After installing 2nd beta it changed my battery charging to 100% instead of the 80% I had set it to. When I went to turn ot back on it said I had to turn on customisation service and agree to giving you access to data from all my apps. This just outright datamining. I then had to go through a long process to opt out. This breaches GDPR where I should have to opt in not out. I never had to have this to use battery preserve before. Please remove this. I have notified the Information Commissioners Office in the UK about this breach.
That's bizarre. Surely an oversight to require that! My battery protection is on, but set to ″Basic″. I can't remember what it was before, but I probably did choose this as I prefer a full charge.
Battery protection also reverted back to 100% but I had none of the other issues mentioned here, set back to 80% no customisation service prompts? and adaptive brightness was still active. .
