XYIRMCYF Battery note 10plus
Very good product.ordered it for my Note 10 plus, work perfectly and I would say easy value for money. At the same time I don't see any changes in the capacity of the battery and how long it takes to run dry

Great product, may have caused strange charging behavior (read desc)
These things last forever, they seem to have issues charging and I don't know if that's just because of my controller but it takes very specific cables to charge my controller now (chromebook chargers, and other high power chargers). My girlfriend's controller does not have this issue so I do not know the cause, just wanted to note it.

I Did It!! You can too!
After watching some YouTube videos (multiple times) I finally pulled the trigger on replacing my iPhone SE (1st gen) battery. It went amazing well! I had a few minor issues: pulling out the adhesive strips (yup, they broke) and the video addressed how to deal with that. With some blow dryer heat and some gentle prying, I was able to get the old battery out. Yay! The other issue was knowing which screwdriver-type tool to use with which screws. The screws are incredibly tiny. Repeat: incredibly TINY. 😕 I’d say the reassemble process took more time than the disassemble time. Those teeny tiny screws were challenging (along with figuring out which tool to use). After the successful reassembly the new battery showed it was 65% charged (out of the box). I went ahead and plugged in the device to fully charge to 100%. GREAT news, the battery has only gone down by 2% after 4 hours. Woo-hoo! With the original battery it would go from 100% to 20% in a matter of 2 hours ☹️. And then from 20% to zero % within minutes. I am so pleased that I now have a reliable device that I use mainly for reading ebooks and for music, plus some random apps that I got for free way back when. And a side note, I’m a female in my late 60’s, and am quite proud of myself for my accomplishment. If I can do it, you can too!

It works and it's cheaper than going to apple.
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.

Cheap price to bring your phone back to life
Great product. For as little as $30 brought my iphone back to life. The replacement process is not extremely complicated, but you definitely need an youtube video for instructions and visualization otherwise it would be easy to mess it up. Battery fits perfectly and plastic film with a new screen glue lines up very well.

Standby 4 days
It standby for 4 days with 20% remaining. There is a trick to install. I snapped in the battery with finger and kept for a day to check without closing the cover. It drained in 24 hours. Then, I pressed all connections firmly with the plastic tool and saw the battery declined slowly. Obviously, loose connection burnt power quickly.

Easier installation than I thought
Amazingly simpler to replace as long as you use correct screwdriver for the bottom screws and then the inside screws. And keep those screws in the order you take them out put them back in. I didn’t have to pull out the glue because the battery was previously replaced by someone who didn’t use glue to anchor the battery in. This gave me enough courage to replace the screen that was wonky now I have a phone that’s like new and battery. Life is excellent.

Worked great for an Iphone 6
As other reviews have mentioned the claimed 13000mAh capacity of the battery is false advertising, the actual mAh is less. It's probably the same as a standard battery for whatever model you getting a replacement for. I didn't see any reviews for a base Iphone 6, but my wife refuses to let hers go and the battery was completely bad and wouldn't hold a charge at all. The swap was very easy and installation was a breeze took me like 10 minutes to open the phone and remove the old battery/screen and then 5 minutes to put it all back together. The phone's battery now is basically back to good as new which is why I'm giving 5 stars despite the false mAh rating as I knew that going in.

It’s been months and all is ok. Have steady hands, no distractions. White background for repair. Do a YouTube and make sure it’s for your phone. Easy to do. Once you’ve done one, you’ll never use service again. Comes with all the tools (which I’ve used for other repairs requiring tiny tools)
