[Q] Sudden battery drop?

Ok, i searched and couldnt find anything like this, so if there's already answered somewhere please point me in the right direction.
Lately, sometimes i've been getting these sudden drops on battery when i check the chart it looks something like this:

Info:
Stock JVT ROM
CF-Root 4.3 Kernel
Yes, i've flashed my phone with another ROMs (CM7.1, JVS, JVT) and yes, i've calibrated the battery. I started getting these even before i started messing with the phone's ROM/Kernel (with the stock unrooted JVH the phone came with).
Is it normal? Is there something wrong with the batery?

That looks more like your phone is doing a reboot. When your phone reboots it uses some battery so the "stats" will show lower after the phone have booted again.

i didnt reboot my phone and i don't really think it rebooted (not sure tho)

Noticed it looks like there was a signal drop at that time? When your phone loses signal it spends a lot of power searching for it, so that could explain it.

That screeny clearly shows a red area in signal line, so certainly signal dropped so it could be the reason for such a huge battery drop in such an instance. Has happened to me before, when I keep my phone switched off for some minutes.

[Q] Galaxy Note 1 bricked, inflated battery

Bought in November of 2011, my Galaxy Note 1 does not react to any (combinations of) button pressing anymore.
1. It was bought in Germany through Amazon.de; the so-called international unlocked version.
2. Absolutely no rooting.
3. How it got bricked (or dead): at some moment (while using) it stopped reacting and automatically reboot but failed.
4. What happened before: around one month before that, I found the original battery last less and less time, and what's more of my concern, the battery is obviously inflated, which might present a safety problem. So I bought a new battery through Amazon.com (actually two, but the first one did not work at all, so I bought another from a different seller; didn't expect that batteries can also have this kind of "fitting" problem).
5. What I have tried: I didn't spend much time in this because I didn't have much time. What I tried was to use Ordin to install a new (stock) system to it, but failed because Ordin said something like "connection problem". Later the phone cannot enter the download mode because it does not react to any button-pressing anymore.
6. Could it be that the battery is dead: I hope so, but it seems the battery cannot be charged (I tried to charge it for many times).
7. All those happened a few months ago. Today I happened to see the original battery of the phone, and found that it is amazingly so inflated that it looks like a balloon, and I wonder how could it be fitted into the phone if I didn't bought a replacement (and if the phone was not bricked, of course):

I had the same problem. I had to use a friends note to charge my original battery after draining it completely.

try to use one of those universal chargers.they're cheap(about 2 euros),but they to the right job. Or use another note to charge the battery.NEVER try use odin on less than 70% battery.

Battery life

My battery life is really bad that i have to charge the phone twice a day sometimes more
i tried every thing said here on the forums, i disabled LG bloatware, i lowered the brightness to 0% but with no luck
so is the only way is to unlock the device and install a custom rom? or could it be the battery hardware itself? because i realized that the battery charges really fast, also i just got the phone 4 days ago is it normal that out of the box the battery life is this bad?
EDIT: it looks like i'm running UAE firmware, would it help if i flashed a kdz file for a European firmware? if yes which firmware should i install from these http://lg-phone-firmware.com/index.php?

Using a different kernel would be the better idea IMO

[Q] SAMSUNNG note Switch off problem

Hi All
Im just join this forum to get help for my Galaxy Note GT - N7000 problem.
My phone getting switched off when Im using my phone continuously for 5-10 mins. After that when Im restarting the phone its showing low battery Signal or sometimes not even start the device due to no charge in battery. When I connect to the charger its shows the charging level again at the current position ( With good amount of charge ).
But Im not facing this switch off problem while Im taking long in the Phone. I have done factory reset but the Problem not solved.
A person from the service center told me that its a software issue and need to reinstall the OS. But it will have Dead Risk. If it stuck during the OS update the Phone will be dead and I need to replace the Mother Board.
Im really surprised about this king of statement, I didn't understand how a hardware can be dead by OS update ?
Any one can help me out with the solution and what need to be done to get rid of this problem.
Thanks in advance.

Buy a new battery.
The service center man ist talking bullshxxx for 50%. No software problem.
And read in the sticky threads here about the hard brick risk when using a Note with Android 4.0.x.
So do not make a factory reset now - until you understand what you are doing.
As said before: this behaviour is a good hint for replacing the battery.

Poor battery life

My device is not very old. It's about 1 year now and battery isn't as good as it used to be. When I got it after school I had minimum 50% no matter what I've been doing and atm it's 24% which is disturbing.

Check for battery health in 7378423 to see if it had any wear out in battery capacity. Mine is 31460 (1+ year, when buy it is 32000, Sony is always add more to make the battery last longer )
And check for any apps that run out of battery, malware too (There are some Android malware which mine Bitcoin/Litecoin and make phone hot and run out of battery)
Also check your kernel setting or reflash ROM if nessesary.......
Mine is 1,5-2 day battery life with typical behavior.......

Well, my battery says 31440 when at 86% of charge. I haven't got many wake locks in betterbatterystats either so I'm not sure what could be the cause. I'm on stock kernel. Thanks for the heads up on that mining malware. I had no idea it went over to mobile devices. My phone actually gets a bit hot after some regular usage, but nothing out of ordinary I guess. I did lots of mods to the stock rom on my own so I'm not that keen on reflashing. I'd rather find out what could be the cause of that poor battery life and fix it by myself.
Any other suggestions and things to try?

You can reinstall your Firmware, and see if the battery life would be better. And my Wakelocks have i solved with the App DS Battery Saver.

Strangely enogh my battery was at 2880 after only 140 charge cycles.
Then by accidient it deep discharged (problems with not charging, hard reset etc. until it was fully 100% dead) and now is back at 3130 with only the first charge cycle counted as 1.
Not the case here since your's has a good number, but I wanted to add this information.
