Welcome to the forums, smrahmani!
I'm not sure what you mean when you say lifetime. Do you mean how long will the battery last or how long the tablet itself will last until it breaks and cannot be used.
Both scenarios have so many varying circumstances that I think it would be really hard to provide data for. It depends on how the tablet is treated and used. To me any device can last for years if used correctly and not abused.
I will move this thread to the general tablet section and send you a PM with the link.
Have a good one, smrahmani!
