Four years instead of two: what actually decides it
The short answer
Heat is what ages a battery, a grippy case prevents more breakages than a thick one, a charging port needs emptying every few months, and a backup you have never verified is not a backup. Almost everything else people worry about matters less than those four.
Heat, which is most of it
A lithium cell ages fastest when it is hot, and the two things that make a phone hot are charging it fast and working it hard. Doing both at once, in a car in July, on a dashboard mount, is the single worst thing you can routinely do to a phone.
You do not need to baby it. Charge it when it needs charging, fast if you are in a hurry. What is worth changing is the combination: take the case off if it gets warm on charge, keep it out of direct sun, and do not game while it is plugged in.
The other heat source people miss is wireless charging under a pillow or in a bed. It is the least efficient way to charge and the wasted energy becomes heat right next to the cell.
The case matters more than the protector
Most of the screens that arrive here were not dropped from height. The phone slid off a car seat, a sofa arm or a bathroom shelf. A grippy case prevents that drop from happening, which is worth more than a thick one that survives it.
A raised lip around the screen means a phone landing face down rests on the case rather than the glass. A raised camera lip protects the part that stands proudest and is most expensive per square millimetre.
A tempered glass protector is the cheapest insurance in the shop and it handles scratches and small knocks. It will not save a screen from a hard corner drop, because that force travels through the frame.
Empty the charging port
A large share of the phones that arrive here not charging have nothing wrong with them. The port is packed with pocket lint, compressed a little further every time the cable goes in, until the plug can no longer reach the pins.
Every few months, with the phone off, clear it with a wooden toothpick. Not a pin, not a paperclip, not compressed air. The pins bend, and once they are bent the free clean becomes a paid replacement.
The same goes for the speaker grille, gently, with a soft dry brush. Compacted lint muffles a loudspeaker long before it silences it, and people live with a phone they think has a failing speaker for months.
Back it up, and check that you did
Turn on the automatic backup your phone already has, then check once that it is actually running and the last backup date is recent. That is the whole task and it takes two minutes.
The check is the part people skip, and it is the part that matters. A backup that silently stopped eight months ago because storage filled up is not a backup, and the day you find out is the worst possible day to find out.
The most upsetting conversation in this shop is not about a price. It is telling somebody their photos are on a board that will not power on.
The things that matter less than people think
And one that matters more than people think: what happens when it is not being used. A phone or laptop going in a drawer for months should be left near half charge rather than full or empty, because a cell stored at either extreme degrades faster.
- Charging overnight. Fine, and modern phones manage the last stretch themselves
- Charging to 100 per cent. Fine occasionally; it is sitting there hot that does damage
- Letting it drop to 20 per cent. Fine. Deep discharges to zero are the ones to avoid
- Closing apps to save battery. It does not, and on most systems it costs more to relaunch them
- Third-party chargers. A good one is fine; a cheap unbranded one is a genuine risk to the port and the cell
- Updates. Install them. The security fixes matter more than the occasional first-week battery dip
When the phone stops being the limit
Batteries are usually the first thing to go, at two to three years, and a replacement is the cheapest repair that makes an old phone feel new.
After that it is usually software support rather than hardware that decides when a phone is finished. A device that stops receiving security updates is one to plan around, whatever condition it is in.
Which is why the honest advice on a five-year-old phone with a tired battery and a cracked screen is sometimes that it is not worth both repairs. We will tell you when that is the case.
Common questions.
Not on its own. Modern phones stop drawing current when full and most learn your routine to finish the last stretch near morning. Heat is what does the damage, so overnight on a bedside table is fine and overnight on a wireless pad under a pillow is not.
No. That was true of a much older battery chemistry. Lithium cells prefer partial charges to deep discharges, and running to zero regularly is harder on them than topping up.
Longer than most people keep them. The battery usually goes first at two to three years and is a cheap fix. After that it is software support rather than hardware that usually decides.
For scratches and small knocks, yes, and they are the cheapest thing in the shop. They will not save a screen from a hard corner drop, because that damage travels through the frame rather than the front.
Yes, every few months, with the phone off and a wooden toothpick. Never a pin or compressed air. It is the single most common cause of a phone that has stopped charging.
