简介
本指南说明了如何卸下和更换三星盖乐世 S20的电池。
用强力粘合剂将电池固定到位。必须使用高浓度（超过90％）的异丙醇才能使粘合剂软化并释放。
“如果电池膨胀，如何处理膨胀的电池；请采取适当的预防措施，请勿加热手机。
为安全起见，在拆卸手机前，请使电池放电至25％以下。如果电池在维修过程中意外损坏，则可降低发生热危险的危险。
你需要更换粘合剂才能完成此维修。
你所需要的
-
-
将吸盘套在手机背面，并尽可能靠近左边缘的中心。
-
用强大的稳定力拉动吸盘，以在后盖和框架之间形成一个间隙。
-
将三角撬片的尖端插入间隙中。
-
你也可以尝试在接缝中滴几滴高浓度（超过90％）的异丙醇，以帮助松开粘合剂。
-
-
-
-
-
在框架和电池边缘之间的间隙中使用高浓度（超过90％）的异丙醇。
-
使用酒精时，请倾斜设备，以帮助其渗透电池下方的粘合剂。
-
涂抹酒精后，继续向各个方向倾斜手机两到三分钟，以帮助酒精进一步渗透。
-
将新的替换零件与原始零件进行比较——在安装之前，你可能需要转移剩余的组件或从新零件上取下粘性衬板。
要重新组装设备，请按逆序执行上述步骤。

I had a huge amount of difficulty removing the battery during this repair. The adhesive is really strong, the suction cup doesn't stick to the battery very well and if you lever it out you run the risk of puncturing the battery. It's also really difficult to pull up on the battery while holding the phone down, especially because you want to avoid touching the circuits.
Eventually I succeeded and everything seemed to work but the next day the phone wouldn't switch on. I think maybe the adhesive remover got somewhere it shouldn't have. If I could add something to this guide, it would be "once battery is removed, allow phone to sit for 30 mins to ensure all adhesive remover has evaporated". If I was allowed a do-over I would try to heat the adhesive instead. Or use the string trick. I'm switching to an iphone now because apparently they don't glue their batteries.
Good point! I would suggest to use pure isopropyl alcohol and not something below 99%. The residual water might be not much but still there is a slight chance of it getting somewhere inside. Also the 99% pure alcohol evaporates much faster and leaves no traces. Apple batteries are also glued in with adhesive. What apple does right are the pull-strings to remove the sticky tape between chassis and battery.
Followed every step and managed to complete it but after a couple of minutes the phone screen stopped working and turned black.
I'm pretty sure that happened because the isopropyl alcohol went through the phone into the screen through the gap right under where the battery seats.
If you attempt this at home be aware this might happen, so disconnect the display too or look into using a different method for removing the battery.
I don't think this repair is worth attempting. I also killed my screen with this one, similar to the two commenters above. Whether it was isopropyl alcohol getting into the LCD or whether it was some issue with flimsy connectors I don't know. I was super careful and I've still bricked it, so I'd rate this repair as 'too risky'.
