How to choose the best smartphone for you: what to check before you buy

There is no single best smartphone. The best phone is the one that works on your mobile network, gets security updates for as long as you plan to keep it, and does the few things you use most, well. This guide lists what to look up for each phone you are considering, before you pay, so you can compare them in the same way.

Why the adverts and the shop are not enough

Phone adverts show the best result a phone can reach. The detailed specifications often say something different. For example:

The same phone name is often sold in several versions, with different storage, memory and network support. So check the exact version you would buy, using the maker's own specifications, and check the same things for every phone.

Before you look at any phone

Write down your answers to these four points. They decide which checks in the list matter most to you.

The checklist

The checks are in three groups. Must have means a problem here can make it hard to use or costly to fix. Nice to have means it makes a real difference for many people. Optional means it only matters to some people. When you open the checklist in NeutralPick, you can move any check to a different group to match your answers above.

The button opens this checklist in NeutralPick. There you can:

  1. Remove the checks that don't matter to you, add your own, and move checks between groups.
  2. Add each phone you are considering.
  3. For each phone, fill in what you found on the maker's website, its support pages and the shop's product page.
  4. See every phone side by side.

Claims to look at carefully

Adverts and product pages often describe the points below in vague terms. When you see one, look for the specific information shown here. If you cannot find it, assume the answer is "no" or "only partly".

What to do with what you found

  1. Put all the phones side by side.
  2. Look at the Must have checks first. If a phone gets a No on one of your must-haves, remove it, however good the rest looks. Look closely at any Partial.
  3. If two phones are close, read reviews from owners who have used them for several months, especially about battery life and updates.
  4. Before you buy, check the shop's return policy, and check with your mobile network that the exact version works on it.
