Hi Simon, The iPhone 5S has a slightly larger battery than the 4S, the 5S battery has a capacity of 1,570 MAH whereas the 4S battery was 1,432 MAH. Also, if your portable charger is several years old and has been used a fair bit it will have lost some of its capacity to hold a full charge. You have to decide how large of a battery you want, e.g. how often do you want to be able to charge your iPhone 5s back to 100% once it reaches the first low battery alert at 20% and would you sometimes run it way down to 5% or less before you charge it. If, for example, you typically charge it when it reaches 20% and you want to charge it twice, I'd recommend at least a 3,000 MAH battery, a bit more is safer. Keep in mind that nowadays batteries around 3,000 to 5,000 MAH are not so different in size, if you just want a battery that is as small as possible and which let's you charge it back to 100% a 2,000 MAH battery is probably sufficient. I highly recommend the Anker external batteries. I just bought a 5,000 MAH Anker "PowerCore" battery from Amazon.ca for $25.99 with free shipping. It is a round cylinder that is about an inch and a quarter in diameter (3.3 cm to be exact) and 4 inches long (10.8 cm). It has a bit of weight to it, but like all Anker products it feels very solid and well made. If you know what a large D-Cell battery feels like you can picture it, a D-Cell is 3.3 cm by 6.1 cm so this Anker battery is exactly the same diameter and at 10.8 cm long it is not quite as long as two D-Cell batteries end to end, to be exact is is 1.75 the size. Anker claims it has the best size to capacity ratio of any external battery, here is a link on Amazon.ca:

I need some help! I need to find a new battery charger which is portable for my phone, the one that I have right now only charges 70 or 80% of the 5s phone, whereas when I charged it to my old phone for S, it charged all the way to 100 percent.
