Battery stay at low level even after charging overnight?

There are some phones with higher current need, for example iPhone 3G and 3Gs, HTC Hero and Magic, Google Nexus One, HTC HD2, Samsung Omnia i8910, and Motorola Milestone. GeekTechPost.com

Sometimes you are might just be able to charge to around 50% – 60% of full battery, chances are you are using a USB hub or a bad AC adpator.  If so, you might need to use the original AC adaptor.  The rational behind this is that it cannot charge fully if the input ampere is lower than the requirement of the phone.  This way the electricity cannot be flowed to the phone and thus the phone cannot be charged.

Next time when you buy an AC adaptor with USB out, remember to check the output of the phone – a 500mA adaptor is unlikely to fully charge a phone which requires 1A input(1A=1000mA). GeekTechPost.com
