Galaxy A51 Battery,Upgraded New Battery Replacement for Samsung Galaxy A51 SM-A515F SM-A515F/DS,EB-BA515ABY with Professional Replacement Tool Kits

Came in a small packet. Just as shown in the description. I haven't installed the new battery yet will come back to give a better review to say it is working.

Comes with no instructions but compared to another battery kit I ordered and returned, everything you need is included. There are plenty of YouTube videos showing how to change a battery on the Samsung A51. The hardest part is getting the back off. Applying a bit of heat with a heat gun helps and gently start over the SD card. The frame will flex enough there to get the included black pry tool under the backing. The other hard part is getting the battery out. I applied heat and used another screw driver to gradually ply at the corners. And before you close it all back up, make sure the camera lenses and their clear cover are clean. A speck of dust or something got in on one of my lenses. Luckily not right in the middle. Just be patient. I used the included adhesive but not too much of it. It was totally done in under two hours. Right off, the battery was at 78%. I charged it to 100% and I've left the phone on all night running it down for the first full charge cycle. Still have 17%. Before, the phone wouldn't last three hours of use. But an unexpected improvement is my phone is fast! So much faster. The processor must have been throttling down because of the degraded battery. My phone's over four years old. I'll either use it a few more years now or keep it as a spare when I buy a new phone. Well worth it. ***Update: It's been just shy of a full year and this battery is still performing as well as OEM. In fact, once it broke in after a few months, it started lasting even longer. Pretty incredible, I've now had this Samsung A51 for 5.5 years. Other than the normal keyboard screen burn, I have no desire to replace it. Along with this battery replacement, I highly recommend backing everything up and doing a full factory reset. I did and it runs like new and it truly lets the phone calibrate to the new battery. Also, every once in a while plug it into your computer USB, hold the power and volume up button simultaneously bringing up the system menu and clear the cache. After years of paying $800 for phones, and $100/month for AT&T "Unlimited Data", I discovered I'd never used more that 9GB any month ever. I bought this phone for about $200 in 2020 and pay Mint Mobile (On T-Mobile's network) $240/year for 15GB/month. Smart phones and service went from a monthly headache owing AT&T for the hardware to a non-bill.

Good

Everything worked as advertised

Battery dies very quickly. Much less hold than the original OEM. I bought it in March, had it installed and for example today I pulled the cord at 100% at 8:30 am and have been using it. It's 9:45 a.m. and I'm at 55% already.

it worked just fine!
