Went thru 3 (Three) batteries tonight

Went to Bears game .Took 3 batteries with me all full at 4PM. Was using a Sprint MiFi hotspot .
its now 10PM...all batteries are dead.
Paranoid Android CM's latest which sucks as it is in the battery dept
This thing monumentally sucks...battery. More evident now thsn ever in light of my Nexus 7...which rocks.
My Note 2 will be returned on day 14 if this isn't straightened out.

Hahahaha..... go get a $15 phone from wal mart....battery life is great on those

The note is not the problem it's your rom. Try a Samsung based custom rom and you'll get better results. I'm getting 4h-5h screen on time with rocket rom and speedmod kernel (using one battery )

1. Buy / prepare more battery. three batteries for 6 hours, means for 12 hours you will need 6 batteries.
2. Buy $15 phone at walmart as suggested by alewis2k12, so you will have spare phone if the note goes dead. :victory:
3. Try other ROM + Kernel, to find the most suitable to your device.

I have everything updating at minimum times and BT.GPS Wifi and data on all the time and don't go through a battery in a waking day. I went through one and a half on a flight from SC to LA Using the phone the whole way for internet access and a movie.
Im thinking the OP needs to switch ROMS or buy a Nokia 6126 which lasts about a week

No..all Samsung batteries.
Screen was biggest user....and brightness was set at 20%.
Governor was 'powersaver'!
Data usage/battery drain is huge at events like that where tower usage is saturated and your taking pictures and sending etc.
I knew that...but this drain was unreal.
Granted, its an exaggerated example of how poor battery life is on this device...but a viable example nonetheless.
The Note's battery life sucks.
The Nexus 7....bigger screen, also rooted with same custom Rom puts it to shame.
Wise up to it Sammy.

good point, however powersavor governator is not a powersaver lol, but as you mentioned not main cause.

1. Not Samsung's fault. You're on a ROM that Samsung cannot be held directly responsible for.
2. Nexus 7 is a Device with a different spec, for valid Comparison use another GT-N7000.
3. Go Stock and Report Again - Use the Original Battery.
If you're building case remember to make sure you're under Samsung's Terms of usage. I hope you all remember about the phone that blew up and user brought it up to the media's attention, and later on it was discovered that it was the user's fault (As he was trying to heat a soaked phone from an Oven).
If you're looking for help or assistance, Then I suggest you take it to the Paranoid Android Thread. I'm sure, there are users besides the General Audience that can help you out or users that may share the same issue that you have faced.
Just my N7000 cents.

Well, tablets have considerably larger batteries than smartphones, so that's not really fair.
Also, It's probably safe to assume you aren't running the same apps on either, so apps could easily be blamed.
Instagram, for example, has been known to be a battery drainer unless killed.
As others posted, I also get all day, in general, using PA - although you didn't post which version.
If you have screen display set that low, and your screen time is still the largest (what % is that, by the way? largest could still be just say, '30%'),
then I'd put your batteries under suspect. Some of the knockoffs have very little charge, regardless of what they advertise.

What is the capacity of the Nexus 7 battery?
Sent from my GT-N7000 using Tapatalk 2

nexus 7 doesn't have 3g, turn airplane mode on the note, and battery life will double as well. Also, if you're on paranoid 0.5 and not jb, try AniDroid 0.8 kernel, you'd be surprised how your battery life improves

yeah.
I think you should bring up this issue on the Paranoid Android forums.
They sure can help you regarding this battery life issue, especially the developer, coz he will know the tweaks and changes he made on his ROM.
Rather than you blame on the device, which at the end, sammie won't held any responsible for using a custom ROM.

It has been observed that the MediaScanner is taking most of the battery in ParanoidAndroid Roms. Try stopping that.
Also you can replace the kernel and use Asylum insanity kernel to get better battery life.

Seeder entropy generator to provide significant lag reduction

I found this in Android Software and Hacking General selection (all credits to Lambgx02)
Lambgx02: "So, I was experiencing significant lag as we all do from time to time, and decided I was going to get to the bottom of it.
After tracing and debugging for hours, I discovered the source of 90% of Android's lag. In a word, entropy (or lack thereof).
Google's JVM, like Sun's, reads from /dev/random. For all random data. Yes, the /dev/random that uses a very limited entropy pool.
Random data is used for all kinds of stuff.. UUID generation, session keys, SSL.. when we run out of entropy, the process blocks. That manifests itself as lag. The process cannot continue until the kernel generates more high quality random data.
So, I cross-compiled rngd, and used it to feed /dev/urandom into /dev/random at 1 second intervals.
Result? I have never used an Android device this fast.
It is literally five times faster in many cases. Chrome, maps, and other heavy applications load in about 1/2 a second, and map tiles populate as fast as I can scroll. Task switching is instantaneous. You know how sometimes when you hit the home button, it takes 5-10 seconds for the home screen to repopulate? Yeah. Blocking on read of /dev/random. Problem solved. But don't take my word for it .. give it a shot!
Update!
I've built a very simple Android app that bundles the binary, and starts/stops the service (on boot if selected). I'll be adding more instrumentation, but for now, give it a shot! This APK does not modify /system in any way, so should be perfectly safe.
This is my first userspace Android app, so bear with me!
Note that this APK is actually compatible with all Android versions, and all (armel) devices. It's not at all specific to the Captivate Glide.
Caveats
There is a (theoretical) security risk, in that seeding /dev/random with /dev/urandom decreases the quality of the random data. In practice, the odds of this being cryptographically exploited are far lower than the odds of someone attacking the OS itself (a much simpler challenge).
This may adversely affect battery life, since it wakes every second. It does not hold a wakelock, so it shouldn't have a big impact, but let me know if you think it's causing problems. I can add a blocking read to the code so that it only executes while the screen is on. On the other hand, many of us attribute lag to lacking CPU power. Since this hack eliminates almost all lag, there is less of a need to overclock, potentially reducing battery consumption."
atomic339:
Download from here
Flash in recovery...it installs an init.d script to launch at boot, rngd and entropy_watch binaries amd also am extended menu by me....after flashing, just go into terminal and type:
-su (enter)
-seeder (enter)
(The apk from OP does not work for every phone, but this init.d method will work as long as your phone supports init.d...)
My opinion:
-my gallery pictures loading "instantly". wtf!
-browser loading faster
-Maps loading much faster
-settings menu scrolling smoothly.

Working great here

Im sorry this is not for you if you worry about warranty.

Umm.. i can't found anu differences after flashing the zip file.. maybe there is something i should do after i type seeder on terminal mate? And where is the apk?

if you do it the APK way make sure to exit the app using the home button not the back button because pressing back will turn it off

So is this basically just holding a partial wakelock forever and therefore increasing performance and killing battery life? Do we really know what's being accomplished here?

Everything I have seen indicates that the smoothness is coming from the CPU being held out of sleep. My "proof" is a user of the original Note saying it fixed his home button wake lag. That ONLY disappears when the phone ain't sleeping...
I don't think there are any major performance gains to be had from the ACTUAL fix, maybe as a side effect of holding the CPU up - but you can adjust the governor to do that.

That's a pretty ridiculous solution.
Create a symbolic link for /dev/random pointing to /dev/urandom. Done.

So, as some one earlier said, this is just keeping our phones awake all the time right?
If so, thats bad, isnt it ?

exactly. just trading battery life for less stutter. or in our case, just killing our own batteries since the gn2 has pretty much no stutter anyways.

http://forum.xda-developers.com/showpost.php?p=36274506&postcount=1014
Hmmm so it is almost same as lowering cpu up threshold. Hmmm for low end phones ofc there will be performance boost for note 2 no difference while we have good software+hardware

so i test it my self and i don't see any difference :silly::silly:
edit : dose the app need init.d support ?? i'm testing with stock kernel :banghead:

Anyone tried "Lagfix" that enables Trim for LG G2?

Guys,
Anyone tried this app on LG G2 D802?
https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&hl=en
This enables TRIM that supposed to come with Android 4.3 update and should help with Lag issues.
Some one tried?
can it harm the device?
Thanks!

I have bought the premium of this long ago, for my old/other devices.
Please read up on which kind of LAG it should help.
LG G2 is not lagging or rather when its lagging, its due to the throttling or something else.
TRIM won't help. Won't do anything for you. Kinda would like that the placebo effect goes away which some ppl experience on other devices. Not saying it might not help. But mostly it's really just placebo. Lets say 1 in 100 000 specific devices under specific circumstances it helps... and not LG G2 .
(Not yet)
Android is out for more years, lets say after 5 they introduce TRIM and now every device and every one needs it? Wanna tell me that every device was lagging the past years? < @op This was not for you, but for the defenders that will pop out saying that TRIM is the almighty savior of high end devices.
You do not need TRIM. (Again not yet)

I used it on my Nexus 7, prior to 4.3. Works good on some devices that have poor i/o over time. I doubt it makes a difference on the G2, we'll most likely have a 4.3 or higher rom with built in trim before you would see any issues with i/o lag.

I must say. Installed lagfix on g2, everything being indeed smoother and seems as much less sttutering and scroll lags.

well the fixes you seek are not really there, android itself laggs due to the way it is designed.

From my understanding of trim , you should still see a performance gain no matter what. This gain becomes more apparent as you use and fill your a device.

Are you referring to the lag and stuttering issue? I don't understand how trim wouldn't help a heavily used G2 on maintaining IO performance over time.

What I said and meant is that in 99 % cases TRIM is only a placebo.
And in case of LG G2 it's 99.99999% placebo.
Look 5 years phones were fine without TRIM. Now suddenly it's a magic cure?( For a problem that 99% of devices didn't have?)
Even Google knows it's not like that at all. If it was, don't worry there would be more advertising behind it.
Stop reading into the technical details of it. As I said not my first device. Bought the premium one long ago.
Real life usage different from paper.
When you could see some benefits of TRIM on LG G2 we will have Android 5.5

App requires a root, is there anything else we can try that does not require a root? If all else fail I will exchange the phone and I don't want to run into problem with a rooted device.

it's definitely faster. see the screenshots, the later one is obviously after applying the fix
running on rooted stock 4.2 on D802.

Battery drain, Bluetooth, help

Hello everyone , my AT&T LgG2 is running 4.4.2 and my battery life has been pretty poor. Blue tooth is always on even though the switch is off . I tried a factory reset 2 times and it wouldn't change. Also my battery is drain much faster that on 4.4.2. I can't run any wakelock detectors because I can't root my device and frankly don't understand Most of this rooting stuff.
I installed greenify but that app is limited due to non root mode . any suggestions would be greatly appreciated. I've also noticed that my ram is always above 1 gig. And I normally have about 500-600 free. This seems excessively high. I've tried using task killers and they say they have freed 100-300,MB but a few moments later the same thing happens .

i am using even modify stock rom without bloatware

I've just upgrade to 4.4.2 today, and I have same problem with bluetooth. But on mine, it dont eat battery too much like you. On my phone, when I turned off bluetooth, it still use 7% battery. I am very curious about the reason of this, too.

Few thread about are saying this isn't an actual drain but a miss read of stats because of kitkat.
Sent from my LG-D802 using xda app-developers app

Bluetooth isn't actually on; it's a bug in the stats reader. It doesn't cause actual drain.
For me, battery is better on KK. If you have extra drain, I don't think it's because of the update.
Furthermore, your RAM usage seems normal. Modern OSes cache certain things into RAM to make things go faster. That's what RAM is for. Less used RAM != faster phone. It will automatically clear up cache to make room for other apps as needed. This is why I do not recommend task killers.

If its not actually on why does the stat always change like its been running.? Also as for the ram it starts hitting 500 and the phone star s to crawl. Its not killing things on its own. It just seems odd that the is is using a gigs worth of ram when I have nothing I use on. At least with a rood I could freeze all the bloat.
I'm waiting for a simple root because when I start reading the ones available I get all lost in this tool that tool this firmware that blah

Any fixes? Bluetooth i s going crazy after KitKat update on my G2 too! Seriously, battery has gone from awesome to 'just good'.comparing to bluetooth, WiFi battery usage is negligible (low 0-1%)

[Got what i needed..thanks!]Looking for a helper for about a half hour.

Used to have a one plus one. I jump phones so I left. Hey...its what I do. What I am hoping for is to prove a point on why my one plus one got way better battery life then my G3 does. Virtually the same specs. Same carrier...same apps. Now. Here is where someone with a 1+1 comes in. Using this app https://play.google.com/store/apps/details?id=com.iattilagy.usemon you can monitor the GPU usage if you scroll down a bit. Would prefer a relatively stock like setup. It doesn't even require root. Just run this app for about a half hour using no games or anything just oh idk. Texting, hangouts, Tapatalk, no gaming. I want to see what the GPU freq it runs at most often in that 30 min. Then snap a screen shot and PM or post it here.
Hopefully someone will help me out with this.

I can probably do it for you sometime after tomorrow, I'm currently running AK's kernel so I can't do it atm. Whenever I flash the next nighly I'll wait on flashing AK's kernel, and then I can do it for you as I don't use my phone too much during the week, if no one else has done it by Monday just PM me, and I'll do it for you.
Also, any particular reason you jumped to the G3?
EDIT: I run a very stock setup , running CM12 nightlies. No background apps like skype or whatever, either. Should be perfect for a comparison.

Perfect! Not really any particular reason besides same specs and slightly smaller bezel. Never figured the difference would be night and day. 1+1 wins in my book.
G3 battery life is horrid imho. I got 7-8hrs screen on almost daily. With he g3 only about 3 give or take. Got a 9000 mah battery now. Things a brick but I get 11-12 hrs screen on. Its sad. With this battery and my old 1+1 I'd feel comfortable in saying 20hrs screen on min probably 24

Yep the GPUs are working about the same. Has to be the screen it self that makes it such a hog whether it be the QHD since they both IPS displays.
