iPhone 4 Battery Replacement

The iPhone 4 I’m using is a company one that I inherited from someone that left the company about a year ago. I jokingly mention that I have one of the first iPhone 4 phones sold in Germany, and I may very well be right.

The latest issue is the battery, which lasted with normal business use no more than about half a day. Not often a problem, as I usually have a chance to top up during the day, it did put me in a situation of having to call or check emails and not able to more than once.

When I read that replacement LiPo sets, complete with tools, run no more than 10€, I opted for one, having thought about getting one of those battery cases that make your sleek iPhone look like a brick (but at least run for more than two days).

When the ordered (and paid-for) kit didn’t arrive even after being a week late, I contacted the seller, who promptly sent me a replacement - that’s what I call service, thank you alltrade-online on ebay.de!

The kit arrived a few days later and I found some time today to do the deed. Luckily, there are plenty of instructions on doing this on the web, though with the iPhone 4, replacing the battery really is a no-brainer. Had I worn my glasses (I’m far-sighted), I probably would have been done after 5 minutes - with fiddling with the screws a bit in the end, I ended up taking 10.

The phone works, the battery charged to full. The next few days will show what difference a new battery makes, I’m quite excited.

What really threw me was this: I’d put the phone in airplane mode before the “operation” (or rather, it was that way from the previous evening). I figured when you yank the battery on an iPhone, it should be better than doing a reboot, after all, the power is gone for a few minutes.

But not so! No request for a SIM PIN, it found the carrier seconds after switching from airplane mode. And, even more bizarre: all the apps that had been running before where still there in memory! Very weird.

All I can say is: if you have an iPhone 4 with an ailing battery (and there is no way it won’t be up for replacement if the phone is 2 years old or older), take the plunge if you haven’t already, and order a battery kit. If you’ve done any sort of tinkering with devices, replacing the battery should be a snap without bricking your phone.
