Why "Home & Lock Screen" consume more than 20% battery life in iOS 8.3?

the apparent main drain remains as the Home & Lock screen at 36%.

what on earth is the screen requiring 36% of life to do? What secret life does it have while it sits in darkness??

Cellular signal is the primary drain for the home and lock screen, after actual screen use. Unless you tell me you have 5 bars, my bet is on your weak cell signal. Note also that many apps run in background when the phone is asleep. However, their usage will be listed under the apps name. Their data usage will not be, however.

Like most of these have said this never happened until the update. I haven’t had this problem either until the update. My battery never got hot and my usage is always minimal. Something clearly they did wrong and they need to fix it. This is why I hate doing the updates and put them off as long as it will let me.

Thank you for using the Apple Support Communities

It is unknown why the "Home & Lock Screen" is using that much of your battery. My guess it could be your widgets in Notification Center or the parallax effect behind your Home Screen icons. My suggestion would be to fill out Apple's iPhone feedback form that way they know what is going on.

TTurning off auto brightness and auto lock to one minute should help. Turn brightness to half or a little less than half helps out a lot. And when you need the screen to be brighter just use the control center. Good luck.

I Was not aware that every generation iPhone was using iOS 8.3. But if you say so.

Immediately after the iOS 8.3 update on my iPad last week, my battery drain was significant. Prior to the update, my battery lasted for multiple days before neededing a recharge and I could play music all day. Now the battery drains completely in less than a day, with little to no use...this is ridiculous!! I have turned off all options, settings that help pages say to turn off, I only have none or 1 apps running. I just checked and my battery usage shows 83% in the last 24 hours is linked to Home & Lock Screen.

I am both delighted to find this thread and also disappointed that there is no solution! I have been into the Apple store where they tell me that my battery consumption is as they would expect. I close my apps religiously yet, when I forgot to take my iphone 5s to work with me yesterday, I had charged it fully overnight and by the time I got home at 5.40pm, it was down to 4% battery. This claimed usage of 25 minutes, standby of 9 hours 48 minutes. Apple support tell me this is good?

I only took receipt of the handset on 11th april. Brand new out of the cellophane.

I am scared to use any app at all in case I lose the basics.

even now, having typed this - it has dropped from 20% to 16%. Just by me watching it while I type on my laptop.

If this is normal, I want my money back!

I did the iOS update to 8.3..........now my iphone 5S battery lasts maybe 2 hours and is almost too hot to touch. I am in utter disbelief that the only "fixes" to this problem......HUGE problem..........are suggestions to monitor and restrict everything I was doing with absolutely NO problems whatsoever, BEFORE THE UPDATE...............you HAVE GOT to be kidding me??!!! Steve would have NEVER let this ridiculousness slide........not for one minute.

The best APPLE can come up with is:

• Shut down all your apps.
• Stop using you phone.
• Buy a new phone.

I'm ashamed and embarrassed . THEY should be.

Closing apps religiously is one possible reason. There is no need to close apps at all, unless they malfunction. Closing apps slows down your phone and increases battery drain because the apps must be reloaded to RAM every time you invoke one or a notification invokes one. See: http://www.howtogeek.com/204552/no-closing-background-apps-on-your-iphone-or-ipa d-wont-make-it-faster/

Another possible cause of battery drain, which is likely based on your 25 minutes of usage, is signal strength and consistency of the cellular signal. A phone with no cellular signal that is left on will drain the battery very quickly, because the phone will keep trying to reconnect at maximum output power. A weak signal will also drain the battery quickly, because the phone (any phone) adjusts its output power to maintain a connection. A "1 bar" signal requires 10 times as much power as a 5 bar signal.

If your usage was much higher, say close to the standby time, the problem would most likely be an errant app. But heavy battery drain with little usage is usually a weak or intermittent cellular signal.

But not having touched the phone all day when it was connected to super duper fibre broadband wifi (between 45-80Mbps) wouldn't have sucked the battery dry. Plus my iphone 4 (which my husband commandeered after he let his own go swimming in a cappuccino - unsuccessfully) didn't have this issue. I am not a heavy user of the phone. I have today deleted ALL apps to try and see if one was causing the problem. No such luck. Having not used the phone since my last post (which wasn't too long ago - 15 minutes?) I am now down at 4%. For it sitting on my dining table doing nothing!

I am not sure if I can return it under the Sale of Goods Act because it is not fit for purpose. Up until now, I have been a HUGE fan of Apple and their products. But they don't believe that this handset isn't fit for purpose. It doesn't feel like an upgrade at all - it feels like a massive downgrade - and I am so disappointed. It's been a bit like going to the doctor with complaints of migraines - and they can rule out reasons x, y and z as the possible cause, but they are can't tell me the route cause - and slowly I am thinking that they don't believe me, that they think I am making up the symptom - or that to get migraines is the norm, to be expected.

And I know that it's not!

Your phone is NOT connect to WiFi all day unless you leave it plugged in, or it is in active use. WiFi is turned off when the phone is asleep to preserve battery. So any apps using data in background will use cellular data.

A phone (any phone) connects to the cellular network frequently so the network can find it. Even when it is asleep.

What is your signal strength?
