This manual will guide you through the process of replacing a battery in an iPhone 7 and give its battery the power to last as if new.
To avoid damaging the display cables, this manual instructs you to remove the display part from the device. However, if you are willing to risk this, you may skip this part and move directly to the battery replacement part.
For optimal performance after replacing the battery, calibrate the new battery: discharge it under 10% and then recharge without interrupting to 100%.
Opening the iPhone 7 display will compromise its waterproof seals. If you do not replace them, the device will be functional, but no longer waterproof.

Before you begin, discharge your iPhone battery below 25%. A charged battery can catch fire and/or explode if punctured.
Opening the iPhone's display will compromise its waterproof seals. If you don't replace it, your device will work, but it won't be waterproof anymore.
Heating the lower edge of the iPhone will help soften the adhesive by which the display is secured, which will make it easier to open.
Make sure, that the suction cup does not cover the home button, which could cause formation of an air bubble.
Do not move it all the way towards the top edge of the phone, as this could damage the plastic clips which secure the display.
Do not lift the display more than 10° angle as this part is still attached to the rare case by thin ribbon cables, which it could damage.
Be careful not to damage the plastic clips on the top edge of the phone.
Do not attempt to fully separate the display part yet, as it is still connected by fragile ribbon cables.
Tilt the connector cable away from the device, to avoid electrical contact with other parts.
Hold the adhesive tapes straight while pulling them out to avoid them from rolling and twisting. If they stick to something or to each other, they might rip.
Pull the ends of the adhesive tapes using your fingers and one by one pull them from under the battery towards the bottom of the iPhone.
The tapes have a tendency to return to their original length. If it slides out from your fingers, grab it and continue pulling.
Overheating the iPhone may cause battery fire.
Do not use too much force to push and do not slide in the card in the area between the volume buttons, you could damage the cable, which connects it with the motherboard. Keep the card as flat as possible to avoid breaking the battery.
Apply new double-sided adhesive tapes on a new battery and install it into the phone by reversed process.
