简介
本指南将展示如何拆卸并更换三星Galaxy S20的电池。
电池通过强力粘合剂固定。需使用高浓度(超过90%)的酒精才能软化并清除该粘合剂。
若电池出现鼓包,请采取适当预防措施,切勿加热手机。
为保障安全,拆机前请将电池电量放至25%以下。此举可降低维修过程中电池意外受损引发危险热事件的风险。
您需要准备替换用粘合剂才能完成本次维修。
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。
-
-
-
在这个步骤中使用的工具:Tweezers$4.99
-
-
将吸盘吸柄置于电池中心位置。
-
一手将设备顶部和底部抵住工作台面,另一只手用力向上拉吸盘手柄。
-
该粘合剂需要时间和反复拉扯而非强力才能松动。每次以稳定力度持续拉扯吸盘15秒。
-
若电池仍未松动,请在顶部、左侧及右侧边缘各滴1-2滴异丙醇,等待一分钟后再次尝试拔出。
-
当电池开始从设备上抬起时,请继续执行下一步。
-
将新更换部件与原部件进行对比——安装前可能需要转移剩余组件或清除新部件背面的粘合剂。
重新组装设备时,请按上述步骤的逆序操作。
请参照this guide 执行电池循环重置,并calibrate your newly-installed battery。
请将电子废弃物送至R2 or e-Stewards certified recycler处理。

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.
