简介
使用本指南更换 Galaxy A70 中磨损或没电的电池。
如果你的电池膨胀，采取适当的预防措施。为了你的安全，在拆卸手机之前，将电池放电到 25% 以下。如果电池在维修过程中意外损坏，这会降低发生危险热事件的风险。
重新组装设备时，你需要更换粘合剂来重新连接组件。
你所需要的
-
-
-
在电池底部边缘的缝隙中滴几滴除胶剂或高浓度（90% 或更高）异丙醇。
-
向上提起手机底部，使其朝后置摄像头的方向倾斜，让粘合剂去除剂在电池下方展开。
-
让粘合剂去除剂渗透电池粘合剂至少 1 分钟。
-
如果可能，请在安装新粘合剂和重新密封之前打开你的设备并测试你的维修情况。
使用预切胶粘剂或双面胶带固定新电池。为了正确定位，请将新粘合剂涂在旧粘合剂所在的位置，而不是直接涂在电池上。将新电池牢固地按入到位。
要重新组装你的设备，请按逆序按照这些说明进行操作。用异丙醇 (>90%) 清洁相关区域后，在必要时涂抹新的粘合剂。
为获得最佳性能，请“校准新安装的电池”：将其充电至 100% 并继续充电至少 2 小时。然后使用你的设备，直到它因电池电量不足而关闭。最后，不间断地将其充电至 100%。

How to remove the adhesive on the midframe ? Can I immerse it in alcohol?
Hello Ripple Blink, I'd recommend first removing adhesive remains by rolling them up on the tip of a spudger or scraping it off with the flat end of a spudger. Afterwards, you can use a lint-free cloth (or coffee filter) with a bit of isopropyl alcohol to clean the adhesion surfaces. See the first two steps of "How to Use a Pre-Cut Adhesive Sheet" for more information. Hope this helps!
My dad replaced the battery in his A70, however he didn't wait for the alcohol to dry out and instead started using the phone. This led to major issues with touch disease and a glitchy screen. Once he had the sense to wait for the phone to dry it started working, however the fingerprint sensor has stopped working. Anyone know why? Could the sensor be damaged?
Hello Ibrahim Anser, normally the fingerprint sensor shouldn't be impacted by the steps detailed in this guide. Have you tried deleting the fingerprint data, restarting the phone and reregistering the fingerprint or does the fingerprint sensor not accept any inputs? You could also try using the Samsung Member app for hardware diagnostics of the fingerprint sensor. If those approaches fail, you could try checking if the fingerprint sensor cable is seated correctly on the daughterboard or if there is an issue with the connector (moisture or bent pins). As a last resort, you could remove the fingerprint sensor itself to check for moisture or other issues. You would need a Phillips screwdriver for that. Hope this is helpful!
