Within hours of Sony acknowledging the bug in Xperia devices, a new firmware for–Xperia Z, ZL, ZR and Tablet Z has reportedly gotten certified.

A new firmware (build number: 10.5.A.0.233) slated for Xperia Z models- C6602 and C6603; Xperia ZL- C6502, C6503, C6506; Xperia ZR - C5502, C5503 and Xperia Tablet Z - SGP321, SGP341, SGP351 variants has received the certifications from PTCRB, a North American Cellular Operators forum, reported Xperia Blog.

Once released, the new software patch is expected to fix the fast battery draining bug, which was noticed soon after Xperia devices got updated to the Android v.4.4.2 KitKat OS last month.

Earlier in the week, Sony Mobile support team had offered tips to temporarily fix the battery draining bug. Users can make some changes in the smartphone settings until the software patch arrives.

The company says that the newly updated Google Play service (v4.4.52) is prime reason for fast battery drain. Users are advised to uninstall the latest Google Play Service update or limit the use of the Google service –YouTube.

If the problem continues to persist then, perform these three steps.

Tip 1:

Settings > Google (accounts) > Ads > Tick the box for Opt out of interest-based ads

Tip 2:

Disable auto back up of your data in cloud storage;

Settings > Backup & reset (Personal) > uncheck the box for 'Back up my data'.

Tip 3:

If unable to uninstall the update for Google Play Services from Settings >> Apps, then

Go to Settings >> Security >> Device administrators and disable 'Android Device Manager'

[Note: users are also said check the settings in the Play Store, so that automatic updates are not enabled as this may update Google Play Services again automatically.]

Though Sony is quick to accept the fault in bug riddled OS update, the company has so far failed to improve their service. It has become routine for the company; every time a new firmware is rolled out to the devices, reports of bugs in the software flood the internet and soon a software patch will be released.

So far, the company has released one software patch and a minor update to Xperia Z1 and Z1 Compact, since they received the Android v4.4.2 KitKat OS in March.
