In less than 20 days, the mobile phone started to open and close on its own and eventually completely blocked and never opened again. STAY AWAY!!!

It is a few millimeters larger than it should be. It takes force to put it on and some kind of tool to remove it. I probably got lucky because it doesn't seem to have good quality construction.

It doesn't hold at all and at 30% the phone shuts down on its own. After replacing the battery three times, I finally asked for a refund and kept the original one that came with the phone, which is almost 8 years old and doesn't shut down on its own, it just doesn't last long.

It lasted me 1.5 months (made in Vietnam)! Then it started causing problems with my phone. It kept rebooting and I couldn't even do a hard reset! I watched a video on YouTube and as soon as I changed the battery and put the old one back, it worked fine!

I bought it from a store that had it for 15€.... it didn't have the manufacturing date written on it.... I changed it in 3 days!!! It gives me a second one... I changed it in 3 days!!! I'm getting a third one... all three are the same... I tried them with 3 different chargers... you take it out of the charger and it finishes in no time!!! I definitely charge it twice a day!!! I won't go again to change it!!! I'm tired of doing this job... wasted money...

I have had the battery for about 1 month, it has not shown any signs of wear and tear so far as it discharges within reasonable limits, depending of course on the usage I make of it, because the previous one I had without usage would lose over 20% in 30 minutes. I charge it once a day if I use the internet a lot.

They bought 2 batteries in order to install them in 2 _s5 mobile phones that I have. The result? Pure disappointment. Shortly after, both batteries are worse than the original ones (3 years old) that they replaced. They run out with minimal use.

It drains very quickly and without the use of the internet... its battery, even though I've had it for 3 years, is definitely much better.

Such a product was purchased and within a week it inflated and couldn't hold for even 10 minutes without the charger.

Mediocre performance. Sometimes the phone shuts down, with another spare battery I have it doesn't shut down, so it's the battery's fault

The battery came in bulk packaging, in a small bag, meaning it is authentic and made in Korea, exactly the same as the factory one. No issues with its functionality.

Whatever is written on it, Made in Korea, lasts for 3 months... for me, within a week, as soon as I took it out of the charger, it went from 93% to 2% in 2 minutes... and with minimal use, it needed to be charged during the day... only made in Japan or China, like the one I bought.

I bought a battery to have as a backup for when I run out of battery. The only thing I have to say is that it drained within 2 hours of moderate use, and in order to return it, the packaging must be intact, so it's a hassle

I don't know if it was the specific batteries I ordered, but both of them turned out to be defective!! With the extra battery kit from Samsung, they never fully charged! And they drained very quickly on my phone! On the contrary, the extra battery kit includes a battery in the package and it has proven to be excellent!!! Maybe because it is genuine and packaged. Because all the cheap ones here are bulk (meaning without packaging)!!
