A question about stock android

[jayctech]

This is just something that occurred to me while watching a Nexus 6 review.

 

While I love stock android and it's my preferred flavor, I've noticed the recent Nexus devices (5, 7, 6) all have bad battery life.

Is it possible OEM's (like Samsung) do some battery optimization?

 

Thoughts?

 

Some battery size comparison:

Nexus 5 - 2300; S4 - 2600

Nexus 6 - 3220; Note 4 - 3220

Please change your title.

Yes, there are ROM's that make better use of the battery. Are you talking about older versions of Android (4.4.4 or lower) or Android 5.0? Because the focus of Android 5.0 was to increase the battery life, and make better use of hardware in general.

That's surprising. According to GSMArena, the Note 4 (86h endurance rating) did better than the Nexus 6 (70h endurance rating) even though the Note 4 is running TouchWiz and the Nexus 6 is running stock. I'm interested to know what the Note 4's battery life will be on stock Android once a custom ROM comes out.

You're comparing devices with completely different hardware. The operating system plays no role in why the Note 4 may last longer. The Note 4 uses a big.LITTLE configuration so the SoC itself is efficient at conserving power. When you're barely doing jack on the device it pushes all of its threads to the power efficient A53 cores but when you need horsepower the A57 cores kick in. If the Nexus 6 ran the Snapdragon 810 the end results would be completely different.

The Nexus 5 and 7 I mention run 4.4 and will upgrade to 5. The Nexus 6 obviously released with 5.

The Samsung devices were just examples I gave (particularly the Note 4) for comparison. Reviews in general state these devices have poor battery life for the size of their battery and when weighed up against the competition.

 

As for the chipsets - that's an interesting thought.. Isn't there another config on the Note 4 with the 805 on it? Any idea of what that one's battery performance is like?

It's probably no better than the Nexus 6 while rocking the same SoC. Also keep in mind the Snapdragon 805 is manufactured on 28nm while the Exynos is manufactured on 20nm. So you can start to see with the big.LITTLE configuration and more power efficient manufacturing node why the Note 4 is better on battery life. Personally I think Google should of just made the Nexus 6 with the Snapdragon 810 (it certainly costs enough). It would of been much faster and a lot better on battery life in comparison to the Snapdragon 805 that it runs now.
