It's worth the money. Always authentic batteries, don't take the risk. The old authentic battery had 'swelled' after 8 years. So the replacement was very easy, with some instructions from YouTube. It cost me 1/3 of what the repair shops were asking. It's the authentic battery, and it gave new life to my old (8-year-old) phone. It lasts as long as Samsung says it should and the phone doesn't heat up.

The battery is unacceptable, the phone shuts down on its own before even reaching 50% and quite quickly. When you start charging it again, it tells you it has 0%.

I changed the battery because it died after 3 years, which is understandable. I put in a Chinese 4000mAh battery which turned out to be 3000mAh according to the accubattery, and the battery life decreased even more. The phone was holding up much better, but I decided to change it and put in this one as the original for better performance. Well, it doesn't even last 4 hours without usage. It's really a shame. Now I have to find a good battery. They will force us to change our phone.

It is the worst thing I have bought. It lasts about 4 hours, whereas my genuine one lasted much longer. I decided to change it for something better. I will eventually have to change my phone because of the battery

I bought two batteries with a 6-month difference in purchase, and both batteries had the same performance as the factory one that came with the phone, which lasts around 4 hours without power saving. In conclusion, if you want to have the best battery, it's better to go to an official Samsung service. You will pay more money, but you will know that the battery will last as long as a brand new one for the phone.

It's like I never changed the battery. Worse than the one I had before, which was two years old. The phone lasts a maximum of 5 hours with power saving mode enabled
