iPhone 5 Battery Charging

Hi jackk088!

I have found a couple articles that might help you with some of your questions about battery usage on your iPhone. The basic article about the batteries in Apple devices can be found here:

Apple - Batteries

There is also an article about iPhone batteries specifically, and that article can be found here:

Apple - Batteries - iPhone

These articles should be able to provide you with the information you are looking for. Thanks for using the Apple Support Communities!

You can always use a third-party way of replacing the battery.

If you perfer to replace it yourself, here is a Step by Step instructions on how to:

Just becareful about most third-party replacements. If you use an unauthoized store, it could VOID your iPhone and no support will be given after.

As for me, I always use iFixandRepair:

-Recharching your battery when <20% full just once a month can lengthen battery lifespan.(FULL CYCLE)

-Recharge whenever power is less than 100% full and greater than <20%-FULL (PARTIAL CYCLE)

Usualy let it run down once fortnight untill phone warns you battery is very low ( about 20% ), then give it a full charge to 100% and about 30 mins longer.

I have the same question. What is "completely running it down" mean? Is it mean using the iPhone util it shut down?

So no one is being clear in answering the question...
Should i only put the phone on charge when the battery is dead? Should i charge it up to 100% whenever i can?

In the context "improving battery lifespan" and "optimizing battery usage".
