Wrong board, your in cars and matinence, but here you go anyway.
Calibrate iPhone Battery:
Use the iPhone until it it shuts OFF itself, due to Low Battery. Then Charge it back up without interruption, like unplugging it, to full charge 100%. Then before or after you do this, Reset iPhone, hold both home and power buttons until the iPhone restarts itself, ignore the "slide to power off slider", let the iPhone restart itself.
Obviously the battery was not used up from researching solutions to your dilemma with the search function… Most likely from texting and playing games…
- Will charging my iPhone battery on full brightness increase battery length? If I adjust it to full brightness while charging and once charged 100% adjust it back to a dimmer screen will this increase the battery's life span?
- Will an iPhone 5 battery fit in a iPhone 5s battery? My battery needs replacing on my iPhone 5s but the place I'm getting it replaced only has iPhone 5 batteries, so does anyone know whether the 5 nbattery will work in my 5s?
- Possible to change iPhone battery for better battery life? I'm going to get iPhone 4s and heard it's battery life runs out quickly. Could you buy a better one which lasts longer to replace? Which are best and what is the price range?
- Why battery percentage indicator in iphone is not showing accurate battery? Let its being charged, let it reached 97 percent, it will still showing charging, but if i off/on it, it will show 100 percent, and it shuts off when it reaches 4 percent, please tell what's problem? and as above i said, if i go to "usage" it will show time charged last time:0 mins standby:0mins but at top right its 99percent and is showing charging?
