Battery life in comparison to iPhone?

Anyone here able to compare the battery life of the Nexus, to an iPhone 4 or 4S (a 4S WITHOUT the battery issue)? I've gotten amazing battery life on my iDevices. I can't imagine getting worse battery life again like I used to on my other Android phones.
And also, what battery solutions could I use if I want a bigger battery? Any extended batteries + covers out there I could buy? I don't just want an extra battery to replace during the day, cuz that'd be a pain.
Thanks in advance!
edit: I'm not a light user - I might go as far as to say I'm a heavy user.

not sure on the GSM version, but I can promise you the LTE model is going to be complete crap compared to an iphone.
on my old iphone 3gs, I could watch like 4 movies & still browse the net for a bit before the battery died... on my thunderbolt & rezound I could watch like 1 movie & then browsr the net for about an hour.
even if you disable LTE(or go into airplane mode for that matter) its only going to help slightly.
you will have to invest in an extended battery unless you are someone who does "light use".

Gsm version is completely crap. The one who says it is OK must be a newbie and does not have a lot of experience in smartphones.

My battery life is just fine, and I'm hardly a newbie. Perhaps you don't have your phone set up in an optimal way. You should have no problem getting through a day of normal use, and you can get through a day of heavy use without charging. With 3hrs of talk and 3 hrs of screen time (auto brightness), with push email, bluetooth, wifi, and gps on I was able to still get 15+hrs of battery life before it got under 10%. Not sure how you have your phone set up, but my battery life is just fine.

^absolute bollocks.
I'm not a newbie and have both devices. The battery life on the GN is absolutely fine, yes the 4s is better, particularly when on standby, but I can get a good days use out of either phone.
One thing that I found annoying with my NS was the time it took to charge, the GN is far quicker and similar to the 4s.

I've had 5 Android phones so I know that the GN battery life is better than most. I easily get a day of heavy use out of it.

Battery life its significantly worse than iphone 4 and galaxy s2. I've had a number of android phones and galaxy nexus has worst battery life of them all
Sent from my Galaxy Nexus using Tapatalk

Wouldn't know much about the iphones, but compared to my previous phones (Nexus s, and a HTC Hero before that) the Galaxy Nexus is NOTICEABLY BETTER. I have no problem going a full day on single charge with heavy use. Or two full days with light use.

these topics are useless. galaxy nexus is a dev/debug phone.
i spend more time with it connected to the computer than anything else.
why are people comparing android devices to apple devices. it's just plain useless.

Actually battery life is really good the issue comes with how fast the screen drains the battery. Considering smiled power consumption is based on lit pixels and there are a lot more here than the s2

Comparing to iphone is not useless at all since that is the alternative many are considering out coming from. Just because you use the phone mostly for development doesn't mean others do.

I have the following:
GNEX GSM
iPhone 4 (GSM on ATT) - work phone
iPhone 4S (GSM on ATT) - wife's phone
The battery life on the iPhones is about double what the GNEX is, easily. I can do two days between charges on the iPhone even with normal use. The GNEX requires charging every night.
Do I care? Nope. I charge my phone every night anyway and always buy spare batteries.
Who in the world is away from a plug at night? Do you live in the woods?
I just don't see what the big deal is. If the battery died in 4 hrs on standby, I can understand. But it easily cruises through the whole day.
That's fine by me.

It's more helpful if you also post your screen time and Android OS stats. That screenshot really tells us nothing without that info.

Yep. For those who complain of battery life, I bet you are running lookout mobile, skype, and a live wallpaper, lol.
Download "colors" from the android market, set wallpaper to solid black. Don't run junk apps that are on 24/7 and watch your battery last all day long.
Simple, really.

I know the battery consumption on this phone freaks me out. I am actually considering selling it and return to HTC...Oh man htc saves my life every single time. Samsung needs to learn.

Def worse than my iPhone 4. In my case I decided to stock on chargers rather than becoming a lighter user

Battery Life - screen on time & battery conditioning

Firstly let me say I'm a long time lurker of XDA, I don't often post but rather keep quiet in the shadows. I've owned many handsets (Including the Inc. and TB, meaning I know bad battery life) and this has always been the site I go to for hacking and general information.
I don't expect definite, for-sure answers. I'm just seeking some advice on this, I absolutely love this phone and a Nexus on Verizon has always been my dream.
Secondly, I'm not posting here asking why my screen uses over 50% of the depletion on my charges, it is supposed to, I know that. I see many threads asking about that, which is why I waited to post not wanting to ask what has been already. But I am asking about my case specifically, and want input.
The main thing here is the amount of screen on time I am able to get.
I have had my GNex since Saturday afternoon, when I bought it the battery was dead and I fully charged it, the first day I used it mostly while plugged into AC, using 4G to install my apps. Since then (the last two days) I have tried depleting the charge almost entirely before charging, shying away from charging mid-depletion. I have tried using CDMA mostly (my area has just marginally good 4G), hoping I could stop some of the bleeding, but to no avail. I should also say I yesterday for the first time threw a custom ROM/Kernel on and that seemed to help marginally, though in truth I don't see that really changing the screen power consumption.
Please take a good look at both screenshots, as said I care nothing about the %.
(I am aware there is still 13% remaining on my charge, but even so this seems just crazy)
In the first screenshot at the bottom it's apparent this isn't a huge amount of screen on time.
I would kill to get 4 hours of screen on time with this thing, heck even in the area of 3, but it doesn't seem to be in the foreseeable future as it looks now. I can get out 2 at most to this point, and that is on almost entirely 3G/WiFi with light/moderate data usage.
I really need to ask. Do I just need patience to let this battery break in? I hear some say this can be a week-long thing, but shouldn't I see some increase by now?
If not, do I seek out a replacement battery or could this be an actual defect of the AMOLED drawing more than it should?
Thanks for your help!

There were quite a lot of awake time during screen off if I look your stat.
Thats your problem.
Too much sync?
Mine can get up to 3 hours and 45 minutes screen on time, span into 2 days stand by, gsm version.

Good point, looking into playing with sync in settings and JD.
But while that accounts for the drop during the 10hr overnight period (20% of battery/83% of time), I still feel the draw during screen on (80% of battery/17% of time) is just insane, even given the AMOLED.

Maybe its a rogue app running in the background making the battery drain real fast. Try wiping and running the phone normally without restoring your apps and see if that will improve. I'm having the same problem as you but with the GSM version. I'm looking through my apps though.

Here are some of the usual suspects:
- Facebook for Android app (uninstall it and replace it with Friendcaster and change the frequency of update t less often will do the trick)
- Accuweather widget or any other weather widgets
- Whatsapp
- Viber
- Latitude (google maps) - Login to Latitude and then ensure you select the option where it does not report your location and then sign out of Latitude.

Honestly, I have the GSM version and I've rarely gotten over 3 hours screen time. It's the screen. The battery life sucks, so you'll have to just ABC (always be charging), at the desk/sofa/car.
What I really want to ask is how you got the battery percentage inside the battery icon?!

This is also my exact problem. I can get great life if I don't touch the phone. Every time I use it for a few seconds, that's 2-3% gone. Browse the internet for 15 mins? Forget it, that's 10% gone at least.
I guess it's just the price to pay for such a gorgeous screen.

The custom ROM I'm running had it as the default icon: AXI0M 2.3.

What is your total screen on time during those charges?
The only app in that list I really have to check is latitude. Doing so now.

I think op should stop playing wind up knight in his sleep. Case closed. Just kidding. But seriously, probably got something using up cpu cycles when using phone and not using it. If i dont play any games, i easily get 4 hours screen time, and got 5.25 over the weekend.

When I flashed this ROM I purposely left games out when setting it back up, the only one is Drop7 which I purposely make sure gets killed when I'm done. All apps which sync I have either at minimal amounts or off entirely.

Are you in north america? Try ugkk7 radio maybe? I am in the usa and xxkk6 was ok, but since i flashed ugkk7 reception is excellent. Oh wait. Youre cdma version. I dont know if the same applies. I do know radios designated UGxx# are north american.

you could install CPU SPY to see if your device is going in deepsleep, I had a problem that one app was using most of the time 350mhz and was using my battery very fast.
after that i found the app with battery monitor and disabled the app to see if the problem was solved, and that was the case, and i have now a battery life from more then a day instead of 5 hours.

I can get 3.5 hours of screen on time spread over ~36 hours or so on the GSM version.. if LTE is on I would assume around two hours of screen on time was normal for a Verizon version just because of how LTE is but it did look like your CPU was awake a lot as well so also it could be a rogue app, not necessarily a game.

Will give that a try. Like mentioned though almost none of that time was 4G enabled. (Maybe 10mins of that first green section.) The slope is just as steep.
In truth this was a fairly data-light charge.
Could it be the rogue app would actually sap battery only when the screen is on? Even though there is wake time where there shouldn't, that isn't the main area of drain.

Galaxy Nexus Battery Fix

Hi,
I just got my Galaxy Nexus, flashed with AOKP build 18 and i gotta say that the battery life is unacceptable. It drops 10% in less then 1h while the phone is sitting there doing nothing. Wifi, bluetooth, location services, GPS are off. All background apps closed.
It lasts about half the time my iPhone 4 does and it is a year and half old.
I see some people showing examples of how their battery last for more then 20h but all these are BS tests as they leave the phone on standby all day or have some very light usage.
Is there a real fix for this? Am i forced to drop another 50$ and buy Samsung's 2100mh extended battery?
btw i tried setCPU also to lower CPU to minimum when in standby but doesnt do much. I want a solution that will enable me to use my phone, not something that makes it last 40h in standby and then kills it in 2h when i use it.
please help!

So everyone that posts four hours of screen on time is bullshitting? Did you know the first 10% isn't even that accurate? If you're on Verizon turn off LTE. If you're on GSM and you don't get three hours of screen on time you have an app that is killing your battery. It is as simple as that.

Try toggling Bluetooth on and then off, then grab CpuSpy from the market and check out if the CPU is pegged at a certain speed.
Some builds of ALL the custom ROMs have had issues where the phone wont sleep correctly, high %-age of Android System process, etc.
I disagree that its silly to talk about idle time on battery, because idle time is the closest we can all get to apples to apples comparison. We all USE our phones differently, the closest we come to using them the same is when they are just sitting there idle (not quite exact because some people sync data, some people only have 3G, etc, but a lot closer than person A playing games for 3 hours at a clip vs person B browsing for 3 hours)
I *still* havent seen anyone come up with a template like setup to report battery life. Like you said it does me no good to know someone dropped 3% "overnight" without knowing how long "overnight" is, if they had 3g/4g/Wifi enabled or even disabled completely, sync on/off, etc.
Personally, Ive seen 1.5%/hr drop with my phone idle. Running AOKP b19, LeanKernel, interactivex governor, undervolted (-75 mA at each level from 180 mhz to 1200 mhz), 4G on, BT on, GPS on, sync on (1 gmail account).
I imagine with all that stuff running 1.5%/hr isnt half bad. Screen on time isnt incredible but its not bad, but again my screen on activities can (and probably will) be different than your screen on activities so take that with several grains of salt.

It's not the first 10%, it's all the time.. it drops for about 10% or more every hour. Less then 3h of screen time.
I'll give cpuspy a try and see if some app is killing my battery.
I used AOKP rom because most of the people in the thread were saying that rom fixed their battery issue but for me it made no difference.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV

It's actually 2000 mAh not 2100 mAh.
You can use a custom kernel such as Franco Kernel. New version came out today and includes more battery improvements (according to changelog!)

As you can see, if my screen is on the graph drops, when it's off the graph flattens out and the battery barely moves. I used to be sick to my stomach of the battery life until I realized it was because I wouldn't put the phone down and always had the screen on thus killing the battery.

Just a word of advice. Whites consume more power on AMOLED screens. You'd probably maximize your battery a lot more if you went back to a "Ice Cream Sandwich" feel or at least apply a black themed MIUI.

I had something similar and it was recommended to me on these forums that I log out of Gtalk.
Before people come out and say it makes no sense - it doesn't really matter if it does or not - it worked for me. I get a full day out of a charge now, which doesn't really matter because as someone said above it's all relative. What DOES matter is that my phone is now sleeping properly, so the battery doesn't drain when the phone is idle. That's the part that wasn't working on my phone.
If you feel so inclined, give this a try and see if it works for you. Just log out of all Google talk accounts and see how your battery life is - you'll know within a day if it's helping.

Have you flashed the new radios yet?
You can also try different kernels and see which one works best for you.

not quite.
can i preface by saying that there are two types of Gnexus's out there? the SCH-i515 (CDMA/LTE Verizon) and the GT-i9250 (HSPA+, AT&T).
The 2000mAh is for the HSPA+ version
The 2100mAh is for the LTE version.
i see a LOT of bad advice on these forums here.
my best advice to you (from one Verizon Nexus owner to another), is to keep at stock 4.0.2. Root it, and apply a custom kernel. Only apply custom kernel if you feel that you're still not getting decent battery life for a whole day on 4G stock ROM/kernel.
As far as I know, Verizon Nexus owners' max on-screen time with 4G enabled all day is about 3 hours MAX, and thats if you disable everything else but LTE, with very low brightness settings, and on extended battery.
imo, the next 4.0.3 or 4.0.4 update hopefully will mitigate some battery consumption issues.

4 hours screen on time including 21 minutes using gps for Sygic Navigation is not bull****. Stand by for up to 61 hours, easy.
And I was using the phone extensively for web browsing, facebook, gplus, xda, games, etc.
All with stock rom and stock kernel, extended battery 2000mAh, gsm.

You were on wifi the entire day.
You are using the HSPA+ version of the Nexus. HSPA+ version gets better battery life.
Try being on HSPA+ the entire day with wifi disabled. you will not be getting 4 hours of battery life on-screen time.

Most of the time I was on wifi, but not all.
But fair enough, I will test on 100% without WiFi. However, we don't have HSDPA+ unfortunately. Only HSDPA or 3G.

I went 13 hours yesterday with LTE on all day and had almost 4 hours of screen on time. I'm running stock ICS unrooted and all of my sync stuff is enabled. I'm also using the extended battery.

would like proof. afaik, its impossible to get 4 hours of battery life with LTE enabled all day.
sounds dumb, but are you sure you have Verizon's GNexus? Your profile shows an AT&T carrier... otherwise you should probably update it.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.

I think the Kernel is what makes the difference. It seems to be the only difference i see between myself and the people like you have a reasonable battery life.
which one do you recommend? And i'm a noob at this so could you point me to a thread the explains how to flash it? If u cant its ok im sure i can figure it out.

I've got to break the well spoken rule about battery life threads.

After long being one of those people who would never post a thread with bias questions or answers.
It's come to this.
I long for the battery I had from ICS, I never got less than 4 hours screen on and 16 hours standby together.
The best I got was right at 5 hours screen on with 18 hours standby.
All with wifi/3G only, very little to none 4G, it's fine with me.
AOKP M6.
_____
Every single ROM/Kernel combination since I've moved to JB has provided me with just......crap......
AOKP, AOKP kangs, CM, Liquid, CNA, and Eclipse along in different combinations with
Faux, Lean, stock, 007, TinyKernel, and Trinity kernels.
It does not matter what combination I use.
I can barely get over 3 hours-ish screen on time with about 12-18 hours standby.
Now if I use the screen less than 2 hours, I can get up to two days standby, which is nice but not the overall complete usefulness I had.
I know battery has long been an issue for many of us, but I see people in threads talking about their 2 hours of screen on time like it's amazing when it's awful, especially when some of us, could, and used to get close to 5 with stock batteries or 2100 extended (mine)
If you're using LTE all the time, only 2 hours screen on is justified because it should be common knowledge what happens.
Point of the thread is this, I want to know, those on JB with stock or 2100mAh battery and can manage 4+ hours screen on and still close to a day of screen on, what's your secret? Every detail, spill them.
Is it our fault or are we just in a down time of battery efficiency in the ROMs and kernels?

There is no secret, jb is crap when compared to battery usage on ics

Couldn't figure out why my battery life was so poor the for the last month or so. Good to see I'm not the only one with the problem.
AOKP ICS with Franco kernel gave me amazing battery life. Jelly Bean not so much.

I personally believe that anyone getting more screen time than you (this goes for anyone) is:
a) Using their phone in an environment that is less bright than you (indoors, on the bus, in the subway)
b) and / or not syncing as many things as you / not as often as you.
Reverse the above for people getting less screen time than you.
This is the truth of the matter.
Personally, I get 2 to 3 hours to 3.5 hours of screen time on JB, depending on usage.
4 hours if I read in bed at night.
Edit: Kernel / ROM be damned, maybe it'll make 10 to 15 minutes worth of difference. NOBODY has presented scientific proof of any ROM/kernel being different from any other. It's always "oh yaa best battery life ever with this rom". It's just noise and cherry-picked screenshots.

I usually get at least 1 day worth of charge. My set up is pretty easy tho. Since I am in front of a computer 75% of the time , gmail sync is turned off, twitter is @ 4 hours, Facebook set to never with location turned off. Phone gps and location are also turned off unless I M walking towards the bus stop. I don't need to be checking my phone every 5 minutes so my useage is pretty stable and predictable. I wonder what you guys are doing to make the battery die so quick? If your usage patterns are pretty high with checking email 100s of texts and lots of twitter and Facebook well yeah I'll die quick.
Also I seem to get the same results with custom kernels and stock. I have little experience with CPU controls and and such so maybe setting a lower frequency will help?

Battery can be related to many causes leading to user error. I never used ICS on this phone so I honestly have no idea how great the battery was.
Google now, project butter and many other optimizations are to blame yes.
Depends how much you use it and what is going and the vary of networks going on and off and switching. I can normally pull off 3-4 hours of near heavy use. My droid incredible could only get at least 1 hour max. So maybe it is me but the nexus is a godsend for me.
Leaving the governor at interactive with low max and undervolting will help battery and a specific kernel. I can normally roll with 0-10% brightness and have all networks running and syncing.
I'm tired and ready to cook my tacos I'll be back later with more input.

STOP overclocking your phone (even to 1350), under clocking exists you know.
STOP using interactive governors.

Try this...
I have an old Android phone that my boy plays with...so I turn the cell radio off & have it on the wifi signal only. Even with him having the screen on for hours & hours (usually playing games), the phone will stay on battery for almost 4 days!
Turn your cell radio to airplane mode & then turn on wifi only...mess around with it, play games & see what the difference is. When I have a Sprint signal (usually junk 2g one) at home I get poor battery life...when I hack the PRL to choose a 3g (better) signal I get twice the battery life...
I've seen other battery life threads where the signal is a MAJOR factor & even with a strong 2g signal the 3g is probably better at not wasting battery. (4g is a whole other story)

I've found 4 things that almost double my battery life
1) Google Maps: huge battery drainer. freezing it doesn't help either, it has to be uninstalled. Mapquest from the play store is a decent battery friendly alternative. or if you really need gmaps, copy the .apk file and install it when needed, then uninstall afterward.
2) Push Email apps: i.e. Yahoo mail app, Gmail app... use the built-in email app and set the refresh limit to every hour.
3) 3G/2G: when your not using data, put it to 2g networks only. huge battery savings especially if you're somewhere with a weak 3/4g signal.
4) NFC/WIFI/GPS : turn them off if your not using them (obviously)
your results may vary, but doing these things did wonders for my battery. I average 23-26 hours with 2.5-3.5 hrs screen on time. before that I was getting 14-16 hrs with about 1.5-2 hrs screen on

Well, Switching 2g/3g is pretty battery draining, too. So better be sure you don't use 3g networks for a while. constantly switching just to be a minute or two at 2g just drains more
Turning of WiFi is pretty obvious but NFC and GPS shouldn't take any battery juice if they arn't in use... Someone tested it and could proove, that gps only uses battery power if it's searching for a connection.

As you can see, you basically need t neuter your device and constantly worry in order to get 'great' battery life, lol.

Before we all jump to Nexus 4, are we sure Google has killed the battery vampires?

I've had the Galaxy Nexus LTE for nearly 11 months on Verizon. I've done what I can to stem battery drain. At some point, I just gave up diagnosing the problem and started carrying 5-6 spare batteries with me. Some people claim one day's use; others report the same problems. I think it all depends on how we use our phones--eg do you take a lot of pictures--and what apps we have installed. I use the phone hard but not that hard. Sometimes the phone will burn the battery just being in the pocket.
I don't want this to be another Galaxy Nexus battery life sucks thread. What I want to know is whether the battery drain problem will be solved before we consider moving onto phones running 4.2.
Some of the drain is due to the terrible LTE radio. Phones with integrated chips have much less hardware drain.
But about the software drain? When I run GSam Battery Monitor, the number culprits seem to be Media Scanner (Server?), acore processes--contacts, user dictionary.
I've dialed down or turned off syncs as far as I reasonably can; are rogue apps causing problems or is the OS too easy to trip up?
If you search http://code.google.com/p/android/issues/list for "media battery," you see a lot of bug reports about the problem.
The Google Android team doesn't seem to care about these problems.
http://code.google.com/p/android/issues/detail?id=11731#c5
"I'm only posting this here for my own amusement. My track record with Android bug reports is that Google ignores them for 2 years and then closes them without taking any corrective action. Good luck everyone."
Here's a typical bug report from mid-2011, that is still labeled new and unassigned:
http://code.google.com/p/android/issues/detail?id=18115
4.1.2 has the os drain:
http://code.google.com/p/android/issues/detail?id=38720
Going into 4.2, how do we track these issues and see if they are getting fixed? I'm not a dev... The only way we can see the 4.2 source and commits is to clone the repo using git? Is there a friendly web interact through which we can see the changes?
Do we wait until 4.2 is released and see what defects are reported on the issue tracker?
Please don't let this be a typical battery life sucks thread, where people will
1) complain that they also have bad battery life
2) complaint that they have great battery life and don't see these problems
3) suggest debugging these problems with CPU SPY, BetterBatteryStats, etc
4) suggest fixing these problems with .nomedia
I want to know how we as users can track what Google is doing or has done to fix these problems in 4.2, so we, as Android devotees, can have faith in migrating to those devices.

Any Tom, ****, or Harry can post issues. Most of the time they don't have the technical knowledge to even know what a bug is. Don't confuse Google not caring vs. Google not willing to accept a ticket caused by something out of their control.
As for your case, you have a Verizon Nexus. They ALL suck on battery compared to other devices.
You say you don't want this to devolve into a typical battery thread but it will.

no lte in the nexus 4, sounds like they chased off the battery sucker to me.

I'd you're using your phone as a laptop, it's time to buy a laptop. Otherwise, the turn if syncing for things you use once a day. Actively using data (especially over LTE) with a large screen burns battery on any device. If you are burning battery in your pocket, you either need to sync less or identify the rogue app that is doing the work. And Google does use the bug reports to make improvements. A recent bug in Chrome removed names from the shortcuts in the bookmarks bar and it was fixed within a week. Android rakes longer due to the wide spectrum of devices and overall update process. Bugs in an OS are a different beast than bugs in a browser.
From the sounds of things, you will have battery issues on any device.

Go by the evidence. The Media Server / Scanner drain problem still exists in 4.1.2

Complaining about battery life on an LTE device is like dropping a 600HP engine in your car and complaining about your gas mileage going down.
So lets say an LTE phone has an enormous battery in it, this might give you "respectable" battery life... but take that same huge battery and put it in a GSM phone and watch the battery life go from "respectable" to "incredible".
If battery life is what you need... you might consider going GSM. With heavy use I usually end up at about 30-40% at the end of the day...
Of course, as stated above, the media scanner bug is still there... but from my experience, LTE is the biggest "battery vampire" by a landslide.

I can't wait to see how many "battery life sucks on N4" threads are created.

First, turning it off at night, makes your "4 days" statement entirely false, automatically. Second, 1 hour 20 minutes screen on time is terrible, even for a known battery sucker like the gnex. Third, the only thing might slightly warrant a pardon for that screen on time, would be the fact that you did get over 2 days on it, if not for Fourth (and finally) the fact that your phone clearly shows that your didn't use it at all.

4 days of my use, where is there false information? Still on the same charge, 1 hour 41 mins now. 61 hours with real world use is not bad, especially since despite you seemingly knowing how I use my phone, I was using it for texting, a few calls, I used google maps, updated some stuff and other random crap. A lot can be done in an hour and a half.
And finally, the entire point of this thread is the android process sucking up battery, which is why I posted a picture showing the contrary. How about you find something credible to ***** about.

Maybe if you stop using that ugly, bloated, stupid ROM your Android process usage will be reduced.
