GARBAGE. DANGEROUS GARBAGE.

Finally, there is a reason why this battery, despite claiming authenticity, is so cheap.

After 1 week of use, it started bulging during charging, swelled up, and broke the back cover of the phone.

If I had continued to use it, I am sure it would have caught fire.

I threw it away and replaced it with a truly authentic one, which has been working without any issues for 8 months now.

Completely useless, on the second day of use it immediately drains from 40% to 25% and shuts off! My German friend told me that these batteries, because they are stock and have been sitting for a long time, do not perform well. That's why they cost only 10 euros...

Completely useless. I kept it for a week and then put the old one back on. You should prefer getting the official service pack, even if it's a bit expensive, in order to have peace of mind

Given that I bought it in bulk without its original packaging, I can't even know if it's authentic. Throughout, I haven't seen any real difference from the one I had, but I have a reservation for heavy usage situations where it seems to maintain a higher battery percentage than my heavily used one, which is a sample of a new one.
