[AT&T LG Optimus G] OMGMatrix:
I apologize, but that is not the issue I highlighted.

I can use root apps fine, it's just that the apps report that they're not getting SU rights, when in fact they are. For example, Adaway will say that copying the hosts file failed, but when I close the app & reboot the phone, I find the the hosts file Was in fact copied, and the app is simply reporting that it isn't working.
[AT&T LG Optimus G] MiZrY:
It sounded like the problem I am having.

Though I just figured out that it is not the ROM, it's the OC kernel. Everything in the ROM works fine unless I use the OC kernel. Does the same thing on cm10.2.
[AT&T LG Optimus G] OMGMatrix:
Sounds right, I wasn't using the OC kernel.
[AT&T LG Optimus G] TnG2903:
Hi,

I'm using xposed core module, with bootmanager. Which module cause you problem? I'll try it out for you
[AT&T LG Optimus G] C2fifield:
Um I tried gravitybox and a couple other all in one tweak packages. I guess I'm not surprised they don't work since they're meant for aosp, but I was trying to get some more features since I'm used to carbon.
[AT&T LG Optimus G] TnG2903:
Hi,

I've tried gravitybox too, without any problem :D. Nothing force close for me. I'm using the kernel in this rom, not the OC one.

But strange thing happen when I tried to enable Multicore Power Saving option in trickster kernel mod. When set to 1, once in a while, I get kernel crashed, the screen went black, with DemiGod Kernel Crash handler appear. Anyone seen this problem?
[AT&T LG Optimus G] C2fifield:
Hm, I was using the oc kernel so maybe that did it... Thanks for the info!
[AT&T LG Optimus G] iamtha1:
The 10/28 build says no changes but is 10mb smaller.....?
[AT&T LG Optimus G] NHS2008:
I installed this rom. Its awesome, expect My SD Card wont mount! Its EXFAT 64 GB. Do I need to make it FAT 32??
[AT&T LG Optimus G] TnG2903:
They made changes in toolchain and some optimise, details here

[AT&T LG Optimus G] axeman007:
Hi snow, are you working on porting G2 ROM to LGOG??
[AT&T LG Optimus G] aznracer62:
Are you guys getting locks on your gps?
[AT&T LG Optimus G] TnG2903:
Yes, do you have problem with GPS? Is it something like "the gps icon appear with a small (x) on it" ? If so, you can try these step, I've followed the tutorial in xda and fixed it, but don't remember the link :D

- Flash ICS modem. Start up. Don't worry if the gps still fail.

- Flash slickv2 rom. (the tutorial I follow said that this is the only room can fix this problem)

- Boot up slickv2, gps still broke. It's ok, but try to active (I mean using) GPS from something like GPS status or Maps

- Flash JB modem, clear cache. Reboot, confirm that the GPS is working (yup, magic :D)

- Flash room as your choice, but remember not to format the system partition using recovery, let the room do it themselves.

(I was using CWM recovery, I heard some one said that this is the only thing don't broke the GPS, but who know, you can use others as your choice)

If it doesn't fix, PM me and I will try to help
[AT&T LG Optimus G] aznracer62:
Thank you. I did something similar to this but with the stock Rom. I'll try your method and see if it will work for me.
[AT&T LG Optimus G] plaster:
Installed the Nov 1 nightly last night and I've been putting it through it's paces. So fare it's been 100% stable and the performance is nice. I'm now throwing heavy games at it to see how it holds up. So far so good.
[AT&T LG Optimus G] itsallhell:
This rom is so awesome. Boot up time is amazingly fast and everything works as expected. Great job devs.
[AT&T LG Optimus G] optimusv45:
Sometimes system just freezes while typing, then unfreeze in a couple of seconds.
[Nexus 5 General] ashkan_mc:
Besides all these, I believe android 4.4 is more battery friendly than 4.3
[Nexus 5 General] Lewythefly:
Can I borrow your crystal ball? I need to get tonights lotto numbers
[Nexus 5 General] hello00:
ha
[Nexus 5 General] Peek-A-Boogie:
Nice thread, i can see that being true. Besides, like it was said above, based on the kitkat video; android 4.4 is said to be an improved project "butter". I expect the 2.300mh battery life to be enough for the phone.I can go as far as to say 3000mh is over doing it and pointless. :silly:
[Nexus 5 General] topgeardave:
Does anyone know how much screen on time the HTC One gets? I can't find any screenshots in the One forums with the stock kernel and stock ROM.
[Nexus 5 General] shook187:
I was getting no more then 3.5 hours in a good day but far less on the regular.
[Nexus 5 General] Turbotab:
Of course being a Nexus, we are guaranteed excellent dev support, a custom kernel that allows undervolting will boost battery life, even the Nexus 4 isn't bad with a moderate undervolt.
[Nexus 5 General] xXxG0dzRAgexXx:
Personally for me on stock ROM and kernel I got no less than 4+ hours screen on time. Going up to 6 hours some days.
[Nexus 5 General] topgeardave:
Wicked! Is that with a combination of 4G/wifi with medium brightness?
[Nexus 5 General] ashkan_mc:
4 8 15 16 23 42

:D
[Nexus 5 General] 7TimesCursed:
Wow.. To put that in perspective, the S800 uses the same voltage at 2.3ghz that my N4 uses at 810mhz!
[Nexus 5 General] ricey1986:
Wouldn't we all be devastated if these actually turn out to be the correct lotto numbers haha
[Nexus 5 General] BoneXDA:
It looks like low power tasks and standby is best in class on the SD800. I'd image however that 100% load would brutalize the battery, although it's still nothing compared to the carpet bombing by the Adreno 330, which according to Erica, destroys the G2's 3000mAh playing NFS in 90 minutes. That's just crazy!
[Nexus 5 General] topgeardave:
Does that mean by underclocking to around 1.5ghz we will get substantial battery savings?
[Nexus 5 General] ashirviskas:
Well, we could downclock our N5s to 1.7 GHz, enjoy good battery and then when the time comes when we need more power we could revert it back to 2.3 GHz. After a few years maybe :cyclops:
[Nexus 5 General] The Gingerbread Man:
That's quite an amusing thought under clocking to 1.7ghz for battery savings, my gnex runs at 1.2ghz which is fine, my 2012 n7 at 1.3 lol
[Nexus 5 General] topgeardave:
Haha, same here. My sensation is on 1.2ghz at the moment and it's fine. Only bottleneck is 768mb of RAM which means I have to kill many apps. Once I get the phone I'm going to compare battery life on 1.5ghz (same as N4) and 2.3 and see the difference in battery life. I might try an extreme test and downclock them to 1ghz/1.2ghz for lolz to share with everyone. The main thing I've learnt which determines battery life is mpdecision. I'm going to mess about with it till I can get the best battery life
[Nexus 5 General] Whyzor:
Interesting, one thing I want to mention you're assuming the 'race-to-idle' condition for the CPU. And in web browsing, may not apply since the bottleneck is likely the network that it has to wait for, so even though the CPU may finish local tasks faster, it may spend extra (wasted) cycles waiting for the network to fetch the data. Or even RAM which are slower than local CPU cache.

Also some brief googling for the N4's S4 Pro (8064) chip voltage tables came up with something like this, for more accurate comparison

[Nexus 5 General] The Gingerbread Man:
Also the much lower voltages will really help save the power to if you saw that earlier in the thread which also should help not make these things heat up so much.
[Nexus 5 General] ryude:
Wouldn't the bigger screen and LTE modem actually use more power than the N4 though? Not to mention 1080p vs 720p.
[Nexus 5 General] jonup:
If you don't get these right, it will say a lot about your statement about 4.4 efficiency.

[MENTION=225651]op[/MENTION] SD800 is definitely a lot more efficient beast. That said lower voltage does not necessarily mean lower power draw (wattage). Judging by what I have seen from G2, sot on N5 should be right about 7-8h. This is way to much time to spend looking at the phone everyday. I would be among a extremely small minority that would have preferred smaller battery to reduce the phone's weight and bulk. 5h sot is more than enough to get you through the day. Let's be honest, 95%+ of use have the opportunity to charge our phones at least once a day, every day. More/bigger is actually not always better. Looking at you Samsung Mega 6.3.
[Nexus 5 General] FlexiPack:
I was wondering about this too.
[Nexus 5 General] ryude:
After all, the CPU has never really been where the power was being used anyway. The screen has always been the biggest draw on the battery and this one is bigger while also denser in pixels.
[Nexus 5 General] Turbotab:
With Qualcomm SoCS, you have to select voltage tables from the same PVS (binning), as they is quite a variance between them, but the S4 Pro is quite a bit worse then a Snapdragon 600, probably down to early 28nm immaturity.

Even if the DOM is waiting on network to fetch data, a S800 will scale its CPU via DVFS, and use less voltage than an S4 Pro in the same conditions, once the data is downloaded the S800 will render the page faster, making the user happier, and then either allow the CPU to power-gate cores or simply scale back the frequency via DVFS. Either way, the S800 will feel more responsive, and irrespective of whether the CPU is idle or at max utilisation, the beauty is that it'll need fewer volts than a N4. The only problem is price, surely Google can't offer all this phone for $299 / £199:fingers-crossed:
[Nexus 5 General] Zahidow:
performance should be very good
[Nexus 5 General] Turbotab:
That's why I made my initial comparison with a HTC One, it has a similarly large 1080P screen and LTE, as the leaked Nexus 5 specs, and the battery size is the same.
[Nexus 5 General] topgeardave:
Judging by the G2's 5.2" panel, screen on time isn't that bad as it'll be just a 5" version as that. And LTE is now built into the SoC so it idles much more quickly than before. That's why when the screen is off battery drain isn't that bad. Difference between dchspa+42 and LTE is negligible in terms of power input. And the 1080p vs 720p is negligible because the GPU is more powerful yet more efficient on battery when idling. Only thing that will kill battery on the N5 are poor apps with wakelocks and setting display brightness higher than 50%
[Nexus 5 General] ryude:
I mean I have a Sony Xperia ZL with a 5" 1080p screen and same CPU/GPU as the N4 with a 2370mAh battery. It lasts a whole day for me, so I'm sure the N5 will do just as well.
[Nexus 5 General] Whyzor:
Here's a more accurate comparison based on real battery tests done by GSMArena on Nexus 4 and LG G2. The N5 should have a slightly thriftier LCD panel than G2's 5.2", so the projected battery life may even be better.

yes!!! see,! just wait for battery testes! i forgot what i was going to say:(
[Nexus 5 General] topgeardave:
Could you check how much screen on time you receive at the end of the day when you're low on battery? You should technically get 4-5hours onscreen minimum on medium brightness
[Nexus 5 General] supersain08:

Have a look at GSM arena's GS4, HTC ONE, and their Google play edition battery tests. The skinned version of the phones get better battery life even though they have more bloat.
[Nexus 5 General] ryude:
I use auto brightness and I work nights so I'm sure it won't match up with others.

[Nexus 5 General] Lewythefly:
Ewe .............. this is why I am happy with the thickness of my N4 and the roughly 4hrs SOT which will last a full day no problem

As long as the N5 gets about 4hrs SOT I'll be ok with it, anymore and I'll be a happy camper
[Nexus 5 General] antifocus:
Just want to say lower voltage doesn't necesarilly mean less power consumption, you have to take current into consideration.
[Nexus 5 General] haris.herry:
WHAT ABOUT THE andreno 330 how much it takes power wise compared to 320.
[Nexus 5 General] topgeardave:
Since lower voltages are being applied, you can easily infer that lower current is being used. Basic physics states to drive higher currents through fixed resistors and capacitors you need higher voltages.
[Nexus 5 General] tech_head:
Please don't confuse voltage with current.

The voltage at which a part runs does not equal power. Power (Watts) = V (voltage) x I (current).

Low voltage threshold processes are used for high performance and high voltage threshold processes are used for low power.

LVT processes have higher leakage and consume more power not less than the HVT process.

So you have it all wrong. You can draw no conclusion based on the operating voltage, except that the HPM will potentially have higher leakage and therefor a possible higher current draw with all things being equal. It also has a higher clock frequency potential.

The S800 has different power management than the S600 besides the process being different.

Qualcomm has to switch to HPM to get the performance because LPM was too slow to run at > 2GHz.

Anyway.......
[Nexus 5 General] Turbotab:
Firstly, TSMC's HPM process, according to their data allows a mix of both high & low performance transistors on the same die, they quote a leakage similar to the LP process used in the S4 Pro / S600. That being the case, voltage is still a useful parameter, especially as power increases with the square of voltage

P = CFV^2 (where P = power, C = capacitance, V = voltage, F = frequency). I took this from some Intel documentation. Ultimately, the proof is in pudding, and I await battery life testing from a reputable site, such as Anandtech.
[Nexus 5 General] tech_head:
Yes, they do have a mix of high and low performance transistors. Not the same a the LPM as the process parameters are different.

I've taped out a chip with the LPM process and we looked at the HPM process.

Frequency scaling/throttling is where the S800 will get you a power reduction, if it can scale better and faster based on demand.

You will not get the power reduction in process changes as you would going from a 40nm process to a 28nm process.

You are also in what could be considered a leaky process, and no matter what TSMC quotes HPM has higher leakage in the real world than LPM.

You can control it with voltage islands and shutting the voltage off to parts of the die, but it's there.

Anyway, I don't think it matters a lot.

When one is at work, plug the phone in.

When one is in the car, plug the phone in.

I have a GS4 that I recently purchased. Would love to have an S800 based phone but it doesn't look like any soon to be released beats fit my parameters.

1. I'm on Verizon (not leaving due to some special incentives) so no Nexus 5 for me.

2. The LG G2 is different for Verizon so it might as well have a different name. No cases and such.

3. None so far have removable storage LG G2, Nexus 5.

Maybe the Galaxy S5 will have a S800 and removable storage.

I can get past the non-removable battery.

before the S4, my last three phones had non-removable batteries.

I can't get past the fixed storage and only 32GB of it.

Anyway, let's see what this beast does when it come out!!!
[Nexus 5 General] ajftl:
My z1 battery is pretty awesome. 3000 tho. last all day heavy use.
[Nexus 5 General] nidhish91:
Yes we were talking about z1 in this whole thead.
[Nexus 5 General] M-Dawg:
Agreed. After a day's usage the note 2 (for example) might have about 50% remaining, so there's really no need to charge it...but ill be damned if I'm not going to charge it overnight. Until they make a huge leap forward in stock battery life (no extended batteries) that reaches about 4-5 days easy, people are mostly going to be charging it overnight any ways. That's my opinion anyway.
[Nexus 5 General] topgeardave:
Most people just want a phone that will last 24hours with 7-8 hours onscreen with 3G on constantly. After getting the N4 to get to 7 hours onscreen time by underclocking to 1ghz I'm sure the N5 can pull off the same at 1ghz as it is more efficient.
[Nexus 5 General] Cuzz1369:
You "lost"
[Nexus 5 General] lolcopter:
note 3 probably isn't a fair comparison given it's 3200 mAh, but completely anecdotal evidence-- my buddy has the note 3 and he said it's basically impassible to kill the battery. full day of heavy use and he's still close to 60% end of day

snapdragon800 seems very battery friendly all things considered

TAKE MY MONEY!!!!!!!!!!!!!!!!!!!!!!!!
[Nexus 5 General] mo976:
Dont know why the N4 gets so much flack sure its not a Razr Max but I (ok my wife) get 4+ hours screen time with auto brightness and around an hour and a half talk time on a charge with CM10.2! If your the kind of person who spends his days far from an office or car and just has to spend lots of time on the phone maybe you need a power pack like this http://www.amazon.com/20000mAh-Ultr...EOYS/ref=aag_m_pw_dp?ie=UTF8&m=A294P4X9EWVXLJ ok there are cheaper smaller ones but you get the point.
[Nexus 5 General] glitchhawk:
My main concern is getting through a day with bluetooth on. I have a pebble watch, and my car links to my phone as well. :cyclops:
[Nexus 5 General] The Gingerbread Man:
It will have at least Bluetooth 4.0 which is the low energy version I beleive
[Nexus 5 General] Invalid_GR:
S800 may be more efficient but you should take in consideration that in addition to the befier GPU the phone would have a larger,denser,brighter and probably more demanding display than the N4 to power.
[Nexus 5 General] talz13:
Does the low-energy only apply when connecting to BT 4.0 devices? If I connect to my BT 2.1 headset, it will still probably use BT 2.1 power amounts?
[Nexus 5 General] donalgodon:
That's pretty much what happens. The cycle takes one step forward and two steps back. We have a more efficient architecture, so let's strap on some feature that 90% of users won't use or notice which will suck out all that battery savings. Samsung's Toucwiz is the worst of the bunch in the major Android players.

Every year, we are told that this year's version of Android is going to be the Holy Grail of platform unification and battery life, and today, less than 0.5% of users are running 4.3.x to date.
[Nexus 5 General] The Gingerbread Man:
That's because carriers and phone manufactures drag their feet with updates because of their skins. It has always been simple, want to be first inline for update to android os? Buy a nexus
[Nexus 5 General] cnote1287:
stogntern time

The display argument is a non issue to me. I usually run my phones at 10-20% brightness all the time, and that's fine for me. The only time it goes up is when I'm outside, and I usually only set it to 50% then anyways. If the screen is alot brighter than the N4, maybe I can get away with 5-10% or 30% outdoors then.

In any case, there are workarounds.
[Nexus 5 General] The Gingerbread Man:
Or if the exploit is exposed increase each colour mulitplyer which will increase colour and vibrancy instead of increasing the level of back light which in most cases should use the most battery. To my knowledge increasing the colour strength has minimal battery drain
[Nexus 5 General] Shan89:
I agree with you , take for example my one , I get average 6/7 hrs screen time with moderate usage , I've undervoled my one -195 that's even lower then what is s800 running but my battery barely got better , I've maybe got 15/20 mins extra screen time which is invisible , what was visible is the temperatures , phone went cooler for average -3c whatever I do , normal usage @1.7 31/33c , gaming 38/39c , before uv I was @ normal usage 35/36c and gaming up to 42 tops.

+ let's not forget n5 is fhd + larger screen + higher ppi , I would be happy if n5 matches n4 screen time , hopefully it will , if anything gonna boost battery for n5 it's gonna be 4.4 imo.

Software and drivers showed us to be the best thing that can increase battery life.
[Nexus 5 General] Invalid_GR:
I just don't get it when some people here say that's ok if the battery is small,you can always underclock,keep screen brightness at 10%,use your phone less etc,etc.

What's the point of getting a device with a 2.3GHz processor if you are going to underclock it?

What's the point of having a great bright screen if you have to use it at lower brightness just to get you through the day.

And generally speaking what's the point of having a smartphone if you have to do all these and also turn sync off,greenify apps,stop watching videos,stop playing games,stop browsing the web and have 2-3 chargers in every place you go just to keep your device running?

Smartphones were made for "power" users and should last at least a day of ''heavy'' usage..
[Nexus 5 General] turdbogls:
"should" and "do" are 2 totally different things. until they DO last a full day of heavy usage, people are just going to have to do what they need to do to get through a day.

i personally have been able to live with a verizon Galaxy nexus for 2 years. the thing barely lasts me 8 hours on wifi with less than an hour screen on time. its not that great...but you know what, i get through the day with that.

so people complaining about the N4 having terrible battery life.....get real! :)

this N5 is going to be amazing to me.

and I personally thought the whole battery life thing got blown out of perportion when it was first announced as having a 2300 mah battery. that is ALREADY a 25% size increase....then throw the newer radio technology and newer processors....this thing will feel like a tablet to me :)
[Nexus 5 General] rfvreynoso:
I'm on the same boat with you on the galaxy nexus on vz. Horrific battery life so I have a charger just about everywhere but the restrooms. Too bad I may have to go to the 2nd best phone around on the lg g2 since everything points to the nexus 5 not being on vz.

Battery life of anything over 1 hr and 45 mins is a huge win for me.
