Alright so my display on the nexus is always using anywhere from 49%-53% and I have it on the lowest brightness setting. How do I get it lower? any sugestions? Also, I got the phone on christmas and the most battery I've been able to get is 12 hours using the phone not at all.
The display on a phone like this will almost always be the highest percent user of your battery, unless you never turn the screen on.
The more relevant question is how much Screen Time On are you getting out of a single charge?
Maybe you can open you phone and disconnect the display (have a look at http://www.ifixit.com/Teardown/Samsung-Galaxy-Nexus-Teardown/7182/1) it may help. Hopefully voice control works fine
Remember, its just percentage. The lower your screen % the higher everything else is drawing. You have to expect the screen will always be the biggest drawer. Better to go by run time, how long you are getting out of your battery before it dies. You still have quite a bit of life left at say 20% battery.
Turning down brightness is the most you can do, other than being proactive about turning the screen off when you are done and not letting it time-out.
Eventually new software will help with battery life; using custom roms with later releases has improved consumption. Also remember to turn off wifi if you are not using it. Big hog

When using my phone, the display is always the culprit for battery usage. That's normal.
If you don't use your phone heavily and only get 12 hours, your problem is elsewhere. What do your battery stats say (settings -> battery) ?
edit : typo
Isnt there a thousand threads on the internet about screen % and battery life
The display will most likely always draw the most power but you can do two things. First you can lower the brightness, and second, you can use black wallpapers because super amoled screens use the least amount of power when displaying black

This seems to be incorrect from a test someone did on this forum.
Basically on lowest brightness - white and black appear to use roughly same.
On max setting, white killed the battery in half the time that black did.

No, but if you have a choice to extend the battery 1%, by simply choosing something as simple as a darker wallpaper, I see no issue with the advice. Everything you hit the home button you'll see the wallpaper.

I prefer having a nice colorful wallpaper than a black one that would extend my battery a few %. It all depends on how you use your phone and what are your needs.
Today I've used my phone heavily (web browsing and google reader, gaming, bought a new bluetooth headset and played with it, 30' GPS with Google Maps, etc) and I'm at 38% after 17 hours, with an animated wallpaper. Not too bad...
This is my battery status from my display. Its not on the lowest setting, maybe 10% at most.

It's like every incarnation of a phone with an SAMOLED screen shocks people. I don't know why. The screen sucking juice is about the biggest, "well duh" concept out there.
It is what it is. All ya can do is live with it, or get a phone with an old TFT display.
unremarked said:
I was hoping someone was going to explain how to read the percentage but apparently no one is going to.
First, and I'm going to use the numbers from your last screen shot, your screen is not using 42% of your battery. Your phone has discharged 12%(meaning that you're at 88% of full charge), and 42% of that discharge went to your screen. 58% of that discharge went to the rest of your phones system. Does this make sense?
The screen will always have the highest percentage because it is the main way you interact with the phone. If something was above the screen, then something is wrong. Further the percentage will always change as some things are used more or others used less.

There are reverse LCDs that use power to make white, but virtually all LCDs need backlighting, so the tradeoff is less important. Also, LCDs really (theoretically, at least) only use power when changing state. As long as the display isn't changing, the power usage is virtually zero.
All that said, reducing the brightness on my gnex makes a HUGE difference in battery life.

That's roughly what I will get with brightness at about 70%. The battery life is not great on this phone, PERIOD. Just enjoy the phone and charge it when it needs to be charged (it charges up really quickly).
It is amazing how many people have 3-4 hours to be spending on their phone a day.
Well I might as well finish off any questions since this was revived
LCD screens use power even if the pixil was black. They use power even if the image is not moving.
Amoled screens (our phone) are the same as LCD except that black pixils don't use any power.
E-ink screens are a different matter they don't use any power when nothing is changing and they only use power at at the pixils that change to display the content. The issue with this tech for general display use is the refresh rate is a Max of 10 fps on the new displays. The new color displays are washed out.
The reason our battery life is like **** is because of our large displays and that poor battery does not have enough power to keep them going. They are the main power suckers of all electronics and our CPU takes a fraction compaird to them.
These kernels help by being more efficient with the power and undervolting the CPU giving us a idle time of over 20 Hrs.
The reason people can push 5 Hrs screen time is because of these black themes helping the screen use less power. Its the reason black themes are soon popular. In general your lucky to hit 3 Hrs its not that its defective its just how it is
I hope this clears some things up

I see several threads talking about battery life but no one has shown their actual "screen on" time which is what really counts, as it tells us how long have you actually been using the phone for.
I am starting this thread in order to try to collect a more accurate representation of how long the Galaxy Nexus battery lasts, using screen on time as the biggest factor (which it is).
So, in order to find this out, owners of the GNexus, please go to the battery stats section and tap on the "Screen" line, which will tell you for how long has the display been on.
How long are you guys seeing the display last until the battery is really low?
As a frame of reference, I remember seeing about 6-7hrs max on the Galaxy S2, when used with mainly black backgrounds.
I'm interested in this too. While each person's usage will differ, a couple of figures/screenshots would help gauge how much more battery the large screen uses as compared to phones some are planning to switch from.

From my testing using 3g browsing the phone lasts at most 4 hours with screen on. This is at manual 40% brightness since automatic brightness makes the screen too dark for me. Battery life is definitely worse than galaxy S2 in fact it is so bad that I an considering returning the phone.

Please go back to battery stats and tap on "Screen" to know exactly how much time has the screen been on for. That is what we really need to know.
The standby life of the phone with the screen off is fine. However, with the screen on it gobbles power and lasts 4 hours max. Here is screenshot of my usage today:

Guys, thanks for the screenshots but please tap on the Screen percentage bar to show actual screen on time. That is the statistic we need.
Here it is, it is actually worse than I thought the screen was only on for 2h 27min:
I did manually set the brightness to around 40% since as I said before auto-brightness is too dark for me.
Thanks, that's what I needed. It is indeed pretty bad, as I expected SAMOLED is still an awful choice for web browsing.

That's the case with all screens. Until battery technology gets an update (in two to four years time) we won't see a better performance without extended battery.
That's just how it is. It never bothered me on HTC Desire. During one day I don't use the screen more than three or four hours in total. At best I use it one hour in the morning during the process of getting to work and one hour to get home and then an hour in between during calls, checking news or reading e-mail. I personally am totally fine with it, it is not meant to replace a computer or a tablet that both have much better power supply simply thanks to their size.
my screen has now been on for 1h 32 mins
(total 8h 34 and now 64% battery)
shame......we need more people to chime in. I've heard about better battery life than a few hours of screen time.
Only reason why i like iPhone....can browse internet for hours and hours and hours and GPS
I also do not usually use the phone more than 3 - 4 hours a day during a weekday. However on weekend or when travelling I do need a longer-lasting phone. I was hoping it would last as long as Galaxy S2, but unfortunately it doesn't.

Not exactly true. AMOLED and SAMOLED screens have different power requirements depending on what is showing on screen. Most websites have a white background, which for AMOLED screens means almos 3 times as much power usage as a standard LCD screen. So, technically LCD screens are better for browsing as their power usage remains constant no matter what you are looking at.
Just check out Anand's battery performance chart:
The iPhone wins because it has a smaller screen which is also IPS based and therefore very energy efficient. As you go down the list you'll see the only SAMOLED screen with "decent" performance is the Galaxy S2, and even then it's almost 3 hours worse than the Atrix, for example (granted the Atrix has a larger battery, but not by much).
What saddens me is how newer devices are targeted almost as mini-tablets thanks to their huge screens yet by using Super AMOLED screens they are limiting what you can use them for. The Galaxy Note barely lasts 3-4 hours browsing according to some tests.
I hope to see some more positive results soon, because as it stands I'm not happy with what I'm seeing from the Nexus.

On my Nexus S, I set the brightness to 8%.
And that's enough for me.
I have auto brightness toggle ready at the home screen if needed, for example during outdoor use.
All in all, I use my phone mostly indoor. Super AMOLED at 8% brightness is more than enough
Sent from my Nexus S using XDA App
For me it never really depend on the phone it was mostly something around 3-4 hours.
What counts as well is how good the drain in the deep sleep state is.
It wasn't a problem to survive 24h with my SGS II but with Desire, which is what I'm using now, I wouldn't bet on it.
ics just doesn't seem worth it...
this makes me sad
i've had the atrix since it's been out and i've really been hoping to upgrade to something just as solid. for all the complaints i've read about the atrix i figured many other phones were better yet i go read on other phones and find the atrix wins out all the time. i'm running cm7.1 (not nightlies) and not o/c or u/v and my phone sports screen times over 7 hours. i can play any game. the phone has very decent ppi thanks to qHD on a 4" but the pentile sucks. gps is spot on...ok i could go on forever, i guess from what i'm reading, i'll just wait till the next 720p screen comes out with maybe like tegra3 next year, hopefully it'll come with lte by that time which is really what i wanted to upgrade to. 4.0 ics just doesn't seem worth the 3-4 months i'll have to wait vs the sacrifices i'd have to make...
that's pretty bad i am considering the nexus but that battery stats damm worse than de gs2
really unsure what the concern is. id never have got this much out of my Desire-
51% battery
screen 56%
screen time 2h
and thats with a fair amount of tinkering now.
I LOVE the Galaxy Nexus, but the rate at which the battery discharges is just ridiculous. I'll use the phone for 15 minutes doing things like Twitter or Web Browsing, and it'll discharge 5% in that time. To me, that is horrible. I'm being really conservative too. Throughout a day I try not to play videos, games, or anything else intensive because I know it'll ruin my battery life. Even on standby it discharges 5% in an hour. Typically I lose about 10% an hour and my max has been 12 hours so far.
I have auto sync turned on and keep the screen low when possible. I NEED auto sync on because of the nature of my work. Compared to my iPhone 4S battery is downright pathetic.
Today my usage consisted of one phone call, a few text messages, lots of Twitter, and light web browsing. Nothing too crazy. Again I'm being really conservative with my usage whereas on my iPhone I can do whatever I want and not worry. I'm just not seeing how people are getting 15+ hours and claim heavy usage. I'd love to believe that! The battery drains so fast during normal usage it may be a deal breaker for me.

It sounds like your definition of light usage is wrong.
I wouldn't consider heaps of twitter and some web browsing light usage. I would consider it moderate usage, in which case you seem to be in line with everyone else.
I agree with you in that the battery life isn't quite what I would have liked. Ideally I wouldn't have to worry about battery at all, and I'd be able to play games and browse the web as much as I like, but for normal usage it's fine.
The next Nexus though, man, that will only have to be charged once a month. I can't wait.

Twitter hardly taxes the processors at all. Refreshing it every so often should hardly take any battery life at all. Web Browsing I can understand, but my total time browsing today probably amounts to 10 minutes total.
I wonder how much of the drain is attributed to the 4.65" screen. It's a monster.

People using a G2x claim to get a day and a half... I'm lucky to get out of work. Push email for work is to blame I think. I get tons of emails (100 a day) and I think its taxing. From your pics, the screen used over 50% of it. That's a lot.
Sucks.
Also make sure your aren't turning on the screen every 5 minutes to check the status. Since your coming from an iOS, are you closing apps properly (back = close, home = minimize).
I'm not saying your crazy but just saying.

I had the same thing happen with the Nexus One. The battery wasn't that great but, got better after a few charge cycles.
I've never had a Android phone that could match the battery life of the Iphone. I can sit the iphone down at night without putting it on the charger and, if it's at 100% it will be at about 90-95% when I wake up. I did the same thing with my Mytouch 4G and, it was at 15%
To the OP, I would recommend keeping a charging cable with you when you out and about especially in your car. I've had car docks with a few of my android phones and, always keep the phone docked when I'm driving somewhere. It really helps.
What you also need to remember is this is the first release of ICS and is still in development so battery life my be improved in the next update. Like you mention iPhone4S there was massive battery leakage in the first release of IOS 5 which Apple apparently fixed in the newest update.. So maybe in the next update we can expect some bugs ironed out.
Used to only have ONLY 2-3 hours screen ON on my Vibrant so I know how SAmoled looks like.
I know iphone battery is good, but you need to consider the screen size too..
Get a spare battery with your "light usage", but I am thinking how much would it cost becoz of the NPC antenna.
Too good thing is, unlike iPhone, you can buy a spare battery and carry it with you.
3 hours of screen use is what the problem is. That is a long time. I wouldn't complain about that at all.

I already said I didn't play any games today and my screen brightness is low. For some reason Shadowgun stays in the battery info screen. I played the game two days ago and manually closed it out. Even after rebooting the phone its still there.
I'm being 100% real, stop trying to make excuses or act like I'm an iPhone fanboy. The Galaxy Nexus combined with ICS is the best phone I've ever used! I'm just terribly disappointed with the battery life.
Twittering all day is sucking up battery because of all the data use. Dude, youre not a light user with 3 hours screen time moderate, possibly heavy depending on background stuff sycing automatically. You have some tweaking to do, not whining.

I've tested out the battery difference by turning off auto sync. Doesn't make a difference at all. Fact of the matter is that the battery drains like crazy when the screen is on.

Except they aren't out yet
I will defer to the xda mods if they think this thread is redundant. I have been using my Galaxy Nexus now for ~3 weeks. During that time, I have seen my daily battery life improve from ~10 hours to a little over 24 hours before needing a charge. I have listed out the power saving strategies I've developed during these 3 weeks following the screenshot [PROOF]:
{

"lightbox_next": "Next",

}
1.) Calibrate your battery using the following methods here: Battery Calibration.
2.) While on battery power, set your Nexus display's brightness level to ~30%. I've found that particular brightness level to be a sweet spot. Auto brightness does not work for me, so I hard set the level. I am able to get between ~4 to 5 hours total of screen time a day on battery power at that level. There are many Android Market apps/widgets that will allow you to set power profiles depending on your location and power draw and/or charge.
3.) Along with conservative display settings, I turn off cellular data entirely, or only use 2G (Edge) when connected to a WiFi hotspot. I have an unlocked I9250 Worldband GSM Galaxy Nexus, so I'm unable to address 4G LTE. But if I did have access to 4G LTE, I imagine the only time I would use it would be for tethering while the phone is plugged into a power source. Regardless, 3G (HSPA+) can be a significant power draw, and 4G doubly so. When on WiFi, 3G and/or cellular data is off entirely. My guesstimate is this saves me between 15 - 20% battery power throughout the day.
4.) I set application accounts to sync and updates only when on WiFi.
5.) Avoid rebooting or powering off the phone while on battery power. I've noticed a loss of between ~2 - 5% when rebooting the phone on battery.
6.) No live wallpapers, and the image I do use for a wallpaper is very dark. I set the homescreen widgets to nearly transparent and white text. I'm certain this conserves battery power, but by how much I can't say. [REFER]:
7.) During a typical day for me, I'm constantly using Twitter, Google+, Facebook, Gmail, the ICS Browser, TapTalk, and of course the homescreen widgets connected to network services. I would consider myself an average to heavy user depending on the day. All Gmail is pushed. My widgets update between 1 - 3 hour intervals. You can tell by the screenshot provided my WiFi signal is always on, my Awake and Screen On times are between 4 to 5 hours total of the 24 hours available. As you can see from the screenshot, during that 24 hour period I did not top off with a power charge during that time.
Any other tips for extending battery life are welcome. I hope this helps.
Cool. I keep my phone plugged in when I am in the car or desk and that seems enough for me without having to compromise. 4G is a real killer
Are you using Tasker to kill data when on wifi and enable it when not?
I was under the impression the OS did this automatically

Err... if there is anything I take away from this thread, its: "If you want 24 hours of battery life on your Google Nexus, don't use it."
It's hard to say for certain, but it sure doesn't look like you used your phone very much over 24 hours. :|

Total time the screen was on was between 4 to 5 hours total out of that particular 24 hour period. Depends on your definition of "use", but I've seen definitions of moderate to heavy smartphone use defined in various forum posts throughout XDA somewhere between 3 to 6 hours of screen time on a single charge. YMMV.

Based on that image, there's no way you got even 3 hours of screen on time.

I'm certain it was over 4 hours, I remember digging into the screen stats under the battery settings before taking a screenshot. I don't have a screenshot of the screen stat window during that 24 hour period.
Don't believe me? I don't really care. I have nothing to hide and nothing to prove. Just relaying my experience with the GN battery over a 3 week period.
I would rather keep 4g on and just charge throughout the day. Why pay a premium if you're not going to use it, but I suppose you don't have 4g so you don't care.

This. Doesnt look like 4-5 hours screen time because the phone isnt awake enough.

I don't see a problem with the battery life for the size of the phone.
I'm sure it would go a day and a half before needing a charge with my usage (which I consider 'normal') but I plug it in everynight while I sleep anyway.
The battery life definately improves after a few charge cycles.
I agree with sc4, you basically are saying not to use the phone. You do not have to take such extreme measures just to get good battery life. I get pretty good battery life and I don't disable anything.
Well I thought it was a nice post. Jeez. Especially if you compare to most of the crap that comes up in the general section.
I couldn't find where he said "dont use 4g der". I believe the idea he presented was to turn off 3g/4g while you're on wifi. Do you need 4g AND wifi? Easy, common sense. Thumbs up.
Just so you know: WiFi uses the same amount of power to transmit/receive data as 3G. You're not saving anything by turning off the 3G radio while on WiFi since the only thing it's being used for is phone calls and text messages.
In addition, being in WiFi all day long can *really* improve your battery life. It's easily the biggest thing on your list. Why? Because the cell radio isn't constantly trying to maintain a data signal to the 3G towers. It maintains a connection but it doesn't have to negotiate for it almost at all...saves a lot of battery life.
Oh, and that Battery Calibration post is ridiculous. When you first get a phone just discard it fully then charge it up fully. Do it once every few months for the life of the phone and you'll find you maintain great battery life. Outside of that, keep it plugged in as *OFTEN* as you can to maintain longevity.
Also, according to your screenshot, your screen was on a *maximum* of 3 hours, but most likely around 2 1/2. That means the data connection most likely wasn't used much more than that, as well. That's very light use over a 24 hour period.

Well, no, you wouldn't...but it turns off the LTE radio when on WiFi anyway...so that's a moot point.
One more tip:
If you use vibrate on keyboard, shorten it to as low as possible.
This is possible using SwiftKey

Agreed that is not 4-5 hours of screen time. It is blatant in the graph u provided. Look at the screen and awake times. Here is mine with only 2 hours of screen time but over an hour of voice.

To push more, set the animation etc. to 0.5x in the developer options. This should reduce the cpu usage a little bit.
And turn off auto rotate as it consume quite a lot of cpu power. Most probably this is just a bug, there has been a report in the Google code bug yracking.

I agree. I did not get a screenshot of my screen time when I took the screen pic of the timeline graph. I was relying on memory, but after comparing republitarian's pic which has roughly the same timeline span, looks like my memory failed me. Mine is somewhere between 2 - 3 hours of screen time as well. My bad.

I am sure if I owned a smart phone it would have a reasonably good explanation. But i went to bed at some time during the night took the charger off while checking messages and woke up to a dead phone.
At first I didn't even think it was dead I have had one other day where I woke up with it off. It wouldn't turn on at all even after a battery pull thought it was bricked for some ungodly reason. Tried download mode which actually told me it was dead so I plugged it in to investigate.

Its not entirely abnormal after a few partial charges for some discrepancies in charge level. But thats a huge one if something was not severely draining the battery. Being half asleep I definitely messed up the screenshot.
There is a known issue with LED notifications causing a wake-lock on our phones. I see that you have a text message in your notification bar. Could the LED be the culprit here?

Could be it and I didn't have anything else installed to verify wakelock. But the stock battery stats doesn't show it being awake. The LED itself couldn't drain a decent battery in 2 hours but if the phone was wake locked hell yeah.
Of course I am on CM9 so there is a bit of an issue with the LED among other things.
Wow that's pretty shocking. I wouldn't think a led wakelock would cause it, but maybe a another background process being stuck. One thing i was never clear of is the network signal colors. I see alot of green, so is that supposed to be good reception? What about grey, light yellow, dark yellow?
Sent from my SPH-D710 using XDA
Even with no leds on i get slightly worse awake to screen on ratio. I highly doubt it has anything to do with wake locks. It must be something with the ics leaks cause once i lost 30% in just 30 minutes while my phone was on standby doing nothing. Wasnt awake according to stock battery stats either. I left school with 30% charge left when i usually should have ~50%. I flashed back to calkulins GB rom after that. And now i get 30 minutes more SCREEN ON time. and life is overall better even though i dont have juice defender on unlike when i was on AOKP.

That has to be a wake lock. I think for the most part people are getting decent idle drain now. Looking at the screenshot, it doesn't look like something such as email where you have repeated lines equal distances from each other. That almost looks like something you would see if Sprint was working on the network and it was down so the phone was searching the entire time but your signal is green almost entirely
Edit..are you using a Task Killer?

Was my other thought. Searching will murder a battery but is green not good? lol. I have never had signal drop off for a long period of time ever so no clue. But normally yeah the signal is all over the place in colors.
However this below was a day of me using my phone near continuously. Remote desktop into my server. Which is why the battery life was bad. Mostly solid on the signal which tells me solid green is normal for good signal?
Once again this is my raping my battery using it.

I put it on due to the missing task manager features from TW. The ICS swipe off method is annoying because it shows me apps that are no longer running. Can't tell me thats it though I mean 12 hour days of moderate usage with it and there is a problem in standby?

Green is great for signal. I am wondering if the task killer is somehow waking an app and causing it to run. That is seriously bad drain there. I didn't think it was possible to drain a battery in 2 hours no matter what you had running on your phone. The fact that you were asleep makes it even more strange

It wasnt. BBS only reported pandora and audio out as a significant wake lock which only drains 5% from my 10-15 minute drive.

Does no one notice I am not on Samsung firmware lmao. I mean reason for using a task killer since the TW task manager doesn't exist in this as i stated. That screen shot is no theme.
I guess I fail to see the point of this
I had a similar issue with this woke up one morning and phone was very hot. Turn it on and battery was almost dead, yet battery stats show's similar screen of what you have right there no awake time. My only theory is that on some occasions the phone goes into deep sleep with out throttling the cpu back down to 200mhz or what ever it normally sleeps at.
I'm thinking the cpu had to be pegged at max by a background task; you don't show any wake lock in your ss.
Perhaps it's a specific timing of turning on the screen, checking messages, unplugging, and turning off the screen left you with a cpu/gpu maxed out. Under normal usage, you'd use the phone some short time later, things get reset, and no one would be the wiser.

Hi guys my lg g4 is draining battery about 1% a minute when in use. Simple things like texting or web browsing cause this. This is a serious problem. My previous phones never did this. I dont know if this is hardware or software related. What can be the solution? Samung s6 has a smaller battery but outperforms the G4. My brothers iphone 6 plus has better battery life too. So i want to know what is wrong with the G4 which has the biggest battery out of the two.
Sent from my LG-H815 using Tapatalk
Same problem for me.. have to use spare battery and power bank when I'm not home. Drains super fast.
Also, you can't compare to iPhone as the software is super optimized and the hardware not the same (power friendly CPU and not the same amount of RAM). Plus they added some features to improve battery life.
I can tell, as my bro owns an iPhone 6 Plus too, the SOT is insane.
While doing same activities for 1 hour, my G4 is down at 75% and his iPhone is ~90%. On a day away, his phone lasted without problem while I struggled with my equipment to get 6 hours of SOT.
Meh.
Well the iphone aside but lets compare the galaxy s6 for instance. It has a more powerful cpu and smaller battery but still outlasts the g4. I don't know what is causing this. The operating systems are the same. Both running the latest os possible but getting different battery performance. I believe its a hardware problem more than software. What do you guys think? Can it be software problem?
Sent from my LG-H815 using Tapatalk
Something is wrong then gyus. I get almost 1h SOT from 100% to 90% web browsing.
Maybe is some rouge app or something else.
agree with chaki-, I'm currently ad 75% with 1h screen on time using HSDPA/4G connection. something is messing up your device.
you could try factory reset and monitor your battery life without installing any app to check whether it's a hardware battery problem or not.
Im running the latest os possible. I dont get how samsung s6 can have longer battery life compared to the g4. We have a bigger battery plus the s6 has a more hungry cpu. So how is that possible?
Sent from my LG-H815 using Tapatalk
I have found that Google photos does drain mine. I have to keep going into that app and change to backup on charge only. Otherwise it just keeps going and going. Battery drain with that is like 2% a minute
I understand you might have to disable certain apps etc but im talking about general use. Straight compare with the galaxy s6 our battery performance lacks. I dont see how that is possible. We should have much better battery life compared to most phones.

Neither do we so start posting your battery usage screens. preferably at the end of a battery cycle. no point posting at 80% or 50% left we want to see what it is at 10% or whatever low point at which you decide to recharge.
do you see any items above 'screen' in the battery usage list. if so, click them and screen shot them too.
You did not mention whether your usage is wifi or data, mixed ? what is the split.
Oh and is this a new device you just got. How many recharge cycles have you had so far.

Screen discharge on is 119% and when its off its 57% (!)
why ?
do you have many widgets that are updating. what about your wall paper. Is it custom, how big is its file size ?
This is just one thing that is killing your battery every time the screen is off and when it is on.
Try removing widgets and using a very minimalist wall paper, run it a couple of cycles and then tell us what your screen discharge figures are.

iphone has an auto-lock feature which allows it to sleep without being disturbed. There are equivalents in android but not built into the system.
it also allows to restrict apps from refreshing in the background. If you can do the same you will get the same result if not better.

Do an experiment, remove ALL widgets and use a simple wall paper. not live. file size of wallpaper must not bigger than 50kB.
Do two charge cycles. post your screen discharge on/off. also post your gsam.
I most of the time use 4G. However my point is a straight comparison to the S6. With both running the latest os possible and same usage style. So i dont understand how the s6 comes out on top with a more hungry cpu and smaller battery. What is wrong with our device? You would think we should have better battery life compared to the s6 or even the note 5. Its upsetting to see the phone lack in battery performance

This will kill a battery quickly if the signal isn't good. Relying on signal bars isn't enough
The way to tell how good your 4G signal is to go to settings->general->about device->status-> look for signal strength
there will be a figure there in dBm. How much is it ?
Its not a signal problem. I have already isolated that from the start. My comparison was with the s6. How can it last longer when we have a less hungry device with bigger battery

Because something is draining your battery faster than on the other device. As to what that 'something' or 'something's remains to be determined.
state your sot and total run time.
Btw how long have you had this device ? how many times have you charged it.
2 months i had it for.

I can see lg g4 is not power efficient like the s6. So we can never get the same battery life as the s6. Even though we have a bigger battery. This is really unfair.

what is your avg sot/run time. when on wifi and when on data. second time i've asked this basic question.
in two months what have you tried to do to improve battery life.
I tried to minimise brightness to about 30%. Deleted all the extra apps. Updated to the latest os. Updated all the apps on the phone to latest available. So something is wrong with the G4 in general. From what i read on the tests professionals have done is that the G4 isn't efficient like the s6. So this must be totally a software related problem. Os is not optimized to be efficient. This device has let me down in regards to battery life. I would most likely want to go with another device probably the xperia z5 premium. However i dont know how the g4 would perform with the marshmallow update. That is something we have to wait and see. Hopefully LG do a better job at it this time.
