Hello,
Recently I noticed that the battery on my tablet doesn't seem to last very long after being fully charged. I remember seeing that the fully charged battery is supposed to last for around 4 hours, but I'm lucky if it lasts for half of that and sometimes it's even less.
Is there anything I can do that doesn't require replacing the battery? Or is that my only option?

If the battery is no longer holding a charge, it may be time to purchase a new one. The A909 takes 3.7V 4000mAh batteries.
If the battery is completely depleted, charging it through the USB might not work. AT this point, only plugging it into a wall socket will achieve any results.
More information is available on the troubleshooting page.
