Having the tempered glass broken and the battery that runs out after 10 seconds, I proceeded to replace them.
Specifically for the battery, I opted for a compatible Chinese one that seemed to me of good quality and above all of the recent production, a 3000 mAh XXLLHAM, of the Li-Po type, compatible with Huawei Honor 8, Huawei Honor 9 Lite, Huawei Nova 2 smartphones. Lite, Huawei P Smart, Huawei P10 Lite, Huawei P20 Lite, Huawei P8 Lite (2017), Huawei P9, Huawei P9 Lite, Huawei Y6 (2018), Huawei Y6 Prime (2018), Huawei Y7 Prime (2018), Huawei Y7 Pro (2018), Huawei Honor 7 Lite and in general for batteries with code HB366481ECW.
In current smartphones, most components are glued; therefore, to disassemble them, you have to loosen the glue's grip, for example, by using a hairdryer, but being careful not to overdo the heat, to avoid melting the plastic parts.
With the plastic pick, present in the tool kit supplied with the battery, working along the edges of the cover, but without exaggerating the pressure, I separate the rear cover from the body.
With the Phillips screwdriver supplied with the tool kit, I unscrew the two small screws to remove the protective plate of the battery connector.
I unplug the battery connector.
The battery is attached to the body with a double-sided adhesive; then, being very careful, I remove it by using the small plastic lever and the pick, both always supplied with the tool kit.
The adhesive still has good adhesive power; then I apply the new battery directly to it, connect the connector and screw the protection plate back on.
Before completing the reassembly, I check that the smartphone turns on and that the battery is working correctly.
Indeed, everything works smoothly and the battery is already about 50% charged.
Working carefully with a cutter and an old toothbrush, I remove and clean as much as possible the residues of the old glue to ensure the best adhesion between the components.
To glue smartphones, special glues are sold which in practice simply have a spout of a suitable size to do precision work; so knowing the goodness of Bostik Superchiaro mastic type glue for these types of materials I put some in a syringe to which I removed the part of the steel needle in such a way as to be able to perfectly dose the glue along the edges of both parts to be glued.
After waiting about 15 minutes, as indicated in the glue instructions, I join the two parts to be glued with a short but intense initial pressure, I wrap the smartphone with a cloth and put it under pressure for about 24 hours between two pieces of wood held by two clamps.
I check the perfect seal and remove the dry glue residues.
With one of the various apps available to evaluate the state of the battery charge, I verify that the current estimated battery capacity is about 2900 mAh; therefore perfectly in line with the data declared by the manufacturer and equivalent to the original, as well as of good general workmanship.
Since the battery replacement was successful, I proceed to apply the new tempered glass.
The first thing to do, of course, is to remove the old glass.
I initially tried to remove it using the pick, but the glass shatters; so I decide to use dental floss to slide under the tempered glass which will gradually lift and detach safely without causing any damage. If the adhesive is particularly strong, you can try to loosen it with a jet of hot air from a hairdryer.
I clean the display with a vacuum cleaner, with the damp cloth supplied with the kit, and remove the residues of lint and dust with the adhesive also supplied.
To apply the glass as accurately as possible, it is advisable to use the supplied adhesives in such a way as to fix the position longitudinally and have a grip on the glass on the opposite side to easily remove the protective film of the adhesive and reposition the glass that will adhere perfectly entirely by giving a simple push in the center.
Any bubbles will disappear after a short time, perhaps by applying even a slight pressure to the affected areas while cleaning the glass with the second dry cloth supplied.
