My Lapbook (bought December 2018 on Amazon.de) had about 4 hours of battery life for my usage which dropped to about one hour all of a sudden, Osiris Battery Bar Shows wear Level of 0% but battery drain of up to 50000(!)mWh instead of the usual 4000 to 5000.
- reinstalling from original emmc Image with and without updates.
- installing newest Windows 10 build with and without drivers,
- Linut Mint (Ubuntu based) - it didn’t change.
I tried to contact Chuwi support via e-mail, no reply.
I bought a third party replacement battery from AliExpress (marked as Sony cells, weight slightly higher than original) - no change.
Any ideas what the problem could be?
