A previous Latin Post article has already established that Google will unveil two new Nexus smartphones at a media event in San Francisco this coming Sept. 29.

The upcoming Android 6.0 Marshmallow devices have since been branded as the LG Nexus 5X and Huawei Nexus 6P. But will Google's next generation operating system ever seed to older mobile devices?  

If an updated software release schedule from a major mobile carrier in Canada is to be believed, the answer to that question is an ambiguous yes.

According to information from Telus via Mobile Syrup, the Nexus 5 and Nexus 6 will be the first pair of smartphones to get the Marshmallow update. That isn't too much of a surprise since Nexus devices are always the first to be updated. What might catch people off guard is the update's rumored launch date. 

As posted on Telus' releasing schedule, the Android 6.0 Marshmallow will start seeding to the Nexus 5 and Nexus 6 this Oct. 5. However, the date might only be valid in Canada.

Nexus 5 and 6 users in the U.S. shouldn't worry since it can be inferred that the roll-out will most likely come sooner in the country. At any rate, the Marshmallow update should be seeded not long after Google's media event at the end of this month.

Apart from carrying the expected visual and performance enhancements, Android 6.0 Marshmallow brings improvements in "Android Pay" and "Google Now" while having a new standardize fingerprint scanner and backup data support, Android Pit reported.

The Marshmallow update will surely spell wonders for the aforementioned pair of older Nexus devices, especially for the Nexus 5.

A beta test in August 2015 revealed the Android 6.0 Marshmallow prolongs the Nexus 5's battery life significantly when the handset is left in standby mode.

According to Computer Base via 9to5Mac, results showed a Nexus 5 running on the Android M lasting 300 percent longer than another Nexus 5 running on the Android 5.1.1 Lollipop.

After leaving both devices in standby mode, the Nexus 5 on the Lollipop spent 12 percent charge while the Nexus 5 on Android M consumed only 4.5 percent charge. After a span of two days, the Lollipop Nexus 5 lost 24 percent of battery life while the Android M Nexus 5 only lost nine percent.

Again, the German testers were merely using the first developer beta of the Android 6.0 Marshmallow. Imagine what the final version of Google's next generation OS has in store for Android devices, once it starts rolling out globally.
