Some have noticed a curious dichotomy within the smartphone world, with customers placing two, often divergent, demands on manufacturers. One, users want a phone that has increased speed, capability, and versatility. Two, they want a longer battery life. According to research done by J.D. Power and Associates, battery performance is one of the top critical components customers look at when determining how satisfied they are with their current smartphones. This leaves little doubt that it ranks highly among the factors considered when buying a new one. To help curb dissatisfaction before a purchase, here are some of the phones blowing away the competition in the area of battery life.

LG Optimus L9

The LG Optimus L9 is aimed directly at the mid-range market, though most analysts agree that it offers tremendous value for the $79.99 MSRP. As part of T-Mobile’s line of contract phones, the Optimus lags behind powerhouse phones like the Galaxy series, though this is understandable given that it is sold for nearly three times less than those competitors. It is in the realm of battery life, however, that the Optimus really shines. According to some tests, the phone is able to provide over 7 hours of use with its 2150 mAh batteries, making it among the best values on the market.

Samsung Galaxy Rugby Pro

Answering consumer demand for smartphones that can stand up to intense athletics, hiking, and perhaps even an accident or two, Samsung delivered the Galaxy Rugby Pro. Priced at just under $100, the Rugby is fitted with a tough build and a processor that leaves little to be desired. It also offers lightning fast LTE speeds, explaining why many tech editors have named it their pick as the rugged phone of the year. Of course, if you’re out hiking in the wilderness, you need a phone with a long-lasting battery. The Rugby provides just that, with nearly 8 hours of battery life for heavy, Internet-intensive use.

Motorola Droid Razr MAXX HD

It has been difficult for Motorola to overcome its public reputation as a phone best left in the early 2000s. Once the reigning king of cell phones, Motorola has had to scratch its way back into competition. To the company’s credit, however, they have managed to do just that. Their most recent Razr model offers a stunning 4.7 inch high definition display along with 4G LTE data speeds that leave much of its competition in the dust. It wins another medal for its battery life, which clocks in at over 8 hours even with constant, draining usage.

Samsung Galaxy Note II

If there is a clear victor in the battle for battery life supremacy, it has to be the Galaxy Note II from Samsung. Not only does the phone offer one of the largest displays on the market (5.5 inches), it is equipped with one of the biggest batteries. At 3,100 mAH, this is a battery meant for serious use, and that’s exactly what Samsung delivers. With a lifespan lasting over 10 hours, this is the smartphone for those who are tired of recharging in the middle of the day.
