IOS 4.1 on 3G - Battery Meter Wrong

Has anyone had problems with the battery meter after updating to 4.1? The meter is correct while discharging, but not while charging. To get an accurate reading after a charge, the only solution I've found is rebooting the phone. I've tried several times with the same result. Also, I've tried draining to see if recalibration was needed or something. Any help would be appreciated.

Greetings,
There is likely no issue with your phone/software, other than you may need to calibrate the meter. That old phone can have a meter go out of calibration with the installation of iOS 4.1, especially if you are going straight from 3.13.
All you have to do is to charge it up overnight, then run it down all the way until it shuts itself all the way off, not just go to sleep. After that let it rest a half hour or so, and fully charge it, without using it. It's best to plug it in, and then do a full shut down, and let it charge fully. The meter should be in calibration, after that.
I've seen some folks have to do this a couple of times, if they continually short charge it, but once is usually enough.
I wouldn't pay too much attention to what the meter says while it's charging, as other things are going on that will make the meter fluctuate a bit, since it's on.
Cheers,
M.

Battery meter after iOS 4.1 upgrade

Hi
Kudos to apple for finally sorting out the slowness issue with the release of iOS 4.1. I have noticed one problem though. My battery meter is constantly showing the phone as having a full battery. I have had my phone on all day today. It's now 1am and the battery hasn't dropped one bit. I've been playing mega jump for a good few hours today (still can't get past level 1 lol) and no drop at all.
Have apple created a super battery or do we have a bug?
TIA
Mark

I am having the same problem too. Its my first occurence, where to battery meter constantly shows its fully charged, and it remains just there.
Do you have any solution to this?

Battery Meter completely wrong

I am using a first gen Touch with OS 3.1.3.
My battery meter never shows the correct amount of charge - it always stays somewhere between fully charged and about 3/4 charged.
From there it will unpredictably immediately jump down to red and give a "battery depleted" message. It will shut off a few minutes later. When I plug the iPod in, the meter immediately displays a full charge again and says fully charged.
This has been happening a few weeks now. I recently restored the iPod and I still have the same problem.
I am wondering if there is any way that I can recalibrate the battery meter - I considered paying for a new battery, but I still get a good amount of life out of it and so I don't know if that is necessarily the problem.

I would start by doing the standard three fixes for iPod touches - Restart, Reset, Restore. Anyone of the three may take care of your problem so check it after each one.
Restart - Hold the Sleep/Wake button down until you see the red slider and turn the touch off.
Reset - Hold the Sleep/Wake and the Home buttons down together until you see the Apple logo. This will take about 10 seconds.
Restore - Plug your touch into iTunes and follow the instructions

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 ..........

How can I recalibrate or reconfigure my Treo Pro's battery meter ?

Hello ! I've got a problem with my Treo Pro and I'd like to get more information about the solution.
I've bought a new extended battery (2400mAh). It works very well, but my phone's battery meter doesn't give me correct datas about charging level of the extended battery. I've heard about the same problem on other forums from other people who use extended batteries. Independent on the manufacturers, they have the same problem with their Treo Pros. Please, help me. We have to use extended batteries, because the Palm's original battery (I think it is a 1500mAh) isn't fit to anything (my 1 month old phone works with its original new battery for a 3 days). My phone works very well with the extended battery for about 6 days. During this period in the first 3 days the battery meter runs from 100% to 0%, remain on 0% in the next 3-4 days until it depleptes and it annoy me with its messages (please charge the battery avoid losing datas and so on).
So I'm searching for any registry hack, recalibrate phisical methods, idea or any other way to reconfigure the battery bar. Please, help me or give me more information about the developer's e-mail or developer's forum.I'd like to solve this problem.
Thank you for your help.

Clamshell - battery meter problem?

Somebody has to be able to explain this one to me...
I bought a used graphite 466 to hold me over until I can save up for a brand new laptop. It was running like a dream, at least until...
I turned it on one morning, as I usually do... and the battery meter was acting really weird... I still got my 4 hours of use out of it, but the meter very slowly ticked down to about 95%, then took a huge nosedive down to just 5% in an instant... I was forced to run off the adapter until my class was finished, and I brought it home...
I was at home, adapter hooked up so I could recharge it while I continued using it. The charge slowly crept up to maybe 9 or 10%, then jumped straight to fully charged. That was the point where I realized something was very wrong... so I scoured the support pages, and the discussions, to try to find something that matched what was happening with mine.
I did the PMU button, reset the NVRAM through open firmware... I even let the battery run down fully and took it out of the laptop for the night...but there was no change...
Next, I decided to download one of those programs to check the battery... and either I'm very confused, or the numbers just dont add up.
According to XBattery, my battery stats right now (fully charged and running off the adapter) are:
installed: yes
charging: no
charger: yes
battery %: 100
(so far, all makes sense... what a fully charged battery should say, I would think... but then it gets weird)
Max. cap: 3.600Ah
Curr. cap: 64.860Ah
Charge: 64.860Ah
(this part makes me think maybe the labels for these numbers are mixed up somehow... how could my current capacity be that far above the max?)
voltage: 16.858v (the adapter itself says it should be 18v, but this is close enough)
amperage: 0 (it's not currently drawing any power from the battery... i guess?)
cycles: 80 (charge cycles, I guess...sounds way too low for it to be a battery problem... )
Flags: 2d000005 (no clue... I'm sure they mean something, but I don't know what...)
Now, I'm no expert as to what all those numbers really mean, but my impression is that it's not a battery problem per se....
Anybody have any idea what's wrong with my machine? Is there something simple that I'm missing here?

I ran a terminal command to show my battery information:
"IOBatteryInfo" = ({"Capacity"=64860,"Amperage"=0,"Cycle Count"=90,"Current"=3363,"Voltage"=16415,"Flags"=754974725,"AbsoluteMaxCapacity "=3600})
While I'm no expert, I think I have at least some grasp of what it's saying...
Capacity is 64860mAh, which XBattery lists as 64.860Ah... different units, same thing...
Cycle Count is now up to 90... that's fine... I've charged and discharged a few times since last time I checked the count...
Amperage is at 0, even though the menu says it's charging... not sure how that is true...
Voltage is 16.415... not too far off from the 18v listed on the outside of the power adapter... that's acceptable...
For the flags, 754974725 in decimal is the same as 2d000005 in hex, which matches XBattery...
The part I don't get is... if I'm showing a charge of 3363 out of a max of 3600, why is it only at 5%? The only way it could be was if it was comparing the charge to the current capacity... 3363/64860, which is about 5.2%...
For some reason, the computer is not giving it more power, because it's so close to that 'assumed' capacity... 3600 space left on a 64860 battery, which would be around 95% charged... and that's before counting the 3363 I 'persuaded' the battery to accept... But when it checks capacity after I unplug the adapter, it is nowhere close to what the machine was 'assuming' while the adapter was connected...
I would think my computer (or any computer for that matter) would be smart enough to at least pose the question as to why the 'max capacity' is so far below the 'current capacity'... It's like saying 'This basket holds 36 apples maximum, but currently, it's holding 640+ apples... it doesn't really make much sense... There is no situation in which both statements could EVER be true for that one single basket, or my battery in this case...
You'd think an error screen would pop up or something: "The battery is currently sending unreliable and conflicting capacity data, so therefore, time and charge percentage are unable to be calculated in any reliable fashion..." Then it should instruct me on what to do to correct it... Or, at the very least, suggest that I call for assistance... right?
This issue has evolved from weird to downright annoying... I just wish I knew what the real problem was so I could fix it already!

IPad 2 battery meter stuck, anyone else?

It seems after downloading a few apps and putting the iPad to sleep with wifi on the battery meter stops updating the next day when I wake it from sleep. I used to notice the ipad draining by 1% every 9 minutes, but now it has been 20+ minutes and no change. A reset seems to fix the problem, but is anyone else encountering this issue or willing to test? I'm on iOS 4.3.5

Ater a few more weeks of testing, I have noticed several more details about the battery. After a full charge to 100%, the first few % (going from 100% down to 90%) takes longer to drain compared to the rest of the battery. So going from 100% down to 99% took me 22 minutes and towards the 90% mark, I noticed more consistent drainage (about 9 minutes for every 1%)
The second thing I noticed is that downloading apps had nothing to do with the battery meter getting stuck. It just took a really long time (about 27 to 30 min) for it to get unstuck after I first woke it from sleep. This would happen only when I left the ipad for long periods of inactivity (sleep). It would not happen after putting it to sleep and waking it up in 10 minutes (battery continues to drain properly).
The third thing I tried to test was to rule out the battery meter reporting the % incorrectly. If the meter was following a pattern whereby it was stuck at 100% for 30 min and then continued to drain properly, this should affect the ipads battery life. I continued to use the ipad over the course of a week (with the meter getting "stuck" several times) until it hit its final 1%. I was able to use it for about 6-7 minutes before it died. Basically the ipads battery meter was reporting the % accurately (even with the meter being "stuck") or the ipad would have just died at around 2% or more since the ipads battery meter was constantly getting "stuck" over the course of the week.
I think this has something to do with the rechargeable batteries themselves. For instance; after heavy usage of the battery followed by a long period of rest, the battery seems to gain some of its charge back or at least retain a higher capacity (this would explain why the battery meter seems stuck when you wake it from a long sleep). However; after heavy usage and a short rest period, the battery seems to not retain this ability.
I'm not sure if this phenomenon applies to all rechargeable batteries and it would be great if other ipad owners would post their experience (not even sure if anyone else actually takes the time to stare at their battery meter and time it for every % that goes down lol).

[SOLVED] AwesomeWM Battery Meter

Hello all,
I've been rewriting my rc.lua on my netbook for Awesome, and my head is probably just drawing a blank, but I'm having a problem getting the battery meter to show something other than 0% Battery.
This is the code for my vicious widget:
http://pastebin.com/Bt60surG
and I do have the widget showing, it's just always red and says 0%.
I have the acpi package installed, and it works through terminal, and starts on boot, wasn't sure if it was necessary though.
like I said, probably overlooking something, but I have been hacking at it for a couple hours, searching around and what not, and I was like "yeah... forum time" Lol
So yeah.. Any ideas?

If you did get it right check that the data in that directory is complete. Does "present" file contain 1? Does "charge_now"
contain a charge other than 0? If not you could get support for your battery from /proc with batproc widget or worst case
from batacpi widget that uses acpitool. But likely that is not the case, most likely you got the ID wrong.
Wow. That fixed it... When I was looking at it... ACPI was reading BAT0 but /proc was saying BAT1.
Worked. Thanks!

IOS 8.1.2 safari battery usage

Ever since updating to iOS 8.1, my iPad battery life has declined to the point that i have to recharge every day.
the only things i use my iPad for are safari, Facebook, google play books, stock music app, and youtube.
I've checked battery usage, and safari has 90 percent of the battery usage.
i have also factory reset the device, tried to keep screen brightness below 50 percent, and shut all apps, but that makes no difference.
i have also updated to iOS 8.1.2, and it made no difference.
am also considering a nexus 9

i have same problem, than battery percentage jump from 60 to 45 e in this way my problem is very bud. ios 8 last update is installed on my iphone 5. i think that it is a bug software, and i think this because i called apple support and diagnostic realt time with operator say that my battery life is better. and after home button bug fixed with ios 8.1 now i have this. this ios 8 is the worse update ever.

Any ideas on how to fix ipad after the new iOS 7 update? My battery will not charge, my ipad is hot to the touch, the iTunes Store won't open, and my messages on Facebook aren't showing up when I chat and pintrest won't pin to my boards.

If you have all your music on the cmputer then i would connect up my phone uncheck the Sync Music option and apply.
This should take all the music off your phone .Then you can resync the music back on to it.
If this doesn't work maybe a restore to factory settings and start from scratch is the way to go

I upgraded to iphone 4s and installed iOS 6 but now my battery life is significantly reduced. What can I do to fix this problem?

I upgraded to iphone 4s and installed iOS 6 but now my battery life is significantly reduced. What can I do to fix this problem?
I restored my settings my I got the new phone but I think I heard that with the iOS 6 updated that can be an issue and it is better to start from scratch rather than restore your settings.

reset all settings
settings- general- reset - reset all settings
now reconnect to wifi
settings - wifi- click network name - enter password - join
if issue persists backup info and restore via itunes
Peace, Clyde

Why is the battery meter so annoyin?

Ok heres the thin, i got my 5g black 30gig ipod two weeks ago...everythin was fine, until after the first full charge i noticed after about an hour of music the battery meter was down to 3/4 of a charge and kept goin down dramatically, after reading some of the disscussions i did the update and charged it untill it said full, so then after about 4 1/2 hours its in the red, so obviously it still goes down quite fast, to calibrate it at the moment by runnin it till dead, so has anybody else had this problem, and what happened to you....another thing what is the best way to charge it...through an ac adapter or computer.

ok...using my ipod normally (between .5 and 1 hour a day right now) the battery lasted about 8 hours....so it ran for 3.5 hours in the red...this is really dissapointing although it says that it will run 8-12 hours, but also realizing that was the first time doin a charge discharge cycle to try and calibrate it but after charging it the meter is doin the exact same thing...after fully chargin it, the second i start playin music the meter goes down...now the backlight timer is 2 seconds, the eq is off, and the library is on shuffle...and i only change songs once in a while...so why am i only gettin 8 hours?

I have an ipod touch 4th Gen that everything was working perfectly. After the last update of iOs5, the battery have charge 20 minutes. Even after the correction of the iOS 5.0.1 the battery have the same 20 minutes. What I can do?

Same thing here. Try putting the brightness down all the way (its hard to see at first but you will get used to it) and one more thing is that close all you open apps. So to do that you have to click the home button twice (after you put your passcode in) and you will see some apps in the bottom. Hold it until there is a red - sign. click all of them so they go away. This does not delete your apps it just makes your ipod better.

Battery meter reads only 0-1%, or 99%.

OK, well this a little hard to explain but I'll try my best:
Basically, one day a couple weeks ago I took my PowerBook to school and had it in class and basically drained the battery completely to 0%, managing to still continue working about 30-35 minutes after reading 0%. OK, so it powers itself off and goes to sleep. Understandable. I put it away and charged it back up at home later that night.
The problem now is that the battery meter up at top no longer gives me accurate readings on the battery. When the battery has been charging for about as long as it usually would take for it to say 100%, it stays at like 2%. Sometimes, it'll just jump right from 1 all the way to 99%. Ok, like right now it said 2% but now went to 1% even though the AC adapter is still connected and the light has remained on. I have not seen the percentage say anything between 3 and 98% ever since the day I used it in class. It will go from 0-2%, then occasionally to 99% and back to 2, 1, 0. To make this problem seem even a little more strange, before this problem started showing, the computer would rarely start itself up again in the morning without being plugged into the wall first. Essentially, it would become "cold" overnight, and I'd have to plug it in first to the wall to start up. NOW, this thing always wakes up from sleep in the morning or basically whenever no matter how little battery life I think it has.
I got my computer in Jan/2004 and it still has the original battery. Needless to say, I was already getting some pretty short battery life. I'm not sure what the proper procedure on batteries in these things are, if I should have replaced it by now with a new one?
HELP!

(FYI, the meter has now been stuck back at 2% for about the last 10 minutes.)

Try resetting the PMU…
