Does keeping mobile phone switched off for a certain period of the day help conserve phone’s battery?

    Cell phones constantly use power to "Call Home" to the nearest cell tower to say where they are. They don't do this when they are OFF.
    We live in a rural area with minimal cell reception, and the need for the cell phone to go to full power (when it's ON) for this internal communication, drains the battery. (It's just sitting there in ON - we're not talking, or calling, or receiving a call). So, we keep the phone OFF when it's at home (preserving the battery charge); and only turn it ON when we're in town (with it's lots of cell towers).
    The battery power consumed in populated areas, when it's ON but dark may be minimal - but in rural areas, it sucks the battery dry to be left ON - even if there's a dark screen.

    Yes. Phones use battery power all the time, and even in standby mode they use power, so switching a phone off should stop the drain. In the olden days ("brick phones") the manufacturer would quote "standby time" and "talk time". This is more difficult to do with smart phone since "standby" is not as well defined (Wifi switched on or off? Bluetooth? Apps running in the background?) but the principle still applies. On the typical smart phone, you'll be lucky to get more than 2 or 3 days of standby, but if you switch it off then it won't be draining the battery at all (or almost at all, batteties are not perfect, and neither are phones, there's always a small amount of residual leakage).

      Thanks. If battery is used for clock , alarm even when phone is switched off , how would removing battery for some time or keeping phone with battery switched off make a difference?

    Mobile uses batteries power even if it is switched off. The background application still working after switching the mobile off such as alarm. But of course it helps in conserving a large amount of energy.

      Thanks. Please tell do you mean , helps conserving battery hardware resources?

    Turning any battery operated device off would help conserve energy and life, but heat or extreme cold may result in lowered battery life as well. Any battery usage with the phone turned off would be very minimal and you should not see any noticeable difference in remaining battery life. If you do, either the battery is beyond its lifespan or is damaged and should be replaced.

      You are right Dalsan! Two thumbs up for you.

    Charge the battery fully. Take it out of the phone. After 24h put it back in the phone and check how charge is left. If the battery full then its okay then your phones is consuming power from the battery while supposedly off. If the battery percentage is low then the battery may be wearing out and require replacing

      it should help, unless there is hardware problem

      You mentioned -- quote " If the battery percentage is low then the battery may be wearing out and require replacing" -- unquote. Please tell , are there apps which can monitor and notify if the phone battery is wearing out and requires replacement ( instead of manually removing and replacing batteries ).

    Obviously No !
    The phone uses a very neglegible amount of battery power for Time and Date !
    If the battery goes to Nil, even the date and time becomes incorrect !
