I can't find it
This is everything in my settings: http://imgur.com/a/SypKz
If I go into 'About device' there is some battery information in there but none of it is clickable. I'm so confused. On my Nexus 5 there is a 'Battery' option in the main settings menu.
The only thing I can think is that I've used a package disabler app to get rid of some bloatware, but I've just double checked and I have disabled anything that would be related to the battery information.
Should be here, which version of android and is software customized by network operator? If you still have samsung smart manager, theres a link to the battery setting on the app
