If your Wi-Fi signal is this strong, you’re likely very close to the access point. -30 dBm – This is the strongest Wi-Fi signal.You’re unlikely to face any buffering and lags, and your download and upload speeds should be quite fast. -50 dBm – This is a stronger signal, and you’ll have faster internet speeds.You can perform all activities that require an internet connection. -70 dBm – This signal strength only supports very low-connection internet activities such as opening emails.You might be able to connect to the network, but you won’t be able to access any internet services. -80 dBm – This signal strength is highly unreliable.With this value, you won’t even be able to connect to the Wi-Fi network. -90 dBm – This is the weakest Wi-Fi signal strength.Keeping the screen brightness down will help, too.

Look out for features like optical (rather than digital) zooms, night mode for better low-light images, and optical image stabilization. Buy a case and screen protector: You'll protect your phone from costly damage, and will increase the phone's resale or trade-in value for when you're ready to move on.Otherwise, it's simple enough to switch platforms. Likewise, if you've invested in loads of Android apps, you'll want to stay on that side of the fence. Check if you're already invested: Have you already bought a lot of iPhone apps and iTunes movies? Stick with an iPhone if you still want access to them.Hold the phone at a store first: You may love or hate the way it looks and feels in person.Wait for this year's launch to get last year's phone for less, when stores and carriers may be trying to offload their existing stock.
