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

Hi, I also got the battery issue after upgrading to the iOS 8.3.

My battery will drop from 100% to 30% within 4 hour battery usage (you can find this is the data in the Settings->General->Battery Usage->Usage)

When I go to check the battery usage of each app, I see "Home & Lock Screen" use 23% battery within 24 hours.

I just dont understand what does "Home & Lock Screen" do basically, and why it consumed so much battery usage?

Anyone has idea or the similar situation?

I'm using iPhone 5s

iPhone 5s, iOS 8.3

p.s. how rude of me - thank you for your replies so far! I do appreciate them (now down at 2%) :-) (sorry, make that 1%) (and now off!) (drains quicker than I type!!)

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.

How to get what? The 2 year old post you responded to doesn't mention getting anything.
