R: The great battery impression thread

Edit: got it
[Nexus 4 General] kara mustafa:
Has anyone problems with percentage battery indicator? I mean, the battery stay on 15 % for long time and then drain quick to 7 %, stay, and drain to 1 % and and stay there. Is phone broken or what ? Reboot can fix the percentage indicator
[Nexus 4 General] Mr.Mischief:
I've had it stay at, say 77% for a while and then suddenly drop to 74%. This mainly happens on 3G.
[Nexus 4 General] UK-Sense:
Just running stock everything and I think the battery life on the Nexus is great. Way better than my Sensation.

I have all the Google stuff running, BT & WiFi always on and my screen is always full on, getting more than a day of usage and that is email, texts, calls and reading forums as well as a bit of internet. I'm really loving this and its still on stock :)
[Nexus 4 General] shadehh:
Same experience here coming from a one x. This device IMO has one of the greatest battery of any device i've ever used before in all honesty. I only experienced version 4.2.1 for a day so i can't tell how battery really was back then, i'm on 4.2.2. after at least 2 weeks, my battery has improved day after day. I can get between 4:30 hour minutes screen on to 5 hours with wifi only - texting,whatsapp,browser,xda app,gmail.

With 3g i can get from 3 hour 30 to 4 hour 30 screen on time, it really depends on the signal in the long run. In fact, i've not even come to a point yet where i've completely drained my battery. The lowest i've ever gone was 10% and that left me at around 3:30h screen on time. Easily get 4hours.

What can i say? I'm happy! Great device.

Added pictures below, mixture between 3g and wifi - not on constantly, only when needed.
[Nexus 4 General] catlog:
I have the same problem. I once was walking back home, browsing the internet at 30% charge. Ten minutes later, a message appeared showing my battery was low, at 4%. Rebooting the phone brought it back up to 25%. I'm not sure why this happens.

---------- Post added at 02:46 AM ---------- Previous post was at 02:42 AM ----------

I always have at least 4 bars of signal where I am and I find with non stop usage of the Nexus only browsing via Chrome, using Tapatalk and checking Facebook, the battery only manages just under 2 hours. Nothing suspicious in Battery settings neither.
[Nexus 4 General] C0dy:
I've heard of some people claiming that the battery life of the Nexus 4 is worse than the Galaxy Nexus with normal usage, which I seriously doubt. Is this true? I ask because I may be getting a Nexus 4 soon.
[Nexus 4 General] Silencer96:
Not at all. As long as you stay on stock 4.2.2 or at the very least flash Franco's kernel, you should be good to go. :)

EDIT: But if I were you, I'd stick with the Galaxy Nexus for now and wait for the Nexus 5 to come out. This phone is great and all, but it's not that big of a jump from the Galaxy Nexus.
[Nexus 4 General] shadehh:
IMO the nexus 5 will probably be even less of a jump than from galaxy nexus to nexus 4. Why?

One of the fastest quad cores? Check.

2gb ram? Check.

Latest android OS? Check.

At this point the only thing that can really change is maybe improved battery life on the n5 and maybe a faster processor(which shouldn't change much in day to day apps and phone usage).

Maybe 1080p resolution if google wants to follow the trend.

Edit: I have been hearing that 1080p is mainly a marketing hype. While it may improve the visuals a TINY bit it doesnt seem like a huge jump

http://arstechnica.com/gadgets/2012/10/1080p-on-a-smartphone-screencan-it-possibly-matter/

If the difference is really not that obvious, I would rather keep this resolution and focus on battery life next generation. I have the feeling battery life wont change much. Still excited to hear about samsungs octa phone. Hopefully a start in the battery efficient direction
[Nexus 4 General] Vahndroid84:
hi guys...is there a relations between the power manager service wakelock on BBS and the battery stats Android Operative System? I'm trying to dig why i have worst stats in my office and i see the the android operative system boosts to more than 1hrs when the phone is in standby (screen off) when i'm in office. I have gmail, contacts, chrome and position synced on (GPS off). I have tryed to disable the position sync but the android OS stats has grown by 5 minutes in 10 mins of standby.

I know that the Android OS stat is related to the apps...but i have only 1 dash clock widget running and 1 weather widget (updating every 3 hours). I have "greenified" facebook, Twitter and tapatalk (to test).

this is a screenshot of the stat
[Nexus 4 General] undercover:
I really can't complain. About 17h off charger yesterday, 4.5h screen on, some of it (1h) navigation, and i put it on charge at 11% left.

RBJ/Harsh combo.
[Nexus 4 General] namttn:
What best kernel can i use with PA ROM? Now i considering franco or motley ? Somebody give me an advice ?

?
[Nexus 4 General] Vahndroid84:
Im using harsh kernel...and it seems good. I think i will try franco too...but you have to test them to find your way ;)
[Nexus 4 General] undercover:
Today's stats so far. SOT from Tapatalk, currents and a bit of browsing, nothing CPU intensive.
[Nexus 4 General] MrPhilo:
I can get 5 hour and 30 minutes on screen time on wifi, around 3 hour on 3G/HSPA etc.
[Nexus 4 General] thatguy188:
Idk how the hell tall do it but this is me today running latest trinity and cm10.1.

Btw the gap in battery was me flashing ;o but this still seems "normal" for me (or crappy compared to yall)
[Nexus 4 General] shadehh:
@thatguy188, hmm odd indeed. Isn't cm though known for great experience but in return less juice?

Anyways, without flashing rom you would have easily broken the 3 hour 30 mark I believe. I think when it comes to phones the signal plays a much more significant role than we think.

Anyways here my stats so far, I restricted myself to 3g only and it looks like I will be hitting 4 hour to 4 hour 30 mark. Quite happy. Almost as good as with WiFi. Impressed I am :).
[Nexus 4 General] mpttrung:
What kernel u using? Also ur brightness setting?
[Nexus 4 General] undercover:

[Nexus 4 General] C0dy:
Thanks for the info.

I would stick my Galaxy Nexus, but my USB port is starting to go bad, I have to wiggle every cable I own around until it starts charging. If that didn't happen, I would stick with the Galaxy Nexus.

[Nexus 4 General] Silencer96:
FaceBook is draining your battery like a b. Try uninstalling it or at the very least disabling all the notifications.
[Nexus 4 General] tell4ever:
Well this is honestly the best phone I have owned from the battery life prospective

These are two different readings,

I get around 4-4:30 hours screen on every day

When phone is up for 15-18 hours

I don't do gaming, I use Facebook twitter taptalk aloooot and each day I listen to 2 hours of podcast and some YouTube and messing with play store

Satisfied with pa and harsh kernel...but i will try franco too

[Nexus 4 General] Vahndroid84:
Mine usage is medium-light...it's just a few whatsapp and a few message with facebook messanger...a couple of calls for a total of 10 minutes. 2 videos from youtube and light browsing with tapatalk, chrome and flipboard

Does avast antivirus takes a lot of battery usage when running??
[Nexus 4 General] Ieatnoobs:
I would say yes since it keep running in the background. I don't use a antivirus on my Nexus and quite honestly I don't think you need one if you know your browsing habits and don't just click on any email/link/attachment/whatever without inspecting its source.

My typical day...
[Nexus 4 General] DarkShot666:
My area is bad for getting any reasonable battery life like some of you folks.

Bell doesn't support 2G any more, and my work place gets absolutely horrible reception unless you're in very specific areas. Couple that with the infamous msm hsic host wakelock and other radio-related locks, I don't think I'll ever get more than 2.5-3 hours screen time on 3G.

woot.
[Nexus 4 General] extradom:
battery is really bad

I need recharge everyday......
[Nexus 4 General] sub1287:
I only need to on my days off, during the work week I have no trouble making through the day and get a solid 4+ hrs screen on time. No WiFi available to me or it would be much more.
[Nexus 4 General] Ieatnoobs:
Not too bad. First time ever breaking the 4hr mark for me. Francos kernel and lowering frequencies to 1.18ghz max and 384mhz minimum.

I'm on the latest Paranoid Android, Faux 009 kernel turbo boosted to 1.9GHz, interactive gov with no OC/UV. I have yet to try intellidemand (is it really better?) and I keep Google Now on 3G all day with no WiFi. I get back home from my 11-hour day of work & errands with a good 45% battery left so I've got no complaints whatsoever.

I would say I give the phone medium to heavy use on a typical day--I just got this baby the other day and I have to say I'm impressed.

Wifi/3G always always on

Full sync.
[Nexus 4 General] gee2012:
It all depends of how you use your phone, i don`t think there is a general best setup that applies for everybody. It is best to try a few kernel`s and rom`s and keep the ones you like best.
[Nexus 4 General] rahulmaheswari:
Screenshot attached for the other tweaks to the governor. All these have no or negligible impact on performance for regular use. Cannot comment on intensive gaming though.

I am quite impressed lately with my battery. I never had this with any other android phone of similar screen size. This is normal use for me. Often checking gtalk and messages. But my habits kept the screen of between messages so the screen on time is a little lower that what I would refer to as conscious usage. I am not restricting my usage in any way.

Guys ive wiped my nexus but im still having the android OS keeping the phone active when it s in standy and connected to a wifi network (in 3g it doesnt happen). My android os is the second stat that drains the battery and in 10hrs it has reached 1hr of keeping active the phone. Which widget you use? I have only a beautiful widget for the weather...and dash clock in the lockscreen. Ive freezed facebook and chrome with greenify. Ive very few app installed...twitter...flipboard...linkedin and titanium. Ive sync active with gmail...calendar...chrome and contacts. Position is synced but gps is off

Something still not right with Android to be honest. I was getting 2 days battery life with 5hrs approx screen time, pretty impressive. (totally stock).

Guys i need a hand cause im going mad. I have checked my girlfriend nexus 4 and she never have the "keep active" status of the android OS stat in battery draining (she is in stock). Yesterday my phone reached 2hrs of keep active in android OS stat...Then i just factory wiped my phone...flashed pa and harsh kernel. Ive installed nothing! Just chrome and there it returned the keep active its still here and i dont know how to trash it.

If a factory reset what could work? I never had this android Os before...it s a matter of the last 2 weeks...

tegra 4

In the Exynos 5 Octa, the a7 cores perform at upto 1.6ghz... but the a15 are limited to 1.2ghz.. which shows that samsung was really worried about the load consumption of the a15 cores... on full load..

tegra 4 early benchmarks (antutu 36k ) was probably running the cortex a15 cores.. all four.. at 1.9ghz... and since it was a tablet.. connected to usb .. they were not worried about the power problem..

I read an expert analysis on the tegra 4.. there they said that all 4 cores.. at 1.9ghz.. full load could consume almost 10W of power..

now calculate:

nexus 4 : 3.8 volt battery with 2.1 Ah (2100mAh). Therefore total capacity is 7.98 = 8Wh.. so this means it can provide 8A for 1 hour or 1 amp continuously for 8 hours...

The review on notebook check pegged the max consumption of the nexus 4 at 6.5W

http://www.notebookcheck.com/Test-Go...e.85941.0.html

with full load and high screen brightness and other stuff on...

so it means on FULL LOAD the nexus 4 will extinguish its battery in little over an hour in theory.. if the phone does not throttle and reduce power consumption.. real life.. it will last 2 hours full load

... remember.. that is with the screen and other stuff included...

now..the galaxy s4 battery is 3.8 * 2.6 = 9.88Wh = 10Wh.. so if the tegra 4 alone will consume 10W.. without the screen... the tegra 4 phone will kill itself in

around 40 minutes.. witha screen.. if it has the galaxy s4 battery...

so.. that means that tegra 4 will have to be slowed down.. a lot.. for phones.. tablets might survive.. but the best use of the tegra 4 will be OUYA probably.. it draws power from the wall...

s4 pro on the otherhand is much more for phones

no wonder project shield has a 35Wh battery and needs a heatsink +fan !!!!!!!!!!!
