Apple iPhone capacity is up according to Apple but how much exactly
Apple says the new iPhone 5S has improved battery life. You may have spotted there was no information on the battery life in the day of unveiling of the iPhone. This is because Apple never really wants to reveal the battery life of their device for whatever reason. They instead of telling the amount of mAh, go for percentage of improvement compared to the last iteration of the i-device.
This information may be satisfying for you, however, by using a simple formula along with the data on the FCC it is really easy to find the mAh-s behind the iPhone.It seems that the Apple iPhone 5S and the Apple iPhone 5c have about 1570 mAh. If we compared this to the iPhone 5 this is 9% improvement, because the iPhone 5 had 1440mAh.
However, the iPhone 5C seems to have only the modest 4.7% battery improvement.
To really put that into perspective we should make some comparison and make some things clear. The Samsung Galxy S4 had the amazing 24% (2100mAh → 2600mAh), compared with the S3, while Sony Z1’s went up an even more impressive 29% (2330mAh → 3000mAh). Which is absolutely fantastic, but there is also another thing.
It would be unfair to compare phones that are more power-hungry while the iPhone is more effective at using the provided power. This is because both software and hardware working smoothly together. Also you should know that the best way to compare the iPhone with another device is to look at the standby time or the time in use in both of the devices as this is what we are really interested in when we talk about the battery and making improvement to it.
Overall, we should wait until the iPhone 5S comes along and someone will just buy the device and use it to check it up for how many hours the device is out and this is how we decide on whether te thin is better or worse based on some search.
