Re: Why is "Android System" using up so much of my battery?

I keep my gps off all the time unless I need it for maps etc...

Its actually still on even without the icon showing

Please explain, trying to understand. I know that somehow it has some sort of built in location gps for for emergencies but I can't find it if I turn off my location services

It's in the play store under LG access permission control

Many thanks, couldn't find it under LG Access Lock and thought it was something that came from LG.

Re: My LG G4 is stuck at 80 battery and isn't recognizing my sim card. What could the issue be?

Are any of you using 3rd party batteries? I noticed this issue today on my G4 but it went back to normal after putting my stock battery back in.

Battery Indicator Problem

When I charge my LG G4 to 100% the battery discharge so weird, it discharges from 100% to 85% the 1% takes 8 min and when it reaches 85% to 75% the 1% takes only 2 min and from 75% to 0% the 1% takes 3 min, so I think the battery indicator is the problem because the battery is good and still new I'm pretty sure about that, so can you help me with this problem and how to fix it.
Thanks.

Re: Battery Indicator Problem

It seems to be that it is not calibrated.

Also when using a new battery, you have to note that it takes at least 10 charges to get the full capacity.

Re: My Final Word On G4 Battery Life

I'm just going by my personal experience, and that of others that use lithium batteries. The OEM in my Bionic was toast in less than a year when using my old charging practices. I replaced it with an extended battery that lasted over a year with my current charging before I shelved it. I put the battery at about 60% storage charge when I upgraded to my M8. I'm back on the Bionic nearly two years later because said M8 is dead and waiting on my G4. Battery life is just as good as when it was shelved.

This just crossed my radar last night:

Fact or Fiction: Is it Harmful to Keep Your Phone Plugged-in Once it's Fully Charged?

The executive summary is that it's not harmful to keep your phone plugged in after it reaches full charge. Modern phones run off the charger's juice once the battery is full. Charging overnight should not harm a battery's life in the slightest.

What does shorten the battery's life, is charging too frequently.

Re: My Final Word On G4 Battery Life

I installed gsam recently to see what I've been getting as my daily use has seemed to level out a bit.
I'm pleased with the life I'm getting so far.
Lux I think is beneficial... seems to help keep the power hungry screen brightness under control better than the default LG brightness automation.
I've been using Nova Launcher, have the usual social apps installed but with sync off. (I do keep sync enabled with Gmail, it's a must for me)
I have Quick Chargers kicking around (home/car/office) when needed so I don't really have to plug it in over night.
(additionally, I listen to music on it via power amp for at least 4 hrs per day 5 days a week)

I know this was covered on Battery University's site. With all the info there, it may take me a bit to find the exact articles to link here. In short, a high charge level doesn't mean over charged. It's above the point where extended periods can prematurely shorted a battery's life. Generally, this is 4.1V, which correlates to about a 75% charge level. All Li-ion battery chargers are designed to stop charging once full, so that has no bearing on this. Leaving a phone plugged in overnight is no different (chemically speaking about the battery) than fully charging the battery and removing it from the phone all together.

Saying frequent charging shortens its life is technically true but not in the way your article mentioned. Lithium batteries have a certain number of full charge cycles on them, but they aren't affected by short charges like older technologies. All things being equal, a lithium battery is affected by two half charge cycles the same as one full cycle. If you're a power user and doing multiple full charges a day, well then yes the battery will wear out quicker. Only that's a symptom of the heavy use, not how frequently it's plugged in.

I'm confused. I thought upthread you said I shouldn't charge my battery overnight, because once fully charged it would sit for 6 hours still plugged in, and that would degrade the battery over time. The article says that isn't true. Did I misread something in your earlier comments?

Maybe I'm misundersatanding you.

You read me right and what I'm getting at more or less amounts to semantics. Not sure where that writer got her info, but she's wrong from everything I've read and experienced. The article is no longer there for me, so I can't double check her exact quote. She is right that the phone won't overcharge the battery, but that isn't the issue. The issue is being at a high charge level, above 4.1V (for standard Li-ion, though I think the G4 uses a higher rated construction), for extended periods. Leaving the phone plugged in would keep it right at the 4.2V or whatever the designed limit. Storing a battery like that will reduce its life. If you do that nightly, it'll still have an effect but not all at once. It'll spread it out over time. The average consumer may not notice this.

I did find a couple of articles discussing these issues in depth at BU.

Re: My Final Word On G4 Battery Life

The most screen on time that I got was about 7 1/2 hours but this was due to Sprint sending out a system update with a system notification which turned on my screen and kept it on while I was sleeping so nothing else was really going on with the phone during the time.

I keep my phone at auto brightness at 80% and most of the time battery usage for the screen is in single digit percentages when I go to recharge. Even that time I had the overnight screen on issue due to the Spint notification the screen only used about 35% of the battery.

The screen on this thing is amazingly efficient.

That is definately a first. I doubt that would happen again though.

Charging Lithium-Ion Batteries – Battery University

How to Prolong Lithium-based Batteries - Battery University

Thanks for the links. Judging from the comments below the artciles, they look to be 5 years old in both cases. That is an eternity in tech years. I realize that batteries are still lithium ion, but I have to think the batteries from 2010 are not the same as those we have today. We know the tech using them isn't.

I'm no expert on this issue. I'm not trying to suggest otherwise. However, this type of thing is to what I've referred before: very old info still being used as gospel. Now, perhaps nothing has changed from a practical standpoint, but I doubt that very much.

I'll go back to my own experiences. Nothing I've experienced suggests to me that the way I've charged my phone is an issue in even a modest way. Unless the suggestion is that the decline in my battery over the ~4 months I've had the G4 is because of this supposed degradation of batteries (which isn't what you've been suggesting). That would be a first on any phone I've had, and quite coi8ncidental given the drops lining up with other types of specific events (FDR, OTA update).

Re: My Final Word On G4 Battery Life

There's always exceptions to every rule, and every battery will decay at different rates for different reasons. I'm mostly speaking about the big picture. I've heard of system updates hurting battery life, so maybe something goofy happened during your FDR that did the same. I will say it's the first I've heard of it, which is what had me questioning it.

While the comments in my articles are old, the bottom of the actual articles show both were updated this year. So if things have changed, such as not being harmed by dwelling above 4.1V, I'd think they'd have mentioned it. In following an R/C hobby using lithiums, I've been somewhat kept up to date by reading others experiences. Despite ever progressing technologies, charging practices have remained mostly the same. Many of those guys go so far as to measure actual mAh put back into a battery after use and the internal resistance to determine battery health. That's more in depth than we can do with phone batteries, so I'll stick with the prevailing habits. I'm also not aware of other sites as dedicated as Battery University. If you know of similar sites, I'd be happy to check them out and compare notes.

Re: My LG G4 is stuck at 80 battery and isn't recognizing my sim card. What could the issue be?

I had the issue too as it would randomly get stick at 74%/75% and won't charge further even in safe mode, charges fine with phone completely off. The other day, it was stuck at 97% and finally made it to 100% after 2 hours so it was charging slower. I remember reading this phone charges fast and then switches to a slow mode, perhaps that's where the problem is as maybe the switching got stuck or something.

Re: Battery Drain

I have the same problem. Android system consumes most of my battery. How did you fix it?

Re: Why is "Android System" using up so much of my battery?

Please explain, trying to understand. I know that somehow it has some sort of built in location gps for for emergencies but I can't find it if I turn off my location services

I have the same problem so after researching it that's been the general consensus. There are so many wakelock s caused by Google play services. Even though gps is manually turned off it is actually still on. Keeping it in battery saving mode yields much better battery consuption but mine started back again halfway through the battery cycle. I'll try to find the link to better explain it. Marshmallow should be completely updated to all g4s by the end of february and that's supposed to fix the problem. Not sure I can Waite the 6p is calling me

Re: Why is "Android System" using up so much of my battery?

I am on Sprint and if I have my wi-fi calling on, my android OS keeps pretty constant at 55-57% usage. If I turn wi-fi calling off, the Android OS runs between 11-13%. I have tested it many times, and everything seems to trigger on the wi-fi calling for me. My battery will go from 6 hours of lasting to well over 24 hours.

Re: Why is "Android System" using up so much of my battery?

The only reason it's high in your screen shot is because on this cycle u haven't used your phone much. If you notice your at 41 hours on this charge so the only thing using your battery is mostly android.
