Battery drains quickly... while plugged in! wtf?!

okay so this is a new problem... if I plug my tilt in to my car charger, the battery actually drains faster than if it's unplugged... about a percentage a minute... when I come home and plug it... it charges regularly. I've tried 2 different roms, 3 different radios and 2 different car chargers... any ideas? been doing a lot of soft resets lately, wondering if that would burn the battery out?

new revelation!
okay so after my car charger "drains" my battery... I put the regular charger in and charge it from 74% to 85% in about 20 minutes... then I took the battery out and put it back in.. upon reboot my battery is at 97%... does this mean the car charger is somehow ACTUALLY charging the battery but for some reason making the phone think it's discharging it... this is tricky.

is the battery heating up while it is charging in the car?

I don't think so... I'm not 100% but I'd probabally remember something liek that
I just remember it was dropping like crazy after I plugged it in.. once it jumped from 39% to 34% when I was using it while it was plugged in for 4 minutes

sorry, should have asked in my first post but are you running TomTom or similar?

no, no abnormal software... even turned off the 3g and wifi... I'm starting to think it's not actual battery drainage because of how fast it's dying.... it dropped to 2% and shut itself off last night when I plugged it in.. took 5 minutes to go from 28% to "dead" then when I was charging it in my house that night it slowly went from 0% to 45% then it jumped to 98% and was full.. I'm so confused

Maybe let the battery drain out all the way so the phone won't even turn on, and then charge it back up. I've never heard of this happening before, but I know the phone has to "calibrate" the battery, for lack of a better word. Draining the battery all the way lets the phone set a "zero point". I dunno if it will help, but it would be worth a try.

haha it kinda did that on it's own last night... recharged it, it's got the same problem as of 20 minutes ago.. maybe it'll work itself out.... but I really need to be able to plug it into my car.

This is my second Tilt I'm playing with as the first one after I messed around with started to act funny.
1) Battery would be 100% - I wake up 6 hours later and it's dead.
2) Network consistently was being dropped even though it stated I was connected.
I've spend 5 hours on this site reading now and still don't know if I've learned much lol
Good luck to you...

Check the USB port. Is it slightly bent on the right side? I had this same problem & had to RMA. I confirmed that there was higher discharge using SK Tools & Anton Tomov Batery Meter. However, home charger still worked fine.

YES! the usb port looks a little messed up on the very last pin.. WTF? it looks squished or something... RMA? that doesn't sound good.. I hope I dont have to RMA... what's RMA? but yes there is definately something messed up about the right side of the USB port

Hmm... I would charge to 100% (or near enough) unplug it and then put the media player on and play it solid on repeat until the battery dies. Then charge it up to full again and see if there is any difference. These batteries don't have a memory as such, but as the previous poster said it may have got itself slightly 'confused'

Same problem here with a carcomm cradle for the TyTN II,. When I plug my phone in, the orange light comes on, the phone says it is charging but the battery just seems to drain faster and after a couple of minutes the light goes out. I have BatteryStatus installed, when I connect the phone to my pc with the standard usb/synch cable BatteryStatus shows +0mW for a short while and after a few seconds it'll say it's at +1300mW or something like that.
In the car when I put the phone in the cradle it'll show +0mW for a few seconds, then around -250mW (Idle) and the orange light turns off...
But I actually caught it charging once with +22mW when turning it on (from standby). I tried all obvious things, softresetting the phone while charging etc. But nothing helps, the cradle is connected straight to the carbattery.

check your USB port... is your's messed up too?? you know what? I probabally accidently poked the stylus in mine while trying to reset a couple days ago... since I tried to do 20 resets when I was rom upgrading and adding software...

Just checked and yes it is, stylus thing happened to me also once....
It's a little bend downwards (when having the screen on top) @ the last 2 pins...

well looks like we've narrowed down the problem.. and it looks like the fix is gonna cost $80!!

What kind of carcharger do you have? Been reading about this problem and alot of ppl say the charger needs to be able to put out at least 1A for the phone to charge, I used some cheap cigarettelighter charger that was rated @ 650mA. It worked but charged so slowly that it would've taken days to fully charge. And besides that it didn't last long, 3 days before it blew the fuse and some more parts (worked for 2 secs after replacing the fuse)

I've tried several different ones... I think that since 3 people on this site all seem to have a "crushed" pin in our USB ports that's probabally the issue... now.. about a fix...

The amperage on your charger doesn't really matter. 1 amp is recommended so that you can use the device while charging, and the rate at which the battery charges does not diminish. If you used a 500mA charger, and had wi-fi & gps on, and media player blasting, for example, the battery may not charge at all because all the power coming from the charger is being used immediately. 1 amp chargers remedy this problem. Hope this makes sense, I've been having problems finding the correct words to express my ideas lately. Probably just stressed out! It sounds like the bent pin on the usb port may be resulting in a V+ pin shorting to ground (or V-). Which would drain the battery quickly. When you use battery power or charge the battery, it is normal for the battery to get warm. When you plug yours into the car charger (the one that drains it) does the battery get abnormally hot? This would indicate a short. Maybe try to put a real thin piece of film or something under the bent part of the port to insulate it while charging and see if that fixes it. This might offer a temporary fix until you get a new port. Maybe you could spend some time learning how to solder! I had to fix a broken port on a wizard a those solder points are friggin' tiny. Hope I could help. Good luck.

this sounds like it makes a lot of sense... I've got big clumsy hands, man I wish I had been more careful... well looks like I'm gonna be out $80! but quick question.. why would the wall charger operate normally while the car charger reverses charge?

Kaiser stops charging with HSDPA when it overheats (+)

Ok, I've been trying to get to the bottom of this problem for a long time.
I've got unilimited HSDPA GPRS on my Tilt, so I tether to my laptop. Kaiser is connected through a 1Amp powered USB hub to a laptop. Tilt was just lying on the desk, and I noticed several interesting things:
1. If Kaiser is at 100% charge - the green light (power) will stay on for a long time, about 40-60 minutes.
2. If Kaiser is NOT at 100% charge, it will charge (orange light) but won't reach 100%. It will stop charging in about 20-30 minutes.
3. If I put Kaiser on a cup, so that there's nothing under it and air moves freely all the way around the Kaiser - I get around 40-60 minutes of charging even when battery is less than 100%. If it is 100%, I can get up to 1.5 hours or so.
4. Whenether it stops charging - I notice that the back of Kaiser gets pretty high.
5. Every 40-60 minutes the charging light comes on again and charges for about 10-20 minutes (gives couple % to battery), then comes off again.
6. BatteryStatus app shows:
6.1 When charge light is ON: + some MAh, don't remember exact number, but it's like 10 or 20.. very low charge
6.2 When charge light is OFF: full battery drain, -400 or somewhere around there (can't remember). It seems that power flow through USB port just stops, disconnects.
7. I see same results when using car charger and stock AC power adapter.
8. Traffic definitelly affects it. If I just have HSDPA on and not using it - it charges fine, it seems. When I start using up the traffic (download files, watch TV, etc) it starts to heat up and stops charging after some time.
It seems to me that the problem with Kaiser stopping to charge when using HSDPA is caused by heat. There must be something on the hardware that turns off charging if the processor/MB/hardware is overheating. I guess charging the battery generates more heat than using the battery, or why else would it turn off charging when overheating?
Just thought that this, perhaps, would be interesting to some developers or people who have the same problem. Maybe someone can put Kaiser in front of a good fan and see what kind of result does that give - maybe it will keep charging.
Assuming that this is true, I don't suppose a fix is possible. Except for, perhaps, switching to slower connection (not applicable in my case) or putting kaiser on a bag of ice.

What does the Batterystatus app read in all above situations?
Since I exchanged my Kaiser, I don't feel the unit getting hot anymore. The previous unit used to get v.hot using wi-fi and 3G/HSDPA - Possible fault?

Scary... I experienced this for the first time last night. Was streaming some vid from my tversity server whilst on the mains charger. All of a sudden my Kaiser got extremely hot. I immediately stopped streaming and let it cool.
I don't think it stopped charging though but I guess it makes sense that it would be protected against overheating.
The only thing I can suggest is try charging with .5 amp... not actually sure that it would charge too well at that though, especially if you're giving it a good workout at the same time.

Try without that 1Amp powered USB hub to a laptop....
1Amp is max i gues... so maby it's giving less, so it take a long time to get from 80% to 100% and yep lot off heat....

I don't use it anymore, but before, if I remember correctly, it showed around small charge (+) when light is on.. then, when phone stops charging it used to drop to full battery drain, around -400 MAh or something like that.
So you got a new Kaiser and it doesn't heat up when using HSDPA? Really?! Have you tried using HSDPA for a long time (actually using the traffic like tethering, MobiTV, etc..)

I see exact same problems when connected to a AC power supply that it came with. Same problem when using car charger.. and same problem when powering by USB without the AC adapter.

Here's my theory... Lithium ion batteries have on-board microprocessors to protect the battery and device from damage. If the battery gets hot the processor will shut down the charging to prevent damage. No matter what tweaks you do to the device or modifications to the charger this on board processor will override and shut down charging if it deemed it was necessary.

No, I said the replacement didn't get hot - read uncomfortably hot - It does get warm, but only in the same way it does when taking a long phone call. My first kaiser used to get extremely hot when charging which indicated a short somewhere. All is well now though.
I hope you can get this sorted though - are you able to get a replacement?

Ahh, I see.
Yeah I think I'd be able to... but mine doesn't get "extremely hot".. it's just.. warm to very warm. It seems normal for me, don't think it's heating anymore than it should.
Have anyone had this problem with 3G (not hsdpa)? Cuz if it happens in 3G as well - that means another reason to be pissed at HTC - they've design kaiser in such a way that you cannot charge and use HSDPA at the same time.

This problem can be easily recreated and a result from other user would tell if it some device or not.
HSPDA with streaming music while charging = warm
HSPDA with streaming video while charging device = Extremely hot
At this point the USB charging will shut off for whatever reason. I just wondering why the phone is putting out that much heat and can it cause problems since I am starting to stream video via HSPDA while charging a lot.

I was just thinking that on some systems it might have interfered with craptive sync. I never guessed that it was because of direct charging issues.
Do you still have problems if you are plugged into the OEM charger, and not a USB port or hub?

Yep. I tried tethering through WiFi (successfully), and same result. Maybe even heats up more, since now there's one more module to power up.
Somebody told me some time ago that iPod charger fixes these problems... can anybody confirm that?

Hmm.. sorry, but, are you sure? Try tetheting through a powered USB and.. I dunno.. do a big download or something, play an online game.. do something traffic intensive.. it should stop charging.. if it won't - hell, please let me know!

i have an att tilt with the stock rom minus the bloatware.
when i installed battery status (basic version) i noticed that my charging became extremely slow. with the ac charger after the battery status install...it registered +350ma, then it fell to +110ma and wouldn't go any higher, no matter if i soft-reset or not...sometimes it was simply 0. i tried usb connection, ac connection, it didn't make a difference. the charging crawled along slower than i had ever seen it. 39%...40%..........41%. i had enough and i deleted battery status and softreset.
when i rebooted the phone, the battery immediately read 100% (from 41% before the reboot)!!!! and the charging was back to normal.
so my suggestion is to see if removing battery status...and see if that helps?

I never got teathering to work through USB. I'd either teather through WiFi or BT with the a/c charger plugged in. I'd imagine teathering through WiFi would be the worst. Most times I teather I'm just reading email, visiting various forums, and on rare occasions I'm downloading music. I'll have to try later and see what happens while I download music over a teathered WiFi connection...

My Kaiser was absolutely baking last night.
I have a stuck pixel so was using a video that I found somewhere that you play on a continuous loop. The phone wasn't completely flat when I started playing the video but within half an hour or so the low batt notification popped up so I stuck it on charge (supplied mains charger).
I was connected to wifi but wasn't actually doing anything with it (video being played from sd card), in fact I wasn't even using the phone, it was just sat on the side charging and playing the video.
About an hour later I came back to the phone to find it was extremely hot. So hot the heat had travelled right through the phone body and even the screen was hot to touch and the battery was still flat so had clearly stopped charging.
I immediately switched the phone off and removed the battery, even then it took an age to cool down.
I don't know whether to get on to Orange for a replacement... I don't think it's right that it should get that hot.

This has been discussed before but some nice new information is coming out in this thread that ties a few things together.
The Lithium battery does have an onboard charging management system that will stop charge if the battery overheats but also if this heat is combined with high current drain. This should be at a precise point but I have experimented with three types of battery and get very different results between the three AND also between batteries of the same type.
The best performing battery seems to be the latest Samsung (P/N 35H00086-00M) with the external 'X' shaped heat spreader on the back that connects to the four earthing points in the battery compartment. Ealier batteries and some 3rd party batteries have this earthing spreader covered with potting compound or even omitted.
One other item I have found, a 1A rated USB port does not give a continous 1A output. Most ports are only rated at 1A surge and will only give out approx 600mA continuous before IT'S own thermal management system cuts off and kills the USB completely, this is probably the cause of comms loss by some people.
Nice informative thread DarkDvr.

USB Charging So Slow Almost Not Worth It

Is anyone else having this problem?
Any work around to having it actually charge the battery up?

it uses electricity faster than its recharging its crap! ive never known any device do this. When im low on battery and have it connected to my computer i have to switch it to the mains for 30 mins. Its terrible, bad design fault

I have the same problem with my Toshiba G900 (WVGA too). Very slow on USB, but normal fast at standard charging or car charging. USB is very bad for this at all.

it really depends on what you're doing with the phone, its unlikely to charge when busy, its a lot faster at charging than my old advantage, im actually impressed!
have you made sure that you've not ticked turn off charging whilst connected to a computer?
charged in under 3hours whilst on connected to ubuntu yesterday.

don't u guys realized how many amperes that a USB socket and your PC (as well as the power supply) allowed compared to a wall socket?

usb chargin usually is never worth it.

I don't understand your disappointment, usb voltage/ampere are the same for all devices, even for my touch when used as modem doesn't supply enough power for charging seriously

Does it even charge at all via USB when the X1 is on idle? If it does, how long does it take from low to full?

I left my X1 idle on USB for 6 hours, it was nearly flat when I put it on and after 6 hours it was still 1 bar below full. Whereas my LG Viewty fully charged in about 2 hours. My Universal only takes about 3 hours
So in my case, comparing the three phones, you can see where my dissapointment originates from.

True tho, point taken.....dissapointment level aleviating.....slightly....

After my phone beeped saying the battery was low, I plugged it into my USB hub (which has a mains supply). An hour later I removed the cable and the phone beeped again.
At least with my P990 I was able to gain some charge, it seems like with the X1 it just stops the battery running down.

Try it after Softreset again. I had this problems with an old ROM on my G900 too. After some time it did not charge. Softreset fixed it.

also yall are forgettin that it's a different kinda battery in the x1 compared to other phones it's ising a li-po compared to a li-ion (which is in most other ppc phones) it charges slower via usb because it's tryin to keep from exploding any extra surge that the usb gets could cause your phone to explain
the li-po is more likely to explain given the way it's built
when you use the wall chargers and car chargers the connection are ment fron rapid rechargin of the device unlike the usb which is for data transfer mainly
when you think about the charge time just think about how long it actually takes for your phone to run out of battery life from what i heard it's close to like 1.5 to 2.5 days compared to normal ppc phones that last probably a day at the most with out recharge

also yall are forgettin that it's a different kinda battery in the x1 compared to other phones it's ising a li-po compared to a li-ion (which is in most other ppc phones) it charges slower via usb because it's tryin to keep from exploding any extra surge that the usb gets could cause your phone to explain
the li-po is more likely to explain given the way it's built
when you use the wall chargers and car chargers the connection are ment fron rapid rechargin of the device unlike the usb which is for data transfer mainly
when you think about the charge time just think about how long it actually takes for your phone to run out of battery life from what i heard it's close to like 1.5 to 2.5 days compared to normal ppc phones that last probably a day at the most with out recharge

Err... this is not true for TP. TP lasts about 2 days on average from normal daily usage and it doesn't have problem charging via USB. Given that the port used is USB 2.0 not 1.1 or below. Took about 2~3 hours from nearly flat to full charge if I remember correctly. I have to try again just to make sure. But definitely not taking 6 hours.
I would've thought that X1 shouldn't have any problem with charging since the battery is only like 150mA more than TP. Also, if it's charging faster from the AC adapter, the same result should be expected when charging from USB port. Doesn't matter the type of battery used. Unless if X1 somehow limits the charging current on purpose when PC USB port is detected. Even though USB 2.0 is actually capable of giving out 1.5A maximum. Try to soft reset it after charging for about 2~3 hours. See if the battery gets fully charged. Some TP users are experiencing this issue as well when the battery meter only updates to fully charged after doing soft reset. Experienced users might want to try and measure the current drawn when charging via USB 2.0 port.
Hope this helps.

On my xperia if i put it in sleep mode, it charges no problem using USB.

the advantage used to charge slower from a usb port, that is until someone found out that the standard ac charger had a short across two of the usb pins, and with a quick mod of a usb cable charged quickly from the usb on a computer
however my x1 charges the same from usb or mains, I use the same cable, but can't see what difference that makes.
there are three conditions that affect charging speeds, whether device is on or not, off charges much faster, whether screen is on or not, screen off charges faster, whether theres good radio signal, if like at home, reception is dodgy it can really draw a lot of juice.

Just for comparison sake, I did a test on my TP just to confirm. Charging via USB 2.0 while it was on idle with screen turned on, from 4% to 100% it took about 2.5 hours and its battery feels warm.

Ok lets clear out some things.
A standard PC USB socket can provide maximum 500mA (milli-Amperes) Current at 5 Volt. Ideally that means that a battery rated at 1500mAh (milli-Amperes-hour) can be charged around 3 hours (minimum). Now, subtract the current that the xperia needs while operating and you will get how many milli-Amperes are left for charging.
Of course in order to know how many current the xperia needs to operate you need to connect an ammeter in series, also keep in mind that current needs change depending on usage (wifi, 3g, bluetooth etc).
So in essence if you USB port is not very good and can't give fully 500mA and the xperia needs a great amount of current to be on, then the charging time can be quite long. A simple formula could be:
xperia_Battery_mAh / (USB_Current - xperia_Current)
Now the mains charger is rated at a greater value than the USBs 500mA. Actually I don't own yet an xperia (waiting patiently to arrive), so I don't know how much current the charger can give. Can someone see what is the rating of the charger?
From other devices I own (that can charge through USB) I've seen that their chargers are rated as high as 2 Amperes. Obviously these devices never draw so much current, it is just a failsafe or it was more cheap for them to bundle a charger like that. But they could draw 800mA of current which the USB port is unable to do so.
Keep in mind that while charging with USB might be longer, generally it can be safer for the battery (longer battery life and more charge/discharge cycles), although I am not so sure about this with excessive charging times in a USB port.

Ultra slow baterry charging via dock M36H

Hi, I would like to ask if there is anyone of you happen to be via a docking station charge the phone for a long time ? Yesterday I played Real Racing 3 which understandably draining battery as hell , so I put the phone in the dock station and keep playing RR3 but battery had been keep drained so I turned off the game and tried simply just looking over the net with the phone still embedded in the dock but situation has been the same percentages keep going down . So I turned off the display and let it charge if it stabilizes . I've found that one percent will be charged in 5 minutes which means over eight hours to full charge . I've tried to force kill Smart Connect (I've read that might be solution for this unusual draining) but nothing hapens...even about 2 times that process Smart Connect itself again launched and let notification popped. Otherwise I've tried to kill all applications to sure that no application is taking battery time. My charging set is :
1x Dock M36H
1x USB charger original manufacturer
1 MicroUSB cable length 2m (buying longer because of log distance of the socket)
My observation is that it could cause just that long cable because when I charge the phone with shorter on one side connected to the dock and on the other side to the PC and it worked flawlessly , and the phone has been around for 3h charged . Do you have some experience with it ? Or cable length does not affect the charge? Thank you for your insights

not only the length, the built quality is important too (armoring and connectors). the more tick it will be the better results you'll have (transfer speed and charging efficiency). for the dock I advise a cable of 1 meter only if it's cheap.
Made in ZR

To further test and see if your extension cable is faulty:
connect the extension cable directly to the phone itself, not the dock and see how fast it charges compare to the stock. You can also download the app called better battery status as it shows the actual charging current. by comparing using just stock cable vs added extension, it should give you a better idea.

[Q] Battery drain while using the phone connected to wall charger

Hi all, I have never experienced this kind of wierd issue with any of my past phones. When i would play games or say watch a movie on phone,( my last one was Htc One X), i would usually connect it to a charger so that the battery keeps charging slowly, and it worked with each of my past and even my gf's galaxy s4. But with XZ, the battery keeps continuously discharging. Anyone got any fix for this? With the kind of weak battery XZ has, it is a highly needed basic feature. I even tried with a 2A S4 charger, but to no effect. I even tried the modding of usb cable by shorting the data wires (the green and the white wire cut and insulated), still no improvement.
I have been using existenz v1.5.5 kk, and i can see that there is an option of fast charge in performance control. But turning it on doesnt make any change. Does the kernel not support fast-charge?Can anyone share any insights? It feels stupid to have to lay the phone down letting it to charge by itself olny to get all discharged within 3 hours.

Charging is really a problem for XZ. Anyways, shorting the data wires won't help, try switch to a stronger cable that's capable of transferring larger amount of electricity when you're using the 2A charger (many of those cables aren't able to transfer enough amount of electricity).
Also, when your phone is really fully loaded and became very hot, just as when you use it for navigation in your car under the sun, the charging speed will decrease (I don't even know why). The charging speed decreases either when you're touching the screen or when it's hot.
Anyways, try better cables first and see if it helps. The docking system is also likely to charge faster.

I used a whole bunch of cables. The HTC one actually works as an anti-charge cable lol, it eats up battery even when the phone is left on charge unused. I had high hopes with the S4 cable, which turned out to perform same as the stock Sony one. Guess I have to live like this..

Sorry to hear that the cables you tried all failed. Did you try using the docking system? They should perform better though.
I mentioned switching cables because I had a "anti-charge" cable before, lol. I did some research afterwards and finally got some 22AWG cables and they really made a difference. It's said that they're capable of transferring 3A electricity and it's really different from all other cables I've used. They're just about $2 each because they're handmade, I can give you one if you wanna have a try.
Also, charging by AC power should be better than using the power of cars' lighter. I'm using my docking system with the SONY stock charger w/ ac power. Never disappointed me.

Dude you might not be able to give me even if you wanted to.. I am in india and the shipment cost will be excessive. Thanks a lot btw.
I flashed Carbon KK rom and the charging is comparatively better. Atleast it doesnt drain while i use the phone for browsing etc, connected to a wall charger. But if I play games or watch videos on speaker, it does to some extent. I bought one more charger, a Nokia made 750 maH charger (AC 20N) which again is wierdly same in performance compared to both the 1.5A Sony and 2A Samsung. What I think is as you said, the wire makes all the difference. A 2A non detachable is the need of the moment for XZ it seems..

Anti-charge cable?
Xperia™ Z (C6602) with Tapatalk

From my experience usually Google Play Services is the culprit for hot phones and battery drain. What I did when on stock 4.4.2 was i uninstalled updates for the services and my battery life improved by a lot. Although it does come with the downside that some apps like youtube won't work with the older version (easy work-around by using chrome to go to youtube instead =P)

Since I own that phone, I've been facing the same problem of slow charging speed (actually discharging when using some applications)
The more problematic case in when I'm using the phone in car when driving even if I'm using a powerful car charger (Anker).
In the past I also have tested number of diffferent charger and cables (including original Sony car charger) without seeing *any* improvement.
Recently I've decided to took time to make a comparison test with a colleague Nexus 5. We have connected it in my car to the same charger and used in the exact same configuration (Waze navigation app running) for a one hour drive on the same work->home daily path where I use usually my Xperia.
The measured results have shown for the Nexus a 30%/hour increase of battery level opposed to the Xperia 10%/hour decrease I'm facing every other day.
Later, using "Android tuner" application battery monitoring tools, I've been able to measure that, even when using a 2.2 Amp capable charger, the Xperia isn't able to "suck" more that 700/800mAmp input current most of the time.
To go further I've asked in the french forum where I've posted those figures if any people had been successful to have the Xperia battery level increasing in the same configuration. I have got only answers of other people acknowledging having the same problem as myself.
Then I've also asked people in the "accessories" section of a car owners (Toyota) vehicle forum: found people having the same issue are also owning Sony models.
Also asked another colleague who who owns a Xperia model Z1: ditto.
I definitively start to think that there is a defect is a in the battery charging regulation system of the whole Xperia range.
BTW: I will be very interested if anyone using an Xperia Z in car with navigation application running without those issues could post details about his charger brand and model, and how much battery percent/hour increase he his actually getting with that setup.
Sorry for the long message and thanks for your attention
