Home & Lock screen battery usage 47%

Question

Iphone 5 IOS 8.  In checking the new features on IOS 8, I noticed that the Battery Usage for Home & Lock Screen is 47%.  Battery replaced on 09/12/14.  Is this normal?

Answer 1

I have been having this issue off and on since the 8.0.2 update. I seemed to fix it, then 8.1 brought it back... thought I got it in order again, and mostly, it runs ok..then suddenly the battery just drains like crazy! Granted... my phone is about a year old, so probably is about time to replace the battery anyway... but it's this unpredictability that is bothering me! I almost have to keep it plugged in at night now because I use it as an alarm clock, and a couple of times, the battery has nearly totally drained within just a few hours of sitting there! Last night, I know I looked at it in the middle of the night and it was at about 85%, but then this morning, suddenly, it had dropped to less than 10%! Same thing earlier this week. It was sitting on my desk by my computer and it had been fine and suddenly the insufficient battery symbol was flashing! If it were just the battery going bad, I would have expected it to consistently drain, but it seems fine some days.
One thing I did consider is that we have some apple charger cables and some cheap, third party ones....and sometimes it seems that, while they seem to charge the phone, that the charge doesn't hold as well... but it isn't consistent either. I do know that the colorful ones target sells are NOT good! they cut off some of the sound when plugged in (video, text alerts etc), and if you try to use it as a data transfer cable to your computer, the transfer seems to get stuck.
