[Q] Recharging the Xperia S - Sony Xperia P, U, Sola, Go

Hey all,
Since there's no Q&A thread as of yet, I'll be posting my question here.
I'm sorry if this has been asked before, I have searched for it but couldn't find the answer.
My Xperia S just came in today, I started recharging the device when it hit around the 10%.
However, it's recharging so, so slow! Is it supposed to be this slow?
I thought the Xperia S was supposed to have fast charge capabilities?
If so, how do I charge it faster?
It's a Dutch unit btw.
Thanks in advance for any help!

I have a generic UK unit the first charge does take slightly longer. It took around 2.5 hrs after that I got from 1% to 100% in just under 2 hrs. You are not charging via your PC are you?

Nope, using the supplied charger and cable..
EDIT: Also, there seems to be some lag on the home screen and especially in the app drawer.. Anyone notice this?

There are 2 versions of chargers shipping with the XS, EP800 ( less power output ) and EP850 ( More power output )
check your charger to see if it is an EP800, i am pretty sure it will be. The 850 does its job much faster.
Another way Sony is "cheating" on us.... after i got my XS replaced twice in 1 week and already waiting on another replacement it just do not surprise me anymore that things like this happen with this device.
First Flagship from sony alone and it is already a catastrophe

Ah, you were absolutely right. Second charge was way faster.
I believe I just recharged 60% within 30 minutes.

Yep, it's an EP850. The first recharge takes ages, but the second recharge is pretty darn fast.
I don't have any problems as of yet with the XS, except for its laggy home screen.
Wonder if I'm the only one whose home screen is lagging..
What's up with yours?

I don't get screen lag I did take mcafee off my phone. Also any apps downloaded apps you are not using turn the service off.

is ep800 safer 4 battery? quicker charging = shorter battery life?
more mA -> more resistance -> more heat -> less battery cycles life?

Someone else may know this better, but, as far as I know, Xperia S have tech so it recharge faster without problems.

It's no safer than the 850.
The phone was made to withstand the 850 charger (one of the selling points actually was its charging). My phone (Tmobile NL) was shipped with the speed charger, but I'm noticing that after a few weeks the phone seems to be charging fast in general, on any charger...or maybe I am just imagining things?
I have an old BB charger that I use sometimes (I have chargers all around the house from old phones, i swear :/) and it seems to also charge it fast.
Edit: Also, on both chargers, my battery life is just as fantastic at night I charge my phone while I sleep though ( I don't get why you wouldn't charge your phone while you sleep?) so maybe my battery is more worn-in than a lot of people.

My phone is plugged into my " old " desire charger at home, which seams to charge faster than the default one , saying that , I also use my PC to charge ,so maybe the little top ups help + the charger at home .
It does last a while now, however we are running a powerful ( mini ) PC , so we cant expect too much !!

TP2 battery

Anyone know where I can buy a extra battery for the TP2? I have found a couple in the UK but would rather find a seller in the US.
Part# - BA S390
Is the part# listed above the correct battery for the TP2?
Mine actually says "RHOD160" on the back of it...
I found a 1500mah battery on ebay (item# 250445669999) with a "buy it now" for $8.95.
Anyone have any experience with this "replacement" battery. If so, how does it compare with the original battery which is 1500mah also?
****Update****
I also found this 1500mah battery on ebay (item # 270409538954) with a "buy it now" for $21.99

I stick with genuine batteries now as I had a bad experience with after market batteries. My TyTN2 has issues turning on, and randomly turns off - even after I put the genuine battery back in. It seems the after market battery did some permanent damage.
I recently received some 1500mah batteries for the TP2. I purchased 3 units. I have a friend that will test these batteries before I use it. I will use one for the office, home and the other one will be opened and my friend will inspect the board and cell of battery. He usually takes about a week to do these test so, I will give you a update next week, if possible.
I dont really have a problem with the battery life of the TP2. Its just in case I forget to charge it over the weekend, due to my drunken stupor. Its nice to have a backup battery at home or work.
maybe I'm the only one with short life battery problem on rhodium... but I have to complain... after 3 times I've charged ...the battery dies in the evening.
maybe I must be patience and maybe it will improve after some charging cicle...but for now I'm disappointed.
anybody've seen a better battery on market for TP2?
well... i been an iphone user for a long time..
well since the first gen came out...
almost 2 years ago..
i still own an iphone First Gen (2g)
and now i been with the TOuch Pro 2
for about 3 weeks..
i love the TP2...
i did a test.. a little one tho..
i live in NEw YOrk.. in the bronx
i had to go to the JFK airport
in train so it was arround 1 hour and 20 minutes
maybe the trip...
i charged both phones to 100percent...
i was listening to music the WHOLE TRIP with the Iphone
and the TP2 was Idle...
when i got there... my iphone still was 100...
the TP2 was about 91%....
another stuff that i know it drains a little my battery from the TP2
is beejive but i cant live without it, i been trying a lot of methods to
increase my battery, cant see it perform better..
TP2 fully charge in the morning and it dies before 7pm..
just Textin, and some phone calls ( about 3-5 calls )
no website .. if so maybe 1 website .. no emails no push anything...
no bluetooh no wifi...
i ordered an extra battery and a craddle i hope this helps me.
something i figured was that the charging is REALLY FASTTTT....
it can go out 20% in about 15-25minutes of charging
( wall plug ) ... dont try to charge from USB it will take u 200 hours LOL
when i first got it i always charged from usb and used to take me like 8 hours
even more to fully charge it.. but when i tried from the wall plug..is Amazing
how fast it charges..

so what are you saying ? that im just here makin

i was a big fan of APPLE.. now i really LOVE
my TP2.. and i dont have any reason to be saying
something that is not...
my iphone battery was still 100%...
if u dont believe me then go do it yourself man
im just saying.. the TP2 really have issues with its
battery...
Peace dude.
Not saying that your statement is false or deceiving, just that your iphone battery meter was lying to you.
Clearly the battery level can't be at 100% after 1 hr 20 min of use. The meter must only drop when the battery gets to a certain level. Kinda like when you fill your gas tank and the needle stays on full for the next 50Km.
You must have the 1% increment tweak installed. Notice how a couple of minutes after taking it off charge it drops to 99%. At least this is realistic aye enjoy your TP2.
I found the screen brightness was one of the biggest battery killers. Since I took it off auto adjust and set it to full brightness all the time, the life had significantly decreased.

I don't believe you.. I dare say that because I was a user of iPhone 3G.. battery is hopeless.. I SURELY didn't get that kind of situation.. My wife still has an iPhone 3G.. also can't replicate your kind of situation..
In anycase, I do not believe any mobile phone device, listening to music at >1hr can still be at 100%.. surely the battery reporting driver has gone haywire..
However I'm not saying TP2 doesn't have battery reporting issues. Infact most HTCs I use seem to report battery differently at times.. usually after a soft reset, it shows a different battery status.

yea.. i agree with you.. but i noticed something on the iphone,
if u charge the battery to 100% and keep it charging for at least 20-30 minutes.. it will last long in 100%.. i dont know if is that my battery meter was wrong or something, i guess so... i was just trying to tell
what happened to me.... i really love the TP2 i wish i could have more battery life tho...
I hv no problem with my TP2. The battery last me for almost 2 days with 1 overnight charge. I'm liking it

It's just about how you use the phone.
I normally get a bit more than 2 days out of one charge, but then I'm calling and writing, surfing and checking EMails every 30 minutes, youtubing and listening to music.
Now I went over my data plan so I disabled the Mail-checking and did not listen to music for a while. The battery now lasts for 3 days with already 60% left.
I would say, one week battery lifetime isn't much of a problem if you don't use the phone's functions in any matter

Anyone bought one of these? Seems cheap - but if it works...
Comparin iPhone 2G with TP2 is not an apple for apple comparison. First compare with the ipHone 3G (Remember how poeple complained their 3G was lasting really less than their 2G and were switching from 3G to 2G to spare battery life ?)
Besides as many underlined the battery meter from iPhone is decieving (The TP2 has issues but less I believe)
In the end my TP2 last rougly 136 hours an I am quite a hevay user. Even if the iPhone last longer (I dont have an iPhone so cant compare both feelings, and my previous remarks come from my friends' experince who own one), the nice point with the TP2 is to be able to replace the battery with another one
wu dudes, well,my tp2 comes in 7 days.... i'll test it and than post here about life batery.... and freeway4you maybe u charge your batery when its not 0%. if you do that the batery is gonna be weak. sorry the english...

Yea i've had that same exact problem today, charged it, went to sleep and i woke up it was almost empty. I went back to the shop and replaced it, i'll see what happens now. Although after doing some research I think that it has to take some cycles to reach full capacity. Good luck bro ...

Is there an extended battery for the mini pro?

Despite all the tricks to help preserve battery, I still find the performance of y standard 930 mAh battery very bad. Is there an extended (reliabl) battery for rhis phone and where can I get it?
Just gonna drop my experience in. It seems the battery lasts for about a day and a half. Which can be seen as over three days (depends what time you charge it on the first day) instead of using the normal homescreen, download helix launcher from the market, it helps alot
Sent from my U20i using XDA App
One day and a half compared to my brothers Samsung's week is really a disgrace.
I already have another home screen, just got to like it, so not changing it at the moment.
I have contacted Seidio as they make extended batterys for other phones. Would not hurt if oter people did that too, so please, those who care about this problem, contact them and ask them.
I bought on e-bay a 1450mAh battery made by Jin Dian. A drastic improvement.
Didi anybody else try this? I got it but I'm not convinced it's better.
Seeing you all really hungry for power, it's just feel right to warn you guys. Never ever use cheap small portable charger that you spot either on a shop or ebay no matter how desperate you are. If you use it, best scenario, it only ruin your battery, or in the worse (like me) it ruin the phone. Both case has the same end result, the battery discharging way to quickly even when Idle.
How did it ruin your phone?
I would like to know. thanks
As I'm a long distance cyclist, I already own the Biologic ReeCharge. Anything that can be charged by usb can also be charged by that tool. I can use both my bicycle dynomo hub and the electricity network at home to charge the ReeCharge. Witch then is able to charge my phone. It's a kind of extra battery. Never have had any problems with that and I'm always glad on a cycle trip that I can keep my gadgets (most important gps) charged

Well, I don't know the technical details but it fried my batteries (that's right, more than one) before I realized it was the portable charger that caused and even after stop using it, it's still recurring (therefore, the phone is at fault) After asking my friend who used the same type charger once. They all said that it ruined their phones and told me if I want to have a portable charger, go for the lithium one that sony Ericsson's is selling.
hi,
i'm using varta charger type 57048:
http://www.amazon.de/Varta-Professi...=sr_1_3?ie=UTF8&s=ce-de&qid=1291062768&sr=8-3
and i don't want to miss it on longer journeys. the usb-out function i would say is nearly as fast as the normal charger. one akku pack is enough for about 2 charges. if you are on a journey and not able to charge the akkus you can buy normal batteries. they give about 1 charge.
i have experiences with other chargers and phones and i would say this thing works really good because the usb-port of the charger turns off when batteries haven't enough voltage. this prevents your x10 battery from damage because wrong charging.

My x10a mini pro came with 970 mAh battery, not 930. Battery life is about a day and 1/2. I use USB car charger in the car on needed basis only. Hopefully USB car charger doesn't fry the battery.

wireless battery

hello
i am looking for wireless battery for our xperias. (EP500)
look this link:
http://www.letstalk.com/blog/post.htm?blogId=1214
anyone know where i can buy one?
regards
this is not a good option, because a wireless battery charge is sloooow, and live time of charge is short. sorry, my english is bad, i know
I would love to have this. No more ****ing around with cables, just lie the phone on a pad. I don't care if it charges in 1 hour or in 4 hours and i don't care about a slight reduction in capacity.
I don't think it's gonna be availabe any time soon though :-(
Hopefully someone smart will mod a battery with a powermat and write a guide on how to do it yourself.
thats awesome, if someone find this somewhere on the internet please post a link.
i think this is not a good idea
you gotta be kidding me
is it serious wireless battery???
Wireless battery? Really?
Do you mean portable charger?
You could build it yourself with the Palm Touchstone and a backcover of the Palm Pre.

I can't ensure that the testpoints are the right ones, but currently it's working great and charges the battery with around 400mA. For an empty battery it takes 2-3 hours to full charge.

Shutting down at 45% charge

My phone keep shutting down when charged at 45%.
It refuses to start up again (or just starts up and then shuts down).
I have Googled it and so many answers come up.
Should I just "splash out" on a new battery or is it something more serious?
I have had the phone for just under 18 months.
It gets heavily used because it is for development too. So it is plugged in to my computer a very large amount of the time.
I noticed that someone mentioned about it getting hot.
How hot is hot? Mine does get warm a bit.
I have it in a leather case that is open on the sides but closed front and back and I am wondering whether it could have overheated and caused damage.
Looks like this: http://ecx.images-amazon.com/images/I/41DdBaqlfLL.jpg
A bit warm is not hot..does it charge to 100% after you reboot and continue charging?you could try calibrating your battery with some calibration app

I think that problem is in battery overheating. Somethimes when battery is hotter than 50 C ur phone just freeze itself and do a reboot. Try to play some hd games when u charging ur phone and ur phone will probably do a reboot. Is it overclocked?

Yeah. It seems to have no problem charging up again.
I installed DX Toolbox. It has a battery-charge screen. You can follow the charge process as it move from fast-charge -> cycle-charge -> trickle-charge.
Shows it is ok and fully charged and it still tends to shutdown when it reaches 45% or so.
I have been charging mostly from my computer since it is connected there most of the day. Also, I lost my original charger. I do have another non-SE charger (Samsung) at work that I use sometimes. It charges with no problems.
However, the problems started long before I used the other charger.

I'll keep an eye on the temp to see if it is getting to 50 C.
My clock is not overclocked and I am using the stock ROM 2.3.3.
I would be ok moving to another ROM if that would solve the problem - although I would probably lose my Hebrew.
I should add the fact that it doesn't always happen.
For example, I am not at 33% and still "alive".
Will probably die if I start Angry Birds.
LOL - Shoulda shut up.
Just after I typed this it shut down. Without anything extra running.
Try another kernel, like zKernel for stock 2.3.3 (locked bl).

According to the post on it, it has the debuggable option removed.
That's a problem for me since my device is used for development,
If its an original LiPo battery, def. get a new Li-Ion one. I had similar issue and got a new genuine LiIon battery for X1 (same model number BST-41 i think from memory?), fixed it right up.

Yep. Original Li-Po battery.

Well I guess my one is just an extremely good quality copy then. It came in retail packaging, the hologram sticker thing looked perfect, it looks just like original BST-41 but says Li-Ion instead of Li-Polymer. It was $40 on eBay Australia.
I thought it might be a copy (not genuine) but it works VERY well. So I'm happy either way. It was listed as "*Genuine* Replacement Battery for Sony Ericsson X1 (BST-41)" or something.
Can u give me a link? Is temp lower than a stock LiPo battery?

I checked Fast Recharge app while updating some Market apps for the past ten minutes and it said 27 degrees C. I don't know how hot it gets while charging, I'll check tonight if you want. It also says the battery type is a Li-Poly, so I don't really know if it is a Li-Ion - it just says so.
The original seller of the battery doesn't have the item listed anymore and google cache won't show the original eBay page either I have spent the past ten minutes trying to find a "genuine-looking" BST-41 but they all say Li-Polymer. This is really weird. I have searched for all the numbers and still found nothing on any site in any country.
OK, I've found one close match but it's alibaba (wholesale from china) so you probably can't get it unless you're willing to buy a batch =\
http://wincent-do.en.alibaba.com/pr...BST_41_li_ion_polymer_1500_mAh_wholesale.html
I found it by googling for (with the double quotes intact):
"BST-41" Genuine "Li-Ion" Retail
...maybe you will have better luck. I noticed the Xperia Play also uses the BST-41.
Sorry I can't help more. I compared my battery to the Fake Vs. Pro thread here with the nice high-res photo's, and this Li-Ion has a perfect hologram. Anyway, I have added photo's of the battery in that thread - see my post here.

[Q] check for original charger

i bought a charger online it looks very much like the original bundled one. However i have a couple of questions
1. is there a way i can check the output quality using the phone itself and not a multimeter . Like variation in voltage/current?
2. using a multimeter do i have to tear apart the charger to check the output quality.
any inputs are welcome

Depends on what you mean by 'output quality'. If you mean the ripple (noise), especially in response to load changes, then no, you can't without oscilloscope and dummy load.
If you do not have this measuring equipment, then I would use these two simple tests:
does the empty phone fully charge within 2 - 3 hours ?
does the touchscreen stay responsive while charging ?
If you can answer both of these questions with yes then one could assume the charger is of good quality.
thanx for an informative reply man. the thing is i use usb charger usually battery is 8 months old . i dont know how long it will charger to recharge. giving these conditions u still think it will take 2-3 hours to charge ? yes the touchscreen stays remains but i think there is the usual "noise " that makes minor error in touchscreen smoothness. do u understand wat i am trying to tell u.

the minor 'touch screen smoothness' issue will be there while charging thro wall charger for sure and also the charging time do wary depending on how old the battery is

If the battery is fine (and it should still be after 8 months) charging of an empty battery should happen within 2 - 3 hours.
