[Q] Battery useage questions - G2 and Desire Z General

Finally got my desire z, it came with 2.3.3 unfortunately. So as yet not rooted or anything as I don't have the time just now.
Was just wondering what people's current drain was, mine seems to be around 32mA on standby which shoots up to between 200-350mA with screen on, brightness at 12%.
1. Would this be considered normal for stock?
2. I also am having the dialler high useage issue, tried most of the fixes but still quite high, was this ever resolved properly?
3. Thinking of romming to virtuous sense 2.0 if it will improve the battery drain, can some of you give rough screen off current drain figures please? Especially sense based roms as that's what I would be using.
Thanks.

I used the 1350mAh battery for a long time and then finally caved in to get a Mugen Power 1800mAh. Since then Sense based or not my drain doesn't go below 15% for a full day Wifi (always on), Data (always on - when no WiFi) and Bluetooth on for 6 hours (during travelling).
I would suggest you do the same to get the peace of mind everyone deserves but HTC wasn't caring enough to pack in.
With a 1800mAh battery you don't even have to worry about anything, no matter what you try.

Interesting. It really makes that much of a difference does it?
Where do I get them?

Yup it does, mine is a 1900 mah from chi chi tec

I got my Mugen 1800 from eBay. But you can get it from their website directly. Beware of fakes! If it's too cheap to be true, it is.
Here's a tip, you really don't need much brightness indoors and turn off GPS, wifi when not using it, and screen timeout to like 1 minute.

Way ahead of you, my brightness is always 10% ish, same with gps and wifi, fb every 4 hrs and mails every 6.
I'm now rooted with S-OFF on gingerbread stock. Gonna install cwm and maybe try a different kernel. Any recommendations as to one which will work with stock?

No idea on the kernel, but I really do suggest a bigger battery. I just went back to the stock one for a few days and it was noticeably less.

Just use glite problem solved lol

I'm using bulletproof miui and my standby sits around 28mA with around 150-250 mA regular use. My battery lasts a full day with medium usage (4h screen on, wifi on, 18-20hrs unplugged total). I would say you're sitting a bit high with your battery consumption and could benefit from an undervolted kernel. I have my cpu clocked at 1ghz max these days..
Hope that helps!

I'm thinking my battery just hasn't settled yet as I'm using the battery monitor app and it tells me I'm getting a 32mA draw with screen off but my battery is lasting only around 18 hours with light use and a lot of standby time. For a rough calculation: 1300mAh/32mAh = 39ish hours (standby), deduct 10 hours for messing around, I should be getting at least 24 hours I would think (very rough calculation).
Have only charged it maybe 5 times so far, its probably still being worn in as it seems to drain damn quick on standby at 32mA.

Possibly, do you know your voltage levels for each clock speed? I can get a good 35+ hours with light use and standby at night (~3 hours screen on with wifi connected always)

I'm still on stock just now. Just realised that 'always on mobile data' was on, so I have turned that off as my sync apps will still work and I don't use push email. I'll try that over the next few days and see if it makes a difference as well as the battery getting charged with more cycles to break it in.
If that still leaves it to be desired, then I'm gonna put virtuous sense 2.0.0 on and use underclocking as that made a massive difference with my old wildfire.
What rom are you using bik_jack?

I'm using bulletproof miui but was getting roughly the same voltage numbers with cm7 nightlies before I switched to bulletproof in June.
Both underclocking down to 368mhz with the default undervoltage settings used in tsubus' kernel.

i made a barebones stripped ROM based on the newest tmo OTA, i made optimizations to get better battery life, and stripped tons out to get the most ram possible, and keep the ui fast and snappy.
my newest version 1.3, offers the best battery life in any rom that i have ever used, its super fast (no need for OC), offers the most free ram and is located here :
http://forum.xda-developers.com/showthread.php?t=1324616
give it a try! im sure it will get u more battery life

Of course, now I've realised that my network (3uk) no longer have a 2g contract with orange, so all this setting does for me is stop me receiving txts and calls with it off. Tch. Looks like I will be trying virtuous after all.
The standby battery drain doesn't make sense at all, almost like my battery isn't really 1300mAh.

I use an Anker 1600mAh battery that I got off ebay in my DZ. The seller had a sale of 2 going on for $15, not a bad deal. link to it is here
It's listed for the Incredible 2 / Incredible S, but it seems those batteries are a perfect fit for the Desire Z / G2. Doesn't need any aftermarket casing or modding.
Right now, I am using the ICS beta by tazinator and yesterday I got ~12-13 hours of playing around with it very heavily. My battery can last 22-28 hours with moderate and light use on a normal day.
Sadly, I don't have any if those issues you listed, Dialer usage and such even with CM7. Used to use virtuous sense but went over to AOSP/CM7 instead. Found AOSP being more nicer on the battery, but that's just my feeling - I tend to think Sense drains more battery.

Yeah I think sense is a bit worse on the battery but I've really come to love sense, never really got on with cyanogen roms.
Turns out I was wrong about the data always on and my provider, it all works so I'll keep testing that before I start with roms.
I know mugen batteries are supposed to be good, any other recommendations for brands? I'll check the link out.
UPDATE: If battery monitor is to be believed, my global standby estimate is increasing with every charge, so maybe it is just a case of breaking the battery in. Now at 21.5hrs, I'll continue to monitor the situation, this might also be due to the change of data setting as well.

WTF is up with the EVO battery!

first off, i love this phone. no joke, but the battery is well...laughable to say the least. on my HD2 running android, i get double the battery life and they HD2's battery is a 1200 battery, the EVO'S is a 1500. and android boots off the SD CARD and has NO POWER MANAGEMENT on HD2'S. my evo dropped to 54 percent battery today in 3.5 hours. no wifi, no bluetooth, no GPS and no 4G...all im saying is... WHAT THE ****!
It gets better. Load up some custom kernals + setcpu and you'll get great life. I'm running CM6 + snap 8.2 and it lasts the whole day with moderate use.
Sent from my PC36100 using Tapatalk
There is plenty of info on battery issues with EVO.
First... I would recommend rooting.
Second, use the FRESH build based off the new OTA leak.
Finally, change Settings / Mobile Networks / [uncheck] Enable Always-on
Then... ALWAYS keep your WiFi radio on. Add your home network if you have one... and wherever you go, add whatever hotspots you are in proximity of.
And if you ever consider doing a new build, backup your WiFi access point data via Titanium Backup before you do.
That should just about cover it... You will get a full day of use PLUS some out of that battery.

i rooted my phone within 2 hours of purchasing it...i will look into what you mentioned later. im gonna condition my battery for the 4th time in 5 days..
PS those 3500mah batteries on ebay for 10$ and the same 2000mah batteries.
If you get one, get a seido. I just bought 2x1500mah batteries from tuttoit, great backup batteries... charger too 9.96$ shipped.
Oh and I am getting great battery life with snap and cyanogen's rom.
yeah i am going to look into all the batteries, and i love sense, that is why im not on CM6. all my other phones are running it (G1, MT3G HD2). now that i have a phone that runs sense naturally, i dont wanna change it. i love sense! and this thread was just a way for me to vent about my crappy battery.... lol

When you rooted it, did you also flash the newest radios? Trust me on the fresh build.. it rocks... but also, most importantly, use WiFi whenever possible... and turn off "always update"... those are all the most important.

No when I got my evo I was clearly.told and shown a doc from sprint (the manager over mobile area is a buddy) to tell everyone to expect 6 hours of battery life with normal use. I was able to squeeze out 8 - 9 myself. I know people say conditioning the battery is a waste of time . IMHO do it I noticed a nice increase in battery life. I have to laugh at people who get pissy about battery life when they are holding a mini PC.
Myself i avg. 18-20 hours a charge with normal use. I have 2 backup batteries so I don't worry to much about juice
from the fade
I really dont feel the Evo is a bad phone h, hell I love the damn thing . I just feel HTC kinda screwed up things in the process . One telling customers to expect 6 hours of use is alittle of a joke . Who the hell only works six hours a day ? Or is that six hours also include you getting up getting ready for work then coming home before you go to bed ? Second , its pretty clear the Evo has a bug in its charging system . People have reported that using stand alone wall chargers to charge the batteries they are getting improved life out of the batteries (Sorry I have never removed a battery from any cellphone I have had in the past to charge it and not gonna start now) . Third yes the HTC Evo is litterally a pocket pc with capabilities most phones dream of having . Then why the hell did they give it a 1500mah battery ? Thats like strapping a 55 gallon drum of fuel to the space shuttle and saying "Yeah this outta make it" . Sorry for my rant had to get it out (plugs phone in to charge again) LOL
OP, I like you, you're funny
A couple things..
1) Why do you have your CPU governed below 700mHz while awake??? You won't save battery that way, your phone runs at a gHz, use it!!
2) Setting your min/max both at 245 on sleep will actually decrease your battery life and your phones wake up performance, maybe not much. Capping your phone at 245 when asleep makes it a harder transition to awake because it makes that sudden jump when you wake it up. Setting your max somewhere over 600 on asleep, and setting it to OnDemand will ease the transition from sleep to awake.
There is no shortage of battery life tips but here's one: The auto rotate function polls for g-sensor status like once every 15 milliseconds. I use a switch on my homescreen to turn it on when I want it and keep it locked in portrait when I don't need it. This will help conserve some juice
I'm only scratching the surface here, I'm sure you do realize what a wealth of info there is on the subject already. FWIW, I use the crap out of this phone and I consistently get 20+ hours out of a charge. Good battery performance is achievable!

Battery Life

Hungry Man ~
Lately I've been running the latest update of the same ROM (Nonsensikal Froyo - now 15.2) without any CPU apps (no o/c'ing through script either), no autokiller, no battery tweaks (just Juice Plotter) only 1 widget (Fancy Widget Pro), JIT enabled, VM heap @32, compcache @18 (default) and depending on which app I look at, TiB or RE, I have +/-110mb of free RAM, very minimal apps. Also, I upgraded to CFSv9. I even bought a Seidio Innocell 1750mh extended life battery. I recalibrate my battery after flashes ....
Oh yeah, a little more info, I am not a power user, just an average user with poor to ok reception, I tend to use wireless at my house b/c reception out here in the woods ain't good, but turn it off when not needed. I use airplane mode during sleeping hours as well. The max of my battery usage is Display, then And OS.
Ok, now the question ..... If I don't use airplane mode, I get maaaaaay-be 6-8 hours of average phone usage, usually less !!
What finally broke me to PM you now is that (i recently put numbers on my battery icon) while typing a text message earlier (a few minutes tops, not on wireless) I watched my battery click down from 50 to 48 !!!
When I charge my phone full & I easily lose 10% in half an hour (I've tried this with SetCPU, JD, CBT, Super Power, CPUBoost Lite - I think you get the gist) ... and not including airplane mode, I NEVER get more than 6-8 hours of battery life !!!
Is there any knowledge that you can give me on this issue or have I pretty much exhausted my options ? I am this PM short of resigning to crappy battery life
Many Thanks for your time ~
Matt

What does the phone/Spare Parts say is using all the battery? Have you tried flashing and then using the phone without installing apps (other than the essentials?) Are you leaving the phone idle, screen off, and noticing the same big drop?
You could try going to stock for a bit to see if it improves...or trying a different ROM. Maybe you have a dud battery?
Edit: Sorry, you may have meant this to be directed at someone specifically.
Just an observation. If you're not using anything to overclock the phone maybe the battery life would be better if you at least underclock it. I suggest Conap's CPUBoost Lite, free on the market and here. Just set the minimum frequency to 245760 (my suggestion), and I currently have the screen off Minimum to 19200 and the screen off Maximum to 480000.
Also, I used to use Juice Plotter. I theorized that maybe Juice Plotter wasn't great for my battery itself.

I noticed the same thing when I used Juice Plotter. I got significantly less battery life when i had it. Try deleting Juice Plotter and see if you get more life out of your battery.
well you've noted your in a poor coverage area, and that is your problem, nothing can completely fix other than moving, but you may want to research flashing a new radio, becareful and check your md5 hash sums

Actually, the Verizon Network Extender can definitely help without moving. http://www.verizonwireless.com/b2c/store/accessory?action=gotoFemtocell
It's $250, but probably a lot cheaper than moving, and it should help with battery life. It does with me - I get 24-32 hours on a 1750 battery, with WiFi on all of the time (I have the old, non-3G extender.)
I'm running Tazz Froyo and get a minimum of 24 hrs on stock battery. I would try changing roms.
Battery life on my eris was never good, that's why you buy a extended battery. I have the biggest one that they have on amazon and my battery can last for five days with average use

so my battery has been draining really fast too, but my question is does the battery recalibration work? some people have said their battery drops even faster but is that only the first time?
PS. ive been on xtrrom for awhile now (like a month and a half) and it just started dropping. spare parts says android system is greater than the rest, if that helps

Yes, it works if you do it propely. Charge phone to 100%, boot into recovery, wipe battery stats, reboot phone. Use your phone as normal until the battery is fully discharged and it shuts the phone off. I sometimes try to turn it back on also just to make sure it is all the way dead. Plug your phone in to charge it, walk away, don't touch it until it is 100% charged. Turn your phone on and use it as normal. It sometimes will take a few times charging it to see a difference. If I missed anything or mistyped anything some one correct me please lol

Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?
turn off gps when not need
data when not needed
Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps
also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running
@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks
Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.
I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.
just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery
My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Gingerbread is Android v2.3. Froyo is v2.2.

@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.
i owe setcpu and screen off seting for my battery life
I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.
I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

Which ROM and Kernel for better battery life?

I'm looking for a ROM which can make my device hit at least 24 hours with light/moderate use. I know it's based on how the much the user interacts with the phone, signal strength, etc but there has to be a ROM which made your battery life amazing! I'm currently hitting about 12-14 hours with light to moderate use. I've seen people that use it the same amount and get nearly 2 days, how can I achieve this? I read somewhere that Pershoots kernel does well with extending battery life.
I'm currently on CM7 with the stock cm kernel.
Thanks for any helpful posts!
Okay so in my experience to get 'good" battery life with a g2 you need to turn off your push updates, stay off of data as much as possible, and only hook into wifi when you need it. Make sure your screen is on for no longer than 30 seconds, turn down your brightness, and set some profiles under setcpu to downclock you after you get to sub X battery life. Just make sure to increase the priority the lower your battery life goes.
The best and most consistent battery life figure I've gotten is 42-48 hr by generally not being a complete dickwad. If you flash a rom and have to download all your apps again it is going to suck you dry. I ran Cm6.1.1 with preshoots kernel for a goodly while and have pulled the same speed/battery life as I do on Virtuous with Advanced Kernel. It's taken a couple days for it to settle in but yeah, you're looking at 42ish with moderate net usage, full signal, and darn near constant texting.
Edit: Let me clarify. As your power goes down you should downclock in 5% increments. For every 5% less battery power you have, you need to increase the priority of that profile by 5%. Make a profile that is 100% priority but downclocks your cpu to 350ish max and 200ish min. Also something to keep in mind is that every piece of hardware is different. Some people can report fantastic life on the same kernel and OS. Just one of those weird machine god things.

I am running Desire_S_G2_Port_Sense2.1_Gingerbread_2.3.3 on my DZ and i am very happy with the battery life..
Thanks for the replies guys, looking forward to more!

I can get a day and a half with team villian sense ginger. The one before 3.0 best battery life i have seen yet. This is a 1.5days with constant OC no screen profiles or any kind of battery saving profiles. I would say im a slighty less then heavy user. Wifi always runs and i use gps for about an hour depending where im going. Now i normally charge her up every night but i have forgotten on ocasion and made it till i got home from work the next day.

+1 on villan rom, i set an off screen OC to 300MHZ and an on screen to 1.5Ghz, and i get 20+ hours out of it with mild data. wifi off unless im home and location always turned off unless i need it.
Might give that villian rom a try, is there a specific kernel I should use? Or should I just use the one that's already on the villian rom?
Sent from my HTC Vision using XDA App
just download from the current thread, the 1.5 version, it has an kernel that OC's to 1.5GHZ and works well.
i would download as is, and if you like, play with the kernel later on if you really want to.
Or if you like sense get sense ginger. Im not sure how you can get the older version but you could try the new one.

He is right, but lots of us has been through several ROMs and I can say that from the look of it all the ROMs use lots of battery life due to all the running processes. If you end up finding a ROM that supports your needs post it and let everyone know. Hope I helped

Best battery saving settings..?

Rom: unity 1.29
Kernal:unity V4
Radio: stock gingerbread
Set CPU: wake 1.1GHzmax - 245MHz min.. sleep 368max - 245min
So I recently came to the conclusion that it doesn't matter what Rom I use (sense or asop) that I always have horrible battery life.. I maybe get 4-6 hours of battery life with moderate to heavy use.. I was just wonder what is the best way to set up my phone to get the most out of my battery.. I've used the battery calibration app for all 3 of my batteries and nothing still get the same out of it.. yes I have 3 batteries but if they all die extremely fast whats the point? I've also used juice defender but that only helps if I don't use the phone..I've seen posts of people supposedly using the **** out of there phone and going a full 24 hours.. I just want to know what your settings are if it helps me at all.. oh I also know that T-Mobile recently had or still has 4g network problems but my battery drain has been going on forever ever since I got the phone when it came out.. thanks in advance for the help guys and girls

What i have been doing to counter the 4g problem is use 2g for non phone use times and 4g when i actually need to download or use mobile data. Ive also heard that auto brightness helps drain the battery faster than without. autosync settings can be important too. dont have it sync everything if you dont need it to. I get a long time on my battery and usually set it on the charger at night with 30-40% left.
edit: you didnt list the governer you are using. I use smartass or conservative for screen on or off and they help keep the clock speeds down if you arent doing something heavily dependant on phone speed like a game. Also when you say your radio is stock gingerbread, do you mean the newest leak one or stock that came with the phone? I have found the panache to give me the best reception which in turn saves the phone from draining itself from trying to find a signal.
Whoops New I forgot something..yeah my governors are smartass for when screen on and conservative when sleep.. when I say stock gingerbread radio I meant the link before the panache radio
I got my best battery life using faux123's AOSP roms, and his latest kernel has an undervolted version which makes it waste less battery without taking any toll on the performance. I don't particularly like the sense roms too much because I feel like they drain my battery power faster than aosp ones, and I don't even use all the features to their fullest extent.

I've heard the same thing as well actually. Personally I keep my brightness at minimum all the time(10%), but you could try 25% if that's too dim for you. 40%-60% is usually bright enough to see clearly on even the brightest days too, and I'm one of the unlucky people with a bad screen.
I'd also recommend downloading Muzikant's "AutomateIt" app and setting up some rules. I recommend setting rules that will brighten your display for apps that really need the light(Netflix, Camera, Gallery), and then dimming it back down once you close the applications. You can have it turn off your data and syncing and other such things under specific conditions and times as well, which can help your battery life immensely, and without you actively having to do anything.
And I guess you could try flashing a new radio as well. You might have to test out each one for a few days to notice the differences between them but eventually you'll find which one works best for your area and phone.
If the batteries you're using isn't the stock one, most likely those batteries will die out really quick. They don't hold their charge that well.
