what's your setup?

These "great battery life" threads always annoy me to no end. Not to take anything away from your good fortune, congrats to you, but after what seems like dedicating part of my life to trying to get even passable battery life out of this damn phone, I still can't make it through a full day, unless I refrain from using it for the most part. I'm really curious as to what the variable is from phone to phone that causes many to have poor battery life, and a few select others to get exactly the opposite. Anyway, again...congrats!

I've been trying to think of a way to normalize the battery usage measurement. Something we can all use to make sure we are comparing apples to apples. I am considering an app that would record usage stats compared to battery drain and then assign that to a value. Then one could say " I got 10 hours of batter with a usage coefficient of 23". And 23 would relate to a scale of usage. That way we could get a better idea of what battery life really is.

Im stock, with nothing syncing in the background,brightness all the way low. I think those are things that drain the majority of the battery. Don't use Apps that are constantly running in the background, like an application protection for example

I'm with you. I get abysmal battery life and I am not by any definition a power user. Texts, emails, some web browsing only. No streaming at all. My email apps are set to manual only, wifi and gps off almost all the time, certainly when not in use, LTE off, brightness set to automatic.
Yet I get barely a few hours before the battery is very low. I'm talking like 7-8 hours, a majority of which is spent with the phone on standby in an off state.

Thanks, display, syncing. Really will help with battery life is display brightness is all the way down, and no accounts syncing in the background. But Ofcourse some people want syncing and prefer the display to light up a room, it's all about preferences.

That's great, but I'm not sure I'd want to have to hit the refresh button repeatedly like some needy maniac cuz I know that's exactly what I'd do.....lol

Right now running humble at 1.4ghz and juice defender i am getting 2-3% battery drain per hour with medium/heavy usage. I was getting 8 hours without juice defender but now that it's working i can see this.phone getting over 18 hours. Screen is around 60% brightness.

There really isn't a reason for my phone to be syncing every hour, I'll just go into my gmail and press the refresh. I'll go into pulse and refresh so I can check my newsfeed. Wifi always on and always great signal, weaker signal means more battery drainage, vibration should be off as it really uses battery. I'll keep on thinking about new things and post them

Living out in the sticks with crummy service or in a building with crummy service can really effect battery life.
For example, where I work and where I live, I'm pretty sure I'm connected to the same cell tower, as I work and like a mile apart as the crow flies.
With that said, I work in a brick building with a metal roof, and my phone fights for signal all day, every day. It drains 15% per hour at idle. The same phone with the same usage at home sips less than 5%. At home I get great coverage.
I can promise you, that's one factor to consider. Another is setting the display to automatic brightness. I find that to be a battery killer. I don't know if its because its always sensing and calculating, or if its just not at the optimal brightness. Maybe a combo of both.
Setting it statically, even if its not the dimmest setting helps me.. I don't know why tho.
So anyway, location has a very large part of battery life.... even if you're not set to auto sync, your radios are still talking to the towers. With a bad signal, the phone will crank up the power to maintain a better signal... and that will destroy your battery... even more then auto sync.

I've tried cutting down the extras to the absolute basics and it really made no difference for me, or if it did it was too small to identify. The two things i'm definitely not willing to go without is push mail and a display that I can see. Having said that I don't really get that many emails and my display is generally set to ~20% (no auto) which is just adequate. I use Google Voice also, but when I uninstalled it for a couple days the drain remained.

Are you sure your body isn't storing large amounts of electricity and you actually recharge the phone as you're holding it in your hand? Do you live directly under high voltage transmission lines by chance? I've never overclocked, but using stock clock settings with any combo of every ROM/Kernel available, regardless of whether it's stripped or loaded, under medium to heavy use with the display set to 60% I would see a drop of anywhere from 20%-30%/hr. The only time I get 2-3% per hour is in standby with the phone untouched and no calls or Emails/Gvoice texts coming through. Personally, I think you were lucky and scored one of the rigged units they send out to reviewers. lol

I thought this too, and while I know it absolutely does make a difference in regard to the amount of power the phone transmits with, after a couple recent experiences in different places with 5 bar reception, one even having 4G, my battery drain problem seemed unchanged or very mildly improved (but still dreadful). At home I only get 3G, I lock it to CDMA so it doesn't search, but average around 2-3 bars. It's never in standby mode that I have an issue, it's in use that the battery level plummets, even when not transmitting data. If I didn't love the phone so much in every other way I would have Ebayed it and gotten something else by now, but the idea of parting with it makes me very sad. I've also considered getting the 2600 mah battery, but then I can't use a case. Dilemmas.

I don't know about you guys... but, whenever I am home.. im on wifi. I keep reading about people being at home and being in bad service areas or whatever. At this day and age doesn't everyone have a wifi router at home? The wifi radio uses signifigantly less power than the lte radio or cdma radio, even with great reception.

[Q] Battery life. SKYICS rc7.3 ~ 9 HRS 43 MIN max charge.

I've had my skyrocket for about a month now, and I've had horrible horrible battery life compared to all of you guys on here. I've tried reflashing, did the whole .3e recovery/ wipe/ fresh install tutorial that Seanz posted. (Amazing rom by the way.)
Nothing seems to work. I've calibrated my battery at least 4 different times. Oh, and for Seanz, You say your rom is 2.3.5, but in my settings it says 2.3.6. My brightness is all the way down, My data, bluetooth, gps, etc are ALL OFF! Only thing I keep on is wifi, ALWAYS. I've tried leaving my phone off the charger all night and locked to see if the drain was the same, and it is, If not just a tad less drain. I'm sorry if I didn't clarify this good enough, If someone could help me out I'd be glad to explain myself better!

Does your phone maintain a strong to moderate signal (both data and talk)? This includes the strength of your WiFi connection. I've noticed one of the biggest (if not the biggest) drain on this phone and most others comes when the phone is strugling for a decent connection. If you can, try this: put your phone in "Airplane" mode for 1 charging cycle. This means your phone won't even try to get a wireless connection of any type. To be safe, make sure the "WiFi" is off as well. See how long the battery lasts compared to it not being in "Airplane" mode. If it still sucks, you might need to see which app(s) are draining your phone. If it is noticably different, a weak signal might be the problem. Good luck.

He changed it only in text for certain apps that require Android 2.3.6, even though they'd work completely fine on 2.3.5. Somewhat an easy workaround. Also took some of the features from 2.3.6 in. It's still built from 2.3.5 though.

Thiiiis is probably your big issue. If you have any apps running in the background that use data, they can keep the wifi awake, which, in turn, never lets your phone sleep. If you go to Settings>Wireless and network>Wi-fi Settings>Menu Button>Wi-Fi Sleep Policy, and set it to "When screen is off," you'll be AMAZED at how much life it can save. I've noticed drastic differences when that setting is applied. As far as without it losing around 10-15% overnight to a mere 1%.

Thanks for your replies! I'll try you guys' ideas out now. I seem to lose about 1-3 percent every 10 minutes. I'll put it in airplane mode and try it for an hour.
Thank you Fortune! was wondering how to do this, You could have just solved my problem. I'll keep you guys informed! I'm amazed at this communities helpfulness. Thank you!

No prob!
Though, next time, if you have a question, should post it in the Q&A section of this forum. People tend to get a bit pissy about seeing Q's posted in other places, haha. Just giving a heads up!
Hope those fixes fix your battery life! That wifi sleep on has been key for my 30+ hr battery lives on SkyICS.

Seemed to not help :| Since I've done this, It's gone from 22% to 17% in about 15-20 minutes. No apps running, etc.

Try downloading CPU Spy from the market place and after awhile of letting it rest (about an hour or so), open it, refresh and check to see the CPU uses the "Deep Sleep" frequency at all and to see which frequencies it spends most of its time in.
Also wouldn't hurt to check Settings>About Phone>Battery Use to see what's using most of your battery life. Display, Android System, and Android OS typically hold the top 3 spots, so if anything is up there (or at a close 4th), that app could be what's bogging it down.

I downloaded CPU Spy and it seemed to already have data for it and it says 4% in deep sleep, 65% in 38 mhz, 5% in 810 MHz, and 1% in 1026 mhz, 17% in 1728 MHz

Alright, well so far so good. Shows it's at least getting some deep sleep and able to idle in low frequencies. Can't really get TOO well of a reading until it's done some time with it idling though.

Do not set wifi policy to screen off, keep it at always. this will keep your data using wifi when connected which is way less of a drain than the 4g radio. Basically with the screen off policy your phone will still use data, it will just come from cellular instead of wifi when screen is off.
Also get this

It will tell you what is running constantly and draining your battery.

Since he has his data off, turning off the wifi with screen off will benefit him greatly. It would be stuck on otherwise. Noted:

Ohwow.... That's....... Interesting, haha. If I notice my wifi is on for extended periods of time, my battery starts draining a bit faster than normal.
Might have some app in his background either keeping the phone awake or just hogging background data, keeping the wifi constantly active.

the real issue is when i actually stop being on wifi. when my phone uses data connection, mostly LTE because its everywhere around me, the battery life becomes miserable. I left the house for about 1 hour today, you can clearly see it on the graph. I should try to cut all connectivity and just allow the phone to sync every now and then, im sure ill be able to add another half a day at least to my already 1.5 days with wifi on all the time

Yeah, data is a KILLER. For me, it's usually wifi or nothing, unless I'm trying to send or receive an MMS, or need to quickly access the Internet, but I turn it back off as soon as I'm done, and I set my network to no LTE because it's not in my area.
Just take that as a note OP, lol.

[Q] Why does my battery drain so quickly?

I have been having really terrible battery on my AT&T HTC One X. I have had it for over a month now and it has not lasted nearly as long as some other users who posted their battery stats.
I have tried several things to try to improve my battery, including turning off auto-sync and turning off the mobile network for almost all day long. I have tried stock, CleanROM 3.1 DE, and Sick Sense HOXL (in which I used the CPU editor to set it to battery saver mode). I have been able to stretch the battery life out to last about an hour extra with the CPU editor, but still nowhere near where I have seen others at.
My battery lasts about 14-15 hours maximum and about 2 hours of screen usage at most, but that is rare. Some days my battery lasts less than 10 hours and not even an hour of screen time. On these days the battery will drop 3%-5% at a time, sometimes even 10% at a time.
I really don't want to go to AT&T and exchange the phone if I don't have to, but I do have a warranty on it. I get a high percentage of screen use and am not sure if that is normal. Could it possibly be that my screen is not completely turning off?
I am posting pics and a logcat file to help determine the issue. Any help would be greatly appreciated!

i swear this thread comes up every day

I have looked through the forum to see if there is anything related, but most seem to say their battery gets hot. I don't have that problem. Maybe it is just AT&T's LTE that drains the battery too quickly? I want to be sure there is nothing wrong with the phone though because some days it drops way too quickly. If I turn off the phone and turn it back on, I lost a tremendous amount of battery. It seems weird to me.

Chrome was murdering my battery before the update, now it still kills it. I did a full run with it install. I never opened it and it used 10% of my battery. Doesn't seem like that's your problem though. But just monitor for any rogue apps.

I've been using Bad ass Battery stats to keep track of stuff. Its been a bit helpful but like you, I get about 15 -20 hours before I have to consider plugging it in. Some weather Widgets really kick the crap out of the battery so keep that in mind.
Idk how people pull off these 24hrs+ times but I'm a bit jealous.

I have tried the APN method to switch off LTE, but the method is sort of unreliable as it drops the network too frequently. I tried it for a day, but the results were similar. Any other method or should I just test it for longer?

I used this method for a while as well, but yes, the network drops are annoying. The battery on the One X is very inconsistent. You may want to try swapping your unit to see if you can do better.
Another thing, there are issues with LTE when you drop/regain signal, it starts draining like crazy sometimes.

I'm still trying to determine if I've got a defective unit or not. My battery drains fast, but maybe I'm to blame?
From 100% charge, I'm down to 45% after 4.5 hours, 2 hours and 20 minutes of screen time.
54% screen
27% calls
7% chrome
6% maps (why the hell is this always running anyway?)
Any thoughts?

I really don't want to go to AT&T and exchange the phone if I don't have to, but I do have a warranty on it. I get a high percentage of screen use and am not sure if that is normal. Could it possibly be that my screen is not completely turning off?
I am posting pics and a logcat file to help determine the issue. Any help would be greatly appreciated!

There really are tons of threads talking about this, with battery temperature comments only being a fraction of those. search for the Battery Stats XL Edition thread. Not only does it have a ton of reports on good battery life, but TONS of info on how people achieve that and what they have found ot be helpful. There are numerous other threads you can find in a search. I have only seen one scenario where my battery drains remarkably quickly, and that's an issue with my corporate exchange email and is pretty sporadic (1 time every couple weeks, maybe slightly more).
Looks like you have one image in the OP that shows an extensive amount of WiFi-on time. that can really drain. screen brightness is another thing. I stay at 20% max,less if i can handle it. The app Brightness Toggle Widget is AWESOME for me...simple and makes it easy to keep phone at 20% (my normal level) but increase as ambient lighting dictates (like being outside). here are some more basic suggestions that i use to maintain easily a full day+ of battery. (running stock sense).
-disabled crapware (most att services, city id, google stuff I dont use, etc.)
-20% brightness most of the time
-wi-fi, GPS, BT off unless needed (LTE burns anyway!)
-syncing 1 gmail, 1 exchange account
-only running a couple of live widgets
-disabled live weather in pretty much every place possible as this can fry battery
-swipe away unused apps relatively frequently
these are mega-basic ideas but i've had no consistent battery problems and get great life. also, check your full charge voltage level using *#*#4636#*#* and confirm you are starting around 4187mV and have a healthy battery. it's also remarkably possible that you just got a phone with a poor battery/battery function. another thought is that i see you pulling some pretty low cell signal (only 1 bar LTE in one of those shots, 3 in a few others). That's not great and could kill more battery that you can easily tell. I'm in LTE and rarely see as little as 3 bars of service. if you are on the fringe of good signal that can really do you in. checked log file and nothing jumps out, but i'm not the most reliable source for interpreting that data. hope this helps in some way.

I have most bloatware disabled, at least everything that I was capable of disabling. My brightness is set to auto, I can try with it lower and see how that works (still not sure why my screen percentage shows to be so high, I have seen others with the phone and it stays much much lower like 20-30% and over 3 hours of use). I have auto-sync off and no live widgets running, I only use the sense clock/weather widget, but weather doesn't update unless I manually open it since auto-sync is off. I am also constantly swiping away unused apps and the only one that is ever really open is messaging because I use it more than anything else.
I really don't want to go swap my phone out unless there really is a problem with it, which is why I posted here. I need to find out of it is something hardware related, such as a defective battery or screen, rather than software related and capable of fixing.

Poor battery life on WiFi

Hi, can anyone help me solve this problem. I'm getting poor battery life from my Nexus S (stock 4.0.4) & android OS using a lot of battery. I've narrowed it down to WiFI - when I turn WiFi on, the battery depletes much faster than when I'm on 3G & android OS goes from ~7% to ~20% in battery stats. This is the opposite way around from what I would expect based on other posts, which say that WiFi uses less power than 3G. You can see the effect in the screenshot - for the entire time on this screenshot, I was at work with good 3G coverage & the WiFi point is right outside my office:

Any suggestions?

I agree with you, stock 4.0.4, Matr1x kernel (but I get same results with Air kernel too) and wifi always on = poor battery life.
My workaround is keeping it off and switching it on only just before an autosync or when opening browser/Gmail (I do that with Tasker)

When WiFi is in use what are you doing?

Essentially nothing. I checked the odd email, but for the most part the phone was in my pocket doing nothing.

have you got a background service that only runs on wifi?
also, in my experience, 3g only uses more battery when you're actually receiving data (e.g. browsing, data sync).
to me your battery stats don't look that bad, so my theory is that because you don't use your phone that much, anything that uses just a little bit of battery makes a big difference in battery use percentage.
but then again, I could be completely wrong...

Well one thign is for sure battery will always die faster on the network because most of the time if your in bad service areas it trys to fight for service therefore shi**ier battery life.
But @ Richstant do you disable mobile data manually like. For example because my NS4G is just deactivated on my Epic 4G i manually disable data and re enable when i use something so i save battery life.

I switched my sleep policy to while plugged in now. The difference with just switching the wifi on and off is really insane for me.

The way WiFi works while screen is off is hopeless on the Nexus S. I think it may be exagerrated because of the guzzling hardware as it seems no different on the GN or SGS3, though they dont drain nearly as much (i thought otherwise at first, unsure if it's on a phone-by-phone basis though). WiFi likes to stay on even if you set sleep policy otherwise - look at it funny and it will stay on and drain. This is something that i hope will improve in JB, but i doubt it. For now, best bet is set to Never (or plugged in, same effect) and switch it off manually if you won't be using it for long periods of time.
WiFi uses less power for large amounts of data and even browsing. It's faster, it doesn't need to send extra power and there is less thrashing to find the best signal. Data, however, is technically always there anyway as the radio is always powered, so if it only needs small amounts of constant data, it is often better for battery if you have good reception. This is one thing we i don't think we'll be worried about in newer phones, thankfully.

I'd forgotten about that setting, I'll try it now. In the past it's not worked for me though - the WiFi just stays on all the time no matter what.

Thanks for the info - sounds like it might be just the way this handset is :-( I don't remember it being this way under gingerbread, the WiFi turned off properly when it slept then, and battery life was much better.

I'd still disable the mobile data even regardless of how good the reception is it'll still save you more juice in the long end

You don't have any apps set to auto-upload or backup anything (e.g. Dropbox Camera Uploads, G+ Instant Upload) once it connects to Wifi do you?

Hmm, that option worked fine for me, when I unlock the phone, there's a 1-2 second delay before the wifi icon comes up, if I am not plugged in, that is.
I have latitude on all the time, I am suspecting that latitude is the one that causes my battery drain WHILE wifi is on, since there's just too much wifi hotspots around here, and if latitude is triggered everytime there's a new wifi hotspot discovered, then it will have a lot of updating to do. Using the sleep mode doesn't cut down the number of wakelocks (reported by BetteryBatteryStats) that those LocationServices triggers however, but battery life does seemed to be saved, especially on the days where I rarely use my phone.

I would look at this also. If there is an app that has some connection with wifi (i think this would be done through intents but i'm not very familiar), it may either keep wifi on or awaken it from sleep periodically (where it looks like other apps/features take over and continue using it instead of shutting it off immediately). Maps and something from Android OS or Android System seem to be main culprits if the battery page is to be believed. BetterBatteryStats can help, but haven't gained that much information in regard to wifi - though is priceless in most other areas.
Edit: Didn't see the last post (got distracted lol). That could be it. Note that in BBS you should also look at the number of wakeups, not just the time wakelocked. Obviously you can rack up a lot of wakeup attempts and still show only 1s of actual wakelock, but it adds up immensely from there - particularly when some other apps are triggered because they are notified wifi is temporarily "active" when it shouldn't be. Also, these are my experiences and not coding fact, so take them with a grain of salt and listen to those wiser than I

Well I'm pleased to say I got a serious improvement in battery life by setting wifi to off when not in use (except when charging). I tried that under 4.0.3 & it didn't work, but it seems to work correctly under 4.0.4.

wow, I didn't even know there was a "wifi on during sleep only when plugged in" option. I knew juice defender and other similar apps did something like that, but didn't know it was built into ICS (or CM9 )
thanked for the tip

Large variance in reported battery life due to overheating?

Like many others, I've scratched my head regarding why some seem to be able to get 7+ hours of screen on life while others get only around 3. I know the typical response is wakelocks but those SHOULDN'T affect screen on time much, when the CPU is already awake.
I have noticed that it seems that my device dies much faster when it gets hot, which makes sense, but I've never seen it affect a device to this extent. One time, I fully charged my battery and only got 3 hours SOT merely doing nonstop web browsing on WIFI without putting the device to sleep at all. Yesterday I even froze all apps except the stock ones after flashing PA gapps on Omnirom and my batter was worse than when I had 100+ apps and greenify. Usually I get 3-4 hours SOT a day of normal use on LTE with intermittent, cooler usage. When the device gets hot it also doesn't want to charge nearly as quickly either.
Therefore, I have a simple request: post your best or typical SOT and how often your device gets noticeably hot. I'd like to see if there's a trend between heat and SOT. Or at least vote in the poll. Both would be preferred.

lol, are you serious?
we see a large variance is battery life because we all use our devices completely differently. plus we all have different qualities of phone/data signals, we all use differing brightness for our screems(some auto some not), we all do differing things to set up our phones as we want.. do you want me to go on? and the temperatures, they vary throught the day, depending what you are doing, depending on the temperatures around you. sometimes they can get very hot, sometimes they stay cool with lighter use. i get 5.5-7h screen on time every day. my phone can see temperatures of 88C to 0C daily.

And disabling all apps to take the user setup out of the equation doesn't change things? Or the fact that I only got 3 hours SOT just web browsing? Sure, there's definitely variance involved but it seems like there's more with this device than I've ever seen before. Most devices I've used have been mostly consistent among users and don't have some people complaining about 2 hours versus 7 hours SOT in a short period.
It's easy to say it's environment variables or user error when you're getting 5+ hours every day but when you're someone who's been around the block with Android and phones in general and can't break the 4 hour mark ever, you start to wonder if there's more than initially meets the eye. I don't mean this to attack you, I'm just not sure what else yo do. I've tried undervolting, underclocking, keeping brightness down, greebifying (BBS looks fine), modified location settings, stayed on WiFi, turned off WiFi, removed apps, etc, and nothing helps SOT, only sleep drain.
The bottom line is, have you noticed your battery drains faster when it's hot or is it pretty constant? I'm just wondering if some devices, due to a lower PVS value or some other property of their chip, run hotter and drain more current doing the same tasks. Trying to eliminate the possibility.
P.S. Have you noticed the XDA app modifies or quotes the post above what you press? I have, as you can tell...

ive had g1, google ion, nexus one, nexus s, galaxy nexus, nexus 7, nexus 4, and the nexus 5 now. every one of them has/had great battery life. its the way i setup and use my devices. our use is a huge variable. every single person uses their device completely different. for example in setup and use, you use the crappy xda app, that uses a huge amount of battery, i use the browser, and never install those kinds of apps. many people have facebook installed, i uninstslled it more than 2.5 years ago, i use the browser for facebook. facebook is also a battery killer. i can go on and on. then theres the variances in phone and data signal. bad signals can get more battery drainage, terrible signals can be battery killers.
anyways, you said sleep drains. i bet you have a few badly behaving apps, or you are using the wrong kernel for your device. or, it could just be the way that you use your phone is the reason you don't see 4+ hours sot.

Fair enough. I know the XDA app is bad but didn't think it was so poorly coded that it's a battery hog. The site needs a mobile version IMO.
What do you mean by "you said sleep drains"? My device sleeps quite nicely, I just mentioned that because that's usually the battery life people complain about but that's not an issue here.
I'll try doing a full wipe and not just freeze all my apps and leave just the stock stuff for a couple of days and see if that makes a difference.
Yeah, I wish there was a way to quantify how much signal is killing your battery. Sure, there's the battery page in settings but more detail would be wonderful.
I've experimented with most every kernel but it never really made a difference. I mostly stick to Franco.
Either way, I'd still like to get some crowd data on what they see. Two devices with opposite results is hardly conclusive (even though all your devices have been good, that doesn't necessarily rule out the possibility that there's a bad batch of CPU's or batteries in some Nexus 5's, unlikely as that is.). Everything you've said is valid, but I want to entertain the notion that, while that may be the problem the vast majority of the time, there could be another cause. If I find a bad behaving app on my phone or I just have crappy signal, great, but more data is never a bad thing.

as you can see ill hit more than 4 hours sot, probably 5.5-6.5h sot. you notice my battery stats, heavy usage, but none of those silly apps eating battery, for me its mostly browser. yet earlier i was at 81C, because i was pushing my device. now cpu temps are around 44C.

That looks like it rules out CPU temperature then, if temperature caused heavy drain you should see a steep slope at that time. Did your battery ever get hot?

This is the first high-end smartphone I've owned that doesn't get hot at all. It'll get a little warm from time to time, but it's never anywhere near what I'd call "hot."
Samsung phones, on the other hand, get freaking HOT. My GS2 would get so hot at times that I could barely touch it, and my GS4 wasn't a whole lot better. My wife's GS3 will be blazing hot in its case when she's just been browsing the web or on Facebook. My N5 is never even close to as hot as Samsung phones have been in my experience.

Hmm, I dunno if I'd say it is painfully hot (thought when trying to wireless charge and use it it gets pretty bad) but certainly quite noticeable. What was the temp in degrees Celsius? I see 70s on the phone and 40s on the battery quite frequently.

Phones that get hot to the touch are actually doing a good job dissipating the heat. Though it may become uncomfortable to be absorbing some of that heat it does have to go somewhere.
Nexus 5 uses aggressive thermal throttling to keep the phone fairly cool and according to Anand has a heat spreader between the SoC and battery unlike the Nexus 4 which caused the two to heat up quicker.
The only thing that will stop me from getting over 4hrs SoT (3.5 - 5 based off usage) is if an application decides to keep the phone awake endlessly. I've seen it happen for Google Search and a few others randomly at times. Reboot or force stop fixes that up.

My nexus 5 battery also seems really crap, and the back gets hot very quickly. Everything else on this device is 100% perfect. Ive tried everything i possibly could (Different kernel, undervolting, lower cpu freq, change governors, low brightness, most connectivity settings off, ok google off, and many more battery saving aspects) yet i still can only get around 2-3 Hours sot with light usage (XDA, web browsing, social media). Is my device somewhat faulty? Or is it supposed to be like this? And normally when i play games, it drains at a speed of a percent per 40-60 seconds.
And please dont go about bashing me, im just a bit curious on how people get around 6 hours sot.

I haven't really had to do this on this phone, but I used to chase Screen on battery drain issues with Cool Tool from the play store. It floats a highly configurable window on the screen that lets you monitor a lot of system parameters including current draw - which is probably what you are most interested in here. I think you can also monitor the temp of the device, the cpu utilization, etc., etc. This lets you play with different settings and what not and get more immediate feedback as to what is happening with your device. In the screenshot, I configured the floating window only to show current draw...should be the pink 182 mA.

Thanks for that link but am I right in assuming most of it's functionality won't work correctly in KitKat? That has been reported with most battery or CPU monitoring apps so far.
I've been looking for something to show me current draw on stock but have only had battery widgets show me the current battery voltage which I don't understand the significance of. Starts at 4300mV when 100% and drops to about 3900mV when nearing empty.
