@jammbuster - Thanks for d advice. I would definitely think about it. Any particular model in mind?
Wow 5000mAH battery. That would do some job atleast. The only concern is d screen size.... i will have to check it out. Thank you for the suggestion Sir.Moto E4 Plus (Best fit heavy battery)
32GB ROM/3GB RAM
Screen - 5.5 inch (Don't worry about half inch as these days mobile sizes are equal to 5 inch of 3-4 years earlier models)
Dual SIM (nano+nano) dual-standby (4G+4G)
5000mAH lithium-ion battery
Motorola G5 is also there but battery is 2800 mAh only.
5.2 inch screen
Moto G5 (3GB, Fine Gold)
