Unsure how to choose a smartphone without drowning in spec sheets? Focus on a smooth 120Hz display, all-day battery, enough memory and long software support. Skip the megapixel hype, and the rest falls into place.
You can find more buying guides in the mobile phones and gadgets section.
| Spec | Suggested floor |
|---|---|
| RAM and storage | At least 8GB RAM and 128GB storage |
| Display | 120Hz adaptive display minimum |
| Fast charging | At least 60% in 30 minutes |
| Software updates | At least five years |
| Dust and water protection | At least IP65 |
These figures come from SlashGear’s October 2026 guide and Unbox.ph’s January 2026 checklist. They can change as phones and prices move, so check the sources before you rely on them.
Start with your budget and how long you will keep the phone
Before you compare chips and cameras, decide how long you will keep the phone. Asurion’s buying guide puts it simply: a phone you plan to use for five years should have stronger specs than one you will replace in two.
Price comes next. The same guide says budget-conscious buyers can save hundreds of dollars with a mid-range phone, and most mid-range models still include features like multi-lens cameras and wireless charging.
If money is very tight, Digital Trends notes in a guide updated April 24, 2023 that you can still buy a smartphone for $100 or less. Treat that price as dated and check what is on sale today.
Then write down what you actually need. The same Digital Trends guide suggests asking yourself questions like these:
- Do you need a large screen, or one you can use one-handed?
- Do you want long battery life or the best camera you can get?
- Do you store a lot of music and photos on the phone?
- Do you travel enough to want a dual-SIM phone?
Which specs matter most?
Four specs shape your daily experience: the display, the battery, the memory and the camera. SlashGear’s October 2026 guide treats all four as non-negotiable, so use its limits as a starting point rather than a hard rule.
Display
SlashGear says a phone with less than a 120Hz adaptive display doesn’t cut it. It also notes that moving to 144Hz or 165Hz is far less impressive than the jump from 60Hz to 120Hz.
Asurion’s gaming advice lands in a similar place, recommending a high-refresh-rate display of 90Hz or 120Hz. The panel type matters as well, so the oled vs lcd comparison is worth a read before you decide.
Battery and charging
Capacity on its own can mislead you. SlashGear points out that a 5,000 mAh battery may look better than a 4,000 mAh one on paper, but the processor, display, software and your habits all change real battery life.
Unbox.ph still recommends at least a 6000mAh battery for getting through a heavy-use day, so read real-world reviews alongside the spec sheet. For charging speed, SlashGear’s floor is at least 60% in a 30-minute session.
Unbox.ph also lists wireless charging among the useful extras. If that appeals to you, the explainer on how does wireless charging work covers the basics.
Memory and storage
RAM is what helps your phone multitask, and storage is where your files live. Asurion suggests the following RAM levels:
- Calling, texting and web searches: 6 or 8GB of RAM.
- Running lots of apps at once: at least 8GB.
- Heavy gaming or editing photos and videos: at least 12GB.
For storage, SlashGear says a modern flagship feel needs at least 8GB of RAM and 128GB of storage. It calls 256GB a much more comfortable target if you will keep the phone for a few years.
You can move files to the cloud, but SlashGear warns you will likely pay a subscription and it is less convenient than keeping them on the phone.
Camera
Look past the megapixel number and think about the lenses you will really use. SlashGear says an ultrawide lens suits landscapes and group shots, while a telephoto lens helps with distant subjects.
Unbox.ph highly recommends OIS (optical image stabilisation) on the main camera for steadier video and clearer low-light photos. Asurion adds that if photography matters to you, you should read reviews and look at sample photos online before committing.
How to choose a smartphone: specs you can safely skip
Some headline numbers sell phones without improving your day. SlashGear says you probably don’t need five lenses, a 200MP sensor or 100x digital zoom.
- Huge megapixel counts, which say little about photo quality.
- Panels rated 144Hz or 165Hz, which SlashGear calls a far smaller leap than going from 60Hz to 120Hz.
- Battery capacity read in isolation, without checking reviews.
Popular Science, in a guide published Sep 18, 2019, argued that unless you shop at the very low-budget end or the ultra-premium high end, specs don’t matter too much. That is older advice, but it still helps when you are choosing between two similar mid-range models.
Asurion adds that budget phones may slow down during gaming sessions. For streaming music, sending emails and browsing social media, it says a budget phone should be just fine.
Updates and durability keep a phone useful
A fast phone with no security patches ages badly. SlashGear says updates should be guaranteed for at least five years, while Unbox.ph recommends at least 3 years for midrange phones and at least 4 years for flagships.
Those targets differ, so treat software support as something to check on the maker’s own policy page before you pay. The longer you plan to keep the phone, the more it matters.
For durability, Unbox.ph recommends at least an IP65 rating for protection against water and dust. Popular Science also noted in 2019 that some Android phones accept a memory card to expand storage, but iPhones don’t, so check the model you are considering.
Android or iPhone: sticking with what you know
Digital Trends says there are only two smartphone operating systems worth considering: Android and iOS. Popular Science adds that Android remains the more customizable of the two, while Apple’s iOS is more polished but more restrictive.
For most people, the real question is whether switching is worth the effort. Popular Science says that if you are heavily invested in Google’s apps, switching either way is pretty straightforward.
Its practical tip is to borrow a friend’s phone for 10 minutes and see how the other side feels. That costs nothing and can save you from an expensive mistake.
A short checklist before you buy
- Decide your budget and how many years you plan to keep the phone.
- Pick Android or iPhone, ideally by trying a friend’s phone first.
- Check the display, battery, memory and storage against the floors above.
- Read reviews and look at sample photos to judge the camera.
- Confirm the update promise and the dust and water rating.
Frequently asked questions
Is 128GB of storage enough?
Show answer
SlashGear treats 128GB as the minimum and 256GB as a more comfortable target if you keep a phone for a few years. Asurion notes that most new phones start at 128GB, and that cloud storage can offload files you don’t need often.
How much RAM do I need?
Show answer
Asurion says 6 or 8GB is fine for calls, texts and web searches, and at least 8GB suits heavy multitasking. Gamers and people who edit photos or videos should aim for at least 12GB.
Do I need to worry about 5G?
Show answer
Asurion says most new smartphones support 5G, including many budget and mid-range models. It suggests checking whether the phone supports the wireless bands your carrier offers, instead of asking only whether it has 5G.
Does a higher megapixel count mean a better camera?
Show answer
No. SlashGear says to look at the whole package, including sensors, software and stabilization, and warns that you probably don’t need a 200MP sensor.
