If I charge my iPhone with my laptop will my laptop battery drain faster?
Yes it will. The effect will not be massive, but it will likely be noticeable.
No, because there's such a thing as a free lunch
If your laptop is plugged in it won't cause the phones power source would be your laptops power supply but if you're laptop is not plugged in it will drain quicker cause its power source it the battery in the laptop

"Also, a USB port can only supply a max of 200 mA whereas most wall chargers can provide up to an amp. Although this means the wall charger can charge the phone faster, that also makes it less efficient - more heat is produced in the battery and in the phone's charging circuit when it's charged faster. "
"Most "wall wart" phone chargers can put out 5 volts at 1 amp. In DC, and loosely speaking in AC, watts = amps x volts, so that's 5 watts."
"Laptop Computer: 15-45 watts"
All together, we have the laptop consumption of 15-45 watts, plus charging the iPhone 1 watts (0.2 amp * 5 volts = 1 watt), so a total consumption of 16 - 46 watts.
Charging the iPhone will use between 2% (46/47) and 7% (16/15) more battery (energy).
- Battery on my iPhone 4S doesn't fully drain? My battery life is weird instead of draining all the way down to 1% it dies at around 12%? What can I do to change this? Or improve battery life overall?
- Should I completely drain my iPhone 5c's battery before first charge? I've just got my brand new iPhone 5c today and it came with about 90% battery when I first turned it on. I'm now on it and it has 55% charge. I'm wondering wether I should drain the battery to 0% then fully recharge it to 100%, that's what used to be recommended but I'm not sure if you still have to do it. Will you please let me know what I should do. I will get to sleep in around 2 hours, FYI.
