What sort of battery drain do you currently get on standby? Can you tell me the reading in ma from CurrentWidget? If it's 3-5 ma with mobile network/wifi/bluetooth etc on and 2ma in airplane mode then you're fine,but if it's higher it can definitely be improved.
If you don't plan to use mobile internet connection then disable 3G and turn 2G mode only. Turn off as many widgets as you only can, disable Location Service and auto sync. Install apps on phone memory only.
Also Dorimanx kernel is a hell of battery drainer, use another one like stable Tytungs etc.
Use dynamic/powersave CPU governors or use CPU speed profile apps like SetCPU and make several profiles for it.
This is only a few of tips we can give here.

im getting between 10 to 15 ma with 2g on and sync all the rest is off, and im using smartassv2 governator i dont know if this can be improved .. and i really like dorimanx kernel becouse it feels faster then tytung and it gets less hotter becouse right now is really hot these days and i nearly cant use the phone with tytung kernel becouse it gets crazy hot :O

Well the apps I use to reduce my battery drain are JuiceDefender and SetCPU. Set the profiles to be 245-576 Mhz when screen is off (smartassv2) and whatever else you like when screen is on. I never had any overheating problem with Tytung's kernel though. It was the most stable and just as fast as Dorimanx's kernel IMO. Still, using ICS now so I can't really judge about the newest versions of each of them.

I think his kernel is the same in battery drain over any of them. Ive tried them all. If anything, seader_r9 was the best and it was only a small improvement. My battery life is pretty short, but im a HEAVY user. Constant web browsing, constant text messaging contant GPS. And it lasts for the majority of the day. Now i have an .sh script which helps tweak the smartassV2 settings. I get about 110-200ma drain when doing simple web browsing or replying to a text.
One must also keep in mind that the ROM has a major part in battery drain as well. I heard from many users on here that MIUI has the best battery life. All in all i think any kernel you choose will have reletively (i spelled that wrong -.- its still early ) the same battery drain. It really comes down to the amount of use your phone has. But as stated before, turning off data greatly saves the battery as does turning down the screen brightness, fyi, automatic brightness sucks battery life too. Plus android does a horrible job polling the light sensor -.- it shouldnt take an average of 3 seconds to get the changed light value..
Theres not much 'tweaking' you can do to give you like an hour extra of battery life. Our batteries are only 1350mah batteries and thats really small for such a huge screen. My Touch Pro 2 has a 1500 and a much smaller screen. There are a lot of good aftermarket batteries on ebay that you could get which would extend your running time.
thanks guys, im gonna give a shot to tytung kernel, but im also gonna take a look to the aftermarket baterys
Typhoon rom support undervolt so if your phone is gettin' hot I suggest you to tweak the voltages as explained to original thread first page, it makes a big difference compared to stock.

Good advice here. There's a lot you can do (as already advised) but always some performance tradeoffs. The standard HD2 battery is only 1230 mA... not 1350. Smartassv2 in DM's kernels is excellent for performance and settles down nicely in standby - but it will pull-on your battery when used. There's no substitute for keeping a few extra charged batteries around (when you need them), along with AC & DC chargers + cable, in a small carrying case.

You don't need to use dorimanx's latest kernels, his stable kernels in fact do a better job at not overheating and have only 2ma drain on standby. I know 5.9, 6.3, 6.4d, and 6.9A (ics hwa) give a great battery life.

Wow, in standby im on average around 7-3mA with the occational spikes when receiving texts or messages over wifi. And when on data its about the same, just not as often in the 3ma range.

Which apps are running in the background? People constantly say that task killers make no difference yet whenever I've opened something and haven't killed it I get a higher battery drain than normal.
Also, use JuiceDefender and SetCPU to lower the drain.
...Who seems to be getting worse battery life since I've rooted and installed CM10 and Franco Kernel than stock.
Before with stock I was only losing about 1% every two hours on standby (sometimes even better I've no idea how)
Now I'm losing about 3% an hour on standby and also about 30% an hour screen time with just basic browsing (Screen brightness set to auto).
Also Media server is hammering my battery. Like I lost 3% battery in 15 mins without the screen on just playing music (not streaming) is that normal, I've come from an iphone 4s which didn't lose that in an hour :S
have i flashed it badly is there something else maybe i should try or are these stats about right ????
thanks guys
That's just the way it is just custom roms. When flashing, put your head between your legs and pray for the best. You can spend hours trying to figure out what's gone wrong, but you might never get an answer.
You can try underclocking your N4. Currently my dual-core Snapdragon S3 T-Mo Galaxy S2 is underclocked to 810MHz from 1.5GHz and performance is still great. I'm guessing you can UC your N4 to at least 1.2-1GHz and performance will still be great because of the quad-core Snapdragon S4 Pro CPU. Also, what governor and i/o are you using?

Hi Gents
Thanks for the reply, yeah it does seem a bit of a hit and miss kinda situation, I'm not masively bothered, im hoping eventually someone will stumple across a fix for the way the screen murders the battery life but im not holding my breath. Still love the phone, really getting used to it now, have tried (and failed) many times to switch to android, must be honest, this is the closest I've come so far to waving bye bye to ios, android is really really fantastic as an os, it's also super pretty to look at these days, stock apps like contacts, calender and the phone app itself are beautiful.
Let the phone and battery have several cycles, it will improve, eventually
thanks mate !!

Under clocking your phone isn't a viable situation. It's a phone, what's the point in it if you're not going to use it to your fullest when my phone lasts through the whole day going from 384-1500?
Some battery tips for op:
- download better battery stats (Google it for a xda version) use this to debug wakelock and ensure your phone is deep sleeping under cpu states. You can also use cpu spy to check cpu stats. Better battery stats is a must need.
- disable Google latitude in maps. Disable the automatic reporting and any other checked marks
- disable Google now cards that you have no use for
- disable gps (some apps use gps and drains battery when it keeps using gps when it isn't necessary)
- ensure your governor is interactive and on latest version of Franco (r20 is very good)

Highly advise doing that. Other kernels are way more optimized whereas CM is focused on the ROM itself and not optimizing the stock kernel.
I believe CM10 uses stock Google kernel anyways (could be wrong).
Use Franco Kernel or anybody elses kernel that you choose to.
Mine definitely improved after rooting and flashing custom ROM. Battery life when I was still stock was horrible.

Hello,
I have done nothing to my Nexus 4 so far but I recently noticed that the battery isn't that good. I heard that the Franco Kernel might give more battery life. I don't play any games I just use it for texting, surfing and listening to music. Is the Franco Kernel good for my usage then or would you suggest another kernel?
I found the thread where I can download the Kernel but what is OP, Milestone and Nightlies? How do I flash this Kernel? Do I have to root? I couldn't find any HOW TOs.
Hope you guys can help!
Thanks!

Yes you will need to unlock your bootloader, install a custom recovery, and root. Then you download the franco kernel zip and flash it through recovery.
OP = original post
Nightly = means the latest build (they are compiled every night, and may have bugs)
Milestone = usually means a complete version (stable releases)
Milestone = stable version
Nightly = newer version may contain bugs
U first need to root your device and download the Franco kernel zip and place it in your extSdCard. Once rooted goto recovery (volume up + home + power) select install zip from external card. Browse to file select then install... And enjoy...
Make sure u know wot you doing. Read first n read alot before any action else you may brick your device.
:*: Neebi :*:
also you can buy the app and it install the flash by itself,
i guess you still need to root
since you don´t game it`s weird to have bad battery, try greenify

Your apps will make the biggest difference. Stop apps causing wake locks such as Facebook and anything with auto refreshing/push alerts.
The biggest benefit for me of using Franco is adjusting color profiles. Once you try other settings, you'll never go back to stock colors.

Kernels don't change this I'm afraid, and 3G will always use pretty much battery. Wifi on the other hand uses nearly nothing.
If you say you're not a heavy user then Franco's Kernel will be a good one for ya. As it contains hotplugging (meaning it will make the device slower if it's not used but fast when you want it to be)
Slower = more battery conservation.
Also let's you underclock your device. As for example you don't play games so you don't want it at 1512Mhz, you can run it at 1ghz and the time your screen is off lock it to 384Mhz (or a bit higher) which again makes your battery last longer.
It comes to a small downside, that kernel comes with its own app which costs a bit of money. But it's very much worth it as you can tweak it just as you want.

"unfortunatly" you need root before you can flash this. But there have been very useful links in previous posts, try those!
Then if you've done all that, look into Greenify. You'll notice a difference when using it, trust me

Hi easygoingx! i wouldnt recommend you flash franco for now. I have been using franco for 2 months , i purchased the app and everything but lately it's comsuming a lot of battery! it drained my battery a lot with last updates i was getting crazy!
if i were you i'll flash trinity!
i've turned on my phone 30 min ago and my battery is in 98%, with franco it would be by 92%
but if you wanna flash ,first root your phone and put a custom recovery (cwm or trwp) and download the zip to your nexus 4 and flash it from custom recovery.

That's definatly not the cause of Franco, but most propably some other apps rogueing. Try Greenify.

It's maybe the case with nightlies on particular devices.
I'm not the one to judge on that but on Milestones (Milestone 2 aka latest) there is nearly no battery consumption in idle and I've used Franco since r102 (newest is r136)
In the including pic I had flashed Milestone 2 from Franco, then afterwards changed some values in the app to my liking (aka max freq 1350, min freq 384 etc...) and then left it be for a couple hours and look at the result. Lost maybe 1% over nearly 4 hours. If I leave it on generally over night on wifi + data sync enabled, I lose about 2-3% (depending on the sync times ofc). I sleep approx 6h a night btw
Also feel free looking here and see all the positive comments of people and their battery! (also one of the most active and responsive forum topics around)
Therefore I highly recommend Franco!
Oh now I understand these terms. Thank you guys! I'm considering flashing my phone and change the color settings. I'm really annoyed by those washed out colors!
You know what really annoys me? That when I am on 3g and my screen is locked IT DRAINS my battery SO MUCH. Isn't there any ROM/Kernel that fixes that? I mean the S3 has this even on Stock and unrooted....
Hmm... Somehow my phone gets so warm lately.... I'm kinda worried.

They sure are.. but you can take a pick from like 30-35 presets (using Franco's preset myself). Trust me, the result is just... awesome! (if you prefer AMOLED (cause you refered to an S3, you can also change colors to that, it's in the spreadsheet here (check kernel column to see for your chosen kernel))

I doubt that there is a way around the battery drain with 2G/3G/3G+ but just having a different kernel will do miracles concerning battery life. Always feel free to ask this in the thread, maybe someone has a "solution" to your issue.
I don't know how often you're without wifi. But just make a tasker task like I have:
- "if wifi connected (=state)-> Data off"
- "if not wifi connected -> Data on"

Don't worry about it too much. The nexus 4 is known for having bad thermal handling inside the phone (read this) but it won't harm your phone in any way.
If however you are still worried just download the kernel and go to "Voltages", just press-25mV a couple times (I recommend 3 or 4x). This will reduce the heat generated from your device. (Yes your device can handle this, even more but I'm not responsible )
Another thing is what is getting hot inside your device, battery or CPU? Franco Kernel Updater (app) has Device Monitor which let's you check the CPU temps. If the CPU gets warm/hot too often or too fast, just reducing the max CPU frequency can help you out (1.5Ghz is "too" much anyway, you'll be fine with a couple steps less )
Hope this helped If you have more questions that I could answer, just quote me
Hello everybody!
I have a Note 3 N900, 5.0, L19, dr ketan rom. This problem existed even on stock, and on stock KitKat.
I have a problem with the battery percentage. The battery percentage goes down at a rate of, for example when browsing the web on Chrome, 2%-4% a minute!
Overall, the battery life is not good during to this problem, as you guys can imagine. Tried to do a battery cycle (emptying the battery and charging to full) with no success...
Bought 2 new (!) batteries, but still, with no luck.
What the he** can be the problem if not from the ROM itself?
Thank you!

Idk if I've been cursed at or something, every device of mine needs to go to repair at least once in its lifetime.

Can you give us more specific info about what's using your battery?
Install BetterBatteryStats and send some screenshots, this is an extreme problem I can tell. There must be something keeping your phone in full power all the time.
How hot is your device? Believe it or not, the battery gets affected extremely by heat since it Lithium-ion.
What apps do you have installed? Apps like Facebook and similar will cause consumption.
There's a lot of things that affect the battery.

Take a look at these.
I, personally, can't see anything special. Do you?
According do those screenshots you have excellent battery life! I don't even get half of that. The screen of your note 3 takes up lots of power. What I can suggest is to change you max Cpu frequency to 1490mhz and go for the intellidemand governor. The snapdragon 800 is powerful enough to run smoothly with that frequency. Try it and report back if it did any changes.

Oh right! I'm sorry, I missed that part. But just try to underclock your CPU a little bit and you should see a increase in battery life. Just try whatever frequency you want, the only thing that might happen is a slow device (you basically can't break the phone with underclocking, in fact, it's better for the CPU). Remember to change your governor to Intellidemand or Intellimand (can't remember the exact name).

I don't think that there are working custom kernel for the 5.0 N900... shame there's almost no more development for our phone..

i have this same **** problem
Ok, even with two new batteries and a few battery cycles with them, the percentage won't stabilize... Today the battery ran down to zero, and the phone continued to run (on 0%) for about 20 min..............
After replacing the battery, I was on 100%, dialed *#0228# and did the "RUN TEST" and the percentage went down to 23%. Dialed again and it went up to 82% and charged it. I can't seem to find a godda** solution for this problem!
What can I do to solve this?!!
up
I have a very odd problem that I can't solve nor diagnose, my device (N9005) keeps rebooting at no expected pattern if I changed CPU governor to anything but interactive or under-voltage.
The problem started about a year or so ago and since then I have tried lots of roms, kernels and batteries if they had something to do with it but I can't understand why the reboot happen.
I can record a cat log if it would show the problem and if someone can help identify the cause of it or if someone already familiar with this problem and solve it would be much better.
I would appreciate any suggestions in order to try and solve the issue.
What happens with stock rom ??

You mean AOSP or TW? since both can be considered stock in different ways xD
Anyway, the behavior is the same on either but the problem started while on Temasek's ROM last year which was and still my main rom.
Samsung stock TW .

Check your CPU binning (pvs) and read about it. You might find answers.

Thank you very much for the suggestion. However, after reading about it which is a very new concept for me so thank you again for that, I understood it affects overclocking speeds and tolerance but I still don't understand what could it mean to my case.
One thing I forgot to mention or implicitly mentioned is that, I used to use conservative or powersave governors and used to undervolt by 25mv till the problem occured.
Also, I think checking device's CPU binning method differs from a device to another (not sure if I'm right) but I tried a command found on OPO's site and it didn't show an actual output but it showed a 1 before the usual command line and I don't know if it means anything but thought of mentioning it anyway.

You can find your soc's pvs by navigating to /sys/devices/system/soc/soc0 then open the file "soc_pvs" with a text viewer.
There will be an integer (from 1 to 6).
1 means best support for undervolt/overclock. And 6 the worst one.
Your phone reboots when you just set different governor (no undervoltage applied) ? And which governor you set ?

Thank you very much for your reply.
I just checked and it is actually 1 .
The governor I was trying to set was Yankactive/ondemand.
There's a chance that the problem is actually fixed but I'm still not sure. However, if it's solved the reason would be ridiculous actually but compounded into 2 parts and I'm not sure if one of them it the main cause or both but they are the most recent changes which led to the current stability with no reboots since 2 hours now.
The first part is the SELinux status which was enforcing and had to change it to permissive for any heavy change otherwise it won't work and it kept changing after every reboot so what I did is forcing it to change to permissive on each boot. and it helped a lot but I'm not sure how it affected my situation.
The second part is that I was using PowerNap xposed module and there's a chance that it force stops the android system. I also have no idea how this contribute to solving my problem since the problem existed before even installing xposed.
Anyway, I'm still testing the device to see if it's actually solved.

Sorry i did a mistake.
The higher the PVS bin value the better. This means 1 is not good.
I have the value of 1 on my Note 3 and undervolt by 30 with zero problems. Also i change between interactive and performace govs a dozen times a day.

Undervolting aside, shouldn't I be able to change governors no matter the PVS bin value? since it matters the most while overclocking and I'm trying to do the opposite

I used to do too but no clue what happened on newer Android versions. BTW, which ROM and Kernel you are on?
Kernel: CivZ-KK_Xplorer-Rev1.9
Rom: Omega 4.4.2 v24
I am using both Synapse and Kernel Toolkit for CPU/GPU tweaking, as they wok well together (on the other hand Kernel Adiutor conflicts with Synapse).
In case you want to know, the battery goes down 1% every hour or so in idle and about 1% every 3 minutes of using the phone with screen on (browsing, gaming, etc).

Why do you say that? It's brand new (bought it original from Samsung, a month ago). One of the few new original batteries left in stock. manufactured at the end of 2014.
Only yesterday (@3%) i got 4 hours of gaming in Retroarch emulator (pretty intensive on the CPU), with a total of 4 h and 40 min SOT, with the Note charged to full 21 hours before that. Pretty decent performance imo.

O.O I'm terribly sorry I somehow misread your post.
I was confused when I read it since I was actually sticked to SlimKat before switching to nougat because of the battery.
BTW, what is your usual SOT without heavy usage?

Well, it depends on how bright the image is. That is if you watch some darker images or pages, it consumes less than white ones.
If i unplug it in the morning (i usually unplug it in the evening), the SOT is a sure 5 hours, with some 5 % left in the evening.

Aha, now with RR nougat and synergy the consumption is very close to yours.

Great Should be even better overall with that deep sleep option that nougat has.

When the device doze the battery percentage gets stuck for how long you may leave the device idle, it's pretty impressive
