[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] gooberdude:
Do a search about battery.. there are a dozen threads in the Q&A thread.

I am a minimalist and don't like any so claimed Battery Booster, Battery Enhancer, or Battery Calibrator apps that are all over the google play apps site. Most of the time I leave power saver on, and have most all sync settings and apps set to automatically update and poll info and retrieve email. As I do not like to jump through hoops to get some thing to operate as expected.

Security 360 does a great job with antivirus and memory consumption with apps. You may think that you may not need an Antivirus, but this one thoroughly checks apps if you decide to turn off Google's app checking, or use private party apps from forums or developers linking them to sites.

I use Xposed framework, mainly because of the ability to turn off functions without needing to install a custom ROM. I have been there done that and am not impressed with custom ROM of any type, over stock.

Turning off DVFS, thumbnail cache, and leaving Boost Mode alone as it is defaulted off... Is my primary setting with Winam Xposed module.

I use the app Greenify, Substrate, and its experimental plugin to Xposed. It has some nice features to complement Security 360.

Since Google has corrected some issues with some of its apps, and a few other apps have updated recently. I get 2% drain with 12 hours of standby.

Also under normal use, I get 8 to 9% drain per hour, and 6% per hour browsing.

For speed improvements, I have a 633X SD card that has been tested around 93MB/S and 44MB/s write on my laptop, there are some rated double but are about less in real life performance.

I use TweaksterMod Pro from my past custom ROM experiences, only to boost read a head cache to double the default. This only helps with super fast SD cards, the slower the SD card or having congested internal RAM the boost must be greatly increased.

With online video and media, I get about 12% per hour drain doing both streaming and miracasting to tv.

GT-N5110 & GT-N5120 - 64GB 633x on board, Status Official on SafeRooted OEM ROMs with Wanam Xposed and RootCloak. The only way to fly 8+ hours!

This badboy don't play with Play & Triangle away!

update to 4.4.2 and battery calibrate resulted in 30hr+ battery life

good to read from you andr0id23 and gooberdude. I'm a little sensitive from my battery. since I bought two n5100 for me and my sister,I compare them in many aspects like performance,physical keys (volume,home,..) quality,battery life,... first I thought there's a problem with my battery.I used to test a lot of apps (some you mentioned,battery doctor,task killer,clean master,..) on my 4.1.2 stock ROM.the result was disappointing. my note hardly lasted for 8 hours with normal use (browsing,email checking,no games).it was better on my sister's tablet.

so I updated to 4.4.2 stock rom. things were like before UNTIL i did a battery calibrate.using a method almost like this link.by deleting battery stats after full charge.

I've attached the result.

notice that i have done a full wipe before update and i don't have that tones of app from 4.1.2.only the stock bloatwares and 25 harmless apps and games.this is the best result.the battery was so stubborn to live on its last 3 percent. approximately 3 hours on 1 present and the turned off.

misunderstanding some terms

gooberdude you made it nice but I just didn't get some of these thing you said.would you please explain more?

which modules did you used and what is DVFS,boost mode

what is substrate

can you link me to the safe rooting note 8 OP please?why dont u use google play and triangle away.

sorry for lots of question.I googled them before asking but I gained not a good result.some leaded to good result like RootCloak.

thanks in advance.
[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] gooberdude:
OK, if you rooted...

I recommend getting Xposed Framework installed, then install Wanam Exposed. It has a ton of mods to adjust about anything. Though depending on model and firmware, some stuff wont work.

If you want minimal... you can get Wanam Disable DVFS... Samsung's Touchwiz has a feature to assist with games called Dynamic Voltage File System. It seems to be the root of the evil with samsung devices. Google has made it clear that battery calibration tools don't do anything to calibrate the battery. By clearing the battery stats file, all you are doing is a temporary patch. DVFS does not play well with Androids battery stats, and corrupts the data for stats, thus giving bad battery status. Once DVFS is disabled, android will properly calibrate the status of the battery. It may take a few charge cycles or manual deletion of the battery stats file and a reboot.

Again if you root, you may want to add RootCloak to allow apps from detecting root. It does it automatically once you select the troubled app. It requires Substrate and allows you to click on a link to install. Once substrate is installed it will allow rootcloak to function properly

Saferoot.zip search for it in the note 8.0 threads... I placed my copy as a file in one of the requests.

It will allow a proper root without having to flash. So no need for triangle away unless you plan on a custom ROM.

If you use saferoot, you can always upgrade to 4.4.x at a later time without having to unroot or do any trickery.

Play is messed up... never worked right on my tablet, both with stock ROM or custom ROMs

Play music does not like a large amount of media on SD storage, let alone full Mp3tags... can't handle the data or just too many files.Also music does not stop when you reboot. after some time it starts up and plays again. Gallery is messed up with image caching. So I used Wanam to disable scroll cache. I use Nokia Music Player as it is the most robust player that is small and works well on a tablet.

Freezing google music will keep battery consumption down if you have a lot of media. as I have over 4,000 files and if any one of them has an odd character in the name, the media server goes ape and cycles a lot of CPU time into trying to index. Thus sucking power like it is cheap gas.

My sig shows what a stock ROM is capable with just a few add on apps to help get things sorted out with battery power. Right now I am in a fight with Security 360... they boogered up the app with Soccer Ads in splash screens during boot and starting the app. Other wise it is an excellent app for what it does. I use it to clean out krapp that usually is not monitored by other cleaning apps, and to tweak boot blocking apps and apps that are running in background after wake up.

Greenify works fine but you may find security 360 an added app cleaner for sleep / wakeup cycles.

[Galaxy S III Mini Q&A, Help & Troubleshooting] rodaven:
Hi guys, my girlfriend owns a i8190L and she really misses the led light that had her old blackberry, so I want to make work backligth notifications on her phone. Also, the battery life on her phone sucks and it's really slow, but she doesn't want to use a custom ROM. Which kernel that supports BLN do you recomend me? It has to work on a i8190L with stock ROM. By the way, will this work with whatsapp or facebook notifications? That is almost all my GF uses.

Thanks in advance. :)

Use this kernel, is for stock & in the description says, "Support for BLN (Backlight Notifications - Ready to use BLN Control)". Have fun.

So... I'm pretty ashamed of posting this, but I am desperate as well. I flashed to stock in order to install CM11 on my Nexus 5 (had to, i don't know why it wouldn't like my bootloader otherwise) but, of course, it deleted my media partition as well.

Is there something I can do to retrieve my backups on /media? I think I can't, but I'd like a final word from someone who's not dumb as me. Thanks.

[Nexus 5 Q&A, Help & Troubleshooting] Lorthirk:
I don't think there's anything that can be done. It hurts my nerves so much because it seems I did EVERYTHING wrong: backupping only on SD and not on the cloud, wiping system from TWRP (there was no need of doing this, wiping data would have been perfectly fine), realized that the stock flash would have wiped internal memory as well while it was running but the critical point was not reached yet and didn't have the courage to stop the process before the damage was actually done. I lost a lot of SMS I was really attached to... but I hope I learnt some lessons...
[Nexus 5 Q&A, Help & Troubleshooting] teh roxxorz:
Hate to be cut and dry, but there's nothing you can do; it's unfortunately gone. When I flash a new rom, I wipe everything except internal storage. If you're flashing an update of your current rom, you need to do cache | dalvik only. Though I prefer to always do clean installs.

Any help would be greatly appreciated. Thanks!

What flavor of Android does the bank app require? Got a back up to revert back? Perhaps the update is now detecting root; most Bank app dislike having root access...anything in the change log of the bank app? Try flashing a the latest version of gapps...

[AT&T Samsung Galaxy Note II] DeMiNe0:
Hey guys. I have an AT&T Samsung Note II. I decided it was time to try a new rom and decided to upgrade from Beanstalk on 4.3 to Liquidsmooth on 4.4. I also wanted to give F2FS a shot. I flashed all of the F2FS conversion zip's, the rom, I then flashed AGNi kernel. I booted into Android, then back into recovery to install gapps.

The flash and everything went fine. I was able to restore my titanium backups on the phone and use it for about an hour. I went to bed and woke up in the morning to a Android UI Force Close that wouldn't stop; even after a factory reset. I decided to try flashing the Rom one last time, thinking it may have been a bad flash. After I flashed the rom the second time, the phone rebooted, but kept bootlooping at the LiquidRom boot animation.

When I went back into recovery I noticed an error like this in the console:

E: unable to mount /data no crypto footer

I could not get /data to mount for the life of me.

I also noticed that I wasn't able to format or wipe /data. Additionally, I couldn't flash anything to /data, and I couldn't nandroid anything to /data. I was stuck.

I used Odin to wipe the Nand and repartition the phone using a Pit file I found on xda specifically for the ATT Note II. I also restored the original stock Samsung Rom (KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar.md5). The phone boots now, but it won't get any signal. When I click the mobile networks menu it tells me that I need to put a sim into the phone.

I've gone back into TWRP and it appears to allow me to write to /data. I tried restoring a nandroid of my last working phone state, but it only bootloops even after a factory reset and cache wipe. I've also restored just the boot, efs and modem with no luck there either.

Anyone know where I should start to troubleshoot this? I'm starting to run out of idea's. As much as I want a new phone, I was really hoping to wait until the LG G3 came out before I ditched this one, but it's looking like I may need to settle on a different phone if I can't get this one working :(
[AT&T Samsung Galaxy Note II] TOA Duck:
You didn't wipe your efs folder did you. Sounds like you may have. Check for your imei number in about phone.
[AT&T Samsung Galaxy Note II] gregsarg:
I'm concerned about the "Nand erase" that was performed. ...followed by the Odin full restore. ..

I ask the same question. ..

Is your EFS Folder empty ???....g
[AT&T Samsung Galaxy Note II] DeMiNe0:
IMEI is Unknown and the /efs folder is empty.

I have a nandroid backup with my EFS in it. Can I restore it from that somehow? I tried restoring it with TWRP. and I could see the contents in the file manager in TWRP but when I reboot into the rom, the folder is empty. It's weird.
[AT&T Samsung Galaxy Note II] gregsarg:
Possibly. ..but you should first copy that EFS to PC. ...for safety. .(copy the whole nandroid backup)...

Then restore the device again through Odin back to an ATT stock rom...

This will organize the partitions again. ..

Then factory reset the new rom...

After that. ..try the nandroid restore again. ..

The phone is messed up right now. ..and needs some fixing...

Use the rom from the link I posted so you'll get the right radio image and APN. ..

If this fails...we'll try Kies and a full restore followed by a re-root and then a restore later. ..

Start with the rom I linked. ..but be sure to wipe data and caches in recovery both before and after the flash. ..

Post back here after and I'll watch the thread....g

[AT&T Samsung Galaxy Note II] DeMiNe0:
Thanks for the help! I made a backup of my nandroid and I also extracted the /efs folder out of it so I have the actual files now too.

I went and restored Zen Arcades Mk6 Rom and did a factory reset (Both before and after the flash in odin using the stock recovery). The rom boots, but I still have no imei and a blank /efs folder. I did not use a pit file or the included bootloader (I'm not on the locked mk6 bootloader).

I'm going to download Kies and give that a shot using the method documented here:

http://xdaforums.com/showthread.php?t=2261153

I've never used Kies to flash my phone before, but I know how it works to a degree. My question about Kies is; does it give you the choice of which firmware to flash with? If it forces me to use Mk6, how can I ensure that it doesn't give me the locked bootloader with knox and all that?
[AT&T Samsung Galaxy Note II] DeMiNe0:
I tried with kies, and I can't even manage to get kies to connect to it when it's in Download mode. I've tried both versions of kies, v1 and v3. I also tried downgrading back down to 4.1.1 via odin, and it's still not recognizing.
[AT&T Samsung Galaxy Note II] Zen Arcade:
Regarding your Nandroid backup:

- what rom were you running when this was taken (including Android version).

- what recovery did you use, and (if you remember) what version?

Since you have the backup on your PC there should be a log file associated with the backup that may contain some or all of this information. This may help with getting your /efs partition back.

I'm thinking copy the efs tar file from the nandroid to /data/local and then run the appropriate tar command against it to restore it. Probably best to do this from the same rom or at least AOS version from which the backup was taken - that's why the questions.
[AT&T Samsung Galaxy Note II] Bajanman:
If I'm not mistaken when I used that kies method. I don't recall putting the phone into download mode. I just plugged it into the laptop. Then started the kies program, it'll know if the phone is connected when it gets to that step!!

Just my 2¢®™
[AT&T Samsung Galaxy Note II] DeMiNe0:
I was on Beanstalk Android 4.3.1 when I took the backup. I can't remember the exact build number though. I don't have the zip file anymore that I used to flash it and I've been having a hard time finding any Beanstalk rom downloads before 4.4. I think they may have taken all of the 4.3 downloads down.

I used TWRP to back it up.

Starting TWRP 2.6.3.1 on Sun May 4 17:04:44 2014

I also attached the recovery log to this post in case there was anything else you wanted to look at in it. I saw one line in it that was kind of alarming:

I:Mount: Unable to find partition for path '/data'

but I looked further down and saw that the data partition mounted and backed up, and I see several data partition images of reasonable size in the folder.
[AT&T Samsung Galaxy Note II] DeMiNe0:
Correct me if I'm wrong, but I believe in order to use the EFR feature of kies, I think your phone may need to be in download mode. When I was running the 4.3 firmware that I odined to the phone, Kies 3(not the old kies) would recognize the phone if it was booted into android. On 4.1.1 that I odined (the original stock firmware) neither version of kies could connect to the phone.

I'm going to do a bit more testing with the different versions of kies and different stock images to see if I can get EFR working.
[AT&T Samsung Galaxy Note II] Bajanman:
That's how I remember doing it on my TMO GN2...[emoji52][emoji50]

But that's been awhile since I did that, think that was back when 4.3 first got leaked...

Mine wasn't doing anything because of something I did. I plugged it into my laptop entered the info needed. Proceed to the next step, kies starting downloading the firmware. After it's done it'll reboot the phone and start the firmware flash...
[AT&T Samsung Galaxy Note II] Zen Arcade:
Try this:

Copy the efs tar file to your phone. You can put it in /sdcard or /data/local.

Assuming it's called efs.tar and is in /sdcard then do the following (if file or location are different make the appropriate changes in step 3):

1 - install android terminal emulator (TE)

2 - make sure your current rom has busybox and is rooted

3 - then open TE and do this:

su

cd /

tar xvf /sdcard/efs.tar

When done check to see if you now have files in /efs. If so, reboot and see if you now have imei and service.
[AT&T Samsung Galaxy Note II] DeMiNe0:
I gave that a try last night. I untared everything into the /efs folder and did a fix permissions for good measure(I don't even think that script touches /efs honestly :-/). No imei still.
[AT&T Samsung Galaxy Note II] Zen Arcade:
After running the tar xvf command did you see files show up in /efs? ...Using a file manager like root explorer or similar. (You should also have seen activity generated by the tar command while it was working)
