iPhone Bulging Batteries

In recent weeks we have noticed a growing issue regarding the iPhone 3G and 3GS 16GB and 32GB.

What is it and what causes it?

The picture below shows a swollen iPhone 3GS 16GB battery. This is becoming a common issue for most phones that have Li-ion batteries, especially for the 16GB and 32GB iPhone 3GS. A professor from MIT says that “The problem has to do with the chemistry of lithium ion batteries, which reacts unfavourably to overcharging.” Chemical reactions are accompanied by heat released whilst charging your iPhone.  When the battery gets hot, gases within the battery expand causing the battery to swell.


  • The iPhone gets very hot whilst doing normal things, such as listening to music, watching short videos and browsing the web.
  • The iPhone’s battery becomes less efficient – the iPhone loses its battery very quickly after it has been charged fully.
  • The iPhone could also do some random restarts, and occasionally it could even turn off completely and the only way that you could turn it on is if you charge it.

What effects does this have on the iPhone?

The main side effects this issue has on the phone include:-

  • It could push the iPhone digitizer as it swells lifting it up from its original position.  (What’s a digitizer?) This could cause the digitizer to go very dim and exposed to an easy liquid damage.
  • As the digitizer pushed up from its original place, over time it damages the screw at the bottom of the iPhone.
  • The worst impact this issue could do to your iPhone is that it may gradually damage the main board. What this means is that the iPhone would become completely useless as most main board problems are not repairable.
