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.

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.
Hi
I'm trying to calibrate my battery but just cant find a guide, is there any steps I can follow?
Thanks
There is a big guide by senior member. Check this out:
http://forum.xda-developers.com/showthread.php?t=2489594
Edit:
If you have CyanogenMod you can change the processor mode (you have different profiles like power save etc.) which saves a lot of battery. Alternatively you can do it like in the guide using play store apps for CPU tuning.

That thread has incorrect advice. That afore was for nicad batteries but modern batteries use li-pol and doing what it suggested in that thread actually ruins them

But using CPU Tuner (for save battery) doesn't.

many things sorted out. Well it's mainly for Notebooks, but those are the same type of batteries.
Essence of it:
There is no Overcharge,
partially discharges (not full) are much better for your battery
Full Discharges are bad.
This said:
There is a point in "calibrating" your battery:
The battery itself will not directly benefit from a 100% discharge/recharge cycle (the opposite, in fact), the calibration system, however - which serves as the battery's life meter - will more accurately predict remaining battery life as a result. This will not increase the life of the battery, but will allow you (as a user) to have a better gauge of the remaining on-time.

You only should do this, if your battery drops to 1% and remains there for longer than average under that condition.
Lets say, your battery drops to 1% and you can easily keep going over half an our with screen on but it should be dead by then.
Or the other way around:
Your device powers down at 5% (jumping from 5% to 1% and then powering off)
Then you most probably need to calibrate your device (not the battery) to match the actual capacity of your battery.
This can only be done by compeletly discharging your phone and let it power off
edit:
i just let my device charge over night. so i know i'll easily get over a day. I was never in a Situation where my battery was so low, that i need to be afraid, that it turns off
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?
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...
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.
