My Iphone 5S has only half a day of battery life, I cannot record a video by direct download, I cannot store an MS XL or MS Word or PDF directly, I cannot delete a bunch of emails in one shot. My old Blackberry 9700 does all this, and much more, with a battery life of 2 days. I regret having "upgraded to Iphone

I replaced my Blackberry 9700 with an IPhone 5S. In no way is IPhone performance better than my old BB. I cannot record videos, I cannot edit Office files. I cannot delete old emails in one bunch. Battery life is half. The IPhone seems to do nothing

My IPhone 5 would deteriorate in battery charge retention with every software upgrade. Lousy value for money, threw the hideously expensive phone out, got a Redmi, it does much more than the IPhone at 20% of the price.
