Smartphones - Low Battery Mode?

Just woken up this morning, and my battery's only on 2 bars... which isn't a problem in itself, but it made me think of an idea lol
Wouldn't it be good if the phone could have an option to automatically switch to a 'Low Battery Mode' which would shut down all the fancy, battery intensive settings - bluetooth, fancy wallpapers & screensavers, active desktop, camera (or the camera switching on if the slide opens - the user must go to camera in the menu to activate
I'm sure there's a lot more that could be done with that, but I thought I'd throw it open for discussion here and see what people think... I'm sure it would be a valuable tool for people that just want their phone to last longer until they can get home to charge it.
Obviously if Nokia decide to use my idea after seeing this post, I'd love to take the credit for it :-p

Xperia Z3 always awake sometimes, even with Stamina, Ultra Stamina, Low Battery modes

Hi to all,
Has anyone every noticed his/her Z3 always awake (and thus bad battery life), even from within Ultra Stamina mode with no running apps?
This happened to me twice now with just over two weeks of using this phone. I haven't been able to take specific steps to replicate this yet, but 2 days in about 16 days means so far over 12% of the days.
Usually, the phone lasts over 24 hours with moderate use. I normally have stamina mode "on", and set to activate at 50% battery level, and then Low Battery mode to activate at 20%. Note also that all the apps I am using have been installed from the first day I've been using the phone. That is, I have not installed any new apps before I noticed this happening, and when I have "normal" battery life it is using the same set of apps.
Here is an outline of what happens:
I notice a much faster than usual power drain, despite being a typical day of usage (i.e. nothing out of the ordinary).
I go to battery usage, and see the history details, and see that "Awake" has been on constantly, including during long screen off times, and all the while with Stamina mode enabled and active.
I then restart the phone. Problem still there, still constantly awake despite screen off and stamina.
Battery dips below 20% and Low Battery mode activates.
Phone keeps on being constantly "awake", despite no usage and now both low battery AND stamina modes on.
Restart the phone. Same problem.
I turn on Ultra Stamina mode. (I did this last time at 17%)
Phone continues to be always awake. Battery quickly drains down to 5% within less than an hour and almost no use, even though Ultra Stamina is supposed to stretch the life for an order of magnitude longer than that.
I shut off the phone to avoid complete discharge. When I return home, I plug it in and wait for a decent charge before turning the phone back on.
After full charge, I take the phone off the charger.
Phone now works normally again, without always being "awake".
I can't figure out what causes this sequence of events to kick off in the first place. I'm trying to play around with things to get it to start doing this, but so far I haven't been successful in deliberately replicating the problem.
Anyone else experience anything like this before?
My android version is 5.0.2, v. 23.1.A.0.726.

Very Low Battery / Resetting issue - lets make Apple fix this!!!

There appears to be a lot of posts within the last few weeks about the "Please wait, very low battery" message and constant resets EVEN ON A FULL BATTERY. I too have begun to experience this problem. I can only think that there is some kind of bug that has been introduced with the latest firmware and itunes combo. Can anyone that it experiencing this issue, PLEASE put your experiences in a reply to this thread. As an addition to my post below, I have also heard that using the prior version to the latest Itunes in conjunction with the latest may also be the root of this problem. I have been using two itunes, the latest at home and a slightly older one at work. Can anyone shed anymore light on this possibility?
This is from a reply post I made earlier tonight:
I noticed my ipod 5th gen 60 gig was strangely in the red on battery life, so I connected it to my macbook pro and answered a few emails. I then noticed out of the corner of my eye that the ipod resetting. Weird! I had never seen it do this while attached to the computer. So, I went back into itunes and it said something about not disconnecting the device physically - some how the pod had reset and disconnected itself. So, I re-attached it, and moments later, it reset again. Instead of attaching to the computer, I attached the pod to a wall powered usb charger (non-official). After a few minutes, the pod said it was fully charged (weird), so I disconnected it. I thought I should check to see if it was playing music ok and started playing a song. It seemed ok, so I skimmed through a few tracks. Soon the ipod reset itself and started to continuously reset as if in a loop. After several reset attempts (menu and select) I was presented with a "Please wait, very low battery" message screen...
Hmmmm. I thought I should attach it to the wall charger and leave it to re-charge, thinking that the battery must be just plain out of juice. I got past the very low battery message and into the menu with a reset. Strangely, the battery showed as being fully charged... Disconnecting the pod and playing several songs again, the unit reset and showed the low battery message... Leaving the pod attached to the wall charger, even though it said it was fully charged, didn't remedy the problem. More resets when playing a song or two.
Initially I thought that it was a faulty battery. But, before I jumped to conclusions, I googled the above message. This showed me that this is a reasonably common issue with several possible causes. Some of the suggestions to remedy the issue included:
* Reset the ipod - nope, same problem
* Restore the ipod - did this first up... No go
* Put the unit into disk mode attach and restore - nope
* Drain the battery completely and then re-charge on wall charger - nope
* Open the unit, disconnect the battery, and re-attach - I really thought this would work, but nope.
* Disconnect unit, insert wall powered usb, start unit to reset it - nope
* Buy a new battery - NOPE, same thing keeps happening even with a FRESH battery!!!
* Put the unit into diagnostic mode and then charge... This kind of worked in the fact that it actually charged the new battery...
It appears to me that the battery status is all out of whack. The OS seems to think that the battery is completely full, and hence, doesn't take a charge. Equally, even though it says there is a full charge, after the unit plays one or two tracks (requiring a few harddrive seeks I suppose) it will exclaim that there is no battery remaining, reset loop and eventually enter "very low battery" mode. It does the latter even if the battery is new and appears to have been charged (via the diag screen).
So, where to from here... Well not entirely sure, but I reckon that what I have to do is drain the fully charged battery WHILE the unit is active. Perhaps then, it will re-calibrate its internal battery meter... Right now, I have been able to put the pod into disk mode and it is actually showing a battery icon WITHOUT the fully charged symbol (the little plug icon). It also shows a slight depletion in battery remaining. My hope is that this depletion will get bigger over the next few days and, if it does, it may right the funny loop-like state it is in.
Has anyone got ANY other ideas as to how to fix this problem. As a side note, I updated the pod to firmware 1.3 recently. I am considering a restore using an older firmware. Where can I track down 1.2? Can I press the option key and click restore to choose an alternative restore image from the 1.3 already in itunes?
Any suggestions/help is EXTREMELY welcome as I am almost about to give up...

I think my problem actually might be the same ... the other day it was full battery one minute, and the next it was saying "Please connect to power,low battery". I wasn't near a power source, so i just left it. Then it started making this funny whirling sound and the screen went silvery blank, so i figured it was the hard drive crashing. I hooked it up to the computer overnight and the next day I could at least get the apple on the screen to show up and the computer would recognize it somewhat. When it's hooked up to the computer it goes from the apple screen, to please wait, very low battery, to the regular screen with a fully charged battery sign, to the "do not disconnect" screen with the battery charging.. When the "do not disconnect" screen appears, sometimes the computer recognizes it. But when it comes up it first says that an unknown error (-124)has occured and the ipod cannot be synced. And then it says the disk cannot be read or written to. After I press okay again, the screen goes to the apple and back to the please wait very low battery screen... and then in tunes it says the ipod cannot be synced because the required folder cannot be found. Then it comes up again and says iTunes cannot read the contents of the iPod. Go to the Summary tab in iPod preferences and click Restore to restore this iPod to factory settings. Now I would try to do that, but I don't have a summary tab in the preferences, if the preference tab they refer to is under the edit section. For the couple of seconds the my ipod settings appear on the screen, the files on it aren't even the same as before. It says I only have 7.78GB of only songs on my 30GB. Not only do I have more than 7.78 GB of songs normally on my ipod, I have videos and games that also should appear. Everytime it reconnects however, the GB go down? Now its at 6.07GB
It also makes this beeping sound randomly. Sometimes it when the ipod goes into the very low battery screen, but sometimes it beeps during the apple screen, or sometimes during the do not disconnect screen.
The most frustuating thing for me is that about mid-March I sent my iPod away to get a new battery before my warrantee was up. I got it back the first week of April, good turn around period, but instead of getting my old ipod back, I got a refurbished one. Now this is happening to it, and my warantee is already up. I know it can't be the battery that's wrong with it, there may be something wrong with it, but I'm sure they know better than to give me an ipod with a dead ipod.
Now it's coming up as 5.77 GB . . .
When it first happened, I was hoping that I could simply hook it up to the computer and click the restore button. This is impossible however because I can never get to the restore button before the computer unrecognizes my ipod.

My iphone won't switch on. I've tried holding the power and home button more than 30 seconds up to a few minutes but it didn't switch on and went straight to recovery mode. It died of a low battery and i already fully charged it i checked with my itunes.

i really need help here. I have only used my iphone for a month. my iphone won't switch on. it died of a low battery and i've already fully charged it and usually before it even fully charged, it will turn back on right but in my case nothing happened. i've tried holding the power and home button for 30 seconds and up to 2-3 minutes but no logo appear. it went straight to recovery mode. there's nothing wrong with my cable, i checked with itunes and this happened once a week ago but it did switch back on after i tried a few times but now it just won't switch on. i also have problems with my screen as there's some noises to the screen (i hope you get me) and when i turned the camera on, it was as if the whole screen is shaking. i'm currently studying in the middle east and there's no apple store here so i cannot use my warranty. i will only be back home in summer. please help me what should i do to at least switch my iphone on first.

I did a little bit of experimenting. I have an iPad original versions myself. I took it out of the box knowing that I haven used it in months and I expected the battery to be dead and sure enough the battery was as dead as I imagined it would be. For the first 30 minutes I experienced exactly what you are experiencing, but then the iPad suddenly powered up on its own (like it does when plugged into the charger) and I am using it now to type this response to you.
My point is that I am starting tothink that your battery has suddenly died on you for some reason or you have a hardware problem now. I would still try leaving the iPad charge for a while longer - maybe even overnight - and then try again in the morning. Unplug the iPad and try resetting with the home and sleep buttons. Try plugging the iPad in again. Unplug it, try restarting again. Let it charge for a while again.
After trying something like that, if it still will not start up, then I think it's time for a trip to an Apple Store and see what the Apple Techs think.

Kiosk Mode no low battery notification?

I was in Kiosk Mode and got no low battery notification. Just spent 20 min wondering why the hell my computer turned off on me, since I thought I had enough juice.
Am I alone? If not, wth?

The warning is supposed to appear when the battery is down to about 5%.
You could try resetting the NVRAM. But there is no way to test if that solves the problem unless you are willing to run the battery down again.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the third time.
Release the keys.

No sleep mode at low battery - data loss and time reset

I'm having this issue for about a year now:
When I run my macbook pros Battery down, there comes the low battery warning. After a while the system just goes down without suspending anything to my harddisk. When I restart my computer it does a normal start and after logging in I'm experiencing a lot messages due to the reset time. I correct my system-time and restart my mac and the system is back to normal.
Usually I'd say: Replace your CMOS-Battery (I know I have an EFI-Firmware), but where is it?. Or in other words: Is there a "System"-Battery, that would prevent my mac from forgetting the time?
Since I'm not running down my battery to 0 very often I only experience this issue from time to time and never took time to do anything about it.
I would also appreciate a workaround so that my mac immediately starts shutting down, after the low battery warning. That would be great.
iStats battery-Status says: Health:83%, Cycles:333, charge 50%...

Well, the problem, seem's to have reoccured: Battery ran out (even the indicator leds on the side didn't show any life), Time reset to 1.1.2001, again some rebooting and setting the time again...
Is this a sign of a degrading battery health status?
It looks like reseting the SMC didn't help after all.

After trying to down ios 7, iPad will not charge, will not open and will not connect to itunes. The only display I will get is the apple logo, or low battery warning.

After trying to download ios 7, iPad will not charge, will not open and will not connect to itunes. Sometimes, screen will switch from Apple logo to low battery notification, but doesn't look as if battery is charging.

Connect with cable to computer. Your ipad is in recovery mode.

My ipod 60gb classic is showing as fully charged until I connect it to my pc when it comes up with the error message, 'please wait very low battery' and the little wheel goes round and nothing happens, can anyone explain why this is and what i can do?

My ipod 60gb classic is showing as fully charged until I connect it to my pc when it comes up with the error message, 'please wait very low battery' and the little wheel goes round and nothing happens, can anyone explain why this is and what i can do?

I have worked my way through the assistant and nothing works. I have tried connecting in disc mode but although the screen on the ipod is showing that the device is charged and that it is in disc mode as soon as I connect it to the computer it comes up with the error message 'please wait very low battery' and stays like that until I disconnect when it appears to be OK again. I have tried on both pc and mac.
BTW the ipod is an ipod video not classic if that makes any difference.

Is ipod touch low battery life normal?

I just bought my new ipod touch. I found the battery life is quite short. Every day i have to charge it twice. Now I am keeping to use my ipod touch as less as possible to manage charging it once a day. This is really not compared to a regular phone, which you probably can use 3 or 4 days to recharge again.
The so-called dock adapter inside the box is quite tricky! I thought it is the power adapter. Normally when you buy a cellphone, it comes with the power adapter. But for ipod touch, you have to buy power adapter separately! I even don't know what's the use of this 'plastic' dock adapter. i called Apple and asked "You call this plastic piece an adapter!". It's a little funny!
During my first week using my ipod touch, it got stuck or crashed TWICE, two times! One time is when it downloaded an email with a 8Mb attachement.
In addition, I feel quite confusing with so many accounts with Apple, such as Apple store account, iTune account, iChat account, MobileMe account, and even this discussion forum account. Now I have 3 Apple IDs!
The use of MacBook is so far so good.
This is my experience with Apple's products!
Welcome comments and sharing your experience! i just couldn't help keeping myself silent.

Is ipod touch low battery life normal
Yes and no. Even in normal usage, Safari and videos can kill the battery in 4 - 5 hours, whereas music with the screen and WiFi off should last for 22 hours. Most iPT's can last for days in sleep mode, even with WiFi left "ON".
My previous iPod Touch had no battery problems -- the charge would only drop significantly when being used, not while sleeping. Now I have a replacement iPod Touch (the previous one couldn't install the 2.0 Update), and this one won't even last overnight in sleep mode.
Here's what I did in my last test: Turned all the WiFi services off -- Push: OFF, Fetch: OFF, Location Services: OFF, Ask to Join Networks: OFF, WiFi: OFF. Fully recharged the iPT, disconnected it and left it shut down overnight. Booted it up the next day, full battery (Okay so far). Next, I left the iPod Touch in sleep mode for the entire day (8am - 6pm), still full battery (Great!). At 9:00pm, turned on WiFi (and none of the other items mentioned above), used Safari for about 15 minutes, battery went down one notch ~ 90%. (Still normal) Put the iPT into sleep mode, but this time with WiFi left "ON". Woke up the next morning, and the battery plummeted to 10% in about 5 minutes. (NOT GOOD AT ALL).
My previous iPod Touch would have still had 90-80% battery the next morning. And while I would generally suspect the 2.0 Update being the culprit, everyone else I know has been running 2.0 without any problems -- no installation problems, no battery problems. I've been cursed with both issues in two separate iPods.
(I should also mention. I have not yet had a chance to install any media or applications on this iPod Touch, so there's no chance an errant application has somehow triggered a battery drain. This is just a plain iPT with the 2.0 Update and a restore of my Safari bookmarks.)

''Well When i plug in my ipod touch the battery life is low..i let it sit a wyhle.And it starts up to the apple logo and it stay there some time then it restartsback over to the very low battery and repeat(Over&Over)?

''Well When i plug in my ipod touch the battery life is low..i let it sit a wyhle.And it starts up to the apple logo and it stay there some time then it restartsback over to the very low battery and repeat(Over&Over)

Can you reset the device by holding the sleep and home button until the Apple logo comes back again?
If this does not work, try to connect in recovery mode, explained here: iOS: Unable to restore

My ipod is stuck on low battery!!!!! and wont charge

this might be a lil long but please bare with me!
my ipod wont charge. i whiped out my computer last weekend and had to put all my songs back onto my ipod. it was fully charged and worked fine for me.. now my battery is dead and ive plugged it into my computer and right before the ipod died it said i needed to restore it. and i couldnt bc my internet was down. now my ipod battery is dead and i cant charge it.. does anyone kno what to do? and when i plug my ipod in, it shows a battery with a circle on it and under it it says very low battery please wait.. and there is that little flower looking thing and it shows as if it was loading but nothing is happening it wont charge and i cant restore it.. is their any other way to do it??? i charged it mostly on my elbow that i had in my car but i dont have that anymore!! please get back to me, id appreciate it..

I dont know if this can help anybody, but I got the same issue. I sent the iPod to Apple for repair twice, and they sent it back to me saying their was noting wrong with it. I had the time to sync it once, then it got stuck on the Apple logo, and after a while the "very low battery" message showed.
It turn out the I got a playlist in iTunes of more then 65000 song (I dont know how my sons did it...) and it somehow messed the iPod completelly.
To reset it, I force the iPod into diskmode: you reset it using the center-menu buttons combo, then immediatly press the center and play buttons. It turns the iPod into disk mode and then you can restore it in iTunes.
Hope this help

No low battery alarm when on the call. (Nokia 700)

There must be some bug with the low battery alarm on Nokia 700. When the phone is on a long call, it just shuts down without any alarm at all. I had this issue several times. My battery shows that it’s full for about 30% or something. Then I call and have a long conversation. And the phone just dies without any alarm at all. When I try to start it again it seems that battery is drained and I have to charge it to turn it on again.
When the phone is in standby and battery is starting to running low, it beeps and shows a message. However, when I am on the call, nothings is happening, it doesn’t give me a message that battery is low and that it’s time to connect to the charger.
It’s a most important functionality I expect from the mobile phone, to be able to make a call reliably.
It’s a Nokia 700
Software version: 111.030.0609
Software version date: 2011-11-26
Custom version: 111.030.0609.c00.01
Language set: 111.030.0609.05.01
Product code: 059G2D6
Type: RM-670

It seems to me that after I've got version 111.030.0609 installed by Nokia service technician, my Nokia 700 never goes into power saving mode (and it doesn't matter what do I have in Setup / power saving / power saving query). It doesn't turn saving on and it doesn't ask me about it. Something must be wrong with 111.030.0609

My iphone is saying it is charging (has the low battery symbol when i turn t no) but i have waited about 2 hours and it hasnt turned on. what should i do?

i have pulgged my phone in and i've been waiting about two hours now and it hasnt turned on when it is saying it is charging. What should i do? is it broken?

Full Screen: Low battery warnings not shown

When running in complete full screen mode the low battery warnings on my laptop don't show. This makes for some rather surprising screen blank outs as the system goes to sleep (battery conserving mode caused by critical level).
OS=Vista
Task bar set to auto-hide

Desiree, with the stats you've stated, how much battery life have you got left?
From your stats: you charged your phone 1 day ago and you've had 5Hrs, 20Mins usage.
Your usage isn't something I would consider to be excessive and with this sort of usage, you'd ideally expect the phone to have at the very minimum half of it's charge, but ideally about 3/4. I'm of course basing this on the performance of my current phone, which with similar usage as yours and over 2 days, 14 or so hours on standby, still has 1/2 full battery.
I don't want to get too much into the technical stuff, I'm more interested in real world figures and expectation.
With your stated usage above, if you did that everyday, I would and I'm sure you would too, expect at least 3 if not 4 days usage without worrying about the battery running out.
On my old phone, this kind of usage would have killed it in just over a day. Something which I did not find acceptable and was clearly a problem.
I don't want people to start worrying unnecessarily about their battery life if they don't even have a problem. What I'm saying is that with the kind of usage you state, if you still have 1/2 or above battery charge left (with about a day on standby) then I doubt you have anything to worry about. If you can barely get a day and a half out of your phone on this kind if usage then I wouldn't find this normal and you should probably get a 'genius' to have a look at it.
EDIT: I forgot to say: I'm not sure how the Call Time status works. Mine reports the current period as 40 mins and Lifetime as 5Hrs,18mins, but I know I've only made/received no more than 12 mins of calls, since I got this phone
