Hello, My phone problem is, whenever i charged my phone to any certain percentage like 80%, 90%, 100%, and unplugged the charger and using the phone, first 5-10 minutes its consume 5-6% battery and first 1 hour of using its consume 10-12%.
This problem happening to all roms including stock rom
So it's not your 'roms'.
Tell me about your fone, how old, and what type of battery?
Does the fone heat up at all when it's draining?
Is there an extra slight BULGE at the back of fone?
I know some charger's, like the iphone chargers, can and do lose their amperage, it's how they sell more charger's, by providing the volts but not the required amps, or in this case, milliamps.
Let me know, and I'll try to help quick as

My phone is 11 months old, and the battery type is Li-ion battery
no heat up while charging and discharging
cant sure is the phone slight BULGE at the back of fone?
By bulge, I mean, does it feel slightly fatter? Bigger? Swollen? can you take battery out, if so, is it neat and tidy, as in, lay battery on a flat surface, it should be flush with where you place it. If it's flat, turn it over, is it still flat?
Have you had any recent updates?

no its not slightly fatter and my phone has glass back panel.....yeah got new updates,but the problem is on every roms
but some custom kernel like etherious and agni kernel...the battery draining normally
So if your battery was getting fat, it would be time to replace it, but due to glass back, you cant tell.
Do you standard charge, or turbo charge?
Back in the 80's, I learnt a fantastic trick, read:
Batteries develop 'memory'. They remember how long they were charged for, in that they kind of copy the previous charge, and dont go further than where the previous charge was halted. Meaning if I'm in a hurry, and pull out fone at 60% charge, next time I plug it in, it MAY see the 60% previously disconnected, as full charge.
For instance, I buy a new battery, when I get it, I dont know how long it sat on the shelf for, as it's charge slowly dissapaited through non-use (yes this happens) while sitting on shelf. So when I get the battery, the first thing I do, is place an electrolytic capacitor (valued around double the voltage of the battery) and place negative of capacitor to negative and positive to positive on battery, the idea being to drain it completely. Once I get no power from battery, I then charge it for 24 hours.
This erases the 'memory' the battery develop's, making it like new from factory. The above is the 80's version of recycling a car battery. But you cant drain the battery, being sealed in your f'n, so try the following:
Grab a usb adapter, say a 4 port (mines a 7 port), and plug your powered on f'n into it, whilst filling the other ports with any other usb devices, the more power they need, the quicker you drain your fone., being the objective.
Do not plug the usb port itself into ANYTHING, and do NOT apply power to the hub.
Leave until nothing lights up plugged into the hub (have a thingy with lights plugged in to see the power drain).
Look for a 3.5mA usb charger, the type used for tablets, the amazon fire tablets charger is ideal for this. Once you have completely drained battery and know nothing else works cause your fone cant supply the other devices any power, plug your f'n into the 3.5 mA (milli-amp) charger, and charge for 48 hours.
This is the electronics engineering method of renewing a battery.
My scource is an old '80's magazine, co-incidently, I'm in same edition called CB magazine, the first ever printed version of how to make a battery like new. I hope this works, cause I dont know the actual fone, but if you do this, you'll have the added advantage of knowing you just 'made' a new battery, and learnt not to buy sealed fones where you cant release the battery to swap it.
As I say, if it's a hardware problem, you'll know after this.
Edit: I know apple mess with the charging cycle to make people buy new iphones, which they do in updates. Your problem MAY actually be this.
Good luck!

So in short You tell me to do that is, i have to connect a usb hub to my phone and discharging all the battery. then i have to charge my phone at least 48 hours/2 days?
Yup. If you take your time, and it's not hardware or update related, you'll be glad you did. At the very least, you make your battery brand new for sure.
Whilst googling, I found some saying some optimisation service wont stop, but hey, it's now down to you to help yourself

don't take me wrong......so the methods u told, really improved li-ion batteries..
and also i dont have any 3.5 ma charger....can i charge my phone on pc usb port
and when charging 48 hours, do i have to turn on the phone or charging with switched off

Yeah it works with EVERY battery made by man, unless it really is DEAD, like no acid to react to the li-ion, shame we cant add water like the car batteries of that time to prolong the battery life lol, back then was poor days, lots of handy finds were found...
I would not recommend the pc/laptop method, because I'm pretty sure those usb ports only provide 50 ma (a quarter of 2.0 mA, note the small ma compared with the 2.0 mA)
Power to pc/laptop end user style is 2.0mA devided by amount of ports.
Any single charger rated 2.5mA or above is what you want, so I use 3.5 mA.
Check old big phone chargers, look at the plug, go for more power than your actual fone charger, which I must ask, is rated at how many mA? I predict 2000ma (2.0mA)
The time (2 days) is to FORCE more power into the previous 'rememberd' memory, literally blowing it's mind lol. After this, you use your standard charger, this is only to fix BATTERY, so then we know if it's hardware or software, cause you did the work and patted yourself on the back lol
Edit: keep fone off while charging, just use another old one or borrow one till the charge is complete. By cheating you only cheat yourself lol. By doing, you WIN.

my phone charger is 18watt fast charger....than how many ma it has....and how many watts in 3.5ma charger??
Glad you asked. Your charger is a 2.3 AMP or 2.300mA like I said, try a larger charger
Look at charger till you get what I'm saying re: ma, mA or Amps (A)
2.0 AMP is 2000mA
To make it easy for you. 2.0 ma (how it's sometimes written) is = to 2000mA or 2.0 AMPS, but do NOT make the mistake of using 2000 AMPS lol, I'll hear you from here...
Electronics is defo not software and I forget sometimes i'm dealing in milliamps and amps, etc rather than megawatss from my radios lol
So you will look for a plug that MAY show EITHER 2000mA or or 2.0 AMPS. The old way to write milliamps were once similar, so ma was made mA to show amps. Keep my age in mind lol

hello all,
i have spend the last 24 hours searching this forum, as any true newbie with an XDA should i got mine from a friend, but it was not used for over a year, so the battery was empty. i recharged the phone, but it won't turn on. i have readed a lot of topics here about phones that only go into bootloader, but mine does nothing at all. when i put it in the charger, the led turns red first and then orange and stays that way. it also won't turn on while it's in the charger.
i tried a soft and a hard reset, several times, i checked the battery, it gives 2.8-2.9 volts, i also tested the sim door switch, but that also seems to be ok.
also when i attach the USB cable to my pc (windows XP SP2 prof) it detects a device, but cannot make out what kind of, active sync also cant find the xda.
i don't know many more specs about it, cause i have not yet got it running. anyone got any sugestions for me that would bring back the phone to life?
greetings and thanks in advance!
These units tend to use a Lithium Ion battery:
If the battery is left plugged in and not charged for an extended duration, they tend to die beyond repair. Even though it says it may be charged, it is probable that it is not, and the unit will not power on without a certain amount of charge.
Is there any way you can try a known good working battery??
i know a few things about batterys too, so this thought had crossed my mind allready, but i hoped the xda would be able to run from the charger, so i could see if it was working.
the battery is coming back to life real slowly, but i think i'll have to look for a new one. the voltage is 2.93 volts at the moment and coming up with about .1 volt/hour. i think it needs to be 3.6 volts (like most lion accus)
tnx 4 the msg, if anyone has any other suggestions, would love to hear them
ps. maybe someone with an xda can measure his battery voltage for me so i can compare? you can check it on the back of your XDA with a simple voltage meter, just take the cap of the contact pins for the external battery and use the most left and most right pin.
Don't know about the XDA, but my XDA II does not run from the charger if the battery is removed or really flat - if it is really flat, I get nothing but a red lamp for a while till the charge has reached a certain level, then the unit turns itself on.
Just gonna review some of the accessories I have used and what i think about 'em
First up is the 3500mAH extended battery by HHI
This battery came in at a cost of $9.99 with free Shipping! It showed up with an 80% charge which is in the acceptable range of where they like to sit. The battery performs just as one would expect it too. I am currently running MeanRom, and can easily get 16-20 hours of use with some really heavy gaming. However I recently went on a vacation and wanted to run the battery through a couple different variations of "discharging". So with the phone in Airplane mode(no radios connected) and very little use i easily can get a week out of the phone without charging. Again this is without any radios on, not connecting to anything.The stock battery cant touch these numbers. i would be lucky to get a full day out of the stock battery with no gaming and normal use.I didn't do a sticker pull to run the numbers. So I'm taking HHI's word on the 3500mAH being just that.
To conclude on this battery the $10 investment turned out to be a good choice, although it might not be a seidio or something it does more than i expected it to do. I will continue to use this battery till I get rid of the phone. The battery can be found here.
To continue on the batteries,
I also bought some of the Galilio "2000mAH" batteries, I got 3 of them with a wall charger for $13.99 on ebay, as reviewed by many others.
This is my experience with them. So they showed up in the mail and upon opening them i discovered one of the batteries look like it got dropped or skipped accross the cement, im not sure what happened, but who is gonna put a messed up battery in their phone.. So i really only got 2 batteries. I brought it up to the seller he offered me $3.00 back, it wasn't worth my time even dealing with that any further at this point. Anyways the batteries Are nice little backup batteries i take with me on trips.They make for easy backup batteries. The batteries have been suspected to be somewhere along the lines of 1000-1200mAH. I would have to agree, even with no testing with any type of tool, besides my phone. They last a most couple of hours. The wall charger that came with them actually surprised me. Everyone was reporting that it may overcharge your stock battery, which can cause some issues. This charger(as pictured below) will charge the Galilio batteries to 100% with no problems. I put my stock HTC battery into the wall charger and with repeated attempts the charger will not charge the battery past 85% even when i left it on the wall charger for 2 days. I do believe that the stock HtC charger that came with the phone gives the batteries a "better" charge, but the wall charger seems to not charge the batteries past a safe range as everyone seems to be reporting as a possible issue. My issue is it doesn't charge it well enough.
I've attached some pictures of the battery results and of the batteries.
Reserved for more... case reviews coming up next
i got the 3500 mAh from HHI. great battery, even better price.
Yea that battery is awesome!

Going to try this battery out. Thanks for the review.
The 85% is charge limit is what a cheap charger do,
The "charger" that come with the phone is simply a power supply, the charging circuit is actually "built in" to the phone. You can connect the OEM HTC charger/power supply into one of those cheap aftermarket dock that charge a 2nd battery and it will never charge the battery past 85% either.
To make it short and sweet
There's 2 stage of Li-ion charging
1) charge to 4.2v at constant current which is 85% when it first reach/near 4.2v
2) saturation charge, once the battery reach 4.2v, continue charging but at gradually reducing current until it reach about 3% of default charge current
Cheap charger have a simple/cheap circuit and cannot do stage 2 charging, where the charging circuit built into each phone would do stage 2 charging

Just notice this, just now i see this screen when charging with phone turned off. I try 2/3 different charger from other manufacture still the same, but all charger works when phone On. Any solutions will help. Thanks.

That indicator means the Streak isn't recognizing the cable, so you have one of two possible causes here:
1. The cable is bad
2. The port is dirty or bad
To properly troubleshoot, clean the port with a cotton swab and rubbing alcohol. Let the port dry, which should only take a couple minutes or so. Then plug the cable into the port. If it still doesn't work, try another cable. If it still doesn't work after that, the port is likely your culprit.
will try. thanks.
edit ; but, just found that if connected to the computer when screen off, it's charging properly. So this is maybe charger incompatible issue ? i don't have original Dell Charger, so from the day i hold this lovely device i use random wall charger adapter from my blackberry, LG and iPhone.
Sent from my Amazon Kindle Fire using Tapatalk 2
you know.. it is quite bad to mix use of wall charger.. since it would affect your battery... try to use just one charger and stick to it... i use samsung galaxy tab original charger with rating 5V 2A by the way...
Ya i think u right. 1 more question if you don't mind, sometimes... i just need to 2-3 hours to perform full charged. But somestimes ( usually in some miui ROM ) i need more time like 4-6 hours to full charged. Whats that ? I try using Battery-Calibrating apps from market or manually deleted batterystat file, its result randomly, sometimes working, sometimes not. Can you please explains more about battery... thanks.
Sent from my Amazon Kindle Fire using Tapatalk 2
usually when we flash rom over another, the previous battery stats would be used... so doing a recalibration would help to get back the actual battery stats...
so.. when you notice the charge length is not correct or it is not like usual... doing recalibration would help..
charge half way... or you charge and then forgot bout it until the next day... something like that would affect the battery stats also...
if you maintain the charge cycle appropriately .. it would help the battery stats maintain the correct value too...
i also sometimes forgot bout the battery.. i mean we charge the battery and then goto sleep... if the charge is only 3 hours but we sleep more than 6 hours the different of 3 hours there would make a difference to the battery stats... where the stats would start to get hayway ..
yes, i do flashing frequently, i quickly got boring with just one rom
and yes, i charge my phone before sleep almost everyday, is that bad ?
right now (with miui rom) for example : when battery indicator show 39% after charhing 4 hours more, disconnect cable, i turn it off, i enter recovery (this weird, it boot in recovery, as i know, we only can enter recovery if we have above 50/60% battery, right?) so i wipe batterystat and reboot... voila.... its show 75% ???
how come ?
in some calibration apps say :
" Its not necessary but recommended to use phone until it shutdown it self, and recharge without a break start with phone off"
since i can't charge with phone off because of my incompatible wall charger adapter, so i never complete this above step. is it really needed to be done?

This is only partly correct.
The battery would be affected if the output voltage of a replacement charger was different from the stock charger, although it is more likely that the Streak's circuit board would blow a component or two. However, the battery will not be affected by the output amperage of a replacement charger. The only thing that will happen is the amount of time it takes to charge the battery will increase or decrease depending upon the amperage the adapter puts out.
For example, 4.0V, 2A is a bad thing. 6.0V, 2A is definitely a bad thing. Both can do damage to the battery because the voltage is what has changed. However, 5V 1A or 5V 3A won't hurt the battery at all since the only thing that changes is the amperage. As added protection against damage and/or battery explosions, there is a voltage control circuit inside the battery that not only monitors the individual cells that make up the battery but also can measure the incoming voltage. If the voltage is too low or too high, the battery will cut the charge circuit and prevent an explosion. The circuit doesn't measure the amperage because it doesn't need to, and thus the battery will happily charge at both lower and higher amperage than recommended without damage.

thanks for explaining, so its okay right if i use 5.0V 700mA ?
Sent from my Amazon Kindle Fire using Tapatalk 2
It will work, but it will take longer to charge as it's only 700ma versus the Streak's 1A. The charger may become slightly warmer as it has to work longer, but otherwise you should be fine. Had the difference been greater, say using a 500ma charger when a 2A was required, you might damage the charger, but not the battery.
okay thanks, now i know how to charge my battery

Hello,
when the tablet was in the charger with 1000 mAh and my GF was playing plant vs zombies 2, it was not enough and was dead in 2 hours. So I put there the official charger 1500 mAh but then still it was not enough and was dead again.
Right now I tried to turn off the Location, Wi-Fi and she is playing. But is this normal??? Jesus you should be able to play with all the functions turned on and in the charger, not???
Edit: so it was emptied again even with everything off...
Edit2: i will try the origin cable because I used a different one

Did it show the charging icon while she was playing the game? I'm curious if it might be plugged but not recognizing that it should be drawing power from the charger...
Because charging cables are differently wired, you MUST either use the original cable or a cable which is definitely known to have the same wiring as the original one.

Differently wired how? I didn't realize there were wiring differences, please elaborate if you can, feel free to get technical.
I tried plugging my Z2 Tablet into a USB cable from a powered hub (computer off though), which I've used to charge my phone and my Kindle, and I know it wouldn't have much power, but it wouldn't charge at all, no charging icon, nothing. I've had no trouble charging it with a dedicated charger though.
~Troop
So yes,
1. the charging icon is there
2. I even logged the history and during playing the plant vs zombies 2, the power is oscilating around +- the same level but still going down slowly as a trend
3. I tried today to get the power back to 25% and now I am charging it. I have the battery widget where it shows getting mA about 390 to 890 maximum. But even it is the original charger, original cable and the charger is 1500 mA it seems that the maximum level is 890???
Can someone else try Batter monitor widget what they get from it???
Edit:
It sucks. It announced even today DURING charging from the original charger and cable that the charging is not strong enough. Wtf?
Edit2:
Here they say it is charged under 3 hours. Not my case :-/ http://www.digitalversus.com/tablet/sony-xperia-z2-tablet-p19609/test.html
Ha, that is really funny. I am from the Czech Republic and called the Sony support. They forwarded me to Xperia support. At Xperia support the girl said that she cannot provide me exact information because official release date here is 8th of April so she doesnt have the manuals etc.
Then my type is 511E3 which she again was absolutely no aware what is the type because I should have 621 or maybe 521 but not 511.
So I can try the support line next week with the question how many mA should go to the tablet during charging.
But what she said was also that the charging time could be up to 6:20. But more than 6 hours? Maybe it was about the Z1 model? And also told me that playing games with the charger will still result in draining the battery.
I need some other guys here who can test it with playing some games and check the mA during charging...
I don't have a Z2, but just wanted to mention that cnet saw the same (no charge while playing) in their review: "[..] the tablet lost power even when it was plugged in to the mains" http://www.cnet.com/products/sony-xperia-z2-tablet/2/.
I never experienced any of this. There's probably a problem with your unit.

And have you tried to charge it during heavy playing of some game? Which game, how long?
Can you test how much mA are you getting from the charger inside the tablet (battery monitor widget can do this)
I tried it yesterday playing "The Cave" for about 1 hour. Tablet was charging using a four port no name charger and a different cable the that the one provided.
I did not really check for anything , I just noticed the tablet got mildly hot.
I did not measure the current while playing, but I did earlier this week-end though.
I tested 3 chargers plus the provided one. A Galaxy S III charger, An ASUS TF300 and the 4-port no-name I used yesterday.
If I recall correctly I got around 0.9A from the GS3 and original charger and around 1.2A from the TF300 and 4-port ones.
I do some more thorough testing and let you know. I use a device on the charger output to measure how much current is coming through.
How long do you guys charge the tablet? I started with about 19% and to full 100% it was like 7-8 hours. It was turned on without wifi (stamina mode). I will try to charge it while turned off but still it is strange...
I dont know. Battery life is ok but the charging sucks for me. Any ideas if it is just me?

Yawn... Please use the charger and the cable which come with the device (which I bet my grandma on you didn't)! Other chargers or cable have either too low current or wrong wiring (which disables fast charging) or both.
The charging time over USB is 4-5 hours, like the first generation Tablet Z.
Yawn, yawn, if you took a look then you would read from this topic that I use original cable and original charger.
If the battery is 6600 mA and charger 1500 mA then the minimum for charging is 4,3 hours approximately. And as I said my maximum charging is 890 mA. So either something is taking 600 mA during the charging or the charger is bad or the cable is bad or I dont know.
But if it is in the stamina mode and still the maximum charging is 890 mA then something is weird.
I am asking now for about 5 times. Could somebody test during charging how many mA is going into the tablet? (You can use Battery Monitor Widget from google play).
Neither Xperia support is able to give me clear answer because the Tablet was not officially released here (which is funny, I have it).
Thank you.

Dude, then simply go and exchange the charger if it is faulty. No need to make long XDA threads out of that.

Its not about charger. Or maybe it is. I want to know exactly how many mA are going to the tablet during charging. Nobody was able to give me the answer.It could be faulty charger, faulty cable, messy apps in the tablet (which I doubt) or whatever.
And Sony support, Xperia support is not able to give me clear answer to this. And also another guy in a review had similar problem. If we are in a Z2 Tablet topic then I supose that this is the right place to ask such questions... Not?
You can't just do 6600 divided by 1500. You are losing current all over the place when charging. It will probably be at least 50% wastage in heat, resistance in the wires etc etc. Also, the charger may say it does 1500, but that is peak when it's brand new under perfect conditions and the internal components will age and become less efficient over time too.
If you are using the tablet for a game, it will be running the processor at max power and drawing lots of current and all the heat it generates from the cpu and the battery during this time is wasted energy don't forget. If you want to battery to charge, you will need a charger that provides enough current to power the tablet and another 1000ma or so on top of that to charge your battery.
I bet Sony will state somewhere that you can only use it for low power activities like watching videos while on the dock if you want the battery to charge.

My portable power meter seems broken so I cannot give you actual current draw measured in series. All I can do is paste output from Battery Monitor Widget.
All tests done with the official USB cable bundled with the tablet and screen ON at minimum brightness. Screenshots from Battery Monitor Widget.
Code:
Battery only: -721 mA (-10.79%/h)
Official charger (1500mAh): +719 mA (+10.76%/h)
PC USB3 port: -48 mA ( -0.71%/h)
No-name Chinese AndroidPC Charger
Model LA-520 (2000mAh): +1060 mA (+15.86%/h)
Energy Sistem K128 Charger (2100mAh): +960 mA (+14.37%/h)

Thanks a lot!
So it just means that in general with the original charger you are able to get to 10-13% per hour. So in average usage 9 hours of charging, heh. I saw yesterday (have to check it at home) that I had also around 20% per hour.
But in general these figures are normal and the usage of a battery with a little bit more heavy tasks is not very good. And charging can take a LONG time. I tried to charge it while turned off and I think you can get there below 6 hours.

mm.after read all of reply above, it is quite weird that only get 800mah while using 1500mah support charging cable? Maybe can try better quality of cable and also the power source, it is very crucial to get that. I have try some trial and error with different cables and charging with my galaxy s3, i find that with good quality of cable, i managed to get 1000mah max , but if using with cheap cable or power bank, i only managed to get 400-800mah. even after a long time using the original s3 cable, it will reduce to only 600mah. So my advice is try charging with different cable and find the best cable to charge ur device, if it is 1500mah supported, so i think it should be support to 1500mah. Thank you.

No, it is not weird at all since the tests were done with the screen turned ON, draining half the power.
The first line, battery only, tells you how much the screen and semi idle state is draining, with brightness at minimum. Cranking brightness up to maximum increased an extra 2.5% per hour drain if I recall correctly.
Charging with screen off would be about 20% per hour, or 5 hours to fully recharge. More or less in line with what people is reporting.
Code:
Battery only: -721 mA (-10.79%/h)
Official charger (1500mAh): +719 mA (+10.76%/h)
So, 721+719= 1440 (+21%/h), pretty close to the rated 1500 for the charger.
I have an Infinix Note 2 (X600)that have some charging issues
when i charge the phone i usually need to jiggle the cable a little bit to get the power flowing, but lately it gets much worse. when charging my phone need a lot of time to charge. The charger is not the original phone charger, it's a spare samsung charger i found lying around in the house. its usually works fine up until now. I checked the charging power in ampere app and i found that the charger lose charging power slowly over time. for example the initial charge rate is 900ma , the charge rate slowly decaying -10ma /5-10 second to a point where the charge rate hit 0ma. i could leave the phone overnight but instead of charging the phone it reduce the phone battery instead.
My initial thought that it's because the faulty charging port because i game while charging and janked it fairly often. and ideas of what causes my problem or a fix ?
second question: is charging ports of micro usb android is all the same ? or it's different per phone model, cus im thinking to get the port replaced
Long story short. Use the manufacturer recommend,if not the original.
Yes they will mostly work, but when you take the cost of the device into account....
There should be information on this within the website for the smartphone etc.
Ironically enough, my battery died while I was typing this and I was running a GSAM bat test using always the original charger.
In logics term's, you can always start a car with a much cheaper battery, but when you're taking into account of longevity over quality and anything else you can throw at it, all roads have intersections...
Please email the manufacturer, things not the 90s so you will get better support [emoji12]
