Phone care basics
Mobile care and repair: what you can do yourself
Mobile care and repair starts with small fixes you can do at home: a clean charging port, a battery that stays cool, a case free of grit. Here is the short routine that keeps your phone in shape, and how to tell when a repair is better left to a shop.
The weekly routine
You don't need special kits. A microfiber cloth, a little water and five minutes a week cover almost everything.
- Wipe the screen. A dry or barely damp microfiber cloth lifts oil and dust without scratching.
- Take the case off. Sand and crumbs collect behind it and rub the back and edges.
- Look at the charging port. Lint packs in over time and causes loose or slow charging. Shine a light in before you blame the cable.
- Keep it out of the heat. A dashboard or a sunny windowsill ages a battery faster than daily use.
- Charge in a cool spot. Charging under a pillow traps heat. A table or shelf is better.
- Back up your data. Do it before a repair, a trip or a new screen protector goes on.

When to get help
Some problems are not worth a home fix. A battery that bulges, a phone that gets hot while it sits idle, or a smell of burning plastic all mean you should stop using it and take it to a repair shop. The same goes for water damage: switch the phone off, don't charge it, and let a shop open it up.
For everything else, small habits do most of the work. A phone that is kept clean, cool and backed up lasts longer, sells for more and is easier to repair when something does go wrong.
Your phone touches your cheek on every call
Most of the phone care routine above is about the screen, and for good reason. The glass collects oil from your fingertips, plus sweat and any makeup or sunscreen from your face, which is why it smears so fast. Then every call puts that same glass flat against your cheek, often for many minutes, with your hand pressing it in place.
That is repeated contact on one patch of skin. MedlinePlus lists excessively touching, resting on or rubbing the skin as something that may make acne worse, and it names greasy cosmetics as another (MedlinePlus: Acne). A phone brings both to the same spot.
| Phone habit | What it changes for the skin |
|---|---|
| Wipe the screen every day | Less oil and makeup on the glass |
| Earbuds or speaker for long calls | No pressure on the cheek |
| Notice where the spots are | Spots only on your phone side point to contact |
If spots keep showing up on the side you hold the phone to, the guide below on cheek acne, from cheekacne.com, explains the other causes and what treats them.
Cheek acne
Cheek acne on one side only usually comes from your phone or the pillow you sleep on, while both cheeks flaring before a period lean hormonal. Small bumps after a new cream or makeup point to the product.
Hands, hormones, heavy moisturizer or sunscreen, and anything that presses on the cheeks can all set off breakouts; salicylic acid or benzoyl peroxide treats most of them.
Common Causes of Cheek Acne
| Trigger | What it looks like | Fix this week |
|---|---|---|
| External Contact & Friction | ||
| Phone held to the cheek | Spots on the side you hold your phone to | Wipe the screen daily; use earbuds or speaker |
| Pillowcase | Spots on the cheek you sleep on | Fresh pillowcase at least weekly; flip it midweek |
| Hands on the face | Spots where you rest your cheek or chin in your hand | Hands off; don't squeeze or pick |
| Mask or chin strap | Red bumps where the edge rubs, cheeks and chin | Gentle skin care, shorter wear, a fresh mask |
| Pore-Clogging Products | ||
| Makeup and brushes | Small bumps and blackheads where makeup sits | Take makeup off every night; wash brushes |
| Heavy moisturizer or sunscreen | Breakouts that began after a new cream | Switch to a water-based or noncomedogenic one |
| Hair products on the face | Spots along the hairline and sides of the face | Keep hair and styling product off your skin |
| Hormones & Genetics | ||
| Flares with your cycle | Worse in the days before a period | Note flare days for a few cycles to show your doctor |
| Family history | A parent or sibling had acne too | Start treatment early |
What cheek acne means
Cheek acne is acne that shows up mainly on the cheeks: blackheads, whiteheads and red spots between the nose, ears and jaw. It means you first check what touches that skin, what you put on it and what your hormones do. The cause of cheek acne is usually one of those three, or a mix.
- Cheek acne is common in adult women. In a study of 208 women aged 25 or older with acne, 87% had it on both cheeks and 81.7% around the mouth. When cheek breakouts follow your cycle, the picture is closer to hormonal acne.
- In that study, 72.6% flared before a period and 53.8% with stress; cosmetics worsened acne that kept coming back.
- Pressure and rubbing count. In a small study of people who wore medical face masks all workday, the cheeks and chin had more inflammatory lesions than the forehead area between the brows.
- Greasy makeup and hair products, and touching or rubbing the skin, are known acne triggers.
How to Treat Cheek Acne
Treatment for cheek acne is the same as for acne elsewhere on the face, plus removing the trigger. It means a product alone works slowly if something keeps pressing on the same spot.
- Over-the-Counter Actives
- Salicylic acid at 0.5 to 2% and benzoyl peroxide at 2.5 to 10% are approved for acne without a prescription in the US. Among retinoids, adapalene 0.1% gel is sold over the counter too. They can cause redness and peeling, so apply them sparingly; benzoyl peroxide can bleach towels. For a single spot, the basics of how to get rid of pimples apply.
- Spot Treatments & Patches
- A spot treatment is a dab of the same actives on one pimple. A hydrocolloid patch covers a spot and keeps fingers off it.
- Dermatologist Care
- See a doctor if drugstore products haven't helped after several months, or you get cysts or scars. Ask your doctor about prescription retinoids such as tretinoin, antibiotics, and for women, spironolactone or birth control pills.
Prevention Tips
Preventing cheek acne means cutting down what rubs and coats the skin; daily habits matter more than any one product.
Change Pillowcases Weekly
Your cheek rests on the same fabric for hours each night, so a fresh pillowcase each week keeps that contact cleaner.
Clean Daily Items
Wipe your phone screen, wash makeup brushes and use a clean mask. Wash your face once or twice a day without scrubbing, and pick products labeled water-based or noncomedogenic (tested not to clog pores in most people).
What else it could be
- Itchy, same-size bumps near the hairline and cheeks that ignore acne products may be fungal acne.
- Redness without blackheads may be another condition; ask a doctor.
Your questions, answered plainly
What does acne on the cheeks mean?
Mostly that something touches, rubs or coats that skin: phone, pillowcase, hands, a mask or a heavy cream. In adult women hormones often join in.
What could be causing acne on the right side of my face?
Look at what touches that side. Most people hold their phone on one side and sleep on one side, and both press on the cheek every day. Try earbuds and a fresh pillowcase for a few weeks and see if that side calms down.
What do stress pimples look like?
Like any other pimple. Stress can make acne flare, though: in a study of 208 adult women with acne, more than half said stress made it worse.
Can hormones cause acne on the forehead?
Yes, hormonal changes can set off acne anywhere on the face. On the forehead, also check hair products, hats and headbands.
What is adult acne and what are its causes?
It is acne that keeps going, or starts, after your teens. In women it ties to genes, hormones, stress, diet, smoking and cosmetics together, and it is often mild but slow to clear.
