The first 2 months it was like new. It lasted a long time. In the third month and after, its performance dropped sharply. Maybe the summer heat is to blame? In general, the phone heats up quite a bit in the summer when I use it; this always happened with any device

So far it seems to be working well. At least it works much better than the original one I had bought at twice the price, which from the very beginning had problems with charging and battery life and was therefore replaced by this compatible one. I believe that the store selling the compatibles plays a big role. Some stores sell faulty originals and some stores sell reliable compatibles.

It is probably a copy of the original as the labeling of the elements is similar but not identical and printed more faintly... Like new, it lasts longer than the old original which after 4+ years had given out but it is nothing like the original when it was new.

After 20 days of use, it was observed that it has approximately 30% less battery life compared to the old one (2 years old).
