Get a charge out of these phones

Generally speaking, with moderate use, smartphones can give you a full day's performance before needing to be recharged, but not all gadgets are created equal — some simply run out of steam early, whereas others will hang in there for the long haul. Here are four smartphones with battery life that really impressed us.

CNET rating: 4.5 stars out of 5 (Outstanding)

The good: The Motorola Droid Maxx delivers astonishingly long battery life, a big, colorful screen, and a durable, attractive design. The phone performs inventive tricks such as responding to voice commands, giving screen-based notifications and quick-launching the camera, which takes pleasing pictures.

The bad: The Motorola Droid Maxx is expensive.

The cost: $299.99 to $699.99

The bottom line: If you can get past its steep price, the massive-screened Motorola Droid Maxx is currently Verizon's best Android smartphone.

CNET rating: 4.5 stars out of 5 (Outstanding)

The good: The Samsung Galaxy S4 has Android 4.2.2, a fantastic camera, a powerful quad-core processor, and software solutions for just about every scenario — including working as a TV/DVR remote. It's also comfortable in hand and has NFC, a user-replaceable battery and a microSD storage slot.

The bad: Its screen is dimmer than competitors', its plastic design gives it a cheaper look than its rivals, and we found the Galaxy S4's power button turned on at undesirable times. Not all camera modes work as promised, and a long list of software features can quickly overwhelm and confuse.

The cost: $99.99 to $494.99

The bottom line: Its laundry list of features require time and effort to truly master, but the Galaxy S4 is the top choice for anyone looking for a big-screen, do-everything smartphone.

CNET rating: 4 stars out of 5 (Excellent)

The good: The Samsung Galaxy Note 3 has a gorgeous and massive screen, a screaming quad-core processor and refined S Pen capabilities. It also has long battery life, makes clear calls and takes great pictures.

The bad: The Note 3 is expensive and large, and its faux-leather styling is crafted from cheap plastic.

The cost: $299.99 to $703.99.

The bottom line: While its plastic skin doesn't do its high price justice, Samsung's Galaxy Note 3 makes the most compelling argument yet for a supersize phone.

CNET rating: 4 stars out of 5 (Excellent)

The good: The Motorola Moto X squeezes a speedy camera and futuristic voice command capabilities into a well-crafted design that hits the sweet spot between screen size and comfort. The phone has great battery life and is available in an endless variety of customized designs.

The bad: With no expandable storage, space could get tight, especially on the 16GB base model. The screen isn't as big and sharp as those on some competing handsets.

The cost: $199.95 to $699.99

The bottom line: While it lags behind rival superphones in screen quality and storage capacity, the Moto X's superbly compact and comfortable design, whiz-bang voice controls and long battery life make it a worthy Android contender.
