In order to get the best use out of your iPhone battery it is well advised to fully charge it (called conditioning your iPhone battery) prior to first using your iPhone battery.
By the way there is no way that charging your battery for a super long time will add more amps to your iPhone battery. That is silly. Volts and amps are set designs from the battery manufacturer.
The iPhone stops charging once the battery is full. Never run your iPhone battery all the way down; actually the iPhone will shut down before it happens. Also don’t leave your iPhone battery uncharged for days on end as you could shorten your iPhone battery life.
For best iPhone battery life results, try not to use computer ports to charge your iPhone – there may be a charging icon displayed but might not be adding much juice to your iPhone battery.
iPhone’s have built-in, rechargeable lithium-ion and or lithium polymer batteries.
It takes about 3-4 hours to fully charge an iPhone battery. Charging the battery may take longer if you’re using iPhone as it charges.
The best way to charge your iPhone is to use your iPhone power adapter.
There is no need to “prime” your iPhone battery. Just charge it until your battery indicator reads full.
You don’t need to empty (completely drain) the battery before charging it. Lithium-based batteries do not have a memory loss, as seen in nickel-based rechargeable batteries.
Your iPhone battery stops charging when it’s full. Leaving it connected won’t charge it any more or add more power to it. And yes you can leave it. It’s perfectly fine to leave it connected so it can charge overnight.
The nice thing about lithium based batteries is that you can charge them whenever it’s convenient. So charge your iPhone when it suits you, you won’t hurt it.
Your iPhone battery will maintain a charge for about 1 month without being used. After a month of non-operation you may find that the battery will not be at its full capacity.
Why because even when your iPhone is not in use the iPhone uses a very small amount of battery power to maintain the integrity of the overall system.
Regarding your iPhone battery indicator, understand that the indicator is a mere approximation of power available.
All rechargeable batteries have a limited number of charge cycles and will eventually need to be replaced. iPhone battery life will vary
Battery life and number of charge cycles vary by use and settings. As with other rechargeable batteries, you may eventually need to replace your battery.
Lithium based batteries can be charged a finite number of times, as defined by charge cycle. A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean using it during a single charge.
Here is an example of 1 charge cycle: you listen to your iPhone for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle.
Every time you cycle your battery you will diminish the battery’s capacity. Battery cycles on lithium based batteries will range from 300-500 cycles.
So you will get quite a bit of use out of your iPhone battery before you have to buy a new one.
