I have had several mobile phone brands starting with Nokia, Siemens, HTC, BlackBerry and my current one is a Samsung Note 1. Since my note 1 is already 3.5 years old I am ready for an upgrade. What I don't like with modern smartphones (latest version of Samsung as well as Apple) is that you can not change the battery yourself. At an Apple store they even told me to change the battery cost 180 euros which is outrageous !!! So my question to current iphone users is how long (on average) does an Apple battery last when at most charging the battery 2 time a day ? With my current note 1 I have to change the battery every 14 months. Since i replace my phones only after 3 years it can be very expensive if I have to change the battery of an Apple phone 3 times. No I don't want to buy a new smartphone every year (I am not a teenager).
