I really like specs of DHD it seems to be really great phone. Even if it lacks AMOLED display I still think that it would be phone arround. 4,3" display should be big enough to do light work on it which would include lots of browsing, emailing etc. I just wonder what do you expect from 1230 battery? I am still sticking to my very old but precious HTC Touch Diamond which is painfully slow and battery last only like 12 hours while I am using. So with all "improvments" (better cpu tech, older display and Android 2.2) battery life should be at least as good as EVO ? Thanks a lot for your opionions
PS I know that nobody will be sure until we get hands on DHD but at least we have something to chat about until we get final release date
The same DHD ROM on HD2 with base WM ROM optimizations gets me 1.5 day worth and its not running Android directly from the phone yet.
So I would guess it will be 1-2 days with medium-heavy use
x
Cool that would work for me Just wonder why EVO battery life is short? 4G drains more energy than 3G?
Not sure of 4G but rest is like this -
GSM : More Talk/Use time & Lower Standby Time
3G/HSDPA : Lesser Talk/Use time & Higher Standby Time
Hey guys, what do you think the battery life would be without 3g on? I dont have a data plan, and dont plan to get one (yet?), so i'll be using wifi for data. So with 3g off, and data roaming off, and even wifi off, what would u expect the battery life to be with moderate-heavy usage?

I think HTC lowering the size of the battery is a big indicator that the battery will definitely last you 1 day of heavy usage... I think if they was worried about the battery life they would have stayed with the 1400..

They are using unibody design for DHD that could be also reason since EVO has classic design with removable back than I would think that physically bigger battery fits to it.
Appart from SE X10 I have never seen a smartphone of DHD, SGS, Desire etc. caliber to last more than 2 days max. Even the SGS (wich has 1500mAh) doesn`t last more than 3 days (that was the max I could get from it) although the battery is not the one that GsmArena guys used for testing, does who know about the controvers around the SGS battery know what I`m talking about. So, I don`t think it will do better than 2 days (max).
I wish at least as a marketing tactic, they should keep same size battery (1400 mAh) as Desire. It's really annoying to know you actually downsize in terms of battery while you are making a device upgrade.

From my understanding the DHD consumes less than the Desire, so even a downgrade in battery total capacity does not mean you will have less autonomy.
I hope htc gets this right, i am really worried about battery life with heavy use.. It will be more power efficient compared to the evo 4g because the 4g uses a 65nm batt + likely the screen consumes more + the 4g is a battery eater.. but still i think the battery could have been a little bit bigger say 1320mah or even 1400mah, I hope mugen power or seidio come with a battery @ around 1600mah they can make that, the legend(Unibody) can have a 1800mah battery instead of the 1300mah that gives around 30 to 40% longer battery usage time in practice!
We don't know how efficient the new chip is yet. We will have to wait for reviews. But like all modern smartphones, expect it to charge it everyday. (if you are a heavy user)

Maybe HTC is right about less consuming maybe not, we will see but at least there are many people who directly look up the battery capacity and it a downsized capacity may them prejudge and not to decide buy. I know this is not such a big probability but If I were CEo of HTC, I would definetely go with same size battery with Desire but declaration with "less consuming" compared to Desire.

i think they were forced into using that size, otherwise they would have to make the DHD fatter to fit in a bigger battery.
dont think so,
Keep in mind that the DHD has a completely new processor in it with a new GPU aswell!
tests have shown that the DHD is 2x faster then a Nexus one with android 2.2! This new processor probably uses alot less power, and thus a smaller battery would be enough for atleast 1 day.
DHD sports a bigger screen than desire. when screen is on, I 'd bet DHD would drain more, whilst it could be less energy-consuming when screen is off.
To end this pointless thread in a whip:
1: 45nm VS 65nm - you can make the maths. This alone will yield a hefty decrease in power usage.
2 (a): the (only) potential power usage increase might come from the 4.3" screen, although that remains to be seen. WIFI/BT are standard.
2 (b): in order to decrease 2 (a), disable auto brightness and set a static, lower level.
3: Another contender for battery usage might be HTC's framework+apps+services. Once you get rid of the unnecessary, you'll save quite a bit of power. Once you get recovery and use an AOSP build (I HATE SenseUI), this will further decrease power usage.
4: In order to further tune the power scaling, use an UV/OC kernel + proper scheduler ammendments (once HTC posts the source on the dev site). You can tweak the latter with in the meantime with temp. root and a user script targetting /sys values.
I guess that should cover the basics.

hey man..there are rumors spred about new chips on board from sandisk with lock on nand. there's a chance that hd2 will be as u unbox, for a long time. just hope it could be possible to undervolt the same kernel provided from htc.
Or maybe not, everything has a weakness, even the lock on nand we will just have to wait...
This is not another thread about battery life obsession. It's more about a curiosity.
I have my Evo tuned so that it has great battery life on standby. When I use it for anything--SMS, data, local apps--the battery drains very fast.
I know that data, CPU, and display are the major consumers, but...
I have a Nexus One, with also a 1Ghz Snapdragon, and almost exactly the same loaded apps. Same screen resolution, both on 2.2. Both have 1500mAh battery. The only difference is the display technology and radio (GSM/EDGE/HSPA vs. CDMA/1xRTT/EVDO).
When used equally, the N1's battery does not drain nearly as fast as the Evo. How come? I know AMOLED is supposed be more power efficient, but by that much? I know CDMA can be less efficient, but again, by that much?
- - -
Duh! Edited from Hummingbird to Snapdragon (got confused-I just picked up an Epic which has Hummingbird). Thanks for correcting.
They both use Snapdragon, Hummingbird is Samsungs CPU codename, it's based on the same architecture but uses a smaller process.

Is it something new, or has this always been happening?
Was it after the new update or kernel WHATEVER, that you flashed?
If you’re running the stock kernel, do you think the fact that the screen is physically bigger may have something to do with the difference? I’ve always accounted the difference in the battery drain speed (between screen on and screen off) to the fact that most of us are running tweaked kernels that are overclocked when the screen on (with 5 point multi-touch, etc), and underclocked with the screen off.
The problem with battery life issues is that most of the time it can be just a perception and not scientific evidence at all.
Personally, I had an iPhone 3GS prior to getting an EVO and I would say the same exact thing happened with my iPhone. Especially when I was playing games. It doesn't seem to happen with my EVO.
Even seemingly silly things like the Battery Icon can help with the perception that battery life on the phone is bad. Since it only has 4 levels, it kind of tricks your mind into thinking your battery is draining really fast. Try flashing this.
Scientifically, The difference in battery life running the same exact apps under the same exact conditions would be almost negligible between an Evo and a Nexus one. You could even test them side by side and see for yourself.
Also, some facts:
- CDMA 3G is LESS power hungry than HSDPA when actually using it. Heck, EV-DO even uses less power than CDMA 2G(1xRTT)! Wi-Fi uses even less, so use it whenever you can.
- There's a huge misconception that AMOLED Screens use a lot less battery than regular LCDs, but in fact, that's only when the screen is showing LOTS of black color. During a web browser session with lots of white webpage viewing, AMOLED has no Power consumption advantage over LCD.
Signal is a HUGE contributor. I get about 12 hours out of my battery 3-4 out of 5 bars. I went to the sand dunes and had 5 bars and my phone lasted 28 hours.

there are some variables here - my router at home sucks, so I actually get better signal (and battery) with 3g and not wifi unless I'm in the same room as the router. Like the guy above me said, signal plays a huge part in it.

When I run Handcent, N1 uses about 20% less battery over ~400 messages. Browsing sees similar results. No exotic apps and I keep close eye of what is running/syncing in the background.

On both phones, I have a % battery gauge. I use both phones in good coverage area and have observed them over weeks of use. I would use one phone for the day, do the exact same thing, use the other phone the next, and consistently see the N1 having 20-30% more battery at the end of the day. I'm thinking of loading "current widget" to see the drain rate between the two phones.
On the subject of radios: I have seen manufatures list longer battery life for EDGE vs. HSPA and the same for 1x over EVDO. Also I [think] usually see longer standby times for a comparable GSM/UTMS phone over CDMA (e.g., Touch Pro2 on GSM/UMTS vs. Touch Pro2 on CDMA).
When one says that EV is less power hungry than 1x, are we talking about a time-use comparison or efficiency? Example: 1Mb download, 1x takes, say, 1 minute, while EV takes 10 seconds. Yes, for that download, EV took less power. But if one were to have 1x & EV both running for one minute, which takes more power? I ask because I remember seeing EV transmitting at higher power than 1x.
I've been seeing a LOT of posts to the effect of "all Vibrants vary", etc... I'm not talking about Vibrant 3G vs 4G or Bell Vibrant, we all know those differences.
What I'm referring to is how phones that are supposed to be identical act and perform vastly different. This leads frequently to claims of "LIAR" and flames, etc. I for one admit I find myself unable to believe for a second anyone that claims to get more than 10 hours of battery life on a GOOD day with a Gingerbread ROM, but people have posted screenshots of 16-25 hours with supposedly stock batteries.
The things I've noticed that are "different" about everyone's phones:
1) Some wipe the SD Card frequently on updating. Others never do.
2) Some came with no hardware access to download mode, some had it.
3) Some have awesome GPS, others have terrible GPS, which leads to #4
4) GPS fixes that improve one phone actually make the next phone WORSE. This is illogical unless there are actual differences in the GPS Radio...
5) Some get decent battery life on Gingerbread, while others are completely unusable, starting to visibly drain the moment you pull them off the charger. And this has no relation to battery life on Froyo, eliminating possible actual battery or user differences.
I did not include overclocking ability, because that's normal with the tight tolerances on CPU production runs. This other stuff, it's just not normal if everything internally is the same.
It just seems too much to be quality tolerances. As I said, people are coming to blows over some of this stuff. When I see someone claim they get good battery life on Gingerbread, and that all it takes is calibrating your battery, I want to bludgeon them over the head with my phone that drains 65% of its battery just sitting there idle for 8 hours, or 40% drain if I'm using my extended battery... when with Froyo, I get 1 or 2% drain in the same time period. But certainly people are getting "decent" battery life.
Even more strangely, it seems like when the phone was manufactured doesn't seem to matter. But the differences, especially in claimed battery life on Gingerbread, and the tendency to have GPS fixes work on one phone and actually 100% fail on the next, makes me wonder if there isn't some issue that hasn't been identified. Are there perhaps 2 different parts suppliers for some component in the phone, that perhaps Samsung is aware of and has written around, or compromised to, which would explain mediocre stock GPS performance, or what is going on?
Are there other differences people have noticed? I'm wondering that if maybe we can somehow identify the actual differences or some pattern, maybe it will clue in the more experienced developers as to what it will take to fix these issues. Currently though, as each developer typically only has 1 or 2 phones, their own, to test on, they can't easily test on both the "good" and the "bad" vibrants.
For example, if you've swapped a Vibrant on warranty, have you gotten one back before that had markedly different characteristics? Notably faster or more laggy than before, drastically different battery life, etc?
What do y'all think?
I have switched out 3 vibrants and this last one is a bit faster but the gps seams more lagging than my last one also I have noticed screen color and brightness differences as well which in part could be responciple for the battery drain. You would think a company such as samsung would have there stuff together.

Well mine is odd i can say that. My stock gps never worked. Once i rooted and started using sgps fix i had no issues. I get great battery life on gingerbread (24hours plus on moderate use) but cannot get a gps lock no matter the fix. I cannot run cm7 either it will drain an entire battery in 3 hours if i do. I can run a stable overclock on gb or froyo at 1.6+all day long with no issues.
My wifes vibrant is about the exact opposite of mine i can run the same roms and kernels but hers will not handle overclock or compare similar in quadrant or running 3d games. So yeah its not just you there is something oddly different in these so called same devices.

I get 22+ hours on every rom I have ever tried and I have tried almost all of them. My gps has also worked well on every rom including gingerbread. I'm using trigger right now and it easily gives me 20 plus hours with screen on over 4 hours...not that battery matters much. Every one should have an extra battery even if it's a cheapy one and there arter ton of those around.

You also have to take into account that the parts of the phone can be slightly or vastly different.
Just from a manufacturing stand point in general I can say with utmost certainty that no matter what steps are taken to ensure identical parts across a line of anything there will always be differences. The time my circuit board went through quality control may have been the end of a shift and the person may have cared about their job a lot. The line stops next shift comes on and a slacker who just got dumped by his girl checks the very next board that may not quite meet spec. This is just one example.
My other example is that of processor chips. As far as computers go, and I'm sure its the same here, the chips are made from a large wafer. Toward the center is higher quality and the edges are lower quality. All these chips meet the minimum requirements but the ones from the center could probably be meet the minimum requirements of the next level chips.
This doesn't even take into account all the outside factors after manufacturing. Yours goes to Tulsa with Mr. UPS and mine comes to Florida with some temp Meth head that managed to fake his way into a job and decides that since its the basketball playoffs he wants to be Lebron with my package.
I hope some of that makes sense. You and I can take the exact same steps to wipe and flash but because of the far too many factors that can make our phones different we may or may not get the same results. All we can do is try to get everything to an optimal place that it works across the majority of phones.

i think it also depends on when and where u bought your phone from can effect your device, for example on froyo i had good battery life 15 hours with moderate use and great gps, but with gingerbread i get about 18-19 hours on moderate with cm7, my gps barley works and any gps fix has no effect on it, my phone can handle slight UV but anything under -100 it gets unstable but i can clock up to 1.7ghz stable i tried 1.8 but that made it crash, so i guess its also based on luck
I had great results with the s.gps.2.zip file flashed on top of Bionix 1.3.1 on BOTH of my Vibrants (mfg. on 10/10 and 1/11). I've been lucky that they both mirror each other in anything I do to them.
Now you gotta take in consideration that you can't go by what everyone claims here regarding their battery life. I'm not calling everyone liars but there are some that you just gotta throw the bull**** flag on them. I seen post claiming that they got 50 hours of battery life (maybe on standby) but I don't see that happening with "regular" use.
Now wtf would you consider "regular" or "moderate" use? Nobody knows cuz every one's use would be different.That's why I feel you can't go by that claim. I can't tell you how many hours I get on a full charge because I can't clone what I do with my phone everyday to give you a number. There are weekdays I have 70% from 5am-4pm and others I'm changing my battery at 4pm cuz I'm on red. I know for sure though that its a hell lot better that when I was on stock.

If I was able to get 22+ hours on JVP/Q/R GB *or* CM7 I'd be there in a heartbeat. Unfortunately although I can easily get 30 hours on Froyo with my light usage and the STOCK battery (we won't even talk about my Momax), I am lucky to get 10 hours on any GB...
The thing is, these differences are not "minor", they're HUGE differences that people are experiencing. When I say I'm lucky to get 10 hours on GB, I'm saying I can put my phone onto 2G mode only, lay it on the nightstand, and wake up 8 hours later to find 50% of the battery drained - without having done ANYTHING. And then do the same with Froyo and only drain a couple of % - with the same installed apps.
On the CM7 threads and the JVP/Q/R threads it's typically "Well you won't get as good as FROYO but it's acceptable", and that's just not the case with a good portion of users.
I don't blame the developers, of course... what I'm saying is there's SOMETHING, given all these differences, not just battery drain, that is different about these phones that hasn't been discovered. It's enough to make me want to exchange my phone before the warranty is up in September "just to see" if a different phone would be better.
I think mine is the most "common variation" of the Vibrant
- Received the contract through an authorized reseller first week of October
- Not hardware locked
- Never had mysterious sd wipe issues
- GPS worked (locked anywhere from 2 minutes to 5 seconds depending on settings) but will suffer occasionally from horrible, horrible drifting issues (too afraid to perform hardware fix). Interesting to note, s.gps.zip worked wonders but s.gps.2.zip (or whatever it was called) completely broke my gps.
- Never bothered to test if I could overclock or not, but my phone has had the freeze of death when underclocking to 100 or 200 mhz.
- Everything else worked as it should: odin (never had a failed flash), voodoo (never had the not enough space error), etc. etc..
regarding battery life
- pretty standard, custom rom or not, I was able to go through the day with 1 charge (eclair and froyo). Best was Axura 2.x with JK2 modem (around 26 hours I believe).
- GB. It hasnt been as nice as froyo but I believe the devs have done their best without a Vibrant-specific leak. It could last a day, but thats being very generous with screen on time and usage. I believe the GB roms will be on par with froyo if we recieved a leak of our own..

Dear People,
I am posting this out of big ENVY from my friend's story of his iPh*** 4 battery life with 40hrs ++ of usage (social network on, moderate usage, data always on, bla bla bla) and he still got 20% left of his battery!!!
I was just wondering did anyone managed to experience 40hrs ++ of battery lifetime? My best achievement with my nexus s battery life is
1 day 3 hrs with
MIUI Rom JB 2.8.17
Marmite Kernel 4.3
SmartassV2/deadline
100/1000
Automatic brightness on
Could we EVER achieved 40hrs ++ battery lifetime??? Since Iph*** 4 has practically same specs with Nexus S
It has 1Ghz procs, 512mb ram, 1500mah battery, bla bla bla
Any comments?
A very big advantage of the iphone is the very dim (to my opinion) screen backlight. If you change that to default 1 min instead of 20 on a custom rom, and then change your auto brightness values as well to lower ones your lifetime should increase alot. At least mine does. Also I use Llama to close mobile data after 5 minutes of sleep and then instantly turn it on on unlock. Anyway..we will never be able to win versus apple at some things. They have one operating system made for one device. We got one operating system for like..1 milion devices? That's the same story of console vs pc games.

I've been getting pretty excellent battery life lately, will put up a screen shot but got almost 52hrs battery life with wifi and 3g on until it got to about 15% with about 2h 24m screen on time, although this was pretty light usage to be fair.
Using codename 3.3.2 with standard kernal, I turned NFC off and this seemed to help massively although I've also heard the new Maps app has solved some battery drain so not sure which has contributed the most.

52hrs?????? Cant wait for your screenshots man!
You may think the specs are the same, but the hw in the iPhone and power management is still superior. They get a push notification, even while the 3g radio is in idle and almost off (in which it saves more power). It's hard for Android to optimize the power management specially because of that many hardware variations, it's not only the CPU that counts.

Well, thats good to know, but since its the software differences (meaning coding and stuff), surely (i assume and hope) that we could also applied it (somehow) in our devices through tweaks, can we?
IMHO not much is possible since this is older hardware already and a question for how long will Google bother with it. It might be alot of work needed and you gain some insignificant amount of savings.
Would be nice to see some kind of power management tweaks in coming version of Android though.
well its halfly because android works differently and half way because of the hardware.
yes, the hardware is similar, but the nexus screen takes up more power, the processor is not very efficient, and nfc takes up power... also, the 3g radios are honestly HORRIBLE on the nexus s and that might have something to do with it.
but, the software side does make a major impact. iPhones do not multitask like android, which saves power on slower devices like the iphone 4. thats only half of it though, for instance, the iphone 4S has much worse battery life than the nexus s (by far). ROMs make a big difference also, I am very picky when choosing a ROM- if it doesnt have great battery life then I immediately replace it by another ROM that does.
I get on average about 16-20hours pretty consistantly if you are wondering, and I am OK with that as long as it makes it to the end of the day... I wake at 3:30 and normally it does. My advice is to experiment with different ROMs, I would suggest some, but I use an S 4G...
I don't really believe it. My friend has an iPhone and he uses it quit a bit and seems to have to keep it plugged in as much as I keep my phone. I think he said he usually gets about 8 hrs out of it. And the screen is pretty dull compared to mine so that might make a difference to

The iPhone screen is a lot smaller too and that's a big tradeoff.
I always get a chuckle at the iHerd people I see on the bus holding their tiny screen 6 inches in front of their face so they can read it.
If battery life is really a concern get a couple of spare batteries and a charger.

Lasting 40+ hours is easy if you don't use the phone much...
The screenshot was taken on a long weekend a while ago. I was busy during the weekend and didn't use my phone much apart from listening to music for no more than 2 hours.

Thats true, but from the iphone their data was on all the time, mid moderate usage.
But, just like some people said, power managwment chip, the os, makes big differences

Are there any comparisons of the two cpus available on the s4 when it comes to battery life? Thats the only reason for me to try to get an exynos version if its shows to be better in that respect.
Yeah, that's a good question I want to know the answer too, there are many people having testing devices but they are too hungry about testing the damn processor and gpu instead testing properly the battery life. -_-

Lord knows battery Life is very important to me.
the guy that's testing whatever people tell him to test said that when his battery got down to 30% it lasted like 3 hours with max brightness and benchmarks running

With wich cpu? Also no comparison to the other version mentioned here.
I'm not convinced, even with S3 you can spend all the battery juice in 3 hours if you want. To do a proper test you need to leave the device doing the same job like an Snapdragon S4 during the same time.

Octa has a longer battery life than SD600.
That's why samsung used 8 cores technology.
And by the way the 5inch HD screen saves power too for both version

Thaty what one hears, yes.
However I would like some actual test reports - for instance how long does the phone last for web browsing, for video playback and on standby?
I would like to see actual numbers.
As for the screen:
It is said to use 25% less power compared to previous amoled display generations. However that 25% value is something we have to trust samsung on I think, at least I have not seen any actual tests on power consuption of the display alone and it's probably not easy to test.
The way they have managed the display to consume less power is to use use phosphorescent instead of fluorescent green diodes, which use way less power. Until now they could not produce the green ones with an acceptable lifetime. The red ones have already been phosphorescent, and the blue one are still fluorescent since they are hardest to produce.

This. This so many times over.
So many people are parroting the "Exynos will have better battery life" thing but this really remains to be seen.
If the better battery life is in exchange for crippled A7 performance at inconvenient moments then it's useless. If better battery life isn't available for when you're using intensive apps then it's also useless.
