Best Battery for iPhone 3

1. Insten Li-POI Battery Replacement for iPhone 3G.

Your iPhone 3 might still be performing beyond expectations but you need its battery replaced. In that case, this 3G replacement battery would be a pretty decent choice.

The Lithium Polymer battery provides you with 1500mAh worth of power at 3.7V capacity. The accessory is compatible with all iPhones that fall within the range of 8GB and 16GB.

One thing with the Insten battery is that it’s quite stable. Once fully recharged, it can last you for up to 48 hours under normal use.

However, as time goes by, the life may depreciate to just under 24 hours. That, however, takes time to happen.

The only challenge with this battery is that it requires technical skills to install. We only wish it came with a helpful installation manual, but it doesn’t.

Otherwise, this is a really great battery.

Pros

  • Long lasting
  • Affordable
  • Light in weight
  • Dependable

Cons

  • Requires a technician to install

2. Vintrons 1200mAh iPhone 3G Replacement Battey.

Certified as safe to use by CE, RoHS, and ISO90001, this battery is designed to stun. In fact, it’s meant to be used on iPhone 3G 8GB and 16GB phone models.

Sometimes that’s all the power you need to keep your device stunning. Most importantly, this unit provides you with 1200mAh power. On average, that should be enough to last you for slightly over a day.

That said, we still think that 1200mAh isn’t that much. Therefore, you’d be better off limiting your browsing habits to get the most out of this battery.

Otherwise, we like the fact that it’s pretty light in weight and highly compatible with all phones of this model.

Pros

  • Compatible with all iPhone 3s
  • Certified as safe for use
  • Affordably priced
  • Well-built

Cons

  • Limited battery power which also declines over time

That’s enough power last you all day long. We’d have wished for more power but the good news is that iPhone 3s aren’t power guzzlers.

They do a good job when put to a minimalistic use. So, if you aren’t an intensive smartphone user, we think this replacement battery would suffice.

Pros

  • Relatively easy to install
  • Shipped fast
  • Works pretty much like an original

Cons

  • Sub-par warranty coverage

The Exogear is one such case. Beneath it is a superb, 1300mAh lithium-ion polymer battery. Therefore, it doubles up as a case and a backup battery as well.

The Buying Guide

What are some of the factors to keep in mind when shopping for an iPhone 3 device? Well, our criterion is short and simple.

First, the battery should be available on the market. That’s because new iPhone brands have taken over the market and, therefore, very few companies are producing replacement batteries for iPhone 3s.

Besides that, you want to make sure that your replacement battery is properly screened for safety. Therefore, consider going for a unit that’s at least CE and RoHS certified.

Another important factor to consider is the level of power provided by the unit. Ideally, you should only settle for a phone with at least 1200mAh.

That way, you can get enough power to run your phone throughout the day without the need for a recharge.

And as we sum it all up, it’s best to invest in a phone that has a warranty. The longer the warranty period, the better the battery is likely to be.

Which One Is The Best?

We’d go for the Insten 3G Cell Phone replacement battery. Armed with over 1500mAh power, this is the best bet for long-term performance. Most importantly, the battery is pretty easy to install and compatible with all iPhone 3G phones (8GB and 16GB).

Final Thoughts

A good replacement battery can breathe new life into your iPhone device. However, in order for that to happen, it’s important to make sure that you only settle for the best picks available. Luckily, the detailed reviews above are meant to help you make that decision today, without compromising.
