Which cellphone has better Battery backup...

None. They're all pretty pathetic. Any battery if properly recharged with radiant energy should last forever! There is a popular, cheap & simple way of quickly recharging certain types of batteries to "better than new" standard (with even more capacity than a brand new battery!) that thousands of people all over the world have been enjoying for many years now. Some benefits under certain conditions have also been had with "accidentally" remotely recharging mobile phone batteries. If you want some good advice, take that expensive, environmentally unfriendly, limited capacity battery out & strap a decent wet cell lead acid battery to your mobile phone that can be recharged properly with radiant energy to "better than new" standard each time very quickly & indefinitely - you can pass the battery & charging system onto your great - great grandchildren if you want. Let us know if you are interested & I'll sign you up to the group of thousands of people who have done it before. You don't need to pay them any money at all & they will help you 24/7 to build & test your own unit for free with full support online.

Hello all my cellphones are Nokia, i don't play games, don't hear music or watch video, just talk to friends and family members. If your phone is by reputed brand, and you are using the original charger supplied with it, than there is no fear of any kind. i charge my cell phone every alternate day, i just plug in before going to bed and unplug in the morning, have never faced any problem, the battery is 3 years old now.. Thanks for sharing Cheers. God bless you, have a nice day ahead. Professor ‘Bhuwan’. .
