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

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.

Good little kit but unfortunately the battery did not hold the charge and the phone will only work when plug into the charger.

This "Dymicbit Galaxy A51 Battery,Upgraded New Battery Replacement for Samsung Galaxy A51 SM-A515F SM-A515F/DS,EB-BA515ABY with Professional Replacement Tool Kits" sat around for a week until I found the how-to videos on Youtube. I've changed batteries in phones before,but this model of phone is a challenge as you're not just opening a panel and popping in a new battery. Once I felt comfortable to take the phone apart it went pretty quickly. The battery charged and the phone works fine. I don't know how long it will last,the original battery lasted less than two years. I will probably buy again when I need it,but I would have appreciated instructions coming with the kit.

Complete and easy to perform the the repair from various videos.

We need more time to follow-up on the duration/capacity of this lithium cell. Installation is actually quite easy, all tools needed are included & simple YouTube videos work wonders, will update this review if any issues arise otherwise take a look @ my pictures, a pretty cool task!..
