hi guys i've been having a problem that i cant get fixed. ive asked some people and they are not sure what the problem, and also looked in threads and the fixes dont seem to work either.
i flashed the chadogr rom a while ago from cyanogen mod 7 becuz there were certain issues i was having with it.
when i had the chadogr sense rom, the battery would continuously die in barely no time at all, and when i looked at what was consuming my battery, "display" was always using at least 80-90%, and the phone would be dead in about 3 hrs or so.
got sick of it, and went to an aosp based rom called gingerbread evo deck 1.2w. it was very good and light on resources and battery life was good WHEN I DIDNT USE THE PHONE. but as soon as i started using it battery would drop so fast, but that didnt bother me, cuz sometimes i didnt need to use it. but there were somethings that i just couldnt stand with asop.
1. GPS never worked, EVER!! (i tried all the fixes to no avail) it was always searching for satellite everytime i wanted to use navigation.
2. it had awful signal strength (even wifi), constant disconnects, and always giving me this info that im internationally roaming (wtf)
3. a couple of other things not really worth mentioning.
i said eff it and decided to go back to sense, and decided on the synergy rom after reading the thread to great reviews.
i like the rom but im back again with those "high display" use problems again.
what is causing this and how do i fix it. there was a "fix" in the synergy rom thread but it didnt work for me. it said to go to the spare parts app and uncheck the compatibility mode, i did that and im still having those display issues.
here are some pics for illustration purposes:
this is the chadogr rom (sense), and after only about an hr, its down to 65% and look at what the biggest user is

sorry this is so long, pls dont bite my head off or yell at me , i dont know what else to do,
i dont have automatic brightness, screen timeout is set at 30s
im lost
pls help, and thanks alot guys
It's more probably a difference of the battery stats plotting rather than the drainage of the display. Display drains the battery most out of all the components in the phone, so that reading must be pretty accurate. If you're battery is draining ridiculously more over AOSP, which Sense ROMs usually do, than you might have a problem with the ROM or kernel themselves and not necessarily Sense, or it could be a more accurate reading for the Displays battery use. I am running Synergy Nightly 7/16 and my battery life is relatively good to CM7.1 RC1. And yes display is at the top at 66% at about 1/4 the time on(Ex. 2 hrs run time since charge, 30 mins display on). Turn of auto brightness too.
Also remember that it is displaying percentage, so the display being higher is actually a good thing. Your display uses the most power of everything on the phone, or it should be, when it is using a higher percentage of the total power available, it means that everything else is using less. The only way to get the percentage of display use down is to either turn the brightness down, or leave the display off as much as possible.
Click on display and you'll get an accurate reading of how much you actually used the display.
Synergy is awesome though, I went from 86% down to 85% when I woke up this morning. 10 hours off the charger and I wasn't even fully charged when I took it off. This thing is amazing with battery.
I have the exact same issue as the OP. I'm posting from my phone right now so when I get home I'll post a more detailed reply with pics but this is NOT NORMAL display usage. I'm getting sick of people telling me and others with this issue that its "just a percentage of what's using the battery and its normal ". Its not normal because this never used to happen to me and the display never used that much battery before. My battery life is horrible compared to a rom that doesn't do it. At most I'll get ten hours from a full charge and I can visibly watch the percentage drop as I'm using the phone. Even when I haven't touched the phone and the screen being off, the display usage will still be at like 90%.
It didn't use to happen, it seemed to just appear out of no where, the first time being with mikfroyo 4.62. I tried downgrading but no luck. I can only comment on roms that I have tried but it also happens with mikg and synergy and a few other sense roms. Aosp does NOT have this issue as I've tried a few differently ones. Currently using CM 7.1 and I'm getting at least 20 hours with heavy use.
I have been trying to get to the bottom of this for a few weeks but it seems that I just keep getting run around in circles. Now that I've seen other people are having this issue too hopefully we can get this worked out with some help. Its keeping me from using my favorite rom, synergy. I like aosp but it just can't match the performance and functionality of sense, oh and looks hehe. Like I said I will post up some pics when I get home to provide more evidence

Have you checked your wake time on the ROM? Wake lock issues are a more likely culprit than the screen when it comes to bad battery life like you described. Go to menu/settings/about/battery and look at your Up Time and your Awake Time. If they seem close to identical (even though you know you've walked away from your phone for a while and had the screen off, etc.) then you have a problem.
The most likely solution is a PRI downgrade to 1.77. Check your ROM's forum to see whether or not a particular PRI is suggested or not.

Its not a simple wake lock issue. My up and awake time are very different, just like they should be. Its not pri either cause I've changed it multiple times with the same issue. How would that even affect display usage? Every pri problem had caused high cell standby or android system but not display. I just bought system panel and I am going to let it run a monitor for a while and see if it brings up any red flags (using synergy). This is something a little deeper than a simple wake lock or radio issue.

Yep, sounds like it. All I know is that many, many phones (including mine) on gingerbread roms show very high display percentages. However, the phone lasts just as long as normal. The going notion is that gingerbread handles app and service power so much better than Froyo did that the display percentage simply has to be higher. That's how percentages work, of course. However, if your phone is dying at a much faster rate than normal, then yes, something is wrong, but I wouldn't be surprised if it has nothing to do with your display. Not that I have any clue what it might be, just sayin'.
It does it regardless if its a froyo or gingerbread rom. First rom it popped up in was mikfroyo which is 2.2. But weirdly it didn't use to do it on that rom. I achieved my best battery life (30 hours moderate usage) on mikfroyo 4.62.

I have three different phones.
Hero (rooted with CM7) - high display usage
Epic (Unrooted stock 2.2) - high display usage
Evo (rooted various 2.3 rom) - high display usage
All have high display except when I run Deck 1.2.1.
On my Evo some rom such as Sprint lovers (stock after auto root v2.5) 3.70 gave me high Android system, but most if not all gingerbread rom with the exception of deck all show high display usage including miui.
This lead me to think that high display usage is quite normal IMHO, just thought I'd share.

How high though? Mine and the OP display usage stays from like 80-90%. I can understand if its a little higher than everything else but this is extremely high. And why would extremely huh display usage be normal even if i haven't touched the phone and the screen is off? Its not normal because it didn't used to happen on the SAME rom. Like i said i used to be able to get 30 hours with mikfroyo 4.62, then this display issue came up and i cant hardly get 10 hours from a charge.

when i 1st got my evo, display was never the biggest power consumer, it was either android system, phone idle or something else.
its hard to believe the reading is accurate, when i know i havent even woken up the phone that much, currently the biggest user of my phone at home is wifi, yet that shows only like 4% or so.
oh and yes auto brightness is off too as stated on the bottom of my original post

I've had the same problem as the OP, specifically with Sac's Kingdom... Loving Sense 3.0, but the battery drain was a little much. Feeling your pain.
I'm going to PM myn and aamikam with a link to this topic. I don't think we will be able to figure this out unless we get some rom developers involved. Hopefully they actually take the time to read my message haha

One thing I noticed, in your pics your signal is very low, if your signal is low your phones gonna use alot of juice trying to maintain and/or look for a better signal.
Try checking in an area with a decent signal.
@OP...as long as your up time and awake times are diffrent Your phone is completly normal...1) when your using sense roms your continuously using your phone,so your display screen is on all the time. Hence the display so high. 2) when your using aosp roms..your taking long breaks from your phone..the flat lines on your graphs...your phone is sleeping,allowing more batt life..your in 20+ hrs of use..when your on sense your in 3-4 hrs of non stop use..it looks to me u enjoy sense more and can't put your phone down LOL..so the more u use your phone the higher your display % is going to be.

Ive spent the last few days fiddling and testing stuff to increase battery life. Here is what i have learnt...
(Im running R2BA026)
Firstly, personally i do not want to lose any functionality/performance in order to gain battery life. I think that if you are going to spend the money to get a phone with awesome hardware it should be able to run at full whack.
This guide will not be useful to all, but hopefully it will be handy to those in my situation.
This is a guide for what i have found to be the best compromise between battery life and user experience, with the emphasis being on user experience.
My specific goals are:
- I do not want to lose any performance i.e cause any slowdown/choppiness.
- I am only looking for a 24h battery life as i can charge every night.
- I want to be able to use my phone without worrying about battery. Specifically I never want to think "i shouldnt do that it might run down my battery". I should be able to use all the features on my phone without questioning if i can afford to.
-=-
In my experience using a task killer resulted in only minimal gains to battery life but it meant that opening up apps could be a lot slower and apps could be choppy just after opening them.
Additionally the idea of setCPU is a good one however when coming out of sleep or opening an app it takes a little while to get back up to speed. This also causes choppiness. Personally I find lag/choppiness a real pet peeve, it irritates me alot, so I do not use setCPU either. It is true that with careful set up the lag can be minimised but then the battery life gains are also minimal, so I choose to keep full performance and dispense with setCPU. Bear in mind that the hardware platform is already very efficient and well optimised so a software solution will pretty much be a straight trade of performance for battery life.
-=-
With those two common options out of the way, what else can be done to save juice?
Well generally the biggest consumer of energy is the screen. The simplest option is just to turn it down to minimum brightness, but in my opinion that is not a good solution, its too nice a screen to have dimmed all the time. Thankfully the auto-brightness does a pretty good job of keeping the back light at a good level. It can be a bit disconcerting if you enable it when using full brightness as the drop can seem somewhat dramatic but don't let that put you off, give at 1/2 a day or so and you wont even notice.
Other easy but important things you can do are turning the screen timeout to minimum and always turning off the screen (power button) as soon as you are finished. They are tiny changes but really do make a big difference.
-=-
Onto wifi...
I think there may be a bug with the firmware because if I disable wifi I get a HUGE increase in battery life when Im at home. I have good 3g coverage here and a 3GB allowance so I only need to turn on wifi when Im browsing the web or market, seeing as it takes seconds with the widget this option suits me fine.
I suspect that when the phone is connected to wifi it doesn't sleep properly so drains very fast.
Only turning on wifi when i want it made by far the biggest difference to me, and as it doesn't affect my user experience in any appreciable way I am happy to do it.
I think its a good idea to mention app/widget updates and refreshes here, personally i have all my widgets and apps set to refresh only once a day, that suits me fine because I can refresh them all manually very easily if I want to to be absolutely up to date and I'm not a twitter or facebook addict Most of my widgets are news/article based so once a day is perfect.
-=-
GPS, again this is rather obvious, if you don't use it, turn it off. Personally i use latitude so I have it turned on all the time. Android seems very good about only using it when it is needed and the phone seems to get a fix very quickly so in reality it doesn't spend much of the day being active.
Same goes for bluetooth, although I don't use it so it stays off.
-=-
Nothing i have said here is particularly revelatory mostly common sense but I have always had battery issues often with the battery lasting ~12 hours before asking to be charged.
Updating to 026 made a big difference and following these rules means my battery drains on average 2-2.5% an hour under normal use.
Normal use for me:
-Wifi Off
-GPS on (With latitude widget)
-Gtalk always running
-3 news widgets + timescape
-frequent texting
-moderate calls
-frequent fiddling
The phone is very very snappy, everything apart from timescape opens as near to instant as makes no odds, the phone is a pleasure to use. My battery life has comfortably doubled without the use of any apps or any loss of performance.
Mission Accomplished
Thanks
Cheers for that. Very interesting .
I definitely agree about the task killer apps, the OS does a perfect job at running itself!
One question, Am i correct in presuming you have 3g always running? Network mode set to GSM/WCDMA preferred? Ive been afraid to do this as i have it in my head that 3g eats up my battery for fun! I'll have to try it out.
Thanks again!
I bought an extended battery for my X10 the sloping sides stop it looking like a brick. The G1 always looked like a brick with an extended battery but the X10 sloping sides do serve a purpose.

Some additional tips based on my personal experience:
-Using a third-party task launcher helps too. Some may not agree, but it works for me.
-Use a third-party digital clock widget instead of the stock one. Again, YMMV.
-Use a third-party(AGAIN!) MP3 player instead of Mediascape. I'm using Meridian, and notice an increase in battery life when playing MP3s.
I like having some control so I run task killer but there's no auto-kill enabled and if I know the phone is just going to turn it back on in 5min, I don't bother killing those apps. Maybe I should just remove it altogether, but it seems convenient to be able to kill an app at will (I do it with windows sometimes).

I think the reason why you find that the stock one drains your battery is due to the "use network provided values" being checked in the date and time settings.
Interesting article. I am running 024 and my battery is life is poor. I managed to get seven hours use yesterday after a full charge. My usage throughout the day wasn't anything too crazy. Where I work I get only a standard signal (no 3G). I seem to get a better battery life.

I agree battery life is horrible. It makes me really miss my blackberry.
Even when battery life is low, charging it takes FOREVER, not to mention if you plug it in and play with it at the same time, it charges even slower.
My Blackberry Tour charged fully in what seemed like 45 mins from less than 10% batt life. I know they are different phones, but it just really sucks to me.
I'm debating going back to a blackberry now. The X10 and other android phones (and Iphone), are more toys than anything else.
/end rant.
hehe sorry
Thats odd, my phone charges pretty damn fast, just a few days ago i was pleasantly surprised that it charged from completely empty (id forgotten to charge it) to ~80% in less than an hour.

Quite interesting for me, I decided to add some statistical experiment about it.
Under my situation and environment. (I won't go in detail, sorry about that)
With SetCPU were 2.32% per hour without any usage.
W/O SetCPU were 3.18% per hour without any usage.
or approximately 7% maximum saving per day time. (for me)
My SetCPU only effected sleep state.
Not a big deal but still significant different, but it could survive for whole day anyhow.
I'm more interested about Killing app. I might try after this as I see many argument about it.

Ohh figures, good stuff! Always better to have some numbers to work with.
Do you not find that for a few seconds after waking up the phone gets choppy?
I would definitely be interested in seeing the stats with a task killer
Do you guys leave internet/gps on or something? I get 3 hours/percent on idle.

Yup, with SetCPU for sleep state, it was 'choppy' for a few sec, mostly effect lock screen and screen switching.
Hey everyone,
I just wanted to help out those people out there who are getting terrible battery life with their G2's. I made this thread because all of the other threads that have a screenshot of someone getting about 14 hours of battery life have just the screenshot and no explanation of how they got this great battery life.
This is after quite a bit of usage (probably about 3 hours of internet browsing and about 1/2 hour of angry birds
Obviously this will only apply to you if you are rooted.
Step 1: Download and flash this kernel.
Step 2: Set SetCPU to this:
NOTE: If you go any farther than 960mhz then the cpu voltage will be raised, causing lower battery life. Everything below and including 960Mhz is the exact same voltage with this kernel so you won't get any improvement by lowing the cpu freq.
Step 3: Disable profiles. ALL profiles.
^_^

Hello? Did this help anyone?

Thanks for this link! I'm trying this out as we speak. I was previously running the GODspeed 1.4 Overclock with ok battery life..so i'm curious to see how this works. I'll definately keep you updated!
I always have a "screen off" profile with the frequencies set to 245/500, and I get insane battery life. Went over 14 hours yesterday, and I still have 55% remaining when I plugged in. That was also on the stock CM kernel. I'm trying out the UV kernel right now.

It's only been a few hours that this has been posted (and at least in the States, a Sat. morning). Just give it some time. Also, I think quite a few people are running this kind of set up already (based on the numerous discussions seen in the various rom and and kernel threads anyway), so they probably aren't inclined to reply/vote. Even if they weren't doing this, you probably can't expect any results from people for at least a day or two (unless their battery usage was really bad to begin with, they aren't going to know how much this helps until after the change has been in place for a while).
Just a heads up, Pershoot updated his kernel so that the voltages from 768-960 are now the same as at 979, so you might want to update the guide. Also, just wondering why you recommend the performance governor over on demand if you are looking to improve battery life? Won't the performance governor stay at the higher clock speeds for longer periods of time than on demand? Or did you think this was an acceptable tradeoff (as in things don't run as smoothly for you on on demand and you felt the extra power usage was negligible). Just curious. I had always run on demand or conservative for battery life, but conservative is no longer supported in the Pershoot kernel (and some times led to slight lag in my display turning on).
Also, I'm not positive on this since I don't use Sense roms, but I heard that because Pershoot's kernel was designed to run specifically on AOSP-based roms, it may cause problems with Sense ones. Might want to either put a warning in your guide or verify that this isn't the case.
Ok, I'm following this guide, just flashed the kernel, it took more to backup than to actually install the kernel, on CM6.1.1, will check in tomorrow if I see any improvement, because I used to get only about 6hrs of battery life as I was before.
I always have wifi all day at home since my carrier (Movistar Venezuela) does not have 1900/2100 frequencies.
Thanks for the information. Although it is common.

It's only been a few hours that this has been posted (and at least in the States, a Sat. morning). Just give it some time. Also, I think quite a few people are running this kind of set up already (based on the numerous discussions seen in the various rom and and kernel threads anyway), so they probably aren't inclined to reply/vote. Even if they weren't doing this, you probably can't expect any results from people for at least a day or two (unless their battery usage was really bad to begin with, they aren't going to know how much this helps until after the change has been in place for a while).
Just a heads up, Pershoot updated his kernel so that the voltages from 768-960 are now the same as at 979, so you might want to update the guide. Also, just wondering why you recommend the performance governor over on demand if you are looking to improve battery life? Won't the performance governor stay at the higher clock speeds for longer periods of time than on demand? Or did you think this was an acceptable tradeoff (as in things don't run as smoothly for you on on demand and you felt the extra power usage was negligible). Just curious. I had always run on demand or conservative for battery life, but conservative is no longer supported in the Pershoot kernel (and some times led to slight lag in my display turning on).

I'm just reporting what I found. Perhaps the ondemand governer is using more power because its constantly checking the cpu utilization?
Sent from my T-Mobile G2 running Cyanogenmod.
Here's some:
Use the stock charger. I believe the stock charger provides power at 5.5V (I'd have to check to know for sure), because that is the voltage the battery was designed for. A lower voltage could mean that your phone *thinks* it's charging at 5.5V and will stop charging when it *thinks* it's at 100%, while in reality it might only be at 80% or less. Higher voltages could wear out the battery faster but provide faster charging times.
Calibrate your battery. Roughly once a month, let your battery completely runs out (after it shuts down again, turn it on again until it's fully out), let it charge while off, and repeat at least once again. This may have a significant effect depending on how you use your phone
Turn off unneeded services while not in use. Having WiFi, Bluetooth, 3G, autosync, facebook sync, widgets, etc can harm battery. It is super simple to put toggles in your notification bar with either CM, MIUI, or Enom's roms that it is pretty much a painless way to dramatically improve your battery life. Facebook sync can be a huge waste too if you have it updating automatically, try instead refreshing it manually. Get rid of widgets that "seem" useful, but in reality just take up ram, download useless data, and take up space. I mean, I like to be able to know the temperature or whether I should bring a jacket, but do I really need the news to be right there in my face 24/7? Widgets like that would have to be constantly downloading data to be even be relevant, and IMO it is easier to just open an app. You can leave GPS on though, as the phone only activates it when necessary.
Update your radio to the latest available. This one is just common sense. The radio is basically the driver which your phone uses to connect to the cell tower, so wouldn't it make sense to have the newest, most efficient radio? I use the .02.17 radio and it is definitely better than the radio that came with the phone originally. Use Gfree before you switch because getting s-off with .02.17 is a pain in the butt.
Those are just some of the things I've realized with both my G2 and my G1 before it.

No, task killers don't work at all on Android. Especially so after 2.2.

I'll get out my multimeter later to test this.
However, I don't think that's true. It probably just figures out whether it's on a usb port or ac charger by seeing if there's power on the DATA lines inside the usb cable. iPod Touches and iPhones REQUIRE this power so they recognize it as a usb port, otherwise they WILL NOT charge. This explains why, if I plug in my G2 into a charger designed for an iPhone (same specs, 5V out at 1.0A) it will register as USB to the phone and will charge quite slowly.
Again, this is all going off assumptions. I'll put my thoughts up against my multimeter readings later. ^_^

So yesterday morning I woke up at 9 am and went to ihop, I disconnected my phone from the charger at around 920 at 100% by the time it was 1040 ish I randomly looked at my phone and noticed my battery was at 33%?!?!?!? And I went crazy:O yet when I got home I charged it to around 83% disconnected at 730..then at 12 am when I got home I was barely at 61%?!?! Whatsoever the reason for this?!?!?!

I had this very problem with my G2... it fixed itself like yours did. I think it was probably either skype or qik, as the problem went away after I uninstalled them. You might have had a hung up application running in the background.

I suppose I'm one of those people who had no issues with their battery, but I recommend using a screen off profile for SetCPU. In doing so, I can effectively go almost a full two days on a single charge, but this is with minimal usage. Such as texting and browsing the web for only a few minutes.

I am using ava z3 and caulkins modded(uv and sdfix) HTC 15 kernel.
I only get about 11-12 hours of battery life with moderate to light usage (20 mins of phone, 25 or so texts and maybe 25 minutes of total web browsing)
I see all these posts of people having battery life lasting 20+ hours...
I have setcpu drop my clock when screen is off, random advanced task killer taps, autosync off, gps off, Bluetooth off, and only use 3g all day. Anyone have any combos that I could try or possibly some tips to get my bat life higher?

No clue, MIUI doesn't give the awake vs. uptime like a sense rom does. It was with moderate use, maybe 30-40 texts, a bit of browsing, maybe 30 minutes of mini squadron and a few short phone calls.
Myn's Warm 2.2 RLS5 with netarchy-4.3.2-cfs-nosbc-havs-more has done wonders for my evo. I use SetCPU and set the govenor to smartass, have one profile for screen off (384max, 128min smartass). I can get about 7 hours of uptime(20 hours of total up time= that averages to 21 minutes of use every hour...) with 1.5 hours of that being phone calls, about 50 texts a day, checking 3 e-mail accounts (gmail's push) and reading my hundreds of RSS feeds with NewsRob.
The only other time i got similar results was with Warm 2.2 RLS4, HTC kernel #17, and some very aggressive SetCPU profiles. and similar usage.

Ok so ive been changing different kernels just to see if i can get different results. Now im using KingKlicks #12 w/ myns rls5. I use my phone alot & am just looking for SOMETHING that will help my battery life.
So the other day i was in this super retardly long useless meeting. Less than 10 texts, no internet, no apps no nothing. 4g, GPS, Wifi & bluetooth all off. Granted that isnt my regular useage (I really use my phone) but this is the best battery life i could get. (SetCpu on w/ a helluva lotta profiles)

3 days??? wait wait...either thats photoshop or you've got a different phone than me!!! In any event im flashing netarchy as soon as i finish typing this!!!
Do you use your phone? Like heavy useage? Or is that 3 days with absolute minamal useage?? 4g, wifi, gps & everything else off??
The question is, what is the definition of best battery life... How long the battery will last with the phone doing nothing? If so, I can get a good 4-5 days using the setup in my sig with just a minimum of texts, calls, and emails, while on wifi.
However, actual practical usage, including 3g, 4g, web, text, calls, etc. Results in a good 1-2 days of battery life. I think once a user has all the bugs (rogue apps that are causing wakelock issues) worked out, that user should focus on optimizing the system for best results for the way THEY use THEIR phone, not the way someone else uses theirs.
^^Agreed i am trying to find the best fit for the way "I" use it however suggestions are welcome. BTW you get 4-5 days 'cause you've got the extended batt. I wanna squeeze every last drop of juice out of my stock battery!! If you can help me there then by all means...please do!!!
Edit: side bar i just flashed netarchy's 4.3.2 cfs-nosbc-havs-more-universal and everythings fine but when i plug my charger in AC or USB it throws my phone into a boot loop....Any ideas?? Btw yes i am gonna find the netarchy thread and ask in there as well.

What's the best way to find the wake lock issues, are you referring to maps, voice, or other random apps running in the background? If so what is the best way to keep these apps but put an end to the wakelock issue.
I am still running ava z3 but I flashed the netarchy 4.3.2 cfs-nosbc-havs-more this morning, downgraded my pri and nv because netarchy said to for battery issues, gave it a full charge from 0, and my battery was garbage... 5-6 hours with a moderate use. Calks modded htc 15 w/ uv and sdfix worked way better, but still can't find these magic 20 hour battery lives that I am dying for.
Reflashed the new pri, nv, and Calks modded 15 and my hunt continues, about to give myns a whirl despite liking ava z3 a lot.
How simple is myns, bloatware gone, fairly simplistic, pretty snappy and lag free? Difference between rl 4 and rl 5?

Use the battery history function in Spareparts to see what's causing wakelock. As for ways of dealing with it, that's up to the developer.
I don't have too many apps on my phone, just the necessities. Of the main apps I use, k9 and handcent both had issues.
With k9, any time I'd receive an email (using imap), the phone would stay wake locked for 60 seconds. This may not seem like a lot, but after getting many messages throughout the day, that could add up to an hour or more. I experienced this both with fresh 3.5.0.1 and evio2 1.75. When Evio2 1.7.7 came out, I was hesitant to switch - I'm not one that flashes roms every other day just for the hell of it. I already had the phone set up and configured. Decided to give it one more shot, I installed 1.7.7 from scratch and started reinstalling apps.
Through out the process, I was very careful to monitor wakelock state. For what ever reason, k9 was no longer causing wake lock. Something in 1.7.7 changed. It wasn't kernel related because I've tried way too many kernels with similar results. So now, the only wake lock is when the program actually receives an email. Usually 1-3 seconds per email received.
Now with handcent, there is a known issue if the popup function is enabled. Anytime a text is received, with popups enabled, the phone enters a wakelock state until that text is acknowledged. This occurs even if the only popup task is to display the text, and NOT turn the screen on, or flash the led. The fix? Disable popups in handcent. I've posted on their forums, but haven't gotten any acknowledgment. I'll continue to use the program, but without this functionality.
For other programs, best bet it to try to narrow down the conditions causing wakelock and either work around them, or work with the author to try to resolve.
Any as for stand by time, I'm sure even with a standard battery, 4 days is possible if the phone is idling the whole time with data turned off, and minimal or no other usage.
As for kernels, there are other factors at play besides the kernel itself. These include the governor in use and its parameters. Two otherwise identical phones with the same kernel and governors, but different governor parameters will result in different battery life.
In the end, I chose to stick with the conservative governor.
These are the governor parameters I changed in the init.d folder
Filename: 01cpufreq_screenstate_scaling
Code:
MAX_CPU_SPEED_VDD="921600"
MIN_CPU_SPEED_VDD="245000"
#MIN_CPU_SPEED_VDD="384000" DEFAULT
#MAX_CPU_SPEED_VDD="921600" DEFAULT
CONSERVATIVE_SAMPLING_RATE="50000"
CONSERVATIVE_UP_THRESHOLD="80"
CONSERVATIVE_DOWN_THRESHOLD="55"
CONSERVATIVE_FREQ_STEP="10"
#CONSERVATIVE_UP_THRESHOLD="65" DEFAULT
#CONSERVATIVE_DOWN_THRESHOLD="35" DEFAULT
#CONSERVATIVE_FREQ_STEP="15" DEFAULT
These settings were not arrived at trivially, but were changed slightly one at a time, then tested by using the phone. I was looking for decent response/user experience. I was also trying to get the phone to utilize a larger range of cpu speeds than originally programmed into the ROM/kernel. Google the different parameters to understand what they're referring to.
Edit: I'm also using the -100mV undervolt script as opposed to -50mV that the rom originally comes with.
Hey guys. Battery life honestly, is the most important thing when owning a smartphone. Everyone gets different battery life apparently. Some are great!! Some are.. well..
Anyways, my whole point of making this thread is so that we can discuss our various battery lifes. See who has the best. Who has the worst. And why we have such differences! Maybe we can make solutions and we can all have great battery life.
Please include what ROM your running, what kernel, if your overclocked, and little things you might find suitable to add.
For example this is for me:
I'm running Acer liquid ROM 1.1 with pershoots latest .32 kernel. I can get maybe 8 hours out of my battery with extreme mild use. I'm currently trying to recalibrate my battery with the help of bongz ( thank you so much!) I have my screen usually dim, nothing syncing from what I know of, bluetooth never on, gps never on, wifi only at home.

I'm running GingerVillan 1.5.
Battery life on standby is great - probably around 1-2% an hour. However, when I start using the phone, that drains QUICK. Generally I get around 12-14 hours out of a full charge with mild usage, including Phone Calls, Texts, 1-2 rounds of Words with friends, etc. WiFi is always off, bluetooth is off, GPS on. Stock kernel, newest radio near as I remember. Facebook and Google are the only two accounts.
I previously had a Vibrant that seemingly got better life - with mild use I could easily get 18-20 hours. However, having a keyboard and working GPS is worth the charge every night. The G2 could have gotten a couple hundred more mAh battery, if you ask me.
im running cm7 nightlies
my battery life is pretty good when not on. maybe 1% every 2-3 hours when off and in my pocket(set to absolute minimum via setcpu). with mild to extreme use i get ok battery life of about 4 hrs (starting at 80% usualy). im overcloacked to 1.8ghz ut have it set via setcpu to max out at 1.1ghz. i have gps always off, wifi always off, brighness to auto, and bluetooth off.

Sorry, but battery life threads/posts are always such a joke. So many things effect the battery life that it really isn't as easy as just posting your ROM and Kernel and call it a day. Every single setting in your settings menu, every app you run or have installed, screen on/awake time, BT/GPS/wifi/3g/4g connections, and even just general areas that you use your phone pertaining to their signal strength can effect what your battery life is. Unfortunately, there really is no way to figure out what the "best" battery lives are. It really takes your personal preferences and some of your own tinkering in order to get your configuration just right. You can go into any given custom ROM thread and find someone claiming 30hrs of battery life.
Sorry to be a downer. I (personally) just get really tired of people posting battery life screen shots because there are an extreme number of variables that affect it. I think it gives people false hope of looking to switch to a completely new ROM or change huge numbers of things and expecting to double their battery life.

I just noticed that the battery life of my DesireZ is greatly dependant on where I am....

when I am at school the battery is often almost empty at about 5 pm...
maybe because of the bad coverage at school?

I still don't get why people care about battery so much with g2. I got 2 extra battery and an external wall charger all for 10 bucks on ebay. why not use android to its full potential without ever worrying about battery for $10?

It's a hassle to take off the case (in my case an Otterbox) every time to swap the battery out. Added with the looser hinge, you might accidentally snap something that you don't want to. Would rather have one big battery than multiple smaller ones.
Understood. I don't ever use protection covers. Didnt even know tHere are the kind of cases not interfering with keyboard pullout...

I want the Mugen battery, my G2 has been quite crap battery life for the past while, I wonder how much this one will help
No complaints here.
Just thought I would throw down my stats as well:
I can usually eke out a good two or three days from my G2. Some things of note: I'm on Wi-Fi with UMA at home, T-Mobile's home network (EDGE) when I'm in the town in which I live, but as soon as I leave town and head towards my place of work, I roam on EDGE all night (with roaming data always turned on) until I get back home. I don't think I've even seen the 3G or H indicators light up on this thing. Got to love the rural life. I leave Wi-Fi always on, in case I find new networks, I leave GPS always enabled, since it really only activates on Google's home page anyways, I use the 30% brightness setting that is the default 'low' setting via the HTC brightness widget, and Auto-Sync is always enabled (Facebook, HTC (weather once per hour), Google). I use the default 1 minute screen timeout, and I use the lockscreen that comes with Poweramp (which I use to listen to music on my drive to and from work via an FM transmitter.)
The capture below shows 2d 14h 2m 30s since being unplugged, at 7% remaining. I use Virtuous 1.0.1 with the stock HTC kernel and the stock T-MoUS radio. I am also using the stock HTC battery that the phone shipped with. I don't feel the need to overclock, as my last phone was a BB Pearl, so this thing is light years faster already.
The only time I really eat up my battery is when I play Wordsmith, because I'm always staring at the lit screen trying to make fancy words.
And while you're right, there are way too many variables when it comes to battery life and usage and signal strength and what have you, it amazes me just the same that others are fine with 8 hours of battery life and choose to carry around extra batteries. Sure, you have a mobile Linux box in your pocket (awesome!), but that's also why I keep a desktop PC at home. To each their own, though, no harm no foul.

I've been using it for 2 days and so far I have nothing but good things to say about it. The battery life so far has been top notch. My phone has currently been off the charger for 15 hours and 2 minutes, and I still have 41% battery left. It's very responsive. Everything works on my HW003 Evo. The one problem I have discovered so far is that when I record a video, once I'm done it force closes the video app. But the good thing is that the recorded video is saved intact and I can re-open my camcorder app immediately if I want to record another video. So it's really not a big issue. Other than that everything else sems to be working very smoothly. I have Go Launcher EX running on top of it and everything is super-fast. So far I'm really loving this leaked ROM. What about you guys(and girls)???

Well, I took it off the charger just after midnight last night, and I woke up at 7am. So 7 of those hours it was resting. But since then I've been to the gym and listened to music the whole time, sent a few texts, received about 30-40 texts from twitter, browsed the web for some of the links, viewed some android central youtube videos, updated some apps in the Market, made 2 phone calls, etc.. The point is with my last ROM and kernel, normally I'd be at about 15% battery by now.. There seems to be a noticeable improvement. But I posted this thread because I'm wondering if it's my imagination or if anyone else is having similar experiences.

Sure your using gingerbread? That battery icon making me suspicious. 0_o
Asop ROMs do typically use less battery than sense ROMs
LOL! Horrible battery life considering you haven't made one call.

Pretty decent
A drop of Chuck Norris's semen was placed on Android OS. We now have CyanogenMod.
Where's a link for it? I wanna try this out and put in my .02!
Fyi my g1 only lasted 4-6 hours on a charge using stock battery, I turned off the radio and let it sit in my sock drawer it stayed on in stand by for nearly a week on that same battery.
These threads bragging about battery life are just BS, im sure if I want all day not using my evo I'd also get 16+ hours on a stock. I typically get a good 14-16 hours using my 3000 mAh battery and being constantly on my phone.
I noticed a lump in my battery last night (SBC maybe?) And now im back on the stock battery, this is my 3rd time today its back on the charger, my point? None but these threads don't mean a thing unless there's any really useful information to significantly extend the battery, especially to us users who do use our phones and not just let them sit idol all day.

If anyone says a phone can last more than 4-5 hours, then using a phone to them is turning the screen on to check the time, then quickly turning it off.
Anyways link? I wanna use Sense with Gingerbread.
He is obviously using his phone because 40 percent of it is the display

Last I checked there's a few in the development forum, but they are ports and a work in progress and have a lot of things broken. As son as there is a stable gingersense im all over that.
I loaded the leaked 2.3.3/sense 1.0 that tmartin put together. It is 100% functional for me. Some people were having issues with the screen staying at 100% brightness, and the camera acting strange. I think that may have been a variety of factors, wipe quality, hardware number, and screen type.
The rom was flawless for me. I have a 3500 battery and used my phone like a crackhead for 15.5 hours before the battery died. I was web surfing most of the time, and reading the leak thread that hit over a 1000 posts in a day before the op locked it up.
I am now using the misfit gingersense rom, and it is working 100% for me, apart from some very minor black on black text when word suggestions pop up using swype.

I flashed the tmartin 2.3.3 sense leak as well. I liked it for the most part...but it wasn't anything really special...some menu changes and it did have the nice fast boot feature. Sense was still a little sluggish when scrolling through home screens. I flashed back to cm7....what I do miss is the stable 4g that I do not get with cm7 final.

Wtf are you talking about!?
A drop of Chuck Norris's semen was placed on Android OS. We now have CyanogenMod.
This post was not just about battery life. That was just one aspect of it. I posted it to get feedback from others who are also running the ROM put together by TMartin from the leak. I still don't get why people get so funny acting when it comes to others talking about how long their battery lasts. If you don't like it or don't care to hear about it then move on, as it may not be for you. But others may be interested to see if it improves their battery life. Remember, every post here isn't catered just for you. The world is bigger than just you. Anyway, I use my phone quite regularly, whether it be browsing the web, viewing video, texting, listening to music, etc.
I also forgot to mention that I'm using the stock battery.
For those who asked where they can find the download, here ya go. It's linked in the first post:

Dude, your battery might have cancer. You should do a battery self-exam at least once every month. It's best that you do it in the shower so that the battery can hang low. Make sure you roll your battery through your fingers to check for any abnormal growth or lump.
If you feel a lump or that the shape of your battery has changed at all, don't hesitate to see your doctor. Remember, catching battery cancer in the earliest stages gives you a much better chance at survival!

I layed on a flat surface and noticed it rocked a little bit, so yea it has a slight deformity. Dr. Abu ghraib can have a look at it tomorrow.
I flashed it and been running it for a few hours now. Its alright, nothing ground breaking or impressive. Im kinda disappointed about no vertical battery or the on/tv off effect like the asop roms have. I thought I was gonna see that in gingersense. No big deal though, its same ol sense on gingerbread. I did notice some improvements in the browser. Fair enough, its cool, but still a little buggy.
Screen dimming works for me BTW, on my 0003.
Tomorrow will be the real test as far as the battery goes.
What bugs have you noticed?
