"Bought this battery replacement for my wife's iPhone Xs. Battery was fine it worked as intended and have no issues. Taking away 1 star because the adhesive that goes on the back of the battery was not the same style apple uses. And the there was no instructions on how to use the adhesive. But other than that it's fine and worked."

This is a good PSP Slim battery, locks in the place just like it's supposed to perfect fit. Took a couple hours to fully charge on a OEM PSP charger and seems to hold a charge really well so capacity-wise it's on par with the OEM battery if not a little better. It's the same thickness as the original OEM and super easy to install did not come with any instructions but none are needed. Great deal for a nice PSP battery.jamie w

Nice battery replacement kit, included all tools and necessary components, instructions are clear and had some good advice as for a few things i did not know about. Instructions are kind of lacking on the re-assembly part but nothing YT cant fix. In my opinion, outstanding value for the money, you cant beat it. Definitely can tell the difference from the factory battery, Make sure to follow charging instructions for first few charges (included in instructions)amazoniac

Got the old PSP working again - new battery made all the difference. What a surprise to see it boot up like that.This fresh 7800mAh cell fit right into my aging PSP 3000.Right away, the fit felt just right. Same dimensions as the old battery - slipped smoothly into my PSP 3000, no struggle at all. Check first, though - only works with PSP 2000 or 3000 models. Says PSP 2000 on it but it fit right in my PSP 3000.A hefty 7800mAh pack makes all the difference. Noticeable gains in playtime show up right away, while idle life stretches far beyond what my old cell could manage.Heat stays low, even while plugging in or playing long sessions. Overheating is not an issue.One full week of regular charging later, things still run just as strong. When your PSP 2000 or 3000 dies too fast, try this swap instead of tossing it aside. It is a direct fit, not too thick not too thin. Best value replacement battery I could find that had great reviews. Give it a try!babynena

TLDR: Good battery, good capacity, charges well and holds charge, easy to install, flex is a little thinner but connects well, great value for money, same thickness as OEM, solid but a little less stiff. Decent sturdiness. Kit is not that great, but have my own tools anyway.The phone holds a charge much longer than before, and I’m no longer watching the battery percentage drop throughout the day. The kit included the basic tools needed for installation, which made the process manageable as long as you take your time and follow a guide. Once installed, the phone powered on normally and charged without any issues. What I like most is the improved daily usability. I can go through regular tasks like messaging, browsing, and media without needing to top up constantly. The battery has been stable with no overheating or sudden drops, and it feels like the phone has a second life instead of being tied to a charger.Great battery!What Customers Talk About
