Galaxy S20 FE Battery, [Upgraded] UNKLOU 5200mAh Li-Polymer Replacement Battery for Samsung Galaxy S20 FE 5G SM-G781B G781U G781W SM-A526 A526B/DS A5260 A526W with Repair Replacement Tool Kit

Seemed to take a long time to arrive but installation was swift and simple!

I installed this battery in my phone a week ago. At first it was draining fast, so I looked up how to calibrate a new battery, went through the process of calibrating it twice and now it is running great in my phone.

I had high hopes for this battery. Did the 3 cycle total drain and then recharge as recommended. New battery dies in 9 hours. I'm probably going to put the old battery back in and return this one. Waste of time and money.

There was no manual or installation guide included, although the description said there would be.

The hardest step to installing this battery is removing the glued back. Follow the YouTube videos. I used a heat gun on low heat. A hair dryer on high would also work. I put the phone face-down on a kitchen hot pad and used a 2nd pad to hold the phone. I heated only a third of the bottom starting near one corner. I used a triangular blade Xacto knife to gently cut the heated glue. Once I got the point (only the pointed tip) of the blade under the cover I continued heating toward the corner until I could slowly drag the knife tip into that corner. Then I pried the back enough to insert the plastic cutting tool. I removed the knife and heated the remainder of the bottom; inserted the 2nd cutting tool and dragged it into the other bottom corner. From there it was heat - cut in steps.Once the back cover is free the rest is easy; follow the videos. I'm currently conditioning the battery (drain to 0; charge to 100; repeat). I added 2 steps prior the reassembling: clean the camera lenses and flash as well as the lens protector inside the cover; use DustOff or pure air to blow out the phone and cover. I did NOT remove the residue glue and found that it resealed the cover. A little heat would likely have helped but I use a case which keeps the cover tight.

The battery must be charged twice a day for 1.5 hours on fast charge. Complete garbage. Bad product.

It works for my cell watch out for the battery in the phone held down with sealant a bear to get out.

Doing good so far, but doesn't seem like a upgrade over original. Better than a bad battery, but about the same as original. Screw driver broke.
