Curiosity of battery life with WiFi off

Has anyone tried this? I would imagine someone would get a little more than ten hours with wifi off.

Anyone have the patience to use their iPad for 10+ hours without going online? Me neither . Using my MBP to get best battery life, I sometimes turn off BlueTooth and WiFi, and that gives a very small lift - no more than 30-40 minutes so I'd guess, and it is only a WAG, that the difference between using WiFi and BT or not using them both would be perhaps an extra hour on the iPad.

Poor battery life and WiFi connectivity on iPhone 5s

I have bought a new iPhone 5s 16GB running iOS 8.1.2 3 days ago. The device that I have got has a poor battery life and WiFi connectivity. I have tried lots of methods given on the internet like turned off the auto-brightness, reset the phone to default settings.
Then contacted the Apple Care for battery issue. They asked for the diagnostics to check the problem. They said its happening because of the crash of inbuilt app Springboard asked me to try "Set up as new iPhone". Even after doing all these, I am still getting battery not more than 4 hours.
This is not expected from Apple. Such an awful experience on my first iPhone buying.

Where exactly did you buy this new 5S?

Iphone 5 low battery settings with wifi

Are there any special Iphone 5 low battery settings with wifi? Today I was using my iphone and the wifi magically turned off by itself. I figured it was just having trouble finding the wifi so I went to my settings to see what was going on. Somehow it turned itself off. I'm guessing this is because I had a low battery. I just got the battery message saying my phone had reached 20% battery a few minutes before that happened. Has this ever happened to anyone before?

Yes, and you would have had that answer had you bothered to search this forum before posting.
Basics from the manual are restart, reset, restore from backup, restore as new.

IPhone 3gs Battery life with 3.1 firmware

Any news regarding battery life with firmware 3.1???? I have lost at a minimum 25% after upgrading from 3.0.1 to 3.1. Have reset....the device alone and with iTunes....Need help...

I originally posted this in the wrong discussion...
Since upgrading to 3.1, it looks like the biggest battery drain is due to using PUSH with my Exchange email. I can turn off PUSH, use FETCH (even over 30 minute polling intervals) and battery life is close to 24 hours on a charge. Turning on PUSH, but not using it for email (other than my .Mac account (MobileMe), decreases the life by a couple of hours, still well beyond the normal 10 hour work day.
Turning PUSH on for 3 Exchange folders (Inbox and 2 sub folders) results in a drastic reduction in battery life. It can use over 50% charge while on standby... over a 3 hour period. I've managed this to an acceptable (8-12 hours, depending on phone calls) by limiting using Exchange rules to keep most important email to the Inbox and one sub-folder (I may eventually leave all important stuff to the Inbox) and move other stuff into different folders that I can still check on occasion.
Other PUSH activities, using apps like BeejiveIM, AP News, MLB.com, i.TV and even .Mac don't seem to affect the phones battery life too badly.
I'm wondering if Exchange w/PUSH is doing too much, besides listening for new mail and alerting on it. Could the process be simplified to only listen, alert, and mayby increment the count (not downloading headers or message bodies until one actually checks for messages... the iPhone still polls once you open a mail folder anyway).

HT1414 Is iOS 6.0.1 Killing anyone's battery life. No change other than installing iOS 6.1 today...now I cannot get 5 hours of battery life with everything disabled!!!

This isn't an issue. Notice the screen prior to the one that shows usage has an iCloud section and a Manage Storage button. For this button to activate ios needs to download a few kb from icloud. Switching back to this screen forces ios to download those few kb.

Hi All, I've had a movie on my ipad for 2 years that I can watch on a plane, no wifi. Now all of a sudden with the updates recently, it won't play with wifi off. What do I do?

Okay, IGNORE. I realized I was missing an update. I did it just now, to 7.1.1 and it's working now. Weird. hope it stays like this.

What can I do to save my battery life with the new ios 7.3 update

I Loved the ios 7.3 update. My battery lasted for the whole day and I use my phone a lot. I did the ios 7.3 update yesterday and my battery life is horrible. With 2 hours into my day today I was down to 80% battery and I hardly used my phone at all. I love my iphone, but this update was a horrible mistake for Apple!

Thank God that I am not the only one who lost battery life in 7.0.3.
I haven't changed settings from 7.0.0 to now. So I am not going to change settings. With that said my brightness is always at about half or lower, depending on the ambient light. Bluetooth is always off. LTE has always been on since I bought the 5 last year. Wifi stays on, connected or not. So with all these settings as they are, there has been a huge difference in battery life from 7.0.2 to 7.0.3.
I could swear that I went from 100% to 83% charge while I slept for 7 hours. ***??? Really?
I'll test it out again tonight.
I am at work and I turned off LTE for s&g. And still saw 5% drop in 40 minutes with a 2 or 3 minute use.

Battery life sudden drop off!

Hi all i have had my iphone4 for about 3 months with no problems at all! in fact it been great. But i charged it up last night as normal and went out for the day and notice that the battery was going flat very fast?
I was not useing the phone at all as i was busy and only check it for emails ect nothing unnormal.
I went out at 10.30 and it was flat by 4pm and i mean dead!I charged it again and its now been off charge for 2hrs and is at 60% already.
I had a 3gs before this (my wife has it now) and it is still as good as new and thats a year old or more.
Has the battery had it? if so why?
PLEASE HELP LOL
Regards
Andy

I have a similar symptom to the original post, and have tried the reboot suggestions, but they didn't work. I have had the phone for a month or so, replacing a 2G, and initially battery life was about the same. The battery will not last even for a day. When I went to bed last night, the phone had 70% charge and it was completely dead by the morning today.
To diagnose a separate issue (data use increased 5x to 10x on both my phone and my wife's 3G iPhone after changing to the 200MB/mo plan), I started shutting down potential data users: no push, no fetch, no notifications, made sure apps were not running in the background, etc. It doesn't seem to make sense, but I would say that battery life got worse.
My question: is there any utility or available to check or log what's going on in the phone?
Thanks!

Increase battery life with iOS4

Besides for turning off Wifi or push notifications, or shutting down, is there anyway to make the battery life last longer than it does with iOS4?

The answer, I regret to say, can be found in [this thread|http://discussions.apple.com/message.jspa?messageID=11980463#11980463|Th e sad truth about iPod/iPhone battery life].
In order to upgrade this solution from a suggestion by someone who isn't suffering the issue to an account of firsthand experience, I'll tell you that in a household with 2 iPod Touch devices that were both decimated by the upgrade to iOS4, this method cured the battery life of both units and will probably work for you.
+The solution boils down to the following:+
Using iTunes, run the "Restore" to factory settings.
I performed this technological equivalent of ritual sacrifice with full knowledge of the devastation it would wreck on the volumes of settings/passwords/usernames/servernames and countless other bits personal information manually entered over 2 years. I did it partially because I only half-believed it would work and was wantonly hoping for an even greater excuse to complain. 3 days later, I'm still finding information I have to look up and reenter.
+For my own part, I would have greatly preferred the ability to restore my iPod to a state just prior to installation of iOS4.+
Perform this restore at your own risk.
On the 4th page of the thread linked above, +Lawrence Finch+ describes a few less drastic steps you can attempt first if you are equally reticent to give your iPod a lobotomy. I tried them all. A series of acts which served only to prolong the inevitable and increase the amount of time wasted as well as to further inflame my ire.

Battery life with 2.1

I have noticed a greatly decreased battery life since moving to 2.1
Any suggestions?

I have battery draining problems with my iPod touch as well. The funny thing is, though, that it just started. I've been running ver 2.1 since it came out, but only since last week has the battery been draining like this.
Typically, when I get home, I put my iPod with my wallet, keys, etc. The next day when I go to use it to listen to podcasts during my commute, the battery is REALLY drained - sometimes to the point where the iPod has shut itself off. I used to be able to let it sit all weekend and on Monday it would still be charged.
I've just tried turning the wifi off, so we'll see if that helps. However, I've never had to do this before....

Upgrade to OS4.1 causes fast battery drain with WiFi on

I've just upgraded the software on my 3G Pod to 4.1, only to find that it has led to a much quicker battery drain with the WiFi on. Is there a fix for this or can I revert to the previous OS?

Owen Glyndwr wrote:
Thanks llaass, but the discussion that you direct me to does not really address the issue of why a very recent upgrade should make such a significant difference. I had already realised that turning off WiFi makes a difference. Perhaps my question should have been addressed to Apple, since it appears that it is their so called 'upgrade' that has led to a deterioration.
I'm using iOS 4.1 on my iPod Touch 3 gen with no battery drain problem. This suggests that there is another factor at play which must be present to provoke this problem between the iPod and iOS (i.e., a specific App, a router type, or ?).

Battery life with os x 10.8? Dies SO fast?

So I just upgraded to os x 10.8.0 today and when I initially bought my macbook pro, the battery life was kinda already pretty bad. It's a 2009 model that I bought off of ebay and the user said he had replaced the battery 2 months ago (so around April or so). He said that the battery would last 5-6 hours with average use (surfing the web, youtube, facebook, etc.). He completed wiped the hard drive clean before sending me the laptop and when I got it, I installed Snow Leopard and the battery life was CRAP. it lasted me maybe 3.5-4 hours. So i emailed him and he said that he had the most recent operating system before, but he wiped it clean to send to me and included the snow leopard installation discs. So, I searched it on google and everywhere and I still don't know why. I thought that upgrading to 10.8 would help, but it's exactly the same. My laptop is currently on the lowest brightness before it goes completely black, I'm watching a youtube vid, on facebook, and typing this. My battery went from 100% to 86% in 30 minutes. 30 minutes! That's ridiculous! Would upgrading to 10.8.1 or 10.8.2 or even to mountain lion help?? I don't know what to do!!

Hello,
Thanks for your suggestions.
I've resolved this problem.
As i guessed, the cable connection between the samsung lcd monitor and the mac mini was the source of the problem.
I bought a DVI cable, right on replacing the D-Sub cable into new DVI one, it's gone.
I feel lucky because i don't know what was the exact problem but it's fixed.

Horrible battery life with brand new iPod touch 2G

There is definitely something going on with the battery life on my 2G. I just got a 32GB iPod touch 2G on Wednesday to replace my 32GB iPod touch 1G and the battery life is atrocious.
I charged it up fully and Fetch/Location Services is disabled. Backlight was set to auto and WiFi was on. I browsed the net for about an hour (no music playing), watched a 6-minute YouTube video, and played five minutes of X-Plane.
The 20% battery message came up after about an hour and a half of total on time from a fully charged battery. My 1G would have been above 70% at that point.
Then last night with a fully charged battery, I read a few posts on Apple Insider, played some Solitaire, then put the device to sleep, and awoke this morning to find the battery at 20% with a warning message. I always have WiFi on.
Now I am using my 2G no different than my old 1G -- I have the exact same usage patterns including WiFi usage, yet battery life is much, MUCH worse. What's going on?

Fully charge the iPod a few times, then use it until it goes out of battery. Do this 7-8 times, then check the battery life again - new batteries do this often in the beginning.

Lumia 1020 battery life with here+

My Lumia 1020 battery life is very poor when using here+ for navigation. The phone also gets hot. Typically it only can be used for about two hours.
Even when connected to the car cigarette lighter outlet the battery consumption is faster than charging and the phone gets hot.
Is this normal or should I send it for service? The phone is about 4 months old and in normal use the battery life is more than one day and I have not noticed any heating either. I have installed all available updates regularly. I have also installed the maps I normally use into the phone.

Thanks,
I understand TomTom is not a phone and has less fuctions than Lumia. For this reason its power consumption should also be lower. I believe though, that a phone maker like Nokia has put a lot more efforts to reduce and optimise power consumption.
I have now been testing with a 3.1 A charger in the car and it is able to charge the battery while navigating. The device does get hot, however, but as you say it is normal.
I did also try to use it when biking and was using a 10 Ah Powerbank with 2 A outlet. That did not seem to be able to overcome phone's power consumption, but the battery was slowly reducing charge. This arrangement would anyway allow several hours navigating, which is quite enough for normal use. Without this external battery its useless for longer biking or walking tours, unless you turn off navigation when it is not necessary. This is a bit complicated, though. TomTom is even worse for this kind of off-line use, its battery seems to be quite small.
I also noticed that it is important to remember to turn off navigation when keeping the phone in pocket, it really gets uncomfortably hot there.
I'll also have to study Lumia's manual a bit more carefully, as I had often difficulties in changing targets and turning off navigation. Probably just because I had misunderstood some instructions.

13' MBP: horrible battery life with Lion

I upgraded to Lion a month or so ago. I really like the functionality of it and it's features, but my battery life has gotten horrendous! I've done everything I can find to try to fix it. I've reset the SMC, reset the PRAM and NVRAM and even installed the gfxCardStatus app (which said my card wasn't compatible with it) and nothing has worked. If it helps, I have the baseline 2010 MBP with 2.4 GHz Intel Core 2 Duo processor, 4GB 1067 MHz DDR3 RAM, and NVIDIA GeForce 320M 256MB graphics card.
At 50% it just told me I have an hour left when I used to have 3 or more! Is there anything I can do to fix this?

In addition to the suggestions in
http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh21207.html
be sure that your System Preferences > Time Machine is set to "OFF."
When ON but not connected to an external disk andexternal power adapter,
Lion's TM writes backups to your startup disk. This, and any other avoidable hard disk use, will reduce available battery time.
(BTW, per http://support.apple.com/kb/HT1490,
portables with built-in batteries do NOT require calibration)
