So I just upgraded to an S4 (mobile) from my S3 (GPS only) and have to say that I'm really disappointed with the battery and charging. Last night, for example, I set the clock up to 95%, left it at 22.35, and went to sleep. Watch was in theater mode all night and I didn't check the time once. By 6am the battery was down to 61%. If you do the same with my S3, not even in theater mode, the battery will usually only go down 5-10% overnight. Also with my S3 I was able to charge back to 100% in under an hour after using the clock for a full day. I would charge back to 100 in the morning in about 30 minutes. Now take charge forever! Any tips on what could be wrong, or is this normal behavior for the S4?
