[Q] AARRGGH!....Battery on my Evo stinks! - EVO 4G Q&A, Help & Troubleshooting

Configuring this thing for good battery life is exhausting. Before root I had done most things listed in this thread : http://www.xda-developers.com/android/tweaks-for-superb-battery-life-in-evo/ and finally achieved pretty good battery life.
After root, I have never been able to achieve this even though the bloatware isnt running, have various tweaks on there for performance, and so on.
Have tried Fresh Rom with stock and Kings #11 and liked it but had terrible battery life. Tried Myn's 2.2 with stock, Kings #11, and Netarchy and battery was not much better. Now running AVA9 (no flashed kernel) and battery is no better. Have tried running setCPU on all these setups and does not help.
Any suggestions? Seems someone will say this rom/kernel combo works for them and another person will say it sucks, don't use it.
I couldn't stick with Myn's because there were too many bugs/errors. If my best bet is to go back to all HTC stock rom w/root then so be it.
.....and yes, I have read through the numerous amount of threads on this topic but no clear combination has been highlighted that I have seen. I use my phone for business primarily so it needs to last me as long as possible. The thought of increasing my phone size with an extended battery is not appealing to me.

I have stock rooted 3.29. I initially did the plug-unplug trick when I got the phone. Then, I turned off always on data, and set email, google accounts, and Sense weather widget to update once an hour. Phone behaves the same as when data is always on, so I don't even notice 3G off when the screen is off.
I get 8 - 10 hours under very heavy use (constant fiddling, email, games, internet, calls, etc),
10 - 15 hours moderate (surfing, ebooks, email, internet),
and easily 18+ with light use (email, occasional light surfing, occasional call)

I have everything the same as before root so with the bloatware and some other things not running would think it would last longer than stock......not!
@greyopaque...what was the reasoning for using stock rom instead of custom? Battery life or just never tried any of the others? Would like to know if your battery life is better with just the stock over others.

Ditto....I am a heavy user and leave everything running that I need. I use the phone for what it was made for. After trying/not trying all different types of roms/battery tweaks/advanced task killers/battery monitors etc., I decided to buy another original red 1500 battery as I don't like the extended battery look either. So, until they come with better battery technology....I guess that would be the career to go into and make some money ;0).....we are stuck with the best phone ever...yet....with a battery life that sucks for those of us that put the phone to the test....have a great day!

Yep...only problem is having to shut the phone off, change battery, then power back on. All the while, missing whatever phone calls come in.
***My point of the thread really isn't the terrible stock battery but the fact that the pre-rooted setup lasted so much longer than the rooted w/custom rom. Why??
I would think the battery life would get better without all the bloatware and other worthless services running all the time.

Once again.. you need to check your apps. Most likely there's something causing a drain.. Try updating to the newest rooted stock roms (3.30). The new kernel is definitely an improvement.
As an aside.. what bugs did you have with myn's 2.2 rls2? I ran it, and it was fine. Now on rls3 beta and amazing rom with great battery (3.30 base).

To be honest, I've never tried anything else. I really like the stock Sense experience... and since this is a work phone, I need it to work without glitches.

Well....hopefully I can hear from some peeps that have used a good amount of custom roms/kernels, as well as the stock one and see what they think.
Cmon guys....let me know!
@eyeballer1......Myn's was just acting weird and I kept getting a "com.htc.bgp" force close that I couldn't fix. Also, I have tried the newest stock rom but it is just so darn plain jane didn't keep it on long enough to test it. As for apps, I have basically the same apps on my phone that I had before root (except for specific root apps such as rom manager, titanium, etc).

Sadly they won't.. That is battery technology.. This world is pretty much stuck where its at and will probably stay there.. Its the one thing that is not progressing that much.. Even from the 50's
That said.. the thicker battery is the way to go.. Only you will know its thicker, and trust me.. ITS NOT THAT BAD! Believe it or not you get used to it.. If its for business, well then a thicker battery should not bother you at all, use it during the day and maybe at night switch back to the smaller one.. You know, for the dates and ****
The thicker battery will be a life savior.. All these battery tricks and tips help, but nothing is going to be mind blowing.. The fact is, this phone is extremely advanced and requires a lot of power.. I just except the fact that I need to be close to a power charger at most times..

I might go ahead and try Myn's new beta with 3.30 and see what happens. Looks as though I need to look deep into what is actually using my battery. I have always used K-9 for email and have heard it sucks up battery, but it only uses about 2% on mine and is the best email app I have ever found.
@fastfed......I'll have to ask my wife if I can go on a date sometime.

what helped me the most was wiping battery stats correctly (as per cyanogen wiki, but applies to all roms).
Charge to full, turn off, wipe battery stats. Turn back on, wait till everythings loaded, unplug. Use as normal until battery dies (do not charge at all until battery dies). Recharge fully in one go (meaning do not unplug while charging until full). Use and charge as normal.
This should be done whenever flashing new rom.

I also use k9 for mail. As I use Hotmail not Gmail.. is it really that bad? Anything else out there ?

The biggest positive jump I have seen in regards to battery life was going from Cm6 to 3.29 ruu stock, then I ur3 to root.
I'm still sceptical that the 3.30 zip update gave any improvement to battery life as I have seen others report. In fact, I almost wonder if I somehow have less battery life now, but it could be in my head. It's almost impossible to approach this issue scientifically since I use this evo all day.

Try bakedsnack 1.8, its the best battery life I've seen on a rom w/o having to make all these stupid tweeks and disabling features on ur phone.

I'm gettin great battery life using vaelpak 2.3 with the stock htc kernel. I imagine most of the custom kernels around are based off of older kernels and while they may have higher "performance" ratings though I have hardly been able to tell a difference between kings 11 or baked speed and battery, I think the newer stock kernel is your best choice no set cpu to worry about, its just simple. I'm personally gettin about 14 hours with almost constant music playing to bluetooth headset, a bunch of browsing, and occasional use of google navigation which is a big battery eater. With just phone and text use after 21 hours I was at 52% yesterday.

ok so i have literally flashed every major rom / kernel and a comination of each. I have found that with minor tweaking most sense based roms get close to the same battery life. some people will argue that this or that rom is best but I would challenge others to truely preform a test on them and i bet they would be suprised.
k-9 is only a battery hog if you have it constantly polling for new emails if you have it set up to scan constantly then it will take a reasonable about of battery life but nothing more then most other email apps with the same settings.
have you tried as was lsited above and recalibrating your battery? I am assuming you are a pretty heavy user from the sound of things. How long where you getting pre root and how long are you now getting rooted? do you have titanium back up set up on a schedule? If so that can cause major battery drain as it sometimes keeps your phone awake.
All in all with the information you provided no one can actually tell you what is wrong. there are to many variabes and everything we say is a shot in the dark hoping to hit common problems.
my best recomendation configure your battery stats as listed above, if you havent tried use the HTC trick (chrage battery for 8 hours turn off phone charge for 1 hour turn on phone unplug it or 2 minutes then turn it off and charge for another hour.)
Anytime you wipe data you wipe your batary stats and it can drasitally impact your phones "battery life".

At this point I'm not so sure my battery or charging device on the phone isn't defective. But, only time will tell.
Currently I am running the newest, non-beta Myn TwoPointTwo and Netarchy 4.2 non-havs. I also ran this procedure (which fachadick already suggested):
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
I'm still on step 3. Will report back after a few days.
I had never heard of doing this when switching roms so hopefully it will help since I have swapped out a good amount lately.
Does anyone know where to get the newest HTC flashable kernel based on the new 3.30 release? All I have found is the rom package.

[Q] HTC EVO -- Best Battery life ROM???

Can anyone tell me which ROM (STABLE) provides the best battery life on HTC EVO???
Thanks!
I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.

I know that the latest kernels off the latest build have been killing my battery, it's horrible for my EVO.
But you really have to try different rom/kernel/PRI/radio combinations to find the best battery life for your Evo. I wish there was a preset rating system for each rom though, just to see how things work for everyone else(i.e. battery life, quadrant scores, force close problems, etc.)...but there really are a lot of variables, so I don't think that may ever happen.
Yeah I agree there isn't a clear cut winner. Everyone uses their phone different so it will differ for everyone.
Totally agree to give it a few full charges... I suggest when you get a new rom and/or kernel installed to reset the battery stats (can be done in recovery) then use it till it dies then charge to full before turning it back on.
Personally, I've been using Fresh 3.3 w/ the Kings #6 kernel and not only has the phone been screamin' fast the battery has been good. I'm only on my 2nd charge up though so I still have one or two to go before everything smooths out.

I'm using the latest Fresh and I just plugged my phone in at 15% battery after 37 hours. I'm pretty happy with that.
Fresh Rom always gave me good battery.. I'm just using the rooted stock OTA and am getting great battery life.

I think it would be a great idea for this kind of stuff to happen. Some aggregated source where everyone can submit their information using various roms, kernels, etc. Whether it be information regarding Quadrant scores, linpacks or battery life. On computer hardware forums they generally have a section dedicated to OCing records with charts listing someones entire setup while attaining the clock speeds. I don't see why a similar implementation can not be done here.

i use Fresh's Rom made my battery life live avg abt 15 hours
Over 40 kernels were tested and benchmarked in 7 different ways, and the results are posted here.
Should tell you everything you want to know, without bringing roms into the picture (since battery life is most affected by the kernel used, not the rom)
edit - looks like I'm a bit late withthat link - I see the thread for that site was already posted above. It's a great resource.
Fresh 3.2, hands down best battery life for me. 3.3 was pretty bad, as was myn's release....which sucks, because myn's rom is otherwise awesome.
I am using Fresh 3.3.0.1 with a baked kernel that is able to over clock. I then have SetCPU installed with profiles for different states of the phone. If my screen is off I have the cpu set to a max of 500MHz to save battery if there are any processes running in the background. I then have my cpu set to 1119MHz when the phone is plugged in or at 100% with the screen on just because I like a snappy phone. Then when the battery drops below 50% I have it return to stock speeds.
I use my phone heavily for things like subsonic, QIK, FB, Calendar, wireless tether, and of course since unlimited data, calling to any cell, and texting I am on it a lot keeping in touch with friends. I also use the sprint nav at least twice a week.
Results will vary from user to user but so far the phone has been on 7 hours and after some moderate use it's only down to around 75% on the battery.
Again this is how I MYSELF use my phone with this rom and kernel this may not be how you use your phone and you may see different results.
What I have done is searched roms and installed them in total I have used 4 different roms. Baked, Cyanogen, Fresh, and Virus. After installing each rom and setting up my phone I made a nand backup of each so I can flash between them as needed to test. I have found out of all of these roms Fresh 3.3.0.1 with a kernel from the baked roms has worked the best for MY daily use.

[Q] Gf's battery life (need suggestions)

I've done everything I know to do to help with her battery life. She has a hardware 0003 Evo, the exact same as mine. Both of us have Sprint Lovers ROM with PRI 1.77. I have Netarchy 4.3.4, she has 4.2.2 because 4.3.4 didn't work well on hers. The only real difference between our setups is mine. I have Titanium Backup with most of the useless apps frozen and UltimateJuice with the latest JuiceDefender Beta. I also use LauncherPro.
I've noticed that her device pulls high mA's when discharging. I believe I saw one over 1100mA earlier while looking at something on her phone.
I realize that my setup may be a bit more battery efficient than hers, but her drain should not be as high. She literally has to plug up several times a day, when I can go 2 days on a charge.
So does anyone have any suggestions? I really don't want to have to swap out her phone.
you should try nets 4.3.2 cfs havs less, or the no havs those are very stable and great with battery life, before you flash fill battery wipe caches and battery stats, flash kernel
Try installing the 4.3.4 kernel again but play around with the versions. Try a less-havs if more-havs doesnt play well. Maybe even no-havs. Try installing juice defender on hers also and see how well it plays out.
Update her PRI. I run the most up to date pri and don't have any battery problems. It's probably that I can almost guarantee it. Some phones work better with different set ups then others. To update you can use caulkins flashable update zip. Its in the dev section in the first couple pages if you don't feel like searching. Just be careful when flashing.
get a 3500 battery, or maybe her battery is defective. You're a sprint service technician? come on now

Well, I'm not versed on sense kernels, but perhaps try a less aggressive havs kernel on hers. Does he keep her 3G on all the time, cuz that'll be a battery drainer.
What she could do is change roms, or if she's willing to, try out AOSP.
Calibrate the battery.
3500!! is the answer. You can't do anything with the stock battery. Does she give it a full charge often? My girlfriend only charges were phone a few hours each night and complaines that it dies often... and thats with the 3500... Even if the light is gree and it shows 100% done, its not really done. Let that thing charge for 8 hours straight. Google Bump Charging... that helps too.
In addition to all things suggested here, never underestimate the power of turning off auto-sync and background data. I keep background data off all day and then turn it on for five minutes or so every night to check gmail, etc. If your gf is anything like the girls I mess with then she's probably just killing her battery by updating her Facebook status twice an hour and tweeting every time her cat farts. Not much you can do to help if that's the case...
Social mongers pay for their insolence in battery life. For the rest of is, there's the background data toggle

Actually, she doesn't, so I'll probably end up doing that. I tried her on CM7 but she didn't like it, gave her more problems than usefulness.
If she's not a big background data user then you should definitely toggle it off. With comparable usage, I typically get twice as much life-per-charge with background toggled off than on regardless of what ROM or kernel I'm running. It's the biggest little thing you can do.

[Q] Synergy Battery life and App issues

Hey folks!
I have the EVO 004 Supersonic. I love flashing my Android, and do it constantly. I am having issues with Synergy RC1 that just went live. My battery is draining fast, and I mean in an hour maybe two, I have to charge it. That is just being on idle, not being used. Drains much faster if I use it. I flashed back to my original image (stock) and the battery lasts longer. So I flashed Mik, and it lasted longer and I flashed CyanogenMod and that sucker lasted longer, but I LOVE the way Syngery looks and flows. But I cannot get the battery to last longer. So I thought maybe apps were running that are not supposed to, so I use my favorite app killer and the apps keep popping up, they are driving me nuts. Why the hell are they restarting? I want them stopped and NOT to reactivate. Is this an issue with anyone else, because I really do not want to get rid of this ROM. Also, yes, I cleared the Battery stats as well. Still fast drain.
Oh, one more thing, I cannot OVERCLOCK the damn thing either. So, those are my issues, cannot get apps to stay shut off (force close even), Battery is dying super fast and cannot get it to stay charged longer than two ours. Oh, and I already checked my battery with Sprint, battery is good, and they even gave me a SECOND one, and it still drains fast. Please advise.
Thanks for listening folks, and I appreciate any help. I love this site and has helped me NUMEROUS times, but I finally had post my own specific issue as I have never dealt with this before nor found anything that can help.

jeez...dead in 2 hours...and being idle?! that sux. i was running Synergy for a while and didnt have THAT bad of battery life (i maybe had 7-8 hrs before it needed to be charged again)
and of course you cant overclock yet...the kernel doesnt support it! it's still the stock kernel that came with the OTA...HTC still hasn't released the source code for the kernel so no custom "gingersense" kernels for us just yet (i.e. no HAVS, sbc, overclocking, etc.)
try some of the battery saving tips that Myn links to in the 2nd post of the Synergy thread...maybe that will help
question for you: why are you using an app/task killer!?!?!?! Android has one built in already [MENU >> SETTINGS >> APPLICATIONS >> RUNNING SERVICES (or MANAGE APPLICATIONS)] that could also be a reason your battery life is crappy (i really hate task killers so that last line might be biased lol but seriously...android does have it built it)

First, Synergy runs on HTCs stock kernel, they havent released the source code for the kernel yet, so there are no custom kernels for any evo 2.3 rom, so you cant overclock, or get the awesome battery life we usually get from custom kernels.
Now the battery draining is usually the radios. Right now I have wakelock on my phone running synergy, but I dont wanna mess with my radios, you would have to try different radio/pri combos until you find the right combo.

I use task killers because I can kill all tasks at once instead of individually. I would like to be able to close apps I am not using as well. But they keep popping up. I know now the overclock does not work with gingerbread, but man, I got a lot of misinformation.
I appreciate your help, I will try the battery saving tips, but if it is about letting the phone die, erasing battery logs and then charging it and then making the green light stay on when first plugged in and other stuff like that, I have tried it to no avail. I just flashed another ROM and the battery is FINE! It is so damn frustrating. I see others with great battery life. I just cannot get mine to do it.

Well, you guys probably will not believe this, but I got my battery to last a looooong time! I was messing with my battery options and decided to turn OFF the battery saving option it gives (enable power saver). I rebooted the phone charged it fully and then took it off the charger, BAM! Being FULLY charged it went down one percent after being on for 40 minutes. That is much better than I was getting on my stock and other roms. I just love this dang rom. Now, if I could only overclock the darn thing. So I have had the EVO on for 2 hours and 10mins and the battery says 97%, sweet. Anywho, battery issue is solved, loved it. Has this been mentioned before? Turning off the battery saver to save on battery? LOL. It probably has and I must have been to frustrated to absorb that info. Thanks for your help!
Battery saver...
I, too, was having draining issues on my Synergy-ROMed Evo. I could WATCH the battery drain. But I turned off the "battery saver" in power prefs and it's HOLDING STEADY! I'll report back if this doesn't turn out to be the cure I was hoping for, but it's definitely worth a try.
Now if I could just get this GPS to stop rebooting my phone...

I am looking for some help in choosing a new ROM for my HTC desire, the main thing i want to see is the new Gingerbread OS 2.3 and the improvements it brings (battery life), but sadly it has not been officially released to the Desire platform.
EDIT :
Okay now Im on CM7, probably gonna try oxygen later, but till now CM7 suits all my needs and the battery seems good (20 to 26 hours heavy usage) but im running into a small problem.
at 9% the battery dies and phone turns off, battery and phone seem somehow out of sync so 9% means 2% or something, how can i fix this and make it turn off at 2% ?
If it's battery life you're interested in, Oxygen is pretty awesome, but it's AOSP so doesn't have any Sense stuff (widgets, messaging app, camera etc) - there's stuff on the market that provides equivalents/better versions though.
I've just flashed a sense ROM a couple of days ago after coming from Oxygen and I'm missing Oxygen so much that I'll be going back to it tonight It's very fast and stable.
But if you want to stay with Sense, this ROM is as close to stock Gingerbread (with Sense) as you'll get http://forum.xda-developers.com/showthread.php?t=1124810
People have been getting good battery life with that but I've not had too much luck getting great results. It's very smooth though
EDIT: CyanogenMod 7 I can't tell you too much about as I've only briefly flashed it. I remember it didn't feel as "clean" as oxygen but it had a huge amount of customisation potential (though saying that, the latest Oxygen build has almost as much, with the ThemeChooser). Also I don't think CM7's battery life is as good as Oxygen's.
What I'd do if I were you: Flash the CM7r2 HBOOT from http://alpharev.nl/ then flash Oxygen/CM7/SGBS depending on what you want to try first - all 3 work on that HBOOT so if you don't like one you can just flash another quite easily.
Make sure you know what you're doing flashing HBOOT though as there's a risk of bricking associated with it. So just read up first.

Thanks.
I decided to try CM7 7.0.3 for a while and i like it. Alot of customization and some neat features, but the downside is that i dont feel like the Battery consumption has changed at all, its still as i have had my 2.2 froyo stock i think.
I did a small measurment of battery consumtion please tell me if i should be getting these results:
First
-Phone with CM7 rom Charged at 96%
(turned on wifi for like 10minutes, did around 6 phone calls, 1hour looking around settings, animated wallpaper activated for an hour)
After exactly 6hours the battery went down to 76%
So in 6hours the battery decreased 20%
Is this a good result? Will I be getting better battery life in the Oxygen rom ? If so i will definitely switch to Oxygen.
Well that's not exactly bad. I'm currently on 42% after 20 hours 30 minutes with WiFi on syncing emails every hour, a bit of browsing, over an hour of gaming (trial xtreme), some texting, about 20 minutes of calls and some music playing too. Idle it probably uses less than 1% per hour. I'm on the latest oxygen.
I'm really happy with this battery life
I'd recommend downloading battery calibration from the market to get the most from your battery.
Redux is a good ASOP ROM with good battery life - its quite stripped down.
For a sense ROM - I like LeeDroid.

Or completely ruin it. Battery calibration is to be used only if your battery percentage is out of sync with real mV status, so your phone ends up dead at say, 10%. It is not to be used to decrease battery consumption, which is not going to happen. Ever.
To OP, it boils down to your preference. I couldn't care less for ota updates, but if you do, flash ruu, or maybe even rooted stock would work, I'm not sure about that though. As for battery consumption, you had 1 hour screen on, some calls and texts. I'd call that fair.

Yeah you're right. I meant battery monitor widget. It was late at night, forgive me
Battery monitor widget gives you a good idea of what your drain can be attributed to so is a very handy thing to have on your phone. Battery calibration (as the poster above mentioned) is to line up the amounts your phone reports with the true amounts and should only be used if you're getting strange shutdown occurrences etc. Sorry about that
Some people use juice defender too but I don't really like it tbh.
Yeah, those placebo apps are the best
Juice defender, setcpu, task killers, memory menagers etc share the same place in the Hall of sillyness.

To the OP (not erklat)
If you flash a carrier RUU you're all set for ota UPDATES.
If you de-branded the phone yourself, you can still get ota updates, just make sure your goldcard is installed prior to installing the update. If you update without a goldcard you will lose your data connection
If you have a rooted stoc, same as erklat's opinion, I think it should work but I have never tested this myself.

No i read this method and many users are reporting battery damage. I dont want to do this. My battery on regular use (calls, wifi, games,browsing) lasts 26 hours max and on idle it could last like 40 hours or more maybe.
Its just that the phone is turning off at 9% battery.
I used the Battery calibration app suggested before by cgmorris89 but then erklat said that it would ruin things.
What can i do to make my phone turn off at 2% ?
Oxygen every day!
Try MIUI.us!
Miui is using cyanogenmod kernel and base over which it gives great launcher and best default sms and phone apps.
Firewall and white/black list call blockers are included also.
If you can live with english locale, of course.

Thank you guys, yes i will try Oxygen and MIUI later on, but now im testing with CM7 and i have this battery percentage problem. If anyone has a solution to this, will be very much appreciated.
And another thing, should i update my Radio ? i have 4.08.00 something, is it safe to do so or might i brick my phone ?

Best Rom Out Currently (Battery life)

Download and install the unamed from via the development section and definitely donate if you can. Unbelievable battery life and quadrant reaches 3600. To maintain great battery, hopefully you have wifi, turn off your 3g and 4g and don't have email, contacts and pic uploading active in google sync.

In other words, if you don't actually USE your smartphone as a smartphone, you will get fantastic battery life?
I'm just being a smartass... I like Unamed! Although with ALL the custom ROM's so far, I seem to get better battery life on rooted stock kernels than any of the modified ones!

i feel you but if you aren't a frequent email recipient or know you're not going to have notifications on social networking a bunch, adjust your settings and data to have efficient battery. even with those things on, i get like 16 hours which a more than enough. having your radio (cell network) on when you have wifi actually uses more battery so just shut it off and use wifi which is less of a data consumption monster (battery drainer)
lol @ not using it like a smart phone. smarty
I have all my syncs active, 2 e-mails, 3g all the time and easilly get 24yr use with 3-4hrs screen on with Caulkins. Why would i criple my smart phone by dissabling syncing contacts and such to get 22hr use? If i loose my phone it wont have it all backed up. I get 48hr easily with 2-3hrs screen on time......
I am using Blazer EK02, and the battery life os 24+ hrs consistently with normal use on default rom settings, and WiFi/3g/GPS/sound/sync (3 emails + 1 Exchange email), and lots of background apps running intermittently (TB, auto updates, etc) with maybe 2 hrs active screen time. This is 1.5x longer than anything else I have run under same usage. I do use low vibrate and no tactile sound feedback.
I will be trying out Blazer, Caulk and Unnamed once they are final and report back. The only true test is same person, same phone, same use, same bat calib process anyway.

After spending the weekend trying various ROM's, I've determined that stock (rooted) EG30 gives me the best battery life. All the EK02 and EL13 ROM's drain a lot faster.
With my normal use on EG30, I have about 75% at the end of my work day. I have under 60% on the updated ROM's.

I didn't say you should do anything. I share what I've done to get what I have. Not syncing contacts all day doesn't cause you to lose them... your contacts are always sunc via Google.. Gmail. You only need to sync once and then manually sync it if you add a contact so It saves to you Google account.

Bro the totally stock is the best battery life for me as well. I just like the extra snappyness of a good optimized rom like Caulkins. Stock i got 5-6hr screen on time consistently. But sacrifising 1-2hr of screen on time for a rom thats all Modded up and i have flashed themes onto and can hot apot from and all that other stuff if so worth it in my eyes. But ya, totally stock cant be beat in my book as far as battery life ia concerned

I hear ya, i just like to have it auto do it all so i dont FORGET to synce contacts or something like that. Lets say im drunk at a bar and get a nice Dime Pieces number and my drunk ass drops my phone in the toilet once i get home. I want it to sync so i can still have cutties # haha. But ya i know what your talking about OP. I just dont go that rout cauae. Im forgetfull and wont synce things for a few days and woyld wonder why i havent gotte. E-mail forgetting i dissabled it. Besides some times you get those ones you want to respond to qyick. Like some one buying the 25" monitor im trying to sell on Craigs list fir half price thats brand new. Oh yes feel free to hit me up if you want a sick monitor
I think blazer 2.0 on eg30 modem gave me the best battery life so far. El13 modem and blazer 3.1 is not as good as my previous setup I mentioned.

I hear ya. I love the 1x mod in particular, but losing 20-30% of my battery life (at least the way I use my phone) between charges isn't worth it.
Using hotspot is nice, but Wireless Tether works just fine for me, too.
I've experimented with few roms during the past couple of weeks and so far. While they all gave great standby time, Blazer 2.0 gave me the best battery life as far as screen-on-time. (3 hours 50 minutes of screen on time)

Phantom's Blazer 3.1 version. I've always had great battery on it, but on the latest one it's even better. I have everything syncing because I do want to use my phone and not have it be paper weight.
Nice, I've been wanting to upgrade to 3.1, but I am waiting for Phantom Hacker to come out with the ICS theme for it. In the meantime, I'm giving UnNamed v2.0.1 a test drive...can't speak for battery life yet but man its fast and the ICS transition animations looks real nice.
