Keeps oud old phones going...

I now use this in my 2017-vintage Samsung Galaxy J3 Luna Pro smart phone (SM-S327VL). Yes, the phone is "old" now, and only accepts Android 6 as its latest OS. But it's always been great that this phone is one of the extremely rare ones with user-replaceable batteries (and so EASY to replace, at that). I've been though 4 batteries so far over the years. This one is billed as having greater capacity, and I now believe it. I was careful to follow the suggestion to charge it FULLY and discharge it FULLY (to zero) before charging again, a total of five times. This is said to condition the battery chemically to maintain its long life and full capacity. Previous batteries seemed to last about a full day before running flat. And I'd leave them charging in the phone overnight. This new battery lasts TWO days before it needs a charge, and I will NOT leave it charging overnight anymore: I think that shortens battery life and diminishes capacity. I'll buy a second one of these great new batteries and keep it on hand even if I change ("upgrade"?) Android phones, because I like the Luna Pro so much that I could continue to use it as a "tablet" at home with my wi-fi, or for other purposes. It was my first ever cell phone, is small, and basic. Anyway, this is the best battery for the phone that I have seen or used in 8 years. And I wish all new phones had replaceable batteries (but I suppose that's not a good business-plan for the makers, nor for the repair shops).

My factory phone battery started to deplete quickly after using the phone. However, I didn't want to change phones. This battery works as described. However, I noticed that it doesn't charge to 100%. The one I got charges to 93%, but will last a few days unless using Wi-fi and Bluetooth heavily. May be due to it's shelf life. It's certainly not the same quality as the factory battery, but it will keep your phone going.

I'm going from the old 2600mah original Samsung battery to this one that claims to be 4300 mah. I have no way to know if it's really 4300 mah. All I know is my super old Samsung phone--that I only use for music or as a fancy mp3 player--is up and running again without me having to keep the power cord plugged into it. This battery hasn't blown up my phone yet :) I really have not had it long enough to comment on "longevity" or "battery life". Plus, I'm using it for an ancient Samsung Galaxy. So anything I put in it is going to be better than what I took out of it. I'll re-edit the review if I have problems later on, but right now I am happy to say thank you very much to the company who sold this to me at a very good price.

Replaced the battery in my phone when the phone "was old and needs to be replaced " said the Verizon store. Well same phone is holding a charge ALL DAY LONG STILL! thanks to buying this battery . I'm currently writing this review on the phone that July 2023 I was told had to be replaced. So I didnt haven't spend 500$ on a new phone and the few bucks I spent on this battery has got me over a year of reliable service. I'm so hard on phones it's been dropped from over ten feet into water , out in -10°F weather and hasn't failed or disappointed me in the least bit. Such a great value. Dont hesitate to save yourself a bunch a money.

This battery gets hot. I bought two batteries from one seller before and I bought the third one from this seller and let’s just say this one gets a little bit less high, but it still gets hot and it gets too hot to a point where I can’t hold my phone so I put on the AC to cool it off. I can’t even enjoy this phone without it getting hot while I’m in the car with the car being off. It’s like the battery soaked in heat at this point I don’t know what to do. I don’t know if Amazon batteries are good to purchase so if you’re gonna buy it, it’s on you for me. I’m a return this and get my money back.

Worked well, easy install

This batter was for a 6 year old cell phone. It is a 6 year old, new lithium battery. It's charge powered the phone for two - three days. The price was right, with Prime delivery. I couldn't have found a better deal, in my opinion, all things considered.
