    Hi guys,

    I just got a camera grip and I charged it fully and then inserted my lumia 1020 to see how much charge it could give me.

    The phone was at 47% and after charging it was at 79%. This is a 32% charge increase which translates to about 640mAh.

    The camera grip is rated 1020mAh. So is this efficient really? Or have I got a fault camera grip?

    Need advice soon

    Thank you

    That is normal. Consider that the phone is running while it is being charged, so part of the 1020mAh is consumed in powering the phone while the remainder is used to charge the battery.

    In fact, when you begin taking photos and videos with the camera grip attached, you may not even notice any significant increase in battery charge - simply because the phone is consuming more power when taking photos and videos.

    It does add time to your use. I use mine when traveling and it helps a lot when taking lots of photo.

    Ditto when traveling. I use the camera grip to get more time and better stability for pictures. I take a fully charged phone and camera back for a full day of picture taking.

    None.

    Mine stopped taking a charge after a couple of months. Got it replaced on warranty. Once again, stopped taking a charge after a couple of months. Put it in the closet and haven't touched it in half a year.

    Did you use your grip frequently, to the point that it got completely drained numerous times?

    That's the problem with Li-ion batteries - they can't be drained completely, otherwise we risk killing the battery permanently. This is the reason I've decided to get a battery pack instead to extend the battery life of my L1020. Whenever I have to use the grip (as a tripod mount), I still keep it connected either to a charger or a battery pack. It defeats the purpose of having extra juice in the grip, but as a result my grip is still working after 1.5 years.

    The weak point wasn't the battery itself, I believe, but the usb connection point.

    30% is about the same I always got.

    A strong candidate, but continuing along this line would cause us to deviate from the main topic.

    My fully-charged grip will charge my 1020, when it has auto-shut-down, to 42%. That's always been enough for my needs; and, the grip will generally re-charge prior to the next 1020 shut-down.

    BTW, Chintan: Mathematically, a change from 47 to 79% is a 68% "charge increase", not 32%. I don't know if this affects your "translation" calculation. Enjoy your 1020, in any event.

    This is mathematically correct, since the implicit basis for the calculation in your example is 47% ((79-47)/47). So, more accurately, a charge change from 47% to 79% is 68% with reference to 47%. But to make comparisons between devices easier, it's better to simply refer to the difference in charge instead of the percent increase in charge.

    I did state the mAh that charged, maybe that's a better indicator. 640mAh charged using a 1020mAh camera grip. 380mAh lost as heat?

    The 380mAh was most probably used to power the phone up (as opposed to heat loss). Although the over-all energy balance suggests that some energy must be lost through heat (since there is sensible heat loss), that amount of loss won't be as large as the energy requirement to power the phone up.
