Galaxy S4 Battery, Upgraded 3200mAh Li-ion EB-B600BE Replacement Battery for Samsung Galaxy S4 AT&T I337,Verizon I545,Sprint L720,T-Mobile M919,R970,I9500,I9505,LTE I9506 [3 Year Warranty]

I don't know much about batteries. I do know my phone eats them up. I haven't had this one long enough to evaluate battery life, longevity, or value for the money. It seemed reasonably priced and the product description gave me charging instructions that no other battery bothered to include. That was the basis for my decision to buy.

Short battery like is due to the s4 itself and not part of the battery design.

I bought two of them because of a review that said spend a few bucks more an get a better battery. They were no better than the two year old battery that I was replacing.

Longer battery life on phone. Don't have to charge as much.

Wife's phone needed a new battery. Price was right charge time left a lot to be desired.Had to buy a another battery.

Dont waste your time or $$ wont hold a charge for 1 day of little use 50 % by 5 pm or so and cell down to 15% by 8 pm with no use on the cell . 3 year warranty lol never respond to me after a few emails So guess he wont mind - feed back

I have not used this that long to be able to reliably rate it, but thus far it is working admirably after about a month.

The battery drops it's charge in only 4 hours.
