I’m currently on 18.104.22.168-U and everything is fine.
As I stated in my previous posts,I get the same battery life on almost all firmwares
(plus/minus 10 minutes)
As i said,I don’t have lag
(touchscreen works flawlessly)
About battery drain when you’re below 20% :
When I’m below 20% and when battery comes to 7% it drains to 1% in less than a minute.
I think that’s the way meizu is calibrating battery,
it’s bad cause it’s draining fast when bellow 15%, but we can’t do anything about it,
when it comes to calibration it’s meizus fault.
I usually don’t drain my battery below 20% .
When it’s on 22-20% I plug it and charge it.
I’m draining the battery completely twice or trice a month but not every time.
When draining your battery completely from 100% to 0% every day you’re shortening the battery health and lifetime .
On apple/samsung/htc forums there are threads about draining the battery completely 2-3 times per month to prevent short battery life.
Draining and charging the battery in this fashion it will last much longer.
