5200mAh Galaxy Note 4 Battery, [2023 New Version] Upgraded Replacement Battery for Samsung Galaxy Note 4 N910, N910A(AT&T), N910T(T-Mobile), N910V (Verizon), N910P(Sprint), N910U LTE

The battery is nice, long-lasting, I feel like my old phone is new again. My father was using that phone for years and I want to keep it, but I did not expect that it is still possible to find good battery for that, I am very happy.

Keeps my very old Note 4 phone working great

Well got the battery and it started getting hot. I was replacing a battery that lasted 2 years and my phone started doing weird things and then a notification that battery was not keeping up with apps . So i got this one and it acted weird hot something . But after resetting my phone and and not using it so much thinking it was the new battery or my phone . So now it seems to be fine . Maybe my old battery was so bad it took a lttle time for my phone to calm down. So we will see. UPDATE. Wanted to say everything is fine with this battery.

I purchased this battery in Oct 2020. The performance so far has been great. It fit into my Note 4 without any problems. Hopefully performance will continue to be good. I will update as time passes.

5 MONTHS OLD AND NO LONGER CHARGES - AT ALL Purchased this on Dec. 6, 2021 worked fine for 5 months, and now it will not even charge. I happened to keep my old one that this one replaced, I put it in and it charges fine, so there is nothing wrong with the phone charging system. PURE JUNK . . . DON'T BUY

I used for a year, followed instructions for its initial charging and declaring protocol, ans began using it a year ago. In this space, I always wondered why no one ever came up with a subjective review, based on actual dats from measuring the true battery capacity in terms of actual mAH vs. advertised mAH. Amazon seems to have the best reviews still, especially with the help of FakeSpot, but even then it can only go so far when not a single review can give a simple measurement of an obvious metric. Until now, and I am that user. I bought a device which would measure the total charge in terms of mWH given to the BOANV battery. Since there is a residual charge of 8% in the battery, in charging to 100%, I obtained a value of 13200 (see first pic) mwH. Compensating for the residual charge, I would come up with a value of 13200/.92 = roughly 14,500 mwH. I would divide this value by 5V to get a value of 2900mAH. The only thing I can conclude is that after a year of use, the mAH falls below both the original galaxy note 4 battery specs of 3220mAh, and farther below its own advertised specs of 4800 mAH. But to be fair, I only got the measuring device now, and didn't have the chance to measure the value when the battery was brand new or unused yet. At 2900 mAH, the battery is at 60% of its advertised capacity. Granted, there were a few times I exhausted the battery to zero (twice at most) and perhaps a half dozen times the charge went below 20%. But since this is a LiFEPO4 cell, shouldn't it be more forgiving than lithium ion batteries in retaining charge capacity with battery drains? I have other phones I would like to install LiFePO4 batteries. Now that I have a nice and affordable tester, I can test LiFePO4 batteries to see which of them is the real deal, or if there is any truth to them at all in being viable replacements to standard lithium ion batteries. By the way, I obtained this tester from Lazada. Someone should sell this in Amazon. You can ro an image search with Google and Amazon to find this tester. Cost me around $5 only. Can be used also to test powerbanks, which often fail to live up to their advertised capacity.

Battery works
