iPhone 4/4S Users: How much battery do you lose overnight?

[SimonTheSoundMa]

iOS 5.0.1, I would be down to 40-60% charge. I have tried 5.1 for two nights (8 hours sleep) and they were 91% and 93%.

I have even gone to switching some of the location based services back, and also Siri raise to ear.

I recharge it overnight and don't understand why some people don't.

iPhone 4S
IOS: 5.0
Battery Loss: 1%. Jailbroken, WiFi enabled, push for email, notifications enabled, alarm clock enabled, not plugged in, and 1 playlist going (roughly 13 songs).

Do you have an iCloud email address? Exchange? Do you have mobile data enabled? What about VOIP apps like Skype / Viber running in the background? What about iTunes Match?

I dont generally see anymore than a few percent. Maybe 2-4%? iPhone 4 5.1. Everything except bluetooth and fetch turned on

iCloud, yes.
Exchange: no. no Exchange server for me to use, nor would I want to!
Mobile data: yes.
No VOIP apps running. However, I have had other apps still running in the background (Banks, HuffPo, LiveATC.. I try to keep those to a minimum).
No iTunes Match running, either (haven't really had the time to sit down and play with it).

I think the key for me was that I waited roughly 3 months after the iPhone 4S was released before getting it, so I think I avoided a lot of the battery problems that the early adopters had. It gave Apple time to figure out what was going on, plus to replenish their stock.

I never paid attention to this since I don't really have a problem with the battery life, but apparently I lost 16% in 7 hours. Still on 5.0.1..

Considering I leave mine plugged in overnight, none.

iPhone 4
iOS 4.3

Losing 5-45% with Skype backgrounded, notifications on, 3G on, Fetch off, bluetooth off, wifi off, 3-4 at&t "bars."

Unless you use your device as an alarm clock I'd suggest always charging powered off.

Why? Just curious.

 

[RotaryP7]

The hell? Why don't you people leave it charging overnight? I do. I don't have battery issues. I don't have to charge ever again until I go to bed again.

And I use my iPhone a lot. I also have everything turned on except BT.

 

[barredfreak]

iPhone 4S
iOS 5.1

I lose 1-2% overnight, with mail set to Manual.

But, normally, I leave my phone charging overnight. I figure that's the optimal way to get the best battery usage from a day. It's like a cycle, come to think about it.

 

[pgleesonuk]

If my iPhone has WiFi on, then I loose 20%
If WiFi is off, only a few %

The usage time goes up dramtically with WiFi on. Not just the battery drain.

For example
WiFi on : 6 hours standby : 2 hours usage
WiFi off : 9 hours standby : 10 mins usage

What is my iPhone doing when the WiFi is on?

iCloud back is off

 

[sparky1499]

I removed the shoddy Facebook app.

I dropped just 3%. Go figure...

 

[MistahMumford]

Why? Just curious.

Sorry for the late response.

Coming from Android battery preservation was of the utmost importance. Due to this, I've done a fair amount of reading on BatteryUniversity.com and charging powered off gives a full charge without things background syncing and "fooling" the charge process.

 

[Lilzoe5]

I lose about 1-2% with wifi on.....to save some battery reset all network settings and turn off raise to speak with Siri. That will definitely save you some juice.

 

[Menel]

I have the opposite, I gain lots of % points and wake up with 100%.

 

[Hastings101]

I always charge my phone up at night but the few times I didn't have a charger with me it fell anywhere from 5 to 10% (on 5.1)

 

[MimiHome]

This is good to know if you are interested in the specifics. I normally plug my phone in overnight, or turn it off which will save the battery life.

 

[nw9]

I lose about only 1% overnight on my iPhone 4 running iOS 5.1.1. It's been this way since I got the phone. Because I have the low data plan I turn off data when I'm not using it and I always have my Wi-Fi off unless I need it also so no power draining wireless connection is on when I'm asleep. I have noticed my battery drains quicker when I leave my 3G data connection on even when I'm not using it.

Another thing I do is calibrate my battery by fully depleting it and then fully recharge it uninterruptedly when I notice it starts to drain too quickly. I do this about once every 2 months.

 

[patelronak5]

iPhone 4S
iOS 5.0.1

about 3-4%...

 

[spillproof]

iPhone 4, 5.0.1.
I always charge while I'm sleeping. But if I forget, it might drop 1%.

3G, 5 alarms, a few reminders (time remind only), no wifi, manual mail, no diagnostic & usage data, no "system services" in location services, no push notifications, no iCloud over 3G.

 

[bp1000]

Forgot to put my phone in airplane mode last night and was surprised to see it only used 2% overnight.

However I've turned 3G off as I'm at home for a few days where I have wifi coverage.

On 3G I normally loose around 8-10% so I normally put it in airplane mode.

Seems EDGE is just as good which really baffled me this morning seeing 98% left on the phone. Only a few emails came in during the night.

 

[danetello]

Normally lose about 5-10% with email (around 8 accounts) checking every 15 mins, and on silent.

 

[llfloyd79]

I went to bed last night around 11pm and phone was at 100% battery life. Woke up this morning at 4:30am and battery was still at 100%. That's with email pulling every 15 minutes and wifi on, had the NBA Game Time app sending me notifications about the game and bluetooth off.

It's 4:55 now and phone finally went down to 99%.

 

[pgleesonuk]

do you have an iCloud account on your phone?
If so, which items do you have selected

Thanks
