I have read multiple posts talking about battery life problems suffered after the ICS update. However, my question is regarding the time it takes to charge the phone using a usb. I know the fact that usb charging is slower than wall charging. But what i am comparing is usb charging before and after the ICS update. My phone is not rooted and has the OTA update from motorola. Also, it is a RAZR and not RAZR MAX.
The question is, has anybody noticed that usb charging is slower after the ICS update? I used to plug in my phone with usually 50-60% battery life in the mornings and it always used to be fully charged before lunch. Now, the whole day goes by and it barely reaches 100%.
The phone, the usb cable and the computer are all the same. Only the software has changed.
My initial guess is that the 'charge only' option that used to be available before did a better job of sending more current than the options available under ICS.
Does anybody know of a way to fix it ? With or without root?
Thanks,

I ran into your post after googling the same issue for my cousin; also started after ICS upgrade, but her phone is Xperia S, and its not only affecting USB charging, but even the wall charger is much slower now, more than 4hrs plugged for 30% charge only, when it used to take less than 2hrs for full charge before.
I've always had trouble charging my phone on a computer via USB. It goes way faster when on a wall charger.

there can be more than one issue for this.
1) could be the battery stat. but to wipe this you need to root your phone. Maybe just charge and discharge it a few times completely (till it shut's down automatically)
2) other charging source? are you using another USB-Port to charge it? it could happen, cause your phone has to 'tell' the USB port it's some kind of high power device to get 500mA and not like mouse and keyboard only 100mA. does the PC recognize the phone? are your usb ports unlocked (yeah, i know... even locked ports supports power, but maybe not enough...)?
3) do you charge it while running? or in shut down state? ICS seems to drains some more battery life while running then GB...
PS: charge only option is no more usable but ask an IT-provider to get a 'power-only' usb cable. i've got some and it only provides current, it's like normally charging
PPS: best rooting solution > get Arctic ICS (GSM/CDMA) or Epsilon (GSM) ROM, usb charging in less then 2h! for better result use the 'power-only' usb cable mentioned above
Another essencial tip is always charge through back usb, never in front and disable wifi, gps, data, bluetooth it will make phone charge more and faster.

I agree. Wall charging is always way faster than usb charging but my wall charger usually stays at home. That is why, i use the usb charging option at work.

My phone has discharged completely twice since the ICS update. I am not sure but that might have reset the battery stat. Is there a way to check it on a non rooted device?

The phone is plugged in to a USB port on the computer and is recognized as a Motorola RAZR. I also have the Motorola Device Manager installed which i believe installs all the necessary drivers.
Also, I have tried multiple ports (front and back) and i have seen similar results in terms of the time it takes to fully charge the phone.

I do charge it while running and wifi on. Data, Bluetooth, GPS are off. I always used to charge it this way. Its sad that the same state in ICS drains more battery than GB.

I have so far avoided the root option since i am a little scared of bricking the phone / what if i am not able to restore it back to stock / unable to update phone to future software versions etc.
How does rooting the phone increases the speed of usb charging? Is the software that is being flashed on the device modified in certain ways that is not done as part of the .211 OTA update?
I have also read about the .215 leak. Do you know if the usb charging speeds are different between the two .211 and .215 versions?

For me i don't have any experiences with CDMA phones but what i read was a significant better signal state and battery life in .215 ...
Looks like they improved the system processes / memory usage to get less battery drain. This should be good for charging, because while charging it would drain less battery life / it's charged faster.

Rooting itself will not bring you any advantage in battery drain / charging times. But a rooted phone is open for kernel tweaks and custom ROMs.
Tweaks are used to improve the CPU to get more power or better battery life.
ROMs can be de-odexed / de-bloated to get rid of every senseless app or system process that drains battery while running in the background.
And this improves your battery life AND charge times
PS: There should be some stock ROM from EternityProject as emergency unbrick for CDMA too. Just use the search function, you should be able to go back to stock from every custom ROM.

Did you use Unrevoked or Revolutionary?
Battery stats are jumping and showing inconsistent information
Hello,
I have a strange problem with my rooted and S-OFF’ed Aria for the last six months and I have been trying to find a solution or a fix to the problem ever since.
The battery percentage is always incorrect and never shows any percentage value greater than 30 even after 8-10 hours of charging and drains within an hour phone shuts off. The phone is basically useless for me right now.
I did try all the calibration methods and other solutions (listed below) that I could find in the web and the forums here, but none seem to have fixed the issue.
Soft Reset
Hard Reset
Format System, data, cache partitions
Installed all available ROMs in the community (Liberated, CM 6, CM 7, Stock Original, Stock Update for 2.1, Stock Update with Froyo (2.2) etc).
Battery Calibration of all known procedures (Delete batterystats, discharge fully, recharge fully etc)
Did a task 29 (fastboot oem task 29)
Replaced with a brand new original battery from ATT.
Now with S-OFF, I cannot fully revert to Stock version or send it for Warranty repairs etc (Is there a way to revert to S-ON)?
So now turning on to the experts in this community to help me out and you guys are really awesome in guiding others and fixing things. Hoping to hear from someone.
Btw, I found a similar symptoms and “solution” in the Atrix forum. Please refer link below.
forum.xda-developers.com/showthread.php?t=1198333
Have you tried wiping battery stats, then just using the phone normally? (not letting the battery totally discharge, etc.)
Did the problem only start happening after you S-OFF, or did it happen before then?
It does sound to me like there's nothing you would be able to do about the problem, except reverting to S-ON and sending the phone in for warranty service. Supposedly there is a method for doing this although I have no idea how complicated it would be. You should probably go to the #liberatedAria IRC channel to ask about how to do it.
Thanks for your reply, drumist
Yes, I tried wiping the batterystats and used the phone normally for couple weeks, still no difference.
The problem started months before I did S-OFF, possibly due to multiple format, flash of ROMs etc. Somehow the phone or the battery doesn't know the correct readings/voltage data.
The max voltage on a full 8-10 hours charge that I have seen is only 3.8 v (new and old battery) and ideally it should be >4 v for a full charge.
Thanks,

Yeah. It sounds to me like the mechanism in the phone that is supposed to charge the battery is failing to charge it above a certain threshold. Either that or the mechanism that measures the voltage is failing. You could figure out which one is the case by measuring the battery's voltage with a multimeter if you have one.
I know this is a long shot, but have you tried charging the phone with a different USB cable, or with a different USB power adapter, or by plugging into a different power socket in the wall (or using a different computer if you are charging through a computer USB port)?
Today I tested both batteries using a multimeter and both had voltage > 4 (old battery: 4.19 v new 4.18 v). I tested this after charging the batteries through the phone, so it proves phone charging is working fine and the batteries are good.
Then I went to CWM and deleted the batterystats, pulled the battery out, waited for couple minutes, put it back in and restarted to generate a fresh stats file.
But the voltage displayed in the phone is totally wrong (3456 mv) and showed 20%, so there is something wrong with how the phone understands full battery voltage and percentage.
I waited for the phone to discharge and shut off (which was <10 mins), then checked the battery voltage in multimeter, it was still good at 4.10 v (lost only about .09 mv).
Is there anything that we can do to override or correct the voltage and percentage in the phone?

i'm having the same issue with you, and never find an solution to it.
htc aria
my phone is not getting charged, it shows charging but reduces the charging already present. how to solve this issue
I find that when I tether via PDANet using a USB that the battery will slowly drain depending on how much data usage is going on.
I'm assuming this is normal as it happens with the stock battery & the extended battery.
However, if I do wifi tethering via Barnacle Wifi it does not drain... but then again, the speeds also aren't as fast.
hmmm... õ_Ô
every application is different in regards to battery usage and whatnot. if u like the speed of pdanet, keep it and plug it into the wall. it should be enough to charge through the drain.

well, it is being plugged in while using PDANet... that's how it works. connecting the phone to your PC via USB cable & 'tethering'... so when you say 'keep it plugged in', are you implying that there's some sort of USB splitter cable i should be using to connect my phone to my PC and the wall jack at the same time? õ_Ô
All i do is plug the phone into the pc and leave it for a minute then activate PDAnet and my power is fine...

I've done that before to. It seems to happen primarily when I'm downloading something. If I'm just doing ordinary web browsing then it does not happen.
When I download via wifi, it averages 100Kb/s... and no battery drain
When I download via PDANet, it averages 700Kb/s... battery drain city
The phone gets very hot also(shouldn't be a reception issue since it'll have full bars and get hot). and of course, it does not get hot doing wifi.
I seem to remember reading a few threads in the past about the TB not taking a charge if it gets too hot and basically overheating. I know mine gets really warm when using navigation and plugged into a cigarette lighter. It may be worth it try a different microUSB cable if you have one handy.
I guess moving all those bits around generates a lot of heat
As for battery drain, you may try a different "preferably on the back of your pc" usb port. Of course the rom\kernel your running also has an effect on the heat generated. Just my own personal experiences. Hope it helps
sadly, yes i've already tried different microUSB cables and even tried it on different laptops. i've used both Sense & AOSP based roms with various kernals/radios and have always seemed to have this issue.
maybe i'm pushin' this old phone too much. ;P
(I thought I asked this recently but can't find the post)
OK ... first off GPS / Nav works.
The issue is first off in car use cigarette plug charger, when as a phone only (or playing music via BT) all OK .. battery keeps topped up.
However if I use SatNav the battery cannot keep up .... even though it says charging it slowly discharges ..
I read here some car adapters don't give out full mA current, (that SGS can take) to be 100% sure, I went and bought a 1.5A USB adapter and still the same ... no problem until I switch on SatNav ... then it starts draining ... a couple of % every 15min.
I assume this is simply down to screen taking so much current .... but in very simple terms the phone should be able to keep up via charge when SatNav is enabled.
Anybody got a fix for this ? (screen dimming is enabled)
Ok seems that I am not the only one that is seeing this.
I've owned the S2 for a week and it feels very weird coming from HTC products.
It charges sloooooooow. Also I noticed that battery monitor shows weird values were on the Desire HD it was giving rock solid logical numbers in aspect of Voltage and current.
The s2 sometimes gives me 80% at 3,952 Volts and after a 40min drive 78% and ... 4,012 Volts. It is not stable at all
Just checking the stats in the batt monitor tool.
23:21 at 70% and 3,986 Volts while at 9:00 at 82% and 3,981 Volts.
It doesn't make any sense at all to me
From what I have read is that the charging controller of the S2 is only capable to charge up to a rate of 650mA while the HTC charged at 1000mA (0,65A vs 1A).
Now today I switched off wifi while driving and then it seemed to be very slowly charging. Give that a try and let us know.
Different types of chargers charge at different rates. Mains charges at 650mA, but USB and misc are around 450/550mA. If you're rooted you can change the charging currents in ExTweaks/Voltage Control/setCPU/whatever, however USB is limited as to what it can output anyway, and if you try and force too high a current through, things start to fry.

You would not use a Mains charger when using SatNa
It would be a basic requirement that SatNav use in car would be able to keep charged with a USB charger.?
As the same micro USB port is used, how does, phone know its not on Mains?
In answer to above Q ..Wifi is off, I always turn it off when I enable BT.

OK, that is an 'easy' one. The chargers 'shorten' the 2 data lines.
I've placed shorten between brackets because it doesn't do any harm at all.
I've you install battery monitor you can actually see 'usb connected' or 'ac charging'
As always using waze on my trip to work which takes about 50min.
Started at 58% and went up to 65% when I arrived.

Here is a simple Q then (maybe I'm naive) .. I am not using USB data port to charge, but a car USB charger point (no chance of any data)
Would charger manufacturers not have this 'short; in place as they are making chargers only ?
If not can you provide any details how to do this ... chargers have plenty of current, be good to get phone to use what it can of this.
dont know how to fix your issue but just to let you know its normal for the phone. Im always on my sat nav with a car charger and never been issues with losing any power. Quite often it comes off charge with more than it was plugged in with.
Hmmm.... I'm using original Blackberry car charger for both BB 9700 and SGS 2.
Yes, it charges slow, but with BT and GPS on it does gain on charge/percentage.

I have attached two photos showing an adapter I fixed myself. Look at the image 'charger-bottom-side.jpg' and notice the red circle. Within this circle you can see the short between the two data lines (D+ and D-). The short is simply a drop of tin-solder.

I have now purchased a new lead and charger (to be sure)
Running the App it shows "Charging AC Plugged"
It cannot keep up with current demand when Bluetooth & GPS active ... slowly discharges.
I have had the S2 for about a month now.
Seems like Sygic is the only GPS soft which I tried that doesn't hit the cpu 100% all the time.
I did a test over the weekend and with everything 'on' it slowly charged the phone.
yes
yeah, battery monitor will let you know that.
also suffered from this in the past
I have had the discharge problem using sat nav (Copilot live premium) and a car charger (various car chargers actually). Stock S2 with generic UK firmware. The problem exists on 4.03 and 4.04 - not sure about previous GB as updated to ICS as soon as I bought the phone.
I have found that if I apply battery save mode and turn down the screen brightness the charge just about holds station.
But the strangest thing I have found, although reading around I have not seen it mentioned elsewhere, is that if I enable mobile data the phone charges just fine whilst using sat nav. The problem only arises when I disable the data connection. This came to my attention whilst abroad where I deactivated data to avoid preposterous roaming charges.
This rather implies to me that something is trying to use the mobile data connection when it is deactivated and is causing battery drain when it can't. This could be any app of course, but the problem only rears its head when I use the sat nav (power hungry) with the mobile data turned off.
Has anyone else noticed this? Any advice on narrowing down which app/process this might be would be welcome.

Sorry for bumping into this thread but I think I can help.
Correct me if I'm wrong, but I think your question is:
-Battery charging cannot keep up with discharging rate while using GPS and Bluetooth.
Reason for this problem:
-This occurs because usb charging further is lower than charging via wall charger, hence the battery heroes discharging when the demand is higher than the charging rate.
Solution:
-we need to increase usb charging current to equals the Ac charging current
How is that possible:
1.Root access is needed. If you don't already have root access key me know
2.custom kernel needed.
-You need to flash one of, Siyah, Dorimanx or dream kernel.
-Any of these kernels has the option to increase usb charging current
-move to 3. If you are already running any of the listed kernels.
3.after flashing the custom kernel, install extweaks from market.
-open extweaks
-under "misc", change the charging current to option 3.
Done

I advise not to do that because:
It will not solve this problem as charging from AC is already detected by the device (see above).
The option is dangerous and will enable (if working at all) charging with the higher current limits from any USB port.
good to know

Actually in my case when using sat nav it will charge with mobile data enabled, but will discharge (whilst connected to the car charger/wall charger) without data enabled.
I have searched the forums but not found a thread which is similar to my problem.. I know there are battery drain issues with wifi etc but this is wierd and only started happening a few days back.
Basically i plug phone in to charge and it charges completely normally and quickly as it used to but only charges up to about 68/70% then it basically stops charging any higher, LED still red, charging display over battery still there. Turning phone off, rebooting, unplugging and plugging charger back in all makes no difference!
Any ideas what could be the cause of this? how to resolve?
I'm on stock JB, using the official wall charger and USB cable and i made sure the battery was full when i updated to JB as well.
Try a different battery, these are getting to the point where some will start to fail, six month warranties on batteries for a reason.
Well i have a £1.99 spare battery in atm as i run the original battery completely flat today. Seriously though be surprised if battery fail after 3/4 mths - never had battery dying issues on previous phones i've had until they were a good 2/3 years old.. Always a first though LOL
Its like the battery is saying its fully charged at 70%, now its completely flat i will charge it overnight with the phone off to full (if it gets there) and see if is resets the battery callibration or something.
Try to wipe battery stats via cwm recovery/advanced.

if you are rooted than download batterycalibration and untick 100% charge and click recalibrite and leave the phone on charge and it should charge up nto 100%

It has nothing to do with wiping battery stats. I think Kangburra is right...
UPDATE.
Shamed to say that i am not rooted yet... I have been there and done all that on my old phone ZTE Blade, but i really like the added functions that TW brings and don't suffer much in the way of anoying redraws or lag etc (although i do feel that TW could be optomised alot better along with better RAM Management)
I was going to at least root to sim unlock but got a sim free unlocked phone so had no need, then other stuff i wanted to do like freeze samsung apps etc is all possible without root and i've not come across that "I" need root at the moment.. was going to for APPS2ROM but i got no need to free up space yet.
Cheers for the suggustions though - I have that battery callibration app already (from old phone days) obviously don't work though.
Anyway - I am monitoring battery atm but it seems that running the battery completely flat until it turned itself off and charging overnight with battery off has resolved this issue - maybe this reset the battery stats and recalibrated it.
Its back to normal now, charges upto 100% as normal!! Fingers crossed this was just a blip
So i just played with Custom ROMs to find the best for me...
But from one point my Phone f*cked up the battery detecting...
CM9 and CM9 detect the battery at 45% and then he Level instantly just drop to 0%...
I cant even restart my phone, so i guess the battery really went out...
So how can i fix, that the ROM would not detect it 45% but 3-4% ?
And let me fully chage my phone ?
Stock rom Always Detect it 100% and then randonly the phone shut down in random times (cuz it drops the level to 0%)
I've tried the "Fully-Charge, Fully-Discharge" But the ROM still detect the Battery wrong...
Even tried to delete the battery stats...
Any solution, or idea ?
I currently use CM with the built-in CM9 kernel...
I think its battery problem.use a new battery.ur prblm will be solved

How old is the battery? What charging cable are you using and what is the cable plugged into?
If the battery is more then a year old it could be 'tired' and not holding a charge correctly (trying another known good battery in your phone will determine this, as will trying your battery in another phone, and if it works well you may have more issues to deal with). If you got the phone second hand, you have no way of knowing the battery's history. Repeated overcharging is also not recommended, as well as leaving the battery in very hot places as it can damage the onboard circuitry in the battery.
Cheap aftermarket (non OEM) USB cables are not that great imo, they are generally not as well made and soon get loose connections, resulting in poor connectivity (charging with a bad cable can also damage the battery). Always use the original cable or a good quality aftermarket one, like Belkin.
Charging the phone from a USB port on a PC or laptop (and/or via a USB hub) is not as efficient as charging it directly from a wall mains USB adapter, because the power often gets interrupted. Ideally for the best charge you should turn the phone off and use a wall/mains socket USB lead, so as give a direct, constant, power supply to charge a battery. A typical full charge is done in two hours. If you charge this way and the battery still has issues buy a new one.

First of all, the Phone is manufactured in 11W41 (2011 Week #41) and the battery in 11W39 (2011 Week #39)
I use a tipical Micro USB charger which does not connect to the wall with USB but the cable directly integrated into the adapter...
And the phone's shipped official cable to charge throught my PC...
The battery worked fine before i forgot to delete battery stats and flashed a ROM...
After that, all ROM is getting fake battery data...
After using my phone i noticed:
-When the phone displays 70-80% charge, the battery actually have 10-15%
-When the battery reach 0% the phone not just jumps to 0% but the Phone shut down within a half second (as no more energy)
-When i charge it to 3-4% the phone show 80% again...
-So i can charge it to about 10 or max 15% when the OS detect 100% and does not charge it further more, which prevent me from properly re-calibrate the battery stats, cuz 10-15 will be always the max charge of the battery...
Now i'm looking for some kind of Mod / App that fake the Battery level to the OS (for example lock it to 5% and the OS continue to charge the battery) i know its dangerious cuz if i'm not aware i'll overcharge it and it will die permanently, but i have no better idea ATM...
Update: Sometimes after my phone dies from no remaining electron in the battery It displays 5% charge when i switch it on while connected to a charger (the only way i can switch it on) And starts to increase.. (5-6-7-8 etc..)
But sometimes it instantly jumps up to 70-80% if i think right when the screen switches of..
So i enabled "No-screen-off-whili-on-charger" and letit charging..
Will notice you about the result...

try reflash stock.ics ftf should fix this
Already tried, the Stock rom always showed 100% charge, and when the battery ran out, just powered off...
(Jumped from 100 to 0 instantly)
As i mentioned, in the reply you quoted, today it started charging from 0...
It went good, but somewhy, it just stopped at 26% and not a single volt went into the Battery...
As i Pulled out the Cable, the indicator jumped to 100 instantly...
Can you link several stock ROMs ?
I've tried with the 4.0.4 Android
but maybe the 2.3 can still work with it...

but i think theres some HW damage. even if not rhe battery maybe some config chip is broken or whatever on the board. normally flashing a stock.ics.ftf resloves all software issues, as its resets all stuff to factory..
anyway, here u can find links to other android versions: http://talk.sonymobile.com/t5/Andro...y-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389
