Is this usually how fast a smartphone battery drains?

[Lili DeRochefort]

I have an HTC Sensation 4g. I left it charging over night so that it was at 100% when I woke up in the morning. So when I woke up, I took off the charger and start using it. I was looking at Twitter, and facebook. My screen brightness was set to automatic. 18 minutes later my battery is already to 87%. Is that usually how smartphone battaerys are? Should I replace it?

It would depend on what you have enabled such as wifi, 3G(or 4G), brightness allowed, (if possible) push and fetch for mail, what applications are running in the background, and how long you've had it.

You can make your battery last longer by using yor cellular network and data only when you need it, or using wifi where given, charging it to full when it's almost (almost!) completely drained, such as, around 20% and such. Setting mail options to fetch manually (if your device supports fetch and push) turning off bluetooth, and dimming your screen to an acceptable level.

yes its normal. my battery would be low by the end of the day and I charge mine every day.
