Mobile Phone Charging

Is it wise to let a phone battery run down completely before charging it again, or can you charge, say, everyday?

I wouldn't normally ask this question but after what happened with my laptop battery I'm a bit weary (for those who don't know, I kept charging it up when it hadn't drained completely and it's now no good unless it's constantly on charge!)

Thanks :)

I only plug my charger in when the phone dies completely or gets on my wick, whinging, beeping 'low-battery-alarm'. You tend to know when it's going to need a charge when you get used to it and plan ahead, my battery lasts 3 days, on the third day it starts to whine and gets plugged in overnight.

It depends on what type of battery you have. If it is an NiMh it doesn't have a memory problem so can be charged as and when you like. Most others can only be charged completely from scratch, ie. it needs to be completely run down before a recharge.

"I kept charging it up when it hadn't drained completely".

But surely, whenever you plug a laptop into the mains and switch it on, the battery is then charged automatically.

Thus, it's rather difficult to completely discharge the battery isn't it?

I say..

Not that hard really. Use it, when it turns off, as the battery's flat, then plug it in to the mains?

They tell you when you get the new phone, to condition the battery. That is the battery will only reach optimum capacity when it has been completely depleted and recharged several times.

I tend to stick with this, only charging the battery when it's got that low the phone turns itself off.

First charge with a new mobile should be for at least 16hrs this is for as Pooke said to condition the battery.

Future charges should then be made when you recieve the low battery warning on your phone or the battery dies, then every now and again it is a good idea to completely discharge the battery and leave it on for an overnight charge, I have had my phone for over a year now and the battery still lasts for about 4days keeping to the above

Ok, so I think i was a tad too keen on the new phone. I left it on charge to begin with until it said "Charge Complete" (which ws a lot shorter than 16 hours). So, have I screwed the battery up already? Will it's 'memory' not last as long as it could?

Thanks

No, just run it completely flat and then give it a good overnight charge. Then only charge it when it runs out. I have had my mobile over 4 years and only charge it when the phone won't switch on. I use a car charger which is a lot quicker than the house mains and have not had any problems.

click here for battery info. Only one full discharge out of thirty charges is needed.

Quote from link.... Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory.
