Honestly, at this point, I don't think the Note Edge is worth it. In fact I'm going to pay more just to be done with my Note 4 before my 18 month period is up. The phone was great when it was running Android 4.4.4. It was fluid, smooth, and could easily last into the night with heavy usage which included playing audio (from an SD card) via Bluetooth for 3-4 hours, taking pictures, using the Facebook app, and surfing the internet.
Then Samsung and/or Verizon decided to push out Android 5.0.1 and it has sense turned my phone into a complete mess. I had to factory erase it, twice. Erasing it the first time and restoring from a backup didn't work, I had to erase it and start from scratch. Even then it didn't fix all of my issues. Battery life is now abysmal when the phone is actually being used (but standby time has been increased), Samsung changed the camera app so that the shutter button is no longer on the Edge panel where it was with 4.4.4, I get constant stuttering when accessing apps, and Bluetooth audio skips like crazy whether I'm using my car (Bluetooth 4.0 with aptX, my Bluetooth 4.0 headphones with AAC, my UE Megaboom, or my Bose SoundLink Color). I used to be able to achieve a solid 12 hours of usage but now it's reduced to 7, maybe 8 hours if I don't access media-heavy websites.
The Note Edge was my favorite smartphone until the update. I felt the same about the S5 until the 5.0.0 update but I didn't think that Samsung and Verizon would make the same mistake. Alas, I was wrong. At this point I wouldn't even spend the extra money on the Note 4 (my fiance has one and she is experiencing all the same issues as me in terms of performance).
