Z3 compact lag

[betrue2yourself]

HI there!

So, I bought the gadget few weeks ago in December. Everything was ok till yesterday.

The phone started to lag. Antutu benchmark has shown 37-38k instead of usual 45-46k. While performing video tests - very hard lags and the downfall of fps from usual 40 to 27-28.

The lag dissapears when connected to the charger. Already tried to hard reset/to work in Safe Mode - nothing helped. What is the issue can be?

Thanks in advance!

Do you have stamina mode enabled?

[betrue2yourself]

No, I do not use it at all.

Could you perform a software repair? Safe mode should help in your case but I see it doesn't.

[betrue2yourself]

You mean usual Reset to Factory Settings? Now performing. Hope that helps but do not think so. Will let you know shortly about the results.

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
