Each time i get to 100% charge & then remove the charger..The battery gets discharged & drops down to 99% in just a few seconds of usage..Is it normal?I get 5Hrs SOT most of the time but it's just those first few minutes after 100% charge that i notice sudden drop
[Nexus 4 General] davidsteele1975:
Yeah, quite normal. Your battery meter is, after all, just an estimate... ;)
[Nexus 4 General] cobyman7035:
Ever since using wireless charger. I can't get 6hrs. SOT anymore

[Nexus 4 General] motoridersd:
Yeah, I can see my battery drain as I use my phone with 3G data, but others use as much data or more and still get good battery life.
[Nexus 4 General] blahblahyoutoo:
you're doing far too much and getting the same battery life and screen use as me.

all I have is AOKP on matr1x kernel, wifi only at home which is from 7pm-8am. hspa+ everywhere else.

also about 24 hours and 3 hours screen. lots of texting, google music/spotify/pandora. it's games that kills my battery. 1 game of scramble knocks 2-3% off the battery meter.
[Nexus 4 General] :
Here are my stats on normal use (whats app, e-mail etc. no game play)

stock rom and franco kernel m1. auto brightness and during the night (8-9hours) i'm always on airplane mode. i'm nearly always on wifi mode.

Thanks for this useful thread!! :good:
[Nexus 4 General] munsabin:
Yes. It's not a problem. Also apparently Nexus 4 doesn't have the best battery estimator thing so you might be using it for a while, the battery graph doesn't change and then all the sudden it drops like 3%.

You might want to try putting a custom kernel on it. I put matr1x 8.5. Been a day since I charged it. Got 5 hours of screen time, and I've been playing games, browsing, and watching movies on it. Pretty sick.

If you do - use trickster to limit charge to 95% - good for long term health of your battery.
[Nexus 4 General] motoridersd:
I have something on mine that is preventing deep sleep. It might be Mightytext, so I've uninstalled it. We'll see. This would explain the huge drain even on standby and when JD cuts off data it lets the phone sleep properly.

I mean, this is definitely not normal (and this is 100% wifi)

[Nexus 4 General] saniyal:
Can somebody give me some tips I would at least like for my phone to last a hour or 2 more. BTW I am using faux kernel with intellidemand and UV of -137.5 and I am on auto brightness. I have data on when indeed it so maybe a hour or two in and have talk time about an hour as you see here
[Nexus 4 General] Xers662:
7 hours SOT with GPS off, sync on and always on wifi
[Nexus 4 General] johnxarma:
what ROM?? :):)
[Nexus 4 General] mpttrung:
What kernel? I tried many kernels, but can only reach 4 hours with wifi :(
[Nexus 4 General] Xers662:
Running on stock ROM with Franco R121and 75mv UV.

What I tried was changed the sleep delay from 30 secs to 30 mins. By doing that my phone never went to sleep and I used it normally. Overall time decreased but screen on time increased.

On normal use I always have a huge time difference between awake time and screen on time, this causes a lot of battery drain and I'm not able to figure out what is causing it. Syncing was part a cause. Switching it off gave me 40-50 mins extra
[Nexus 4 General] motoridersd:
Can you post your battery graphs? I'm curious to see how much battery your streaming apps use
[Nexus 4 General] LTavaress:
This is the most I can get: 2 hours of talk time, 2h and 30 min of screen on, 1h playing Real Racing 3 and wifi on for 19h 36 min

[Nexus 4 General] motoridersd:
I have msm_hsic_host and PowerManagerService wakelocks as well, and I also use Spotify. What's your Media Server and Spotify time? Do you use A2DP streaming?
[Nexus 4 General] mil0X:
I might as well give you screen shots of it.

And no I don't use A2DP streaming.

Skickat från min Nexus 4 via Tapatalk 2
[Nexus 4 General] motoridersd:
I ask about A2DP because I stream Spotify through bluetooth in the car and was wondering if that's what caused the wakelocks. Since you have them too, it might just be a Spotify thing. You used Spotify for 1 hr 4 mins, and your PowerManagerService is 1 hr 26 min so I'd say Spotify causes that. The msim_hsic_host is at 2 hrs 6 mins, and I bet a good part of that is also your Spotify streaming.

I have no proof this is true, I'm just theorizing here. I'd love to see how those who stream music with Spotify do with wakelocks.
[Nexus 4 General] Johmama:
Ok, I needed a thread to ask this question in and this fits the bill perfectly.

Is it just me or does the battery take a little longer than the average battery to charge? I seriously don't know if I'm imagining it or not. It seems to me like it does, but I haven't seen anyone else mention it so maybe I'm just crazy. I dunno, it just seems like it needs to be on the charger longer than my old phone, an iPhone 4.

Don't get me wrong, this isn't a complaint or anything. The Nexus 4 is by far my best investment in a long time, I love the thing. I'm just asking if anyone else has noticed this.
[Nexus 4 General] motoridersd:
Nexus 4 has a 2,100 mah battery and the iPhone 4 has a 1420 mAh battery. So it takes longer to charge because you are charging a much larger battery. :)
[Nexus 4 General] shook187:
This phone is by far the fastest charging smartphone I've ever had. And trust me I had quite a few.
[Nexus 4 General] LTavaress:
I heard it has a Qualcomm technology that allows for faster charging, I think it's called Quick Charge 1.0
[Nexus 4 General] mil0X:
It would really be interesting. Are you streaming online or offline? I'm thinking that it might affect the wakelocks.
[Nexus 4 General] motoridersd:
I'm streaming to Bluetooth over HSPA+. My phone gets warm when I do. I don't think it used to do that before though, so I'm worried something has changed since being stock, but my battery life is MUCH better now than it was before flashing a custom ROM and kernel.
[Nexus 4 General] mil0X:
Funny enough I have the exact opposite feeling. When I was running stock, I feel I was getting about 4 hrs of SOT, with about 1-2 hrs of spotify, offline though.

I maybe have to go back to stock again, just to check if my wakelocks still are present.
[Nexus 4 General] motoridersd:
I've made some other changes to mine, like removing MightyText and undervolting, but in stock form I could never get more than 1.5 hours os SOT. My Spotify streaming is always consistent at around 1-1.5 hours a day on 3G, sometimes more on WiFi.

I still have some tweaking to do, but this is the best battery life I've ever had:

My BetterBatteryStats seems to have lost my wakelock info, but I had about 2 hours of msm_hsic_host wakelocks earlier today.

The Google Maps usage was due to leaving Google Maps open in the background without realizing it.
[Nexus 4 General] jboodram:
When ever you see media server draining your battery go into your apllication manager and look for media and end the process..idky but this prob exist witj my s3 aswell for some reason media keeps scanning for long periods sometimes..
[Nexus 4 General] motoridersd:
Managed to get pretty decent battery life (compared to what I usually get) without Juice Defender. I don't know why Google Maps is using up so much battery. I'll have to investigate:

I'm using PACMan, Franco r121. undervolted by 125 mv (I have a faster chip) and lux lite to keep the brightness at bay. I do bluetooth A2DP streaming from Spotify over 3G. I am also using radio 33 so I can scan fot LTE in San Diego.

My battery life of Nexus 4

Hi guys, here are my results of battery life (check screenies)

My configuration :

Xylon ROM (11 april build by banks)

Franco kernel

-100Undervolt

min cpu 384mhz

max cpu 1.3ghz

snapdragon battery guru app

checked wakelocks using the Wakelock detector app

greenify (google maps,facebook,truecaller were hibernated - but i still using facebook in between)

What i used on this day :

no charge in between, neither connected to pc

everything was off (data,sync,gps,rotation) except some minor usage of data and sync (sync was on for around 2 hours in total)

wifi was running all time, forgot to switch of even while sleeping :rolleyes: i should have done.

when wifi for off (for around an hour, then 2g data was on that time)

around an hour and half of total gaming (small games like Temple run 2, temple run OZ, rope escape, subway surf)

rest all time i did texting, heavy whatsapp usage, facebook usage,gmail.

From all this, i found that google maps are always stupidly running in background.. and i am not a heavy maps user, so ill disable them and enable them only when i need..

also facebook is battery hogger, i have hibernated it too..

so i guess I can get a better battery life from all this.

PS : any1 want to suggest me any more better ROM + Kernal combination?

Thanks guys ;)

Mine did pretty well! In fact I tried few configurations... The stats you'll see goes like this:

PAC 04/08 + Franco.Kernel r121

Max CPU: 1350

Min CPU: 384

Max CPU Off Screen: 702

UV -175mV (Very fast chip (4))

Max CPU: 1188

Min CPU: 384

Max CPU Off Screen: 594

UV -175mV

[Nexus 4 General] razball:
Hey guys I might have stumbled on to something since I got my rev 11 unit I've noticed better battery life.

But not compared to everyone else then today I charged it with the stock cable instead of my energizer wireless charger.

And the battery life has tripled or more normally I get 2 and a half hour sot with about 15-19 hours over the day.

This is a screen shot of just so far its ridiculous.
[Nexus 4 General] razball:
The majority of that time I was watching videos online
[Nexus 4 General] Beremus:
Same here, poor battery life when charging with wireless (Qi charging use a wakelock that doesn't go off after few hours after getting it off the charge.) I'm using a Energizer Qi charger. I don't know if this issues happen with the Google Qi Charger too? Maybe they will fix it, maybe not...
[Nexus 4 General] motoridersd:
I don't notice much difference between charging with my Google wireless charger vs a wired charger. My battery life is equally bad.

I have a question for those of you with good battery life. Do you use the Google Now services? I mean Google location enabled, tracking of traffic and travel times for appointments and all that? If I enable location, my google maps alarms shoot up and prevents my phone from going into deep sleep.
[Nexus 4 General] Beremus:
I turned off Google Now. It drained my battery a lot more than it should. But my location services, etc. are still on. I get ~24h with ~4h15 SOT. I did UV my phone a lot (thanks to my "very fast" chip) and my max freq is 1188.
[Nexus 4 General] motoridersd:
I have a faster chip and I'm still testing UV. I'm at -100 mv now. I haven't messed with max freq yet.
[Nexus 4 General] Beremus:
I UV by -175mV and it's stable. Still testing my battery life with the 1188 freq.
[Nexus 4 General] markeithst:
Gotta know how to tweak it ;)!!!
[Nexus 4 General] iShubham:
Hi, sorry for this stupid question, but why some people say that they have faster chip...is there any chip variant of nexus 4?

and how i know my nexus 4's chip is faster?

also if it is faster, then i can undervolt the phone more?

Thanks!
[Nexus 4 General] statecowboy:
See this thread. You can find out how your chip was classified.
[Nexus 4 General] iShubham:
Thanks for this :)

Mine says "Fast"

Fast can handle around how much UV?

I already have done -100UV, is it safe to do more -50?

Thanks!

I have a fast and am currently at -125... So far not had any issues... But the thread posted above has some good info on how much you can push it... Search that thread...

[Nexus 4 General] trillo69:
Just the amount of undervolting it can handle without crashing, and probably the same on overclocking. You won't notice better battery drain since undervolt has little effect on battery drain, it mostly reduces heat generation and throttling.

So I tried the technique of flashing a stock image again then putting on a custom ROM again... I'm getting about 1 hour more screen on time...! That technique strangely does work...

I had done it on my first N4 I had to RMA as well because I fried it in 5 mins while trying to root... Had to flash stock and used to get 5+ SOT and wondered why on the current phone can barely get to 4 hours... And well after the flash am at 4.5h with another 18% to go :)

I strongly suggest everyone give it a try...

Sent from my Nexus⁴
[Nexus 4 General] iShubham:
Hey, can you show any tutorial for how to do this, because I dont get it, to flash stock and then again putting a ROM :confused:

means after stock, again recovery and root it? and how is that supposed to increase :confused: i dont get it,sorry
[Nexus 4 General] DrunkFuX666:
Just use the Nexus 4 Toolkit to flash a stock image again... After that then use the same thing to root and put on custom recovery... Flash your ROM... And good to go... Just make sure you backup your SD card before doing so because flashing stock image wipes the entire device... The bootloader however will remain Unlocked...

For more info you can check out this thread...

[Nexus 4 General] emailrob:
I'd pretty much turned off all notifications in a desperate attempt to improve battery life. I spend around 12 hours on cellular and 12 hours on wifi, with 7 of them in deep sleep during the night. Also been using the qualcomm app but it didn't make much difference. By 6pm i was left with around 30% and about 1-1.5h of screen time.

I then installed DS Battery Saver. I have it on balance mode, meaning it deepsleeps while screen is off, and wakes an hour for 1 minute to get notifications. given all notifications were off for me, I really don't even need it to do that.

I''ve set a custom reference so will update this post later. But I'm now seeing a dramatic difference. Its lunchtime and I would normally be on around 60%, and I'm on 87%. Yesterday was the same. i plugged it in with about 50% left last night - which has been unheard of.

Despite looking at wakelocks for 2 months, I wasn't able to trouble shoot issues. I thought it was maybe a weak cellphone signal, but have full bars most of the day. Looks like it really was a data issue.

So at the moment, despite my better judgement, this seems to be a decent (hopefully interim) solution.

Texts and calls come in as normal.

The downsides: when I wake my phone, I have to wait 2-3 seconds before data is ready to check emails. Not a big deal. I've not tried GPS and streaming apps, but I think these can be whitelisted not to sleep when the screen is off.
[Nexus 4 General] motoridersd:
Sounds like my situation, but I do have tons of notifications coming in all the time. I'd guess using a similar solution to force deep sleep would yield much better battery life, but even then, I doubt I would get more than 2 hours of SOT since the drain would be high while the screen is on. It'd be interesting to see how your SOT does with this interim solution.
[Nexus 4 General] Ok_Kaleidoscope5109:
Everyone loves objective battery tests.

I wasn't happy with my past test because my gf's place's internet is sometimes flaky, and that I used my daily ROM.

In my second test I did the test at my home which I feel has far better internet and is more consistent (subjective observation). I also used a special Nandroid which runs a bare bones copy of CM 10.1 M2. This helps eliminate the ARP fix that people claim kills battery because M2 was built on March 4th???

I ran both tests at night with Battery Test Utility. Somehow I think the brightness sensor is more messed up in M2, but it read 87/255 for the battery test utility app, so expect run times to be worse than my first test. The important part is we can compare the results. I ran CM 10.1 first, and then Franco (last night). I used the browser test which refreshes 10 URLs via wifi at fixed intervals. BTW I used r122 for this test. My last test used r121.

Here are my results:

CM 10.1: 3:14:11

Franco: 3:11:57

If you gave me a Nexus 4 to test with, I'll run these 10 times and do a t-test, but I'm not wasting recharge cycles on my own phone. With that said, I wouldn't say that omg Franco is worse, or CM10.1 is wayy better. I think we need more data. But I think at the end of the day it's not the easiest to spot the differences between the two kernels. Maybe we need more tests to do that, but this is a basic SOT while the CPU is working in the background.

Now flame away.

DISCLAIMER: I love Franco kernel, I do. I'm not here with a goal of proving battery life of one kernel to be better. I'm simply trying to find if there's difference and if so what that difference is.
[Nexus 4 General] iShubham:
Okay, so I flashed back to stock and then rerooted with new recovery install and then installing Xylon ROM and Franco R122

Here are my stats with some gameplay and most of time whatsapp , chrome , FB

Check attachments! I didnt find much improvements though, ill test again today!
[Nexus 4 General] DrunkFuX666:
Its quite apparent from your graph that you restarted somewhere towards the end... A sudden dip in the graph of about 10-15% which is unaccounted for... That much battery will at least give another 30 mins SOT... Which would put you in the 5+ hrs slot which in my opinion is really good...

Also your signals arnt that good clearly... Which takes a heavy toll on battery... Yet your getting pretty good life... With GPS use and all still churning out that much I think is quite acceptable...

Rom: slimbean build 3, Kernel : faux mainline 4.2.2.

UC to 1350, UV to -150 globally and ECO mood is on all the time, i believe ECO is the main reason to get this result. UV -150, its truly cooling my N4, i cant feel any heat at all unless when playing games. I/O : sio, governor: ondemand. 3g, mobile data off, using WIFI all the day, location off,

Daily usage : facebook, instagram, whatsapp, flipboard, news, sms, skype, chrome and most wanted (when i play this game i still use that setting i mentioned above and no lagging at all !!! ) give it a try if u want a cooler and long battery life N4. :D:D:D

man i dont know what I am doing wrong.

im on stock 4.2.2 and franco kernel undervolted CPU -100 across the board.

downloaded GREENIFY and HIBERNATED ALL apps except better battery stats AND CPU Spy

disabled GOOGLE SYNC

disabled GOOGLE NOW

WIFI set to off on screen off

using WIFI ALL DAY at work

and still i get horrible battery life.

im at 67% now with only 4 hours and 18 min so far on battery and 1 hour of on screen time.

i dont get it. i have disabled EVERYTHING and still my battery is the same as it is with everything enabled.

any other options or advice guys?
[Nexus 4 General] DrunkFuX666:
Uninstall fb... And check BBS as to what is causing wake locks if any... I would suggest you flash stock 4.2.2 again from scratch and see the results...

Sent from my Nexus⁴
[Nexus 4 General] nextelbuddy:
BBS never shows any odd wakelocks or kernel wakelocks and under the OTHER tab it never shows anything odd eating up battery and shows DEEP SLEEP as you would expect during the times its deep sleeping.

Facebook is hibernated using Greenify so in theory it should not be using any battery unless I use it which isn't much however I can try what yuo have suggested.

it just sucks that I literally have hibernated everything and disabled ALL SYNCING and now the phone is basically dumbed down and doesn't retrieve notifications and I have to retrieve manually and still i get teh same battery life yet others on here get 5 hours screen on time and 1 day of battery..

ugh so frustrating...

makes me think how are they even using their phones..

whats the point of having as smart phone if you have to disable everything that makes it smart just to get battery out of it.

Don't get ahead of yourself just yet... Flash the stock ROM again and see if that helps... A full format... I havnt frozen anything and touching 5hrs SOT so its clearly an isolated event with you... Maybe some virus??
