10 - 30 minuten
My phone is over 3 years old and my battery would die after a few hours. It usually would turn off after about 4 hours and the battery said it was at 53%. I was worried about trying to replace the batter because Verizon said it couldn't be done and I didn't want to mess my phone up. I bought a $100 external battery charging case. After a few months, even that started dying within a couple of hours. It got to the point where my case and phone were dead by lunch time everyday. I decided to give it a shot. I watched your video on how to replace the battery and put in the order. Three days later I had the batter. It took about 8 minutes to replace it and my phone turned back on just fine.
Flawless. It took 8 minutes from beginning to end and my phone was back to normal. I didn't lose any information, pictures or anything. Now my battery lasts all day long and I can actually use the whole battery. I ran it all the way down to 1% after 16 hours before putting it on the charger.
Don't rush. Use a set of tweezers or something to grab and move the little screws. Put each screw in a special spot so that you don't get them mixed up. Keep an eye out for the little black piece by the top screw from the battery connector. It will probably pop out and there is no special extra careful way to put it back. Just do it and it will be fine. Be smart and it will be over in a few minutes. You WILL be happy you decided to do it. Don't listen to the sales people in the phone stores that tell you it can't be done. You DO NOT have to buy a new phone for $300 dollars. Just spend $25 and have your current phone back to new!
