CNET shows you our recently reviewed cell phones that deliver the best in talk time battery life.
Motorola Droid Razr Maxx (Verizon Wireless)
A phone may be able to do everything, but if it can't make a decent call or its battery life is poor, then it's worth not much. Unfortunately, as smartphones have become more powerful, batteries have struggled to keep up with the demand of large displays and powerful processors. Of course there are exceptions like Motorola's Droid Razr Maxx, but now we commonly measure battery life in hours instead of days. Of the latest handsets that CNET has reviewed, here are the 20 models with the longest battery life as measured by our talk time battery drain tests. For more results, see our full cell phone battery life charts.
CNET Review bottom line: The Motorola Droid Razr Maxx proves that a powerful Android superphone can remain thin yet still promise marathon-worthy battery life.
CNET Review bottom line: With the iPhone 4, Apple again shows that it is a powerful player in the smartphone wars. It won't be for everyone, the call quality and reception vary if you don't use a case, and AT&T's network remains a sticking point, but the handset's striking design, loaded feature set, and generally agreeable performance make it the best iPhone yet.
CNET Review bottom line: If looks aren't important, and you want a basic rugged phone that can make good calls and withstand being kicked around and dropped underwater, consider the DuraPlus. But be aware: its clunkiness will give your hand a workout.
CNET Review bottom line: The Samsung Captivate Glide is one of AT&T's most powerful QWERTY smartphones, and at $150, it won't cost you an arm and a leg. However, the ultraflat keyboard may be more hindrance than help to all but the most dedicated keyboard enthusiasts.
CNET Review bottom line: With venerable specs, including a terrific camera and large, beautiful screen, the Samsung Galaxy S II is holding true to its claim to fame as the everyman's high-end Android phone.
CNET Review bottom line: With its dual cameras, strong processor, and attention to camera detail, the Huawei Mercury tops Cricket's charts for a non-Muve Music smartphone, but insatiable Web surfers may still want to shop around.
CNET Review bottom line: The iPhone 4S isn't the king of cell phones, but it's part of the royal family nonetheless. Even without 4G and a giant screen, this phone's smart(ass) voice assistant, Siri, the benefits of iOS 5, and its spectacular camera make it a top choice for anyone ready to upgrade.
CNET Review bottom line: Up to military specifications, the durable Kyocera DuraCore runs on Sprint's fast Direct Connect push-to-talk network, but those who prefer a camera and a phone they can dunk in water will want the DuraMax.
CNET Review bottom line: If you're looking for your first 3G smartphone, the T-Mobile Prism will deliver basic calling, texting, and Web-browsing requirements all for $20. Just don't expect blazing speeds or great photos.
