Fitted the battery within around 10 minutes, left the phone to fully charge before using the phone. I haven't had any problems with the battery and I've had it in my phone for a month now, definitely noticed that my battery lasts longer. As the old battery had been in my phone for 2 years would deplete so quickly. This has brought a new lease of life to my phone highly recommend before you upgrading an already decent phone.

So far I have been very pleased with the replacement battery and the tools supplied. It took me ten minutes maximum to change the battery using the instructions in the link attached: https://www.ifixit.com/Guide/iPhone+4S+Battery+Replacement/7111
The only problem I had was separating the original battery from the tape/glue holding it in place - it makes a bit of a disconcerting noise as you prise it off the glue - it is very simple but sounds bad! The new battery fits easily, two screws needed to replace into the I-phone and then the case has two screws to put it back together.

I charged the battery the first night and disconnected. In the morning the battery was flat. I thought I had an issue, I recharged until max and the battery has held a charge showing over 50% charge after a full days use. My original was going flat in 6 hours after several years use.

This is a very simple kit to use and the battery works well.

I have been using this replacement battery now for a few weeks and it is giving consistently better battery life than the 2 year old Apple battery it replaced.

Swapping the old one for this was a heart in the mouth few minutes - being aware that a simple slip could ruin my phone sharpens the mind...

Having said that, I somehow managed to end up with a spare bit (seriously) but no problems ensued; it looks like I was lucky on that score!

Overall, I wish I had replaced my battery sooner as this is a low cost and easy solution for faltering battery life.

Battery and tools arrived quickly, worked perfectly and the battery has performed excellently for the last two weeks.

My tip would be the tool that opens the phone screws has a magnetic tip. But the tool that is for the two tiny crews which connects the battery does not. Therefore loosen off the two battery screws with the non magnetic tip tool, then use the other to lift the tiny little battery screws out and back in place again when ready to fix them in. Losing these either within the phone or on the floor etc would not be my idea of fun!

Not a new battery. Manufacturing date of 2012 with obvious signs of wear and tear. What is the point of replacing an old battery with one that may be equally old or even older? These people are cheats

A suitable replacement battery for my 4s, took several chargers before reaching peak performance (this is normal). Reasonably easy to fit though you do need good eyesight.

While fairly straightforward to install albeit a bit fiddly, it was clear that the battery wasn't new as advertised and performed just as badly as the used battery it was meant to replace: 1) when I interrogated the phone using iBackUpBot on my laptop it showed that the battery had already been through over 370 charging cycles and that it was unable to reach maximum charge 2) within 24 hours of usage (and 3 x full charging cycles), the phone switched itself off at 40% charge.

Overall would only recommend this as a cheap replacement for a completely dead battery, but not if you're looking for an improvement over an existing battery.

The actual procedure for replacing the iPhone 4s battery is simple to follow: undo 2 screws to open up the case - undo 2 more to disconnect the battery clip - lever out the old battery and remove along with cable and clip - insert new battery and reassemble in reverse order (not forgetting the fiddly little earthing tag which goes under the right hand battery clip screw). The snag in the whole thing is that the screws are the tiniest you will ever have seen. I had to work with an illuminated magnifying glass and a pair of fine tweezers to handle the screws which do require use of the 2 specialist miniature screwdrivers supplied. Take your time and prepare a safe place to put the two sets of screws which are not identical. Some reviewers emphasise how little time it took them, but the key thing is to relax and do it properly. Instructions are not supplied with the kit which seems strange so I docked them a point and read through a couple of the many sites on the web/u tube which tell/show you how to do it. The operation was successful and full battery power is restored to my 4s. Reccomended.

I'm so unhappy with this product. I bought off Amazon rather than eBay because I wanted to ensure I was buying a product of good quality but I obviously didn't get this.
When I first installed the battery I was really happy - it was a great improvement. The phone would charge fully and last a lot longer than the old battery etc. Though after a few weeks I started noticing that my phone kept crashing and then after a couple more weeks the phone would crash (not even with low battery) and not turn on again for at least half an hour.
My phone is now completely knackered and I've been told by an iPhone specialist that it is most likely due to this battery. My phone will not charge properly, it often becomes stuck in a loop of turning off and turning on (where you see the Apple logo), and when I finally manage to get the phone turned on the battery says it has 100% and drains to 1% in a couple of hours.
So disappointed. I DO NOT RECOMMEND.

I have been really surprised at how well this battery has performed it is far superior to the original and even lasts longer than apple's product specification for the iphone 4S, I can get it to last 2 whole days on half brightness with wi-fi and cellular switched on. I wish I'd bought this when I first got the phone. Tool get is perfectly adequate and the battery is incredibly easy to fit. I would recommend to anyone with a dying 4S battery and I have even suggested it to my friends who have this problem.
