My Mom's GS3 is dying fast. I think it's LTE but I may be wrong.

OK, so my wife and I both have GS3's through T-Mobile and our batteries last very long. I'm a heavy user and get a fully day while my wife is a light user and easily get's two days. My Mom on the other hand has her GS3 through Verizon and her battery is dying in roughly half a day. She is not a heavy user at all. In fact, her old Droid 2 would last longer than her GS3 which really has her frustrated.
I think it may be due to the fact she doesn't get a good 4G signal at work and at home. In fact, she gets 1 bar at work if she's lucky. She also said the phone is constantly bouncing back and forth between 3G and 4G while at work. She took it to Verizon today and they swapped SIM cards to be sure that wasn't the problem. Obviously that didn't work because I'm posting here. I will see her on Thursday and she want's me to look at her phone.
Do you guy's think this is most likely the reason as to why her battery is draining so fast? Also, if it is. Would there be a way I can show her how to disable 4G so her battery lasts longer?

It's most likely 3G and 4G switching back and forth or a rogue app. For to turn off the 4G it can't be done without rooting I'm pretty sure.

No, it's because you have task running. I had the same thing happen to me. If you exit an application by pressing home, the program will continue to run in the background. I had gallery take up 38% of my battery life. If you press the back button, it will FC the application.
Good bye HTC Rezound, hello Galaxy S3!

I'm on verizon as well and I find that my battery dies extremely fast. Full charge in the morning and by bedtime its just about dead, that's with moderate use. Some things that I have found to help is I generally keep bluetooth, and gps off unless I need either. I keep power saving mode on, and really minimized what Sync's through my accounts.
It's not exactly the answer you were looking for but it should help you until a more long term solution can be figured out.

Does anyone know how to turn 4G off?

Low tower signal will kill the battery very fast. Frustratingly fast. I have Verizon GS3, have very low signal at work, and I burn 8% battery per hour when phone is idle. With almost no use, my battery is down to 30% by time I go home.
At home I have good tower signal and my battery drops very slow in idle, maybe 1% per hour. At both work and home I have WiFi connected and set to keep WiFi on during sleep always. Therefore I don't think it's data traffic / sync causing the issue. Instead its hyperactive radio hardware or firmware killing itself as it constantly finds/loses tower connection. The only thing I've been able to find to reduce the drain is going into airplane mode... which is obviously a terrible option.
Hope Samsung can improve this self devouring nature in the future!

go to the playstore and download "phone info" open it and go to device information
Swith the " lte/cdma/evdo" into cdma auto (PRL)
I also turn off 4g at work due to weak signal
VERIZON GALAXY S 3

I believe its a signal search at where she spends most of her time. At my work the signal is very bad and the phone goes from 100% to 20% in 10 hours without even touching the phone. Now I turn on airplane mode and it never drops the battery.
She can disable the data and find out how much that would save her

First make sure it's not a rogue app by going into Settings -> Battery, your top 2 battery usages should be Screen and Cell Standby. As long as you don't have some random app eating away at your battery then it's definitely signal strength related. Does she have Wi-Fi available at work? If so make sure she connects to it. I have a Verizon S3 and the battery life on this phone is better than any Android phone I've ever owned (and I've had a lot). I leave GPS and Bluetooth on all day and can easily get a full day with mid to heavy usage. The biggest thing would be to get her on Wi-Fi if available. This will stop the phone from constantly trying to poll data off a poor signal and significantly increase battery life. If no Wi-Fi available, then the above post would come into play, Phone Info app and switch into cdma to keep it locked into 3g will help, but only if there's a decent 3g signal. If the 3g signal is weak also, then you're not going to help anything, and she will just need to remember to turn data sync off while she's at work.

Try switching batteries to see if she has a defective battery. If thats not the case, then make Verizon give her a replacement S3.

Add me to the list of people who think its the signal search in low service areas.. I disabled 4G with the Phone Info app and my phone lasted way longer than before..
Since you pointed out she has a low signal, I wouldn't be surprised if that's the culprit..

Ahhh so it wasn't the battery itself?
When you got a replacement S3, did you go back to the same store where you had originally purchased them from or tried a different store?

I disabled 4G today at work with my stinky cell signal and my battery nose dived like usual. Therefore, if you have no signal, 3G/4G doesn't seem to matter. The radio hardware will still destroy itself happily.

Anyone know of a widget my Mom could use to disable data completely while she is at work?

Pull the task drawer down and uncheck mobile data. Why do you need a widget?

You might have a system process called "gsiff_daemon" draining the battery. I have that problem and others have reported that process has been draining their battery as well. Or it could be other have mentioned already, signal switching, rogue programs, etc.

Today at work I ran with mobile data off. I still had a really bad battery drain. Therefore the voice 3 g radio must be responsible. Not much we can do about that unless a new firmware comes out.

Another battery tip...

There's also an option in the settings>developer options to restrict how many processes are running in the background, and to kill an app after leaving it. The only problem I've noticed with the second option is that the fb app won't allow you to post a status, I think because it causes it to start a new activity, which kills the main fb activity when you leave it. But limiting the background stuff seems to have saved some more juice on top of only using 3g.

Naw man, at home I have good cell signal and have almost no idle drain. At work I have terrible signal and it drains like nuts. It's not an issue with apps, processes, services, etc.

let's talk battery..

so as it may be known, i came from an iPhone 4S and traded that for an HTC One X, i've had it for a little over a week and i really like it a lot BUT (you knew that was coming i think..) the battery is below par, i get about 3, on a real good day 4 hours of usage from a full charge. i only auto sync mail, screen is on 25% (also tried auto for a few days), when at home it's connected to WiFi, data off and when i go out the other way around, GPS and Bluetooth are off at all times. the main thing i do on my device is Twitter, Google+, Facebook and Instagram, + some light browsing the Internet. i understand the screen and processor take quite some battery but it's not cool to only be able to use the device about 3-4 hours before running empty. emailed the guy i traded with and he said he got about 7hrs, which would be awesome after dealing with 3-4 ;}
i am using Nova Launcher Prime, but prior to that when i ran Sense the battery was about the same. may just revert to stock to see how that will affect the battery, even though i will miss my widgets and setup. i also emailed HTC and was considering going to AT&T but since i traded the device i doubt they'll be much help.
what do you guys get... and what if anything did you do to improve it ?
thanks.

How much screen on time? 4 hours is nuts. I easily got 24 hours on stock, with light usage, maybe even a day and a half. The 2.2X versions firmwares seem to get better battery life. Just this morning I had just under 50% battery left after 24 hours, with 1 hour screen on time.
If screen brightness in on "Auto" turn that off, and set it to something like 40-50%. That should save you some, but doesn't account the type of battery drain you are talking about.
Might be some runaway processes. Or any possibility you are in a fringe LTE area?

on screen time is what i was reporting, round about 4 hours -which yea is pretty horrible i'd say. i even have the screen brightness lower; 25%. checked the processes and for what i know nothing out of the ordinary, but i'm a novice Android user so.. prior to yesterday i only used 4G when out, so at home i stayed on WiFi.
battery stats now:
- 76%
- 5h 8m 54s on battery
- screen on 59m 28s

Screen on time of 4 hours very normal, and its good for a smartphone. Everyone uses their phone differently, of course. But 4 hours of screen time gets most people through a day, and charge overnight. What type of screen on time did you get with the iPhone?

Your stats are very normal for this phone model. The One XL screen is gigantic, but isn't AMOLED and as such uses much more battery life to power than some other Android devices. I get ~3 hours of screen on time in a days use of battery, and that is about 10-15 hours away from a charger. From what I can gather of your usage, if you are looking to extend your battery life, the only thing to do is leave the screen off more.
Do you flash custom ROMs? If so, try a custom kernel that allows you to change the CPU governor and clock speeds. The processor in the One XL maxes out at 1.5GHz by default, but you can underclock it to 1.2GHz with no noticeable detriment to performance. Also you can set the minimum frequency to an even lower clock speed, which allows the phone to use even less power when idling. Finally, make sure that the CPU governor is set to Ondemand. Powersave actually doesn't save as much power as you would think!

my favorite part was when he compared a tiny 3.5" screen to a 4.7" screen and expected the same battery life, even though it is roughly the same

Firstly, 4 hours screen on time isn't bad at all. I'm sorry your only reference is an iPhone.
To get 6+ hours of onscreen time with this phone like I and many others get you will need to do two things. Firstly, flash a custom ROM. CleanROM 4.5 is a good one that's as close to stock as you're gonna get. The second thing you need to do is turn off auto brightness. Leave the brightness set at 35% - 40%. This will improve battery life immensely. And no, 40% brightness is not dim.
Happy flashing!

10-12 hours up

with my iPhone (GPS on always, WiFi always, screen on about 70-80%) i got an average of 6 hours with peaks of 7. 4 hours with the HTC One X is on a good day.

i did not flash a ROM since i can not unlock the phone (yet). where i compared, referred to the iPhone is based upon the previous owner who said he usually got 6-7 hours on screen per day. it's uncool that people not live by the rule if you don't have anything nice to say, don't say nothing... i'm only trying to get some help here (luckily most members are helpful... i'll try and ignore the others) and my other reference would be a BB Storm, which lasted very long, but the device wasn't very exciting
i'm following the thread where rooting is discussed but i believe there's little progress. AT&T is also not pushing Sense 4.1 (yet, mine has 4.0) and ICS 4.0.4.
just spoke with HTC and they agree it's too short and are willing to exchange battery... downside i would be w/o a phone for 7-10 business days. might swing by AT&T and discuss, "issue" is i was not the original buyer.. he (HTC rep) stated they might give you a loaner (i doubt it..) we shall see.
thanks to those with positive feedback.

so far..
click here for today's results --16% left.. slightly over 3hr on screen time.

It really depends on how you use your phone, and not all screen-on time is the same. 4 Hours is screen time is pretty good, and pretty on par with what other users on here have observed. The phone is new to you, so I bet you are using it like crazy. If that use includes a lot of internet, playing video, or games, its going to use more battery than some other activities. I don't know if a replacment is going to make you any happier.
You also have to consider, aside from a much larger screen, its also much higher resolution than the iPhone. Pushing all those pixels by the GPU takes power. The CPU is also much faster than the iPhone (and just about any other smartphone except the Galaxy S3), again using more power. Screen time may be less, but its doing so much more in that time.

4 hours, if I made would be somewhat acceptable, yesterday I had a little more then 3. I do not play game, I manly do social media & a little surfing..

The 2.20 OTA has an new radio. So its possible that the new radio happens to result in worse reception (and therefore battery life) than the previous one. Newer radios do not always get better results for all people, as its very geographically dependent.

Thank you for the reply and yes the radio looked like it was a new one and in PA i dont get that great of service everywhere.

Yeah, 4 hours of screen on time is normal so I definitely don't think you have any sort of defect. Signal strength also has a lot of impact on battery life. Keep brightness as low as possible while still being comfortable to your eyes (battery life isn't worth putting extra strain on your eyes). I use an app called display brightness that allows you to change brightness by swiping across the statusbar. I keep mine at the lowest level and just swipe a bit to increase it when I need it and then swipe it back down when I'm done. A custom rom could help some. If nothing else, root so that you can use something like better battery stats to give you more info on what's happening behind the scenes so you can make some adjustments. Although I'm not one to push using this, you might want to install something like juice defender to see if it helps. Verify you don't have some app running in the background unnecessarily chewing up cpu use. Note though that just because an app is running in the background doesn't mean you should kill it. As long as it's not doing anything, it's better for it to be running than to have to load it up (especially if it's an app you use frequently). A couple of other things to verify, don't use push notifications / syncing (I keep background syncing off a manually sync (well, I use Tasker to sync things at different times of the day)). If you can, use wifi. If wifi isn't available, turn it off. Also make sure wifi notifications are off and that you aren't using 'best wifi performance' (both under wifi advanced settings).
I'm sure there are some others I missed but hopefully these help and at least give you a starting place. No matter what though, enjoy your device and don't obsess too much with the battery. Once you've gotten over the 'new toy' syndrome, you should get a days use out of it. I pretty much take mine off charge in the morning and put it on charge before going to bed with around 30‰ left. Sometimes more, sometimes less. 3-4 hours average of screen on time, 30-60 minutes of calling.

update.
went to the AT&T Device Center (did not know it existed until the regular AT&T store told me about it...) they played with my phone and concluded that the battery was draining too fast while using it, so w/o discussion they exchanged it.
got a follow up question since AT&T did not know, with the iPhones i would let them drain all the way down at least and then fully recharge and leave it on the charger for an extra 2 hours after it being 100%, i *think* that helped condition the battery.. anything you guys can suggest anything for me to to now that i have a new device to maybe improve/condition the battery ?
thanks.

[Q] Awful battery life - just me?

I got my Nexus 5 on Monday and have been pretty happy with it so far. Today was the first day I actually had to be away from WiFi for the day and the battery life has stunned me with how poor it has been. I haven't seen battery drop so fast since I had my Desire HD. I took it off charge about 9am and at just after 8pm as I type this I'm down to 10% with under 2 hours screen on time. 100% to 10% in around 10 hours with less than 2 hours screen use.
Has anyone else had this poor battery life? I'm going to let it run down completely, install GSam and see if it happens again but from what I've read on a few reviews (The Verge was the main one) this seems to be almost normal. I would be unhappy with battery life this bad after two years, not two days.

The good battery apps like BBS are broken on KitKat.
But your battery life is not normal. Mine is quite good, about what I would expect. For reference, my GS3 would use 0.2-0.4% per hour while idling during the night. I can't get real numbers or monitor wakelocks on this phone yet. But so far, seems at least somewhat similar to that.
Use Greenify.

A brief summary of my brief usage. I haven't played any games at all since I got the phone and the only usage has been social network apps and very light browsing of around <20 minutes. Oh and I made a call that lasted around 15 seconds. Everything else is stock setup. I have unlocked the bootloader but I did that prior to setting it up due to it wiping everything in the process.
Basically I've used it as much as I'd use my Nexus 4 and that wouldn't see so much as a 30% drain by now. The only thing that I am looking at as a possible cause is that the phone defaults to wanting 4G only. I'm not on a 4G plan or in a 4G area but even with that Mobile Standby is only showing 4% battery use. Suffice to say I switched that to 3G when I saw it just before posting. As I said, I'm going to drain it completely then charge to full and watch it very closely but I wanted to get thoughts while I waited.
I have contacted Google to see if there are any known issues that have popped up but the response I got just suggests turning off practically everything! Why would I opt for a powerful phone just to turn off sync, location services and anything that makes it a smartphone? The baffling one to me is suggesting I switch to AIRPLANE mode if I'm not near WiFi! I didn't buy a WiFi only tablet, I bought a phone!
"If you know you won’t be near a mobile or Wi-Fi network for a while, switch to Airplane mode"

I have been very pleasantly surprised with the battery life with my Nexus 5, I have noticed however that Google Location service likes to use battery power, more importantly - GPS - way too much..
However, I leave it on and even still it easily lasts me a day of use, with around 30-40% left depending on how much I use it.
What are your highest apps in the battery use screen?
Try turning off Google location services.

I am really pleased with battery life. Around 30-40 % left at end of day.

I saw similar with the Nexus 4 but refused to switch off location services and it seems ok. I've attached screenshots just taken. It seems I was a little off with my browsing estimate which shows 36 minutes in Chrome but still hardly astronomical.

OK so far the general opinion seems to be that it's just me. That helps me eliminate the phone and / or battery just being awful so thanks guys.

I'm at near 11 hours and am at 69%.. with an hour screen time. Not great but it easily gets me through the day. By the time I plug it in tonight it will probably have 20-30% and 3 maybe 4 hours of OST. That's more than enough for me
I should mention I have location off.. and only turn it on if I'm going to use the GPS
I also have Google Now off I don't need those flash cards to tell me how long it's going to take me to get home.. it's useful sometimes but I rarely look at em.
I'm pleased with my battery so far.. for the super heavy user they definitely wouldn't get a day.. but for me I'll get it easily.

its been pretty terrible for me with identical setups as other devices.
it has me seriously contemplating going back to my htc one. overall i do love the phone tho so hopefully I get a better idea when betterbatterystats is updated.
Few things with battery thats annoying me is google services kill this phone worse than any other ive owned. Even with google now disabled and location disabled. Also my daily drive to work I always use waze w/ screen on. With my other phones (htc one / n4 / iphone 5) i generally lose between 10-15% battery. On this phone im easily losing 25%.
I have access to charging so not a huge deal for now. Its a new os update so maybe it will get ironed out.

you are forgetting you are having a full HD and quad core phone now.

Ahh you got that google services bug eh.. that will kill any battery

Despite not wanting to I did a factory reset and installed a handful of apps, nothing that should cause issues anyway. When I got to Twitter though just after installing I noticed two warning notifications crop up that I remember just dismissing without thinking last time.
com.google.android.gsf.login
com.google.android.calendar
Both state they need installation of Google Play Services. I've ignored them for now so it'll be interesting to see if they have anything to do with it. I know the screen is going to be using more battery than I'm used to when it's on and notice that in battery use it's just everything else.
Friday will be the ultimate test of sorts. I've disabled WiFi, I'm charging it up and have disabled a few location things I don't care about. If it goes down hard again then it's going back.

I don't think what you're getting is that out of the ordinary. Between screen time and cell reception (the largest contributors to battery life) you could easily be seeing 'normal' battery life.
Don't expect more than 3.5 hrs of screen time, especially if you have reception issues when not on WIFI. And I'm talking 'normal' computer/dev/IT guy usage (e.g. using the phone as it's intended aka using google now, using one or two emails with push sync, using music services occasionally and sparingly during a day, NOT running in airplane mode, not disabling a crapload of smartphone features).

Marshmellow Upgrade | Awful Battery Life

Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.

Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.

I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.

Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.

My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.

All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.

My battery life is 4x better. I couldn't be happier.

Been on MM for about five days now and my battery blows, so much worse than what it was!

Mine is exactly 4 times worse

Battery the same.
But I have to tap the screen harder to chose app.
Going to factory reset and start clean, been a while.

Has Verizon released any new updates to patch the issues with Marsh Mellow update

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.

I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.

I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.

Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.

New T-Mobile G5 - poor battery life/unlock

Hi guys, wondering if anyone can help
I bought a new unlocked T-Mobile LG G5 from ebay last week for my wife, after buying it I didn't realize that the unlock code is a software unlock, not a SIM unlock, and that I am not able to flash to the stock LG firmware if I want to keep the unlock on hand.
I was looking at flashing to stock because the battery life is quite poor for a new phone, much worse than my S7 Edge, even though she doesnt do anything crazy on it. Are there any tips or tricks to improve the battery life, its using H83020i_un software with what appears to be the regular/default T-Mobile stock apps...
Any help would be appreciated, either regarding the battery, the unlock, or both. Also, will I get any OTA updates, and if I do will it re-lock the phone? Im in Canada btw
Thanks

There is a thread covering all the ins and outs of the 20i_un custom SIM unlock ROM. Everything about locking and updates is thoroughly discussed 1 thread up from this one.
About battery life, that ROM shouldn't be impacting battery life. You should get 4 hours of screen on time (roughly) per charge. If that's not enough to get you through the day, then this isn't the phone for you.
If you aren't getting 4 hours of screen on time, something is wrong. It's not the ROM because the ROM is PROBABLY the stock ROM with 1 small modification for SIM unlock.
Things like Facebook are NOTORIOUS battery drainers so if you run a lot of apps like that, they could be hurting you. Have you looked at your battery stats? Do any apps jump out as taking up a lot of battery? Is it the Android system that's using the battery?
Android's battery stats chart will tell you a lot about what it using your battery. We'd need to know what it is before we could suggest fixes.
Also...be sure to leave the seller negative feedback on eBay. This phone was misrepresented on eBay, even after they were aware if was not factory sealed and had been modified. They lied about how many they had too, saying they were nearly out of stock at least a thousand units ago. That's deceptive advertising. They lied to multiple people about putting that second clear seal over the broken factory seal. And they contacted at least me outside of the eBay message system which is a blatant violation of the eBay terms of service. Even if you keep it, the seller deserves negative feedback.

Yeah I did notice that about the seal when I opened mine.
I noticed the battery drains alot while idling, not sure what could cause that though...

Well...look at the battery stats charge in the settings. It will tell you what's using the battery.
Are you using the Always On Display? If so that's your answer. That chews up battery like crazy at around 0.8% per hour. Conversely I get 0.1% to 0.2% drain per hour on idle with the Always On Display turned off.
I'm also a fan of Greenify for putting the phone into Doze mode after minutes rather than an hour or two like Android does natively. I'm not a huge fan of Greenify as a task killer as that's counterproductive in most cases. Though I do let it kill an annoying persistent Major League Baseball app that I like but that doesn't know when to shut up.

Always on display is off, using greenify, helped a bit, but I notice that most of the battery usage % is "Phone Idleing"

Agree, in the past month or so, my LG G5 battery life has become noticeably worse. The top two battery burners are Android OS and Phone Idle. I've tried multiple hard resets, clearing cache, etc, but nothing seems to help. I haven't shut off the always on display, but it wasn't shut down before. Something has changed recently, maybe in the last update, but the battery life is terrible now. Any help would be appreciated.

If youre on 20k update, then I agree. Battery life was fine until 20k update. Now I cant get through lunch. Battery stats is not helpful. Shows no issues.

Were you ever able to solve the battery problem?

There are a couple of comments on the previous page that Phone Idle is a large consumer. That happens when you pick the wrong carrier, and the signal is weak most of the places you spend time. When that happens, it's assumed that the phone's signal will be weak at the tower, so the phone transmits at maximum power - and that kills a battery fast. Choose a carrier that has solid green in the battery stats (tap the graph to get to that page, then scroll down). That's the first thing you should do when choosing a carrier - not that they're the only ones carrying this great new phone so far, but that they give you a solid signal where you spend most of your time. And it's exactly what most people don't do (because they're not aware of it). (And the phone matters too - some just have more sensitive receivers than others.)
