hey everyone , i am having a problem my first recharge session for the xperia when the batter was fully drained was about 9 hours? is this normal ? for the first couple of times , i am recharging my phone through the usb cable from my computer directly ?
Please Advise
I've never charged mine through my computer, only synced. I will say it took very long to charge at first. I'd recommend using the wall charger and charging every night instead of letting it drain all the way.
Wall charger is the best choice, unless u have got a battery charger & patience to take off & put on the battery cover every time.
I doubt whether it is necessary to charge x1 every night?
I also find that using a wall charger gives a much quicker charge time and to my eyes a longer lasting charge... I only charge when it gets down to 20-40% so it could last as long as 4 days... (usually 2)
wallcharger takes about 2 hours till its full.
USB however takes far longer. not sure why but i guess the ma/h used for USB is probably far lower then a wallcharger
Yes, USB charging is slower than normal charging as the USB port can provide max 500 mAh, my old K800i on usb charging can arrive max 92% even after 6 hours connected, while on wall charging it is full in less than 2 hours.
And regarding this question, i have another question:
Will usb charging work with any usb wall charger? i leave the wall charger at home, and at work i use USB charging, but a co-worker has a motorola phone with a wall USB charging charger, can i use it safely on my Xperia?

Yes, if you check that Motorola output parameters are the same of our SE wall charger.
Thanks
Guys i did charge it from the wall charger and it took less then an hour to charge the remaining 50% which is great guessing so its going to take around 2 hours to full charge it from zero , , thanks for the help
I've got a split cable (two usb ports into one) that came with a portable USB HDD. It works faster when charging off USB.
also if you want faster charge time then make sure the X1 is switched off completely.
recharging ... Saving the battery
what i understand the the slower you charge the battery the longer the battery life ;it could stay with you for more then a year with good battery life
on the other hand quick charging the battery will decrease the overall age of battery you are going to change it with in a year or two
i am not sure of this info for cellphone batteries but 100% sure regarding the laptop lithium batteries
please correct me if i am wrong

As far as I know, the asnwer is yes for the first part. The slower the charging time, the longer the battery will last (theorically).
But, the time horizon is not 1-2 years. It is actually longer than that, 2-3 years for cellphones and 4-5 for laptop (own an HP from June 2005, still getting 3h of battery life out of it!).
There are lots of conditions that affect the life of a battery, check out at http://www.batteryuniversity.com/ for more info (that's a real useful site, up to me!)

Hmmm... great idea man... but I am wondering if it could affect the battery. Which is the total mah supplied?! is it less than the wall charger one? that info could definitively chamge my mind about the split cable
1) USB charge is way slower
2) Wall is about 2 -3 hrs
3) GSM plus average usage, 1.5 days of use
4) 3G plus average usage 1 days
what my laptop battery care program does to prolong live is that it maintains a max 80% charge. perhaps this is same for all battery?
[email protected] thanks for the update , tell me what your going to do .. fast charge or slow charge?

Sincerely, it doesn't matter for me. 4 year is way too long and I never had a phone for that period, so I really do not care about it. The only thing I pay attention is to always fully charge and discharge the battery, every time.
Consider that the first bound to a battery life is its recharge cycles. Probably 90% of batteries dies/loose power because of too many charge/discharge cycles, the 10% left for other reasons (fast charge, totally drained power, heat, etc.)

the website doesn't say much about Lithium-Polymer batteries as opposed to Lithium-Ion which is all over the site. Li-Poly is what Xperia is using. I think you shouldn't overheat the battery when charging because heat will drasticaly degrade the battery life.
Yeh
Yeh, as a note to some former replied.
Li-Po (Lithium Polymer) batteries need to be kept in check, overheating can make them dangerous and explosive as well as reducing their life cycle.
Which point you charge the battery from with Li-Po does not mattery as long as the correct "conditioning" cycles are completed when new.
Also, as a note, I have once or twice attempted to charge my Xperia from the USB port on my laptop(plugged in) over night, only to find the battery of the Xperia was totally dead the next morning.
The USB ports of my laptop provide 500mA (standard) and the charger for the Xperia is 700mA so not a significant difference, but I guess other things affect the the USB ports on laptop (including Windows 7 having the ability to disable US ports to "save power").
It most probably assume the "device" connected is wasting power and so disables it. Although we want it to charge. Same goes for Windows Vista. This option can be disabled though.

Yes, but wall charging while using connected wifi does heat the battery relatively quickly (my Polaris, Li ion, gets vaguely warm, not as obviously heated as the X1 battery)
I've tested this with a new replacement battery - careful overnight charging when new - and similar behaviour still results
This has convinced me that the X1 has a serious weakness, as charging while wifi connected is a long-standing work habit. If the wifi is connected without charging, a usable time of 2-3 hours is all you get (no good )
I've been experience that my battery life has improved ALOT when I charge it while it's on, also when I watch a movie or two and then charge it at the same time, when it reaches 100% I easly get more days out of it.
What's your experience?
This makes sense because the Wall charger has plenty of power to quickly charge the unit, while a USB connection is standard at 5 volts.
So the slower the charge, the longer it takes, the better it hold the charge longer.
In your situtation, you are watching movies while charging... which eats most of the power as it comes in, and supplies the battery with a slower charge; thus increasing the battery life until it drains again.
I do this with my Motorola cheap-o phone. If I power it via USB it'll last like 7 days... but if I charge it via a Wall Charger it'll be dead in 2.
Never really gave that any thought. You think the slower cycles going in, then the harder it is to go out? I'll keep mine playing movies while I'm sleeping then to get a better charge if that's true!
I thought that was very bad for the Batery, actually my laptop's batery is already dead (it drains full batery in less than 3 minutes) and I was using your method during all its live, around 1.5 years.
I noticed that if you use the Diamond during charge it warms up very much, compared to when not using it.
I must say that I noticed that some of the cicles where longer than others with similar or less use, I will test in the nexts days and post back.

ALL Devices like phones charge at a nominal 5v. It's the current that is different.
Wen you charge while the the phone is some way in use it works the battery to max efficiency and this results in a more efficient charge pattern.
Charge your phone whenever you can, never turn it off when charging and top up as often as possible. That will maximise battery life and max the potential capacity.
Don't discharge too low either.
Is this the definitive way to do it?
http://hemorrdroids.net/battery-calibration/
Those steps came from here, xda devs.
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6 **Root users only** Using a Terminal Emulator, type “su” enter, followed by “rm /data/system/batterystats.bin”
7. Run the device’s battery down until it turns itself off.
8 .Turn the device on and charge for at least 8 hours.
9. Unplug the device, turn off, then charge for another hour.
10. Unplug the device, turn on, wait 2 minutes.
11.Turn off again and charge for another hour.
12. Restart and use as normal.
Quite a performance! Does it preserve battery lifespan, or is it more to do with slowing down battery drain and does it really work?
He mentions 2 interesting things:
"Generally charge them before they get lower than 50%". I didn't know that, so it's actually better to charge more often and not let it drain down?
"USB charging is actually better for the battery and you may get up to 1 hours more standby time." So you gain an hour standby but it takes twice as long to charge the phone.
Nice manual
Will try it

Some will say that its complete nonsense .
Overcharge for 8 hours ??? how does the battery not turn charging off at 100%
Recharge 50% the accepted figure is not to go below 20% to often .
They may be right or wrong their are so many contrasting views on battery charging .

Discharging battery and then reloading it fully, it's the normal procedure for battery calibration for almost all the devices in the world (including computers, etc.).
Step 8 to 11 seems quite a bit strange however.
hm, just seen a different way to calibrate the battery. basically, you drain the battery, take it out for a couple of minutes, put back in, then try to turn it on to make sure it's completely flat.
then you charge it fully, then boot to recovery and wipe battery stats then drain and fully charge. so... which one is more likely to be the better?
that guy also advises to repeat that 12 step, 1-2 day long tedious procedure "every month or so".
it is lunacy honestly speaking
does it work? did he died ?
LOL I dont understand .... I just read in another day that NEVER LET BATTERY GO LOWER THAN 15% and know I read "drain drain drain" Oh welll ...
I also thought that at 100% the charging process stops.
Although this thread is about battery calibration, these questions about battery charging always pop up.
Battery calibration is the process by which you set your device with your battery data.
Every single battery is slightly different. Although there are minimum stantards to every spec of the battery, each battery is different.
Calibrating your battery is nothing more than setting your phone to the real specs of your own battery (since the phone comes configured with the battery factory standards). For example, your phone may be set to use a battery which maximum charge is 1650 mAh, but your battery has a maximum charge of 1625 mAh. That may be within the acceptable factory standard, meaning you have a normal battery, but that also means that your phone will never indicate a 100% charge after you unplug the charger.
If you calibrate that hypothetical battery, you will "tell" your phone that its maximum charge capacity is actually 1625 mAh, meaning from that on your phone's battery indicator will be more accurate.
For that reason, it is necessary to fully discharge and fully recharge your battery for the calibration process, since your device must read the actual specs (minimum charge, maximum charge, charging current, etc) of the installed battery.
I don't know about how many times this full cicle (discharging and recharging) must be performed, but that is the reason why it must be performed for the calibration to succed.
A DIFFERENT THING is the normal discharging and charging process during normal use of the phone.
In this case, you should NEVER let your battery go under 20% and, what few people know, it also should never go over 95%. This stresses the battery and diminish its life time.
Also, and there's a lot of doubts about this, the lower the charging voltage, the slower the charging process, but the longer the battery life.
High charging voltages (like the one used by the charger sold with the phone, which is around 5V) stress the battery, diminishing considerably its life time.
That is true for all lithium-ion batteries!
Therefore it is better to charge your phone through USB (which uses around 4,3V) than to do it using the charger provided with the phone.
You may be asking "If the charging voltage of the charger provided by the manufacturer stresses the battery, why does the manufacturer provide such charger?"
For purely commercial reasons! Higher voltages mean shorter charging cycles, which please the consummer. Moreover, the battery capacity loss with the factory provided charger is around 15-20% a year (considering "normal" to "heavy" use). That is to say that after a year your battery will only reach 80-85% of the maximum charge it used to reach when it was new. And by that time your manufacturer expects you to consider buying a new phone, with more features.
Summing it up:
- calibration is just the process by which you "tell" your phone what the real specs of your battery;
- in normal use, charging your phone through USB is better than doing it with the manufacturer provided charger;
- try not to let your battery charge go under 20% nor above 95%;

Spin three times in clockwise direction with left middle finger on your nose while blinking your eyes with the phone plugged in.
Jump in the air 3 times.
Unplug phone.
Thats some messed up instructions.
Do you have any idea what kind of strain you're putting on the battery while doing all that?
All you're gonna get is some extra minutes, maybe an hour but is it really worth it because you're just reducing overall battery lifespan by doing that procedure over and over.
Specially when you constantly keep the battery at 4200mV (full charge) for a long time. You're practically killing it by overcharging.

Never done a calibration on a battery and most of the time i even didn't let battery to discarge very much and then load it again. Never had a problem with battery life it last how long it should last every time and i've used that battery for years. So the battery "calibration" are kinda useless.

You should post the source for your info, cause I am seeing a lot of incorrect information in here.
If you guys want to learn about your battery, visit the site Battery University
The OEM replacement battery is worth about $10.
Save yourself the stress....use it...charge it when you need to...if the battery ever fails cough up $10.

The way I would calibrate my batteries is a bit different. Lithium ion batteries don't need to be drained then charged to full AFAIK, and I even remember reading somewhere that draining it is actually only for NiCad batteries. It used to be relevant when phones were using NiCad but not anymore.
Read: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
As such I have read that the universal way to 'calibrate' batteries is by charging to full, using for a couple of mins and charging again.
What I have been doing is:
1. Charge to full when phone is switched off (doesn't matter if it's from 0% or 99%).
2. Switch on the phone, use for 5 mins.
3. Switch off then charge until full.
4. Repeat step 2 once more
That's it! It seems pretty simple but it seems to have worked for me.
The way i do it is different. Firstly i have the battery calibration app from the market by Nema..then i fully charge my phone and when it says its fully charge i go into the app. There it gives me the instructions on how to calibrate...First i wait till i charge the phone without any interruptions. then click on the app and wait til the battery goes to 4200MV and then i press the calibrate button and then the app does it for me. Then i drain the battery again without any interuptions or breaks during that time and then charge it again once battery dies down and thats it.
there are so many ways being touted on the forums you really dont know which one to go for...but whatever works for each person then who are we to tell someone different just thought i share that
If my battery dies, or gets significally lower capacity after 1 or 2 years of usage, I'll just buy a new one if I plan to keep the phone longer.. Going through these rituals and painstakenly monitor my battery % so that it never goes below 20 % or above 95 % is just not worth it.. Doesn't increase the life THAT much anyway.. I use the phone until I hear the beep for low batt, and from there until I have a charger available.. Most of the time it's before it reaches 10 %, thats good enough for me.. Once in a while it might even go so far that it dies.. Then I charge it till it says 100 %.. Most of the times I plug it when going to bed, and let it charge over night.. This is normal usage and what the battery should be designed to handle, and so far it does..
To full chagne the battery, need more than 10 hours. Tried different ROMs, Batteries, changers, cables. the same result.
It looks like a hardware issue...... but....
when I used a DC power supplier(5.2V, limit to 1A) and plug in the cable, it appears the DC current is 0.5A, and after 10 second, fall down to 0.1A. at least, in the first 10secend the hardware worked all right...

I was quite surprised when I switched to the Note from the Dell Steak. My old phone would charge much quicker. The Note takes about six hours to fully charge I'd say. As a result I plug it in pretty much whenever I can.

Yeah, Mine can take around 5+ hours too if im charging it from <5%
Bear in mind that it is a bigger than normal battery, 2500mah.
But if it is like you say, Taking 10+hours to charge, Id get it looked at, Maybe send it off for repair or something.

Isn't it bad to constantly charge your phone even when it still has battery?
I heard it reduces the battery's life span.
I dont believe it is, I often charge mine even when its got plenty of juice left.
It may reduce life span, But the battery will live longer than the time you will own the phone so i guess it dont matter
No one can help. feel bad.
I saw sevral links saying same problem, but no solutions... poor us...

From what I've read, it's what you're supposed to do with the current generation of batteries. But then there's so much crap floating about about batteries it gets hard to figure out what is reliable info.
And this is with the original charger? If it's not an official charger, there's a big chance the phone will draw only what's usually allowed across USB. Which isn't much... In fact, with USB, the power draw of GPS/screen on/games can make your phone discharge even with the charger on. So try the official charger, on AC power.
Same problem...
I have the same problem.
At the beginning, about 3 months ago, my SGN works fine, battery are charged to 100% in 2 hours maximum.
I'm buy the phone from a Samsung Store, all accessories are originals. Today I send my phone to the technical assistance and there's no problem with battery or the charger.
My problem stars about 3 weeks, with an alert about different voltages after a full charge, the problem was solved only removing the battery and waiting an hour. At the technical assistance, the answer was to charge the phone when it's shutdown.
I already try that, format the cache, rebuild the system, everything using the ICS LQ3 from Baltic.

Is the problme solved after remove the battery for 1 hour?
paddyzou, the problem with the wrongs voltages, yes, my steps to solve this:
- Full discharge
- Shutdown of the phone
- Remove the battery for 1 hour
- Full charge with the phone hang out
The problem with the low charge I think that was okay, it's seen to be happen in random times, I just flash another LQ3(France) version of ICS yesterday and seems to be working fine.

This is correct, a chemical reaction takes place while the battery is discharging and is reversed when charging(changing). The chemistry of the battery changes how they hold energy. The Lithium ion batteries in our phones can be charged any time, they have no "memory" characteristics like previous rechargeable batteries (NiCd).
OP, it sounds like your charger is going. My stock HTC charger (2-3 years old) now only charges at about 40% the speed, which means the phone will discharge while its plugged in. I recommend grabbing one of those tiny square usb chargers (1A 5v, not 0.5A). I got one for like $6, as long as its 1A it will be quick.
Hello,
I am doing an experiment since few days ago. I noticed that if you disable the Fast Charging, and (most importantly) use a proper, thick 2A USB cable (I use a Kindle Fire original cable) then the battery lasts around 15-20% longer.
How to recognize that you got a proper USB charging cable ? With fast charging disabled and the battery empty, the phone should tell you that there are around 2 hours until full (instead of the usual 7 hours or so with fast charging disabled). That's when you know that you are using the proper cable. I bought a original Kindle Fire cable from Amazon and that is very solid, much thicker than the standard cable. See attached screenshot. With the standard cable this seems to be a hit and miss, you sometimes get the 2 hours message and sometimes the 7 hours message.
I repeated the experiment 3 times and each time I got significantly better battery life than before.
You may want to try it to see if it works for you.
PS: Attached is my latest battery life screenshot (APC8 firmware), which is the third charge since the experiment. 2 days 6 hours of stand-by with 5h SOT on a mix of 80% Wi-Fi, 20% 4G with nothing disabled (even Bluetooth is permanently connected to the LG smartwatch). Almost no videos played, only web page browsing which is quite demanding on battery.
Look if new software update is possible.
Yeah, I noticed that my battery life was worse when I used a ****ty 1 Ah Sony charger when I displaced the original Samsung charger. It took about 3 hours to charge it up to 100%, but then I noticed that the battery life would be worse than before. I found the original charger again, and battery life is back to being good again. I never use fast charging, unless it's in the middle of the day and I'm heading out or something.
None of the things mentioned above should (technically) have any impact on battery life once unplugged? I mean, stored electricity is stored electricity, so if someone QUALIFIED could give an explanation here, it would be cool.
Nothing new, I've always noticed that if I charge the phone with the original charger and fast charging disabled it will last much longer.

This cable? Which AC adapter do you use?
None of this solutions should impact battery life Oo. Energy is energy, no matter where it comes from?!
Would be nice, if someone qualified could tell us more..
Do you have the newest android version installed?
By the way, I only charge with original charger and cable, fast charge disabled (battery life is longer?!)
Battery life depends on how well you follow charging & discharging cycle. I usually fully discharge my battery (so that phone will shut down by itself after dropping below 1% charging), then charge it fully keeping it switched off & then use it.
I always had far better battery life than most people complain about.
BTW, I also tried charging battery keeping phone switched on at 10-15% charge remaining, battery definitely performed weaker for my use.
So that confirmed my theory based on my usage over last 7 years..

Yes, this is the exact cable I am using. A bit expensive, but for me it was the only cable that consistently worked at 2A over time.

I wonder if Qnovo is qualified enough ? Their technology is employed in many charging solutions. Here is what they say:
"Add fast charging - it gets noticeably worse. It turns out that the simple way batteries are charged today causes most of the damage that leads to shorter daily battery life and reduced lifespan."

So you're saying that Kindle Fire cable extends battery life? Isn't 100% battery life from one cable the same as 100% battery life from another cable? Energy is energy.

In no way I am saying this. I am just saying that you need a cable that reliably supports 2A charging, so the charger shows 2 hours to full instead of 7 hours to full, even with fast charging off.

Ah okay. I went ahead and bought one!
It ' also the logical thing. With fast charging , the battery holds less charge than the "normal . " He just spoke in various forums of this.
Anyway , great idea.
How to maintain max battery life span (reliable source):
Perform shallow discharges. Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
·Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.
·Fully discharge it once a month. This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

But you stated that it increases battery life.

What he's saying is that a slower charge equals a longer lasting battery between charges.
But maybe that doesn't apply to Li-ion batteries, according to this link here.

You can try it for yourself (if you have an S7/Edge) and report the results here. I posted my results, I'm not an expert, I just tried this. I also tried the 7-hour slow charge (with a different charger) and it didn't work as well as the 2-hour charge. The 2 hour charge seems to work best.
Yeah, If you use fast charging the battery dies a little bit quicker. I recommend fast charging if you are in hurry.
I only use fast charge when I'm in hurry.. Nice feature! I try to charge my phone between 25-80%...

Worst thing you can do for the lifespan of an Li battery.

I disagree, even though it switches off itself, it still has charge, don't go by it says 1%.. so it's not fully discharged... besides my method served a good battery life to me over the years with earlier phone models
