Explanation:
This is a Samsung tablet from 2014, currently has LineageOS 18.1 (Android 11), the last it can get. Since it's unused I did a little experiment until I find someone who will use it. Today I have found so here is the post.
After charging it to 100%, I disabled Wi-Fi connection, put it on battery saving mode and it's been on for more than 2 months. Battery is still in good condition after all these years I guess. :)
It's not that surrpisingly, they doesn't use it at all and the rom is Lineage;
i once remove all google bullshit from a shitty 80€ phone and used it as server for a discord bot, it would last roughly a week per charge, it also had a version of android that was way too heavy for such a cheap phone, if i had installed Lineage and an older version (android 7?) It would've lasted way more probably
Yeah, not having anything Google related surely increase the battery health. Also mental health.
