Very good, I've had it for 3 months with a lot of talking (BLUETOOTH HEADPHONES AND SMARTWATCH) and less video-music-internet, it lasts at least a whole day!

It's just fine. You just need to be careful when opening the back of the phone and removing the battery, which is stuck (with adhesive) to the device. Also, it's missing the orange sticker shown in the photo. That's not a big deal, but come on guys... how hard is it to put the correct photo...?

I bought it as a precaution (without actually needing it) only because someone told me that soon I wouldn't be able to find it since my phone model is old. I took it today, still sealed in its box, to have it installed and unfortunately it is broken at the top of the contact, so it is useless because it cannot be installed. So I have paid 30 euros to have a useless battery in my hands even though it is new and unused.

Okay, I knew it wasn't original, but I didn't expect it to die completely in 4 days. Very easy installation, it charged normally for 3 days (not on a fast charger but on a slow one with a few watts). On the morning of the 4th day, with over 20% charge, it suddenly turned off. I put it on the charger and it wouldn't even turn on, just the LED was blinking. I left it on the charger for 4 hours and it didn't even get warm at the back, so it wasn't charging. Fortunately, I hadn't recycled the original one and I put it back to have at least for the holidays.

The battery was not loaded what made us anxious that it wasn't good, but it seems now after almost 1 month that it is an exellent battery!
Thanks!

The duration was worse than the original one I had for so many years, it took excessively long to charge and within a week, as soon as the phone completely discharged, it broke...

Attention, make sure to get from a store that describes the battery as "original" or "service pack". They are usually more expensive... Around 25-30 euros, instead of 15-20 that oem batteries cost.

I bought one that states in its title that it is original and indeed it is, it has the expected capacity and charges at the expected speed.
After a bad experience with an oem battery, I recommend the original one even if it costs 10 euros more.

I changed the factory battery and replaced it with this one because its performance had dropped. I haven't seen any difference in terms of the duration that the old battery lasted compared to the new one. I would say that it is not worth buying

I don't know if it happened to me, but I got a very good battery with a long duration. It needed 3-4 charges at the beginning to settle, but now it's great. Just be careful with my POCO x3, it didn't charge the old one and I thought it was the battery's fault. It wasn't. It was the charging cable that charges the POCO. It's a known issue.

Worst battery, even worse than the old one that was in the phone for 2 years and I had drained it playing games. Fully charged and without using the phone, it dropped from 100% to 84% in an hour and a half. Not even the old one would drop like that, I'm telling you.
