Someone needs to adress this, the imvu mobile app is so badly optimized 3d wise that it sucks all the energy in any med-low spec phone with less than 5000mAh battery in less than 2-3 hours.
If I wanted to stay stuck to the energy cord on the wall, or next to the energy outlet I would just use a laptop or PC.
It's the worse drag when you travel, you have to decide if you actually need your phone in case you have an emergency or you can stay with your external battery always at hand in order to avoid always being in the situation of "Sorry guys, I have to leave, my phone is on it's death bed because of imvu".
I've seen graphic intensive mobile games that won't suck up that much electricity as imvu does.
