I've flashed Xperia Z Jelly Bean v4 (this one http://xdaforums.com/showthread.php?t=2267230&highlight=data) on my Arc S and I can say its so fast and so beautiful.

The only problem I have is that I cant connect to mobile data 3G however my APN settings are correct

I flashed BB-77 too as recommended by one of the users in the thread and it didnt work as well

So what should I do now ?

Thanks :)

Were you able to use the 3G connection before this ROM?

My current advice - Ask from your operator, if the 3G connection is enabled for you.
[Xperia Arc Q&A, Help & Troubleshooting] ChillToucH:
Are you sure you have "Data enabled"? Try to reboot your phone.
[Xperia Arc Q&A, Help & Troubleshooting] MohamedMordi:
Yes I was able to use 3G before this ROM and i contacted my operator and 3G is enabled already

Does that have anything to do with the baseband ??
[Xperia Arc Q&A, Help & Troubleshooting] MohamedMordi:
Already did that and yes im sure data us enabled
[Xperia Arc Q&A, Help & Troubleshooting] MohamedMordi:
Does this issue have anything to do with the baseband ??
[Xperia Arc Q&A, Help & Troubleshooting] 17th_angel:
Well, if in the thread you downloaded it from was nothing more to flash, then nop.

I said it because in GB Roms you must flash an additional libraries, but i dont had used CM10 based ROMs so i can just can guess, check the baseband threads.

By the way, sometimes my phone "losses" the data connection for a while (the icon dessapear even if the data connection is active). It just happen like 2 times since a got it, but after some time it comes back.
[Xperia Arc Q&A, Help & Troubleshooting] ChillToucH:
Flash latest stock 4.0.4 and then install Xperia Z Jelly Bean v4.
[Xperia Arc Q&A, Help & Troubleshooting] MohamedMordi:
Well, in the thread I flashed something called Xperia Arc S 4.1.B.1.13 Vodafone DE firmware and they said it's for increasing system and data memory for Arc user and latest BB. You think this is the problem ?!
[Xperia Arc Q&A, Help & Troubleshooting] TheHaso:
the phone is not set to gsm only?

look at settings - more - mobile network - uncheck 2g

also look at the accesspoin and choose the right one
[Xperia Arc Q&A, Help & Troubleshooting] MohamedMordi:
Guys please this is really urgent and I did everything I could

Last thing i did was flashing every stock thing on the phone, stock GB, stock kernel, stock baseband and nothing changed and data mobile is still not working
[Xperia Arc Q&A, Help & Troubleshooting] pin34gu:

Hi, I bought this phone a month ago, I bought that actually looked like a very good phone, analyze their characteristics, not only its design, and discard the possibility of buying the Samsung S3 Mini, I think it was a mistake :crying:

This Xperia SP is really a headache, the first thing I knew I was bad at was his poor WiFi, later learned of the problem of the screen, which to place the phone on a flat surface the touch becomes useless (I is how to fix it), and now the battery, then I have seen pictures that the battery will last up to 2 days, I was never happened in 14 hours, or when you use it the first time, now active or inactive so I Sstamina gives up to 7 hours, which sucks :eek:.

Originally came with compiling 12.0.A.1.257 and decided to upgrade to the 12.0.A.2.245 to see if suddenly improved, big mistake, the 2245 presents many problems in the stability of the OS, the screen flashes when using certain applications , Stamina mode is "Arrangement" a bit, as the cell I last up to 12 hours, but it's all over.

In conclusion I am determined to get rid of this phone, and all who ask for me, I gonna Scream, NEVER BUY THAT MTF CELL, which by the way is a bit expensive for the problems to come.

Sorry, my english is not very good :silly:
[Xperia SP Q&A, Help & Troubleshooting] yo-meister:
how many apps are you running?

That standby time seems ridiculous...

Heres mine and I have 41% battery.

I've heard about problems with wifi and touch but never had either of them, try and exchange your phone if its getting that bad.
[Xperia SP Q&A, Help & Troubleshooting] ykdr-scott:
To be honest with you- the WiFi does suck on the sp, even though there are many fixes none of which will work 100% . Ive come across alot of problems with my sp also, keyboard wont pop up, walkman crashes when using certain apps. But on the plus note there is deffo an upside to the sp compared to most other mid range smart phones out there.

I have smashed my screen on my sp and have no warrenty- so im switching over to a s3 mini, simply because a new white digitiser for my phone would cost me £135.

Play around with your phone first see if you can make any good of it before you sell up

Whats your screen on time? Also ho do you use your phone? Heavy gaming or light texting only?

Things will always matter when you want to compare battery life. So give us more details. Install Wakelock detector or BetterBatteryStats to know what is eating up the battery on your phone and then work on eliminating the factor. Cheers man!

I do not play much, texting, only play when I'm charging the phone, cut the rope and Diamon Dash.

After it, I think do a factory reset, to see how it behaves. :o
[Xperia SP Q&A, Help & Troubleshooting] sarkar1990:
I think you should. Your Android OS is using too much battery. Hit on it and check which process is using the maximum battery.

Battery life not quite as good as I hoped

The battery life on my xperia SP is not bad but it is no better than my previous xperia neo which had only a 1500mah battery versus 2370mah.

Many reviewers have commented that they can get through 2 days.

I can only make 1 and a bit. The key problem appears to be the screen. I can use the screen for about 4 hours/day before I'm out of juice, some reviewers claim 7 hours. Thats a big difference. Using it outside of the time is always going to be worse but screen on time is a bit disappointing for me. Stamina with screen off seems reasonable but again not outstanding. I lost 13% between the morning and lunchtime without doing anything but 15 minute syncing, I use a battery saver, not stamina mode as I don't want to shut down all my apps and have no data at all when screen is off.

Phone is only 2 weeks old, can I recalibrate the battery? Seems to stay on 1% for a while too. On the contrary, my wifi reception is really good. Better than any other phone I've had.
[Xperia SP Q&A, Help & Troubleshooting] :
I had a Pro, the QWERTY variant of the Neo. The SP has the same battery life for me, which is about 7 to 10 hours

Go to Settings>Power management>STAMINA mode and add apps you want to stay connected, like Facebook, Google accounts, MyXperia...whatever app you want to keep connected to the internet

Yes you can, but you need to root your phone. Some people say its useless to do It, but you can try.
[Xperia SP Q&A, Help & Troubleshooting] vieose:
Got a bug less device :D :p
[Xperia SP Q&A, Help & Troubleshooting] Parkside:
Battery life on standby is perfectly good for me – a few people have said that the estimate Stamina mode gives is based on recent usage. So if you haven’t had the device very long of have just had a big session on your phone the estimate might not be very accurate.

Most mornings the battery is 0, 1 or 2% down on the reading before I went to sleep…deep sleep is being enforced.

However, I don’t think the battery consumption with screen on is anything special – not bad, not exceptional.

It’s a really good phone IMO. I admit WiFi seems badly implemented and you shouldn’t need the tweak which seems to fix it for most rooted users (all manufacturers seem to still release phones with Wifi problems). But with this tweak in place I get better wifi than my old xperia (it had a custom kernel that gave it awesome range) and better than my wife’s Samsung S2. There’s a part of my house where we couldn’t get any signal for my old phone or laptops – amazingly the SP can connect!

My C5303 drained battery like hell, with less than 5 minutes on screen time, it drained 2% per hour.

bluetooth, nfc, wifi, data disabled( sim card does not have data), mobile network wcdma or gsm only

stock .245 generic RU rom rooted with bbs installed,

top of the list wakelock : superstamina xssm (nobody in this forum can fix it)

battery drains : cell standby and phone idle

already factory reset over 5 times, nothing works

is it a rom problem? app problem? simcard problem or battery calibrating problem?

really need some advice here, had been stuck with this ****ty battery life for 2 motnhs
[Xperia SP Q&A, Help & Troubleshooting] esloded:
I think that is a problem in the OS of the SP, as put or dimly lit screen this will still consume battery as much lighting.

In my case the problem was corrected a bit, I deleted widgets, some app that did not use, the antivirus was always eating, I set to use 3G only when I need it, otherwise I'm on 2g most of the time, not game unless it is connected to the charger, WiFi and GPS only when I need them, listen to music and write a little and this we see is the result, compared to what it was prior is something a little encouragement :) ...(Attached)

But, why have a midrange phone if you will not be able to use to stop because two hours is dead? the Sony need to fix that big waste of battery.

I will continue to see what happens, disconcerted me the Android OS consumes much battery 45% to 52% long :(

Please, helpme whit this, why there are applications that I am using, or have not opened, but are consuming battery?, How do I prevent them from running without my wants? any program to control the apps that connect to the internet? :rolleyes:
[Xperia SP Q&A, Help & Troubleshooting] sarkar1990:
Check which processes in Android OS is running the most. Install Wakelock Detector and that should help you get there

Also, hibernate apps that are running in background. Use Greenify for the same.

In the images posted I can see Mcafee and Lookout. I would suggest removing Mcafee as I have found it to be a resource hog, my opinion though. Either way u need to get rid of one of them.

In another image I noticed wifi is always on. Go to Settings -> Wifi -> menu, advanced -> Keep wifi on only when connected to charger one. That will reduce wifi wake usage.

get Juicedefenderfrom HERE OR

Snapdragon BatteryGuru from Here

If using Juice defender, set to balanced/aggressive.

If using Viber, go into viber -> more options -> settings -> wifi sleep policy -> change to use device settings not always on.

Zero the battery and do a full charge. Post updated screens when battery is under 30% ( Please include the MISC Usage screen from BBS). I expect it will be 2 days before we see those screens.

If you can even post a screen of the Misc usage from BBS just now and we`ll compare it with the next one soon. :P

I use JD (gives me a 1.5x boost to battery) with Stamina Mode on (no low battery or wifi). I charge my phone on an average once in 2 days, medium.

Well, after trying a bit with some applications that could work to fix the problem a little drained from the battery, it seems that yesterday I could finally move forward more than I expected, for the first time Battery Manager gave me more than 1 day-long :victory:, of course, with all disabled as Jambu95 friend, and I do not know is that the Zero Apps??

I could tell that it consumes more battery within the Android OS process is the Media Server, and can be solved or how it works for this consume less battery without affecting the functioning of the cell? :confused:

The applications that currently run and monitor the use of my battery are:

Deep Sleep Battery Saver Here

Battery Stats Plus Here

Better Battery Stats Here and the free version in XDA for Chamonix ------>> Here

Wakelock Detector Here

CurrentWidget Here

Juice Defender Here

Greenify (don´t work for me, i´m not root) Here

Then, after setting them up as I think they work well, the result began to give, but I'm pretty sure I should not have all those app installed, which left me and could tell which uninstall?? because they have such app that constantly monitor the battery and processor usage will be affected as well as the battery, and the remedy will be more like a disease, or am I wrong?...

Now I will review this guide that speaks of draining the battery and use CurrentWidget to help us find and fix the problem, then tell them how I keep going with this bloody SP that is beginning to look less bad :good:

I've said it on several threads regarding battery drain, mine did the same for the first week or so after flashing new fw, I'd get 12-16h battery, xssm (stamina mode) causing huge amount of wakelocks, but after a week or so I now get 24h easy with 3-4h screen on time. I use no power saving apps, loc based WiFi is on, screen 100% with autobrightness, mob data, autosync, GPS, nfc, always on.

I really don't know why some of you are having so many issues, all I can suggest is that you let your phone settle in for a bit and see if it improves.

Another thing, media server can cause big drain if you have a faulty mp3 file or similar on your phone.

You can uninstall it, open the app, in the settings there is an option to uninstall it, but beware, first make sure you have the password to unlock the McAfee since when trying to uninstall it from that option the phone will be locked and will ask for the code release, so make sure you have it before trying something :fingers-crossed:

WiFi reception seems to be a hardware issue. Some users have no problem. Others get bad connection which slightly better by fixes. Mine is superb. Better than any previous phone I've owned with higher WiFi signal strength (-45 versus -50 for my old phone in same place). Oddly my girlfriend got s4 mini at same time. And her WiFi is awful and drops out often. Her signal is also worse (-60). So maybe it's soldering issue with many phones. Does seem to be hardware. Check your signal using WiFi analyser and if it's worse than another phone may be faulty antenna (software fixes just make it stay connected at lower signal strength.

Battery life is more complicated. I'm not sure stamina mode is that good. Gives me better estimation but reality is down to 50 percent with very little use. I'd normally be on 85 percent without it on. I use 2x battery saver. Enables internet every 30 mins when screen is off. Mine will usually last 1 to 1.5 days so nightly charge is essential. 4 to 5 hours max screen on time.
