The differing reviews for the NewTrent IMP130 hint at the different ways people appear to use it. I'm a power user. Not because I make lots of phone calls, but because I use iPhone apps quite a lot. And some of them are notoriously power-hungry.

Pros:
- great-looking case with subtle rubberised finish and cool blue LED indicators on the back
- iPhone slips into it easily, and after a short learning curve, slips out again easily enough once you have the knack
- iPhone is held securely in place, and the case easily protects from normal knocks and bumps
- one of the slimmest iPhone battery cases out at the moment, if not the slimmest, as far as I'm aware
- a switch controls whether the case charges the phone or not (leave it off to charge your phone in one go, once it's battery starts running low)
- trickle charging mode where the IMP130's battery runs down before the iPhone's own battery
- photo light (well, a bright LED anyway - I've not tested it for photos yet but I doubt it is powerful enough for anything but the closest snaps)

Cons:
- even though it is slim, and will easily fit into a trouser pocket, to me it still feels like a monster in the hand, particularly when compared to the svelte form of the naked iPhone (I can't imagine how bulky the other powerpacks on the market must feel)
- battery capacity (or perhaps the circuitry in trickle charge mode?

AMAZING.

That really does some up how I feel about this product. I hammer my iPhone, I spend the majority of my life on it. I literally would open a tin of beans with it if I could. So as you can imagine the awful battery life of the iPhone really does not cope with my heavy use.

The New Trent looks good, yes I know that is not the first thing I should say but it is important with an iPhone. Such an iconic piece of kit would be ruined with a badly fitting cover. The New Trent is bulky, I always have a cover on my iPhone as I work in a dirty environment and need protection from bumps and scrapes, so it isn't unusual to me. If however you are going from naked iPhone to this it will feel a lot heavier and beefed up. I personally love the "industrial" alter-ego my iPhone has taken on. Well, the main reason of course is the Battery life. The New Trent doesn't fail to impress, not only does it double the life of my phone it also allows me to only charge it when it really needs it. To charge a battery all the time and never allow it to drain down to virtually nothing makes it worse...something to do with electrons, so because I dont worry that I only have 40% battery but I'm going out tonight I just carry on, and flick the convenient on/off switch on the cover when the battery is almost flat. Brilliant.

Charge and sync with the cover on, never leave home without it. After a recent Social media event I have been heavily engaged with, I spent serious amounts of time on the web. Big test. Big success.

Buy it, I am not easily pleased. This exceeded my expectations. Until Apple improve or battery development catch up, this is THE answer.

I've been looking for a perfect case for my 3GS a long time and I have to say this IMP130 is probably one of the best in the market.

First of all, the case really fits with ease. It's also easy to remove the case as well for mounting the 3GS on the windscreen.

In terms of battery life, I've managed to get 50% extra with a full charge.

It comes with an USB cable to charge/sync the iphone without the need removing the case at all. The flashlight on the back of the case comes in very handy for taking a photo in the dark.

The only problem I have with my iphone is the short battery life. Now I have found the answer to this problem - it is the New Trent Battery Case.
It is slim, it looks good, and is really easy to use. You don't even need to take your iphone out of the case to recharge it!.It charges quickly and the 3 blue lights show you clearly how much battery life the case has got. I love the torch on the case and have found it really useful when returning to my car in the dark, and returning home late to see my key into the door lock. The light is surpringly powerful. I rate this excellent value for money and would recommend it to all iphone users. I have found it to be 100% reliable

Quite happy about this product. It feels good in the hand, and while it bulks up the phone quite a lot I don't mind.

Charge extends battery life a few hours, which is good, but one annoying thing is that you can't use your existing iPhone connection USB cables to charge it.

If you use the iPhone 3GS for a lot more than just phone calls, then this is well worth considering. I use the phone with a Thinkoutside bluetooth keyboard to take notes (into Handbase) and do emails, and it's a pain to run of battery. This is simple to fit (and to remove) and if you leave it switched to 'ON' then both phone and battery case get charged up automatically when you plug in, and it then uses the battery case first and then the phone battery. It's easy to check approx battery charge level with the 3 indicators on the back. It's a very snug fit to the phone and feels like it protects it well. However, your phone is no longer that nice sleek looking gadget which is a shame. Also it won't fit in normal iphone cases any more. However, I found the Black Flip Belt Case For The Samsung Galaxy S i9000 Mobile Phone (sold through Amazon by King Of Gadgets) just fits it nicely (slightly tight) and looks far more compact than the belt case sold by New Trent. The charging lead is a bit short, but can be extended with a USB extender.
Overall I would strongly recommend if you want a reliable way to extend battery life. By the way, watch the ON/OFF button - a bit too easy to accidentally switch to 'OFF' and then only the battery pack charges up.
