I have problems with the battery of my nexus 7 since last week when I realized it was charging slow, after that it runs down very quickly, and tried everything that is on this forum and nothing. I put The latest franco kernel. and nothing.... is the battery damage ??
nexus 7 stock rom 4.2.2
unlocked and rooted
franco kernel r61
sorry for my bad english :silly:
THANKS
Probably, but have you tried perform factory reset?
Sound like software related problem to me, like some rouge apps running all the time and prevent your tablet from deep sleep.

Yes,did a factory reset,flashed stock rom
Hi,
I hope I made this in the right section but I've got myself into a really nasty problem and I know how to fix it after spending full 10 hours. Maybe this will help anybody.
I re-used my Arc after a while and learned about custom roms and all. I've updated to Stock 2.3.4 - Stock 4.0.4 - Ultrakitkat 2.0.1 - Stock 4.0.4 (back because of trying to compare performances between custom and stock) - Ultimate HD 5.0.1.
When going from Ultrakitkat to Stock 4.0.4, after a day I woke up and found my phone rebooting Android on a loop while in the wall-charger. Went to take a shower and the phone was dead.
Charger didn't work, put it on my laptop USB and went on, only to find the battery at 100%. When disconnecting the phone, it immediately went blank and didn't turned on. I've looked for this problem for so many hours and tried flashing my romand kernel for some time (including phone drops dead WHILE in flashing) and trying out different way's to connect and boot but nothing worked. Installed many battery tools and apps but still nothing.
I;ve searched a lot and didn't found any conclusion anywhere, but combining every information online I've solved it!!
Apperantly there is an error inbetween roms, that when you go from custom rom + certain kernels, back to stock rom, it stops recognizing the battery.
To solve this (for me it worked):
Flashtool stock TFT 4.0.4
Fastboot flash the LUPUSV16 kernel (the magic trick!)
Turn on phone, and put it on a charger for 15 minutes, it should start recharging somewhere and show the correct battery %
I wanted to use the Ultimate HD just for a try and when flashing (I use Advanced Stock Kernel) + Ultimate HD
DO NOT WIPE BATTERY STATS! This will recreate the problem.
This worked for me and I hope this will help someone too who's thinking there is a problem with the battery.
Mostly reflashing the kernel does the job

Leaving the phone turned off for some hours worked for me!
Thank you!
if you dont want see this problem
do not downgrade to stock kernel
Same issue here.. after fastbooting stock ftf.. Phone not charging and not recognized in fastboot/flashmode
Guys worked for me
Flash rush kernel after downgrading and tada its done.
Its just coz rush recognizes the hardware chip algorithm for battery stats

yes, it works flashing other kernel but i encountered a another problem. I lost some of the apps and keep geeting crashing report from diferent sistem apps Does some know how to extract those battery fix from those kernel am apllly it to stock kernel?
ok, we have a nexus, so we deserve updates and we have them....that's why we bought a nexus no?....
yes....but every update is a hit for our device's performance...I thought that last one would fix performance issues, but is not .
so...I bought one of these to my gf, sure that it would work well, I owned one a year ago and it was very good! nope....is slow, lags, remembers me a 100$ cheap tablet.
I considered to downgrade....is frustrating...what version do you remember as stunning fast, like a nexus should be?
4.1? damn, is too 2012-ish....
4.2? old but at least we have tiles on notification drawer...
4.3? good, some performance goodies, hw vsync...
4.4? I thought this would be the best choice because in theory is optimised for 512mb ram devices too....but was not performing well
5.0? don't say nothing...pff
I also read about f2fs as a revolution, but is not my tablet and my gf uses it for study and I can't take it to test...
thanks for reading and answering
My 2012 Nexus 7 (wifi) I had been on Android 4.4.4 when I updated to Android 5.0 using Wugs nexus root tool kit.
It had been sluggish on Kit Kat, but got more so when I went to Lollipop, even with a full wipe.
After about a week on 5.0 I rolled back to Android 4.3, and have been happy since.
Everyone is having different experiences and mine personally is that 5.0 is running greater for me then 4.4.4. That was with a complete full wipe (including data) when I flashed the image through wugs toolkit. There were initially bouts of lag (waking up screen, lock screen, etc) but the lags pretty much gone bar a few occasions. 5.0.1 will hopefully make the system more stable and not repeat what happened with 4.4.4 because my n7 ran like a pig after that update.

And how are you with 4.3? Perfect? I'm really considerino a downgrade....
I will try forma the last time a full wipe and factory image, and then downgrade until I'm satisfied.
No words about f2fs?
I have just updated my n7 to Slim rom 5.0.1.
I have been frustrated by not being able to read a simple email using gmail application. Lags, lags, and "gmail is not responding do you want to close it"
I need to have two accounts for me and my wife, so the performance was even more slow.
Now with f2fs it is a rocket. I have installed every toolvI wanted and now also the Godfire game, and I must admit that it was a hit.
So thank you google to slow our machines to force buying the new ones, but my nexus7 from 2012 acts lighning fast now.

I read some but guides were outdated...and, FYI I am very experienced on flashing, so I will not take you much time
Not sure if stock can be ran on f2fs.
I installed slim rom and itis close to aosp.

No, I don't have it. I just asked is there slim lollipop on f2fs, because I tried rastapop and SleamFreak which are on 5.0 and have f2fs support, but I had problems like rebooting, problem with installing new apps, etc.
So for now, till I get answer from user emmyhi, I back to slimkat KK which run fantastic on our Nexus 7.
SlimPop (f2fs) by Freak is great. very fast.

Yes, I can agree with you that is really fast, but I had a problem with gapps (downloaded one's give in thread) and I couldn't install Google play store (it wasn't installed with gapps???)
I couldn't resolve my problem with that, and also, even I did clean install I haven't got screen like I first time use this rom. I haven't got possibility to chose language, and everything else. Rom just moved me to homescreen. Maybe this is not for this thread, but, I'll wait some other version of slim on 5.0.

Did you try SlimGapps Normal one from the op link. That worked fine for me. You first flash the Rom. Boot. Go to recovery again. than flash Gapps. Boot. You will get the initialisation screen.
too much beta, I can't take my gf's tablet everytime she has a problem ahahah
I will try an evening every factory image and a kk f2fs rom to see which one performs better...then I'll let you know!
I'm running stock rooted 4.4.4 kitkat on mine with Lean Kernel 4.1. No lag, no issues with apps not working like on 5.0. Good battery life ,watched over 5 hours of movies last night and still had 49% left from a full charge. Standby time is excellent, I've only lost 2% over the last 9 hours.

that stock one with f2fs?
No, not here. Pure stock, rooted 4.4.4 KitKat. Removed a few Google apps I don't use, but still ext4. Lean Kennel really make a difference.
and....after a flashing afternoon....
4.2.2 stock was damn fast....
4.3 stock was even faster and smoother than 4.2.2
4.4 was worse......got better with lean kernel, but wasn't just fast and responsive enough.
the winner is....4.3......that's what I left on my gf's tablet....
everything runs good, apps opening instantly, look much 2013 but google launcher and google keyboard help...
this is my suggestion after my tests. good luck and hope next LP ota will fix some performance issues, not only on this one but for every phone which got slower with this update
Hello my problem start when i update to this android 5 or lollipop , now the battery life is 3 or 4 hours max ...i never flash or root my smartphone before but i know there are a lot of custom rom fast and good for battery life. My uses are web, watching videos, messaging and some apps news.
My question is what is the best ROM for good battery life and speed performance and how i can install it now in my nexus 4 with android 5.01 and without root yet. Because i cant any more for this battery in new ANDROID 5 .
THANKS
Did you try a factory reset? Imo lollipop is great. Bought back life to the N4 and my battery life is amazing AF since the update. On rom base I'm using SimpleAOSP w/Nash kernel R13

If you factory reset you'll still be on lollipop. I'd recommend SimpleAOSP, hasn't failed me. You can find that in the N4 Android Development where youll find the toolkits to toot your phone. Also in this section there's a sticky thread called Nexus 4 ultimate root guide

Please i want something good and official its IMPOSSIBLE 3 HOURS of battery A DAY ?? :|
can someone help me please because i dont arrive at 12pm, with this ANdroid 5.01 can someone give me a tutorial with how to install ROM ,
ps. i never flash or root smartphone before !
thanks
Patience is a virtue, my child. It won't kill to check out the development forum to see what's going on with CM12. Remember the Lollipop just came out and it's going to take a long time till there's going to be an official CM. Use the toolkit and root your phone and unlock the bootloader and install a custom recovery. Word of caution, backup anything important on your phone, unlocking the bootloader will wipe your phone. But that's a good thing, now you have a clean phone. You can either stay on stock rooted or use the rom which I'm using. It's called SimpleAOSP http://forum.xda-developers.com/showthread.php?t=2932090

You should have a app that makes your phone wake. The problem is not with android 4.4 or 5, it is something else.
Check if you have NFC on, wifi on (wifi searching, while wifi turn off, on), mobile data on, gps on, bluetooth on, google now on, sync on, check your apps (you can use BetteryBatteryStatus (need root) https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en), you can use Greenify to hibernate some apps (https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en).
You can also do this. Plug you phone and charge it to 100%. Use the phone until it shutdowns (when it reach 0% battery). Then, with your phone turned off, plug it again (use the wall charger) and wait until it charges to 100% and wait 30, 60 min more. Then use your phone normally.

Get rid of battery doctor and the other apps you use to delete cache and I bet your battery is better. Then get gsam or betterbatterystats and determine where your wakelocks are. Minimize those

First of all, do what jd1639 said. Get rid of those apps. You are wiping the cache, but the android automatically build the cache again. If you use app killers, it kill the battery and doesn't provide any benefit. They do more harm than good.
The android 5 is for nexus 4 too. Go to the battery settings and see what apps are consuming the most battery (if you don't want to install betterbatterystats). Post printscreens of your battery settings and the apps that consume the most battery so that we can help.
Here is a thread that helps you get root and install recovery and custom rom: http://forum.xda-developers.com/nexus-4/help/guide-ultimate-nexus-4-root-guide-t2018179
But if you backup your apps and restore them, it is possible that you will have the same problem with another ROM, since it is very probably an app that is killing your battery.
After I installed CM12 for D802. I notice that my battery run out faster than usual. Almost 10% in 15 minutes (just checking my Facebook).
I decide then to flash it back to the stock using LGFlashTool. But the same problem.
There's any one who faced this problem ?

Download and Install BetterBatteryStats.
Use your phone as normal for a day and at the end of the day check the app to see what's really using your battery the most.
If you find the application doesn't help, perhaps post in the thread asking for someone to review your logcat.
P.S Facebook is known to be a resource hog. That's why I refuse to use the app.

Thank you, I'll test it out!
i realy would love to know the cause of this an a way to fix it,
i have this issue since i started rooting my lg g2 d802 and flashing roms, even unrooting and falshing official kdz roms did not helped at all.
I'm on the phone has firmware: cm-12-20150221-NIGHTLY-ls980
And I have a problem with the disconnection of a conversation on the phone.
Accept a call, talk and then the connection is lost as if hung up. This situation has been observed for 10 consecutive assemblies. Although this was not before!
Phone model: LG G2 LS980
Modem: ZV8
Firmware: cm-12-20150221-NIGHTLY-ls980
Please tell me how to solve this problem?
I too am only getting about 14 hours of heavy use when it used to last 24+ hours on stock 4.4. (D803)
I thought it may be due to a poorly coded radio by my provider but am starting to think it may happen after update to lollipop. What radio/rom/kernel is everyone using?
I've tried the following all with similar results:
Resurrection remix 5.0.2
Resurrection kernel
RGR_10C radio
CM12 5.0.2 nightly
CM12 kernel
RGR_10C radio
I've found that the stock radio that came with both roms gave me better battery life but then the rotation never worked. Has anyone figured it out yet?
