Although our smartphones are many things, one of their main functions is making calls. Many of us try to avoid ever having to talk on the phone, but there are situations when this is a must, eg. For example, if you wish your grandma a happy birthday or call 91
The call quality of phones depends on your mobile service provider. As with any audio, there are codecs or audio formats that are used to send the sound from your phone to anyone you call and vice versa, each with a different impact on call quality. For GSM users such as AT & T and T-Mobile, this means using adaptive codecs with multiple transmission rates. For Verizon and Sprint subscribers, use variable-rate codecs.
Your phone's involvement in this process begins with the support of these codecs. Features such as advanced voice services and HD Voice provide more bandwidth for calls and improve call quality. These must be supported by both the network operator and the phone for them to work.
However, the telephone is more than just a pure call quality. With the advent of robocalls and spam calls, having a phone that prevents you from receiving these calls is a long way off. It also adds, back up, and syncs contacts to make calls. After testing multiple phones, we tested the following four phones to get the best call experience.
Table of Contents
- Starting Price: RRP or From Manufacturer recommended retail price of the smartphone at startup. While this price does not always reflect the current price, it is the highest price the phone will sell.
- Support for US carriers: Which of the four major carriers is supported by the phone? While we could include US Cellular as of the first quarter of 2018, it will be used by only 5 million subscribers, which is 48 million fewer than the fourth-place Sprint. That's why we felt that only the top four vendors meet most of our readers' needs.
- Microphones: The number of microphones that you can use to transfer your voice during a phone conversation. With more microphones, you are less likely to have difficulty hearing the person you are talking to. That way, you can make your phone more comfortable without having to say "huh, repeat what you just said" several times.  Support for Wi-Fi Calls: On which of the four major US carriers does the phone support Wi-Fi calls? With Wi-Fi calls, you can make calls even when your signal is poor, as calls over the Internet are transmitted to your wireless router instead of mobile devices. It also offers clearer calls, as it uses a higher bandwidth than standard calls. While most phones support this feature, they do not support all network operators on all phones. However, every phone on our list supports the functionality of each supported mobile service provider.
- HD Voice Support: The phone supports HD voice calls on which of the four major US carriers. HD Voice Calling is a feature of VoLTE, in which the phone uses wideband audio to achieve better quality while talking on the phone. Similar to Wi-Fi calls, although most phones support this feature, the mobile service provider does not always offer this feature for non-mobile phones.
- Improved Voice Services: On which of the four major US carriers The phone supports advanced voice services. Enhanced Voice Services (or EVS) is a newer audio codec that enhances call quality even further. Currently, only Verizon and T-Mobile have activated it in their networks.
- Dual SIM: Whether the device offers dual-SIM support and how it is designed. With the dual SIM card, you can use multiple network operators on the same phone, so you have both a business and a personal line. With Dual SIM, you can also test multiple carriers for the best network coverage by comparing two carriers without having to remove the SIM card.
- Audio Ports: Which ports are available for wired earphones or headphones to make and receive calls. Only the Samsung Galaxy S10 + has a headphone jack that allows you to either connect a pair of earphones or use the data port.
- Hearing Aid Compatibility: Whether the phone is compatible with hearing aids. The rating "M" stands for hearing aids that receive audio with a microphone and send it to your ears. The rating "T" indicates the performance of hearing aids that are set to telecoil. The telecoil reduces background noise and feedback to improve audio quality. The higher the number, the better it is if every smartphone with hearing aid compatibility has at least 3. Any telephone with 4 exceeds the recommended standards.
- Call Recording: The ability to record the line audio of the phone during a call. You could record line audio in previous versions of Android, but Android 9 Pie did not support this feature. While each phone can record calls with a sound recorder app and play the call through handsfree, it does not have direct access to the audio of the call. However, this may change in the future for Android.
- Allows calls on other devices: The ability to make cellular phone calls from another device, such as an iPad or MacBook. This feature is only supported by iOS.
- Call Audio Routing: The ability to automatically send calls to Bluetooth headsets or speakers.
- Automatically answer calls: Ability to answer calls automatically without this being necessary Swipe first.
- 911 Shortcut Keys: Specifies whether you can quickly call 911 with the phone without having to pull up the selector button. By default, most smartphones end calls when you press the power button. Unfortunately, because the proximity sensor turns off the screen when you place your face on the screen of the phone to answer a call, sometimes it is forgotten and the screen wakes up with the button. You do not have to worry about this option.
- Mono Audio: The option to turn off audio in an earphone. If you answer a call during a task, you can continue working with two earbuds while answering the call. However, there are times when we need an ear to pay attention to our surroundings while staying on the phone. With mono audio, you can turn off an earbud and hear only audio from the earbud in your ear. The other ear stays free.
- Real-time text: Real-time text is text that is sent and received in real time, with no delays. Instead of waiting for the person to send the message, it will be displayed on your screen as you type. This is important for the deaf as it is a substitute for voice calls. In addition, it helps with 911 calls because the 911 operator can see anything you say while typing and eliminates delays in getting the help you need.
- Supports external TTY hardware: TTY or Text Phone is a type of device that allows the hearing impaired or speech impaired to communicate with others. Instead of speaking and listening, you can use these devices to type forward and backward messages.
- Backing Up Contacts: You can secure your contacts with the various methods of the phone. Only Samsung natively contains a second cloud storage, which can also be used.
- Sync contacts: Whether you can sync your contacts. This allows you to add or remove entries in the contact list of a device for all connected devices when using multiple phones.
- Add new contacts: The different methods for adding new contacts. Only Google Pixel 3 XL and OnePlus 7 Pro offer native Google Lens support, which allows you to add contacts by scanning business cards.
- Call Verification: A feature available only on Google Pixel devices. Users can use an AI to monitor calls. This device answers the call and asks the person on the line for information that you can read or listen to. If you want to answer the call, you can join the call or end the call at any time. This is a great tool against robocalls and spam calls.
- Call Control: A feature that allows you to manage calls through a hovering speech bubble. Use this balloon to turn the speakerphone on and off, end the call, mute calls and mute, and return to the call screen. This balloon is an overlay that allows you to interact with the phone on any screen.
- Spam Filter: The phone's native phone app warns you when a call comes in potentially spam by marking the incoming call. From there, you can decide if you want to answer the call or forward it to voicemail.
- Block Spam Calls: The phone's native phone app automatically blocks spam calls. Only Google's native phone app includes this feature. If you receive a call from a known spam caller, your phone will not ring. Instead, only one missed call is displayed in your history without notification. While iPhones do not have this feature, third-party apps can be integrated into the dialer to make this possible.
- Report spam: The ability to report a number as spam so it can be added to an automatic block list.
- Call Barring: The ability to block individual numbers from calling your phone in the native phone app. While iPhones do not offer the feature by default, third-party apps can be integrated into the dialer to allow this.
- Whitelist Numbers: The ability to block all calls except a specific list of numbers. With the Google Pixel 3 XL you can block all calls except those in your contacts.
- Video Chat Option: In the phone app, you can initiate a video chat. For iPhones, this means calls to iPhone or Mac users will be routed to FaceTime. For Android, this means that Google Duo calls can be made within the app.
- Local enterprise search: The ability to search for local calls companies within the native phone app. Using your location, you can use the dialer's Contacts tab to search for phone numbers for companies in your area, such as: B. restaurants and shops.
- Dark Mode: Indicates whether the native dialer has a dark mode. Only Google Pixel 3 XL includes the feature in the app, while Samsung and OnePlus have a system-wide dark mode that activates the dark theme of the dialer.
- Speaker Volume: How loud the speaker is when listening becomes a voice call. We used GSMArenas test for our numbers. It was measured with a digital sound / volume meter, a human male voice over the phone speaker.
- Battery Life: With the PhoneArena test, we recorded the battery life of each phone. For the PhoneArena tests, they used a custom web script to replicate a typical real use. The test was conducted at 200 nits and gives a good indication of how long the battery will last after unpacking. We were only able to use a battery test for calls because your phone collects data during a call. However, we felt that a test that mimicked general usage was more accurate than expected.
- 3G Talk Time Battery Life: We have specified the battery life of the phone when it is used exclusively for a phone call. The phone's screen was turned off and all other apps closed to limit their interference.
How We Picked These Phones
In order to narrow the field of phones from thousands to the four best for calls, we had to lay down some principles. Our first requirement was that the phone was officially released in the US within the last year. Most of our readers are in the US and if we recommend a phone, we want it to be future proof. However, this excluded some great phones from Huawei and Xiaomi.
We focused on the newest and best option for every phone on our list – for example, if the phone had a sibling device, we opted for the newer model. That's why we recommended the Galaxy S10 + over the Galaxy Note 9. In addition, all phones except the OnePlus 7 Pro come with a smaller version that offers the same performance, but with a smaller screen and a smaller battery. We chose the larger models for talk time reasons. However, if you want to save some money, you should look at the non-XL, Max or + versions of these phones years. With smartphones, we can manage these options in the phone app to avoid unnecessary calls to our mobile service providers or to visit their website. However, not all phones have this feature, so all of the phones on our list needed support for managing both features.
Over 5% of the world's population suffer from some form of hearing loss, many of which require a hearing aid to function in the world. With smartphone users expected to reach 3.5 billion by the end of 2019, we required hearing aid compatibility. Without compatibility, it is difficult to use a phone as the actual phone. After Android finally added support for native hearing aids, we felt it was necessary for every phone in the community to be used by people to make calls.
Finally, we focused on emergencies. Phones are not just designed to talk to family members, friends and telemarketers – they often determine whether we survive dangerous situations. In such situations, we are not always able to open the phone app and dial 911. That's why it's so important to have a link to simplify this process. This feature was recently added to iOS and Android and has therefore removed all older phones from our list that did not run the latest version of their operating system.
Phone 1: Google Pixel 3 XL
Thanks to Google's latest initiative Machine Learning greatly improved AI's Pixel 3 XL. Google has set itself the goal of improving the primary functions of AI, one of which is to make phone calls. With its exclusive "Call Screen" feature, a true spam blocker, a whitelist and more, there is no better phone than the Google Pixel 3 XL.
- GSM / EDGE: Quad Band (850, 900, 1800, 1900 MHz)
- CDMA EVDO Rev A: BC0 / BC1 / BC10
- UMTS / HSPA + / HSDPA: Bands 1 / 2/4/5/8
- FDD-LTE: Bands 1/2/3/4/5/7/8/12/13/17/18/19/20/25 / 26/28 / 29/32/66/71
- TD-LTE: Bands 38/39/40/41/42/46
Google recently announced that Google Pixel 3 and 3 XL are adding US official T-Mobile and Sprint support to their coverage. While it has already worked with both providers (in fact, all four major vendors work flawlessly with the Pixel 3 XL), it's nice that the phone is now sold in all vendors except AT & T. This means that AMR and EVRC are supported, the two codecs used by GSM-based and CDMA-based operators. With support for both, you can be sure the call quality is clear and your message is well received.
Where the Pixel 3 XL separates itself is the phone app. There are so many features that you want to do it again if you do not usually make a phone call. An important feature is the blocking of spam. Unlike many phones on the market, the Pixel 3 XL blocks known spam callers and not just notifies you. If callers in Google's spam database dial your number, they will not be notified in any way. Instead, you only see that they have called in your call log and through a notification point on the phone app's icon
. There's also spam filtering that lets Pixel 3 know if the call is coming in. May be spam. The incoming call is "spam-likely" so you can decide whether to withdraw or not. These and all calls can also be reported as potential spam to Google, which increases the attention of the app and eventually leads to it being automatically blocked.
Then there's the call screen. For the few calls that can bypass Google's amazing spam blocking, or even numbers that you're not sure about, you can check the call. Your Google Assistant will pick up the phone for you and ask the person about the purpose of their call. By default, you can use a live log that is displayed on the screen. However, if you press the volume rocker, the speaker will be turned on and you will be able to listen. If you want to talk to the person, you can enter the conversation at any time by pressing a button. If you hang up, you can do that as well. In any case, you no longer have to guess if this is a person you know.
Then there is the ability of Pixel 3 to block numbers. In addition to the usual blacklist, in which you add certain numbers, it is also possible to work with a whitelist. With a whitelist only selected calls are allowed through, all other calls are blocked. The three available options block all unknown calls, all private calls, or all numbers that are not in your contacts. You can also select all three for maximum protection.
Pixel 3 gives you all the features you need to make calls and avoid unwanted calls. It supports hearing impaired people via hearing aids, real-time text (RTT) and text phone (TTY). Thanks to Google Lens' ability to scan business cards, adding new contacts is easier. With Google Pixel 3 XL, you want to call because unlike in the past, this is not a frustrating experience.
Phone 2: Apple iPhone X S Max
With the Apple iPhone X S Max you not only get access to dual SIM For the first time, there are also some features that are only available for the iOS platform. With comprehensive support for both network operators and their features, you can be sure that iPhone users will have access to it when network operators offer a feature. And although the price is slightly high compared to other phones on our list, there are cheaper options in the Apple iPhone X S and X R . which offer the same features but with a small screen.
