I buy battery kit. I follow guide. My computer now has 103% state of health and an extra 3 hours of run time. Perfect.

I’m not sure I would call this guide difficult - don’t let this put you off. If you follow all the steps and go carefully with the adhesive remover (and don’t prod too forcefully with those cards) it should all go smoothly. Much easier than things like replacing iPhone home buttons where there are lots of ways you can make a mess. Great work iFixit for the guide and a very high quality replacement battery. €100 saved.

Done successfully for two phones. The standoff screws were a pain. To remove them I used a sharp knife placed flat into the groove on the screw and unscrewed a quarter turn at a time. The iFixit screwdrivers are not fine enough for that. To reassemble, I held the standoff screws in position with tweezers and rotated the phone underneath it. Great guide.

Done without any problems in 15 minutes using the recommended tools (and the normal suction cup). Good advice not to remove the screen. I propped it up at 90 degrees and left the connectors attached and there was no problem removing the battery. Constant and gentle pressure on the pull tab was enough. Battery working well now and no issues to the screen.

Fantastic guide and good video. Feel justified in buying the tools now as they've already paid for themselves.
