What's the best way to charge a new cell phone battery to make it last the longest?

I’ve owned 3 cell phones so far and all of them had bad battery life. They would usually last a day or a day and a half after each charge. For my last 2 phones, I followed Cingular’s advice and charged the battery for 24 hours before using the phone. But that just made it worse. I have a Sony w600 phone and the battery is supposed to last 4-5 days.
What’s the best way to charge a new cell phone battery? Should I use the new battery right away or charge it before using it first. Thanks very much, John

I charged mine all the way first before the first use and it worked great.

The first time u charge you should let the battery drain, otherwise u will always experience a short battery life.

These days most batteries are charged in the factory, so when you get them just charge them for a couple of hours.

Also, with modern batteries (Lithium Iron) try not to let the battery drain all the way out like you used to with the old Ni Cad batts of old. The battery has no memory and last longer when you just charge it when you remember, if its half way done and you are at home for 30 mins, plug it in.

After a year I still get 2 full days use out of mine and that’s what I’m looking for. Your usage may warrant more, but if you can’t get to a power source in 48 hours, I’m guessing you have other issues to worry about

Like the owners manual says…you should always FULLY CHARGE the battery before initial use, at minimum overnight, preferably longer.
Newer batteries are less prone to memory than older ones, but it is also good to let the battery get down a good bit before recharging it. If you recharge an only slightly discharged battery on a regular basis, you will shorten the time it holds a charge and it’s life.

I have heard that should only charge it when it is dead, is this true? What else can I do to ensure my cell phone battery LASTS?

At night turn your phone off and hook it up to your charger. Of course, turn it back on in the morning.

Turn on the energy save option, turn off when you can.

You can charge the battery when it isn’t ‘dead’ but you should let it run all the way down periodically and charge it.

I have yet to have to buy a new battery before a new phone : )

You have to charge the thing practically every night, if you want to do any real talking on it during the day. A full charge does not last very long , if you keep yakking on the phone.

The old charging when the battery is dead thing was for old Nickel Cadium batteries… the new Nickel Medal-hydryde (sp) batteries do not have battery memory… so you can charge it any time.

To make your battery last, dont expose it to high temperatures (like leaving it in your car), FULLY charge it each time you charge it, and dont use your phone as much… ;p

Keep your calls short and sweet..Don’t talk while driving and only make calls that are useful , not wasteful…
