Lg g3 battery drain issue [ Tried normal methods % have screen shots ] - G3 Q&A, Help & Troubleshooting

Guys im sorry but i have rushed a few replies to get the 10 posts but can you please not take this down i need to know if this is legit as my money back only lasts a certain amount
Ok so i bought a lg g3 from ebay, Its legit i have tested with antutu officer but it can get really hot and battery drains very quickly when watching movies and games.
My screen usage is always above 60% but i have screen on 30 seconds and 0% bright. My phone also says that i have used like 1000 mah at 50% but it should say 1500 mah.
I have a d851 and marshmallow and use my phone only with wifi no gps/nfc i also dont have background apps
My phone gets 188 mins on gfxbench

Why should it say 1500 mah? The screen is not the only thing that drains the battery, you know that, right?
Running any benchmark will cause many battery drain. Don't do that. And that app you have to see the cpu temperature, 42º is not high for CPU. For battery it is.

What help? Get a new battery or go away from Snapdragon devices. And, the screen usage is about right, because i don't know if you know, but the screen you are staring at is 1440x2560, or 2K, which is an insane resolution, and crammed in a 5.5 inch display at 538 ppi, it will consume A LOT. And the battery is just 3AH, which seemed much, but compared to the S5, with a 1080p display and a 2.6AH battery, the G3 has the worst SOT out of the 2014 flagship lineup.

The 2K screen doesn't consume that much power. There are mods which allow you to lower the resolution, but you won't see much or any increase in battery life or performance (maybe in games it's going to be most noticeable).

Sounds like a bad battery. Quite possibly a reason why the other person decided to sell it in the first place. How old is the device that you purchases?
You can get an original replacement battery online for a few dollars. Just make sure you use a reputable vendor, like LG's official website.

Its brand new thats why i'm worried and i have downloaded a few battery checking apps and they say battery health is good.
But when i add up usage it totals lower then the battery capacity, they total up to 1000mah at 50%, when it should be 1500mah
Do you have any benchmarks i can try so i can see if its working right or its just me.

Oh so it's a brand new LG? How many hours of screen usage are you getting, what usage (web browsing, checking email or playing games?) and with what period of idle time.
Don't trust the numbers in the battery stats, especially in a new ROM. They are supposed to get better over time but I've found them to be wildly inaccurate even on months old ROM. I haven't really found an application you can benchmark accurately with.
But you compare with other (real) results on the foruns and rather you get the hang of what's the normal usage you should be getting out of a good battery.

Did you make a day without running any benchmark apps? What is your SOT? Standby time? Do you have location,wifi,bluetooth,NFC,mobile data on?
All of this matters. You shouldn't start right away with "I have problems with my battery" if you are running benchmark apps. Benchmark apps drains battery!
Wait a few days without running that apps and see how it manages. Another thing. The battery stats, the mah usage, not all of the things appears in the default android battery stats. And another thing, the battery value (the percentage of the battery), it is an approximation. Sometimes it could go up without charging, it is because it detected that has a wrong value. You could try charge your phone to 100%, usage it normally until 0%, until it turns off. Then charge it again to 100% and use it normally (don't discharge to 0% to many times, it just hurts the battery).

Streamed from the internet with at least 1h10 SOT, that is not bad. That is almost 4 hours SOT. If you have 1h12 minutes SOT, that is 4 hours. It is good.

Oh yeah, considering you even streamed the movie, it's signs of a good new and healthy battery. 3 hours of SoT with internet browsing is quite the norm, and 4 hours is on the up side.
I can barely get to 2 hours of SoT with my now aging battery.

It's not about the software side of things, it's about that my battery is old now, and that's why happens to old batteries, the just deteriorate.
Thankfully the LG G3 has an easily replaceable battery, and I have a replacement waiting for me. Not getting a phone on which you can't remove the battery..
And never found those apps like Greenify to really work, at least in the last few years of Android. The OS seems to be doing just of a good a job and I see no improvement in battery life. Maybe they help in cases with poorly written apps that are draining your battery in the background, but I don't see why would you use such a software in the first place.

You can lower your brightness if it is not already at the lowest setting.
Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?
I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.
hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...
I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.
sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...
Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.
GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen
hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........

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

gaming battery life

Dear nexus 7 FHD owners,
I have possessed my shiny new nexus 7 since tuesday last week, and boy am I happy with it. The only flaw it has is a dead (black) pixel in the lower left corner, which is covered by the soft button bar when in landscape.
While it is a fantastic tablet, I consider my battery life very weak. While I dont have exact numbers at hand, using google chrome to browse the interwebz drains the battery very quick imo (ill post on this in the future).
I do, however, have exact numbers on gaming. Yesterday I drained the battery from 100% to 14%, playing eternity warriors 2 for 3h14m straight, With a screen on time of 4h47m, of which an hour at the lowest brightness setting and the rest at 10-25%. Do these numbers seem to you? How much gaming time do you get on a single charge?
Idle drain seems about right, i left it at 88% when i went to bed last night, waking up with a charge of 85%. This is with wifi on in sleep, wifi and mobile network location on, currents disabled and all sync apps set to once/ hour. Though surprisingly when i tested the idle time during the day, leaving wifi off but all other settings unchanged, it drained 5% during my 6 hour school day, leaving the device at home.
I also played galaxy on fire 2 HD for 2h36m straight, draining the battery from 80-1% (i did maybe 10minutes worth of browsing in between).
I should mention that out of the box I had about 50% battery and I drained it to 1% on the first use before the first charge. I know this is bad for the battery, but it is said that most devices get their first full 100% charge in the factory right? Still though, might this have an impact on my battery life?
I'm looking forward to your feedback. The return policy ends tuesday next week, and I can return the device no questions asked until then. I will do that if it turns out my device's battery life is indeed quite the exception. I'm reluctant to do this, however, since I only have one dead pixel and I am afraid I might receive a device which has other or more flaws.
Your device's battery performance is pretty normal on the 2nd gen N7. Games seem to drain the battery the most. I get the same results. 3hrs with gaming. Worms Armageddon in my case. I usually get about 5-6 hrs od mixed screen-on use on a single charge. From what I observe Chrome will usually flatten the battery in 4-5 hrs depends on what pages you browse. The longest battery life you will get on video playback - up to 10 hrs with MXPlayer. That all on autobrightness.
I find these results a little disappointing. At least they are very far away from what is advertised. I do not know what is the biggest drain factor but I suspect the GPU and the wireless connectivity.
While transfering large video files over wifi between my nexus and an iPad it seems that the nexus uses more battery with screen off than the iPad with sceen on.

Thanks for your reply. It is really comforting that it's not just my device. Still considering a return for the dead pixel more and more, though.
RAM Hungry Games
I avoid RAM-Hungry activity. Mostly 3D games of course, drain my battery quickly when I have other services running, and the games that demand a lot of RAM at once will suck the juice out of that battery, so I usually keep it on the charger when playing demanding games.

How quickly does your battery drain when not plugged in though?
wow, such nice battery life, and complaining
Mine drained in about 1.5 days last week with a bit of usage, with wifi on the whole time. Charged from 11%. No sync.
todays results
Today my battery was drained in: 1.5 hour gaming, 1 hour chrome, 5 hours screen on time.
I find these numbers quite the disappointment.

That does seem a little low to me. I don't do a lot of gaming (Tapped Out is about it) but I have a lot of on screen time between Kindle, web browsing and Netflix. This is all anecdotal though, I haven't actually measured how good my battery life has been, it just seems to be good to me.
Are you running a custom ROM? I'm running CM10.2 and I *think* battery life got better when I flashed it. But again, I didn't measure and compare so its just a gut feeling.

I'm running full stock. My stand by time is actually pretty good (1% overnight last night), but thats probably because ive disabled most power hungry features (location, wifi off in sleep etc).
While i do a lot of gaming and battery life is expected to be low then, I expected at least 4 to 5 hours worth of gaming, since it is advertised it should last 9 hours when viewing 1080p video (which is not streamed)

Bad assumption. The hardware video decoder is extremely efficient (at 0% brightness I measured 1.28W power consumption for 720p; equivalent to 11.7h battery life).
The CPU/GPU hits thermal throttling (not enough cooling to run at full speed) at about 5W power consumption (= 3h battery life). Going from 0% brightness to 100% brightness adds another 1.05W (total of 6.05W = 2.5h battery life). So a game that heavily loads the N7, can very quickly drain the battery.

Thank you for settling this problem with actual facts! IIRC the battery capacity was indeed 15Wh, though I didn't know max. usage was 5W, I thought it was more like 3-4W.
I'm a bit curious though as to how one monitors the system power consumption. Is ther an app for that?

I'm measuring via the USB port (I built a power monitor).
The N7 also has a battery gauge chip that can measure current. The driver logs some debug info, including a current drawn value every 60s. However, that value is only the average for one second, so it's not very stable.
In a root terminal, you can run
Code:
dmesg | grep bq27541
to get the debug info from the battery gauge chip.
(BTW, that current is the current flowing into or out of the battery, not the current used by the system.)

I use Battery Monitor Widget. Among many other graphs it provides a %/h graph. I can see in games my N7 drains at ~30%/h

Great explanation. Thanks. What is then happening in Chrome? It's the 2nd biggest battery drainer for me. From what I can see it drains battery at the rate of 20-25% per hour.

Chrome is a CPU pig. Even sitting around on a web page with a single animated GIF will eat 1.8W at 0% brightness. Add in some web pages with a lot of Javascript (Javascript is extremely CPU inefficient) or not using an ad blocker (it's pretty common to to pull in ad-related Javascript junk from 20+ places on a single page and a lot of ads include animated crap) and you quickly get a lot more...

G Pro Kitkat Battery hogs

is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.
The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.
Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.
I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.
Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.
Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.
If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

Question S21 fe battery life

Hi all, I've just bought a refurbished s21 fe and was a bit surprised to see that it uses about 1% of battery every 4 - 5 minutes with the screen on. So the battery only lasts about 8 1/2 hours of mixed use screen time.
I wanted to ask if this was normal for this phone or do I have a poor battery? AccuBattery says that battery health is 95%
If it's running warm or hot it's not the battery that's the issue... yet.
Find the power hogs; either eliminate them or tone them down. Keep display brightness at 50% or lower.
Should have said it's a sd888 version and not using 5g
Phone doesn't get very warm

What the actual current drain?
If it's constantly drawing 400-500+ milliamps at idle it going to suck the battery down fast.
Currently averaging 295mA/h but battery has just been charged. I'll post again once battery is drained.

That's reasonable. If the battery has gotten to 80% of it's original capacity it's reached the end of its usable service life and should be replaced.
It's not a big deal... unless you don't replace it and it fails which can damage or destroy the device. Any battery swelling is a failure.
In a heavily used device the battery will last 1-3 years with 2 years being the average.
Thanks. Accubattery app says that battery capacity is 95% so it should have plenty of life in it yet, if that figure is to be believed.
Just checked today's figures. it's using just under 500 mAh with screen on and 85 mAh with screen off. This thing is seriously power hungry.

85 mAh is very excessive if AOD is set to tap on.
Google backup and cloud apps are prime suspects.
My apologies, I think I read it wrong. Just checked and it now says 120 mAh used in 5h screen off, so just 24mA per hour. The app reports a bit strangely.

That's a good result if cell and data services a on.
So it's somethings that are running with the display on that are chewing into the SOT.

What's the actual usage for SOT and for screen off? Accubattery history is very useful to monitor gross usage and establish a baseline.
Example, it's getting about 11%@hr SOT now. That's normal for this N10+ with a battery that's reached the end of its service life (approx 3200mAh). With a new battery those stats would be about 6-8% instead if using mostly Brave browser over 3 hour, 13 minute period.

While you see the screenshot you see a normal battery life ?
Start by turning off Global power management, it never worked right. Then go after the power hogs on an individual, case by case basis.
Set power to Optimized and try these power management settings:
Now go power hog hunting...
Uninstall the trashware. Stoiximan and all social media, sales apps. They are using a lot of resources. Login to them usingy a secure browser like Brave instead.
Google play Services and its dependencies Playstore, Gmail and Backup Transport can suck a lot of battery even when the phone is sleeping.
I normally temporarily disable Google play Services unless I need to use Gmail. I don't use Google (except gmail) or Samsung cloud anything so all cloud system apps are disabled.
Google Framework and Quick Search box are always disabled. The parasite Bixby never runs, always disabled.
A logging firewall can show you which apps are accessing the internet (and using power) when they should be at complete idle in spite of the app settings.
Galaxy Battery Tracker is a useful tool:
Set AOD to tap on. The power consumption when sleeping should be >.5% @hr, if higher something is running in the background. Likely Google backup Transport.
Use Package Disabler or abd edits to block apps that can't be dealt with using their settings or can't be uninstalled. I package disable about 70.
Be very careful what you disable; target only the power hogs and totally worthless apps like Digital Wellbeing. Dependencies... don't go too nuts or you'll destroy the functionality of the UI. Leave the many smaller Samsung system apps alone except for -known- bloatware you don't use. Try to know what you're disabling does and its dependencies if any. Do Not use other people's shotgun lists, create your own based on your requirements. This takes a while

Looking at Accubattery history.
It shows say 30% used. If it shows SOT to be say 3 hours then it's getting about 10%@hr SOT.
After a while doing this becomes second nature.
Can be used to easily see how much was used when sleeping overnight too (give some charge then turn off display for the night, see how much was used in the morning).
