Help Terrible Battery Life?

So...I was reading all the reviews talking about how great the battery life on the Note 3 is, but...I'm not getting it and I don't know why. My phone has been off the charger for 6 hours and the battery is down to 67%. This doesn't seem right to me. Does anyone have any ideas? I tried to condition it where I let the phone die on its own and charged it to 100% before turning it back on. I haven't really done anything overly intensive today, just texting, downloading a couple apps, a little internet use, and the occasional streamed song. But, some reviews said they got like 13 hours of constantly streaming video. There's no way I could have done that at this rate. Anyone have ideas?

I've never read 13 hours constant video. What is your screen on time you are getting?

Samsung Galaxy Note 3 battery life test - GSMArena Blog

They tested multiple scenarios. The Note 3 clocked in at 13:32.

My screen time on is 1 hr 44 m. There's not way that drained the battery this much. And I have the auto brightness on.
Who knows what settings or anything they were using. Each scenario is different.

I would say 6+hours screen time is good your #s are close depending on your usage rest of the day

6 hours @ 67%

Id be ok with 18 hours for a full battery
:ditto:

With my S2 I probably would have been at 30% considering my usage over 6 hours. Last night before I went to sleep I had around 90% showing on my Note 3. Woke up at 10:30 and it showed 78%. :thumb: Been using it since then to post and read reveiws and it just now gave me the low bsttery warning at 15%. I'm very impressed with the battery life on this device.

Are my expectations just too high? I mean, with the EVO LTE, I'd take it off the charger at about 7 and when I was ready for bed at midnight, it would still have like 30% left with moderate use. At this rate, my phone will be dead by midnight.

Wait a minute. It dropped 12% while sleeping?

That's not good.

I just realized the LTE setting on the phone was on. Since LTE isn't available in my area, that very well could be why, since it would constantly be trying to ping for a signal. I changed it so it's down to just WCDMA/GSM now. If that drastically improves the battery life, I'll let everyone know.

Yeah, that would be an easy explanation. My OG Droid and Rezound would burn through battery quickly in weak VZW areas.

Supposedly your Snapdragon 800's on-chip LTE draws less power when trying to connect to a weak signal, but it could still be a significant drain.

Happy so far but only day one on the first full charge

I'll double check tonight and try a side by side with my S2. I'll try to have them both at 100%.
Big difference when I was really paying attention.

S2 1:56 AM - 10:26 AM: 95%-73%
N3: 1:56 AM - 10:26 AM: 100%-97%

Both devices had WiFi on and received 5 email messages overnight. The Note 3 is way better than the S2. I'm very, very happy with the Note 3's performance.
