What is your Screen time on?

[Nexus 4 General] alrubenalves:
Ok, this can't be remotely normal...During this time I only had wifi on during maybe 4 hours. How is this possible?
[Nexus 4 General] Xaeons:
Interesting, yours and mine is similar (see attached)

I recently did a wipe and reinstalled my ROM and kernel, I restored everything in my Titanium Backup except the following apps:

Busybox free

Clean Master

Gravity Screen Pro

Gravity Box [KK]

Greenify

Lux (auto brightness app)

Nexus 4 Plug-In for Lux

ROM Manager

Touch Control

Trickster Mod

Xposed

I have no idea which of those apps cause my battery drain, though I have a hunch it's touch control. I'll try to restore each app one by one and see if my battery drain changes.

Some things to note:

I have tasks in Tasker that, on a set time, will continually scan the wifi networks (scan for 120secs, timeout in 60secs) and will send a text message if it detects my home/office network which can take up to two hours when I am commuting between locations. Dunno if it will drain the battery though.

I've only used my phone occasionally, mostly texting, some wifi surfing, calls, taking pictures at random. No 3g use.

No games, that's what my Nexus 7 is for

I'm using ART, no bionic or dalvik patches (dunno if that makes a difference)

Screen on time is 2h 59m
[Nexus 4 General] Webster200x:
My screen time was about ~4 hours and I only did some random pictures and some phone calls and I'm using ART.
[Nexus 4 General] pramyhoga:
That's incredible! Battery can stay for 3d. Didnt you used any apps within that period? Did you just put your nexus 4 at the table for 3 days?

Can people with great battery life tell us which radio they are using please?

Thanks
[Nexus 4 General] Hexxer:
Im absolutly unhappy with that device atm. Loading stops at 70% if device is in standby. I have to plugout an in on and on. If it charges the display changes (after 70%) from USB to AC to "not charging" random.
[Nexus 4 General] yfbc:
Wow I'm not especially handy with electronics but I had a few thoughts about looking into this, have you considered using the inductive charging abilities in the case?

I look forward to seeing how this turns out for you!
[Nexus 4 General] nyijedi:
Who gives a crap whether a phone gets good battery life as the result of having a huge battery rather than being efficient at power usage? It makes no difference to the user. Battery life is battery life.

And you talking about Android fanboys is ironically funny.
[Nexus 4 General] funkyblue04:
No, they were simply using it as a point of how crappy battery life in on Android.

Yes, "just saying." 4/4.7 = iPhone screen is 85% the size of N4's screen. 1440/2100 = iPhone battery is 69% the size of N4's battery

Web Browsing iP5 (LTE): 8.19h, N4 (3G): 4.15h

Web Browsing (Wifi) iP5: 10.27h, N4 (3G): 5.93h

I'm not even taking into consideration that the iPhone 5's screen is ~30% brighter than the N4's screen...just saying :rolleyes:

No. You go back to Android 2, and we'll keep pointing out flaws until Android's battery life is actually comparable to iOS in reality, not just in the minds of fanboys like yourself.

You being a fanboy is the only thing ironic here. In fact, for you to suggest I even like Apple's products when I'm using a Nexus 4 is strange. I love Android, but I will always bring up iOS's strong points. Apple is good at many things, and iOS is amazing. It's just not for me.

Now, moving on to your absolutely insane proposition. The difference to the end user is quite apparent. Allow me to demonstrate:

Do you understand? Not all of us want back problems as a result of carrying our phone.

Of course the ratio of the diagonals is not proportional to the areas or the rectangles. So I believe that your maths are not correct.
[Nexus 4 General] InvalidUsername:
I knew someone would bring this up. I had a good reason to do that. Yes, area is exponential when increasing the diagonal size, but power consumption is NOT. My point is that the iPhone has MUCH smaller battery, but gets MUCH better battery life.

[Nexus 4 General] powerwagon:
Not really sure what you're even talking about. I always hesitate to respond to posts that are just not factually accurate,but what the heck...I'm bored. I have owned the iPhone 4 and 4s, as well as multiple Android based phones (most recent being Note 2 and before that the One X). I won't compare the N2, as that is on another level, but the One X battery was on par if slightly better than either iPhone I owned...and that was with a MUCH larger screen with basically the same PPI as the iPhone. I get so tired of people such as yourself lauding the iphones battery life as amazing compared to Android. It should be...it literally does nothing. Not knocking the iPhone...it's a great device for some people, but the phone is basically a Jitterbug with more apps and better resolution...you can't compare that battery life to Android...simply apples and oranges.
[Nexus 4 General] pelmenept:
I am also experiencing not great battery life. Android os is eating the battery.
[Nexus 4 General] nyijedi:
Your example is flawed. The Note 2 isn't big because it has a big battery; it has a big battery because it's big. That is, it was designed with a huge screen as its selling point and the large battery logically followed. There are other phones with large capacity batteries that are smaller than the Note phones, and I've seen people suggest that their good battery life is "cheating" in some way, which is silly.

Moving on to posting some potentially useful information instead of comparing Android to iOS, there's a thread in the q and a section talking about an msm_hsic_host wakelock that appears to be causing big battery drain problems and appears to affect everyone when connected via mobile data rather than wifi. Hopefully someone can figure it out.

For those who have 4h+ screen on time, can i have your setting?

Any suggest for baterry monitor. I really need to find out where my battery goes.

Thanks!
[Nexus 4 General] skiesofwinds:
I know to know other people setting too, after 1 hour of usage, battery down to 88% already.
[Nexus 4 General] Markoni78:
Help please/nexus 4

Yeah, that.

I have wakelocks since 4.3

Now on 4.4.2 it is still present. What stands out is that although it sometimes wakelocks when I'm in one place I also noticed the wakelock starts when I change location - I go somewhere. Mobile signal is ok, and I'm on Mobile data. WiFi only at home.

Android OS is the process that keeps my phone awake. Easily drains the battery. For instance in 8 hours it keeps the phone awake for over 6 hours. 2min SOT and the battery is down from 100% to 60%!!!

Stock Nexus 4.

I have posted several posts here but so far I got no helpful reply.

If someone could try to help it would be greatly appreciated...

I just moved to CM11 latest nightly, Hell's Core 3.4.76, stock settings. dt2w, s2s from trickster mod enabled, as well as double tap status bar to sleep from CM11. I got 12 hours battery life with 2.5 hours SOT. GPS, data, bluetooth all off.

But now with slimkat battery is amazing...I think that is best to separate battery statistic with WiFi or only 3g.. Because everybody can reach 5hour of sot with only WiFi or playing in airplane mode but on mobile connection battery drains rreeeaaaallyyy muuch...I have no WiFi but my mobile plan offers me 20gb at the speed of 42.2mb/s so the real target is a ROM with best performance with 3g because now everybody has a promotion of 1 or 2gb of data mobile and we cannot light on and off everytime data >,> ...I advice to all that use data plan to flash the best ROM for reasonable autonomy with data only and NO WiFi..the ROM is slimkat..

Hi guys I like to switch between Roms and have tried many Roms and many kernels,

Is there a particular Rom or Kernel combination you use ? Or you guys undervolt the Kernel to get that much of SOT.

Hi

I'm not sure if this is a problem or if it's just how the nexus 4 is, I'm most of the time on 3G during the day because at my school they don't have wifi. And at the end of the day i can only get 2.5 SOT max, and that is with approx 10 hours of stand by.

My question is if this is normal behaviour for this phone with most of the time using 3G, also my setup is stock rom and several apps greenified + hells core kernel.
[Nexus 4 General] mymeatb18:
While in school how is ur cell signal? If u are not using the phone and have bad signal u should switch to 2g. At my house I have almost no signal while connected to 3g so when I'm home I switch to 2g and I have almost full bars. U can download llama I believe u can set it to change to 2g automatically when u get to school
[Nexus 4 General] insanezz:
Forgot to mention that, my signal is always good (3-4 bars) so that's not the issue i think. But is 2.5 SOT normal on 3G use then? with good signal?
[Nexus 4 General] draconianpr:
Are refurbished items that bad?

and with my current phone like what just happened it was at around 20% charge turned it off/on and now it says its at 70% not 3 mins into charging. Its been acting all wierd this past week and giving maybe 2 hours of SOT at most.

---------- Post added at 07:42 PM ---------- Previous post was at 07:34 PM ----------

Refurbished units are phones that have been returned, tested, and fixed. Sometimes they have problems. Just try charging it powered off it takes longer to charge. Best time to do it when u won't need the phone until it's done.

Run the batter till almost dead 5% is fine

Power off

Plug in charger

Wait about 8-12 hours

Power on full to check charge status and leave it charging till it's 100% if not yet. If 100 then unplug and good to go

I'll explain it a bit more : Ussualy my typicall school day starts around with 1 hour approx of listening to music (offline) and checking google+, xda, twitter, whats app etc. Then when i arrive at school i barley use the phone, just sometimes sending a whats app. Then around 5 pm when school is over im again listening to so music for around 30 minutes and again checking social media. Then when i arrive home i ussualy have around 15-20% battery left with 2-2.5 hours of SOT. This is all on 3G, and when the phone is in stand by its using 2G (using gravity box). And i don't make phone calls, i maybe call once a week so.

In my opnion this is really bad battery life.. Or am i wrong?
