Too much charging?

I charge my phone alot. Whenever im home I usually plug it in or whenever im driving I plug it in. I was wandering if this burns out the battery or does anything negative to the life of it. Also, I never let it go all the way down and die before a recharge. But I think I read on here thats not necessary because its lithium. Any help would be appreciated, thanks!

Definitely not too much searching......

couldnt find too much to answer my questions searching on here. but nevermind my dad answered all my questions. this thread can be closed. haha

A tip that many people do not do.

To run your battery to your full extent, the first time you turn your phone on DO NOT CHARGE IT. Let it die, do not let it "almost die" let it die to the extent where u cannot turn in it.

Works great

Actually thats not necessary with lithium batteries. with older batteries (i forget the chemicals, my dad told me) you had to do that. you had to do this because these batteries had "memory." if you ran you phone down half way before the first time you charged it, the battery thought that it was empty since you are charging it. so from then on, whenever your battery hit its halfway point, it was dead, because the battery thought that it was since that was when you charged it. lithium batteries do not have memory and therefore you can charge them when you want and however often you want.

charging

The iPhone battery does not have a memory, thus it is not necessary to full discharge the battery. And charging "a lot" or at any time, starting with a full charge, half charge, whatever, doesn't hurt battery life at all. About the only thing that hurts battery life (damages the battery) is too much heat... like leaving your iPhone in a hot car or in the hot sun.

I figure that I might as well run the battery as ragged as I can within the first year, that way it's within Apple's one-year warranty and I can get a battery replacement for free. If not, it's still only $70 or so and by then I should have a new iPhone anyway (once again assuming the introduction of an iPhone 2).

They will replace the iPhone battery for free for the first full year? Maybe I should take advantage of this offer on the last day of my 1 year warranty.. There has to be a problem with the battery to get a replacement or can i simply ask for a new battery? Can I just "lie" to them and tell them the iPhone's battery was bad..?

Draining the battery is never necessary.

The iPhone can withstand approximately 400 charges before it looses about 20% of it's full charge time. From there, the time will continue to decrease. Once it gets too low for your liking, you can send it in to Apple for the battery to be replaced.

If you intend on getting the second iPhone, I say you have no reason to worry. If you think about, 400 charge cycles is a lot. The second iPhone will be out in '08, and your battery should still be a-okay then.

i once heard that if you plug your iphone in over night then the battery can charge itself full but then heat up a little over it's specified limit and thus drain the battery a little, i usually just do quick little charges. Ive heard friends of mine say, "oh i plugged it in for 5 minutes and now its been full for 2 hours." I fully agree with this, it's like zapping someone to life, give them a charge, live for another 10, 20 years, etc... works fine for me. Of course i have a dock, wall, and car charger, i'm very pleased.

If the lithium battery is immune to the memory effects of NiCad and others then why does Apple recommend completely discharging the battery at least once a month? As far as I understand, lithium ion batteries stand up well to abuse, so I was puzzled by this recommendation... And, of course, there is no explanation provided...

400 charges isnt alot IMO..

pretty much every day i run my phone down to 10-12%, so i have to recharge. ive had to recharge twice in a day going that low before.. my battery life sucks imo. but i dont worry to much about it cause pretty much where ever i go i can plug it in.

The iPhone battery life does leave something to be desired IMO... I too can usually plug in my phone wherever I go, but to be honest, I would not mind the phone being a little bit thicker and include a battery that is a little bigger. Battery design on devices such as the iPhone is a very tricky business. At this point, the technological capabilities of such devices are outpacing advancements in battery technology...

I think there's always something that companies won't tell you about some aspect of business. I honestly find iPhone companies and the people who work for them dispicable, especially when it comes
to aspect of repairs.

The iPhone charges very quickly using wall charger. I have read in more than one place that car chargers should be used sparingly as they decrease the life of the battery. Anyone agree with the car charger theory? I personally never use a car charger but I guess this may be handy for people that have driver type jobs.

I heard the limit of the iPhone's battery is 1,000 charges. If you charge so much and so frequently, you can be guaranteed this will reduce the lifespan of the battery.

You cannot overcharge Li batteries. In fact, the battery will last the longest if you keep it charged when not in use.

So dont let it drain down to zero, and charge it every day.

The 1000 charges refer to full charges. So with partials, it should last quite a while.

Of course with all the battery issues caused by the OS....I suspect that many batteries have been damaged and will need to be replaced.

Be mindful of your battery life as your 1 yr warrenty draws near its end.

Not correct regarding life span

Not exactly but it's really not that far from it once you read this...

"Charge Cycles

A properly maintained iPhone battery is designed to retain up to 80% of its original capacity at 400 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs."

And remember, that's just not incremental in it's percentages. Degradation increases with time, so at this rate with 1,000 full charges, you'll be past the point of looking to replace your iPhone. :dft010:smiling
