I Dont Want A Soft Reset

Why do you want to do a hard reset but not a soft one?

There terms are vague, but "soft reset" basically means a forced restart. Usually just press the power button down until the phone restarts (may be 10 seconds or more - ignore any prompts on the screen). If you have a removable battery just pull the battery out instead - if you can do that then keep it out for a minute or two while you are there (ensure everything is discharged). Though in most cases just restarting the device will do as well.

A hard reset I understand to be a factory reset, i.e. erase all user-installed apps and all user data (does nothing to the system software). That's the thing you'd want to avoid if you can.

The best solution however is to identify what is causing the power drain and deal with that. The system settings can tell you something about power usage, apps like GSam Battery Monitor can give you more details. If the cause is a rogue app holding the phone awake you want to know which one.

Of course if you are living on the edge of network coverage, constantly losing signal, searching and reconnecting (or dropping from 4g to 3g then switching back) that's going to drain you quickly no matter what you do (apart from changing network).

maybe you are looking at the wrong app. there is a possibility that another one is draining the phone. it is hard to say. have you tried just rebooting?

 

When checking Settings >> Battery you've mentioned it states the battery is at 100% after charging but it might be more revealing as to which app is draining your battery overnight to instead check your Settings >> Battery menu in the morning when the battery is depleted to see which app, or apps, might be the possible source of a problem.

 

Exactly: the battery menu will tell you what has used power in this charge cycle. So you need to let it run fairly low and then look at it.

If that isn't enough then try a better battery monitor app.
