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.)

Yes, I use my old Motorola V3i charger to charge the Xperia, no problems.

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 )
Helllo guys, i just bought the nexus 4 and i want to know some information about the charger that can extend battery lifetime of our phone.
the first question i have is if the use of another charger (f.e. my old samsung microusb charger not an oem kind from ebay) with different voltage an lower amp output is there any damage to the battery?? i know the when the phone charge up to a point, it sends a signal to the charger and lower the output, so if the charger is not the nexus 4 charger could it affect the battery life time? is it preferable to use an older lg (not nexus 4) charger than a samsung or sony charger?
the second question i want to know is if there is any problem leaving the phone on charger all night. a charge cycle is about 3 hours but is it good to charge it for 7-8 hours??? i know the best approach to maximize your battery lifetime is to charge it up to 80% every time but is overcharging damaging for the battery lifetime?
the third question i have is why the phone is charging MUCH slower when i change the lg microusb cable with another?(i confirmed that with the two others micro usb cables that i have the phone recognize the charger as usb not ac charging). if it's the cable's fault, what cable i must buy not to have this effect?
i am asking this questions because i know the battery cannot be change by me without void the guaranty, and google didn't help me answer all my questions
1) slow charging won't damage the battery, but instead it will give it more battery lifetime
2) there's no such thing as overcharge becaude android cuts the charger at 100% and then accepts charge when the battery gets to 98%, so it keeps bouncing between 100 and 98, nothing bad will happen
3) slow chargers make this problem and if you're using the phone while slow charging it won't charge, it will drain the battery, but slower than not plugged in. it can be either from the slow charger, or the cable. try using a 1.2A+ charger, and don't use an extension cable, the smaller the cable is, the better

I received the Verizon quick charge bundle yesterday. Quite a deal for the battery, the car charger and the new slanted Samsung wireless charger. It seems like the wireless charger is pretty snappy, but with no replaceable battery, what will using it do to the long term battery life of the S7E?
Is it OK to use it whenever? Like frequently putting the phone on the stand to get it from 90 to 100%? Or leaving it on the stand all day or all night? Any tips on how the wireless quick-charging technology works and its effect on battery life would be much appreciated. Thanks.
I don't remember exactly which thread but someone mentioned that fast charging would also negatively affect the battery over time due to killing the battery cells. Might be in the battery life thread..I slow charge mine overnight and only fast charge using my car charger.

maybe thats why even sammys fast changer is not very powerful??..
Hello, after sending my s7 edge to warranty for terrible battery (2h Sot at the top after a clean install), i´m questioning if could be the use of wireless charging every night the cause of so fast battery degradation.
In battery health concerned, there is a difference using the wireless charger instead of normal cable charger?
And btw, a good Samsung wireless charger is better than a ordinary one?
I would also like information on this. I have used only wireless charging non samsung charger fast charging disabled in settings. My phone is almost a year old and it out still working well. Just curious about best practice for battery health longevity.

Yes, I'm also have quick charge disabled.
So, what kind of wireless charging? Regular QI, or the newer Fast Wireless chargers? The answer depends on that.
Batteries don't like heat. Batteries heat up when they are charged and discharged because of internal resistance. All those electrons flowing through the battery generate heat. The question is how much is too much.
Rapid charging (like QC 2.0 or 3.0) puts more power into the battery than normal slow charging. More power means more heat. And the closer to full charge the battery is, the more heat is generated. That's why all the rapid charge systems reduce the charging voltage and current as the battery "fills up."
Does wireless charging heat up the battery? For regular "slow" wireless charging, the answer is maybe, maybe not, but probably not enough to notice in any case. There are two things going on with wireless charging. The first is the wireless coils in the charger and phone, the second is the amount of power flowing into the battery. When charging, the coils generate heat. With a well designed phone and charger not a lot, but some. IF the coil gets hot enough, and is close enough to the battery, to heat up the battery, then it could have an effect on battery life. But the output of the wireless coil to the battery is not that great, so the battery won't heat up from the charging itself. Using a standard wireless charger on my Edge, the phone barely gets warm, so I'm not worried about damaging the battery.
With a rapid wireless charger, though, the answer may be different. Samsung's rapid wireless charger puts out enough heat that Samsung put a fan in it. How much of that heat reaches the battery I don't know. But since it's a rapid charger, it's pushing more power into the battery, which WILL make it hotter than a slow charger. So just like a wired rapid charger, it probably does have some impact on battery life
tl;dr version: If you're using a standard (not rapid) wireless charger, don't worry about it. If you're using any kind of rapid charger, only use the rapid charge mode when you really need to.

That's my opinion too.
The fact is that I'm using a regular/slow wireless charger and my S7 Edge barely gets warm at charging. But even so, my battery must have a problem ( I'm waiting for Samsung report). If it proves that wireless charging it's worse for battery (and it's just one year old), I'll switch to the good old usb cable.

I recommend to read this
:good:
They replaced my battery, now its much better.
For now, I'll try using only the provided charger and cable.
is it safe to leave the device on the wireless charger after 100% charge level? i have the same question for wired fast charging.
wired charging is no problem, since it stops to charge when it's full. even if it shows 100% it's not, because it loses a bit when it's fully charged for a while.
when i use wireless charging over night, my phone is warm or even hot every morning. batteries don't like heat, so i asume it will be damaged after some time.
Do you guys have the same experience with wireless charging? (I'm only using original samsung chargers with my exynos s8)
On my note5 (S8 arrives today). Over night wireless charging did not result in warm phone in morning. Could be because I purposely bought the slow or regular charge cheotech charger

even i have the non-fast charge wireless charger.
I only charge my phone once a day which is when I go to bed, but I turned fast charging off since I don't need it to fast charge overnight. With the previous Samsung wireless charging pad, I'd wake up to a warm phone in the morning (I've just been having problems with the older versions in general). Finally bought the new convertible charger since it was on sale, and I no longer wake up to a warm phone.
I have a none fast charge pad and use it overnight. No warm phone in the morning and battery capacity isn't decreasing very much at all according the Accubattery.
