This weekend I updated my Sony Xperia XZ3 OTA to iode’ 4.0. I thought all was fine till I plugged it into charge and realized after an hour or so that it was charged to 100%. My phone was set with smart charging to stop charging before 100%. I went into the smart charging settings and reset all the preferences to default and then rebooted. Once the battery was in need of charging I again saw that it went to 100% unfortunately.
So it appears that smart charging is not working now. Is there an app that would automatically stop it from charging before it gets to 100% ?
