SUNZOS Galaxy Note 4 Battery, 4320mAh Li-ion Replacement Battery for Galaxy Note 4 N910, N910U LTE, N910V (Verizon), N910T, N910A (AT&T), N910P (Sprint) [3 Years Warranty]

Great product

When my note 4 won't stay charged as long as I need, I buy a new battery. This one stays charged all day with regular use. If I linger on games a lot it does run down faster but for such an old phone I get a good charge

The second battery on my Note 4 needed to be replaced so I hunted high and low to find an original Samsung battery which I purchased form an Amazon supplier. After installation the phone went into a start up loop wherein it would finish the Samsung banner screen and then shut down momentarily and restart repeating this cycle over and over. This would continue until I pulled the battery out. I called the supplier and they promptly sent me another "original" battery . . . . same result as before. Not ready to spend several hundred dollars on a new phone and finding this to be a "common" problem on Note 4s I tried all the tips and troubleshooting with no success. I then called Samsung and they gave me the name of an authorized repair shop. When I contacted them they said batteries have to be calibrated for the phone and knock off batteries or original ones that are old can be problematic. He also said his Samsung supplier didn't have any Note 4 batteries on order and he doubted they would. Sooo I decided to take a chance and scowered Amazon paying close attention to those batteries with the fewest ratings of 3 and below and selected this Zunzos 4320 mAh battery. IT WORKS PERFECTLY! Be sure to follow their instructions to charge and completely discharge the battery up to 5 times initially. Time will tell how long it lasts but I'm able to put off buying a new phone for awhile.

Battery worked great for 5 months. After that, extremely warm and discharges in less than 8 hours.

I didn’t want to trade it or throw out my Note 4, I still had it because it was a gift from someone dear to me years ago, the phone didn’t hold a charge anymore and I decided to see if the battery was the problem, I got this and boom, my Note 4 is back on top, I can now see all my old photos and videos and everything I used to take on the phone lol I think this battery is even better than the original the phone came with

They are great with the warranty the battery I received didn't last a month and I followed all of the directions. I contacted the seller to give them another chance before I wrote a review they immediately sent me out another battery which was another dud and I got frustrated and just went to another seller to get a different battery. I wind up charging the battery more often than the battery that I was replacing.

It was my second SUNZOS cellphone battery. Both worked well and I'm happy with battery lifetime.My main concern or fear would be a poorly engineered battery setting itself on fire destroys my phone, data, set my house and cat on fire. That wasn't the case with sunzos. Phone works fine, phone doesn't get hot(er). I spent few extra $ just to get this brand. I hope Sunzos doesn't get smug and hike price.

Just to confirm this battery does work in the Note 4. Even now its still holding a charge, although I noticed the battery gets hot fast, and is definitely nowhere near as good as the stock battery. Its cheap so I dont expect it to be amazing, but I do expect it to last at BARE MINIMUM 1 year. This battery is already bloating after 6 months of light use. I dont even use my Note 4 as a phone, its a back up media device and this battery still went bad that fast. I have used some of these other aftermarket batteries on here, and they lasted much longer.
