The battery works great....Make sure you follow the instructions and let the battery charge w/o use for the given amount of hours the instructions say...Have had no issues the battery charges very fast now....

My note 4 was needing to be charged every few hours. That was a pain but I actually could deal with that. The real problem was that the battery would go from 35 percent to zero in 1 second. So I ordered this battery from best buy. While out shopping, I ended up buying a new $900 phone, partially because my research led me to believe that once you replace a phone's battery, it never holds a charge well. Anyway, battery arrives and I popped it in my note 4. Basically it didn't hold a charge worth crap. So I gave up on it and went with my brand new shiny recently purchased phone. Well that phone was a bust so I ended up returning it. So I decided to follow suggestions and let the battery I bought, completely discharge. Then I charged it for 8 hours without turning it on. Voila! I now get a full days use of my phone off of one charge. 100% at 7am. When I go to bed at 10pm I'm at about 50%. With my use being medium...a few web searches, a bunch of texting and checking email throughout the day. Bottom line: the battery works very well. Just don't expect brand new 2018 cell phone battery time frames/usage

I wanted to wait before writing a review on a battery. I purchased this 1/6/2017 and have been using it exclusively in my Note 4 since. It lasts the entire day, often with heavy use and has not yet shut down at anything less than 1% battery life. In fact, I have had numerous occasions where the last 1-2% of battery lasts longer than I ever experienced with the OEM battery. This is the 2nd replacement I have needed. The original battery got me through 14 months, then I got an OEM Samsung battery replacement. That lasted about 6 months before it started shutting down at 14-15% randomly. I needed a more reliable battery after the Note 7 fiasco. I decided to preserve my upgrade and see if the Note 8 or Pixel 2 was better than the S8. This battery has not let me down after 7 months of use. If you're still holding on to your Note 4 for a while, I highly recommend this battery.

Like other reviews I read, I too have had my Note 4 for just over 2 years. I was constantly have to charge my phone throughout the day. If i tried to use my camera or view videos or postings on social media, the phone would die even if the battery was at 50% or greater. I purchased this new battery just over 2 weeks ago. It is like I have a new phone. I use my phone frequently throughout the day - mapping directions, internet research, and social media. My phone will last all day and require charging only at the end of the day (14%!!). The battery charges quickly with the Samsung Rapid Charger.

Read and follow the instructions! Went to the store and picked up the battery read the instructions and installed it. The battery was at 50%, I used it for 2 days before it was depleated. (It seemed like there was something up as it would not die). Be patient & use it up, Then charge it fully! After the battery was discharged it took a full day to charge. (Do it over night on a weekend) After that WOW look out friends, I could listen to my Mom talk to me WAY to LONG. What once was a half a day phone is now 3.5 day phone again. I am a light phone user AND, I figured out how to shut off all the battery killing, data sucking apps off. As always if your depleting the battery heavily it gets hot. Let the phone be a phone & not a pocket super computer it runs long and cool. I love my phone all over again. This is probably why the phones are made differently today :( The sale with Best Buy was smooth, As long as you are patient and can wait 3 days then drive to an actual store.
