can you charge the spare battery by itself, or, do you need to be charging the phone on it simultaneously?

Since there is no light to indicate if the charger is working, it is hard to tell. Also, getting the battery to line up in the cradle is difficult. I also had trouble getting the phone to charge. The unit was too light and so everytime I tried to pick up my phone, the charger came with it because the phone was difficult to pull out from the prongs and the charger stand was way too light. Don't buy this. Wait until they develop a heavier, more reliable charger. It did come with a separate battery charger that plugs directly into the outlet and it worked fine.

it's a charger, it can be recharged... and yes you can use your phone while charging it.Problem with mine- i dropped it.. and it hasn't worked since - I loved it before that happened.

Yes, it can be charged that way too. I tried the charger at first, after an hour the light indicated "charged" but when I started my phone it was only showing %60 battery. Maybe the charger is faulty, but the battery is still working great! I reach %100 very fast while charging. Hope this helps you. My girlfriend has the same phone and I gave her one of the batteries, it didn't work out for her, she says it's the same as the original, I haven't tried out that battery on my phone, plus her phone is really in bad conditions, lots of apps installed and stuff...

Yes you can charge the battery normally via USB. No need to take the battery out of the phone. Works twice as good as my stock battery for my Sensation 4G.

To charge the battery in phone and one on dock @ same time however I would advise against it as it slows charging significantly.

It is rechargeable and depending on device you will be to charge 2 devices before having to recharge the battery. As far as using the phone while charging you should be able to, should be no different than having it plugged into a regular charger.

There is a battery in the case itself and your phone automatically pulls power from that battery when it needs it. The case uses a micro USB cord and will charge both the battery in the case and your phone at the same time. Mine just recharged my phone as I was typing this :)

I think what you are asking is can you charge your phone while charging the battery. Yes as far as I know. I did this back in late August and it seems fine.

You can plug in and charge the battery directly through the phone... It's nice to keep the second battery charged in the wall charger and near by in case you are in a situation that you cannot use the original phone charger (airplane, traveling, etc)

You can charge phone by use included USB charger connect to the charge dock. Or you can take out your cell phone battery and put the battery in the charger dock to charge your battery over night. I put one battery in the charge dock all the time so when I forgot to charge my phone, I always have a spare battery to use.

There is a USB port as well. You can charge one external battery AND your phone at the same time :)

Yes. You set the phone as shown and it charges the battery, and on mine the space behind the phone will charge a separate battery at the same time :) When placing the actual phone you must take the cover off which is not a big deal.

Yes I leave mine in the phone and charge through the normal chargers. I keep a spare charged up and in my pocket in case I need it.

It charges in the phone. . Only if you want to. . I rather have the stand alone charger. So batteries can be charged at home without tying up the phone . Then bring them along as charged spares. For the extended outdoor festivals!!

Yes. It is designed to first charge the phone if it is not fully charged, and then it will maintain the phone's charge while it charges its own battery.

Yes you would just charge the battery with the charger that your phone uses.

Yes you can charge both the device and phone at the same time. The charging device will take prority during charge if the phones battery is low.
