The G4 is proof that one does NOT need to disable useful android features to get acceptable battery life.

When I had the S6 people would tell me to disable all location services, location history, google now, twitter sync and uninstall facebook and do a bunch of other crazy things - which basically nullified its android advantages - to get acceptable battery life. I did exactly that and the battery was still awful.

Enter the G4 with everything of the above active plus 2 additional exchange accounts on sync - all on 4G - and I only lose around 8% battery in 7 hours overnight. With the S6 and everything OFF I'd lose around 15-20%, sometimes more. THIS is how it should be, I shouldn't have to disable anything to get acceptable battery when I'm not even using the phone.

Granted the battery isn't exactly stellar when the phone is pushed and the screen is constantly on, but the amazing stand-by means it's really good for MY use - I can easily last 24 hours with 3 hours SoT, with the phone without any battery anxiety.

UPDATE: New G4's battery life

So, hours ago I mentioned that I exchanged my previous G4. I brought ir home and switched it off & charged from 35 to 100% & then actually started using. I have been using G4 so far for downloading a few apps, receiving a few calls, background sync is on, brightness at 50%, browsing internet & this is (below) what I got : SOT 1 hour 45 mins at 60% remaining. I must say I am bit happy now. I think my old one had really some issues.
[G4 General] Striball:
8% overnight isn't anything to be proud of, it's still not great. The S6 has a memory leak or something along those lines that I read.

Overnight I'd consider a 1-2% very good. I haven't tested my G4 yet but I know that the G2 would stay at 100% over the course of 8ish hours. I'll test the G4 tonight though.
[G4 General] nismo929:
I just left mine off the charger for the night (6 hours), with Wi-Fi and sync turned off and only lost about 1 %.

I recently turned off fast dormancy and noticed a big improvement in Sot, about 1 hour more, bringing it to around 5 + hours. Tonight will be charge cycle number 5. I did disable locations as I don't need gps very often.

I am using greenify, and attached a photo of the apps I've disabled. I live in the middle of a big city with good phone coverage, but know if I was visiting family out in the country side..might not be as good. I'm really wondering if people with bad battery results are maybe linked to one network? I'm also assuming that you have a lot more bloat ware added than the unlocked international version.

I am very happy with this phone so far. I am sure that I will be topping out soon for screen on time, but hopefully shortly after, custom kernels will come out to improve it even more.

[G4 General] Kenishi99:
While I had pretty bad battery life at the beginning when I first bought the phone it's now pretty good.

5 hours SOT - that's not bad at all!

See screenshots. :)

I never reached more than 2 hours SOT with my Sony Xperia Z I had earlier or with the Samsung Galaxy S4.
[G4 General] Lock-N-Load:
I just used 10% in 30 minutes on the web with brightness 1st a mere 20%. Nothing special running in the background.

That seems pretty poor to me.
[G4 General] nismo929:
What charge cycle are you at?

Sent from my LG-H815
[G4 General] nipun1110:
LATEST UPDATE: After my last post at 60% battery left, I changed the brightness to 25% as it is night here. So high brightness isn't needed plus I wanted to do an uniform test. Well here I am. 25% left with SOT about 3 hrs 12 mins. I am happy coz I think it will improve more later on.
[G4 General] Lock-N-Load:
Maybe 3-4 and none from 0% all from about 40-50% on the low end.

And last night, overnight, it used like 7-8%... which also seems like a lot.
[G4 General] nismo929:
Perhaps try out GSam battery monitor (paid app), or something like this to determine what is eating power at night. What variant are you using?

Just for a recommendation, turn off sync mobile data and Wi-Fi. Limit the things you have on to almost nothing...and night by night, turn one more on to see if you can find the power hungry culprit.

Also maybe run it down to at least 10% once or twice....no harm in it.

Good luck!
[G4 General] EVOme:
Coming from the s6 edge, this battery is 100s better. check this out...
[G4 General] nismo929:
Charged this morning, out and around half the day wanting the city, mobile data on for a few good hours(4~5 hours), screen at 50 most of the time, blue tooth streaming to headset, a little gaming.. LOTS of camera time.

I've had longer, but playing so much with the camera did it in.

Still Happy with the results.

[G4 General] Cor-master:
Mine honestly seems fine and a huge improvement over what I'm used to. Trying to not take a lot of stock in the crazy SOT time like 8-10 hour's because I'm not going to disable all the services just to get it. Still I got 4 hours yesterday and had 24% left when I put it on the charger. That's pretty impressive considering my nexus 5 I only ever could get 2½ hours a charge.
[G4 General] Lock-N-Load:
I should have explained that I run nothing unless I'm using it: Wi-Fi, bt, GPS, nfc, etc. And I use tasker to make profiles like:

Turn off bt at 9pm if accidentally left on

Turn off Wi-Fi at 11pm if left onon

At 11:30pm put into airplane mode until 5:30am

And so on

Mine isn't too great. The phones been off the charger for about 11 hours and it's at 10% with maybe 3 hours of screen on time.
[G4 General] AhsanU:
Got better battery by disabling a lot of the Google apps I don't use that I didn't care for before (thanks to Greenify). Two and a half hours of screen on time with 50% left isn't bad. Mostly texting, some camera stuff, and chrome browsing. Location turned on with Bluetooth on (I have a Moto 360). Not bad, but it'll definitely get better once we get root

[G4 General] nismo929:
Well then something is not working as it should. I passed out on the couch last night, unplugged my fully charged phone in the middle of the night while going to bed(3am). Still at 100 % in the morning and even got twenty mins at about 35~40 brightness before dropping down to 99%. You should be doing even better with with airplane mode on.

Another app to try monitoring is power tutor, not sure if it is lollipop compatible. Can you fully charge night before and give us a pic of the battery consumption menu?
[G4 General] Semantics:
Satisfied
[G4 General] Pyrres:
This is what happens when you manually toggle fast dormacy on at lunch. Not big but notable difference in idle consumption.

[G4 General] nadram:
So far, after 5h45m I still have 43%

Bluetooth on for 5h, most of which I've been listening to podcasts and music, 4 phone calls, a LOT of tweaking my setup (I only got the phone yesterday night), installed a couple of apps and uninstalled some others, downloaded some files, email checking, 2 active sim cards, Wi-Fi on, location on.

By now my N5 would have been 100% out of juice.

I am impressed. And happy.
[G4 General] Derpling:
My battery drain is insane, but that not caused by screen but by facebook, google, google+ and chrome.... other than that super satisfied.

BTW what is fast dormacy? how u enable it?
[G4 General] nismo929:
Check the thread...answered already.

277634#*#

Check if your mobile provider supports it. If not...better to try with it off.
[G4 General] jmp485:
If you're on a provider that uses some variation of LTE-Advanced go to the network settings and disable that. On AT&T it was called "Enhanced 4G LTE". Night and day difference in battery life for me
[G4 General] Sher The Love:
I ended up doing that Saturday night and "phone" was nowhere to be found in my battery stats yesterday. Worked like a charm.
[G4 General] didi_ghost:
You did that on the HIdden Menu ? Field Test > Modem Settings > LTE-A CA setting > CA Disable ... ?
[G4 General] Sher The Love:
No, just through regular settings. Settings>networks>more>mobile networks.
[G4 General] rfarrah:
I have Advanced Phone checked and "Phone" is way way down the usage list. Google services is the one eating my battery the most.
[G4 General] pfizzle:
Do you by any chance have trusted places enabled in your lock settings? I had mine enabled for the last few days and Android system and play services was always right near the screen in battery usage. Plus I would have a constant location lock notification randomly.

I've just turned it off and in the last hour I haven't seen either of those battery uses. I'll see how the rest of the day goes, but maybe you give that a shot if it's killing your battery too much!

I wish we had root because I used an xsposed module called No Lock Home which was amazing. Allowed me to disable my lock screen when connected to my trusted wifi connections, and then automatically enabled the lock screen when disconnected. I feel like this is a lot more battery friendly than the location method which needs GPS constantly
[G4 General] rfarrah:
Just checked to be sure, and I'm NOT using Trusted Places or any of those settings. Thanks for the suggestion, but I guess I'm still looking for an answer / modifications / fix for Google Services.
[G4 General] maddog497:
Seeing as you in Canada, which model did you buy?

Thanks
[G4 General] Sfkn2:
Hmm that's interesting.. Google Play Services is at the top.
[G4 General] nismo929:
Actually living in Germany..so the international unlocked H 815...if I was back home...I'd still be waiting:beer:
[G4 General] AhsanU:
I suspect it's on top because of mightytext, which uses Google services to let me text from my tablet/laptop/computer. Not sure if that's normal, but I think my battery life will definitely improve since I've enabled fast dormancy mode as well.

Seriously, this device will kick major ass once we get root.
[G4 General] Sfkn2:
My Google Play Services is only at the top when I'm 100% on LTE. I'm not sure why, but it's never at the top when I'm on WIFI. Still lots of research to do on my end.
[G4 General] maddog497:
I don't have one yet but have been following this thread for when I get it.

I don't need 6 hours of screen on time but there's just something about being able to get it and also have a great phone, great camera and the ability to get accessories easily.

I ready liked the G2. It was a real sleeper. Most didn't jump on the bandwagon until it had been out for months. The G3 was not an upgrade in many ways.

I have either lucked out or am doing something right, experiencing very good battery life even though I spent a lot of time today messing around with my home screen.

Running non rooted, non unlocked. Location on high accuracy for Smart Lock. Screen on 50% auto.

Just a quick question, I am running Greenify in non-root mode at the moment... is it possible to change the power button to perform the shortcut "Hibernate + Lock Screen" instead of just lock?
[G4 General] stl-soldier:
I don't know of a way to map the power button to a shortcut, but I set Double-tap Home Screen to Greenify Hibernate + Lock Screen in Apex Launcher, which works great.
[G4 General] nismo929:
I am very satisfied with the battery, but I do use Wi-Fi most of the day as it's available which really helps. 6 hours I think would be close to the realistic maximum average of the G4 with screen at mid to low brightness (with all the high energy consuming games and apps..likely less also for you Facebook zombies :rolleyes: probably closer to 3~4)

I did go on some bike rides to find somethings to photograph, and while playing with manual mode, it did take a dip. I did have full brightness on as well because it was around sunset.

But this morning...Got over an hour before 90 %.

What many people don't realize is that some apps are battery KILLERS. If you like games so much...get a cheap tv and a ps4...almost the same price.

[G4 General] mediumraresteak:
I think the auto brightness option is what gives people longer SOT. I tried manually setting the brightness to 50% (no auto) and after 1 hr of gaming, I was at 45%. I'm not sure if that's good but with auto brightness, I could push 2 hrs. Basically without auto brightness, I had 4 hrs of SOT but with auto brightness, I had close to 6 hrs.
[G4 General] vlug:
My phone isn't even lasting for 5 hrs. I already returned one because it was dying too quickly. Also it heated up so much while charging, it stopped at 70%. I have a new one now. Both devices drain extremely quick with screen on. Display always between 30-50. One gmail account with only email, contacts, music, and chrome to sync. No location anything. Some of the bloat disabled. As of right now I have a SOT of 30 mins. 6 hrs of battery left. 9% used since I took it off the charge. with 90% battery life left. All of this while I only had the phone off the charger for 40 mins. I have the sprint variant. I see other have 13 hrs of usage. Almost 2 days of battery left. My two phones I had already would've never made that happen. I plan on getting a s6 edge.
[G4 General] rfarrah:
My problem is that I like this screen nice and bright. I have it set at 89% - no auto. I'm sure that doesn't help my battery life.
[G4 General] LancerV:
It seems like non carrier variants are getting the best battery life
[G4 General] vlug:
That's what I am thinking. It sucks
[G4 General] LancerV:
Yeah hopefully when root and unlocked bootloaders come out fix most of the issues
[G4 General] Sfkn2:
You guys have to keep in mind that LTE and 2k displays drawing power for YouTube and whatever you're watching is going to drain the battery.
[G4 General] vlug:
Yea this is true. But, I use WiFi mostly in home without watching any videos. I still witness the same type of drain. I'm certain this is just a variant thing. Sprint mainly.

---------- Post added at 04:38 PM ---------- Previous post was at 04:35 PM ----------

I guess this is why they are giving out free batteries
[G4 General] Sfkn2:
Can you post your battery stats for further analysis?
[G4 General] rsbenedict:
I have heard that if the bootloader is opened up that we'll lose all of the extra features of the camera. Android Central said most of it is proprietary and not owned by LG, so when they open up the bootloader, they will have to still hide the proprietary stuff with the camera. Not sure if this is true, but this is what Android Central was saying in the LG G4 podcast a month ago.
[G4 General] vlug:
(Screen shots from earlier. Some time before my post.)
[G4 General] Sfkn2:
Posting it at the top of a fresh battery doesn't help.. Try again at 10% battery life or so.
[G4 General] vlug:
Well its gonna be there in four hours so I'll post it then. How does it not help though?
[G4 General] Sfkn2:
You're not using your phone the same for the next x amt of hours, right? Looks like you're on the phone now. Are you planning to be talking on the phone constantly?

Usually when people talk on the phone, their screens typically aren't on... seems like you're on the phone while taking screen shots..
[G4 General] vlug:
Yes I know what you mean. The thing is though, From the fresh charge it was draining. As you can see. I got on the phone then noticed the fluctuation. Yes I know, from the screen not being on. I took the phone off the charge maybe 4:10 pm. (Chicago). it's now 6:59pm. Here's my current stats of what I have been doing. I just feel like I didn't do anything and I shouldn't have to put my phone back on the charger to make it last for my graveyard shift. 9p-2a. Which then screen will be off with music playing and Bluetooth lg headset in use.

Edit: SOT was 1 hr 30. Phone time was 58 mins.
[G4 General] *justintime*:
Don't believe the chit chat on Android Central.....

Mine is unlocked and camera is still performing.

Hi,

This is my 6th charge and battery time is getting better by every new charge. I got SOT around 3-4 hours but the strange thing that Cell standby is eating around 50% of battery..

Can't figure why.. Any idea??
[G4 General] bahamot_zero:
The longest so far is 26 hours and 40 minutes with 4 hours SoT
[G4 General] nadram:
I managed 13 hours yesterday with slightly more than 10% life remaining.

GPS, Wi-Fi always on, Bluetooth on for 8.5 hours, at least 100 emails received on 4 different accounts, some 4-5 phone calls, listening to an audiobook and podcasts...

This was my 2nd full day with the phone. I'm damn happy at the battery performance
[G4 General] didi_ghost:
It's not using your battery, it's just informing you the total time the phone spent without being used (sleep time).

First day with thus phone. I had total of 4h 32m SOT at 3% last night before it finally died. I wasn't on wifi all day yesterday either (while at work) even though I was using my phone quite a bit.

I'm loving it.
[G4 General] kafreeman:
First full day of usage yesterday.

Cant complain, dont think i ever got to 4 hours on the G3.

My wife was at 4 hours with 26% remaining though....
[G4 General] AsianTex:
Isn't that Phone Idle? I only see Cell Standby when the phone is constantly looking for signal. Really apparent when I'm in a place with poor cell reception.
[G4 General] WhiteHartMart:
My battery life is reasonable during the day - a bit better than the S6 I had but 4 hours SOT would be the most I'll get with my usage - I'm usually charging at about 10% with about 3.5 hours SOT.

One thing I noticed was my phone doesn't seem to idle as well as the review state - BBS reports deep sleep but over a 6 hour sleep I'm still losing 12%+ battery?
[G4 General] Pyrres:
Now my batterylife is fine when idle but screen on with 50% brightness kills the battery. I cant get much past 3h40min SOT and with my M8 my average was almost 6hours SOT. I knew it would be worse but somehow expected worse idle and better SOT.
[G4 General] AhsanU:
Welp, it turns out voice calls really kill the battery - I picked a bad time to start dating someone that enjoys the traditional phone call haha.

But my phone just gets demolished by phone calls. I started a call with the lady friend around 10:15 pm and ended it around 12 am, I lost about 30% battery life in that span with absolutely no screen on time. I was connected to WiFi.
[G4 General] aaronc_98:
With everything on I am only getting 8-9 hours with 1.5 SOT, but this is the first full charge. I have greenified a few apps, but that is it
[G4 General] randpost:
4hr SOT with 10% remaining. 18 hr total. Disabled wifi search, and wifi calling. Location and GPS were left on plus I have G watch connected at all times with full permisisions. Not bad at all.
[G4 General] ingoljosh:
Battery life is already expected to be worse than the G3 out the box.

Maybe with some tweaking we can get more juice out of this beast.
[G4 General] Ace42:
With each G phone battery life is decreasing despite the architectural changes and slightly newer battery technology. G2's can top out at 7-9hrs SOT based on the battery thread, personally mine averaged 7.5hrs.

The G3/4 both have removable batteries, so LG can push that aspect instead of actual runtime.

[G4 General] Clay330i:
That's good info. I think the G4 is hopefully on par with Galaxy S5, maybe a little worse. That camera makes up for it though. [emoji1]
[G4 General] Dozenboy0012:
I came from the G3 I had great battery life there with the usual rooted phone tweaks like greenify, xposed and a few misc tweaks here and there. It's only my second day with this LG=H811 battey life seems good though i have not rooted yet but I can't wait to. Also got a QCOMM 2.0 fast charger by puregear for the fastcharge its supposed to be 75% faster well see

My battery life has been horrendous. This is my second charge.
[G4 General] automaddux:
I wish I could get 6-7 hours SOT but I can only get about 3-4. However, I did last 19+ hours and that's more than enough for me.

do you still have them? actually...do you still have the note 4, my question is the 7-8 hours you managed to get with the note 4 is it on lolipop?
[G4 General] Allesa:
Anyone knows how to enter LG secret menu on G4 equal to the 3845#*(model)* back in g3?

I have a strong suspicion fast dormancy killing my battery
[G4 General] AndroidCity:
I will post the battery life of my G4 later todat, but its not bad in comparison with the G3 ^^
[G4 General] Striball:
My G2 can usually pull off about 4 hours of SOT @ 40% left. If used efficiently it's usually about 45 minutes of SOT per 10% of battery, sometimes it's better but that's an average. Most I've gotten is 9 hours of SOT over a weekend and about 50 hours of usage. It's all stock rom and unrooted.

What I do when I reset the phone or basically any phone is go into Apps>All Apps and literally disable all the bloat I can possibly disable because there's 0% chance I'd use them and that cuts back on idle usage.

I'm wondering if this is something everyone does and if done on the G4, would it yield results?

Also what's pretty neat about the G2 that the G3 and looks like the G4 doesn't have is a widget to clear RAM. It was taken out after the G2 and basically after every time I close out of an app unless I need it later, I close it and then clear the RAM. Usually I can keep around 750-800Mb free and once it gets down to 500Mb and down I restart the phone and start fresh from 1.1Gb.

Battery life is towards the Galaxy S6 than my Galaxy Note 4 but 5 hours SOT on WiFi only isn't too bad.

Just got my LG G4. Loving it so far. Except a massive battery drain last night. I an on my second cycle and charged the phone to 100% and went to bed. When i woke up there was 48% left. This is way to much.

I have BT on (smartwatch), WiFi on, Data on. But never had this with my HTC M8 i had before. Any ideas what to disable? I already did a reboot so will see how that goes

[G4 General] Magnus3D:
My battery barely lasts eight hours as i use the camera all the time and rarely have any phonecalls, texts and moderate amount of social media usage. I guess it's my heavy screen usage which drains it so quickly, which is why i always keep a charger in my pocket now. :(

I had a similar problem on my S5 recently. I used the "adb shell dumpsys power" command and looked for wake lock. Turns out it was my Google backup and a restart fixed it.
