Impressive battery life

I have been very impressed with the battery life I've been getting on my Nexus. the talk time has been much higher than any phone I've owned. Here are a few screenshots of my battery life. These two days are pretty much my normal day (lol yeah I talk a lot on the phone).
The first post will be the day that about 50% of the time I was on wifi.
The 2nd post will be screenshots from a day of being connected to hsdpa for the entire day (no wifi at all).
My setup: I use push email, facebook sync, auto brightness, gps on, bluetooth on.
Also, when the phone first came I charged it completely then ran the battery down until the phone shut off. I then charged it completely without removing it from the charger.
Below is the day where I was connected to wifi about half the time:

These screenshots show the next day where I used no wifi at all and was connected to hsdpa the entire time.

I have had mine for 2 days, and I have to say it seems to have pretty good life as well, compared to my Atrix and Note. After reading about all the gripes here,
I was expecting the worst. This battery will more than get me through everything I need to do with it in my day, but I suppose it all depends on what you do with the phone.

Coming from a G2x with a terrible 10 hour battery life, anything I get out of this is freaking fantastic compared to it! I Just wish the devs start getting out some UVed kernels so I can make it longer through the day! I consider myself a heavy user/texter (girlfriend ) and so I'd like to get through the whole day (~18 hours) without a charge I must say, I got to 16 hours yesterday and I was really pleased with that, never had a stock rom last so long without any tweeks!

this is my battery life after first day ....
Not to shabby haha

mysterioustko: I think you're usage is a bit different to the average user. With all that talk time you're using the screen a lot less. It seems the screen sucks a lot of power, and if you're not using it often a full charge lasts 4 to 6 hours longer.

I typically average between 1-2 hours of screen time on an average day. But I talk A LOT each day lol. I'm impressed with the talk time because I've yet to see a phone besides this one that can go 6 hours of talk time in the real world when connected to hsdpa. Also, if you think about it, 1.5 hours of screen time is decent use. It's not a massive amount of use, but it's definitely not like it's getting no use. All in all I have been pleased with the battery life.

I don't know about you guys but im very disappointed in the battery life. With wifi turned on the entire day and no calls, just browsing and chatting on google talk, i got 3 hours 54 mins of screen on time before the phone reached 12% battery. I think thstss pretty horrendous. I was hoping for 7 hours or something of on screen time. My galaxy tab 10.1 has spoiled me i guess. Illl live with it because theres no other android phone im aware of that will give me more, but im kinda bummed about it.

My iPhone 4 has insane battery life... I cant imagine having less. Hopefully they sell larger batteries + backplates for the Galaxy Nexus?

Same here tbh. And the really frustrating part is, I only have 2G where I live so I was hoping to see really great battery life. Hasn't been the case so far though.
However having said that, just last night I flashed XXIK6 and while it's still very early to say for sure, it "appears" that battery life has significantly improved for me. Currently sitting on 91% after 3.5 hours with very, very light usage, IE: 15-20 mins screen on, 15 min phone calls, etc. Nothing to write home about sure, but way way better than before. It would normally be around 80% by now.
It's really sad when the very first thing you do after unlocking your phone is to go into setting to check your battery. Wish I could stop obsessing and enjoy this marvelous device without having to worry about it.

What did you guys do after getting the phone.
Did you charge it all the way to full before use, use and charge at the same time, or let it discharge all the way and then charge it to full?
Thanks.

I would have to say that the GN has the best battery life of any of my previous android phones. (G1, N1, Sensation) These things are very subjective though.

Yeah, and I don't want to lose the thinness of this gorgeous phone with an extended battery, but 4 hours of screen on time? Anyways, can you let us know how that radio works out, I'm not expecting much, but still curious. If it is noticeably better, I will try to unlock+root this phone. I'm just a little scared to brick this 700$ device.

I'm just waiting for mod of web browser that will invert colours. Black backgrounds and white text ...that would extend battery life significantly. I swapped colours on xda app and pulse reader only browser left ha ha

The inverted colours app is already there isn't it? I saw it when I was fiddling about with the browser settings before

I think the battery life is spot on. Last phone, Nokia 5800 would last 8-10 hours max on stand by!!!!

Yup, it's under accessibility in browser settings. Great if you read mainly text-only sites since it inverts image colours as well

2-3% per hour idle
I did a benchmark this afternoon for about 8 hours.
ITL41F rom, rooted + dcm kernel, otherwise stock. bluetooth, HSDPA, 1 gmail sync, and a few background sync that is very light.
idle the phone in home for 8 hours. the battery drops about 2-2.5% per hour consistently.

how long does it last with 'constant use' though?... from fully charged, to then having the screen on the whole time & doing web browsing, video watching, downloading, etc... (with data on, not wifi)

with data screen straight you may get 4-5hours. With wifi probably 6 tops.

Ughh battery drain definitely too fast.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.

Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?

Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.

Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

Wow, really? At first glance in all sub-forums I saw about two, if that. I have a legitimate concern, especially when my friend is getting about 4 times better life. Thanks for your help though in the device forum where this 'doesn't belong'.
..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.

I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel

From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.

Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise

[Q] Need a help on a new phone.

Hi Guys!
I'm currently looking for a new phone. I can only buy midrange phones atm and since the G4 and S6 are released, I expect both of their predecessor's price will go lower. Apparently, I'm torn between the previous flagships, G3 and S5, which is still of course still capable now. I really like the G3 over the s5 but I am bothered by the battery life that most people say is bad. I mostly need the phone to school at around 12 hrs off the charger. At school I usually just text and call a few times, take pictures and notes, occasional time wasting games on breaks and also I listen to music on trips to and from school [approx 1.5 hrs of music]. My question is, will the G3's battery be capable of that amount of usage? Or will I benefit on the S5 on this? Thanks in Advance!

That's very similar to my daily usage pattern and my G3 never died on me. You can expect between 4-5h of screen on time. It really depends on your signal, if you live in a poor signal area, any phone will take a hit in battery life.
The majority of people who complain about G3's battery life came from a G2 or similar phones, and they're used to getting 6+ h of screen on time. For them, it was a downgrade in the battery department.

Now I'm starting to get really excited to get this phone more, well, another question, are there any major gripes on this phone? Also coming from an old phone with a really mediocre battery life (Xperia Sola), I think the battery life of this is definitely enough. Based on what I read before, It's mostly the battery, but as you said, based on my usage, I would get throughout the day easily, so the batteries are crossed out. Any other major thing (flaw?) you would say?

It's all relevant, some things that annoy some people might not be an issue for others, and vice versa.
For me, there are 2 things i don't like about the G3, but they are not that big of a deal, i can live with them. The first is i would've liked if the display can get a bit brighter (especially on very sunny days). The second, coming from the last 4 generations of nexus devices, i miss the software fluidity of stock android, despite that i appreciate some of the feature additions LG has thrown in their "skin".
All in all, i would take the G3 over the Galaxy S5 anytime.

Ok, I went to a local LG store in my place and played on the LG G3 a bit. The G4 was there, and I'm drooling over it, the leather back was so nice. Ok ok back to my question. After using it for a few minutes, I noticed the brightness to be low and I checked it, it was at 90%. My problem is as I am trying to increase it, there's a warning shown that the temp was high so I can't increase it more. My question is, does it happen often? The overheating?

As an LG G 3 power user I can confirm that the phone will indeed heat up from time to time, however, the phone you played with was most likely plugged in to a charger from what I can read.
Any phone that's being charged up and used at the same time will get hot, it simply puts more strain on the battery.
You should be able to get the 12 hours you need out of your device on a full charge, especially with the power save g to that come with it, however don't expect do go a full day (24hrs) without it having to hit the cradle.
I hope this helps.

Indeed it was plugged. So I guess it is indeed because of that. It's ok for me if I need to charge it everyday, as long as it can last for 12 hrs. Thanks!

You can expect much much much better battery life with G3 or S5 than your soon-to-be-ex-phone Xperia Sola.
Both G3 and S5 almost the same battery life, even though G3 is better in standby time.
If you buy G3, immediately update it to latest version. Your phone will not overheat ever, like mine never did
Only hard gaming for a 1hr+ time can make it overheat.

Well...Depends. I don't think it'll last for 12 hours. You get 5hours of SOT only on the lowest brightness setting, higher the brightness lower the SOT. For me in school it lasts for 8 hours max, then gotta charge it. Also it's true I'm using it most of the time for 4G so that may be why.

I really think it's battery life would be enough, as what you all said, also since I can manage to use my sola for that amount of time which has a ridiculously short battery life. Hahaha! XD. Also thanks for the info! I'll definitely update it, to get a taste of the lollipop's sweetness.

I only use 3g (H+ is enough for me), so definitely/ probably I can get it pass that 12 hr mark. Signal was a bit of a problem though at school, since the school is near a jail, they seem to have network jammers installed. Weird.

Battery life so far on the G4 is horrible

Is the G4 really this bad? I bought one a few days ago, coming from the G2. I'm waiting for it to settle in but damn.. this thing goes through 3000mah like a fat kid through candy. My G2, now 2 years old lasts twice as long SOT. 6 hours to 3. I just.. I want to love the 4, but it is just too power hungry. Does this beast settle down over time? I have a week more to return it for something else, and on the verge.

Since firmware v10c there's a problem with GPS sucking battery. Try setting it to “battery saving“. Perhaps this improves things...

Yeah. Read that. Shouldn't have to turn everything down or off in 2015. I so love this phone but wow. The battery is nonsense. I went to it because my G2 was/is a champ. What is going on with this thing?

The battery in the g2 is much better, but finding a flagship from 2015 with a better battery than the g4 (and a comparable camera, screen, size etc.) is impossible.
It charges more than one percent per minute with6a normal charger, and you can buy a spare battery and a fast charger but the sot isn't going to get much better than what you're expering now. It's still the best phone ever imho.

I got a free battery with it, and the charging cradle. Which is nice. I guess I just got spoiled. The G2 is so awesome, and I expected this to be the same. It's not. Not even close. I bought this G4, a Note 5 and an S6 at the same time. Both Sammy's perform much better, and that pains me to say. Ugg.

You could help if you complain to LG about the GPS battery drain problem like me and others did already. Try “battery saving“ on GPS and post your results afterwards. With a decent screen brightness, I always get 4+ hours Screen on time. Not playing games or doing heavy battery draining tasks, though.

Man oh man, you are having better luck than I am. I might have a faulty unit, not sure, but the battery on this one is like driving an old car with a big V8. When you stomp on the gas you can literally see the gas gauge go down before your eyes. This phone is no different. My G2 was honestly 3X better than the G4. Good luck to you guys, and I mean that sincerely, I do. But I'm returning this thing. For me, at least... it is a pass.

Kind of the point though. I shouldn't have to tweak settings, and root a brand new phone to make it work. I'm not here to bash the G4 (I own it) but it stinks.. Ok.. bashed it lol. Seriously. I have the exact same apps loaded on it as my G2 and if sucks battery like a $2 hooker. The Camera is good, not sure as great as was reported. The speaker was kind of bashed from the reviews but I think it is AWESOME! So loud. But... battery. Nope. I don't care if they give me 40 free ones to swap, I shouldn't have to.

No...my g2 got 5.5-6 hours screen on with medium use...i have gotten 5.5 to 6.5 on my g4...not defective but actually quite effective...my g3 battery was garbage...g2/g4 are masterpiece

That's kind of what I meant. With my debloated, greenified, taskered, tweaked and optimized g2 I got sot of up to 10 hours, the g4 gives me 4-5. Except from every test ever and every user experience, I think not even LG tries to pretend that the g4 has the slightest chance to reach sot like the g2 did. You're the first person to say so ever, so I assumed the only explanation could be that your sot on the g2 were mediocre.

If you got 10 hours sot with g2 you were heavily underclocked and at that rate wtf is the point...i actually got a much smoother experience and better battery life by raising the min clock on big and little cores as with the stock settings both jumped around ridiculously chewing up battery on simple processes...we shouldn't have to root to fix anything but it's never the case...and getting 21 hours out of my g4 with 6 hours sot with browsing some gaming and lots of youtube vids I'm beyond impressed...h811 has no custom kernel yet so no undervolt is present...this phone will just continue to get better imo...i cant believe the complaints i see about a device that surpasses 95% of anything on the market

Is the G4 really this bad? I bought one a few days ago, coming from the G2. I'm waiting for it to settle in but damn.. this thing goes through 3000mah like a fat kid through candy. My G2, now 2 years old lasts twice as long SOT. 6 hours to 3. I just.. I want to love the 4, but it is just too power hungry. Does this beast settle down over time? I have a week more to return it for something else, and on the verge.

If you don't use auto, what manual settings for brightness would you normally use on the G4 ? Mention the figure in % or the range.
Are you on wifi or data, mixed ? what share each.
i gather you are on H815.

hey there @android404 mind sharing your g2 setup for those 10 hours and screen brightness also? i'm thinking my g2 might be a lemon i never reach even 6 hours with no heavy usage but i am on stock rom and kernel and i don't even use greenify i have no problem rooting it so please can you tell me your rom kernel clocks and whatnot? thx in advance.

Update. I went for broke and did a factory reset before I was forced to return it. Seems to have made a world of difference. Now it is performing the way I would expect it too. Not as good as the G2, but not draining before my eyes. I think something must have been borked. I'm going to be cautiously optimistic atp, but I have a week more of daily use to play with it. (Might get an extension) but so far, in the last 26 hours it is night and day difference. Whew. Really didn't want to take it back.

Normally keep it at 60% and mix between wifi and data but 75% of time it is on wifi. H812.

Yeah. Much better. Been unplugged for 10.5 hours and sot is just over an hour. 84% battery left. Same usage before the reset and it would have already been next to dead. Something was mucked up. I take back what I said before. This is what I expected.

Glad to hear it...i hate to see people leave for bad experience on a device that has such potential...development is slow atm but once cm gets stabilty and a few more variants have unlock/workaround this device will gain notoriety like the g2 had and the g2 was a beast...was my favorite device to date and i see the same potential here

LG G4 - Pitiful battery life

Hello all,
I recently purchased a LG G4 Back In July , on Verizon, switching over from A Galaxy Note 3 (Tmobile). Honestly I really really like the phone, but I think the battery life is pitiful for a $700 dollar "Flagship" phone. I mean not once has it ever lasted the full day. I had to buy a spare battery kit, with 2 batteries, and days when im out from 6am to late at night, I go through 2 batteries, and have to put the 3rd one in. I mean , this is simply unacceptable for a phone like this.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.
I am hoping there is a way to fix these 2 issues, mainly the battery issue though because it is awful in my opinion. Is there any tweaks or fixes for these issues?

You've barely given any relevant information other than how unhappy you are with the device, so I would suggest that you elaborate on that.

You could inform us if you're a heavy/light user, if you keep NFC, LTE, Bluetooth, Syncing, Wi-Fi, on during the whole day or maybe if you are used to 100% brightness display. Maybe you should check in your settings what is draining your battery and provide us the info.
I'm having a pretty good experience with the phone so far. It surely lasts a whole day with 3:30 to 4h SoT. I don't even need/have a spare battery.

One person having an issue doesn't mean it's not a great camera. You'll find it's likely still the best flagship camera of any OEM.
Battery use is so dependent on which apps you run, which mods you have, how often the screen is on, what brightness, signal strength, wifi, bluetooth, etc etc etc...

I came from a galaxy s3 and reckon the battery on g4 is awesome. I use it solidly on internet for 2 hrs a day (to and from work), check messages etc through the day, usually internet at lunch. And then evening time check facebook etc over WiFi infront of telly.
I unplug at 6am and plug in around 11pm with around 3% left. I bought a 2nd battery and only needed to use it twice. It has to be how you're using it.

13 hours on battery for me today and still 71% left. Light usage but it does illustrate that the battery life can be excellent.

of course, you can get excellent battery life on every smartphone - just put it in aeroplane mode..
I get MAX 3h of SOT time on my G4 - this is with fixed brightness at 65% (at all times) and only wifi and 3g enabled (NFC, bluetooth and everything else is turned off all the time)
to be fair I have yet to own a smartphone that lasts me more than 4h SOT..
the thing that annoys me the most is the broken knock code used to unlock the phone - it works 20% of the time at best
its a completely broken feature LG has not properly addressed since launch of the device (I am on V10e software)

There have been numerous firmware updates since. Have you ever performed a full factory reset after getting those updates ?
If the answer is no, then this is one potential reason for poor battery life. What you could try is to clear the system cache in recovery. Note, i said system cache not apps cache. Idea here is when updates come in there could be conflicts and it causes the system to work harder. clearing system cache might help, if it does not then the only option is a factory reset and then a manual install.
not restore. You install apps in batches, monitor, then install more and so on. You can restore contacts etc. but apps themselves will have to be reinstalled. Sometimes apps go rogue and have to be reinstalled. Its hard to tell which app is causing the issue. Otherwise you could just reinstall whatever app that seems to be taking up more than it should be.

What are you doing on your phone ? mention apps.
How do you access the net. How good is your signal. What are you doing when you access the net.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.

What types of shots are these. It can happen with portraits some times. It will focus on the background behind the person instead of the person and the face becomes softer and the background very sharp.
For this set focus little above the chest instead of the face. If they are wearing dark clothing this will cause other issues so focus on something else at equal distance that isn't dark.
Always check the shot at the pixel level soon after you took it. Rather than at the end of the day.

Just to clarify: I had everything turned on for those 13 hours - wifi/data/bluetooth/GPS. I also made 2 phone calls and did a bit of Chromecasting using the BT Sport app for a couple of hours. Or to put it another way, I didn't take any measures at all to preserve battery life.

I used to complain just like you're doing OP ( @dredmentia ) and fixed it all with a Zerolemon battery .
Is the phone bulky/no leather back/not easy to handle... , it sure is but if battery life is crucial then it gotta get fixed.
End my day anywhere between 7 to 13 hours of sot depending on WiFi or 4g and high CPU freqs, tried light usage and hit 3 days with 12 hours sot. Snap/insta/twit/fb/periscope/... Nothing kills this battery in a day.
When and if we get a kernel I'll move back to factory battery at least then I know I'm in control of how CPU works coz while optimizing the phone for wakelocks that's the only thing I have no control over...
As for now I'm just trying to burn thru this battery every day so I can charge it every night...
Last phone was a Z3 Sony and that really grabbed my attention with its battery life in stock form, almost too perfect, Almost.

This is what your talking about? Looks like a pretty nice battery.
LG G4 Battery Case, ZeroLemon LG G4 8500mAh TriCell Extended Battery + Soft TPU Full Edge Protection Case (Compatible with all LG G4 variants) (4897010519648)
It works with the USB charger that came with the phone ?

Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

Then maybe something is wrong with the phone. I got also 4-5hr SoT.
It can't be just 2hr.
