I just came from an S3 and had read so many horror stories about the battery life of the Nexus 4. It arrived last night and I didn't bother checking out the stock rom as I immediately flashed AOKP with franco kernal and let me say...battery life has been great thus far. No question it is an improvement over my S3.
So for those who are having major battery issues, I suggest trying a custom rom/kernal.
Thanks to all the developers...I was nervous about making the switch to Nexus, but am very happy so far.
Well yeah....did you try everything on stock and see the battery life from there?
I haven't either. LOL.

How could you possibly know whether the battery life is good or not if you've only had the device for less than 24 hours.
The battery life on one of my Nexus 4s was great for about a week, then it slowly turned to crap.
The battery life on my other is still holding strong...
With my experience, battery life generally gets better as you go through a few cycles. I charged to 100% and with an hour of screen time and 5 hours up time today, I am only at 85%...and I've been on HSPA practically the entire time. With my S3, I would drain 5-8% an hour on HSPA with zero on screen time.
I'm using AOKP (4.1.2) and I really love the rom itself, but I got the feeling that my battery is drained more when screen is on than usual.
With screen off I get good battery life - like 0.5 - 1% battery loss per hour with the standard samsung battery.
But when I surf over wifi for like 15 minutes the battery is drained like 10%. (I always use lowest brightness setting)
I know that the screen really eats through the battery, but this still seems rather high, doesn't it?

Welcome to Jelly Bean. :highfive:
That could be it - so far all jellybean roms I tested seemed to drain more power with screen on than ics or gb ever did.
And my problem is not related to no deep sleep or something keeping cpu alive - when screen is off everything feels normal.
I have reverted to rocket rom v12 cause that... JB is nice but this battery leak is not acceptable for me. Rr v12 is best solution definitelly.

What I found out so far: auto-rotate on is a battery drainer - with it on system_server constantly stays at like 5-10% cpu usage, android.system.ui also uses more CPU % with auto-rotate on, CONSTANTLY.
I've read this is due to a too short polling interval for the location sensors, if someone knows how to change that please let me know, but I'm also trying myself.
Use BetterBatteryStats, my friend, to check if there's a wakelock with some app.
battery drain
i am watching this thread, because i also encountered battery drain on JB. thought battery is gone. hence bought a new one. slightly better but still drains a lot. i think the battery drain is because of smart stay. smart stay uses front camera to decide whether you are looking at screen. so when screen is on, front camera is also on and hence the double drain. at least for last four hours, battery drain is in check, after i turned off smart stay. hope this is right and help all of you.
I have the same issue.. Infact I believe this damaged my Battery.. it was working fine until I was on Stock ICS. After I flashed JB LSZ, I noticed heavy battery drain as well as wierd battery status indications..
Just today I noticed that the battery is slightly bulged..
it might just be the wrong time, or something with the ROM..
my phone is just 15 months old now.
Well to be honest my battery life is "ok" - I do get like 1-2 days depending on usage. As I already said, when the phone is in standby mode it drains very few power like it should. (I do have flight mode on almost all the time too, because I don't use it as a phone, just for data when I need it)
But I got this feeling that the battery drains alot faster than I was used to on screen on time since I'm on jellybean. The thing is, that I've checked almost anything, with BetterBatterystats, BatteryMonitor Widget and Powertutor.
The drainers when screen is on are #1 the Screen and #2 Android-System using the CPU. I've already deactivated auto-rotate and the media-scanner, this helped a bit. The only process that's really showing up in System Load is "android.system.ui" at like 2-5% CPU.
Is this jellybean-wide or could this be due to the additional AOKP tweaks?
How can I break it further down to find what really causes the load? (beside Screen taking more energy on JB which would make no sense from a physical viewpoint, the cpu-usage of android.system.ui can only be the other cause of the battery drain right?)
Hello.
I noticed that on CM is battery drain faster than on stock LG rom. How is this possible if lg rom is bloated?
Has someone bettery battery life with aosp rom, or is LG always better?

It all comes down the the kernel for the most part, in this case, I have seen exceptional battery life with AICP - http://forum.xda-developers.com/showthread.php?t=2494700 -
It's been stellar, and has an unbelievable number of options. It has rebooted on me in a week all of twice, which is way acceptable in my book compared to the bloat and stuff that comes on the LG rom. I love the rom, tons of themes out there on the playstore for 10.2, etc.
I was wondering the same thing, if the battery was going to be better or worse on AOSP.
I've been debating what direction I was going to go with software on my phone AOSP or custom stock
So i tried CM M1 snapshot. Usage was same as with debloated stock LG rom. Sync on, wifi or internet on, some low brightness and some high brightness.
I think that even phone was used more with LG rom, for same period of time LG rom was at 78-80% and CM rom was at 69 %.
As you can see from screenshots, no wakelock on CM.
Second screen is display.
In my experience, lg rom giving me better battery life than cm.
I get 24 hours battery life with 5 hours SOT with LG rom, with cm I only get around 4 SOT

It s quite big difference. Hope that future roms and kernels will improve battery compare to stock.

Taking your battery to 69% after 18 hours with an hour screen on time is not an indication of anything other than great battery life for the first 18 HOURS!!
Then you DON'T post screen shots of the LG ROM and just say "I think" it was 10% higher and are upset?
At the rate you're going you'll be at 3 days with three hours screen on [email protected][email protected] - Now THAT was a scientific calculation!!
battery
For awhile i thought CM was better, but running the 11/7 version, it seems to be draining faster than stock
I haven't been particularly happy with my battery drain running AOSP (Cyanogen mod nightly at the moment) which is a pity because other than that it runs great.
What I've been doing is charging my phone up to 100% before going to bed then leaving it idle (connected to wifi) while monitoring it with BBS.
What I've found is it's draining at around 3-6%/hour. The strange thing is BBS shows that my phone is going into deep sleep mode so why the battery drain, possibly powermanagerservice wakelocks?
...
I made second test. Tried to use CM and stock ROM in same way (browsing, fb, some videos, calls, mails) plus I greeniefied some apps and some system apps and with same screen time I have result 84% stock rom for 1:20 screen time and 70% for same screen time in CM M1 snapshot.
On both screen was mostly at 0%, sometimes about 30-40% .
Honestly, can´t find any explanation why CM drains more battery, every post or article just said that it was wakelock or that CM just drains more battery.

Wow. What´s your magic.
Also, how's performance for you?
I'm running a build of Exodus 5.1 with the boeffla kernel, and I'm getting around 3 hours SOT from 100% to 0% battery. That said, I have it set up in a way where I have zero lag (not using performance governor) and I'm getting 76206 on Antutu. with. I've also got Greenify and Amplify.
Just as a side note, how is your charging? I'm getting around 200mAh in (from my best cable and charger) boosted to around 650mAh using boeffla settings. Isn't that a bit low?
Atleast for me and my OPO, only the original charger and cable gets reconized as AC Charger, everything else i plug in as USB Charge, thats why the chip is force values around 200-650mA.
Boeffla Kernel can show u that, if the app says "Ac Charger" + a mAh value then u'r good, if it's not and just shows only a mAh value instead, the Cabel and Chager are reconzied as USB Charger therefore the IC Power Chip limits the throughput.
Sultanxda's 5.1.1 caf rom. Can easily bit 6-7 hours sot. Stock kernal
Before switching roms you should try wakelock detector and/or better battery stats to see if something is keeping your phone awake and killing your battery.
I don't worry too much about benchmark scores, focus on how your rom runs for everyday usage. Performance is just fine for me, but I don't play any heavy games on my phone though

Stock ROM and Boeffla Kernel, 6 hours of SOT with a battery friendly configuration (light undervolt, small underclock and balanced governor), but performances are still great with no lags. However with the stock kernel I never went below 5 hours, which is already a great result
used to have 8h SoT on KitKat. any lollipop / MM rom gives me max. 4h.
Darkobas best battery for me. Around 6 hrs. Then Herna's Omni and RaCyan: more than 5hrs.

slimsaber 0r Omni 6.0.x and sultan CM 13 06/12. CM 07/12build all giving 5+ hrs SOT for me.
I got about 5.5hrs on data (mostly LTE) yesterday across about 14-15hrs usage.
Sultanxda CM13 rom. Everything stock. No greenify and amplify and stuff. Turn of keep awake and wake up for google play services.
recently switched back to kitkat after realizind nobody was gonna fix the sitty battery life on 5.x and upwards. Not regretting my decesion. Bear in mind this is a one and a half year old phone that has seen daily usage, almost half of it was on 5.x, waiting for a battery drain fix. When it didn't come, I came back to 4.4.4 and I'm happy to say my battery is still healthy (was a bit worried all those months running a battery draining rom would have strained my battery). Cant tell you anything about charging since im using stock kernel on official CM11S with a stock charger, other than the fact that it charges really fast. Performance is so good that i decided to try and undervold (to 1950~) and im seeing no noticeable difference. Device is nice and snappy. I'd wholeheartedly suggest a switch to kitkat for the time being for anyone that wants to max out battery usage.
Note: These screenshots were taken after only the 2nd battery charge cycle so the battery still isnt calibrated all the way. After a few more charge cycles, i could probably get back to what i was used to on kitkat in terms of battery life: namely 8h screen time.
Darkobas ROM lightning kernel stylo king smartmax profile 1st charge cycle
My phone running on stock COS12.1 and can get around 7-8 hours of SOT with WiFi in 1 day usage. On 2 days usage SOT 5 to 6 hours. But on Mobile Data I getting a 4 to 5 hours of SOT. For charging I using Apple's wall brick from old Ipad and original OPO cable - 0 - 100% in less then 2 hours.
Sultan cm13 nov build. Getting constantly over 5hr sot with LTE. Standby time 12-16hrs.
Disable the wakeup for google play services.
I'm on sultan's 01/01 cm13 build. Currently have 1:43 sot and am at 78%. Was at 92% after upgrading. So that's 7.357 minutes per 1% battery, or 12.26 hours SOT. Wakelocks are not an issue here because this is continuous use on about 30% brightness, wifi and lte on, sync on, Web browsing and YouTube only (no gaming). Completely stock build with no power saving bs. Sultan for president!
TLDR; depending on your useage, 12 hours SOT on cm13 is possible.
4.4 with cm11s
I've never had more than 2 hours SOT with any rom (stock, sultan's caf, exodus, and others), do I have a battery problem?
5,5-6h SoT with Fusionjack's SlimSaber 6.01 which is based on OmniROM Sources. I'm using this ROM without any modifications, like custom kernel or xposed, neither i'm using things like greenify or similar. I've just tuned the power profiles to save battery while screen is off and limited max cpu frequency to 1958MHz to prevent heating. I'm using Facebook+Messenger and WhatsApp, which are by far the biggest battery hoggers and running Google Now with on Tap with GPS at hight accuracy the whole day. So the reached SoT is absolutely nice. Calculatory that would mean, without Facebook, WhatsApp and deactivated GoogleNow and GPS i could easily reach 8h SoT, but i prefer the comfort over the battery life, coz that's why i'm having such a smartphone.
Sultanxda CM12.1 rom w/ the kernel it comes with. With LTE/WiFi mixed use all day, getting 5-ish SOT and 24 hours battery life total. Installed Greenify but have it limited to hibernating 3 apps only. Likely going to fool around with profiles to see if I can squeeze an extra 3-4 hours out of it.

Hi, I'm running the same setup as you, I was just wondering about the level of screen brightness you are using? Is your phone running on full brigthness, 10%, 50%, 70%? And are you using apps like greenify, nap or anything similar?
I'm getting good battery life with your setup but not as good as you. My screen brightness is always set to full and I'm sure that could drain my battery faster. So I'm just curious to about what level of screen brightness everyone is using approximately to get these kind of great screen on times. I'm just super impressed and hats of to you and everyone who achieves this lenght of usage!!

I got best battery with Darkobas, but my best is around 6. It depends on alot of things: your battery, your signal, your usages... I think my battery is old and the signal here is weak. So you can only compare to your battery life with other roms, other kernels...

I definitely understand that and the factors there is. But I was just wondering if those who are receiving 6+ SOT have their screen brightness turned down or if their screen brightness is fully turned up.
I'm a little confused and frustrated by this, and I'm not sure what is the correct solution.
I used to be on Cloudy G2, then I switched over to somboons stock ROM with Dorimanx. That was pretty good, especially with the kernel profiles from Dorimanx. But sometimes, lag just killed me. I got to the point where it took me 5 minutes to even edit a single snapchat. Battery life was meh: approximately 1.5 to 2 hours of screen-on-time (SOT). I put in a new battery, and it was similar.
So I switched to Dirty Unicorns 5.1.1. Performance was really good, loved the customizations and features. Idle battery drain was pretty good too (usually less than 5% loss over night), but overall SOT was same as before. Active battery drain was pretty bad. But I couldn't get weather animations to work on the lock screen, and there was no SmartStay.
Now I'm on NDM 5.5, which is a really nice looking ROM, but performance is a bit lacking. Idle battery drain was excellent (close to Dirty Unicorns), but active battery drain was horrendous. I flashed Xceed build 16, and it was the same. Xceed build 14 is a little better, but active is still ridiculous. To give a perspective: I was on reddit, on auto brightness for about 10 minutes.... and I lost 12%. Yesterday, when I unplugged, made two 10 second calls, and then let the phone sit while I ate dinner... I lost 18% in 20 minutes.
I'm at a loss at this point. I've read some posts that said to give it a few days before judging battery life, so I'll wait a bit, but I'd like to hear your thoughts. Should I try another battery switch? Is there a ROM/kernel combination that might give me better battery life? If it helps, the most common things I use my phone for are chatting, reddit, and Puzzle and Dragons.

Edit: I switched from Xceed to Dorimanx, and for whatever reason, battery drain is worse now. Here are some screenshots. This is right when I woke up, so all that battery drain was happening in my sleep. Any clues what I can do to fix? I'll probably flash another ROM later, but I'd like to know if there is something wrong with my phone or battery or something hardware related, before I go for software changes.
