[Q] Nexus 7 zigzag-like battery graph - Nexus 7 (2013) Q&A

I have been using my Nexus 7 2013 for few months and the battery is really strange.
The battery graph is often zigzag-like as attached and I really don't know where the issue is.
I have been using purity rom, franco kernel with smart cover.
I am also charging my Nexus 7 2013 with my Nexus 4 charger and external powerbank.
Is this a battery problem and should I get it back to ASUS for warranty?
Thanks everyone

If it hasent been doing this long i would give it a week or two and if its still doing it, then i would be concerned. But i also think that some custom kernels may also have this side effect, i dont know why, maybe someone more with more knowledge of kernels could clear this up. Atleast. I hope... Mine does this aswell, but i dont stay on the same rom for more than a week or two ?

I am not sure why this happen and my first thought is battery issue.
I am lazy to try out different roms and kernels unless this issue persists.

Id go through a few full cycles, it does this to me on glitch kernel, but i tryed stock rooted rom the other day and noticed it wasnt happening anymore.
Edit: just looked at the graph again. Looks like you werent even using the tablet at all. If thats the case then im afraid this might be bad. Sorry friend.
But i wouldnt get too worried just yet, give it a few days, if it doesnt settle down or stock does the same then id think about a warranty.

Thanks very much and I may observe it for another week.

I have the exact same issue with my Nexus7. Rooted stockrom and it is zigzaging also. But batterylife is still very good, now its been up 2days and 12 hours with screen time over 5 hours. So im not going to send my own into warranty just yet, because every other common known problem is not on my device

I have stock rom , not rooted and I get the zig zag battery also. No problem tho, I am very happy with the battery life .

New GN froze had to pull battery...No big deal?

Hi everyone,
New GN,
ITLF41
19250UGKL1
yakjuux
4.01
I've only unlocked it, haven't done anything else.
I was only replying to a text message and in the middle of text, GN froze and the screen went black with a white line across top of screen.
Seemed to occur while the auto-rotate function was trying to rotate screen.
I also noticed the auto rotate on my GN does not work well at all. Sometimes it does, sometimes it will not no matter how long I wait.
Nothing worked, had to pull battery.
Seems fine after replacing battery.
I wouldn't be concerned but for the fact that I was not using 3rd party apps or a different rom. The force 2d option is off.
Is maybe something funky with the GN auto-rotate feature in 4.01?

Yes, versions 4.0.2 and 4.0.3 fix a LOT of little issues with the GN. They really should've released the phone with one of those 2 versions rather than 4.0.1.
I don't think you should be too worried about battery pulls unless they happen more often than you like.
Just like a computer...rebooting or pulling the battery at least once a week is recommended!

I'm a Network Admin for a large School Board. I know its strange I know nothing about smart Phones but I do know much about Wireless/Routers/switches and Computers.
If your rebooting computers once a week something is amiss....lol
I have servers and clients that have uptimes of 1 year+ before an update requires me to down a server or re-image a client.
In my case, if what had happened to my NEW GN happened on one of my OES2 Linux servers, Id be scrambling until the issue was found and fixed and i'd be none to happy.
But alas, a server is not a cell phone.
I hope it was a just a freak isolated incident.
You guys...I wasn't saying that u HAD to...if u HAVE to, then there's problems....but if u do it just because, it'll get rid of the little things, like the bug he has

One very simple reason: If you pull the battery in a bad moment, e.g. right when the hardware is writing something to the Flash memory, you might (soft-) brick your phone and lose all the data on it.

Well because,
If I have to keep pulling the battery (which is NOT occurring thankfully so far) then I would say something is wrong and its not just a software bug. I would call it a blue screen of death in computer terms.
That could be anything from a hardware fault (Memory/CPU/IO sub system..etc) That would for me, mean taking it back.
A hard reset may temporarily fix the issue. But it doesn't solve the underlying problems.
I'm hoping the error was a one off. If it never occurs again, then we're good to go.
If it does, its goin back.
Same thing happened to me, the weird thing is it happened right after I completely reset the phone...

Yea its strange...
In my case the Auto rotate feature seems to be the common theme for funkyness.
Sometimes its quick, less than a second, sometimes it doesn't move at all.....
Then, a hard lock.
I realize that 4.02 and .03 fix some bugs but I have the Canadian ver. and google is not gonna update OTA for my NG.
I'm not ready for the whole, flash to "google's" stock rom yet. I just learned to unlock it...lol. If it locks again i'll try that. If it don't i'll leave well enough alone.
Oh by the way, to the Admins, sorry for not posting in the Q&A section. I though i was in the Q&A, my mistake.
Please by all means move the thread.

Actually, I have to replace cmos batteries all the time.
Usually they are good for 4 or 5 years but sometimes not.
Some people don't know what "Hit F1 to continue" means and I get calls all the time.
So yes, its quite common to have to pull a bad battery when dealing with 2,000+ PC's ...

Because I use a otterbox with my Galaxy Nexus and it's not very pleasent to keep taking my phone out of it's hard shell case and putting it back in?
Pulling the battery is always a last resort. If the phone is frozen, that is fine to pull the battery or you can hold power on the phone and it'll turn off by itself (not sure if this is in the GN but it was in Galaxy S1).
@test4echo: That's not the experience of a daily person. Not everyone deals with 2,000+ people on computers.

You are correct. Its not a common everyday thing for most.
I was just suggesting a legit reason for why anyone would need to pull a computer battery.
On another note, i agree with you that having an otterbox case makes it even more of a pain to have to pull the battery.
I just had another freeze up while trying to get back to the main page using the launcher.
Im getting worried now. I've had this phone for 2 weeks and it was great until today....
I think I'm gonna bring it back to virgin just to be safe before my 30 days is up.
If its just software then the new one will do it as well but at at least I'll know thats what it is and either wait for samsung updates or update manually.
Again....nowhere in my response did I say u HAVE to pull the battery every week....I simply said its best if u do, nobody is gonna force u to! But when u do get a bug...pull that battery, and if it keeps happening, send it for warranty...simple

got back to stock ROM

I rooted my phone about half a year ago, and now, finally I got back to the stock ROM. You may ask why, so here is why I initially rooted it, and then why I got back to the stock ROM.
My main reason for rooting was the extremly small sized internal storage. Even with the "stock" app2sd it was hell like fast full. Of course customizen played also a role, and I liked the ability to change like everything the way I like, but moving nearly the whole apps was the main reason.
So I finally decided to root my phone. The process was (in opposite of what I thought) really easy, especially with the help of this awesome guide and I chose "MIUI" as the first OS to try out. I really liked it, but I had some occasional crashes which I wasn't able to solve. But that wasn't the reason I got back to the stock ROM. After about 2-3 months with "MIUI" my complete phone got stock in a bootloop. Flashing the zip again wasn't succesfull, so I finally tried an older backup. This worked, but sadly all my SMS data and else got lost.
After some searching I tried out cyanogenMod. I liked it quite well, but I also got the crashes and freezes I got with MIUI, but I was able to live with it. But then, about a week ago, my phone got completly stuck in a bootloop, and instead of throwing it straight ahead into a wall, I flashed back to the stock ROM.
At first I was quite surprised how fluidly it runs, in comparision to cyanogenMod. Then I noticed, that you can't really switch between 3G and 2G data, and was afraid of getting out of energy much sooner. But the opposite happened, the battery lasts much longer than with the other two ROMs, and I hadn't had any crashes or complete freezes till yet. Also, I haven't got the great warning "Battery level 0% or lower (how is this even f*ing possible?), please connect to power source" I got on cyanogenMod, with the addition of my phone shutting down immediately afterwards.
So, long story, short: I really like the ability to root my phone and everything, and I do not regret having done it. It was a great experience, I now I know the "true" capability of android. But after all this trying out, I have to say, that I think I will now stick with the stock ROM, since it's more stable. Probably it was a hardware issue with my device, probably some kind of software bug. Maybe something of both.
just my quick thoughts, and sorry for my bad english, but it's not my native language
To each his own.
I've been using Cyanogenmod more often than any other rom and never experienced bootloops that is caused by the rom itself. It's always something I did with the rom. LOL
Well, that's also a possibility, but since I wasn't able to find the cause of it, I gave up. It was not only the bootloop, but also the quick battery draining and the complete freezes.
I understand where you are coming from... You just want it to work properly.
As for the battery, the default cm7 kernel isn't really that good compared with ManU kernel. That's the first thing I change when I flash.
Now I'm taking my stopwatch to count how long will it take for loons to start Runnymede or ICS recommendations.

Long story short??
Maybe you should publish the unedited version...could be a few volumes in that.
Also, will never go back to stock. I unrooted last year, so I could set up for S-Off, and couldn't wait to get back to a custom ROM. Slow, boring, low storage and boring.
You should use Runnymede, it's the best ROM ever!
Annddd there you have it Erklat.
haha. Funny. And necessarily runnymede
You have luck with the Battery, my phone say 15% or Lower and shutdown, if yours work down to 0%

Well, that was the problem with it...the battery showed 20 percent when it happened...
btw, the stock rom didn't solve that problem either, but at least the crashes are gone...it's still pretty weird, the battery level showed like 20% or more when it suddenly shut down...
Battery life has always been dreadful on the Desire no matter what ROM you use.
Now on the bootloop, Sandvold ICS Beta 0.4.4 ROM seems to be getting on well.
No bootloops whatsoever!
(Some lags and bugs may occure, but nothing you can't handle with a little bit of patience! )

[Q] Problem with SOD? PLEASE HELP

So here's my story...
I hated the new ICS official update that sprint rolled out because of my diminishing battery life. So i decided to finally root the phone and install some roms. Everything went well for the past week but now my phone screen flickers and then my phone shuts off when i still have around 80% battery life left. I try to turn it back on and it loads up the boot screen but sometimes it fully loads the phone and sometimes it doesn't. When it does load ... my battery life is chopped to like 20% or maybe 5%. I calibrated my battery after the flash like someone told me to do but it still didn't work. I thought it was the rom i was using but I flashed 3 different roms and I still have the same problem.
I'm wondering if it's something wrong with my battery or my power on my phone? When the phone is charging it doesn't flicker and shut down on me.
Did anybody else have this problem? Is this considered a SOD? Wondering if I should get a new battery and see if it works. Also... is your battery flat? Mine seems to be a curved a bit in the middle back and front and i don't remember it being like that.
THANKS FOR THE HELP PEOPLE!!!! I really need it
Spin the battery on a flat surface and if it continues to spin, its bad. From your description of the back if battery, it sounds bad. Take it to a sprint store and get a replacement.

This is just the effects of ICS. Go to to your sprint store , they should replace it free. Consider a custom Rom to remedy the issue.

Rom version Blazer FF18
kernel version 3.0.15-sph-d710.ff18-cl663858
Baseband version FH13
I am trying to underclock the phone now and see if it solves any problems till I get a new battery. Realized that while the phone is plugged in... it doesn't flicker and shut down on me. So maybe if i lower the power consumption, it'll work. But it's just an idea I came up with.

Your experiencing a condition that's clearly battery related, while phone is plugged in it clearly shows that the problem is the battery. Making changes and undervolting may just complicate things, I would wait for a new battery before going any further.
You need a proven rom to start with, ask around and see what works for others and give yourself a fresh start. I would recommend going back to stock gingerbread el29,and trying it out for a week or so, then go from there.

Will do. Just ordered a battery. Hopefully it is a battery issue because I am not due for an upgrade yet. Thanks a lot for your advice!
It's the battery, I have the same issues right now and if I use a different battery they instantly disappear.
And you're right about lowering the power consumption, for me it only happened with 4G enabled together with the capacitive LEDs. Disabling one or the other made it go away.

Battery stats RESET at every reboot!!!!!?????

Battery stats RESET at every reboot. Is it just me or is this a JB/Samsung related bug? To me this is NOT normal and it definitely didn't happen in ICS or GB
------------------------------------------------------------------------
:good: Updated Tue, Nov.20.2012
As strange as it may sound, after about 3-4 cycles, the funny issue reported above is gone. Now my SGH-I317M behaves like it's supposed to and so, the battery stats are being kept after reboot. Like all the other Samsung phones I have/had, the battery stats are being reset after the phone has been kept plugged in for a while - which is normal. I took some time to report this just to make sure that it's consistent.
Yeah, I find that annoying too. I wish it kept it's settings. I was hoping to get an accurate look at my daily usage today, but an early reboot is going to destroy that.

Still...I wonder, is this a bug or is it Samsung's/Google's new vision about how battery stats are supposed to be working? If it's a bug they'll probably fix it but if the bug is in someone's head, then we're kind of screwed - from this point onward (JB, KLP, etc)

Not quite sure what you mean by "stock phone" but I have the SG2 (SGH-I727R) with ICS 4.0.4, rooted and SG3 (SGH-I747M) with ICS 4.0.4, rooted and DEFINITELY none of them do that. The Note II (SGH-I317M) is certainly my first Android phone to do that - after all, think about it! Is your battery starting a new cycle after every reboot? Plus, the phone might not even get close to a plug. Why reset the stats?

Stock implies just that...STOCK. no root, stock. Dont know what to tell you but both mine did this quirk. Was annoying as hell.

I used "Device Analyzer" in the past to see a weeks worth of battery stats in one view. But it only gives you charge levels, not app usage.
My One X resets if I charge it above ~70%. Every android ROM and phone I have had in the past only reset at a full charge. And I haven't seen one yet that resets at a reboot. Sounds like a bug. Fingers crossed for fixing when they push the side by side app view update.
To make sure, we are talking about this data, right?

Poor battery life...

Hello,
The battery life of my Z1 compact is very low. This only started the last month or so.
Are there things I can do to improve it?
I have been thinking of putting another rom on it, but not used to this anymore. A few years ago I did a lot (with my HTC Hero), but at the moment I don't have time to do this regularly (read: I was single on those days ). I can remember that there was an option in the recovery to whipe the battery stats, so maybe this can help me.
Then, is there a light yet stable rom out there?
Maybe you can give me also some guides on how to start with this: rooting, replacing recovery image and flashing a custom Rom.
Anyways thanks for your help.
Sorry if I made some mistakes, English is not my native language.

This additional info can maybe useful:
Currently I am on Android 5.1.1 Build 14.6.A.0.368 ...
Most people have noticed that battery life on LP is generally a little worse than on KK, but usually stock rom battery life is pretty good, so if it's just getting worse suddenly, you might want to try an update, (.368 is not the newest fw), or maybe some changes you made are draIning the battery, or maybe the battery is old and needs to be replaced. Most custom roms are fine as far as battery drain goes, but most are not better than stock, so probably not a solution to the issue. Have you been using any battery - saving options, (stamina, Greenify, etc.)?
Are you using Pocket (readitlater)?
The new version of the app sucks alot of battery... =(

Basically, you need to replace the battery.

I have seen that there's a newer update (14.6.A.1.236). The problem with this is, when I try the update, the phone says there's no update for the phone. Is there a way to force the update?

I have been looking and found some local repair center, which can do it.
While it is still under waranty, I don't want to send it to Sony, as I expect to lose the phone for more than 3 weeks???
Anyways, big thanks for all your replies!

I found it pretty easy to replace the battery myself, but that will void the warranty so you might not want to do that if there is still significant time left to run on the warranty.

Is there some good description on how to do it yourself? Because I have no clue on how to even start with it?

I'm pretty sure there are instructions in that thread, but otherwise there are various videos such as this one:

This is how i get most juice out of this xperia. 2 years old battery shouldn't have degraded more than 10%
I should have posted this. I have found some useful info about changing the battery (mainly youtube), and I already ordered a new battery and adhesive for the back cover.
Another question I posted earlier: is there a way to force update to version .1.236
