In one of the discussion, one purchaser complained, “I am earnestly reading all I can about this battery because I am very disappointed in it's "life". I now own a charger at home, in my car, and the sync in my office. If I do not keep it plugged in at all times it is dead at 5:00 PM each day. Either I have a defective battery, it's the worst I have ever owned, or I have done or am doing something wrong."



It is worth mentioning that the disgruntled customer bought the phone on the opening day of the release. “I leave it in a charge cradle every night, I have wi-fi off, no blue tooth etc. I do use the web from time to time and I do check email. I seldom send email unless I have a wi-fi close by. So other than talking on the phone I do not think I use the other features enough to kill the battery" said the buyer.

According to the Apple iPhone concern on its battery issue, it says “Most lithium-ion batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. That’s about two hours of charge time to power an iPod to 80% capacity, then another two hours to fully charge it, if you are not using the iPod while charging. You can charge all lithium-ion batteries a large but finite number of times, as defined by charge cycle."

It elaborates further, “A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge."

How to Maximize Power Use

The length of time your battery will power your device depends on how you use it. For instance, watching a DVD will use up your notebook battery’s power more quickly than simple word processing. You can follow some easy steps to maximize your notebook, iPod, or iPhone battery life.
