The battery life of mobile devices varies widely.

Laptop computer batteries can last as few as 3.5 hours unplugged or as many as 19 hours, and tablet battery life can range from five hours to 16 hours, according to Consumer Reports. Smartphone batteries start with as much as eight hours of charge, but some models can last as long as 24 hours.

To help you narrow down the options, the magazine has highlighted three laptops, tablets and smartphones with some of the longest-lasting batteries:


  • Toshiba Portege Z30-BSMBN22: 19 hours
  • Apple MacBook Air 13-inch MD760LL/B: 16.25 hours
  • Lenovo ThinkPadX1 Carbon: 13 hours


  • Sony Xperia Z3 Compact: 16 hours
  • LG G Pad 7.0: 15.9 hours
  • Amazon Fire HDX 8.9: more than 15 hours


  • Samsung Galaxy Note 4: 24 hours of talk time
  • LG G3: 24 hours of talk time
  • Apple iPhone 6 Plus: 17 hours of talk time

At least when it comes to smartphones, The Wall Street Journal argued earlier this year that smaller and lighter models aren’t necessarily better:

One of the things we’ve come to expect from phones and other gadgets — that every year, they become thinner and lighter — is a trend that has outlived its usefulness…

One of Apple’s larger phones, the iPhone 6 Plus, has significantly better battery life than its smaller cousin, principally because of its larger size. There’s simply more unused volume into which Apple was able to cram battery.

The iPhone 6 Plus has a 5.5-inch display and weights about 6.1 ounces. The iPhone 6 has a 4.7-inch display and weighs about 4.6 ounces.

The other two smartphones that Consumer Reports highlighted also are relatively big and heavy, with displays of at 5.7 inches and 5.5 inches, respectively, and weights of about 6.2 ounces and 5.4 ounces.
