Is your battery running out way too fast? Are you forced to recharge your S7 more than once a day? This guide will show you how to remove the tired old battery in your S7 and replace it with a new one.
Note that the video guide recommends removing the SIM card. This is not necessary, but won't negatively affect repair if you do remove it.
Before disassembling your phone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
If your battery is swollen, take appropriate precautions. Do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.

-
Apply a heated iOpener to a long edge of the phone for about two minutes.
-
-
-
When the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge.
-
Lift on the suction cup and insert an opening pick under the rear glass.
-
-
-
Once you have the pick firmly inserted into the glass, reheat and reapply the iOpener to soften the adhesive.
-
-
-
Slide the opening pick down along the side of the phone, separating the adhesive.
-
Leave the pick in place and grab a second pick as you proceed to the next step. Leaving the pick inserted can help prevent the glue you just separated from re-adhering.
-
-
-
Repeat the previous heating and cutting procedure for the remaining three sides of the phone.
-
Leave an opening pick in each edge of the phone as you continue to the next to prevent the adhesive from resealing.

If you're cleaning the midframe surface with isopropyl alcohol, be careful not to get any alcohol on the wireless charging coil. The coil coating will break down if it contacts alcohol.

-
Insert the tip of a spudger into the small notch on the left side of the antenna assembly, and pry the assembly up and out of the frame.
-
Remove the antenna assembly.
-
-
-
Use the flat end of a spudger to lift the charging coil assembly out of the phone.
-
-
-
Use the flat end of a spudger to disconnect the battery connector.
-
-
-
Apply 1-2 drops of high-concentration (>90%) isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.
-
Alternatively, prepare an iOpener and apply it directly to the battery.
-
Apply the iOpener for at least a minute to soften the battery adhesive.
-
-
-
Use an opening pick to pry up the battery from the bottom using firm, constant pressure.
-
-
-
Slide an opening pick up the side of the battery to break apart any remaining adhesive.
-
Lift the battery out of the case.
-
If you used isopropyl alcohol, wait ten minutes before installing the new battery to allow the alcohol to completely evaporate.

After this is it still waterproof?
In theory, if you applied the replacement adhesive 100% correctly, it will retain its water resistant properties. However, I would never deliberately expose any device to water, as you can never be completely sure that all the seals are perfectly intact.
That is actually covered in the video. Did you actually watch it? If water resistant is important to you then what you would do is purchase new gasket material so that after you have opened up the phone and removed all the existing gasket you would apply the new gasket and then finish up and re-seal your phone. As to how water resistant it is after re-sealing the phone all depends on how careful you are and how exact your work is.
Sooooooooo why exactly did Samsung make it impossible to open the phone?
Because screws are unsightly :P… and repairing your old phone makes you not want to buy a new phone.
