Iphone 5s battery drain even in airplane mode

Optimize this, optimize that... Just don't use your iPhone.

All this does not make sense.

I did some other kind of test, iPhone knows how much charge is into the battery and how much has been drained from it; iPhone even knows the battery voltage and its temperature! All you need is an application which is able to say how much charge is into the battery, only this can make the comparisons real.

I ran a test using airplane mode with localization service disabled.

I also kept an eye on standby and usage time shown into the battery settings.

Before the test usage time was 1h 48m, stand by was 2h 14m and battery charge was, as reported from the application I used to monitor it, to be at 928mAh.

I left the iPhone alone for 1h.

After this, these are the facts:

Residual charge was 832mAh.

Usage time was 1h 51m and standby 3h 16m.

Conclusions:

Usage time has been increase by 3 minutes, this means that in this hour iPhone left Standby mode 3 minutes only. I can't worry about applications which are using the iPhone preventing it from go in standby, there are none and so it's not a software problem.

Average current absorbed has been between 96±15% ( let's add a 15% error around this value, so minimun current can be 82mA and maximum 110mA )

Using these data I can calculate the expected standby time:

1570mAh ( my battery capacity ) / 96mA ±15% = min 14h, max 19h.

These values are close to real values collected from other test. I.E: Leaving iPhone into standby mode for 7h, battery charge dropped from 39% to 6%; it lost 33%. A full charge (100%) is 3 times 33%, so my iPhone can stay (7h x 3) 21h in stand by.

Drain 33% from battery in just 7 hours doing nothing it's really bad.

Perhaps a such device can stay fine also with 50mA or less. Anyway the problem is hardware.

Apple reports iPhone can stay upto 250 hours in stand by, if so then absorbed current in this state should be only 6.3mA (1570mAh/250h).

Luckly in my case iPhone lasts until the end of my day, so It's not a big issue although I removed Facebook and other social applications.

I really want to know what is the current absorbed in standby mode from an iPhone which is supposed to be in full working order. Can someone do the test and publish the results?

I need battery charge, usage and stand by time before and after the test, which must run with airplane mode and localization service turned off.

Basics from the manual are restart, reset, restore from backup, restore as new.

Don't worry.Its a ios bug.Having the same problem too on my 5s.Try to disable increase contrast and reduce motion for the time being.It might help.

Hi

I have similir problems . I bought iphone 5-s on 25 October . I restored my phone from icloud backup but i noticed that my phone battery is draining so quickly even less than or simi,ir to its predecessor iphone 5 . I restored my phone using itunes and set up it as new iphone but still its not giving me good battery time . I have location services turned off , background app refresh turned off , push notifications turned off , mails using fetch manual . But when i see the usage statistics it shows me 2 hours 31 minutes usage 7 hours 38 minutes standby time 34% usage . Honestly i did 3 to 4 phone calls very short calls , whats app messages BBM messages using BBM app and 5 to 10 min videos on youtube . This seems poor results as what apple says .

😠

Hi all,

I think I also have similar problems. Dropped 5% of battery within 10 mins( only turn on wifi, and used 2 apps). In the same situation, my old iphone4 was much better than i5s. Or it's just normal??!

I Have this problem too! 3 day old 5s. Max 4 hours battery life. Help!

I have the same problem!!! I have a UK 32gb gold model.

My phone is EXTREMLY hot all the time, and my battery last for 3-4 hours on standby!

I have the same problem here. iphone loses 5s in night mode up to 4% in 8 hours! in use every 2-3 min 1%!! go apple .. time to work! 😠

same issue, bought my 5s in Oct. it drains my battery at night even when I am not using it.

went to apple store twice. They said the diagnostic of my battery looks fine, so they won't be able to replace my 5s. They suggested a few things including restore as a new phone, close bluetooth, wifi,... but none of them works. Now I am stuck with the phone with max 2 hr usage. Please help!

I had same issue, i discovered that, Mail app was not connecting and malfunctioning keeping the hot extremely hot on airplane mode and battery draining so so so fast.

After closing Mail app, the phone get back to normal cools off immediately and battery consumption rate is normal again

I have the same problem too. I sent my iPhone 5s in for repair and they said that they replaced the battery, but I'm still having the same issue. I've tried everything, from a restore, to turning off location settings, Siri, iCloud, wherever. Nothing seems to solve it. I've been a long time Apple fan, but This draws the line. I'm selling this piece of shot phone and getting a Nexus 5 or the Galaxy S5 when it releases. **** you Apple. I will never recommend your products again.

I Have this same problem too again😢 7 day old 5s 64gb, Max 4 to 6 hours battery life. if i do battery charge in the moring 100 % then after couple of hour it will be 2% 😟, what is the issue with this iphone 5s , i talk to custemer care they told me to reset , now the same issue again ,and also some issue with navigation if i use the app,iphone5s will be extremely heat it self and battery drain within couple of minutes, pls pls help me ! thanks in advanced😕

No kidding. Just lying on my desk, drained over 20% on air plane mode in 11 hours.
