Yes It is

  • Why is my Iphone 5 Battery Life so bad lately? My Iphone 5 has recently been getting very bad battery life. The only things that I have changed have been setting my email to push as well as resetting all of the phones settings. Would the email really hurt my battery that much? I took a shower today for 15 minutes and at first my phone was at 94% and when I got out, my phone was only at 98%.It used to charge so fast and I have no idea what is going on. Please let me know.
  • What is the difference between and iphone 5 hard case, skin, and hard case skin? I'm looking for a nightmare before christmas case I was looking in amazon and i would see skin and hard case skins. I honestly do not know the difference of a case, skin, and hard case skin in protection and cover. Tell me if one covers the back only, front only, or both
  • My iphone 5s had low battery life so i ordered a new battery and replaced it? But still the battery life is same as before even if its new one… Could the phone be probelmatic? Also my sis gave me an iphone 5 and its battery life is way bigger… Could i take the battery of 5 to take it on 5s?
  • Is the iPhone 4S battery life that bad? I got mine today and I don't see why its so bad. When I got it, it was half charged and I was texting on it a TON and the battery lasted for 4.5 hours. Then, I charged it to 100% almost five hours ago and I was on the phone for 1 hour and 45 minutes and I've been texting non stop and the battery is only a little half gone. Does it get worse over time?
