[Q] Incoherent battery read outs - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Is there any news regarding the battery problems on the Note, I don't mean fast battery drain or something like that. I mean the malfunctional battery percentage read outs: for, example the phone shuts down, because it is out of battery and then when you plug it in, and just short press the on/off button it says the battery is charged 50% or something like that, while it obviously isn't. Also when you have just checked it with this short press on the on/off button, if you properly boot in the os it says the battery is 70% or something like that. This doesn't seem to be a app related, but more a kernel related problem. I know some other people also had this problem, but I haven't seem anyone yet with a solution...
I don't have a logcat, but since others also had this problem I don't know whether the devs needed another. I do know this could just be a bad battery, but this is my second original battery, so I don't think this is the problem.
Personally I have no problem with a bad batterylife, and with SlimKat the batterylife is wonderful, but because of this inconsistent read-outs I have no clue when the battery is charged, and it just dies on my on random moments
THE POLL IS WRONG, just state whether you have problems in the comments

[NOT] WM5 Power bug (bad battery)

<BUMP> Is there a WM5 ROM which doesn't exibit the “dies @ 40% power” bug? This really causes a lot of problems, including losing the mail account settings. I am constantly having to remember to cradle my device throughout the day so it can make it. Also WiFi is basically unusable if the battery is below 50%. The device will just turn off. I am using 1.4 vanilla. I am grateful to Helmi and the community at large for all the great work on these devices. It seems it would be good to fix this issue before all the ROMs are gone.
TIA,
sbl
[EDIT] _TB_TB_ nailed it. Bad battery. Posting this over WiFi w/only 20% battery left. Yeah!
Your battery may be broken (one or two of its cells...). My battery did get broken... (Yes, the phone kept turning off at 40%)
got exactly the same, but mine dies at 58% [email protected]#
You really think it's a broken battery or could this be a software bug.

That depends. Turn the phone on, run camera app. Let it stay on. Wait till the phone dies. Turn it on again. Run camera. Let it stay on. Repeat the procedure until the phone fails to pass the "stripes" screen. This should drain the battery down to its "real" zero. You will know if its a software bug or a battery issue.
RE: bad battery
Thanks, _TB_TB_. I am trying a different battery. Will also try the camera test with each. I'll post results in a day or two.

Thanks, _TB_TB_
You were right. Guess that explains why ALL the WM5 ROM's I tried had the same issue. :^)
New battery = Happy user
Thanks again,

No problem
I simply had the same issue (battery damaged by the car charger...).

HTC Diamond battery dies without warning

I’ve get a HTC diamond from a friend and am having problems with the battery. I’m trying to figure out the best thing to do.
Generally I’ve found the battery is a bit low in capacity (as others have mentioned on the forum). But more recently I’ve found that the phone will suddenly die, without an battery warnings. The battery suddenly seems to be fully discharged.
I’m wondering if this is a problem with the battery (or more worringly) with the phone. Is there any battery monitoring software that might be informative? Or should I just buy a new battery and keep my fingers crossed?

You could try this for testing the battery:
http://www.spbsoftwarehouse.com/products/benchmark/
You may need to check it against someone elses benchmark to get an idea of a problem or not. I think the battery test is a long one though as it has to run it down completely after a full charge.
You could try disabling any programs that automatically connect to the internet (eg. email) and I think there is a cab somewhere that will disconnect gprs/3g/hsdpa when there is no activity. If I find it I'll post it here.
I found that the Auto Adjust Backlight used up more battery than needed so just set it to the second marker on left (start > settings > system > power > backlight). I'm sure there are many more options to save battery power that are mentioned in other posts but I guess you have already been through them.
I found that a full discharge then a full charge while the phone is switched off completely (not in standby) helped a bit but not much.
There has also been some problems with peoples battery monitor not being accurate. Like it saying there is 25% battery when there is really 75% of power left. But this problem has been few and far between.
You can also go into your settings/notifications and set a notification to let you know when your battery is about to peter out on you.

[Q] Phone Signal and Battery Drain -- is there a correlation?

Hello Everyone,
I am new to the forum, but not totally new to rooting and flashing ROMs. I have a MT3G (second android phone to come to the market...yes I'm old school ), rooted and flashed CM7-Gingerbread 2.3.3 and it's working very well.
I also managed to buy a NookColor, immediately rooted it and flashed phiremod nook v5.1. and everything is very good. My Quadrant Score is 1485
However, what I've noticed is that if I compare the battery usage on mytouch 3g vs the nookcolor I see something interesting and I think it might have to do with the overall battery drain I've noticed on the nook....I'm hoping someone here can shed some light.
When I go to my settings > about tablet > battery use, I can see a graph on the top. If I click it, it shows a nice relationship between time (x-axis), battery % (y-axis) and underneath it are 5 variables (Phone Signal, Wi-fi, Awake, Screen on, Charging). These variables are key because you can see what is really draining a battery.
See the two attached images. One is from mytouch 3g and the other is the nook. What you can see is that when my nook is sleep, it drains a lot faster than MT3G and in fact what you see is that the PHONE SIGNAL is constantly on, where when my MT3G is sleep, the PHONE SIGNAL IS NOT....
Is there a way to completely remove this 'phone signal'...I suspect we can get more battery life out of our nook if we can just remove this!!!
Thanks for reading.
easy to do if you have adb.. otherwise use terminal.
rename the following files in /system/app
Mms.apk
TelephonyProvider.apk
Phone.apk (phone will keep forceclosing.
reboot.
If you are not using adb, just force power off using the power button.
When it comes up, you will have much better battery life.
Yeah, I saw that posted somewhere, and I've done that. So does the phone signal still appear on yours after you renamed it?
I wonder if this procedure is enough.....

Enough to remove Phone from being listed in Spare Parts? Yep. It won't change anything.
CM7 is really bad with the battery. It doesn't sleep properly. The phone or lack of phone has nothing to do with it. It doesn't have a cell radio after all ;-)
Apparently there is a bug and it crashes or something? when it sleeps. I read that the devs just disabled sleep until they can get it fixed. I think that will probably happen after video is all working.
It still easily lasts through the day with a fair bit of use though. I just charge every night instead of every third ;-)

Okay, so it's safe to assume that the devs are working on this for future ROMs/Kernals? I really like my nook even though I just got the wifi-xoom today.
There's already been a 20+ page thread on this, where comparitive testing found no actual diference in battery life by removing those functions. The result is a purely cosmetic change where the power consumed under "cell standby" is shifted to "phone idle" or something else, I forget exactly. Any perceived improvements in battery life are a placebo effect and/or simply the result of the variables in different day-to-day usage.
Removing them also causes Market problems with certain apps not showing up due to "incompatibility" with devices lacking those functions, which I suspect is why they are not removed in the first place.
The NC's "high" power drain on CM7 is because it's not allowed to actually sleep due too a kernal bug which prevents it from reliably waking up. This will get fixed eventually. Right now, "sleep" simply turns off the screen.

New battery not solving shutdown problem

Z1 lollipop 5.1.1
build n. 14.6.A.1.236
kernel ver. 3.4.0-perf-gd26777b-00851-ga8b7b55 19 november 2015
It all happened a month ago, after an update, the phone battery registered low and the device reboted, and for the first time in the phone history, I saw, at boot, the "app optimization" dialogue, that kept chewing at what battery life was left.
So, I replaced the battery;
at first start, all seemed OK till I hit an app (whatsapp I think) and the phone displaied the low battery warning and went down.
Same, after a full recharge, when pressing the camera hardware button.
Oh, I also had the discrepancy between the charging icon , which reported 100% charge, and after maybe 10min. 50% and, you know the story.
Now, at the very moment I am writing, after a full charge, 24 hours ago, the phone, without the sim and the SD cards, but left on, registers a charge of 93% (only wireless on, to invite some disharge); of course I cannot check the watsapp, but I took some pics, and the phone stays on.
What do you reckon, I am bugged, as android 5.1.1
should I hang on the phone, which, by the way, performs(ed) pretty well, even though marsmallow is not an option, with the 2GB mem. at least in a bog standard state (i.e. not rooted)?
Thanks
A little update: after two more hours, I started using the browser, and after viewing a couple of pages, the phone swiched itself off.
Now, the charging icon, visible, when phone is off, show a 1% charge.
So, the software battery meter, must be well off the mark?
Last addiction: after an hour, the status light is green (phone charged?) and the charge icon, displays a 100% level.
It's your say, now.
I have this problem and battery replace didnt solve anything here too, but I'm on nougat. I hope someone know a solution for this.. But I think It is some kind of hardware problem.
Little update: after recharging, I switched the phone up and let it play some video on youtube;
well, after maybe half an hour, it went down, and as soon as I plugged the charger in, the icon showed 80% charge, which I allready experienced, dismissing it had a fawlty reading, but, with some afterthought , would be in line with the actual battery drainage ( remember that without any activity it stays on indefenetly) and is, as if, some internal mechanism -either hardware or software, is programmed to switch it off at that precise level.
Just a thought, is there somewhere, the level of battery disharge can be set, at our discretion before the device shuts off, say 15%?
I do not seem to find this specific setting, currently.
It is less credible, as time goes by, to think of it as a specific device/brand problem, given the fact that all the major players ware, seems to be affected, and allowing for differences in platforms, the common denominator would appear to be the software itself.
Exact same problem
Some time ago, I replaced my Xperia SP's battery.
The "used, like new" battery I ordered was as bad as the one that was to be replaced, maybe even worse.
I complained, got another-one. This other battery works great.
Remember: There are no "new" batteries out there, just used-ones.
Some are still good, some are dead.
I don't know where replacement batteries that are new should come from... Sony has never sold them as spare parts. I don't know of any company that produces batteries for Sony phones and sells these batteries on the open market.
I only know of third party spare parts for iPhones. Apple has sold only like 20 different models since 2006.
Sony? More like 100.
Producing third party spare parts just isn't profitable in this case. That's the reason why there aren't any.
Any seller who claims to offer "new" batteries lies. At least if he didn't take them from some never used devices.
I'd be HAPPY to be proven wrong because I also need a new battery for my Z1.
Besides, it's no wonder all our phones' batteries die at the same time. They are all the same age and have had more or less the same amount of charging cycles.
Also, it's no wonder they all die the same way (suddenly empty).
They all (more or less) came out of the same factory.
It's like with cars, same model, same problems.
A Peugeot 206 always has problems with the Zylinderkopfdichtung (don't know the English word, the rubber thingy in the motor that keeps water from mixing with oil), some stuff with the wheels or the exhaust flies off because of rust... for the third time in 5 years...

Your allegations, are worth investigating.
[solved]
Very important updates.
There seems to be an "xperia battery bug" which kicks in at every battery change.
After having done all the calibration stuff, I re-opened the phone and took the battery connector off, while the phone was on.
Then, did the same, with the phone off.
After three or four days in which the phone did not seem able to start, (rebooted at the first stages of switching on) the phone magically booted up with, and what's more important there was no dicrepancy, between the battery charge level, shown when you plug in the charger, with phone switched off, and the charge level presented by the software, once the phone is on.
So, do not give up your still worth device!
Only thing I noticed now, is a sligtly faster battery consumption, even in stamina mode;
could it be related with the post above?
Maybe a new custom ROM could fix the problem, now that the phone seems stable.
Similar problem.
Phone shuts down when 2 to 3 apps are working simultaneously. It first heats up and then suddenly dies.
Secondly, it sometimes dies on 60% and other days it can work till 1% too. Sometimes after a reboot, it shows the battery percentage abnormally.
I love this phone so i m not planning to throw it away. On the other hand, i cannot find an original battery in the market.
Just chuck a suitable battery in and do the procedure I described.
My battery is not original either, so no problem.
As far as the battery consumption, it seems to be better now, after a week of use.

Battery Issues

Hello.
I'm having trouble with the newly replaced battery on my rooted Xperia Z1 (with android 5.1.1).
2 months ago i replaced the battery because the old one overheated. The new battery has been fine untill a few days ago when it told me all day that it had 50% left. I found that weird so I didn't charge it to let it run out of battery so I could charge it to 100% and recalibrate it.
After the phone suddenly blacked out the battery wouldn't charge any more, so I took it out and messured it's voltage to be around 2.5. So I jumpstarted the battery back to 3.5 V and was able to make it charge again. Even though the battery functions like "normal", it still says 50% all the time with few exceptions which does look to be the correct battery level. The power management app disappears from settings whenever the battery shows 50% and reappears when it shows the correct level.
The battery indicator shows the correct percentage when charging, but not otherwise.
My theory is that there is something wrong with the software regarding the battery management and that it let the battery use too much of it's voltage. I've seen people with similar problems (50% battery indicator and disappearing power management), but the only solution there was to replace the battery. It doesn't seem that likely because of the software being buggy and the battery is only 2 months old.
Here's some screenshots of the weird behavior:
imgur.com/SXSMdzi
imgur.com/OcYKHjA
(Couldn't include image because I am a new user)
As I were writing this, it began discharging while hooked up to a charger. Seems to be a bit unstable.
Would appreciate all and any help
Hello!
I also got similar issues. I've read and try anything to find what happened with my Z1.
First, in my experience, some says (on internet) it's Android problem called Sudden Battery Drain Syndrome. I've tried apps like repair battery etc. and calibrator to fix it. Still the same the battery drain badly.
Second, so I am continuing my investigation on internet. I read from xperia care etc and I found that android Lolipop (5.1.1) terribly sucks for Xperia Z1. Many Z1 users confirmed this. Not just the battery problem, there are bugs also, like touchscreen, screen flickering etc.
Third, after knowing this and read like 2 hours to find the solution, I found in this forum that it's better to downgrading the android version back to KitKat or JellyBean. So I installed JellyBean firmware. Just now finished. I hope it'll be good again. I'll inform you.
NB: Factory reset also won't work
Hello, nice to get some response on this thread.

I tried battery repairs, calibrators and so on. Did not do anything for me. After reading up on Sudden Battery Drain Syndrome, I'm inclined to say that it doesn't seem all that similar to my problem.

That is interesting to know. I have experienced alot of those problems. I was thinking about upgrading to a custom unofficial Android 7 for xperia z1, hearing this might be the thing that makes me do it. It's always such a hassle to download apps and set up from a new install, so I've put it off for a while.
Some days after starting this thread, I ordered a new battery. The old one started to do the same thing. Seemed like I could jumpstart it again, but I don't see the point in doing that every other day.
The new battery has been working great for almost 3 weeks now. I still have the Lolipop problems you mentioned, but the phone works as it is supposed to. It acts up from time to time, but I suspect that being because I use Greenify and CPU tuner to make the battery last longer. I might be upgrading to Android 7 and if that fails, I might downgrade.
I'm hoping I was unlucky with the last battery because it lasted so short and that the problem was only related to the battery. I will post updates here if the new battery also suffers.
