Battery drain from Bedside mode

Hi, I've encoutnered battery drain before with programs and OS updates. I've done resets, reboots as well as battery reinserts. My device seems to be stable after 10.3.1. I had WiFi, Network and blend, and power saver on at 5% battery. I wasn't using the phone but just used the Blackberry blend software on other ohter devices to check emails. The battery lasted about 4-5 hours before it finally powered off. When i put the phone with the same options but in Beside Mode and did a lock to clear the active use of the display. Apart from Blackberry Blend being off and showing as such in Quicks ettings. The battery drain went down 97% to 74%. By the device manage the battery went down over 2% every hour in a standby mode, where compared to out of Bedside mode with blend on it was 1% an hour. No programs really stand out as causing drain nothing 10% or more since last charge before I put it into Bedside mode. Even normal standby mode with the screen off the battery drain is less. What could be causing this, anyone heard of sometthing similar.

the battery drain in the Night Mode is also happening to my leap device, with all the apps closed, and even Economic Mode activated. i try to figure out what is happening. I will come back if i find the solution. I am also looking for a Battery Saver app. I had a great app on my previous phone, an Android, but I still look for a similar app for BB10.

After IOS 5.0.1 upgrade - Battery drain from 100% down to 78% the following day

I had charged my iphone 4S battery to 100% and my ipad battery to 100% also: both upgrade to 5.0.1, I had plugged it out and I had left it on stand by before I go bed. The following morning I noticed iphone 4S battery down to 78% and my ipad battery down to 99%. Surprised with iPhone 4S battery drain so quickly and where is coming from? I had to re-charged it again thro car charger. Happy with iPad 2 battery.
On iPhone 4S I had turned off all notifications accept Messages, EirText Pro, WhatsApp and Tango . The Location Services is switch to off competely. I have gmail account setting to push to off and manually get the emails. iCloud switch to off.
Is there any advised on the battery issue or is Apple to issue another upgrade 5.0.2 to solved the battery on iPhone 4S?

After two days trying out the problem with my iPhone 4s battery - I had "reset all setting", set up WiFi again and disable all location completely, change the notification list. My Gmail account setting to push to off and manually get the emails. iCloud switch tooff.
I had drain the battery completely until iPhone is dead as requested - I had it off for about ten minutes before re charge fully for overnight. I noticed battery had drain rapidly during day if I use messages and emails.
The next day I had re-charged fully to 100%, then plugged it out and I had left it on stand by before I go bed. The following morning I noticed iphone 4S battery down to 84% the same.
It hadn’t makes any differences or am I missing something…

Battery drains from 10% to 0% very quickly

I think I'm getting fairly normal battery life but I've noticed on several occasions that when my battery reaches 10%, it drains to 0% very quickly. Far more quickly than normal. Anyone else encountered this? Any ideas as to why? I've let it completely drain and then fully recharged it but that didn't seem to help.

This is one of the many, many issues with "7", unfortunately.
It seems that everyone is seeing increased power consumption, (whether they're aware of it or not). I'm guessing (and this is just an educated guess) that the layering and background position sensing and active icons are all adding to the power consumption of each device.
I'm assuming that Apple, in its infinite wisdom, decided to show off all of these exciting new features, so they enabled everything by default. At least, that's what I would do, if I was a marketing type without technical knowledge...
Perhaps there will be a way to turn some or all of the "eye candy" features off in future updates, but that's more of an UNeducated guess!
As to all of the other issues being reported...well, I wouldn't want to be the employees responsible for going through the messages from their feedback pages.
You're not alone, but that doesn't improve our battery life, I'm afraid.

Battery drains from full charge to empty by iteslf

If i charge my mini and dont use it. the battey will discharge itself in a mater of two days. does this mean i need to change the battery or is this some kind of other malfunction, and is this a common problem.

After your mini is charged, how long is it you don't use your iPod?? When iPods are not used for a couple of days they go into something called "deep sleep", iPod's battery does drain a bit even when not in use (I'm not sure why but I use my iPod so much this barely happens to mine). What I do is set my alarm on, it'll turn on the iPod once a day even when I'm not using it and then the iPod turns itself off after no buttons are pressed; just so my iPod won't go into deep sleep

Battery drains from 100% to 99%

When I was charging my iPad it said it was at 100% so I unplugged it and it instantly dropped to 99%.
Can anyone help?

is that 1% every five minutes of use? Did you have it on watching it? or write down the time after 5 minute periods, or average over an hour (fropped 12% in an hour)? Was it in use while this drain was happening?
That still gives 8 hours and 20 minutes if use I beleive. I normally get at least ten hours, but dont do heavy gaming or anything.
A little more information on how you were using it and what the load is? (email being updated as often as possible, do you have dozens of apps that send you notifications? etc...)

My 3GS gets very hot and battery drains from 100% to 0% in less than few hours

The problem is really tricky. I kept tracking the problem, the problem persists only in the following case, if cellular data is on with no dataplan registered.If dataplan is activated the problem disappears

I forgot to add, I closed notification center, all push and pull activities and ping.

Battery going from 70% to 0% in seconds.

I've been having a problem lately with my PowerBook going from a decent battery capacity to zero. Usually I am watching something on YouTube or another video. I've had my battery settings at "Better Energy Savings". I got a new battery during the recall...could it be my battery is on the fritz? My computer is working just fine save for the battery issue.

There have been issues with the recall batteries not lasting a long time. One sign of a lithium battery on it's last legs is when it drops to zero without warning. Typically this happens below 50%, however, as opposed to yours dropping from 70%. You might try contacting either Apple support or your local Apple store to see if they would replace the battery.
You've probably already read how to maintain the battery at http://www.apple.com/batteries/notebooks.html

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

My iphone 3gs battery drains very fast

my iphone 3gs battery drains very fast it won't last for whole day
i just uses mail application and facebook for some time
can u tell why the problem is or need to change battery

I'm having the same problem with my 3Gs. In my case it is not the apps int he background or the brightness, or wifi or email push. The folks at the apple stroe tell me that there is some software glitch that shows up every few months.
I can only get rid of it by restoring my phone as a new device. In which case I lose all of my contacts, settings and all data. VERY frustrating. I had recived two new phones (before applecare ran out) and have done the resotre several times. No one can tell me what is in that creates this probelm. I've tried differenet chargers one by one in case they are the probelm. one int he car, one in a kitchen outlet, one at my home computer (sync) and on at my office computer (non-sync).
Problem just showed up again randomly two days ago, no new apps or hardware. battery drains from full to 0 in two hours.
Apple, please fix.

Why Does My iPhone 3GS with iOS 4.0.1 Cause Rapid Battery Drain

I upgraded my iPhone 3GS to iOS 4.0.1, and now the battery drains very rapidly---needs to be recharged after a few hours---and gets very warm. Before this, iOS 4.0 was fine (although slightly increased battery drain over 3.1.3).
I use Exchange with push and had no issues before iOS 4.0.1. This may be the culprit now because when I turn off "push," the battery drain appears to be normal (although not extensively tested yet). But, I also have MobileMe, Yahoo!, and Google email accounts set up.
Is this a new problem? Anyone else have this problem? How can this be fixed? Anyone have any ideas?

*Reposting this..had done the same thing earlier as well*
This is my observation from past 6 nights;
All 6 nights, charged my iPhone to max and then kept it in sleep/stand by. Not even a single call or mail checked...(11 pm to 6:30 am when my alarm rings)
1st & 2nd Nights, I had flight center, angry birds, twitter, facebook, mail, phone, sms, settings app open in the multi-tasking bar.
Battery drained from 100% to 83%
3rd and 4th nights, i had only twitter, facebook, mail, phone, sms
Battery drained from 100% to 92%
5th and 6th nights, I had nothing open
Battery drained from 100% to 93%
my mail is always in push enable setting to exchange and me account,
location always on, bluetooth always off. 3G off
I thought, the applications on multi tasking bar is actually not draining the battery, but looks like they are...might be a flaw in multi tasking api or may be from developer.
I hope to get an easy way to kill the apps and not let it go to multi tasking bar.

My battery drains from 20% to 0% in seconds
