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.
Okay, needless to say, operating systems like iOS and Android are improving plus the new processors heading to dual core. However, battery technology is way behind I think. What improvements are needed in this field to get a smartphone working for a week on one charge (not realistic but ideal)?
Fuel cells?
New alloys?
What would work to help our battery technology which is falling behind?
Battery technology is far behind but it has been for over 100 years. For electric cars Toyota claims to have a new battery with 2-3x the power density of current batteries. Although for general purpose I believe Lithium Phosphate is still the current state of the art technology.
Fuel Cells are neat technology but not yet that practical just like 10year miniature nuclear cells.
The biggest problems in my opinion are
1. phone size (everything is getting so thin or small in general) leaving less room for a battery
2. screen size (huge touchscreen = big power draw), and other things too that impact battery life.
3. things that run in the background keeping the phone cpu in something other than its lowest power state
4. screen brightness. Seems trivial but can make a big difference and I think all phones should have ambient light sensors are change automatically.
5. internet connectivity. It goes along with #3 in that it wakes the cpu, but also the current wireless chipsets don't seem all that energy efficient. Using any connectivity cellular, wifi, or bluetooth really eats the battery. Many report turning off wifi, bluetooth, and using 2g when possible significantly improve battery life.
Personally I have the biggest battery I could get for my phone and my laptop too. My 17" laptop runs 4.5 hrs at lowest brightness and 3 hrs at the brightest setting. Most phones aren't much different.
Sorry long rant...... does that break down your question correctly?

It sure does for me thanks
nova display and amoled plus is good for battery
li-po is more efficient than li-ion
dual core is more efficient about 40% than single core (in ginger bread)
Have upgraded my 9023 to 4.0.4 after rooting. The UI and animation are visibly faster but the battery life seems to be the same. I read some people say the battery life is better... Is there an optimized settling for the same? Also what is a better setting for the brightness? Minimum or Auto?
Thanks
Doubt the battery life is going to be noticeably better or worse. The main change regarding the battery is that they fixed the battery stats, it calculated the AndroidOS usage wrong which skewed all of the results. This has no effect on battery life.
Thank You. Could you also suggest what is the optimal brightness setting to save battery? Minimum or auto? Common sense would suggest minimum but I have seen a lot of people say auto brightness works best?
Minimum saves the most battery. Auto uses a tiny (negligible amount) bit more as it powers the photodetector (light sensor) while the screen is on, however it will scale up the brightness when there is excessive light in the room, and lower it eventually when it's dark (this takes longer than i'd like, some ROMs allow adjustments). Generally, it's best to keep it on auto unless you know the conditions you will be in for most of the day.

Thanks Harbb for your contribution ...
Honestly 4.0.3 was fast for me (and faster by the way from GB)...I never noticed 4.0.4 is faster than 4.0.3 in anything but maybe a bit in browser ...
Thanks Harbb. Will try on auto.
I am currently on stock Android 12. I flashed the unlocked stock image (non-verizon) a few weeks back. With Android 11, Android 12, LineageOS, etc. every browser I have tried including Chrome, Brave, Via, etc. all drain the battery way faster than browsers did on my previous Moto G5 plus. i would say when I am surfing the net on my browser (usually just reading forums, no video), the battery drains about 1% every 5 minutes or less. I have tried 2.4Ghz wifi, LTE, etc. and data connection type doesn't seem to impact anything.
Is this normal for this phone? anything to do to reduce browser battery drain?
If you go into battery usage graph, is the browser the only app listed as using up the battery (and not the screen brightness, or another app that may be contributing to the heavy usage)

correct. if I am using other apps the battery drain isn't near as severe. I keep the display setting "extra dim" enabled all the time and I keep it down as low as I can tolerate. I use a pitch black wallpaper use dark mode in browsers so they have mostly black background with white text.
Phone idle is the only other thing that seems to use a sizeable amount of battery according to the battery usage data in settings.
Sounds about right. Came from a Moto G7 Play (15 months back) and saw similar drain rates. All three devices have similar battery specs which plays into the units being used to assess drain. Is what it is.
FWIW - Opera

Not gonna lie, it makes me want to go back to Motorola when this Pixel bites the dust.

Many Moto's bring a nice package with unique tricks. Gotta do your homework on what features are most important when the time comes.

I definitely did that. I only got the 4a because it was the perfect size and had a headphone jack. I assumed with a newer hardware set and similar sized battery compared to my old phone batter life "should" be better. Nope.
Na, it's more complicated. 4a sports more sensors, brighter/denser display, faster processors, etc. System and personal apps clearly play a role in longevity (behind screen brightness); you'd need to do a detail study to understand what's drawing when and why.
I use to fuss over such matters but find the device lasts a full day for my use case which is all that really matters. Charges up quick from a modest size battery pack when camping/traveling. Just like past Motos.
Not sure who I'll partner with in the next dance. Love Pixel cameras (especially in challenging conditions) and routine updates. Miss some of Moto's innovations, like active display and actions. Needs to be close to AOSP; no Samsung UX butchery. In the end form factor will likely be the deciding factor once non-contenders are ruled out.

I don't know what CPU you came from, but if the Moto only had "small" cores then of course it used less battery. "Big" cores use more power. They go faster too, but if you have a constant load, then they'll eat battery faster.
I don't know if there's a non-root way to disable the big cores, but I suspect you can do it with root (but don't know for sure).
Otherwise, you gotta get your browser to stop running JavaScript. If you're watching video you need to make sure the browser is offloading all the decoding to the hardware codecs rather than doing it on the CPU.
And if the screen is on, it might help to try and get it "more black" (eg. Use night mode) or turn down the brightness. The screen is often the primary user of power when a device is being used.

Thanks for the suggestions. My power complaints are just limited to the browser so I dont think it is just the larger CPUs. I think my standby consumption issues are related to Stock Android as I am now running GrapheneOS and my standby power consumption now matches my old Moto G5 Plus.
As for browser usage consumption, I have tried everything but disabling Javascript. I will try that and see if it breaks anything I use regularly. Thanks for the idea.
tangent back to general power consumption, I typically disable just about everything behind the scenes as I can. I keep the theme on pitch black. I use the extra dim setting to keep screen brightness as low as I can tolerate. I use night mode in browser to keep as much black background as possible. I disable all tap-to-wake or sensor based features. When I was trying to run Android 12, I disabled all the smart services and removed all the google apps I could. I removed all permissions I could. I restricted all apps I could. I disabled adaptive settings, etc. There is a bunch of stuff running in the background on Android 12 and I just could not

I dont think it is all the phone. GrapheneOS has 40% better standby battery usage than stock android 12. On graphene, it matches my old Moto G5 Plus. It is either lazy programmers with inefficient coding these days or it is google having the stock OS do waaaay too much by default with no way to disable it.
I'm trying to figure that out now.

I totally agree on the lazy thing. So many devs now days are so lazy. I develope QuickBase databases and constantly run into extremely poorly setup realms/apps. Just basic stuff. Lol
hey guys !
iv got real issue with the flip 4 , i like the brightness to be full and also the extra brightness
but every min that i just do simple stuff like open face book or just playing few sec with the phone my phone begin to warm in the upper side
and the screen dim much , but i only do stuff like few second so whats the point of the brightness
im at home and its not hot in my room.
maybe its defect of the screen or its like that ? cause when i hade s 22 ultra it also dim screen when get warm and the iphone also dim the screen when become hot but in the flip 4 i just do simple stuff and the screen dim then even the brigthness slider when i play with it is not function wtf? can you help me thx
Why are you burning up your retinas? Dim light isn't harmful to your eyes but bright light can be.
There absolutely no reason to use full brightness indoors all the time.
Moreover full brightness greatly reduces battery run time, lifespan as well as display lifespan.
It's best practice to not use these devices in direct sunlight... it will rag them out.
If you're hitting the thermal limits of the device and its battery or cpu core temps are too high ie the device is operating within normal parameters as opposed to a defective thermal sensor all you can do is reduce the load.
By turning down display brightness, reducing bandwidth usage and better optimizing the device to reduce power consumption. What's it's average mAh usage? SOT?
Heat is the inevitable byproduct of power consumption; reduce power consumption to reduce the heat.

Is it just those 2 social media apps doing this?
I don't allow any social media or shopping apps on my phones. Trashware at best, spyware and/or malware at worst.
Just general use outside/car mine gets pretty warm and screen dims. Compared to my S22 Ultra it rarely dimmed but also a bigger phone
You likely know this but it bears repeating:
The processor and other circuits are mostly on the upper-half of the phone, near the camera. These chips do get warm, even hot, when applications are in use.
A lithium ion batter, when being charged or discharged, gets warm, even hot, depending the current flow needed to operate the applications, chips, and screen.
An OLED display can get warm, even hot, when lit brightly.
An OLED screen in sunlight will get warm, even hot, even if powered off, because it appears black.
Outside, if the OLED is bright white, it still gets hot because turning on all the pixels takes power, which is expressed as photos (light) and heat.
A very compact phone, like the Flip, has little surface area to expel heat. It doesn't have a fan, so the only way the phone cools is by convection (passing heat to the surrounding air) or transferring heat to your hand or (don't try this) water.
A folded Flip has about one-half the area to dispel heat because the screen cannot effectively radiate heat to the air or your hand.
Some applications use a lot of processing power even if you think you're using them. This is why so many people on this site discuss removing and/or disabling applications.
You can check in Settings --> Battery and Device Care --> tap on Battery --> tap on the graph, and the phone will display which applications are using the batter.
It's my understanding that the processor, battery and screen all have "checks" to ensure they don't get too hot, and Android can throttle these components to prevent wearing them out, burning them out, or causing a fire.
Hopefully others will better understand some of the challenges Samsung has in creating such a unique phone.

My flip4 is up and running and no negatives so far. Just slightly warm while I was downloading over wi-fi some 15GB of my music. The overall quality of this phone is pretty good, just like my S22, but it folds to 1/2 of S22 in size. Spent several hrs setting it up and debloating, I always do these things manually. This phone is very responsive and operates smoothly.
On the side note: picking up the delivery from Bestbuy, rather than getting it to my door by Fedex, wasn't a good idea - now I have to look somewhere for an mt box for packing up and shipping my trade-in, Bestbuy just handed to me two small retail packages w/ the phone and silicone cover. They don't handle trade ins.
