[Q] GT N7000 not booting, low battery - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hello, I've had alot of trouble lately with my note, but I thought I'd fixed it.
It was overheating and screen was flickering, battery going from 100% to 1% in 30 minutes.
Just now my note shut down and it just shuts down after the boot logo, not because there's a fault in the system, but because the battery is low.
When I charge it, it says 100%. When I unplug it and charge it again it says 100% or 77% or 98% or something random. I can still enter recovery and it will also start booting sometimes. I've tried 3 different cables and 4 different batteries. Warranty has expired.
What can I do?
Thanks in advance

Buy a new battery!

I've bought 3 different new batteries, I doubt it's about the battery...

Battery won't charge

Hey, i simply put my phone to charge and nothing happens, battery status appeared as "not charging" (free translation, i'm from brazil therefore my phone is in portuguese), now the battery is fully discharged and just stays in the "charging screen".
I know nothing about android and stuff, but my friend unlocked the bootloader when i had other problems with the device...
Sorry for my english and lack of information, but i don't know what to do and the warranty is over already
No one? Please guys!
You tried another Charger? If that won't help, it's an hardware issue. You still can try to get an replacement, because an unlocked BL has nothing to do with broken hardware. This can happen with an locked BL, too.

Problem with my xperia.

Hi there. For some time now struggling to restore my xperia to life. It shows that the battery is fully charged, but after a few minutes of use switched off. I enclose two films, the first without the charger, the other connected charger. I tried to flash kernels, roms, go back to the stock rom. I am currently on CM10.2 stable. In each ROM symptoms are the same.

See if this relates to your issue... http://forum.xda-developers.com/showthread.php?t=2526618...
I've read a similar post in the ZL forum as well... apparently there's some quirk where the Z and ZL batteries can end up in a state where the phone won't stay running... it's possible it's a battery failure... which should be covered under warranty... check the other thread.
I have read about it, the symptoms are the same. Voltage is correct, the battery health: good, then, is just to replace the battery.
Thanks, I'll write here what was the problem.

Charging too long

Hi Everyone
My phone is charges 0 up to 100 taking 3 hours i'm used original 5v1a charger,5v2a(note2),5.3v2a(note3) but charge time the same using original 4.1.2 rom or cyanogenmod not changed everytime 3 hours i love my phone but im bored this subject how can i do?
sorry to mistakes it's translate
Charging time depends on phone electronics. Has nothing to do with used charger. Don't think this can be changed. This might be hard wired....

How long normal charge are your phone?

Device shuts down at around 5% battery

Well, my device has got the above mentioned problem. Every time the battery reaches about 5 % the device shuts off as if it was completely drained. When I try to turn it on afterwards it only shows the empty battery symbol and I have to charge it. The weird thing is when I charge it enough that it turns on it shows like 7-8 % battery. Now I suppose the device just shows me wrong numbers and is actually empty when it shows 5 %, so I guess it's a calibration issue? Did anyone experience something similar or know a possible fix? Thanks guys.

Not that I know of, just fyi it's not great for the battery to discharge it to single digits all the time

You are right , when you reach 5% it will shutdown.

Thanks for the input. I know and I try to avoid getting low on battery as often as possible, but I've had the problem since I bought the device back in January. I just can't accept 5 as the new 0.

So yours does this too? I can't imagine this is normal behavior. Or is it some kind of protection mechanism?

Yup all the time, thats why before it hit 5%, time to charge... For me its ok
Nope mine goes to 0% before shutting down. Doesn't make sense. Maybe it's your rom/kernel

If youall keep letting it go below 5% one of these time's it won't take a charge and you will be getting new phone's. Not good to run lithium ion batts to zero.

I'm running stock ROM with franco.Kernel r21, nothing fancy here, completely stock settings without undervolting or anything. It also happened when I was on stock kernel. It's really awkward behavior and I never encountered this on any other device. I'll probably go and see if I can get a replacement.

I have a similar problem with a 32 GB Nexus 6 - it randomly turns down completely at all different battery levels - 15% on up to 60%.
I've Google'd and found some people complaining about the issue. Ultimately I was unable to resolve this (still completely shutting down 2-3 times a day). The only solution was to plug into a power source and then I could turn it on and unplug.
Sending this device back to Google for a swap.

ZW3 does not charge now and then

Every now and then I grab my ZW3 and put it on and head out to work.
On the way I notice it is dead.
I would say at least once every 2 weeks it will not charge.
I put it on the charger every night and "usually" watch to make sure the charging display is on
I may skip that sometimes though.
Is anyone else having problems like this?
Happens to me when the contacts get dirty. When I clean them it's better again.
