. It was far better than average. This captivate is not as good. In my experience the captivate has average reception. I've had much worse.
Well, my buddy that told me about the topic I used to start this thread just stopped by.
He is playing with an Android 2.2 ROM that has been installed on his HTC HD2, which also is undervolted a bit. And of course, tweaking with SETCPU>
He said he is getting email and messages etc as normal; has full CPU and good power when using it (BTW...the Quadrant readings on his phone is coming in at over 1700). His phone has been up for 24 hours, 15 minutes when he stopped in, and he had 58% battery left. Before he started tweaking (and I think before the undervolted ROM), he was getting 11-12 hours on a charge.
Sounds pretty good to me.
Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you
I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.
Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..
I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...
Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.
I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.
Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours
neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.
Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?
Sent from my HTC Glacier using XDA App
simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.
So after 2 hours and 3 minutes...my battery is at 25% ...since starting to write this message it has dropped 3%. The display is taking up 80% of use. Screen brightness is about a centimeter from the far left side. Screen has been on about 90% of the time...however...after only 2 hours and now at 23%...I'm a little concerned. Any suggestions?

I does pull less power but having it on all the time while at work will still drain your battery pretty quickly and why want you have this on all the time?

It was more of a test to see how long it lasts with the screen on. I am a little concerned though because lets say I'm sitting in an airport or on a plane watching a movie(I travel for business). My old Droid X could get me through that. But I'm thinking that it wouldn't be an option if my battery is dieing after 2 1/2 hours with the screen on.
Coming from the droid x, kernels weren't an option so I don't know much about them. Would an enhanced kernel be able to help with this drain or am I SOL?
I'm having battery issues as well and hoping someone can help. I heard people are getting great battery life with this device, but so far mine is about the same as the thunderbolt was. My charge says its mostly the display taking up the battery life, but I've done all I can to help this. My screen time out is at 15 seconds and my brightness is at about 20%. I am running ADW EX but I wouldn't think that would cause this. Anyone have any other ideas?

The screen does use less power, but a significant amount of the power savings comes from displaying black, as black uses no power on the display, where it does for LCD displays. For me, the Display is usually responsible for 65-80% of the power drain, so your usage seems somewhat normal. Custom kernels can help with drain some, but what can be tweaked with a kernel won't help with the display draining the battery.

Potential Solutions?
So besides reducing screen timeout to minimum, turning off background data, and cutting off literally every single connection (wifi, BT, 3g/4g, gps, everything) except 1x for calls and texts, removing bloat, are there ANY other measures one could take to enhance the stock battery life? I find myself talking on the phone for roughly 1hr per day but I do send nearly 500 text messages daily thus my screen is on a good portion of the time. I have to charge this phone twice per day at 2.5hrs per charge, it sits near an outlet for 5 hours a day heh... In fact even though I live in a 4g area I can't really use that feature because it beast's the battery down like a ravenous monster even with ALL other services disabled, not making calls, just texting and syncing email.
Task killers:
To me the task killing programs (ATK, ATM, etc) do actually kill background tasks and sometimes even services depending on your particular settings but since they just restart automatically does it not use MORE cpu time to re-run the damn things than just leaving them in the first place?
Launchers:
I have found no significant difference whatsoever between battery life under TouchWiz and LauncherPro. If anything its worse with LP because of the nifty graphical effects.
Kernels:
I'm pretty sure I read somewhere people were experiencing better life with the v4 voodoo kernel however I've noticed no difference at all there either with regard to battery life.
Running the phone with no services and charging it twice daily seems fairly extreme, eh? The extended battery is tempting, but one thing that attracted me to this device was its slim design. I don't care if its a little thicker and all but that ext battery is a freaking monster! Forget having a case with it too, at least for now.
Thoughts, suggestions?

500 text/day? Wow, you must be under 20 with thumbs/pointing fingers of steel! If your average text message takes 30 seconds, your screen is on and the screen/keyscan interrupts are running full bore about 4.5 hours a day just texting...when do you have time for Angry Birds?
Maybe a thin white text on black background for your screen theme? Just kidding (sort of), but I'm amazed at the talk/text times; gettin old, I guess!

Seems like this explains while some report great battery and others terrible times...depends on what somebody considers "normal" to "light" usage and while some consider "texting" light usage if the screen is on black text on white background the whole day, there goes the battery stats. Same with screen on sitting doing nothing (maybe displaying time)...
Should "Battery Life" be normalized or adjusted something similar to "Time Between Charges" divided by ("Time Screen Display is On" times "percent White pixel counts")? Are there any battery stats / device stats / display stats that can help figuring out a "Battery Life Index"?
Sorry for the random thoughts....

Actually I've been keeping track and the screen is on 3-4 hours per day, plus the haptic feedback, interrupts, etc. Doesn't take me anywhere near 30s to send a text message, few seconds TOPS for most of them and I never said it was light usage haha. Just asked if anyone knows of other measures I did not list which I may employ to extend it more.

The vooodoo kernel will help a bit as it uses a much more optimized file system so your phone will spend less time cache thrashing and reading/writing large downloads.
Essentially though it is down to how long your screen is on and how many accounts you have syncing in the background, also if you don't need full 1ghz for texting/calling smoothly then use setcpu with an ondemand or interactive type scheduler and set the max to like 700-800mhz...

This....
BUT i will say that the battery life on this phone takes a great big dump on the TB`s battery, now thats a bad battery life, i would consider myslef a heavy user i make around and receive around 100 calls a day, around 100 emails and around 75-125 texts per 8 hour working day
i can get through my day putting my charge on charge ONCE for around 30 mins, my thunderbolt had to be plugged in most times, 2-3 hours max for total battery death ( 3 hours is extreme generous, was more like 2 hours ), i carried 3 batteries with my thunderbolt.
The charge for me is great, on a par with my old galaxy S for battery life, if only they coukd give me iPhone battery life, for as much as people dont like the iPhone, it sure does sip the juice

Thanks!
Get Watchdog from the Amazon appstore to find out what's draining your battery. I believe it costs, but it is a thoroughly useful app
Don't think we can remove carrier apps until we have root...that said, you could try adb pull, but I'm not sure whether it will have any effect. May need root for ab pull, in which case we can't get rid of carrier apps :/ sorry

this has the best battery life ive ever saw. I'm in 0ma all the time the phone yesterday lasted from 530 am til 7 pm at night with a lot of text and playing games like homerunbattle 3d. If you play that game you know how much of a battery hog it is. Best battery life. Battery was soo good i barely charged it went to work with a 40% battery and it easily made it through a day with moderate texting all day!!
Gotta say... coming from a TBolt this thing is like sex in a tin can.
Idle is 1-2%/hr probably. I would get 10%+ on my TBolt at times... if not more. It was bad.

today is the first time I'm having issues. Only 4 hours since charge & down to 40%. The Awake time shows as 99% of Up Time. Is that normal??? Also, anytime I look at the task manager it shows wifi calling running even though I have it shut off
I've got an Asian model sensation (ie. 3g and not 4G model ) and I find my battery isn't really calibrated properly so its hard to comment on average percentage drop per hour. I've recharged my battery 3 times already and i find the battery stays at 100 percent for around 30 minutes of constant on web browsing, then it will drop at a rate of 10 percent every half an hour with constant use and will fluctuate.
To report on a rough usage breakdown, with all background syncing disabled, I managed to get 10 hours standby before my phone dropped below 10 percent. This was with 5 hours of screen being constantly on doing mainly web browsing on 3g and one 15 minute phone call using my wireless Bluetooth handsfree.
I can report the battery life with constant usage is better than what i got with ny hd2. Running android ROM, it used to do around 3 hours of constant web browsing before the battery will fall under 15 percent. In standby my hd2 used to drop around 1% per hour, which was quite excellent.

Those are the stuff I'm talking about, it appears that one of the settings and/or app is constantly using the processor, which causes the phone to stay awake even when the screen is off... I just haven't figured out which app is causing the problem.. I am suspecting it is one of the Tmo apps.
I'm looking at a full battery life of 11 hours, 49 minutes with moderate usage (some calls, decent amount of texting, some games). I use the app/widget "Battery Left" to do its own independent assessment of battery usage and life.
So far the battery reminds me of my early days with my Nexus One -- before I had it rooted and optimized and undervolted. Once rooted and optimized, I saw a good 50% increase (at least in battery life).
If you'd like some relief right now (before we get it rooted), I recommend Juice Defender on the market. It turns off data (among other things) every now and then to save battery, and with this I can squeeze out 18+ hours with moderate usage.
how are you checking the percentage? when I looked in the settings menu, all I see is a long green battery bar, no actual numbers. Or are you all estimating from that?
I don't monitor my standby time, but I'm sitting at what looks like 40% after 13 hours of fairly moderate usage during the day, I'm impressed.
Ive been getting about 9 hours out of a full charge. Had to put my phone on the charger today at around 4 o clock because it was dead. I dont have much more info other than that. I will keep an eye on my processes over the next few days. I have only 3-4 cycles on the battery though.
To check the percentage of the battery life u have to download some battery widget in the market.. I.e smart battery monitor or battery percentage s.th like that...
Sent from my HTC Sensation Z710e using XDA App
You can also check battery level by opening Phone and dialing *#*#4636#*#* and then select Battery information.
I'm using Juice Defender and I have to say it really does the job : my Sensation lasts More than one day and a half (30min calling a day, texting, Android Market, Angry Birds...). Without the app running it would last a day (Angry Birds drains...).
Juice Defender says it is increasing battery to 1,53% and it is very close from reality.
I've been owning the phone from 24th of May.
I think my battery is discharging really fast. I have power saving mode on and brightness at about 30%.
Wifi is always on"unless im sleeping" ram is at about 600+ all the time. Can anyone help me figure out
how to slow down the discharging, and are there any recommended apps for solving this issue?
Go to settings> battery and check battery use specs.
If you're getting more than 7 hours of screen time in a charge, you prob have nothing to worry about.
If you're getting less, check what else is eating it up

At heavy use with max brightness and screen always on batt should be worth 9-10 hrs of working time.
Some apps (esp. Weather apps with warning function as well as some widgets) actually suck away the battery like hell .
Get "better battery stats"and run it for a day and You will know which app/widget is the sucker.
On my old Note I had a "sucking " event after a ROM update: 30% in 30 minutes. With the experts here I solved this in minutes.: :laugh:

I think it would go down in 4 to 5 hours if im using it non stop with power saving on and 50% brightness.
That is normal I think nothing to be worry about

That said, I can probably get like 7-8hrs of good usage.
Watching videos, esp HD and on-screen widgets are usually the main culprits.
