Stay away from these batteries. I had bought one for an old S6 and within 6 months it became like a balloon, it also damaged the screen of the phone. Fortunately, the office didn't catch fire, or we would have had more problems.

Stay away from this battery, guys! Within 3 weeks of the phone shutting down at 50-40%, I noticed a crack on the back of the phone (battery cover). Eventually, the entire cover opened up and the swollen battery was revealed.

Unacceptable battery, probably of second quality because I can't imagine a genuine Samsung battery dropping to 85% right after being charged and not lasting a day with moderate use. It's a shame for the effort and money spent, because the one it replaced was better even though it was 4 years old!

Unacceptable battery. From my first measurements, it showed only 1650mA. I contacted the store and they told me that the measurement was to blame, not the battery. Of course, that was not true. From the beginning, you realize that you are very close to the performance of the worn-out battery that you wanted to replace. In the 6-month period, the battery completely failed. It is not worth even its small cost and especially not worth the process and expenses of replacement.

I did not believe in the misfortune of others and bought an allegedly authentic product from a reputable store. On the 3rd charge, it started malfunctioning. After charging to 100% and unplugging the charger, it immediately drops to 98% and within 5 minutes, it goes down to 86%. Then, it slowly decreases to 0% and functions like a new one. Essentially, it is a battery with only 86% of its nominal capacity...
Basically, it's a waste...

I didn't see almost any difference from my old battery that I thought had a problem because it discharged very easily! I don't know if it's the new battery or the power management of my phone!

Terrible... Worse than the original as my friend below says! And they don't provide the service to take it for a 60 euros change! and installation! I put the old one back again! The battery was gradually dropping on its own

The battery arrived charged at 7%. When batteries are inactive, they should be around 60% charged. So, measuring the health of the battery when I installed it in the device, it showed 71%. That means it had roughly 30% damage. The previous battery I had on my device had the same amount of damage. I opened the Galaxy S6, which is difficult to open for nothing, and I paid for a faulty battery. Before purchasing batteries, ask for the manufacturing date. If the supplier sends the battery with such a low charge and it stays at that level for 3-4 months, then it gets damaged. Buy batteries with a very recent manufacturing date.
