I was skeptical. But I try to try new things before posting negative comments about it. So this morning when I got to the office I bump charged battery.
7 hours later I have 68% battery remaining.
I have also set my screen brightness down to 20% and turned off any syncing I don't need. But even with these settings I was usually at 45% after 7 hours. I would say the bump charge made a significant improvement.
If you don't know what it is...charge phone till led goes green. Unplug phone. Turn it off. Plug phone back in and wait till led turns green again. Unplug phone. Turn phone back on. Plug it in again till lead turns green again. Un plug it. Turn it off. Plug it back in till the led turns green again. Unplug it. Turn it back on and plug it in again. When the led is green again...enjoy. the last time it should charge to green led a lot faster than the first couple times. If not...do it again.
