(Upgraded) Wavypo Galaxy Note 4 Battery, 3600mAh Replacement Battery for Samsung Galaxy Note 4 [N910, N910A, N910T, N910(Verizon), N910P] Note 4 Spare Battery [12 Month Warranty]

Worked excellent. Better battery when was in there to begin with.

It doesn't last long

I was quite OK with the first battery I bought for my Note 4 last year, then I decided to get another one. The second one I bought 2 weeks ago didn't go well at all much worse: it doesn't hold charge even provided I don't use video and music. After a call 10 minutes talking it drops down 40-50%!!! I would NOT recommend this product again to anyone!

Works great for an old galaxy note four

Good. Good

DON'T BUY THESE! Here's why... We purchased two (2) of these (Upgraded) Wavypo Galaxy Note 4 Battery, 3600mAh Replacement Battery for Samsung Galaxy Note 4 for two (2) different phones. I looked forward to using these upgraded batteries and really wanted to love them! So, we were certain to fully 100% charge and then 100% discharge the new batteries for 4 full cycles, which is a real pain to do, but we did it to ensure the best performance. Despite that, one battery failed within 1 day of use and the other failed in 16 days of use. Using either battery, in either phone, causes the phones to heat up and get quite hot! Regardless of the amount of battery charge (it could be 50% to 100% fully charged), the phones will repeatedly power cycle; power off, then power back on, constantly, over and over, until you remove the battery. If you allow the phone and battery to cool down, then reinstall it, within a few minutes, it just does the same thing all over again! The problem is something with THESE batteries and NOT with the phones; because the phones work perfectly fine with other batteries! No problems at all with the other batteries we've tried. So, we couldn't use these supposedly upgraded brand new 3600mAh Wavypo batteries that are total rubbish and don't work in the Note 4. We went back to using the original 3220mAh Samsung Note 4 Batteries that after nearly 4 years of daily use, are still way better than these Wavypo batteries. Using the Samsung batteries, the phones never overheat and never power cycle. In this case, we're better off staying with our OEM Samsung batteries. Don't waste your money on these batteries like we did! You won't be happy! They didn't work with our phones!

Doesn't hold a charge any longer than my bad battery. Maybe the one I got was old idk. But buy an oem one instead of this junk.
