Micro-surfaces on a smart bracelet are almost inevitable when you use it. Owners often look for ways to remove scratches on the Xiaomi Mi Band 5 to restore the original gloss and transparency. The problem is relevant, because this model has a larger screen, which is more susceptible to mechanical stress.
In this detailed guide, we will discuss effective surface repair techniques, and prevention techniques, which work and which can cause irreparable damage to the tracker's polymer coating, and it is important to understand the difference between surface scuffs and deep chips.
Before you start to act, you need to assess the extent of the damage. Light plaque or spider web can be eliminated at home, while deep furrows require more serious intervention or replacement of the module. Chinese engineers used a fairly strong glass, but it is still inferior in hardness to sapphire counterparts in expensive watches.
Damage analysis and coating types
Xiaomi Mi Band 5 is covered with 2.5D glass with an oleophobic coating that thins over time. Scratches can only touch the top layer of the protective layer, or penetrate deeper, deforming the matrix itself or the glass. Understanding the structure of the damage is key to success.
If the nail doesn't cling to the defect, it's likely that the oleophobic layer is damaged, and in this case, polishing will be great, but when the nail clearly falls into the crack, the situation is more complicated, and you need to fill the void or mask it, because you can't physically remove the material.
It's worth noting that aggressive methods can finally destroy the oleophobic layer, making the screen dull and sticky to the touch. So the diagnosis must be thorough. Sometimes it's better to leave a small scratch than to get a matte spot all over the display.
⚠️ Attention: Deep cracks reaching the sensor can disrupt the touchscreen, in which case polishing is useless and can make things worse by driving abrasives inside the device.
For an accurate assessment, use a bright lamp and a magnifying glass, and at the angle of light incidence, the defects become more noticeable, which will help you choose the right recovery strategy.
Preparation of the workplace and tools
Good polishing requires cleanliness and order. Dust caught between the polishing wheel and the screen will become abrasive and create new scratches, so the first step should always be careful preparation.
You'll need soft, lilaless fabric, preferably microfiber, ordinary cotton-coat discs can leave villi that make it difficult, and you'll also need a degreasing agent, like isopropyl alcohol.
- 🧼 Alcohol wipes or isopropyl alcohol for cleaning.
- 🧵 High quality microfiber fabric.
- 🔦 Bright lamp to monitor the result in different lighting.
- 🧤 Latex gloves so as not to leave greasy marks on the glass.
The work surface should be flat and stable. Do not carry out the procedure on weight with the bracelet in one hand, as there is a high risk of slipping the tool, you should put the tracker on a soft substrate or use a special holder.
⚠️ Warning: Never use acetone or oil-based solvents to clean the Mi Band 5 before polishing.They can eat up the plastic case and the glue that holds the module.
Polishing method for toothpaste
The most affordable and popular method, often recommended in forums, is to use plain white toothpaste, which is effective only for very small, barely noticeable scuffs, and the abrasive particles in the paste act as a soft polyrene.
So it's important to choose a paste without colored patches and gel structure, and we need a classic white compound with either silica or calcium carbonate, and gel pastes are particulate-free and useless for this task.
Apply a pea of pasta to the microfiber and rub the screen in circular motions for 2-3 minutes. Don't push too hard to avoid damaging the internal components. Periodically wipe the screen to assess progress.
Once the procedure is complete, thoroughly wash the leftovers of the paste with water and dry the device. This method is safe, but do not expect a miracle: deep scratches it will not remove, only slightly mask them, smoothing the edges.
Use of professional polishing
For more serious cases, there are specialized products, such as polymers for plastic and glass, which contain larger abrasive particles and chemical components that fill microcracks, such as Displex or similar printing products.
The application process requires care, and it's applied to the fabric, not directly to the device, so that the fluid doesn't leak into the gaps between the screen and the frame, and the movements must be smooth, without jerking.
| Remedy. | Type abrasive | Efficiency | Risk of damage |
|---|---|---|---|
| Toothpaste | Soft (carbonate) | Low. | Minimum |
| Displex Display Polish | Medium. | Medium | Medium. |
| Pasta Goya | Chromium oxide | Tall. | High-pitched |
| Diamond paste | Diamond baby. | Maximum | critical |
When using strong reagents such as GOI paste, you need to be extremely careful: it can leave a greenish hue or completely destroy the oleophobic coating. GOI paste is only suitable for glass and requires subsequent thorough cleaning, as it is toxic.
The best way to use specialized polishes for smartphone screens is to use them in a way that is designed with the features of modern displays and does not contain aggressive components.
Masking defects with protective films
If the polishing didn't work, or you're afraid of damaging the device, the best way to do that is to camouflage it, and if you're using a hydrogel film or a quality glass, you can visually hide small defects.
The principle is simple: the adhesive layer of the film penetrates the microcracks, filling them and making the scratch invisible to the eye. The light is refracted differently, and the defect ceases to be visible. This is the safest method.
☑️ Selection of protection for the screen
Hydrogel films are preferred for the Xiaomi Mi Band 5 because of the curved edges of the screen (2.5D). Conventional tempered glass may not stick around the edges or unstuck over time. The film fits the shape perfectly.
Before the sticker, be sure to wipe the screen with alcohol. Even one speck of dust can create a bump that will interfere with swipes. If the scratch is deep, you can drop a drop of transparent nail polish or special UV glue into the recess before the film sticker.
💡
Use UV-glue for hydrogel films only if you are sure of the tightness of the bracelet body, otherwise the liquid can get inside and damage the electronics.
Prevention and proper care
The best way to fight scratches is to prevent scratches, prevent them, prolong the life of your gadget and keep it look good, and regular care takes a minimum of time, but gives excellent results.
Try not to put the bracelet down on hard surfaces. Keys, coins and sand in your pocket are the main enemies of glass. Sand, consisting of quartz, is harder than glass and leaves ineradicable traces.
- 🛡️ Put a protective film on immediately after purchasing the device.
- 🧼 Wash the screen with a soft cloth after exercise to remove sweat.
- 🚫 Avoid contact with aggressive chemicals (household cleaning products).
- 🏊 Wash the bracelet with fresh water after the pool (chlorine destroys the coating).
Sweat and fat from human skin also contribute to the degradation of the oleophobic layer. Regular cleaning with a wet wipe (without alcohol) will help keep the screen smooth.
💡
A timely sticker of high-quality hydrogel film is the only 100% way to keep the Xiaomi Mi Band 5 screen in perfect condition without the risk of damage when polished.
