If performance seems good and battery is about 10% drain per hour... then I assume you are noticing normal feel when the CPUs are running hard for a moment or two. Your hand or case cover will keep the heat up when that occurs.
There are a few threads in the Q&A section about battery drain, you may find them useful. If you have a good sized media library, the system will thumb nail cache and index media if using Google apps like, Music and Gallery. The latest Play Music will fix the issue with indexing. But I had to use xposed with Winam module to disable thumb nail cache and DVFS for both better battery charge indication and free up memory from thumbnails being created. For me I had over 300+ MB of cached images that would grow depending on how much media I would store.
