Help Battery problems since update

About 7/8 weeks ago I had my S4 updated to 5.0.1 and I like how it runs now, however, I'm having problems with the battery. It drains a lot quicker and this isn't a problem, but what happens is when it reaches between 30-50% my phone will go off, come back on and then drop to somewhere between 1-8%, normally 1% or 2%. It's really annoying when I've charged it fully and it shouldn't be dropping THAT low when it's on 30-50%. It happens quite frequently and I can't think WHY this is happening. Also wondering where all that energy goes because my phone turning off itself and dropping from something like 30% to 2% is huge. Anyone have any ideas? It's really frustrating!

Thanks in advance for any help!
 
Hi. Yeah i have noticed that since the last LP update my batt drains much quicker than usual. It's not as drastic as what you've described though. What's more annoying though is that when it's switched off i now get a gray battery logo and a short vibrate every few secs. It doesn't seem to charge. I've had to go in and clear cache and do a battery dump at least twice now.

Was this half tested update created by a Microsoft programmer i wonder!
 
Mine had major battery drain for the first day or two, but it seemed to work itself out. I had to spend a good bit of time going back through the settings, everything, and I mean everything was changed by the update. I still haven't figured out how to reset some of my notification sounds. My phone whistles at me all day and I can't get it to accept my sounds as the notification!
 
I've taken the plunge and did a factory reset, as my home screens were playing up as well. Apart from the battery issue everything's just about sorted. I've downloaded a battery calibration app from the play store to try out. I'll let you know if it's any use.
 
Mine seems to be working OK now. What I've discovered is if I want to charge it up when powered off, once the charger is plugged in I've got to press the home key for a couple secs then I see the batt charge graphic. Kinda nuts, but it works.
