I've been getting absolutely horrible battery life unfortunately.

15 hours, less than 50% battery and less than an hour of screen on time with autobrightness on.

ReVolt with franco's r71, LightFlow and Touch Control. They seriously shouldn't eat this much battery, do they?

I get horrible reception in my workplace, seriously considering just turning the radio off when I'm inside.

Worst wakelock is the msm_hisc_host for me. Seriously jealous of some of the reported runtimes some of you have been getting.

Sv: The great battery impression thread

Well if you play games like need for speed it wont last longer than a couple of hours. But if you use it to surf, make calls, texting etc it will last 4-6 hours depending on how many apps you have syncing and how often. And if you still only get like 2h just doing basic stuff then yes your mobile is a brick without a doubt and you should be getting a new one.

i've a strange behavior for battery, it seems to drop stepping by 3-4% instead of 1%....i.e i can use n4 and after 10 minutes i've the same level but after it drops 5%

any idea about this? should i calibrate battery, try to wipe or what? i'm on 4-5th charge circle as my n4 is new....

btw i can reach 3 hours screen on, it seems to be very good drain in standby, but when i'm playing with n4 battery falls down very quickly (aokp build-3 - faux kernel beta8)
[Nexus 4 General] davidsteele1975:
Yes; my Nexus 4 shows quite a high standby drain. It doesn't matter if I have data, WiFi or Bluetooth on or off, the drain is still the same.

Also, something to bear in mind is that the battery statistics are an estimate and the drain of a few percent in jumps could be solved by a complete drain and recharge calibration.
[Nexus 4 General] beren:
just to know.....it's the same if i recharge to 100% with telephone shutted off or on?

Guys how does this battery use look like? i feel Screen on time can increase .Moderate usage.

Any comments on this..

No Wifi, Mobile Data ON the whole time. location settings on the whole time. GPS off

Also does mobile data take more battery than Wifi?

i am on Stock ROM rooted and Franco's r71kernel
[Nexus 4 General] Mubz_C:
Yes mobile data takes more battery than WiFi, but since you have francos kernel not much more battery drainage
[Nexus 4 General] davwman:
Had the phone about 12 hours. Boot loader unlocked, rooted using xylon and harsh kernel. battery is excellent in my opinion. I'm on T-Mobile 80% and WiFi 20% of the time and have been using and abusing this thing with gaming, tune in radio, uploads on my 100gb of box space;), setting adjustments, fine tuning pie, undervolting, the list goes on. It will never get what my atrix HD with a maxx battery got, but I knew that. The development alone for this phone far exceeds the extra two hours of screen time my atrix HD got with zero development. This phone is fun, simply put. I will be buying the orb charger for home, and leaving my regular charger at work. People are entitled to opinions, but some negativity about this phone is just uncalled for. For the price this phone CAN NOT be beat. This is my third LG android device, all I can say is, I'm done with HTC, Samsung, and moto. Moto with the exception that they allow boot loader unlocking, but until then I'm staying here.

4.2.2 is out for some nexus devices ( not Nexus 4). It would be nice if the rev optimized the battery.
[Nexus 4 General] EvoXOhio:
I saw something the other day showing that the Nexus 7 now lists 10 hours of battery life instead of 8 as of the 4.2.2 update. So anything is possible.

If google could kill the wakelocks and also prevent the phone from running so hot, battery life would improve tremendously.
[Nexus 4 General] biggiestuff:
My nexus 7 sleeps better that's for sure. the battery line is flatter than before during inactive periods. still waiting for a few cycles to see if it's improved. 4.2.1 caused my average screen on time to drop about an hour which really sucked.

Nexus 4 on idle time

OK. first of good morning.

Today ill post images of my nexus 4 running stock everything. But instead of posting normal usage and stuff today i decided to post just idle time with a slight emailing.

Here are the conditions:

Wifi ON (data running in background)

Brightness auto

... and thats it.

Thing is i disconected cellphone early in the morning. i have wifi at home, then i drove to my job. Car has wifi as well. when arrival to job there is wifi as well. so technically wifi was avilable at all times. i answered 3 business emails that took aproximately 8 minutes and other 3 minutes of screenshots and just checking the phone.

So the results are 6 hr 52 min from 100% to 90%. almost 7 hours per 10% on stock everything. No Franco no nothing. Screen time during this lapse is 11 min. as a side note i would like to say that battery drain remains for me constant from 100-10%. from 10-0% battery holds even a little longer. But for numeric purposes i will consider that all this done in 10% i will tenfold and proyect some numbers:

100-0%: 68 hours (2.8 days)

Screen time: 1 hour 40 min.

Wifi whole time

This is what basically a person "could" get if they only use wifi all the time and use screen for 1 hr 40min MAX for light tasks as emails. Now i wont do the test myself because my job requires me to take pictures and use autocad on field, so for me that battery time is imposible, but these numbers might be of some use to somebody maybe.

Later on i will introduce 1 hour talk time and recalculate these number down to 90% battery. but for now i just recorded what happened naturaly this morning and proyected some theorical numbers.

Hope this is a guide or helps some one.

EDIT: This is on 4.2.1. Later on i will redo this on 4.2.2.(not here yet)
[Nexus 4 General] Flapo:
Nexus 4 on idle time.... Kinda

So i continued my day and my douche friends woke up at as always we started texting like crazy. more emails came in and i had to call a client for a couple of minutes.

So... down to 80%. Results:

9 hr 10min on 20% battery.

Aditionaly i leave for lunch to a local restaurant for about an hour and no more wifi, so thats 1 hour on hspa+, which as you can see jumps to 3g from now and then.

27 min of screen time.

12 min 43s of voice calls.

At this point i will consider this as "average usage" and i will now proyect battery five-fold to see theoretical numbers:

100-0% 45 hrs (1.9 days)

2 hrs 20 min of screen time

Wifi on with a bit of Data time

1 hour of voice calls

Lots of texting included with those 2 hours 20 of screen time

So its 1:12 in the afternoon. if i do go to do field work and take piictures then i will not be able to continue every 10%. otherwise i may post more as time passes by.

For now, this is my usage as of 20% in 9 hours of battery, everything stock. Hope this helps.

Hi,

I'm an Paranoid Android 3.00 with nova launcher and it is so freaking awesome! I love the possbility to customize every detail, this makes it really unique.

This is my realistic battery profile from 100% to 10% I mostly listened to music and browsed the web and mail... I think it is ok, I need to load it about every 24 Hours - when using it quite a bit.
[Nexus 4 General] Flapo:
Nexus 4 on idle time.... Kinda Less

Continuing my day, here the update:

down to 70%

11h 2min on battery

47 min on screen

wifi, LOTS of messaging and emails. google updates for 2 apps

so furthermore new proyections for full discharge. 70% would be 3.33-fold multiplier

100-0% 36.63 hours (1.53 days)

2 hours 35 min on screen time

Wifi on with a bit of Data time

1 hour of voice calls

Lots of texting included with those 2 hours 35 of screen time

As percentages drop by, the proyection start to converge on real life usage and real battery drain.

More updates to come.

Battery drain continues to be quite poor without WiFi. This is with a fair number of applications syncing in the background. Drain was about 5% an hour overnight with no active usage. The fourth image shows change in battery drain when changing from WiFi to HSPA with effectively no active usage or screen on time.

Edit: Save for the fourth image, these are from 4.2.2

hi there.

i think i got a problem with my battery endurance.

it's on screen time lasts ~2h 20 mins pretending on what i do. on the attached screenshots you can see. i used wifi and most of the time whatsapp.

brightness is set to automatic. gps, bluetooth and mobile data are turned off. sync is just enabled to sync chrome bookmarks.

i'm using aokp_mako_jb-mr1-build-1 and franco-kernel r50.

do you have any suggestions? i dont think this on screen time is ordinary.

if there is another thread where i should post this or if you need some more informations, please let me know!

sorry for my bad english, i did the best i could.

Stock before and after. Used to average around 4.5hrs with about 90% wifi. Installed 4.2.2 last night and now have 4hrs on screen time with 39% battery.

I would say it just got a lot better. Will try only 3G tomorrow as i would barely get above 3hrs on screen.

My battery impressions :

I'm coming from a Samsung Galaxy 3 so that's what I'm comparing my experience to. I have to say I am disappointed. I have no complains about anything else on this phone.its snappy, feels premium and I'm loving the pure stock Google experience even if there are some features I miss from touch wiz. However battery wise the galaxy I could go a full day with heavy use no problem. With the nexus I'm at 30% with only under 4 hours of use. Don't understand why.

Actually what I did notice is that on Samsung when I upgraded to jelly bean, my battery performance dropped so I settled for ICS and had no complaints there. On the nexus I turned off Google now thinking g that was the battery hogging culprit but it hasn't helped. This is running all stock apps.

I brought myself this phone to fully immerse myself with Google services. I want to have decent battery life with location settings turned on and latitude tracking everything I do. Maps and QuickOffice destroy my battery (4.2.2)

One can only hope that this is improved in the future :D
[Nexus 4 General] mysterioustko:
I can confirm that the battery is improved quite a bit. I have had several days where I've reached 17hrs or more with 2 hours of talk time and 1-2 hours of screen time. With streaming Pandora for about 6-8 hours, 2 hours of calls, and between 1-2 hours of screen time, I have easily reached 15-17 hours of use several times. Even on days where I used the phone heavily, I still easily would reach 12-15 hours without a problem. Compared to when I used 4.2.1, this is a marked improvement as I got nowhere near that sort of use.
[Nexus 4 General] theguitarman94:
Can you post your android version. I'm not trying to be a mod or anything but I'd think it would be really useful if people can just put 4.2.1 or 4.2.2 with their screenshots so we know the difference.

Doesn't seem any better to me. Lost about 10% idling for 8 hours over night while on the cell network with WiFi off. Msm_hsic wake lock is still killing the phone without WiFi on.

Hey guys, I'm on Android 4.2.2 right now and I feel like the battery lasts a bit longer than 4.2.1 just by 30mins~45mins. Has anyone else experienced this? Does 4.2.2 has wakelock patches? Or is it still unknown?

I got 3 and a half hrs screen time with 20 hrs standby time. Had WiFi and data on all day. But I work in a hospital and the cell reception here is bad and the phone constantly switches between no reception to 2g to hspa+.

My battery life has improved but from first impressions it's mainly standby consumption and WiFi. I'd say the battery with screen off on WiFi now lasts about 10x as long, it's barely draining at all now. Set it down last night, picked it up 6 hours later and it had used 3%, whereas on 4.2.1 it would have lost about 30%+!

Screen off on 3g is maybe lasting twice or 3 times as long; screen on while browsing on 3g or WiFi is marginally improved at 4-6 minutes per % respectively compared to 3-5 minutes - runs cooler though.

This is all going by battery widget reborn's discharge speed over the last 24 hours so very short term impressions.

[Nexus 4 General] qocarekeri:
The stock Quickoffice shouldn't drain your battery like that - it's just a document viewer. If you're using the paid version of QO, it may drain your battery a little because of it running in the background keeping files active. Just save and close any files you're working on then close Quickoffice to avoid this :).

I've been using 4.2.2 for about 3 weeks (Google sometimes sends out builds ahead of time to employees), and I've noticed a definite improvement in battery life. I got my Googler update while traveling, so I was constantly using Maps to find my way around NYC, GPS, Twitter, WiFi tethering, the NYC subway app, gmail, and calendar. I'd say my phone saw about 3-4 hours of total active use, and I had about 40% battery at the end of the day compared to about 20%.

A few notes on my use style: I'm from the old school of computers - back when you tried to have as few as possible apps/programs running in order to conserve system resources, so I use the task switcher to shut down apps pretty regularly, keep my screen pretty dim, and use black or gray backgrounds whenever possible.

The 3g radio on most phones is a large battery hog by nature, and the Nexus 4 is no different. This is even worse when you are moving which causes more signal searching.
[Nexus 4 General] qocarekeri:
I don't really think a dark background helps with it - but dimming the screen definitely does. It's just a lot easier to read and see things on a darker background with a dim screen, IMO. :) It may be because I'm used to an AMOLED screen - my last phone was a One S, and I've had a couple of other AMOLED's along the way.

For those talking about dark backgrounds saving battery, note that this is applicable for AMOLED screens, but not LCD screens. The N4 has an LCD screen, so there are no battery benefits to using dark backgrounds (unlike the Galaxy Nexus).

So I was fed up. So I did a restore of my original android 4.2 backup I made on day 1. Did the ota to 4.2.2 then left to charge all night. Been using for just over an hour and have around 75% left. So I'm hoping for around 4 hours screen on. If I get that then I'll be happy, before I went back to stock I usually lost around the same as I'm on now but in 30 mins, not over an hour like it is now!

Also, I'm on Full brightness, so once I've done this cycle I'll do it again with reduced brightness and see how that goes.

Using WiFi atm btw.
