Unfortunately I can not agree with you. The bug fixes and upgrades they made with the new update make this device better than it already was. No lag, No battery issues here.
The fact that you mentioned lag on keyboard and having battery drain in issues suggest you have something wrong. Something is running draining your battery and consuming the ram.
I would try I to reflash the phone again clean or do a factory reset and see if it helps.
If you are unsure of what to do and you are not rooted as it doesn't seem you are take it to local store have tech flash the phone clean.
If you want to do it yourself everything you need can be found here: http://forum.xda-developers.com/showthread.php?p=54912191
Have a great day! from my LG G3

[Q] Help, new to this

Hi, I downloaded and installed XWLPY NeatRom Lite v3.5 (18th October 2012)a couple of days ago and now my battery is draining extremely fast. I tried a couple of battery managers and nothing seems to work.
Anyone with any ideas on what I can do to remedy this? Plus I can't see the update section in my settings, is it removed with this software?

The ROM doesnt have an update because the devs have removed it because you just flash an update. As for the battery drain give it a few more days if the problem persists try another ROM. If it still persists after that try recalibrating the battery or resetting the fuel gauge chip.
Hope this helps

Hi,
NeatROM 3.5 is one of the best ROMs from battery backup perspective. And I can say that because I am using it since 3.5 came out and have never had any issues.
For a better battery life, follow the steps from the link,
http://forum.xda-developers.com/showpost.php?p=33045733&postcount=8776
Please note that the instructions are prepared to get the most out of your battery. Even if you follow the few ones that you are comfortable with, you will surely see some improvement.
Please press Thanks if this has helped you.

I agree with you .I use NeatRom 3.5 with Dorimanx, the best combination for me.

Its simple mate. Just download an app and hit a button.
Usually battery drain is due to one of two things.
-Phone not going into deep sleep
-Wakelocks.
Download an app like CPU spy. you can use it to see whether or not your phone is going into deep sleep like it should. Also, use better battery stats to look for wakelocks. Download the app from HERE , let it run for one battery cycle and then check for wakelocks. If you dont know what those are, spend some time reading that thread.
But if you want to hold off for a couple of days, you can do that. It does take some time for a phone battery to settle when a new rom/kernel has been installed, after which battery life tends to improve.

Thank you very much for your help mate. I've tried a couple of battery managers off play (juice defender and another one). Right now kind of regretting this download, everything seems to be going wrong;
1. battery is draining @ 15% in 20 mins ( I only bought the battery last week after having the phone unlocked).
2. there's a lot of lag
3. screens keep freezing and
4. keep losing reception and constantly having to restart phone.
I only downloaded this cause after unlocking my phone it failed to update. Is there any other that I can download that works well with SGS2?
There's no dearth of ROMs for the i9100 dude. Try a couple out and see if those help. If its stability you're after, maybe use an ICS Rom rather than JB.
15% in 20 mins isn't normal even for a first day..you sure it isn't a faulty battery right? Was it giving decent life before you switched to this ROM?
Try downloading a calibration app and see what the voltage is when it says its charged 100%. Should be around 4100-4200 mAh.
As for the lags and freezes, did you wipe data, cache etc before you installed this Rom?

I had cleared the cache in settings before installing. Like I said, my first time doing this. Seemed straight forward at the time.
Since my phone is unlocked, will it return to ics4.0.3 which is what I had before?
Battery calibration app is showing 4161mv.
Will a factory reset help?
Thanks for all the help, site can be a bit confusing sometimes lol.

Cache from settings? No. I meant clearing cache from the CWM recovery menu. If you installed the ROM via CWM, that is.
If you did, I'd suggest reinstalling it again via cwm this time clearing data, cache and dalvik cache.
Ok..I just realised I totally assumed you'd installed it using CWM. Not sure if you did.
You can return to 4.0.3 if you want. Download stock firmware from sammobile.com and install it via Odin. I'm sure there's a guide on how to do that somewhere on this site.
Just noticed someone posted instructions on maximising battery. Did you use those? It could explain the freezes if they started after that. Some phones just can't handle undervolting etc.

Morning, I downloaded some battery managers and seems to be working better and faster. Battery discharged 27% in 5 hours.
Will see how it goes over the next couple of days.
Teaches me a lesson to do my research first lol.
Below is a screen shot of the apps I installed.
Thanks and gave a great day!
Sent from my GT-I9100 using xda app-developers app
Haha that's a lotta apps just to save battery. As long as it helps eh? 27% in 5 hours is pretty acceptable for moderately heavy use. Depends on your signal strength and whether you're using data or on WiFi etc.

Battery drain, Cell Standby

Hello, I have new LG P760. First thing, what I've done was update to Jelly Bean. But I experiences battery drain. Everytime, when I look at battery stats, there is Cell Standby on a first place and second or third is System Iddle. I've done hard reset and phone recovery in LG support tool. The problem is still here. Can it be hardware problem? Is there someone with experience like that? Sorry for my english
Exactly same for me. It happened after JB update. I found that device stays active even screen is locked when mobile data are on (battery stats app).
Conditions: factory reset after update, no additional apps installed
I hope just a bug and will be fixed soon.
Hello guys,
According to my experience, I think this is happening with you coz both of you flashed JB rom which is not for your country, there is no any solution to this problem until you got jb update for your own country.
I also faced same problem and got solved after update for my country (india).

ok guys
Now that may be a bug in update.
So I suggest you to take your phone to customer care or you can call someone at LG Care.

Same problem i am facing and its very poor experience!!
Same here ...
I think Mine condition is worse... I am on indian version of jelly bean. Battery stats shows 45 % cell standby and 45% phone idle....only 8%screen
Should i go to lg care
Sent from my LG-P765 using xda app-developers app
it seems like it is happening on all jellybean roms on all countries..
i also use official jb rom for my country (indonesia) and yes the cell standby and system idle totally drain my battery
well if this bothers you that much then maybe revert back to ICS is the best solution
Its exactly the same problem for me too!
I'm using official JB update (austria) and for me its the same too!
This isn't a nice experience!
Sent from my LG-P760 using xda app-developers app
Yeah I've noticed a increase in battery drain on my P769 running V20D.
On ICS my battery would last 2 to 4 days on average, but on JB I can barely get 2 days
Same here
I updated my phone via wi-fi with the official rom. And had the same problem. Battery drain. So i downgraded back to ics. I prefer battery life instead of project butter and google now.:good:
Now I'm just guessing, but it could be the google now app. Try shutting it off or don't allow the google location stuff.
Many were talking about the Google Now service which was a battery drainer. You should try and see the results. I also tried it,and the top 2 consumers were still Cell Standby and Phone Idle.
This thread might help with the battery drain. I think csrow found the problem

This is the same experience I'm having after the recent JB update on my P769. Battery life is now about half of what it was on ICS. Cell Standby at 35%, Phone idle 22%, Screen 20%, Wifi 11%..
Used to have plenty of juice mod/heavy use, was quite impressive. Now I have to carry a charger.
I too experienced crazy battery drains after upgrading to JellyBean (OTA update, P769 T-Mobile prepaid, pure stock, not rooted). I tried turning off Google Now after reading this thread, but it didn't seem like it helped much.
Last night we decided that my wife is going to use the phone instead, so I factory reset the phone before I gave it to her so she can start over fresh with her google accounts, etc. She left home this morning with the phone fully charged, and when I came home from work in the evening I checked and she had more than 85% left! Granted she didn't use it much throughout the day as she still carries her old phone, but she did use the phone to make some phone calls/chat and take some pictures. Just as a comparison, the last time I had the phone with me before the factory reset, the phone was draining battery maybe about 15%/hour just sitting on my desk.
So, for those of you experiencing battery drains, maybe you can try doing a factory reset if you haven't. I realize this is not something most people want to do unless it's guaranteed it will fix the problem, but if it's as annoying as my experience, maybe it's worth to try.
cell standby 75% Screen at 17% no idle details on Tmobile USA

update: the wifi radio is always on change the setting as of csrows thread it is always on even if you dont have it clicked it has improved my battery some but much more is needed on alot of things im working on things ill update you all when i figure some things out
Just for those who don't know where this setting is:
System Settings >> Wi-Fi >> Click Menu button >> Choose Advanced
Change "Keep Wi-Fi on during sleep" option to "only when plugged in" (or "never" if you want).

Horrible battery after lollipop OTA

So the wife took the lollipop OTA... Since then she says her battery life is incredibly horrible. After only one hour of normal use it went from 100% to 35%
The biggest problem I'm having is figuring out what I can do. Typically I'd have rooted the phone, flashed a ROM & never worried about OTA. With that being said, she doesn't want her phone modified whatsoever. She wants it left completely 100% stock...
Anything I can do?

Verizon says ...
The Verizon info about the update, mentions that it may take several days for the new release to properly calibrate battery usage: http://www.verizonwireless.com/dam/support/pdf/system_update/instructions-lg-g3-4-14-15.pdf
Battery life expectations post a major OS upgrade:
The application memory areas may have to be optimized. This can take time and cause the device to temporarily use more battery while the optimization is in progress.
It can take time for the new software to optimize its performance and for the device’s battery life to normalize, which generally takes 2- 3 days.
Downloaded applications may not be optimized for the new OS version as application developers do not immediately update their applications to support new versions of the OS. This may result is higher than normal battery drain and in some cases device sluggishness until the application is updated or removed.
download greenify, works with not rooted phone too.
I was hoping to not use an app for it lol.
But I talked her into letting me root it so I'll just be doing that tomorrow.

Factory reset helped a lot for 2 g3's in my house.

Service randomly dropping

I have an AT&T H820. I've been having issues for about a month with my phone randomly going from having good service, then going to no service. Sometimes it'll cycle between the 2 for half an hour or so. I've done factory resets and even gotten a warranty replacement.
The only thing I can think of is possibly something to do with the battery since I had to use the one from the replaced G5. Since this has been happening the battery life is abysmal, even when it's not cycling between service and no service.
Any help is much appreciated!

Well its nothing to do with the battery. I bought a new genuine battery and it still will occasionally drop service. It must be a software issue or with an app unless I just got really unlucky with my warranty replacement phone.
I noticed looking in the battery usage there are a few things that have no descriptions as seen here: http://imgur.com/Zstdq7q Any idea what's going on there?

I also have those same 3 new mystery battery draining items since after the H82011K update, this software patch is S#!T. AT&T's customer support is abysmal when it comes to accountability for bad OTA's, I have contacted them about several other problems caused by H82011K and they tell me it's LG's fault (I think they're lying personally). I also noticed WIFI is wonky since that latest patch. So pretty much good luck to us and godspeed to the Android N update - hopefully it doesn't break this poor phone any further.

Seems everything is fine. And your battery is original too without problems. I have a solution for u for sure...
SOL1:- If you are rooted then go for app like Greenify where you can hibernate your apps like Spotify etc.
SOL 2:- If you know flashing then maybe yoy should flash a kernel. Or maybe a compatible ROM.
(Kernels like Decipher or Halogen are awesome) but check the compatibility.
Hage a good day. Cheers [emoji4]

That would be great if it was possible. Unfortunately we have the H820 (AT&T model) which is bootloader-locked and thus unrootable. Development on that is also apparently at a standstill if I'm not mistaken.

Bought a G930A factory unlocked and updated to Oreo, regretting everything

Title says it all, made the mistake of upgrading to Oreo and now stuck with relentless battery drain issues. Tried everything short of reflashing so far and failed. Nearly everything is disabled even after full wipe and reset (hard) and its still pretty bad in terms of battery life. So I signed up here looking for ways to salvage the hardware, perhaps by downgrading back to Nougat if I still can or installing something better and different altogether. I've read folks having luck with the cell standby drain by installing a nougat/oreo mash but couldn't find specific details on how to do this. Also this doesn't seem to fix the android system drain issue but its at least a start. I have basic experience using Kies and Odin, helped a couple relatives with boot looping tabs in the past. Please advise on the best path forward to make use of my new phone.
Have you tried installing 7.0?
What version of Oreo did you install? I myself installed a TMO Ver G930TUVU4CRI2 but running on ATT network. I rooted and debloated and I am blown away how smooth this runs with fantastic battery life.

I feel your pain. I was in the same situation, spending days to find a solution to these battery drain while stuck on this buggy version. And I tried everything...basic battery saving related stuff, disabling pretty much everything on the phone, monitoring everything, even changing the battery.
For now, the only thing that fix the problem for me was using a 3rd party app to force the phone to connect to none LTE network. I don't know where the bug lies: android, samsung or att side? or maybe it is because I'm out of US on another carrier who is using other freq but it is a shame. I don't think there will ever be a fix for that unfortunatly...
