Expected battery life of DHD ?

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...

Samsung Galaxy S II drains battery too

Hi
If you look at this youtube video it looks like Samsung Galaxy S II also drains batter fast.
Or simply look at this picture and compare battery and time!
I guess they did not think about that when they made the video

This is Stupid. ... How can you conclude it like this. .. !!! Come on man ... Find something proper to post....

Actually looking at the video it seems that the SGS2 charges its own batteries!1
First the battery is at the red level and after that it is back to green level!

dude, it's a prototype, samsung will fix all the bugs before it gets out.

they could use more than one GSII....

What do you guys expect? Battery to last a full week? They made the battery 1650 mAh now.. Screen is bigger, other fancy things.. It's normal that a phone like this will eat battery. It's a half computer!

have you ever been to an expo like MWC?
devices change hands all the time and get max 30mins of charging before they are given to the next journalist...

I agree, just like they fixed the gps bugs on the galaxy s before release.

The bugs are software related, not hardware - so that gives room for xda developers to start twinkering and improving

You can't make good conclusion on just that.
But...

Has anyone actually seen the back-cover off displaying a 1650mAh Battery.
I'm not saying the SGS2 won't have one but until I see visual proof I'm running with it being a 1500mAh, regardless to what the written spec states.

Batt consumption can´t be worse than on my HD 2. SGS2 has AMOLED screen which consumes less batt power by 25 %.
But since this is really an "ALMIGHTY" phone one will use it for everything during the day, so will batt-drain SUBJECTIVELY be big...........

What a waste of forum space......a device that is just hitting the market, you didnt even try it yourself, and already speculating about battery performance!!
BTW, which high-end Android phone which such processors, dont drain the battery ??

I am talking about 1000 MHz processors and up.
Do you really thing that a dual-core 1000MHz + processor are going to consume less battery juice than a 480Mhz processor used in some symbian devices?
Can you point out a Android device that is not "draining" the battery?
Which part of "wasting forum space " you didnt understand?

Well you are comparing 2 different things. Android allows you to run apps in the background which uses battery, it has a touchscreen (most symbian phones don't have that) which is a huge drain.

It isn't even out yet.

[Q] upgrading from nexus s to nexus 4

at the moment i've got a nexus s and am seriously considering moving on to a nexus 4, i was wondering if anybody else has made the same move as i would like to know how is the battery life on the n4 compared to the ns. i assume it will be worse but i'm hoping it isn't that much of a difference. thanks

made the switch about a week ago. for me the battery life is definitely better. take note that the nexus s only had a 1500mah battery. the phone is a bit big but im quickly getting used to the size. this phone is also lag free.
thing that bothers me is that the phone gets really hot. mine hits 43 degrees celcius when playing games. im thinking of rooting to undervolt it.

The N4 is slightly more power hungry i would say but it is nothing a custom rom cant fix.

my previous device was a Nexus S. I made the switch when the S started to lag/freeze real bad and the battery started draining rapidly. I'm not one to switch devices every year but I'm glad I waited for the N4. Performance is buttery smooth, screen size is awesome, and battery life is excellent. Only minor gripe is that after rooting, it seems my phone sucks up more juice..but could be an isolated incident.

43 degrees is not hot... I'm not sure if you're talking case temp or die temp but put it in perspective - the SandyBridge quad core in my desktop PC doesn't throttle 'till 97 degrees C and the ATI GPU in the same system is similar (not that I'd let them get that hot, but Intel and ATI call it 'safe') Obviously this varies from chip to chip, and a CPU running at 80 degrees C is going to make a tablet or phone pretty difficult to hold on to but I'd imagine the limits they've defined are more about protecting the user and the battery (Li-Ion batteries don't like getting hot...) than the SoC itself. Also, the power consumption of a silicon transistor is directly proportional to its temperature, voltage and switching speed. If you let the device get too hot, battery life would go south quite rapidly.
Without undervolting, the Tegra 3 in my Nexus 7 will hit 70+ under simultaneous GPU/CPU load and this is how Google/Asus/NVidia shipped it, so seriously... Don't worry. I don't have an app that can monitor temps on the N4 and neither do I want to know so I'm not about to start fishing about for thermals in sysfs, although I'm sure it's cooler with a 200mV CPU undervolt than stock
I once peered into a rack owned by a client of mine to see one of the servers with a bright red flashing light on it... I asked the guys "how long has this been happening?!" - 4 years of running under high CPU loads at 90 degrees with a ceased fan wasn't enough to kill it, I doubt much will.

ok thanks for the replies was a bit worried that the battery life would be considerable worse but you've set my mind at ease, nexus 4 here i come :good:

With the right ROM and kernel, the Nexus 4 is giving me the best battery life of any Android phone I've yet owned. Admittedly, it was just light browsing and youtube-watching, but I got 7 hours screen-on through my last charge cycle... Which is double what I got out of my One X with the same kind of usage!
You won't regret it Just don't put it down on even slightly slanted glossy surfaces with no case covering it... LG appear to have invented the perpetual motion phone!

Wow, still can't quite reach seven hours. Most I've had is about six and a half.

Made the jump myself about a week ago, my Nexus S was starting to lag quite badly and reboot itself a lot. Nexus 4 is leaps and bounds better, no lag, love the screen and battery life seems a little better but not much to be honest, might try rooting and see if it makes a difference with a custom kernal. Very pleased with it overall. Only thing I dislike is the lack of a removable battery and lack of sd card slot but will have to live with it.

[Q] battery life comparison exynos vs snapdragon?

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.

will overclock harm my device？

I am using a custom ROM (CM 10.2) instead of stock ROM.
I found it has more specific functions , it is awesome .
However, I noticed that the CPU and GPU frequency were set higher ,especially the GPU , was 20% higher than default.
will it harm the hardware？
I AM WORRIED ！

Well, it wont harm your device. But your battery life will be a bit shorter and the device will be warmer, especially when you play on it....

That depends on many factors. Likely in short term no, long term it lowers the MTBF. The truth knows only the SoC manufacturer Qualcomm.

And get annoyed by random app crashes

I can tell you this, every single device I have ever owned with the exception of my current lg phone got an overclock at some point and kept it. Every device I've owned save a few I sold or got stolen and don't know about still run today. Damage and overclocks have a lot to do with if you exceed heat ratios of the parts. A factor in longevity concerns is also just how long you plan to keep a device as well, most don't exceed 2 years.
Another would be the longevity speculations of the hardware, for instance, your battery will almost invariably lose it's functional life within 2 years under moderate to heavy use. The capacitive screen on average may receive 225 million clicks before borking. Since all of this technology is relatively new time frames can get sticky but I would think it safe to expect 1 year from a heavily used tablet And hope for 3-4 years with a battery replacement.
Therefore when calculating being on the high end of the heat ratio for a SOC with a longevity expectation of 9 years at moderate heat thereby possibly reducing life by a few months would not play highly into my calculated risks. However you must make sure to stay at reasonable temps for your SOC.
