I've recently bought a Arnova 7b G3 and after opening the box I immediately used and install the applications without even charging it first. Now the battery easily gets drained. Is there anyway to make battery last much longer?

I remember that on batteries from older technology such as Nickel Cadmium (Ni‚ÄďCd) it was recommended to make a full charge followed by a full discharge to improve the battery life. I don't think this is valid or necessary anymore on newer batteries like Lithium Ion (¬†Li-ion) batteries.

How much battery life are you getting ? On a continuous video play, with Wi-FI disabled and brightness at 50% we usually get between 4 to 6 hours depending on the tablet model.

Cheers.

With continuous playing and downloading some apps, around 1 1/2 to 2 hrs. Just like today I charged the tablet for more than 12hrs and I've only used it around 20-25mins and its already showing 29% on the battery meter.

This sounds like a defective battery.

We have no Arnova 7b G3 to test here, maybe other 7b G3 owners can share they view on the battery life ?

i have the 7B G3 for a while now and i have noticed this battery being drained quickly too for only about 2 hrs use.but i tried lowering the brightness and turning off the wifi and it last a little bit more. And its true charging it usually takes a while until fully charged.

Does the battery meter of yours turns green when fully charged? Because for my arnova, even if I charge it for more than 12hrs the battery meter is still yellow.

Thanks for these tests and numbers Wink 

Do you mind doing it again soon with my battery benchmark application ? (I'll give you all details on how to proceed)

I think there's nothing we could do on this. For the Arnova tablet that I bought for my Mom, she told me that when she's using it, if its fully charge about 23mins or less the battery runs out. Big mistake for not charging 8hrs before using it....

I'm not a specialist Wink but I don't think, that today's LI-Ion and Li-Po used on our devices have an important "memory" effect, so you shouldn't ruin it if you don't fully charge on first use just after unboxing... 

If 23 mins is the full battery life, there's definitely a problem with the tablet.
