While surfing some Apple Forums and Message Boards this week, I noticed a common recurring theme among the iPhone loyalists: The poor battery life of iPhone 5. Although the observations varied from user-to-user, everyone seemed to agree that the battery life of iPhone 5 isn’t what Apple markets it to be.

In this blog post, I’ll be doing a breakdown of the maximum iPhone 5 Battery Life.

First, let’s start with what we know.

According to Apple, the iPhone 5s and iPhone 5c offer the following in terms of Total Battery Life:

  • 10 Hours of talk time on 3G
  • 8 Hours of internet usage on 3G
  • 10 Hours of internet usage on Wi-Fi
  • 10 Hours of video playback
  • 40 Hours of audio playback
  • 250 Hours of standby time

*Note: All the above values are based on a Fully Charged Battery at original capacity.

Now, those values are what Apple claims the maximum iPhone 5 Battery Life to be. In reality, the Battery Life depends on a number of different factors, which makes it really hard to accurately estimate the maximum battery life for a given device.

Here are some factors that can affect your Battery Life:

Chemistry –

Huh? Yes, Chemistry. Many people don’t know this, or maybe they do, but Batteries are nothing but an Energy Storage Device. They store Energy; more specifically – Electrical Energy. When you take a Battery and start disassembling it, at the core, you’ll find a Chemical Compound – Chemical Molecules – Atoms.

Molecules and Atoms by their very nature, are MORTAL. They have a certain life span, after which they cease to exist. So over period of time, these Atoms and Molecules in a Battery start degenerating .aka. Atomic Decomposition; thus affecting the overall performance of your Battery; which eventually results in reduced Battery Life.

Because of this, no two iPhones – manufactured in the same batch, facility, and around the same time – will have identical Battery Life.

Wi-Fi and 3G Connectivity –

Whenever you connect your iPhone to Wi-Fi or 3G, your iPhone sends a series of packets to the router (Wi-Fi), which in turn responds to those packets, thus allowing you to connect and browse the internet wirelessly. Depending on your proximity and the strength of the signal emanating from the wireless router, your iPhone will have to send more or less packets. If the signal is strong, your iPhone sends fewer packets, thus reducing the response time, which equals a faster internet connection. If the signal is weak, your iPhone has to work twice as much than it normally would, and send more packets, thus increasing the response time, which equals a slower internet connection. Basically what this means is: The more effort your iPhone has to put in to connect to the internet (Wi-Fi and 3G), the more Battery Life it will use to process all this information.

Slower Internet Connection = Reduced Battery Life.

Other factors that can affect your Battery Life are:

  • Background Processes and Open Applications
  • Brightness
  • How frequently your iPhone fetches new data (Emails, Contacts, Calendars, etc…)
  • Location Tracking
  • Vibrate Mode
  • Ringtones and Sounds
  • Etc…

In conclusion, I’ll just say this:

Unless you see a dramatic reduction in your iPhone Battery Life, there’s no need to panic. From my personal experience, the iPhone 5 certainly has an improved Battery Life, than its predecessors.
