Yesterday I bought my first smarthphone and after playing a lot with it and getting used to the whole new experience I decided to go to bed (with a 100% charged battery). For my surprise it was at 45% after only 11 hours on standby. Is it normal? Or the fact I ended up not charging it to full with the device turned off during the first charge and also halted the charge several times during the first charge may have screwed my battery? I realized my Wifi was turned on during the time it was on standby and I was sleeping (for about 8hrs). Thanks in advance for your help and sorry for the poor english.
