Answers to the most common questions about upgrading your Android phone — when to buy, how to choose, and how The Upgrade Radar works.
Most people get the best value from a 2–4 year upgrade cycle. Annual upgrades make sense only if you need a specific feature your current phone lacks, or you are getting a significant resale credit. The sweet spot for most users is upgrading when their current device becomes noticeably slow, stops receiving security updates, or when the price of a new model has dropped materially from its launch price.
It depends on where you are in the release cycle. If a new model has been officially announced, waiting is almost always the right call — you avoid buying hardware that will be superseded within weeks, and you gain access to clearance pricing on the current generation. If the next model is still 6+ months away, buying now makes sense as long as the price is right. The Cycle Advice on each device page tells you exactly where each series stands.
The two most reliable windows are Black Friday / Cyber Monday (late November) and Amazon Prime Day (July). Both consistently produce the deepest discounts — often 20–35% below standard retail. A third window worth watching is the weeks immediately after a new flagship launches: retailers discount the outgoing model aggressively to clear inventory.
Sometimes — but only with a significant discount. If the price drops enough (typically 25%+), the older model can represent excellent value, especially for mid-range series. For flagships, be more careful: you are sacrificing one full generation of performance improvements and one year of guaranteed software support. Weigh the savings against the gap in useful life.
Hardware typically remains capable for 3–5 years. The harder limit is software support: once a manufacturer stops providing security updates, your phone becomes increasingly vulnerable. Google Pixel and Samsung Galaxy flagship models now promise 7 years of OS and security updates, making them the longest-lasting Android options by this measure.
Flagship phones (Galaxy S, Pixel Pro, OnePlus Flagship, Xiaomi Flagship) use the fastest available processors, the best camera hardware, and premium materials. They typically cost $800–$1,200+. Mid-range phones (Galaxy A, Pixel, OnePlus Nord, POCO X) trade some camera and processing power for significantly lower prices — usually $300–$600 — and represent the best value for most users. Budget phones prioritize affordability over features, usually below $250.
Samsung Galaxy devices offer more hardware variety, broader carrier availability, and a rich feature set including DeX (desktop mode) and integration with Samsung's ecosystem of tablets, watches, and TVs. Google Pixel devices offer a cleaner, faster Android experience with guaranteed first access to new Android OS versions, exceptional computational photography, and typically longer software support guarantees. If camera accuracy and software purity matter most, Pixel is the better fit. If ecosystem breadth and feature richness matter, Samsung wins.
Foldables (Samsung Galaxy Z Fold/Flip, Google Pixel Fold) have matured significantly. The hinge crease is much less noticeable than in early generations, and durability has improved. The main trade-offs remain: they are expensive (typically $1,200–$1,900), and they are heavier and thicker than traditional slabs. If you genuinely use the larger screen for productivity — documents, multitasking, creative work — the form factor pays for itself. Casual users will find the premium hard to justify.
Very important, and often underweighted. A phone that receives 7 years of updates (Galaxy S, Pixel) at $800 may cost less over its life than one with 3 years of updates at $600 that you have to replace sooner. Security updates are non-negotiable — an unpatched device is a genuine risk for anyone who uses mobile banking, email, or cloud storage.
Flagship phones typically drop 10–15% within the first 3 months and 20–30% within 6–12 months. Mid-range devices drop faster — often 20–25% within 3–4 months. The sharpest drops happen when the next generation is announced: current-generation inventory is discounted heavily as new stock arrives. Our Offers Advice tracks when these windows are active.
Carrier and manufacturer trade-in promotions can be extremely aggressive — sometimes offering $400–$600 for an older flagship toward a new purchase. These deals are usually best in the first month of a new model's launch. Compare the trade-in offer to what you would get selling privately (eBay, Swappa, Facebook Marketplace), where you typically get 20–40% more cash — but with more effort and risk.
Certified pre-owned devices from manufacturer programs (Samsung Certified Re-Newed, Google Certified Refurbished) are generally low-risk and can save 20–30%. Third-party refurbished devices vary widely by condition — look for Grade A listings from established sellers with return policies. The main risk is battery health: always check or ask for the battery cycle count or health percentage before buying.
The Upgrade Radar is an independent site that tracks Android smartphone release cycles and seasonal pricing to help you decide the best time to buy — or wait. Every device series we cover shows two signals: Cycle Advice (how close is the next model?) and Offers Advice (are deals available now?). See the About page for the full story.
Cycle Advice is based on the historical gap between major model releases for each series and how far into the current cycle we are. Offers Advice is based on known seasonal sale windows and post-launch pricing patterns. For the full methodology with exact thresholds and data sources, see our Methodology page.
Our advice is based on publicly available historical data — release dates, confirmed announcements, and documented sale patterns. We do not receive payments from manufacturers, retailers, or carriers. We are not affiliated with any brand. Our only interest is giving you an accurate, timing-based signal. See our About page for more on our editorial independence.
We update immediately when a new model is officially announced or released, and at the start of major sale seasons. Each device page shows a "Last Updated" timestamp so you know how fresh the data is. You can also subscribe to notifications to be alerted when advice changes for a device you care about.
