Which phone carrier is the best?

There is no single “best” phone carrier, as it depends on your location, but

Verizon, AT&T, and T-Mobile are the main contenders, each with different strengths. Verizon generally offers the most reliable and widespread coverage, especially in rural areas, while T-Mobile has the most extensive 5G network. AT&T is a strong all-around choice with a reliable 4G network and a solid 5G network that is still expanding. To find the best option for you, check coverage maps for your specific address, and consider providers like Google Fi or Mint Mobile, which run on these larger networks but can be more budget-friendly. 

Top carriers and their strengths
  • Verizon: Often considered the best for nationwide coverage, particularly in rural areas, with a very reliable 4G LTE network.
  • T-Mobile: Considered the 5G leader, with the most extensive 5G network coverage across the country. It is also frequently ranked high for customer satisfaction and offers competitive pricing.
  • AT&T: A solid all-around choice with a very strong 4G LTE network and an expanding 5G network that reaches a significant portion of the population. It is also noted for having a reliable network on college campuses and other specific locations. 
Other options to consider
  • MVNOs (Mobile Virtual Network Operators):These are smaller carriers that operate on one of the major networks, so they offer the same coverage but often at a lower price. Examples include:
    • Mint Mobile: Uses the T-Mobile network and can be very budget-friendly.
    • Visible: Runs on the Verizon network and is known for its low-cost, unlimited data plans.
    • US Mobile: Offers customizable plans on either the T-Mobile or Verizon networks.
    • Google Fi: Also uses the T-Mobile network but is praised for simplicity and reliability.
    • Cricket Wireless: AT&T’s prepaid brand, which is affordable and ranks well for customer happiness. 
How to choose the best carrier for you
  1. Check local coverage: The “best” carrier depends on your specific location. Use the coverage maps provided by each carrier (and third-party sites) to check signal strength at your home, work, and other places you frequent.
  2. Compare plans and prices: Look beyond the basic plan to compare features like unlimited data, hotspot access, and perks (such as streaming service subscriptions).
  3. Consider your needs: If you prioritize 5G speed and live in an area with good T-Mobile 5G, that might be the best choice. If you travel to many rural areas, Verizon’s broader coverage could be more beneficial. If you are on a tight budget, an MVNO running on a major network may be your best bet. 

Should I buy a refurbished cell phone?

Yes, you should consider buying a used cell phone to save money

, but be sure to buy from a reputable source to avoid scams and ensure a quality device. Buying a pre-owned phone is a good way to get a premium device for a lower price, but it’s essential to check the phone’s condition and make sure it’s unlocked and fully functional before purchasing. 

Pros of buying a used phone
  • Cost savings: You can save a significant amount of money, potentially up to 50% off the price of a new phone.
  • Access to better devices: Affordability allows you to purchase a model with features like larger storage or a better camera that might be out of your budget for a new phone.
  • Environmental benefit: Buying a used or refurbished phone reduces electronic waste.
  • For refurbished phones: These are often inspected, repaired, and given a fresh battery by certified technicians, making them a more reliable option than a typical used phone. 
Cons of buying a used phone
  • Risk of scams: Purchasing from an unreliable seller can lead to buying a stolen, broken, or locked device.
  • Potential for wear and tear: Used phones may have minor cosmetic imperfections, and the battery life might be degraded.
  • Risk of outdated software: Older phones may no longer receive software updates, which can pose security risks. 
Tips for buying a used phone
  • Choose a reputable seller: Buy from trustworthy vendors like major retailers, established refurbished phone companies, or directly from brands like Apple or Samsung.
  • Check the phone’s condition: Inspect the phone for any cosmetic damage and thoroughly test all features, including the battery, camera, and ports.
  • Verify the phone is unlocked: Make sure the device is not locked to a specific carrier.
  • Look for refurbished options: A certified refurbished phone often comes with a warranty and is a safer choice than a typical used phone, as it has been inspected and restored to full working order.
  • Stick to recent models: For a good balance of features and longevity, aim for a phone that is no more than two or three generations old. 

Is it bad to leave your phone on the charger overnight?

It is not bad to leave your phone plugged in overnight, as modern smartphones have built-in “smart charging” technology to prevent overcharging and damage. However, doing so can cause the phone to stay at 100% charge, which can lead to increased heat and slow battery degradation over time. For optimal battery health, it is better to unplug the phone once it reaches 100%
or use optimized charging features that limit the charge to around 80%.

Why overnight charging is generally okay
  • Smart charging prevents overcharging:
    Your phone’s battery will not be harmed by “overcharging” because its charging circuit will stop the flow of power once the battery is full.
  • It only provides “maintenance” charges:
    Once fully charged, the phone will only perform small “maintenance charges” to keep the
    battery at 100%.
Risks and things to consider
  • Heat can degrade battery life:
    Keeping a lithium-ion battery at 100% for long periods, combined with the heat generated during charging, can lead to a slightly faster decline in battery health over the long term. 

  • The risk of overheating:
    While rare with modern phones and quality chargers, a faulty or poor-quality charger, or placing the phone on an insulating surface like a pillow, can lead to overheating and fire hazards. 

Tips for better battery health
  • Use smart features:
    Enable “Optimized Battery Charging” on your phone to have it charge to

    100% just before you wake up. 

  • Avoid extreme heat:
    Don’t charge your phone in a hot car or on soft surfaces like a bed or pillow. 

  • Unplug once fully charged:
    For minimal impact, unplug your phone after it reaches 100%.

  • Use quality accessories:
    Always use a high-quality, certified charger and cable to avoid risks associated with faulty equipment.

Will Tesla’s new phone really put Apple’s iPhone out of business?

Rumors of a a “Tesla Pi Phone” have circulated online, and other companies have released phones under the Tesla brand name. The rumored “Tesla Pi Phone” features include Starlink connectivity, solar charging, and a focus on repairs and longevity, but these are speculative claims. Phones with the “Tesla” name, but not from the EV company, are basic feature phones with features like T-Flash memory card support, a camera, and a long-lasting battery, as seen on sites like Tesla.info and Amazon. 

Rumored “Tesla Pi Phone”
  • The “Tesla Pi Phone” is based on a viral rumor about a potential future product, and there has been no official announcement from Tesla or Elon Musk. 
  • Speculated features for the rumored phone include Starlink satellite connectivity, solar charging, and enhanced durability. 
  • It has also been reported that the phone would have a focus on repairability, with easy-to-replace parts and public repair manuals, notes this YouTube video. 
Other “Tesla” branded phones
  • Phones with “Tesla” in their name are available from other companies. 
  • These are typically basic mobile or feature phones, not high-end smartphones from the electric vehicle manufacturer. 
  • Examples of these phones include the “Tesla Feature 3.1” and the “Tesla EXPLR 9,” which can be found on retail sites. 

Cell phone batteries explained

Cell phone batteries are lithium-ion (Li-ion) rechargeable batteries that power devices by storing and releasing electrical energy. They consist of an anode, a cathode, a separator, and an electrolyte, which allows lithium ions to travel between the electrodes to generate an electrical current. When charging, ions move to the anode; when discharging, they move to the cathode, powering the phone. 

Components of a Li-ion battery:
  • The negative electrode, typically made of graphite, where lithium atoms store electrons during charging. 

  • The positive electrode, often made of a lithium cobalt oxide or similar compound. 

  • A physical barrier that prevents the anode and cathode from touching, which could cause a short circuit. 

  • A chemical solution that allows lithium ions to travel between the anode and cathode. 

How it works: 

  1. Charging:
    When the phone is plugged in, electrons enter the battery, causing lithium ions to move from the cathode, through the electrolyte, and deposit themselves into the graphite structure of the anode.
  2. Discharging:
    When the phone is in use, the process reverses. Lithium atoms at the anode lose electrons, which flow through the device’s circuit to power the phone. The lithium ions then travel through the electrolyte to reunite with the electrons at the cathode.

    Key characteristics:
    • High energy density: Li-ion batteries can store a lot of energy in a small, thin package, allowing for slim phone designs. 
    • No memory effect: Unlike older battery types, Li-ion batteries don’t need to be fully discharged to maintain their capacity. 
    • Rechargeable: They are designed to be charged and discharged many times. 
    Safety Considerations:
    • Li-ion batteries contain volatile, flammable chemicals, making them a potential fire hazard if damaged or misused. 
    • The U.S. Consumer Product Safety Commissionrecommends using only compatible batteries and chargers to avoid damage and unsafe conditions. 

Do screen protectors really work?

Screen  protectors work by providing a sacrificial barrier that absorbs impacts and prevents scratches on your device’s actual screen, though they don’t guarantee 100% protection. Tempered glass protectors are particularly effective at absorbing shock, breaking themselves to protect the phone’s display from cracks and costly repairs. In addition to impact resistance, they shield against everyday wear and tear, such as damage from keys or coins in a pocket, helping to maintain the device’s condition and potentially its resale value.  

How Screen Protectors Work
  • Scratch Protection:

    Protectors act as the first line of defense against items like keys, coins, and other abrasive surfaces, preventing them from scratching the screen’s glass. 

  • Impact Absorption:

    Tempered glass screen protectors are designed to absorb the force of a fall. When the device is dropped, the protector is intended to break or shatter instead of the phone’s screen, dispersing the impact and saving the display from damage. 

  • Preserving Structural Integrity:

    Scratches on a phone’s screen can weaken its structure, making it more susceptible to larger cracks. A screen protector prevents these initial scratches, which in turn reduces the likelihood of future cracks. 

Limitations of Screen Protectors
  • Not Indestructible:

    While effective, screen protectors are not invincible and can break upon impact. 

  • Varying Effectiveness:

    A protector’s effectiveness depends on factors like the height of the drop, the surface it lands on, and the type of material the protector is made from. 

  • Drop Protection is Limited:

    A screen protector offers some protection from drops, but it will not entirely prevent damage from all impacts. A good protective case, especially one with a raised lip, offers more comprehensive drop protection. 

In Summary
Screen protectors are a worthwhile investment for most users. They offer significant protection against the common scratches and scuffs that occur during daily use and provide a crucial layer of defense against cracks and impact damage from drops. By sacrificing themselves to protect the expensive and critical display, they help extend the life of the device and save money on repairs.
