Don't think it matters much with Lithium Ion types does it? The NiCads of old were memory types, but not the former or Nickel Metal Hydride, if my info source is accurate?

Sorry to butt in chaps.

ZF is right regarding battery technology but the phone still needs to learn when it is empty and when it is full so it is good practise to let it run down every so often so the software can calibrate empty & full. Although it depends how posh your phone is...

Hello bobda

Thanks for that. The phone is a Nokia 5800 express music.
Not very posh I think

I actually think the calibration 'software' is in the battery on a lot of phones.

Calibration software is part of the phone's operating system, and isn't necessarily down to 0%-100% charges; it is constantly monitored and changed.
Li-ion batteries can actually be damaged by discharging, and it is actually bad practice to let them run out completely. On a mobile phone, their operating range is only from about 3.5v-4.2v.
Go below 3.0v and you have a permanently damaged battery on your hands. The software in your phone will prevent this happening.
Go above 5.0v and you could have an explosion on your hands. The chip in your charger will prevent this from happening.
That is also a very good reason to ensure you use compatible batteries and chargers for your device.

(Those figures are from memory, but have a read here and it will tell you the actual values.)

In theory, charge it when you think it needs charging, don't when you don't.

In practice though, as there is no need to let it run low, why not just do as I do and stick it on charge every night?
You won't use any more electricity doing so, as Li-ion batteries don't continue to charge once full, and you know you'll have a full battery every day.

Although they don't have a memory effect, Li-Ion batteries do have a limited charge cycle rating meaning they may only be good for 1000 cycles (discharged to charged). In reality, that is three years of daily recharging and as most mobile contracts are 18 or 24 months and the phone is replaced with the contract it shouldn't matter.

It's just like having a nice car but never driving it in fear of the tyres going bald - don't worry about it and charge it when it needs charging.

I've always done it and never had any problems. If I was ever without a charger, my old phones would still hold the same charge as they always did.
Can't say the same for my last few phones; with the constant internet syncing and massive screens, they would barely make it into the next day with me anyway!

My phone is not on contract and I might keep it for
a few years yet. I like to look after things which is
why I was asking for the best practice.

i just plug mine in every night so it's fully charged for whatever the next day may bring, i've always done this with various phones and never had an issue, sometimes the battery is down to 20-30% other days it's only 60-70% depending what i've been doing etc
