How long should I charge my cell phone battery for?

[HiTek21]

I picked up a new Samsung S105 phone today and I put it on the charger for 3 hours and the phone says fully charged. The guy behind the counter told me to charge the phone for 13 - 15 hours for each new battery.

Yeah, let it charge for at least 12 hours. I think this has something to do with the "memory effect" of batteries in devices. Google it. But also, you should let your phone batter drain as much as possible, and don't be one of those people that charges it all the time. Eventually, your battery "forgets" what a full charge is, and will show up as charged, even if it isn't. I forgot, but I read up on this a while ago. I don't know if newer batteries are better at this.

I could be wrong about ALL of this, so google "memory effect batteries", and you should find some stuff.

new cell phones use li-ion batts, and discharging them completely is the way to kill them fast. Li-ion should NEVER be drained completely, and are safe to top off the charge on them as often as you like with no negative effects.

The Correct.

Most new phones will use Li-ion battery. Charge them up as much as you want. They are fine.

When you first get a phone charge it for 24hrs first. After that whenever you want.

Yep. My previous cell phone, before I replaced it, was on the original battery after 2.5 years and still going strong.

Just giving past experience info will cell phone batteries.

 

[jurzdevil]

why not charge it till its full?

 

[0roo0roo]

my nokia from amazon came with a sheet that said it was precharged

go figure.

li ion no mem effect.

 

[sciencewhiz]

even though li-ion batteries don't have a memory effect, they do loose capacity with use. Don't charge them more often then necessary, but don't fully discharge them either.

well said. If it shows a full charge after the initial extended charge, Don't keep it on the charger. That's another way to kill a battery off fast.

Charge only when necessary.

over night should be fine

Why not keep it on the charger? If your charger trickle charges then no problem.
