Batery Drain and poor reception question

[brn2rnjk1]

I charged my phone up and left it unplugged with wifi on through the night last night. Woke up and 100% battery.

In the office today (no internet) where we have very bad reception that comes in and goes out and within 5 hours or so lost over 10% (no usage, in my jacket pocket whole time).

So, is it right that if the phone is constantly searching and unsearching to cell signal, it will drain quickly.

Thanks.

Yes that can happen if your phone is constantly trying to lock onto a tower and failing.
