Spooky issues with battery life

[Justinkeyback]

Friends, I have issues with my battery life. One thing I know for sure, the battery itself must be good, it has to be software related.

One time I have a good steady battery life, starting with 10,080 mWh more or less, than it suddenly rises (after reboot or after swapping with Android) to almost 12,000 mWh. Days later, when I am trying to get new software installed and I have to install and remove software sometimes over and over again due to wrong settings, (mind you, this is with power cord plugged in!) I see the battery level drop to less than 30% in no-time. After reboot it says my battery capacity is 2,735 mWh and I have 36.4 % battery wear of a totall of 4,300 mWh!!

I do not get it. I had this one time before and after a while the battery gauge read again 9,800 mWh and once over 10,000 mWh, and no mention of battery wear. But now it is again on this low level and remains on 2,735 mWh. The funny thing is, that it says battery is 96% full and I see the ampere indicator (between powerplug and usb-cable) drop to .2 or .3 A which is normally about 1.5A when a quarter or so of the battery is depleted, so it acts as if the battery is fully loaded. That is weird.

As the readings are unstable I conclude this must be a software issue, as common sense says a broken battery can’t repair itself. So, how to find the villain? Which driver could be faulty? Anyone? B.t.w. it is only on W10 that I have these issues. Android is reasonbly stable.

Much obliged!

Battery meter issue. Not sure it can be fixed. The issue is the dual OS switching I think. If you were to stay in Windows all the time does it do it?

Hi Chris, you could be right. I used the OS switch several times and got a hunch before there is something bad with it, as if Android is not absolutely killed when switching to W10, vice versa. Now I will keep W10 on only for a while, leave the OS switch and really shut down and restart. This morning I tried it once: shut down, reboot, no effect. But perhaps too soon to expect good results. Thanks for thinking with me.

Just today the Chuwi returned to usual! After a reboot from Android to W10 … got again 9861 mWh, with 0% battery wear, really. Still, a bit below the 10,000+ I had for a short while some months back.

So it surely is not WYSIWYG. Don’t ever believe the battery is broken when the tablet suggests it is 😉 perhaps after three years of daily use … And don’t use the switch to hop from one OS to the other, always put it off first and then reboot.
