I will have to disagree. AFAIK, the recent Qualcomm exploits don't affect Samsung's Exynos SoC. I have an Exynos S7 Edge and it ships with a feature to disallow (read: kill) apps trying to work in the background. After I fine-tuned this list, the phone's battery life improved noticeably.

Battery life has actually been slowly and steadily improving after each update by Samsung. I imagine this is a sign of Samsung not liking Google's spyware very much and trying their best to limit background activity.

None of us has solid proof of course, but judging by observable facts (and by the pretty awful battery life of the Nexus 6P and the Pixels -- compared to the Exynos S7 Edge at least), I'd say mine aren't that crazy.
