[Q] EXTREMELY horrible battery life

I've read on many reviews (Gizmodo, Engadget, CNet, etc) that the battery on the DInc is not that great, but mine is incredibly... bad. Examples:
I browse the web (mostly mobile websites with not many images, flash etc) for ~20 mins and battery life decreases by 20%
I leave the phone ON overnight without charging and it's at 2% in the morning. When I went to sleep it was at 60%
I turn the phone OFF overnight without charging and it dies (I couldn't turn it on, had to charge for 15 mins even to turn on). When I went to sleep it was at 30%
I've also heard both that ATK is useless and that it's a gift from God for battery life. I'm running the Pro version killing every 30min and it's not helping that much (maybe 30 mins)
Is my battery defective, or are other users also experiencing this bad of battery life? My DInc is SLCD, running UberZ RC1.2 with stock battery.

Im guessing you havent had your incredible for more than five months right? Considering htc didnt start making them until the late summer. Anyways I do know that desire z ports often use up quite a bit of battery in their displays. However considering you left it on overnight and it was nearly dead I dont think it was that. Something you can try is going in the advanced menu on clockwork mod and erasing battery stats. This seems more like a defective battery though. New batteries can be bought for fairly cheap and if you do decide to get a new one you can get them for pretty cheap. Touchpro 2 batteries supposedly work with the incredible as well

Make sure you turn off GPS, WiFi, Bluetooth, etc. when not in use.

Yeah, I've had it for about a month. I will reply after erasing battery stats and trying it out. I'm not sure that I would use a Touch Pro 2 battery - seems like too much of a risk. However, I have seen Evo Batteries on Amazon that supposedly work with the Dinc. Do they?
If it helps, I use widget locker, with: extended controls, fancy widget, nexus revamped (with a lot of spawns on slow) and 3 sliders.

I have, I barely use BT or GPS so they're almost always off. I only turn GPS on when I'm charging and I'm using location based apps. 3G is off at home and Wifi is off on the road / at school and when I'm not using the phone.

What you might want to try doing is uninstalling widget locker and charging your phone all the way up. If after uninstalling widget locker the drain is still significant it may be the battery. And from what I read, the evo battery works with the incredible, it just makes the back cover fit a bit more tight.

OK, I've wiped battery stats, though it's only been a few mins so I can't tell yet. I'll reply in a couple of days. Also, can I just disable WidgetLocker instead of uninstalling it?
I also have a silicone case that hooks on the front edges, will an Evo Innocell (with back cover) mess with that?

I dont think an evo back cover would work for the incredible as they are not the same dimensions.
And btw touchpro 2 battery will work with the incredible

I just moved to an Incredible from my Droid 1 and the battery life is horrible compared... I got it as a replacement for having so many issues with my Droid but the battery life is almost unusable I'm running CM 6.1 and I wiped my battery stats, drained the battery then let it charge overnight powered off and I still get really bad life... I think a lot of it may have to do with the stock 1300mAh battery compared to the Droid having 1500mAh but I'm not sure... I'm considering the 3500mAh sedio battery but $70 bucks is a bit steep atm

Thanks for the great find, though I was thinking about maybe one of those seidio 3500's. Though since it's so cheap, I'll probably buy it

I've seen one on amazon for ~$25. Not seidio though. Reviews were meh.
I don't think its the 1300 mah vs 1500 mah. That's less than 20% (so like 10 hrs vs 12 hrs).

Didnt see the part about disabling widget locker, sorry.
Yes you probably can disable it just make sure it is definitely not running.

Don't run ATK. Android manages apps by itself. There's a whole lifehacker article on it.
Sounds like a run-away app.
Hmm, turn your screen off and let your phone sit for 5 mintues. Go into Settings > About Phone > Battery > Compare uptime vs awake. They should be AT LEAST 5 minutes apart.
If they're not, go to the market and install "Watchdog Task Manager" (<--this is NOT the same as ATK, again, lifehacker article on it) to monitor rouge apps.
Hope this helps!

My phone has been sitting and charging for ~2 hours, but up - awake = 5:12. Is it normal?
Great work, by the way.

There is no normal.
Up time is the elapsed time since you turned your phone on. (i.e. after the phone was completely off, not just screen off/sleep mode).
Awake time is suppose to only be the time your phone was actively being used (i.e. screen on).
So, Up time minus Awake time should equal the time your screen has been off, (i.e. asleep).
If Up time and Awake time are equal, and you've had the screen turned off (i.e. asleep) for part of that time, then you have some app that's staying active durning sleep mode.

I might reboot when I go to sleep tonight and do nothing on the phone, then check uptime vs awake when I wake up.

1300 Mah battery is not acceptable for a phone of this caliber. There are alternative options for battery's. I use setcpu to underclock the proc and I've seen a dramatic increase in battery life.

I've been using Setcpu as well, with 998 mhz while charging, 245 when screen off, 245-520 when hot or <20%, and 245-850 otherwise.
Agreed about the battery, HTC and VW probably want to force you to spend more on extended batteries.
Too bad, otherwise it'd be a perfect phone.

HTC usually seems to skimp on the battery. It really hurts their reviews but I suppose they can save costs and assume people can always buy an aftermarket battery. I don't agree with it but it's their business.
Anyway, that does sound like abnormally bad battery life, but I have a question - are you in a poor service area? If so, the radio might be working extra hard to acquire a signal. Even when I had my dumb phone Samsung alias (which had decent dumbphone battery life) I would experience complete battery drain if I left it in my poor coverage basement overnight.
Also, when you're browsing the web and such do you use wifi or 3g? I notice that when I continuously surf with 3g the phone starts to get warm, especially in mid-poor coverage areas. When the phone gets hot the battery gets hot, and when the battery gets hot it drains much much quicker. Of course, high power usage generates more heat so I'm inclined to believe our 3g radio consumes way more battery than our wifi radio.
Over the months I've combatted poor battery life by doing the following:
1. Purchase aftermarket batteries. I've fallen into HTC's trap. I bought an evo battery which can last me of 6-7 hours of wifi awake time and 4-5 hours of 3g awake time. I also purchased the extended 2150 battery from Verizon which I can get up to 10 hours of wifi surfing and 5-6 hours of 3g surfing. Back when I was on stock 1300 I would get 3-4 hours wifi surfing and 2-3 hours 3g surfing.
2. Install an undervolted kernel, if you're into that sorta thing. One of the main reasons I'm able to obtain the numbers above is due to my kernel which undervolts the processor. I use adrynalyne's experimental undervolted kernel and it works without a hitch. I use it in conjunction with setcpu so I can have a screen off profile which underclocks the processor to 128-384MHz while I'm not using it. The only caveat to using this kernel is you can only use the conservative CPU governor. This means lower clocked speeds will be preferred as the CPU actively scales itself, and will take longer to ramp up to the higher speeds. But we're talking about maximizing battery life so that isn't necessarily a bad thing.
3. Try to keep screen brightness down, minimize usage of other radios (Bluetooth, GPS). Sounds like you already do this though. Rogue apps have also been discussed but if awake time != uptime then that's usually not the case.
As also prevoiously mentioned, it is possible you have a defective battery and should go about getting a new one from them though I'm not sure how that process goes... someone here is bound to know though.

My signal is 3 to 4 bars on a 4 bar meter. Can you recommend a good undervolting Sense kernel?

Temp >50c 499/245
Screen off 245/245
Charge/full 998/245
Batt { 25 460/245
Batt [ 50 998/245
Batt{ 100 998/245
All are set to ondemand except charge is perfomance. Looking at this its nothing special but I do get a good charge from this setup

I definitely stand behind adrynalyne's experimental undervolted. You can find a link in the kernel thread on the android development section of this board. He makes a sense and AOSP version. I've tried some of the newer ones like Chad's but I love the longevity and stability of adrynalyne's too much to live with the switch. As aforementioned, if you decide to use setcpu, make sure to only use the conservative governer. Ondemand will cause it to freeze! Otherwise it's rock solid.

[Q] Poor battery life -- halp!

I recently got into rooting and flashing at the end of last year. This site has been a great resource for how to's and learning about the ins and outs of phone hacking.
Anyways, here's the background info: rooted using Unrevoked Forever, s-off, stayed with stock ROM and kernel only using SetCPU profiles. When I was on stock software, I had unbelievable battery life. I'm a light user (~10% awake time) and rarely beat on the battery -- light calling, email, texting, Facebook, random messing around etc. Anyways, when 3.70.651.1 came out, I knew that was my chance to flash my first ROM.
I flashed SprintLovers and got decent battery life, but nothing compared to when I was running the stock ROM. I then tried almost every variation of Netarchy's non-SBC's CFS 4.3.4 kernels -- more HAVS, less and no HAVS. No dice. I've tried with and without setCPU altogether, along with and without setCPU profiles but using the smartass and conservative governor. I always set the processor to 245-998 and never overclock.
I liked myn's Warm TwoPointTwo, so I recently tried that last week. Again, I'm getting okay battery life (~1.5 days) but with the usage I'm at I'm pretty sure I should be able to get 2 days easy. So I tried flashing Netarchy's 4.3.4 non-SBC CFS kernels with the same results. I've also tried with and without setCPU, along with and without setCPU profiles. Finally, I gave up and I'm currently using Netarchy's 4.2.1 cfs havs more smartass and using setCPU.
It's definitely not related to PRI 1.90 as I'm not getting the 100% partial wake time in Spare Parts, and I know the consensus is divided as to whether or not setCPU interferes with HAVS. I know all phones are different and ROMs and kernels interact differently on an individual basis, but I would really like to stick with myn's ROM and a good kernel to max my battery life. rather than go back to the stock ROM. Any suggestions on extending my battery life before I shamefully reflash back to stock software? I always do a full data/cache/dalvik before flashing a ROM, and wipe cache/dalvik before kernels.
myn's warm TwoPointTwo RLS5
netarchy-toastmod-4.2.1-cfs-bfq-havs-more-smartass
PRI and NV 1.90
setCPU 245-998 conservative
setCPU profiles:
temp >50*C = 245-499 powersave priority 100
screen off = 245-384 conservative priority 98
charging AC = 245-998 smartass priority 96
charging USB = 245-998 smartass priority 94

Try recalibrating the battery. Charge to 100% and leave it on the charger a little longer. Then turn the phone off and boot into recovery. In recovery wipe battery stats - in Amon Ra it's under the wipe menu. Boot back up & use the phone normally until the battery drains completely, without charging the phone at all. Some people say until the phone turns off on its own, but I'd try to avoid that. Just get it as low as you can. Then once it's dead, charge it fully without breaking the charge until it's completely full. You should see an increase in life after that. There's also an app in the market that clears your battery stats. I believe it's called "Battery Calibration", but I could be wrong about the name.
Since you don't use your phone much you'd be a good candidate for undervolting. If you don't want to undervolt while the phone is in use, just use a screen off profile only. Turning radios off while you don't have a signal or you aren't using them will make a huge difference as well. Let us know how it goes

I've heard people recommending a battery calibration after flashing a new ROM. My battery has seemed to be jumping down a few %ages and then stabilizing for long periods of time at a single level. Perhaps this is what I'm missing. I'll give it a try tonight when I recharge and see if that helps. I may try undervolting, but seeing as I got great usage on the stock ROM with the same CPU range I'd like to stick with 248-998. I always have a screen off profile though (as noted in my first post). I've also heard about people shutting off radios and such but I don't think I'd want to take it to that extreme -- maybe if I get desperate enough to eek out that much juice I'll give it a shot.
Bonus: to alleviate my problems at home since I have terrible reception and I know that eats the battery, Sprint is shipping me an Airave free of charge! In the process of trying to contact Sprint's CS (*2 on the dialer), the phone was force closing *1 and *3 work fine, as does normally dialing so I guess the problem is only limited to *2 (I even rebooted and am too lazy to reflash just because I can't speed dial a number I rarely call). Hopefully with your suggestion, I can get back to insane battery life

Don't know if this will help you out at all, but here's my setup...
myn's Warm TwoPointTwo (RLS5)
Net's toastmod-4.3.4-cfs-havs-more-sbc
Launcher Pro Plus
SetCPU:
Screen Off: 128 max, 128 min conservative
Battery<101%: 499 max, 128 min conservative
MinFreeManager:
Set to Aggressive
Twitter, Flikr, and assorted useless (to me anyway) apps frozen with Titanium Backup
Unplugged at 0700 and as of 2205, my Seidio extended 3500 battery is STILL at 74%
Average usage day, with tons of emails, and SMS/MMS messages. About 2 hours of web surfing and 3 hours of Pandora, but not a lot of phone calls today though. About 7 hours spent on WiFi, the rest on 3G (No reliable/stable 4G near me yet).
Background data off
Auto-sync off
Enable always-on mobile data off
I have noticed this is the best battery kernel I have tried out of all of Netarchy's (ymmv). I've had this kernel for 2 weeks, and getting 2 days out of it with HEAVY usage is no problem. I only lost 4% of the battery from 2300 last night to 0700 this morning with the phone sitting on my nightstand.
It seemed to not last as long at first until I wiped battery data and started from scratch. Always a good idea to wipe battery data when swapping ROM's and kernels I notice. Also read (here, of course) that new kernels have a "break in" time of a few charging cycles until they settle in.
Overall:
Completely satisfied with this setup. ROM is lightning fast, and battery is a non-issue with this kernel. Only ever so slightly laggy when opening Handcent or galleries (when I add pics and albums have to rebuild the thumbnails), but what the hell, it's only running 499mHz! Even fired up Avatar from my SD to check for stuttering, clipping, or audio lag. There were none!

OH!!!
Almost forgot!
I stumbled across this "trick" a while ago. Not sure if it ACTUALLY works, but at least to me it does.
It's called "Super Charging" your battery.
Charge with phone on until green light signifying charging is complete comes on
Disconnect charger
Shut off phone
Reconnect charger
Amber charging light will come
When amber changes to green, disconnect charger
When Green shuts off, reconnect charger.
Repeat process
I was bored this weekend, and did it for 4 hours continuously. Yeah, that is truly bored!
I had charged it so much that upon disconnecting the charger, waiting for the green light to go off, then reconnecting the charger, there was NO amber light. Straight to green. Tried it a few more times, with the same result.
Did it actually "supercharge" the battery? Who knows?
Did it take 3 1/2 days of use to break the 25% remaining mark? Yes it did!
So if you are bored, I mean CRAZY bored, what the hell! Give it a shot...

Thanks, but not willing to step into the realm of SBC kernels. However, I will try to go through a few charging cycles to see if my current NA kernel just needs to get broken in. I've also tried the charging method you stated above and while I did get good results, I'm unsure as to whether or not this is overcharging the phone so I decided not to do it again.
Anyways, I wiped batt stats last night after getting the full charge, so still on the drain and need to recharge to 100%; will report back after I go through a few cycles of charging.

Why not an SBC?? Because it fully charges your battery closer to 100% than a non-SBC?/
And don't buy into the hype of exploding batteries. That was handful of cases, that a) were all reported in the earliest days of SBC development, none since and were never fully attributed to the SBC kernel.
Also, you people that say drain til it dies, you DO realize that HTC STRONGLY recommends NOT doing that. According to HTC, you shouldn't recharge until you get below 50%, and no, I'm not gonna go look for the links, use the search feature.
I have a good method in my signature. Give it a try.

Can't argue with a battery that stays at 100% for 3+ hours then slowly drains versus unplugging it at 100%, blinking twice, and seeing 90% remaining...

Well, I'm no developer but if Netarchy says to beware in his latest kernel thread, even if for liability reasons, then that's good enough for me to stick with non-SBC until an SBC kernel is proven to be 100% safe. I think that's a perfectly valid justification to not use SBC for now.
I keep forgetting that we're not supposed to completely drain the battery. I guess I'll recharge when I hit 5 or 10%.
I'll take a look at your thread when I get a chance.

All threads (for the most part) say that, even ROM threads about not being liable if anything happens to your phone. Not even flashing a ROM is 100% safe but you do it anyway.
I've been using SBC since it was being tested the first time and I've never had one issue. No batteries have exploded, no chargers bursting into flames, and no phones have self-destructed.
If you want really good battery life, good performance, and want to try something other than Sense, CM7 and MIUI are really good ROMs. I would recommend Tiamat kernel (use 3.3.8 for now, 4.0.0 has some issues) and make sure to wipe batt stats and do a battery calibration. For good measure, you can try my BSM mod in my sig for even better battery life.

kings kernels are awesome!! im using one and is giving me 30 hrs!

Yes, all threads use the release of liability clause, but NA specifically states in his most recent thread that SBC could potentially cause problems.
Gosh, so much peer pressure! I'm not saying I won't ever go to SBC, just when I feel like it's a bit more stable and all the kinks are worked out. Kind of like you probably shouldn't buy the first model year of a car since the chances of running into glitches is much higher than if you waited a bit for the bumps to get smoothed out. If I'm being paranoid -- well, it's all in the interest of my $200+ phone. Regardless, I appreciate all the replies.
I've heard about MIUI here and there. I guess I've stuck with Sense since that's all I've ever known, but maybe I'll start branching out to AOSP and MIUI. Does CM7 have full functionality now on the EVO?
I'm on my first recharge since wiping stats and it's the fastest recharge I've ever seen. Maybe I do need to just break the kernel in?

[Q] Horrible EVO 4G Battery Life no matter WHAT I do!

I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.

Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom

Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/

You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.

Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/

Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

I had an Evo, loved it,but the battery was trash,even when I bought my 3500 mah battery, the juice in it wouldn't last a whole day,sorry man,there's just no hope for that phone,without undervolting properly

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.

[Q] Best Battery Life..

I know it's been asked before a million time, but I don't have an Inc my daughter does. she has been running cm7 for the longest time. but it's gotten really bad as time had gone on. I have seen the list of ROM and it is huge, all I care about is battery.. dont matter is it AOSP, sense, senseless etc.
Can you please suggest the rom with the best battery like.
Thanks

Running MIUI with incredikernel with smartass 2 enabled and 128 min, I can go 2 full days with medium use till I need to charge again. But what works for me might not be the same for you or anyone else, that all depends on what all you have running/syncing in the background, how many times it syncs, network data, etc.

If she is using the same stock battery that came from the phone, it's likely that now it can only hold 60-80% of the original charge- depending on her use.
Maybe consider dropping a few bucks on a 1900mah battery (fits in stock casing).
-- -- -- -- --
I would stick with CM7, and make sure you're using the incredikernel. Try flashing the predefined "undervolt" file. If she has reboots, then just revert it and no worries.

even i also have found that CM7 is the best for battery life

Going to have to +1 that. CM7 definitely has had the best battery life on my phone, and I've flashed a ton of ROMs. I'm also running Incredikernel with smartassv2, which I think helps a lot.

Recent Anthem 3.0 can hold amazing charges, the OP had a 54 hour charge, someone also had a 20+ charge.
I'm guessing she uses it alot, Cm7 for me has been nothing but bad battery. Drains within an hour of medium use.
My suggestion is give the Anthem 3.0 a try and see how you and her like it.
Sent from my HTC Droid Incredible using Tapatalk

Try Inc-Deck 1.3. It's an offshoot of CM7.1 and it works great with incredikernel 3/21 ICS. Set the govenor to interactivex, the max frequency to 883, the screen brightness to 20%, the screen timeout to 15 seconds and cross your fingers that you live in an area with strong signal.
I get anywhere from 16-30 hours with that combo depending on how much data I use.
If your daughter does not use much data switch it off... an instant 3-6 hours battery boost.

I have to agree with this
Sent from my DrOiD InCrEdIbLe because its CoLd

Anecdotally, I have found battery life improves with two things: leaving the screen off as much as possible (screen always drags battery life) and using wifi when it's available (the comment on data usage is true, it's a drain).
Also, getting a second battery is always a good idea, adds to the versatility of your smart phone experience.

I've found that the older gingerbread and sense roms have better battery life.
I would look into Nils' Business Gingersense ROM, and PureMotive's Anthem ROM (http://forum.xda-developers.com/showthread.php?t=1530687)
I prefer Anthem, and if you follow the instructions on his post (using gingertiny kernel, setting CPU speed) you can achieve excellent battery life.
I personally used Anthem with Tiny's kernel and got about 48 hours with regular use.

For those with battery issues.

Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.

If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.

I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%

Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB

I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

I got over 30 hours last weekend with light use, but the next day, my battery would drain 5 to 10 percent per hour with no use. I have all the utilities to track what's happening, but cannot find a definitive cause. Poor reception seems to be a factor, but not the whole story.
EDIT: I just installed GSam. Thanks for the tip!

Try the Re-Calked FI03 and tell me ICS sucks....this things is as good if not better than Calkulins v3 GB rom....the ONLY other rom i have ever liked.... :good:

Maybe you should've posted this after receiving and using your new battery. My phone had horrible battery life after a while on ICS but it turned out that it was in fact the battery and not ICS. Got a new battery and it is back to 18 hours a day (on ICS)

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...
https://play.google.com/store/apps/...av_result#?t=W251bGwsMSwxLDMsImNjYzcxLmJtdyJd
Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.
