Problems with Experia E,model C1504

[SKJC1504]

Hi,

I am user of ExperiaE,C1504 mob and I am having hard time in using it due to its frequent hangs,slow processing,battery draining out uckly and all.May you please suggest some solutions to it.The software I am using is the latest and I have a good amount of RAM freed~200Mb.Still I couldn't figure out its sluggishness and battery drain.

Did you say you have 200 MB of free RAM on Xperia E? That's surprising. Have you rooted your phone?
Anyway, to slow down battery drain, turn down screen brightness to about 50 %. Switch off data and Wi-Fi when you don't use them. Turn on Stamina mode and do not allow exceptions. How long does a single charge last? What app uses the battery most? Settings - Power management - Battery usage.
To reduce the lag, stop using live wallpapers, widgets, task killers and do not use more than one instant messaging apps. Avoid third party launchers unless you are sure they use less RAM than Xperia Home. Disable apps that you don't use like Email, Gmail, Facebook, YouTube, Talk or Hangout, Google plus and Google search.

do you use any kind of battery saver task killer or antivirus???

If nothing works, do a factory reset, or a repair through Sony Update Service. Backup contacts and other important data beforehand.

[SKJC1504]

Nope

[Danial-mach1]

so as agape adviced you can either using factory reset or software repair

try your phone in safe mod(how to boot in safe mode)

see problem persist there

[SKJC1504]

Yes I tried in safe mode and the problem still persist.Anyway I have now uninstall 'clean Master'. Lets see if it helps.
