Can you please be a bit more specific? It's difficult to help if we don't have much information to go on...
Are you on a custom ROM?
What has changed recently?
Have you recently installed any apps or Mods? Has your usage changed? Are you using the screen more? Are you regularly in areas without adequate cell phone reception?
All of the things listed above will affect Battery Life. If you're suspecting it's a rogue app causing it, the best solution is to use greenify
to find and squash those programs.
I know other users also use Better Battery Stats
in order to find out what's causing battery drain, but I haven't used it in over a year, so I can't comment on how well it works nowadays.
Hope this helps!
