The Samsung Phone Extended Battery and Back.
While most phone manufacturers delight in offering thinner and lighter phones, some users, me included, simply want more battery life. This is the best answer I have found so far.
I always carry a 4400 mAh power bank that can charge all my mobile devices, and since an embarrassing episode in Melbourne a couple of months ago, when it’s charging cable broke, I have been looking for alternatives.
I am currently using what I think is the best option for me, as a Samsung Galaxy S3 user. The S3 is old, but it works, does what I want, and I have heaps of accessories for it. And there are two of them in my office, so sharing accessories, advice & batteries is common.
I am now using an add-on battery that is 4500 Mha, almost 2.5 times the capacity of the original. It comes with a curved white back to replace the factory back. It adds weight, about 35 grams or 1.23 ounces, and gives a slightly pregnant look to the phone, but fits well and looks fine. Having lived with the original Motorola Brick phone weighing 0.8 Kg or 28 ounces, I will not complain about the weight. It is about one third thicker, and about one third heavier, and for twice (or more) the battery life, that is a good deal.
The phone stays the same width and length, and uses the superb Sony charging controller, with a constant 870 mA charging rate. It also protects the camera better than the original case. Since the battery fits in the normal battery holder, it will not interfere with the antenna, but does not have the NFC (Near Field Communication) chip fitted. I have never used NFC, but to some users, this will be an issue.
It will not be a permanent fixture, but whenever I travel I will switch to this two day battery for some peace of mind. This is one of the true benefits of using a phone with a removable battery. Some phones, notably, but not exclusively, Apple devices do not have this option.
I am not, and may never be an iPhone user, but I know that many users of this “thin, jewel like, bla, bla, bla” phone look first for an add-on battery. A search for iPhone battery case returns 41 million results… Mac World says: “The iPhone 5’s battery life isn’t bad, but it isn’t awesome, either. With careful use, you can make your iPhone’s battery last all day. If you want to work your iPhone hard, however, particularly when you’re traveling or otherwise away from places to recharge the device, you need a battery case.” The recommended cases cost $80, $100 and $120. and a benefit described is that most cases use a Micro-USB charging port,not the more expensive Lightning cable. And everything else uses USB charging, so you can share a charger. The power case makes the phone not only thicker and heavier, but wider and longer, and must play havoc with the notoriously problematic antenna.
Other phones by different manufacturers have the same problem. For some, it is to reduce weight and size, for others, it is a cost saving measure.
The result is that public power outlets are at a premium. I was amused when passing through Melbourne airport a last week to see five people huddled around power outlets, even sitting on the floor talking on their phones while they charged them.
So if you travel, and have a phone with a removable battery, check out the options for your device.
