iphone battery

My iPhone 4 does have a percentage setting. Go to Settings/General/Usage and you'll find an option to display battery percentage.

Did you find it?
 
It's annoying the iPod doesn't have it. If you jailbreak you can have the percentage just like the iPhone. You can also have HDR and a proper iPod app instead of the music and video apps...
 
Yeah, about the percentage of battery usage.... I turned mine off. Keeping the percentage available for viewing prompted me to look at the dang percentage constantly to check on battery drain. No joy there. Turned it off and no more worries!
 
i just read an article that teach you how to make your battery better, but it for laptop. anyone knows how to do with phone battery?
 
The same process applies to the battery in a phone. Let it completely discharge then recharge and repeat the process.
 
Above comment is correct (except you only have to do it about once a month). However, it shouldn't matter too much. Your iPhone battery will be fairly consistent about usage time for about 18 months anyways regardless of your charge cycles.
 
Do not let the battery of the iPhone to discharge all the way NEVER! It is lithium battery and that would be the wrong way to do it. Use it just regular and that it.
 
Hey guys looking for some repair help here. I have a 3gs 16gb that I have been having charginng issues with. I manuelly took out the battery and charged it to see if maybe I had a bad battery, but it is completely fine. When I put the charged battery in the phone it fucntions perfectly. When I plug the phone in it says it is charging but the battery still drains. When dead it shows the plug into charger syrabol and then when it is plugged in it chimes and shows it is charging but will not gain any power..... Have heard something about a power ic but no nothing of it nor where i can get it in the US. Someone please help thanks
