I am a bit concerned about the battery life of the upcoming htc. The first reviews I have read about it on german blogs speak from 12 to 15 hours battery life under medium to heavy usage. Even though, one needs to remain cautious with these numbers as the software is not finalized, I wouldn't expect these to double when final.
The Incredible S has a quite satisfying battery life according to users experience. But the Sensation has a bigger screen, higher resolution, a full load of 3D effects and almost the same battery. I fear the battery life will be insufficient in that case, even though dual core is supposed to consume a little less.
Samsung has built a slightly bigger battery on his GSII and people seem to experience a very good battery life. But Amoled doesn't drain the battery when black is displayed and the whole UI has been designed in black for this purpose. So the Sensation will probably not be able to achieve such an autonomy.
Hopefully it will still go through the day under heavy usage. Otherwise I might gonna settle for incredible s instead.
Has anyone read other numbers somewhere?

This is how I see it. Multi-core cpu's theoretically are more power efficient. You spread work over both cores, if software is optimized, to allow for less "strain" on the cpu. From what I can tell they are "optimizing" their Sense UI to run on both cores which efficiently manages the amount of power is being used. This now gives you less power draw hence power is saved. The battery isn't as big as some devices, but in my honest opinion I believe you will get a little more than 12-15 but probably won't get up to double that. This is all based off of my own conclusions after reading several articles. I may be wrong and if you need to correct me feel free. =) All I will say is you probably won't have to worry about battery issues.
I currently own and use a HTC Mozart on WP7.5 but since I got myself a 3D monitor and soon a 3DTV I have got interested in changing over to the LG Optimus 3D apart from the obvious software difference (please note I have previously had HTC Desire/Desire HD/Legend etc so I am adapt to Android) I have to look towards the Optimus as no-one near me has the EVO 3D for sale

Good luck 3D is the only good part about it. If you're interested i can sell you mine with 2 xtra batteries. One 3500mAMP with extra big back plate.
Yeah i would honestly advise against getting one. Ive had it with running out of ram every few hours.

Why do people complain about battery life surely it depends on usage?
When I had my Desire HD others were getting between 15-24 hours whereas after getting optimal charges I was getting between 24-36 hours. I am not a 'heavy' user but it does usually take me a good week or 2 to get to an optimal charge.
Compared to the DHD
Battery:
Idle battery life is similar (around 6-15% a night on 3G)
Music playback battery usage is significantly lower. (i get around 20 minutes to the percent on O3D, 4-8 on the DHD)
Screen on battery life (any brightness) is lower than screen on Max brightness on the desire hd - I get at least 4 hours of continuous screen on with 100% brightness on the Andrev 6.31 rom, whereas i can barely get 4 hours screen on time on any O3D ROM @ minimum brightness.
Screen on + Gaming battery life is significantly lower. I sometimes don't even get 1 minute out of 1% on the O3D.
Other:
O3D slightly faster
Sense is awesome, LG launcher is horribly fail and laggy.
The stock LG lockscreen takes around 1-2 seconds to appear after opening the screen whilst DHD is instant. This isn't due to the phone itself, as when PlayerPro replaces the lockscreen, starting up in instantaneous.
The DHD camera is much easier to use. LG camera takes 3 seconds to start, and another 3 to take a photo. Quality wise though, LG is similar, even though DHD's is 8mp.

Since you are mainly interested on the 3D features, the on-screen 3D experience of the Optimus 3D is way ahead of the EVO 3D; there is absolutely no comparison between those too. As for playing the O3D videos on my 3DTV the quality (up to 720p) and the 3D effects are very good.
Regarding the rest of the O3D features pros and cons, you could stay with the Froyo or upgrade to GB which has increased battery life but it suffers from ghost calls (with some people/phones).

Cheers,
As for battery life I don't expect it will last as long as a 2D phone but IMHO the battery life is all down to correctly charging the phone (when I stick a phone on charge I never take it off charge until 100% even if I do take it off charge at say 75% I always let it run down then charge it overnight) and how much usage the phone gets eg, heavy use could be 6-12 hours very lite use 24-30 hours.
I should of been a little clearer on my question, my main question other then the one answered above is on general app performance, sound quality and usability how does this phone fair?

General app performance is pretty good. It plays most GPU intensive games well. The only games i've experienced lag for is GTA III and Dungeon Defenders. All converted 3D games lag.
Sound quality is excellent compared to other devices I've used.
However, you'll probably have to at least install a new launcher. The LG launcher is laggy, and pretty horrible. Most other LG apps perform poorly as well - the lockscreen takes around 1-2 seconds to start, the camera takes 3+ seconds.
Please do not get one, there are great when they work, sadly LG software support is awfull and with all the various different issues I genuinely couldnt recommend an LG phone to anyone.
I decided to take the plunge and changed from my HTC Mozart to the Optimus 3D (secondhand) and so far I am not disappointed,
Things I was expecting:
1, slightly lower battery duration (still in the process of priming my battery and so far I have got just under 23 hours medium usage)
2, it was already on GB 2.3.5 (V21A), kernal 2.6.35.7, build GRJ90 so was expecting some of the GB issues
3, half expect ghost calls but had zero ghost calls
Wasn't expecting,
1, odd battery stats (but after reading the threads on here looks like it is normal for GB on O3D)
2, better quality video recording (compared to me HTC Mozart which struggled on 720p recordings)
So now just waiting like other O3D users for a further update from LG but I am very happy so far with my choice. Come off it Samsung Galaxy 1 and 2 users suffered from various issues so no phone is perfect

I haven't had converted games lag but I use Juwes ram manager to set ram to hard gaming if I play a game and am low on ram at the time.
Lg launcher can as you say be replaced. I use nemus launcher but go launcher is also a good alternative.
LG should have put 1gb ram in at start rather than release an almost identical sequel phone with it later on but the phones good. I've considered flashing a new 3D rom but not dared to yet, but have read that using Thaiz rom is good.

Okay, I'm officially sick of battery drain. My first time with this issue was after flashing CM10, my GB build before that gave me the perfect amount of battery life. My phone would last throughout the day on GB. I got sick of the drain on CM10 after a week and flashed GB back to my device. My battery life has been normal the past few months on GB.
Since the official ICS builds were released I've been using ICS. I first flashed V28, battery drain was just like CM10. I flashed GB back and battery went back to normal. The next day official AT&T V30B was released, so I flashed it. Battery drain came back again.
Every single rom above GB has caused battery drain for my device. I've tried every suggested method I could find online. Flashing a different kernel, setting CPU Governor to hotplug, using nstools. I've done everything. I keep my phone in airplane mode, auto-sync is turned off, my brightness is at the lowest setting, gps and location settings are set to off, bluetooth is also off. I've tried charging the battery fully, pulling the battery out for a minute, charging fully again, pulling it again, charge some more, that didn't help at all.
My battery is dropping 10% in 15 minutes and all I have open is the web browser. This never happens on GB, no matter when I flash it. I don't understand what the issue is. I've also fully wiped my device internally and externally. I've spent a couple of hours trying to find an answer but nothing helps. If you can assist me, please take a minute and do so, this is frustrating. Thanks in advance.
Well generally yes. ICS+ drains a lot more battery than GB for a reason. Its running many more system apps and this can put a strain on battery life with the system working that hard "While Sleeping too". If you really cant take the drain.. Order and extended battery online. I suggest checking out the Accessory section. Good luck!

No. You are not. ICS consume much less battery due to the better RAM organization and memory killer. Just in many ROMs there is too much stupid programs and in many KERNELs are not optimized. Moreover people compare all data switched off of GB and the many process running by default in ICS that they can switch off.
The ROM/Kernel combination (by Acura) in my signature give me 48h battery life - the same like the GBs by Acura or Darkroom Team.
So... it is better not to compare STOCK GB with STOCK ICS - you never know the tweaks and running stuff by default. Better compare Developer GB with the SAME developer ICS ROM if you want to claim such a think.

nope. other way around. you never know what kind of sh*t is on is in STOCK, and you know that custom (developers) ROM are clean form most of them and tweaked for performance and battery. Stock mean ... "tweaked" and filled with bloatware by LG - nothing more.

True about the custom roms but you missed my point about the stock roms.
When someone claims for example that "the new xxx rom for my phone is worse/better than the old yyy rom", you have to ask "under what conditions". And in order to make a reasonable and reliable comparison, you need to compare the old and new stock roms and run the battery benchmarks only on those.
This is exactly what the biggest tech sites and magazines do when comparing the batteries. They run the tests on STOCK conditions/roms with as few apps as possible, apart of the stock apps.
Battery comparison is a delicate business. For example, even if you have the same two phones with the same stock roms, if the one phone receives a weaker 2G/3G or WiFi signal, its battery will finish much faster than the other one.
And if you start adding apps, changing to custom roms, kernels, radios and bootloaders then you have far too many factors in order to make a reliable comparison.
Okay, I tried geenify and bbs on a full charge and experienced no changes. My battery is dying quickly as we speak. My battery went from 81% to 34% in 5 1/2 hours in idle. I don't see how I'm having this issue and everyone else isn't.

"biggest tech sites and magazines" do PAID "comparisons" from A to Z. Do not trust any of them. Better compare best of X with best of Y. Or worse of X with the worse of Y. Like a scientist and like computer overclocker I know what means "Average" values.... there is no such a think. As i said - stock is just made by somebody... that is all... and here the developers are better. Moreover you do not know the current person how install the "Stock" Rom. If he did reset, if he still is on ext3 or on ext4. Does the person did a hard reset or not. Does still keep old baseband by installing the simple BIN or the BIN with baseband or the KDZ (bin+bb). different basebands different signal power etc etc etc... thats why i said BG of X with the ICS of X developer - they use nearly the same tweaks in all Roms with additions.
I had battery drain problem on all roms since GB untill v28b.
I lose about 1-2% during the night with wifi always on..I mean really always ON.[Thats 2% during 8h of sleep, on darkroom v2 i had 35% loss]
During the day my battery can last around 12h-15h..
My other,extended battery 3500mAh makes things a lot easier for gaming. I recharge them during the night and woooo..
V28b is the best rom and you should try flashing kdz with Mobile support tool like this:
http://p92x.acidhazardrom.com/guides/lg_flash_tool.html
There have been problems while flashing bin and fls but you never know, it's different for any user.
The second thing you should do is to erase or freeze any system app that you don't use.
For example I erased adrenalin6,gtalk,lg apps,........... and left only the apps that I really need.
I'm on stock v28b with the stock kernel and I have no problems.
And buy a new battery, maybe that's the problem..They are cheeeeep.
me to i have a very good lif batterie after flashe 28b i sharge it 100% wifi 3or 4 h day blut 1h day ande calls lyck always
for 1 day in GB v21e at 19:00 may batteri is in 20 or 15% CHARGE
in v28b for 1 day at 19:00 may batteri is in 55 or 50% CHARGE

That is too much loss IF what you say is correct that your phone is idle..
My O3D with wifi on and ICS during nighttime goes from 100% to 95% and btw my battery is the original that i bought with the phone back in the summer of 2011.
It doesnt run on stock ROM but it does run on stock kernel for now...
And btw guys forget about magazine tests and such BS because they are just promoters...
Never compare STOCK ROMS with CUSTOM ROMS because custom ROMS will always be better than STOCK, thats the way its meant to be.

I reverted back to GB, factory reset, now I'm flashing V30B one last time, I'll do a factory reset upon starting it up. Let's see if whatever has been broken the last 3 times gets fixed.
UPDATE: I think I got down to the issue. The phone isn't correctly reading the battery. I did a shut down and reboot and it went from 93% to 86% , I then plugged it in, shut it down and reboot again and it read 100%.
I'm done. I'll probably stick with GB til I get a new device.

You missed my point again.
Of course the good tweaked custom roms/kernels etc are far better than any stock roms, and not only in battery life, there's absolutely no question about that.
But when someone claims "the ICS rom has better/worse battery than the GB rom" it's much easier and more reliable to compare the ICS/GB stock roms than the custom roms, because of the much fewer degrees of freedom.
In a nutshell:
-Comparing, e.g., GB 21E stock rom with the ICS 28B stock rom: easy.
-Comparing, e.g., GB 21E custom rom which has different tweaks/kernels etc with an ICS custom rom which has again different tweaks/kernels etc: not so easy.
I'm having the same battery drain problem with mine too. Its driving me crazy to have to charge my phone 2-3 times a day

i got your point but....
lets hypothetically say:
1. Stock ROM GB give 75% of the max possible (best score of LG developers for 2 years developing from v. 10A to 21E). Stock ROM ICS 50% of the max possible (best score of LG developers for first leaked ROM)
2. Custom ROM GB - 99-99-99% of the max possible (best for developers A1, A2, A3). Custom ROM ICS 96-98-99% of the max possible (best for developers A1, A2, A3)
so...witch you think is better to compare - 50 with 75 from the max possible ("max possible" is the key phrase for speed, battery etc.) for LG
or comparing 98 with 99 for each GB or ICS custom... i would compare the last one. if 98 for GB is 16h and 99 for ICS is 14h ... then OK. GB is better. but not by original LG roms.
that is my point.
And another O3D tale...without happy end ;(
1.) Stock GB under heavy use (more then 3 hours of SMS, games & WiFi over the day) = A battery life of 13-19 hours
2.) Stock ICS v30a under minimal use (some SMS, little gaming and WiFi) = A battery life of approx. 10 hours
3.) Stock ICS v30a + ROOT, nearly no use at all over the day, no WiFi, (just 3 SMS) = A battery life of 7 hours.
After 2 hours in my jeans pocket = 68% of battery left
After 7 hours in ma jeans pocket = 8% of battery left (just 3 SMS written)
Then I read "Battery Re-Calibration" is of no use...and did not try it.
Then I read TaskKillers are nearly useless and un-installed "Advanced Task Killer"...didnt help. Re-Installing it didnt help either.
What is goin on here ?
May I suggest to check the CPU VRM (voltage regulator module) setting? I found out why, undervolting the CPU solved my problem. Voltage = ampere due to either linear and/or switchmode voltage regulator design.
EDIT: To clarify why voltage = ampere equations is true; ever wonder why PC motherboard gets away with shoving 100 Amps of power into the CPU without melting the 12V plug? In nutshell, battery trades amperage consumption for voltage shunted by inductor in switchmode VRM - in other word, battery have to work harder on higher CPU voltage settings but takes it easier at idle voltage.

I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.
Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.
