A lot counts on just how deeply the discharge has actually been, and also are you utilizing outlet power or a computer system USB port for power? If it is on the outlet you could attempt charging more typically, and over-night, so you do not discharge as much prior to recharging. Deep discharging is actually not excellent for Lithium-Ion batteries; research studies show a discharge to 50% and then recharge gives 4 to 5 times the cycle life of a battery deeply discharged all the time.

For a prediction you should know the power rating of the AC charger and also the capacity of the Ipad battery.

For my Ipad Mini it took 150 minutes from 44% to 100% through a brand also new battery. The charger is rated as 5W DC yet actually takes about 7W with pedal to the steel.

A healthy 16Wh battery through a 5W charger takes approx 260 minutes to charge from 0 - 100% - about 4.5 hours

Here"s a Ipad Mini battery charge test.

From what I"ve watched in thes forums the moment ranged fro around 6-8 hours. If ytou are using it while it charges, it will certainly take longer.

The quickest method (and really the just way) to charge your iPad is through the had 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, once attached to a computer with a high-power USB port (many type of current Mac computers) or via an iPhone Power Adapter (5W). When attached to a computer via a conventional USB port (2.5W, the majority of PCs or older Mac computers) iPad will charge very slowly (however iPad indicates not charging). Make sure your computer is on while charging iPad by means of USB. If iPad is associated to a computer system that’s turned off or is in sleep or standby mode, the iPad battery will certainly continue to drain.
