What to know about the iPhone battery

Smartphone batteries have never quite been able to keep up with all-day use. Just when you're about to jump on an important business call, or you need to tell your spouse you're running late from work, you see your battery percentage in the red. It's frustrating to say the least and phone makers are aware.

Noam Kedem, vice president of marketing at Leyden Energy, said in a guest post on CNET that Li-ion battery constraints explain why smartphone vendors spend millions of dollars on new designs and other aspects of the phone to improve battery performance.

"The energy density of a Li-ion pouch cell determines how much runtime you can pack into a given size (volumetric) or weight (gravimetric)," Kadem said in the news source. "Unfortunately, battery manufacturers are having a harder and harder time increasing energy density. This is why non-replaceable Li-ion pouch batteries are popular with smartphone and tablet designers."

Kadem said he believes a next-generation battery could arrive within 12 to 18 months, and could provide a 20 percent lift in battery charge for the same sized battery.

Although fully functional batteries may be a cause for frustration, typically you can adjust settings on your iPhone to reduce power consumption and increase longevity. However, if the battery continues to have issues even after making adjustments, then there may be a problem with the battery itself. At that point, it may be wise to seek out iPhone repair services. Professional technicians can determine whether there's a problem with the battery and advise you on the best option to move forward.
