M8 battery strange behaviour

He folks,
at first, yes I read the FAQ about the battery.
It is winter in germany since a few months and tempartures are low. Li-Ion batteries have problems with such low tempartures I know that. But I experience some weird habbits of my M8.
I have 75% battery load and I get a call or I put on the camera and my battery level decreases to 10% or less. Sometimes the phone shuts down when I get a call. I think it has to do something with the vibration. It is very battery consuming. I switched it out since yesterday to save power.

The second thing is, when the battery level is about 10% and I plug the M8 into the wall socket via the usb meizu adapter the battery level increases up to 70% in one second. After this it will fully load to 100%. from 99% to 100% ist takes very long.
Does someone also have such a strange behaviour too?
Does a new battery solve the problem? And if yes, where to get one that works well?

same here...same strange behaviour with the original meizu m8 battery
cant explane whats happening..
i ordered a new battery and will tell if this going to be the same case with the new battery...

That's because of the LiPo chemistry. At certain temepratures the capacity of the battery just drops because the chemistry won't work. But this would be more evident as the battery gets worn. What temperatures did you have the problem at?

And charging, again it because of it being a LiPo battery, it's easy to charge it up to 70%, it doesn't take much, but the higher we get the more carefull the charge has to be or it might blow up like you see on youtube. So the charge current decreases beyound 90% and trickle charges the battery untill at 100% charge.

thanks for making tha clear to me Coninsan. I'm looking foward to hear you feedback lilM8.
The temperatures are below +5°C
