IPhone :: 4s - New - Battery Drain And App Crashing

Jul 4, 2012

I have recently bought a new iphone 4s- 16gb. Updated it to 5.1.1 version.

The iphone has major battery issues. I charged one night and morning it was drained. It was only on wifi.

Also, while on wifi - the battery drain is too much. The standby time and the usage time are generally same.

- Location was off
-Bluetooth off
- wifi on
- Emails on

The drain is very fast. Next - the apps like facebook, contacts, watsapp etc carshes quite frequently.

I installed an app called 'Battery Doctor', in the stats i found that the CPU usage is very high even wiht only 1 app running. similar is the case for RAM usage.

Info:
iPhone 4S, iOS 5.1.1

IPhone :: 4 Battery / How Much Does Wi-Fi Drain?

Jul 28, 2010

Previous smart phones I owned turned wifi off when the screen went dead. So essentially wifi didn't really drain any battery and wifi was easier on the battery then 3g when actively pulling down data.

So now I am on a 2gb plan (previously on unlimited) and sensitive to this I keep my wifi on all the times to use my home connection when possible.My battery however is barely getting through a full day. My wife was getting solid days but she had wifi off.Do you think that this is effecting it? I use my phone quite a bit throughout the day.

IPhone :: 3GS And Battery Drain

Aug 18, 2010

I bought a 3GS running 3.1.3 from a friend of mine. Brought it home, used jailbreakme.com to jailbreak it and Cydia. Worked fine, put my Tmobile SIM in, made calls, downloaded apps, ect. Plugged it in overnight, got up this morning and took it off the charger at 100%. Leave it sitting and 5hrs later the battery is down to 30%! Wifi, 3g, push, ect ect are all off. Someone please help, I was so excited to get this working and now the battery doesn't even last half a day with no use!

IPhone :: 4s - Battery Drain With 5.1.1 OS

May 24, 2012

My iPhone 4S had been working great, but after upgrading to 5.1.1 OS it is draining the battery by the afternoon every day without any or very little use. I rely on my phone for business and it can't even make it through a work day! It is draining about 4 times faster than normal. I found a post referencing to 'Reset All Settings' which I tried yesterday, but it still is draining fast. I tried resetting, rebooting, shutting down all apps, but nothing helps.

Google Nexus 5 :: Battery Monitor Do Not Add Up To Total Battery Drain?

Nov 29, 2015

Nexus 5, 16GB, MRA58N (stock, not rooted). Sometimes the power percentages shown for each process in the battery monitor do not add up to the total battery drain? I am finding that sometimes they add up to within 1% of the total shown.... and sometimes they are WAY off with as much as 30% of the displayed battery drain unaccounted for. Since I don''t have access to the battery terminals, I can't determine independently whether the percentages shown are simply inaccurate, or whether there are missing processes (ie., processes not shown at all in the battery monitor).

IPhone :: IP4 Battery Drain / While Plugged In?

Sep 6, 2010

I plugged in my ip4 last night a couple hours before going to bed, and noticed that it was up to 100% when I went to bed. I woke up and, still plugged in, was at 97%...?Is this normal by any means? I mean, I know my MBP which I always have plugged in will drop charge while plugged in to such %'s (97,98,99).however my ip4 has never done this before.

I used the phone for calling, sms, web, mail and music, NO GAMESail has no push notification.Yesterday I've disabled all notification and some other things to see if the battery could be better, tried to not recover the old back-up

IPhone :: 4 IOS 5.1.1 Battery Drain Partially?

May 14, 2012

A week ago I realised that my phone was heating up rapidly and my battery was being drained alarmingly fast before days end. I used to go a whole day and would only hit 50% battery use. After some research, reading and testing of my own, I can say with some certainty that after turning off the push notification and location services on my phone battery life has dramatically improved returning to pre update performance and the overheating has ceased.

IPhone :: IOS 5.1 Seems To Drain Battery Faster Than Previously?

Mar 18, 2012

Upgraded to iOS 5.1 a couple weeks ago and since then battery drain has been horendous. Have problems on my iPad 1, have problems on my iPhone 4S, but iPhone 4 seems not to be affected as badly. I have disabled options and disabled apps (though they should be paused and not draining the battery) to no avail. Disappointed and think I'll go back to my iPhone 4.

IPhone :: What Is The Affect Of Siri On Battery Drain

May 3, 2012

I'm not here to report a problem. I'm just asking, out of curiousity. Yes, I've seen all the threads, and read the obligatory items on optimizing settings for power saving. Heck, I'm a "battery miser". I have no problem with premature battery drain. In fact, I'm a "light" user of my iPhone 4s, and have no problem getting an unusually long time out of a charge! Perfectly satisfactory.

However, I do *not* have Siri turned on (fear of battery impact). I was thinking of "toying with" Siri. But I haven't found, anywhere, a discussion of the affect of Siri on battery drain. Before I bother with an experiment, may I find, read, and benefit from the experiences of others in such a pursuit? Does Siri exact a heavy toll on the iPhone battery?

IPhone :: IOS 5.1.1 Upgrade: Hot While Usage And Battery Drain

May 18, 2012

Since iOS 5.0.1 I never had. Artery problem. But after recent upgrade to 5.1.1 I found that while using usual apps, including very simple like card game, my iPhone became very, uncomfortable hot near sim slot location. I was tried to reinstall sim card several times - no effect. Battery drain now terrible in active mode, about 1 percent per one or couple of minutes.

IPhone :: Wifi Drain On 4s Battery Is Unacceptable

Jun 29, 2012

My iPhone 4s is my first iPhone, and I really enjoy using it, but I was severely dissapointed when I discovered this major battery-usage flaw. Using wifi drains the battery incredibly fast. If wifi is left on, it will drain the battery (just on standby) within a day. Once I switched off wifi, it lasted over 5 days on standby. Do they know why wifi drains the battery like this, even when just on standby? Can this be corrected? I figured they would have fixed something like this by now if they could; I'm concerned it is a hardware problem that can't be addressed.

IPhone 5 :: IOS 7.1 / Battery Drain Random Shut Down

Jul 1, 2014

I have an iPhone 5 running iOS 7.1. Today I left the house at 8:30 am with 100% battery. I had a breakfast meeting and put my phone on the table while we ate and did not use it. By 10:00 my battery was down to 3%. On other occasions, the phone shuts itself down while there's still 30% power, and I have to plug the phone into a charger to get it to restart. When it restarts, it shows >30% battery. I've been struggling with both issues for months (as have numerous friends with iPhone 4, 5 and 5s). I do not believe it is a hardware issue, but rather, an issue with iOS 7, which is when the problems began for me. My old iPhone 4 running iOS 6 would go an entire day of heavy use on a single charge (and usually had juice to spare). There is a serious power management problem with iOS 7 and I'm deeply disappointed that Apple hasn't addressed it. Â

You can conserve battery life by switching off cellular data, closing apps every time you finish using them, and other tricks mentioned by users here, but then the phone doesn't function as advertised and is no longer a smart phone. It is unreliable and essentially useless as a business device. iPhone is advertised has having 10 hours talk time and 10 hours cellular data. It doesn't even come close. I encourage everyone to contact Apple directly to address this problem. Something tells me Steve Jobs never would have let this happen.Â

Safari Causing Battery Drain On IPhone 5s With IOS 8.1.1

Dec 3, 2014

I have done the reset and the restore to factory settings and manually reinstalled my apps. The battery continues to drain. It will not last a day without recharging. Usage shows Safari is taking up the most of the battery usage. Safari is not open, yet it takes up most of the battery. This is both before and after the restore to factory settings. I did not restore from back up in case the back up was corrupted.

FYI- I have an iPod Touch which is doing the same thing. I took it to the Genius Bar and it was replaced due to a firmware issue. The replacement is now demonstrating the same issues. Restoring to factory settings and manually reinstalling all of the apps worked for a while, but it has now reverted to the same behavior. It had none of these problems prior to the update to iOS 8.
