Too much charging? - Page 2

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.
