Upgraded 4050mAh Li-Polymer Replacement Battery for Samsung Galaxy S7 Smartphone

TWPiteo: This is a Galaxy S7 replacement battery of 4800 milli-amps which boasts a longer run and standby time as compared to the original 3000 milli-amp battery which is several years old. I find this new battery drains almost equally as quickly as the much older and 1800 milli-amp weaker original battery.
*** More importantly ***
I find that when viewing videos this replacement battery "very quickly" generates much more heat than the original battery. I am operating the phone without the rear cover installed so as to locate the heat source which proves to be the battery.
New battery installed for only 2 weeks therefore I cannot rate its longevity. Not impressed with battery. .

Angel C: I got this for my s7 since it's an old family phone and still good I decided to set it up. Getting the old battery out was an adventure, s7 has glue and glue everywhere even on the battery, my old battery was squished into place and bent slightly so getting it out sucked as my personal metal tool made sparks against the batteries, I used the included angle tool and some strength to eventually get it out.

The tools weren't completely useless, screwdriver helped, I really needed more than one guitar pick as I only had one and chewed through the edge very fast, I used my own knife to open the phone also the provided tools were no help. The battery went in easy and worked immediately, I have tested all parts of this battery and it is no where near the 4800 capacity, multiple manual measurements I have done with software say it's about 3200 capacity, no higher. It's definitely good since it charges as fast as the old one and the charge holds, but still the s7 will drain 25% in about 10-15 mins, the old one was draining over 1% a minute, but that's mostly the old firmware, still though loosing almost 1% a minute even with the new battery sucks. Battery life with reasonable use...

tony: What a freaking pain it was to remove the back glass panel. The little suction cup and attached ring is too weak and deforms too easily so it was useless. I had to find some other suction cups to use and a much bigger key ring. I recommend heating near the charging port as shown in some videos, that's the easiest way to start. Forget the edges, I tried several times and it was impossible to open. Finally got it removed after several heating attempts, but the foil on the back side of glass panel started to peel away because I didn't apply enough heat on the rest of the edges, so it looks like crap now.
Next was pain point #2, the original battery was very difficult to remove.. There isn't much room to stick the wedge tool to lift up the battery. I ended up damaging the edge of the battery with all the pry attempts and it started smoking and melted edge of the pry tool. Lesson learned, make sure you fully discharge the battery before you attempt this.
The hard parts done, replaced battery, powered up at 57%,.. let it set for a few mins, down to 52%. Will see how it fares over next couple of days. Overall, this was a medium to difficult replacement. Very concerned that this...

ZiggyZiggy: Battery swap on the Samsung Galaxy S7 wasn't impossible but wasn't fun either. The tools included were useful but a second guitar pick made working around the back cover much easier.
After the battery was installed I promptly charged the device to 80%. It arrived with a 52% charge.
I've used my phone for the last couple of days since replacing the battery and it now functions like it used to when it was new.
I am very satisfied so far with the replacement battery's performance...
Although I haven't witnessed the 3600mah rating yet. The application I use to measure the battery capacity is called AccuBattery. You can find it in the Play Store.
There are cheaper replacement options out there but I believe the price sometimes represents quality level of materials used. I'm not sure if it's the case with these batteries or not but, hey, what's $10?
I just wanted a quality battery replacement for my phone I use daily. I believe I got what I was looking for.

Update: January 31, 2020
Been using the phone daily. Have been kind of let down with the dwindling capacity. Originally right after initial replacement the new battery showed about 3000mah capacity. Now...
