Here I am in 2019 with an iphone that only lasts a day or less on 1 charge,(reply>), How does it go on two or more charges?,(reply>), You think your iPhone is bad. At my workplace the forklift that I use on a day-to-day use need to be recharged during the night and lunch in order for me to get through the day's work. And a forklift battery is massive (the forklift battery is about 75 to 80% of the weight of the machine).
