Of course with custom kernel, but my Nexus 4 with custom kernel only able to get 3-3.5hours SOT.

Not all phones are made equally? Even on nexus 4 some people can hit 5 or 6 hour SOT if you look at those in XDA. I'm pretty sure nexus 5 will not be a huge improvement over nexus 4 in battery department unless you're lucky. I came from a galaxy nexus --> one x --> nexus 4 so far all 3 more or less same performance in the battery department.

I remember someone here post a 7hours SOT of his Nexus 4 with CustomKernel and undervolt it something like that.

yes, undervolt and underclock is great start to have high SOT. next, disable unused services. use minimal screen brightness as well.

I think it's cowwithgun. he did it with stock ROM and self-compiled kernel.

Don't know what the fuss is all about SOT? Many do not even know when the SOT is recalibrated. If you continously recharge the phone true out the day without fully charging it the SOT will not reset, so how accurate and your claim of SOT is?

I believe that "Many" you referring to doesn't include cowithgun

He knows android very well. Released ROMs and Kernels for Galaxy W. Then he tweaked the Nexus 4 kernel for his personal use. I don't think it's 7 hours. Should be 6 hours something on his Nexus 4.

His claim is 100% trustworthy. Don't mess with him

Actually just 6 hours. I tried kitkat stock kernel for a week. Baterry life really run out fast compared when I undervolt. Now running on self compiled Kitkat kernel.



Ya, whats the fuss about SOT. I suppose if you want to cheat on the SOT and try to impress someone, you can do that. Photoshop works quite well too. ;-)

He he. Thanks for the shout out.

just messing around.

No plan for developing ROM/Kernel for N4?

malas!

How low did you UC and UV?Mind sharing your kernel

Max record on SOT for me is just 4 ¹/² hour.

But not really fun doing it because have to make the phone somewhat less smart to archive it.

For best battery phone i would go for LG G2.Seems good from consumers review.

i did mine by changing voltage table in this file:

You can do the same using custom kernel by many developers that support User Volt Control.

Sorry guys, I didn't know there was a sport for SOT hehe. But I don't think I will enjoy it.

it seems that N5 have far more better battery than N4

Last I checked it was $400 cheaper than n5. You can buy like 8 powerbanks
with that much.

it depends. first, n5 has 2300mAh vs n4 has 2100mAh. naturally, it is 9% better. secondly, the Snapdragon 800's sensor cores help to offload CPU.

in theory, you should see noticeable improvement in battery if you phone is mostly low usage. ie: talk time benchmark:

n4: 14:17
n5: 16:40

but in full power usage, where all 4 cores will be used, little difference. ie: gaming, browsing:

n4: 4:34
n5: 4:46

in mix usage, you should still see improvement. but far better? i prefer the term incremental improvement.

Seriously... It makes me wonder... Whether is all other manufacturer too good at managing battery/power management or is Google too bad at it? No optimization at all??

Nexus 4 has 2100 mAh (Erm... Same as S3???) Nexus 5 has even bigger, at 2300 mAh. But looking at gsmarena's battery test, just as benchmark... S3 is better than both Nexus 4 and Nexus 5, losing out only in talk time.

Endurance rating, S3 50 hours N4 32 hours N5 40 hours despite bigger battery.

Sometimes... It just make me think that Google never care about optimization for battery. Same battery capacity, both running on Android and Google is the core of android yet getting outperformed in this particular sector.

Maybe next iteration of Android, they emphasize on this? Hope so

Well I guess this is where they cut corners to make the price more affordable. Nexus devices always using latest tech in terms of proc, ram etc. I remember G.Nexus was the first one with 720p screen

battery life, amoled is better. brightness, i prefer IPS. for longevity AMOLED color washed out faster than IPS (cannot remember the source)

Damn... i break my nexus 4 front glass + touch digitizer.
where to get it cheap... or rather let it inside box...
