How long would a smart phone charge last, with no use?

[Zak33]

Hello people

I have, in my top drawer at HEXUS towers, an Acer Liquid Z630.

I updated it on wifi, charged it fully and then left it , screen off, but still on wifi.

It has NO sim card so has no network coverage
It has no apps except the default stuff, and becaue it's NOT signed into a Google account, I don't think it's doing much.

Question : how long will it last before it goes flat? It's only use is me checking it by activating the screen daily

Have a guess - :-)

28 days, 5 hours and 3 minutes.

16 days 10 hours.

If there is no heating at night, I'd go for 10days.

4 days, 7 hours.

Specs reckon 1030 hours, which I scoffed at until I got to the battery size ... 4000mAh! That's huge! My KEYone only has 3505 mAh and that has lasted over 3 days with light usage and full mobile connection before.

Now, I'm sceptical it's going to manage the 42+ days the specs reckon it could, but I suspect it'll go for .... oooh, let's say ... 6 days 10 hours.

My Moto E 2nd Gen has a 2390mAh battery and lasts 12 days easily on standby (network connection only). So I would guess yours would be 24 days if it isn't connected to the network.

First few answers very optimistic imo. I'm going with 4-5 days. The answer may change if you can turn it onto airplane mode, don't know about their OS but you can then turn on wifi, reason being that it may search for signal even without a sim card? In which case it will burn through battery faster than if it had a sim and signal. With a big battery as described maybe 10 days if that's not the case though?

Died this am (4th April just after 10am)

So just over 12 days

I've very impressed I have to say. It's hardly a clean Android install and has loads of tat pre installed.

Should I repeat it, but with Wifi off?

I'd be interested if you ran the test with WiFi off, but a SIM in and the phone set to 2G with no data. See if you can match the 'old days' when you can go at least a week between charges on a phone with a black and white screen.

I second this

If I can do it with a battery nearly half the size, it shouldn't be a problem.
