And easy instructions on YouTube *by W***W on Reviewed in the United Kingdom on 14 June 2019* If you do as advised and watch the YouTube channel on the specific model you have then this is really easy. A bit time consuming it took me 35 minutes to take out the battery and re-install the new one. And do as other people have advised when it comes to taking the glue sticks out that holds the battery at the back up a little bit with a hairdryer. If you do as advised and watch the YouTube channel on the specific model, then this is really easy. A bit time-consuming it took me 35 minutes to take out the battery and re-install the new one. Monkey Sea monkey do Sort of thing when using there YouTube.And do as other people have advised when it comes to taking the glue sticks out that hold the old battery heat the back up a little bit with a hairdryer.Very worth the cost, if I need a new one I definitely do it again. ### ⭐⭐⭐⭐⭐ Why are you scrolling? Just buy it *by S***N on Reviewed in the United Kingdom on 24 June 2019* -Easy to install (using video)-Long battery life-Don’t need to waste your money and go to ismash and pay £30 or so, just buy this.. cheaper-As far as I am concerned none of my previous batteries lasted this long at all-My phone has been “dead” ie not working or opening after an unexpected shut down for a while. I was about to sell it as a non working phone because I lost hope, but this saved my phone.-If you see this before you go to a store to get your phone battery replaced you are one lucky person, now buy it. ### ⭐⭐⭐⭐⭐ Top quality *by M***U on Reviewed in the United Kingdom on 1 July 2019* It took me about half an hour to install the new battery. The tools pack are just what you need to get the job done. The battery life is longer even than the original battery had when I bought the phone, it shows the extra capacity of this one. From charging twice a day I ended up charging every two day.
