[SOLVED] Huge increase in battery drain in version 1.67 NEON

[thor777]

I just upgraded from 1.65 to 1.67 yesterday and noticed a big improvement on audio definition and clarity. However, I also noticed a huge increase in battery drain after the update. Not sure if I'm the only one or if others are experiencing this as well. I run Neutron on a Cowon Z2.

Hi!

This is strange because on dev. devices in comparison with 1.65 there is performance improvement for single and dual core devices, ARMv7 and ARMv7 + NEON. Have you tried re-installing Neutron? Or, for example try running standard ARMv7 + VFP version and check how it is working on your device.

There is change since 1.65. 1.66 and 1.67 are using new compiler from latest Android NDK.

It would be great to hear about your findings.

Nevermind! It's not Neutron causing the battery drain, it was something I did in the OS. It's working fine now, although I didn't notice any improvement over v1.65. It's draining pretty much the same rate between 1.65 and 1.67.

1.67 is up to 30% faster than 1.65 in NEON version, and up to 80% (for single core), 35% (for dual core) in VFP version. The comparison was made using statistic provided by TOP in ADB SHELL. Devices used for comparison GT-I9000 and GT-I9100. But other devices can show different results. All depends on cache size of CPU and CPU manufacturer.
