I bought a m4 aqua today, but facing some problems - Sony Xperia M4 Aqua

Well, today i bought m4 aqua, and i'm facing some charging problems
this didn't happen with my old smartphone Xperia miro.
1. tried to charge it when it was low on battery like 0% but it wasn't even charging i don't know why, had to plug USB to my PC to start charging it.
2. Takes too much time to charge? It currently says 8 hours until the maximum charge, what the hell? My old smartphone only took like 2-3 hours to get to the maximum
battery
3. Kinda disappointed when i was supposed to get 8GB internal storage, and i only have 1.7GB, i cleaned some stuff and now i have 2.3GB
My warranty gets void because of this?
Is there a way i can fix this?

The device has exceptional little storage, that's s a fact, sorry to say.
Did you root the device in order to clean the apps you are talking about then you might have voided your warranty yes.

Also it heats a lot, with almost nothing opened.

I didn't root it, i simply cleaned some files.
and moved them to my SD card.
What about the charging?
it takes a lot to charge it to 100% imo
6-7 hours it says.

If you only removed some apps then you haven't voided anything. And if your device won't charge appropriately using the stock charger then your device is defected.
Restore it to stock in Settings and get a refund.

It's not that it isn't charging appropriately, it is just taking too long
compared to my old smartphone Xperia miro
also, will it get voided if i restore it to factory settings?

Also the USB won't charge the phone at all, is this normal?

2400 mAh battery will charge in aprox. 3 hours with USB from Sony stock charger and 5 hours with USB from PC.

I don't get it why is it taking more than 5 hours then.
also I notice a burning smell coming from the charger after a while
is this normal?

Don't let your battery go under 20% limit since this dramatically shortens battery's life.
While charging, use Sony or Sony Ericsson branded Greenheart wall-charger. Not using Xperia device while charging will get you faster charging times.
It shouldn't take more than 3 hours while on idle. If Xperia device is turned off or in Ultra Stamina mode, charging will take about/less than 2 hours.
If it still says and happens charging in 7-8 hours, send your phone to the Services.

Just charged it in stamina mode and it took so much less time, thanks for help
but, now i notice a burning smell coming from the wall charger, is this normal?

That seems like it isn't normal. I think that maybe wall charger is defected.

Smoke smell isn't OK. It shouldn't be burning or smelling. You should change your wall-charger.

Xperia S not charging

so i bought yesterday my Xperia S, im pretty happy bla bla bla...
Now, my phone was branded with a carrier [Telcel] from México, so I found a tutorial to unbranding, flashing with flashtool a generic UK firmware....
First was charging normally, but after that the phone dont charge, i left it all the night and only gets to 50%, and now im putting bacj to the charger and its getting 1% - 4% and then go back to 1%, so anybody knows why happens this? how to solve it?
Thanks
Maybe your phone is a faulty one ? contact the carrier, they will most likely replace it with a new one
Does it charge offline??
Press volume up +power untill you feel 3 vibration that will reset and turn it off then try to charge again.
If you succeed to charge it you will have to flash another firmware.

Before flashing, do a factory reset. But I suggest you to contact the carrier
Well after all your recomendations, i do the power + volume combination technique, and a factory reset (now with Pc companion...), and the battery start to charge, now in 4 hours I get 80% LOL but i think that its discharging a little quick, in 4 hours unplugged battery is now 40% (and im not doing anything with the cellphone...) so tomorrow will go to the service and see what they can do... I hope they give me a new one ¬¬
Hey friend ok i register at xda forum only for your issue
Ok look. Before year i buy my X10i it was and it is "the perfect device for its age". I had issue with battery like you. I did research here and there and ... I solve it with doing the following.
Charge the device to its max (until stop charging). Once is charged don't unplug the charge and remove the battery. wait 10sec and put it again. You will see that device will start charging again. Do that like 3-4 times for next 2-4 days and you will see improvement (at me).
From beginning my device battery was fully discharged in 15hours standby now it keep 2~3days .
Wish that help you a bit.

Ohhh thanks for only register for that , well tonight i charge the device all noght again and it get 100% of the battery , the problem here is that in the Xperia S you cant remove the battery , right now im charging again and its a little annoying because the battery goes 1%... 2%..... 1%..... now its like 3% but it goes too slow......
I read that this device in half hour have to be charged almost to 100% isnt it???, because i think that 30 minutes i will get only 10% or something like that ¬¬, i was trying not to go to the technical service but i think that i will have to go

Yes i have another sony ericsson (mini pro sk17a) and its the same charger.... the same situation, even tieh another cable and in the laptop... the same
Soooooooooo continue with this sadness story... i go on tuesday afternoon to give the cellphone in the service center and they told me that they need to check it, so I say ok ok no problem, I go on Wednesday in the evening and they told me that the cellphone was without failure, that its charging and its ok, they told me that "upgrade" the system version (that its not true... its the same ¬¬) and well.... that be all, I made a question ... How many time take the phone to reach 80% (they are giving me with that charge) ???? and they told me: (with a face of surprise ) like 2 hours.... and I say: It's too much isn't it?, and the women said me that for this type of phones is normal..... so i want to make a question for you... how many time take your Xperia S to charge??? since 5~10% to 100%???? for me 2 hours to get 80% its a lot of time.....
Accordign to the respondes in here i will valorate to go again or leave it in that way....
BTW the cellphone its now charging but its too slowwww for me.... I plugged it at 12:30 am and still have 30% of battery, 40 minutes later its 47%....
How are you charging?
- Via USB or via power charger?
- Is Phone turned on?
- What temperature is the Phone? can be be hot? If it is hot the charging might be slower due to battery protection.
- Aren't there anything consuming battery? What do you see as main contributors in the Battery usage?
Well sorry for take a time to respond but i wanna try and wait a couple of weeks to come back XD

- I have try both of them, via USB take a loooot to charge, and if I start to play even it starts to discharge.... x_X via power charger if im playig with it charges too slow... but charges, it takes 2 - 3 hours to get 100%, if I turn off the screen charges faster, but if i received a message or something the screen turns on and besides the brightness is almost minimal it seems that take more time to charge.....
- Yes its turned on, when its off it seems to charge faster but... well i'm off like 2 hours for all my friends or family
- Its cold indeed, right now its charging and its cold, not heat at all
- The main contributors are:
the screen... obvisuly 56%
Android system 12%
cellphone in wait 12%
standby phone 6%
wifi 5%
facebook 3%
and mcafee 2%
as you can see nothing strange
I dont have brightness to 100% its like 30% when its on and only wifi turn on
So i want to ask again to you, how many time take your Xperia S to take 100% of charge??? its normal this behavior...?

For me, it takes two hours. That's without me using it during the charge period, wifi/data/bluetooth off.
One question: which charger do you have? EP800 or EP850/851?

2 hours well it seems to be "normal" then, i will have to turn all off and see how much time takes... for me its too much i get used to have my mini pro (sk17a) get charge in 1 hour 30 mins or even less with the screen turn on and wifi & bluetooth on too
I have EP800, seems that EP850 only its given in a few markets, México its not the case
Ok, go back to the service center... and buy the charger they used in your phone...

You said that service guys tested the phone and it is ok, and you tested the two chargers with another device, right?
If yes, change your charger cable with another one. Try to use brand new, they are not to expensive. And try to find some brand name cable like Samsung or Nokia.

I have 2 chargers, and 3 cables , one from my xperia mini, one that i bought from ebay (want to have one in the car for emergencies of a dead battery) and a new one that come with the S.... I'm using the one I bought and the xperia mini.... maybe thats the cause but i really doubt it...
Same issue on Xperia P
I have a similar issue on my new Xperia P since day 1. When I charge my phone using the charger, it charges upto 50% +/- 5%. It will not go beyond that even if the charger is connected for hours. If I charge it from a PC through USB it goes to 100% without any issues. Also, if I charge it through the charger with the phone turned OFF, it charges 100%. So this appears to be a software related issue and not something to do with the charger.
Any suggestions?
*My phone is currently on ICS. Though the issue existed even with GB.
Well, let it pass a week and lets see what happen, mine fixes by itself, now just take 1 hour and a half to charge it , but in the beginning was a pain in the ass

Charging issue

Did you guys notice the battery take too long for full charge? Especially charging while in use. It seems doesnt charge at all
Could anyone help me out? I was charging and surfing web the XTZ at the same time, but the battery even went down by 2 to 3% in 3 hours even though the tablet was charging. Is it common or should I exchange it?
Thanks
Is this with the charger and cable it came with? I am not having this problem but different chargers and cables can cause issues

Yea I had mine at 10%, put it in to charge. Come back home 6-7 hrs later and it's only at 44%?!?

Yes. I used the original charger and cable. When I let the screen on while charging, it seems like its just preventing the battery run down, instead of adding more charge. I guess I got a defective battery. When the screen off, it just take too long for full charge, like almost 9-10 hrs. I test the cable and charger with another device it seem working fine. How long it take for you to do full charge when screen of btw?

I don't know exactly how long. But charging and using the device at the same time is no problem and adds charge at an ok rate. I would guess that a total charge would take around 4 hours but it is a guess.

Have you tried Stamina mode while charging? I believe it shuts down some background processing while the tablet is asleep. Might help speed up charging.

I did some research and this is what I came up with...
-- the USB charging seems to be hard-limited to a maximum of 500mAh intake. This is consistent with the original USB specifications, although no one really adheres to those anymore anyways. Charging with 500mAh is bound to take a long time and presumable even light usage (screen-on + sufing) will prevent charging at all and still drain the battery or keep it at the same charge level. I consider this a quite major design fault and wonder why Sony did this - if they had any strong reasons (overheating near USB port due to the thin build and no heatsink properties of the material?) or if it can and will be adressed later on by software (I am not sure if that is the case...)
-- this also means that using different chargers (if they work at all, the Tablet seems to be picky and did not make use of two generic ones that were tried, only a HTC wallcharger was accepted next to the original Sony one) that put out more than those 500mAh will either not work or they will deliver just the 500mAh the USB port accepts as a maximum
-- however the charging cradle contacts will readily charge the tablet with up to 1500mAh
If one were to assume the worst of Sony one could say they probably limited the USB charging to a minimum to push the sales of their original chargers. On the other hand one can argue that SLOW charging is actually better for the battery longevity, so Sony could defend that move with that reasoning...

There is a thing that while playing "heavy" games and charging from usb connected to pc it even dicharges. If connect it to stock charger (1.5A) it manages to charge but very very slow. There are chargers for 3.1A or even 5A which will charge your device very quickly.

Have you actually tried one of those with success? If so what is yout exact serial number for the XTZ ? As I laid out in my post a little bit above yours the XTZ seems to not take more than 500mAh via USB even from any charger...

i just did check the charger ... its 1500 mAh output. But it surely doesnt charge with that so clearly usb is limiting it Oo. So clearly dock is a must not only no flaping cover but also faster charge. Anyone with dock can confirm that ?

I guess this how they boost the sale of their dock and avoid overheating..limit the USB output. They also sell the micro USB and charger on sony website. Dont know if it could make any difference.
I had my tablet plugged into my pc and while I was using it the battery actually went up a 1 or 2 percent. I got mine two days ago so maybe it's an early production issue?

I noticed that if I set the brightness to the minimum, I would be able to charge while screen on. If I set to max or somewhere middle, i would not. did it happen to you? if not I think my battery got issue then.
I believe mine was on auto brightness for that moment. I did notice that in the last two days, full brightness drains the battery A LOT. Within 2 hrs of screen time I was down to 55% battery

Just got mine XTZ and so happy with it, but same thing it take so long for charge it even with the wallplug.
I just notice, i have the XZ and if i use the cable directly on the phone it take a long time for charge it too. But if u use the dock my phone charge in less than one hour ( or maybe a little bit more), So i can guess is a usb limitation on the sony product (or maybe a marketing trap)
Sorry for my English.
In my case, since i've the Galaxy S4 ATT version, i use that wall charger i've not tried the one that comes with the tablet but the S4 charger is a 2A while the Tablet Z is 1.5, with the S4 one + stamina mode + auto brightness + special mode(only 1 core running under clocked to 1036Mhz, conservative governor) my tablet charges ultra fast from 10% to 50% in 1 hour and half or even less, also my standby time is up to 8 days at full battery.
If you have your tablet rooted and you want to use my special mode, just download CPU Adjuster from Play Store, give it root permissions, then create a screen off profile, 1 core, max 1036Mhz and that's it.

why should it be like that? We have a 6Amp battery in there and if it WOULD charge all the time with 500mAh max we would have a charging time of 12 hours. But if the battery reaches 80% charge charging will be much slower. That means if your statement would be true, we would have charging time of over 14-15 hours.
I charged mine in 6-7 hours. 6000/6=1000 so it´s normal for our 1,5 Amp charger.
Okay, tested it. Shorty story is, there is no difference between charging via dock and charging directly via USB port.
Long story:
- variation tested: SGP312 (WLAN 32GB)
- Battery percentage at start: 58%
- Charging time: 70 minutes
- Charger used - the one which came with the Tablet. The dock does not have a charger in either case, you have to use the Tablet one (which I do) or a 3rd party charger for it.
The only difference between the tests is that once the USB cable went directly into the Tablet and once the USB cable went into the dock.
Battery percentage after 70 Minutes with USB cable: 80%
Battery percentage after 70 Minutes with Dock: 81%
So basically, it got from 60 to 80% about ~1150mA / hour independently of the charging method.
As a sidenote, bringing it from 80% back to 58% took 28 minutes of playing a 1080p mkv at full display brightness,

The Mega charging/discharging issues..

I love my Mega. It is by far the best phone Ive ever had. But, the problems I have with the power usage and management on the device are a total nightmare.
1) The discharging nightmare:
The battery lasts NOTHING. Basically I get about 5 hours of use.. maximum.. no matter what I do.. and I have slimmed down to the ROM to having that NOTHING active.. I literally am left with active 6 services and I monitor CPU usage that is always near zero with NO apps hogging resources. From what I monitor on the device's battery usage, it's clearly always about 90% from the display! And yes, I dim the screen as much as I can of course, but usually not below 1/2way.. I hate screens too dim. However even just on standby with the screen off I still lose about 5% to 8% of battery an hour. Worse, even with the device Powered OFF, I still lose about 20% of battery a day. The ONLY way I have found out to control battery drain completely, is to take the battery out. That's it. Anyone else with similar symptoms and a fix or, is just that the stock battery totally sucks??? Also, any other off brand batteries are any better?.. (not the fat ones rated at much higher amps but that have an extra bulge.. that I don’t want)..
2) The charging nightmare:
This to me is the worse problem. It is bad enough how quickly this device issues battery, bit not nearly as bad as trying to charge efficiently again. I now have tried 3 different chargers/brands (and cables) to try fix the charging problem that is, it takes HOURS and HOURS to charge the battery. I am talking 5 to 6 hours to get it charged and if the screen is on and Im using the device it actually charges NOTHING at all and still keeps discharging (albeit much slower of course)... the fact is that the charging process is so pathetically slow that is less than real-time which means, with the device connected to power supply, the battery STILL drains if I try use it. This is absurd. However, mysteriously enough I have found ONE way that charges the phone super fast.. using a SONY External Power Pack (model CP-F1L) rated at 2200mAh. This is seems crazy because the power output of an external power pack should be much lower than the stock (and other Samsung) USB chargers.. but, it's what works.. the ONLY thing that works. And I have noticed that when connected to a USB Power charger, the Mega's Red LED light turn on faded.. however, when connected to the SONY External Power Pack, is bright red. Clearly more juice going in.. or something like that. Again, anyone else with similar symptoms and a fix the charging time, or, any good recommendation on a extra strong USB power adapter/charger that will make this thing at least charge faster?
Thanks in advance for the input and advice:silly:
Sounds like something is not letting your phone sleep or the battery is defective. Try putting CPU spy on it and let it set for a while. Then check to see if it is getting into deep sleep or if it is even stuck at a certain frequency.
There is an app on the playstore called Galaxy charging. Try it to see what rate it is charging. Though with the rate your phone discharges, the charger may only being supplying an amount just over the drain rate which is why it takes so long to charge.

Yes this is not normal, I get five hours screen time on fifteen hours usage.

Yep, something wrong there. I'm stock and this thing won't quit :good:
I would flash the stock rom back into your phone and see how the battery works then as this not normal as mentioned by other members as I am still on the stock rom but rooted only and I have great battery life.
That is were to start by flashing the stock rom and if no change then battery or maybe a hardware problem.
Did you have good battery life before you starting flashing with the phone or did this occur after the stock rom was removed and custom rom with stuff removed to gain performance?

You could try to remove the battery from the phone for about 5 secs and re-install and see it that helps as sometimes if you take the charger off as soon as it is done charging it might not show 100% at times when booting as I leave mine on for a bit longer and it seems to help..even though charge light is green..I leave it longer on.
If your phone is rooted get a app called battery calibrator from the google store as it is free and install it and just before you shut down the phone to charge wipe the battery stats with this app and then shutdown phone and fully charge and then see how the battery works after the battery stats wipe as that can usually help.

Thanks for the tip. Installed the app you recommend, now I understand better. With the stock Samsung USB charger I get 420 readings. With the other 2 chargers I get 500 and 540. However, with the Sony External Power Pack I get 1900!..no wonder it charges super fast with it! My question now is what's up with all the USB chargers I have? I even tried my old Galaxy Tab 7 charger (strongest rated charger I have) and still only feeds 480. This is all so bizarre. So, where to get a super strong charger for the Mega?
(sorry.. by whatever reason my reply got posted 4 times.. so strange. I try delete the first three but cant)..

Usually when this happens there is something wrong with the USB cable not necessarily the charger. Is the sony cable a USB type cable or a hard wired one? If it is USB type try using it with the other chargers and see what your results are.

Yes indeed I notice the Sony Power Pack cable is short and thick. The Samsung cable is long and thin. I get much higher charging power using the thick short cable. Maybe I need go shop for a proper longer/thicker cable.

I've certainly found the USB cable makes a big difference to the charging speed. I got a couple of 2m cables off Ebay and they're hopelessly slow, but the stock Samsung cable is fast. I just wish it was a bit longer!
I have the same issue
I have the Sprint Mega. Not refurbished and original factory state but I have horrific charge/discharge issues. Right now, my phone just got to 100% charge which I then unplugged the charge cable. Within 5 mins, I went from 100% to 96% and it is losing battery even quicker.
VeEuzUKY: It's been a while but do you still have this phone? Any updates? I should prob invest in a thicker USB cable like you've describe. It has the most charge rate.
I got my mega 6.3 last week. Since then it has said 100% charged... even when charging or dead. So I got a new battery thinking it was the battery but its obviously not and im not sure what it is that could be the problem. Im not sure if its crucial for my phone, if it can be fixed easily and cheaply, or if I need to return my phone to the place I bought it from.

[Q] First charge-when enough?

Hello, dear XDA people!
I got my Z Ultra today.
YEEEEEEEHHHHHHAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!
Sorry, had to do it..
Now, I come from Note 1....and I have a few questions...
one of them is about the first charge...
I tried to read as much as possible, but on the Sony website and the paper manual it says only how to regularly charge and that the green light means it is over 90 percent... AND it says that before first turning Z Ultra on, even though it comes with some charge in it already from the factory, the phone should be charged prior to first time power up...
Now, I did charge it, but it is only showing green light, and no percentage (Ultra is off, I haven't turned it on yet)...
How can I know it is charged fully?
I don't want to leave it plugged in too long, cause I read that batteries don't like that..
new charger
for new phone or smart phone ,first charge is 8 hour,ok

just fill it til full and detach it after full, no need to leave it for 8 hours. as per my experience, first charge will not retain battery level for long. it will come empty fast, This is normal, so just charge it again after drained for a while (maybe 50%) and it will be normal after that .

modern Lion batteries (lithium Ion batteries) don't have a memory. They can tend to think that they have a limit if you only charge it to say 80% all the time, but a full empty and then recharge will annul that. So there is no memory chip or anything.
So charge it to what ever you want..
Also FYI, the green LED turns on when it's reached 90%.
So no need to charge it until 8 hours?
Because i just buy Z Ultra. So raelly need to know for the first charge..
TQ

...just use it right out of the box. Newly sealed devices has about 45% battery life. And it was about what my device had when I unpacked it.
I did not charge it. I just went ahead and started using it until I needed to charge it.
I cannot quite remember if I rooted the device on my first cycle or if I charged it before I started.
I discovered that if you use a note 3 charger or tablet charger you phone charges faster obviously due to more amps.

the ZU will happily charge at 1800mA, I've not seen mine charge any faster than that, I'v not been brave enough to see if true fast charge will work

TQ. But what i mean is for the first time charge is it need to be 8 hours?

.........no you don't have to sit there with a timer and wait 8 hours on your first charge. The text refers as a "recommendation".
Your phone will not explode nor will it bend or void your warranty if you only charging it for 7 hours and 53 min or 3 hours the first time.

[Q] Really need to charge the battery of the device 30 minutes before turning it on?

I have this doubt since purchasing the Xperia Z!
As soon buy my Xperia Z2 and the store where I will buy it is difficult to leave the charging device 30 minutes before turning it on to test it!
As difficult as it was I let mine charge for an hour or so before I used it. Not sure if I needed to but was in work at the time so had a few things to keep me busy while charging

My phone had 62% battery when I recieved it. Probably my contractor that installed some apps and charged it. I didn't charge it untill it was empty.
I wonder what is the need to leave charging for 30 minutes before turning on the device for the first time since the other brands of devices do not need it!

Mine also came with 60% battery when I got it, I think its normal to keep a charge in the battery because it helps battery life.
I let mine drain right down that first day then I charged to 100% overnight.
I currently get to end of day with around 50-60% left
You should always charge them to full before first use. The charge that's in there is only a manufacturing charge, which is enough to keep the cells active.
Also, you shouldn't drain it completely. Lithium works best from around 30%-80% charge.

What I find strange is why other brands of devices do not have this rule??
Li-ion batteries don't need to be fully charged before first use. They don't suffer from "memory" like Ni-Cd. But it is true that for best life you should charge it between 20/30%- 80%. If you plan on storing the phone without use for a long time, best is to charge it to 50-60% (not 100%) and put it away.
Go use and enjoy your phones!
PS: A few laptop manufacturers (like Samsung) have an "extended battery life" mode that you can enable where the battery stops charging at 80%.

Not all devices may say it, but all should be charged before initial use.

You're right, they don't have the memory effect, but they do need charging before use. But yea, storing with at least 2/3rd charge is best.
BTW I sell batteries for a living, have done for 15 years.
Ok so is the correct answer yes, charge for 30mins or not necessary? Seems both sides of argument has support

As an electrical engineer I have to say: You should charge it before first use. 30 mins charge should be fine.
Well, it might be not so obvious for the battery in Z2, as it was manufactured not a long time ago, but it could end up in battery degradation, if the battery has been stored for a long period of time without usage.
Ok so with the Z2's being manufactured within the last month it probably isn't needed then

Well, it's hard to say. Precharging the phone won't hurt.
I charged my first z2 for half an hour, and my second one was up and getting flashed within ten mins. I actually found the second one to be better on battery. I do agree that if the phone has been sat dormant for a long while you should charge, but as these things have literally just been made it'll make zero difference.
