[Q] Battery life

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.

Stock Battery has issues!! [READ]

Ok, so i did a lot of research on HTC Sensation battery, and turns out its not an environment friendly battery. Infact if you've noticed, our phones heat up a lot and SUCK the hell outta the battery. HTC has to do something about Sense taking up so much RAM and memory.
Thanks

I agree 100%. Replacement of a diff one would be nice.

RAM and memory are the same in the context you used. And what does RAM usage have to do with the performance of the stock battery? NOTHING. RAM being used does not drain the battery faster. In fact, I want my RAM to be used, not just sitting there doing nothing. As long as whatever is using the RAM releases it when I need it for something else (sense does) I'm happy.

Ya, I'm not too sure what the extensive research has revealed...the OP doesn't substantiate why stock battery has issues. Or what it has to do with RAM usage. Sure the battery has small mAh...but it doesn't require a lot of research to see that (as it is written on the battery).

I've made this statement before but then about head
Take your laptop off the charger and just leave it there most normal battery's of a laptop shouldn't last longer then 3-4h
The hardware of this phone is similar to a old Packard bell dot-s (the 2007 model)
1.5 ghz dual core with a 4.2 inch qhd screen is consuming a lot of battery usage. Nothing wrong with sense. Its allready build for the best performance and battery usage
If you want better battery life buy an anker 1900 or the 3800 something battery

Its not only the Sensation that has this 'issue'.
Its common knowledge that any smartphone has poor battery life.
Not really gonna last much longer than a day.
At the end of the day, we are probably near the top limit of what Li-Ion batteries can do; Need a new type of technology to supersede it.
(PS, the most I got out of one charge cycle on my Sensation was 1 day, 11 hours and a few minutes - not too shabby I'd say)

The main problem is that all the latest phones has to be so f...... superslim.
Who cares if the phone is one or two mm thicker if we get an ekstra day of battery life?
I don't wear tights and my pockets can take it

Uae the anker battery it is amazing

Is it really *that* good? I've heard both!

Delete?
Can we delete this thread?
The title is misleading and there is no new information, only a random allegation that the battery is not 'environment friendly' whatever that means in this context.

It's not THAT good, but it's definitely BETTER than stock.

PLEASE stop making this comparison. Just because the frequency off the processor is similar does not mean they will act at all similarly in regards to energy consumption. proof: That laptop is getting 3-4h off of a battery many times the capacity of our batteries and many times the volume of the entire sensation. The laptop was designed for 100-150 watts of power, while the average phone is designed for less than 5. Sense is ABSOLUTELY NOT built for the best performance, as many custom roms have proven, and there is absolutely no way that modern, high tech tiny phone-scale dual core processors would be similar to 2007-era computing hardware in any way except for the number of cores and frequency. Also: Frequency does not mean everything. it only measures how many times the processor cycles. The important number is instructions per cycle or instructions per second.

Buying the Nexus 5

Hi all I've come to a decision that buying the Nexus 5 is worth it, a perfect collection to my devices
The Snapdragon 800 Quad 2.3 got my attention and its pretty cheap
I would like to ask about the battery life and if there are any custom roms that improve it
Thanks alot

Hi,
For the battery life it will vary from each users, it depends on your usage and settings (screen brightness, synchro, GPS, etc...), for more details you can take a look here for example: Nexus 5 Battery Results. Some users have 7 hrs screen on time, others 3 hrs (plus the idle time to take in consideration) for example, like I said it depends of your use. If you are a gamer the battery life will not be the same as the user who use its phone only for SMS.
Again you will have different opinions (and people that claims that x rom or x kernel is the best for battery life, you'll have the same number of opinions as there are different roms / kernels and it will not help you more...), for some the battery life is great and for others it's terrible, etc..., I would say the average is a day for about 4 Hrs screen on time with "normal" (or "light" use, I mean not 1 hour of Dead Trigger) use. It will depend of what you will do with your phone?
The battery life is mainly on the user side, it's not x rom or y rom that will give you better or worse battery life (unless a big issue in the rom, but... or sometimes it's the Gapps that drain more than usual it's right). If you have a bad signal or a rogue app that give you a ton of wackelocks so higher battery drain, whatever the rom or the kernel you will use it will be always the same thing.
If you want improve your battery life, know what apps you have, how and what they do in background for example (to avoid wackeloks), you can underclock, etc...
Take a look here also about battery life and kernel: Nexus 5 Battery benchmarks.
And there is already a bunch of threads (and review) about battery life in the Q&A forum...

To add to what they said though, certain Kernels with certain Roms can HELP with battery life but it all boils down to how the user uses it. I can tell you that with my same usage on KitKat and Cyanogenmod 11 (CM11), I get better battery life out of CM11. I recorded about a 4 hour longer battery life on CM11 as opposed to default KitKat that comes on the device.
You should look into CM11, it's a cleaner, more effecient, more customizable version of KitKat.
Hope this helps!
Great job to Viking on explaining battery life/Roms

@viking37, I Saw on some reviews on the internet that it comes pre-throttled ( pre underclocked ) is this true

Underclocked, for the Nexus 5 , I never saw this, have you a link?
All Nexus 5 are clocked at max 2,26 Ghz, nothing less... It seems that there is different variants of the S800 (clocked at 2,4/2,5 Ghz) but the S800 in the Nexus 5 it's 2,26 Ghz (MSM8974AA).
Maybe you mean this: http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)#Snapdragon_800?

I have no issues with battery life ... I consistently get 14-20 hours of use with 3-5 hours of screen time or 2-3 hours of screen with 1-2 hours of voice.
Auto brightness, GPS on, nothing special.

Oh thank goodness, I saw some reviews saying it comes pre-throttled to save battery
Thanks

battery life is terrible but after some modification, it better a lot.

I get 24 hours and 5 to 6 screen time. Tweaked heavily with battery life in mind.
Its nearly as good as my Moto x.

Battery manufacturers/suppliers for smartphones ?

In smartphones today, we can easily get information on their CPUs/GPUs etc.
But the only thing they mention about the battery is its capacity.
is it possible that some batteries from particular manufacturers would have better charge retaining properties or overall lifetime ?
Is it known whether batteries of say Samsung/HTC/Moto/Asus phones are generally better or worse than others ?
Or it does not matter, and mostly depends on the CPU/GPU and how the software handles the consumption/wakelocks etc ?

Lenovo legion Y90 battery high Voltage issue!

Hi guys, I have got the Lenovo legion Y90 phone a few days ago and while checking the battery's condition though the Accubattery app, I have noticed that the battery voltage is very high ranging from 7.8V to above 8.2V when it's fully charged. As far as I know the normal voltage for the phone's lithium ion battery should range from 3.9V to 4.2V when fully charged and it could be very harmful to the battery life if it goes higher than that but what I got is actually double the normal voltage. The phone has got dual batteries but I have never had this high voltage reading with any other dual battery phones that I have had before this one. Can anyone advise on that please? Thanks

i have the same issue im not sure what to do on k50 gamig

Does the k50 gaming edition have dual batteries too? Now I am starting to believe that this is an issue with the Accubattery software itself when dealing with dual batteries. I think it might be reading each of the batteries alone and summing-up the 2 voltages like doubling it! Because the phone usually doesn't get hot even with the high voltage reading

I don't think so coz i have one plus 8t and the voltage is fine
Anyways i returned the phone coz it was also getting hot

Maybe its a failure with the phone if its getting too hot, about having the double Volts is expected as these phones are game made and need hgh voltage to avoid increase the amp(which leads to high temeperature). so yes the divided battery is expected to delivery more voltage, but this is not risk, its just planned to be so.
