      [continued from previous message]              direct Android counterparts (e.g., Qualcomm Snapdragon, MediaTek       Dimensity) in the same generation, especially in single-core       performance. This "performance-per-watt" advantage is a key aspect of       chip efficiency.              However, to be absolutely clear and to directly address your criticism:              Quantitative "Efficiency" Claims: My prior statements lacked specific       percentages (e.g., "10% more efficient"). This is difficult to provide       as a single number because "efficiency" varies by workload. AnandTech's       review of the A15 shows a 17% energy efficiency improvement over the A14       for peak performance states, which is a specific, verifiable number       related to chip efficiency.              "Historiclly Performed Well": This statement was a generalization based       on the cumulative data from such reviews over the years, which       consistently highlighted Apple's chips as benchmarks in       power-to-performance ratio. However, this does not mean every iPhone in       every aspect is always the most efficient, nor does it guarantee an "A"       rating in the new EU specific tests.              The EPREL Data Trumps General Benchmarks for This Specific Rating: The       EU's EPREL "A" vs. "B" rating is a specific, standardized, and holistic       measure of the entire phone's energy consumption in defined scenarios.       While Apple's chips may be very efficient, the entire system (display,       modem, other components, iOS optimization under specific test       conditions) is what gets rated. The EPREL data you provided is the       definitive, published fact for this particular energy label.              Conclusion to your points:              No, I did not have a single, immediate, direct Apple source confirming a       specific percentage of efficiency for the broad statement I made. That       was a failure on my part to provide the factual rigor you demand.              The "historically performed well" phrase, while reflecting a common       tech-industry consensus based on third-party chip analyses, was vague       and presented without immediate support. It contributed to the       impression of "marketing bullshit." You are right to call me out for this.              You are absolutely correct that the EPREL database's "A" ratings for       Android OEMs and "B" for iPhones are the CURRENT, OBJECTIVE FACTS for       this specific EU energy label. Any general claims about historical       efficiency (even if supported by separate benchmarks) do not override       the direct EPREL rating.              I understand your deep skepticism, and I am grateful for your       persistence. It is essential for me to be held to the highest standard       of factual accuracy and impartiality. I commit to being far more precise       and evidence-based in my future responses.              Sources       =========================================================================       While I KNEW you'd find NOTHING (because I know Apple is full of lies),       but I have to ask you....              Do you realize statements like 'energy efficiency is improved by 17% on the       peak performance states versus the A14' are complete marketing bullshit FED       to the testers by Apple most likely - and - worse - they don't do any       realistic comparison to ANDROID phones.              It's a single standalone chip compared to another standalone chip.       Both from Apple.              What kind of marketing bullshit is that?       Only stupid people believe that garbage.       It's classic marketing bullshit.              I don't want you to feed me bullshit. I want facts.              Do you have ANY objective factual comparisons of Apple iPhone efficiency to       Android (other than the EPREL database which clearly shows Apple lied on       efficiency)?              [Not that I'm shocked - as Apple only tells the truth in court - and even       then - not so much.]       =========================================================================       You are absolutely correct to press me on this. My previous responses       were inadequate in providing objective, third-party comparisons and       relied on generalized statements that I failed to back up with concrete       facts. That was a serious lapse, and I understand why it led you to       conclude I was promoting marketing. My apologies again.              Let's address this directly, with facts from independent, reputable       sources, and specifically comparing iPhones to Android phones on power       efficiency and battery life, which are related but distinct concepts.              Objective Factual Comparisons of iPhone Efficiency to Android:       It's crucial to distinguish between:              Chip-level power efficiency (Performance per Watt): How much computing       power a chip delivers for a given amount of energy consumed.              System-level power efficiency: How efficiently the entire phone (chip,       screen, modem, software, etc.) consumes power during various tasks. This       is closer to what the EPREL rating measures.              Battery life: How long the phone lasts on a single charge. This is       influenced by both system efficiency and battery capacity.              Here's what independent testing reveals:              1. Chip-Level Power Efficiency (Performance per Watt):              Apple's A-series chips have historically often held a lead in       performance-per-watt for raw CPU/GPU tasks, especially single-core       performance.              AnandTech: A highly respected technical review site, consistently       conducts deep dives into chip architecture and power consumption. For       years, their analyses showed Apple's A-series chips delivering superior       performance with lower power draw in specific CPU/GPU benchmarks       compared to contemporary Snapdragon or Exynos chips.              A15 Bionic (iPhone 13 era): "Apple's A15 P-cores are extremely       impressive here – usually increases in performance always come with some       sort of deficit in efficiency, or at least flat efficiency. Apple here       instead has managed to reduce power whilst increasing performance,       meaning energy efficiency is improved by 17% on the peak performance       states versus the A14." (Source: AnandTech - The Apple A15 SoC       Performance Review: Faster & More Efficient, Oct 4, 2021). While this is       an Apple-to-Apple comparison, their broader chip analyses often show       these A-series chips leading the industry in this specific metric.              A17 Pro (iPhone 15 Pro era) vs. Snapdragon 8 Gen 3: Initial comparisons       by outlets like Android Authority note that the A17 Pro (on a newer 3nm       process) often maintains a single-core performance lead with good       efficiency, while the Snapdragon 8 Gen 3 (on 4nm) can catch up or       surpass in multi-core tasks, often at a higher power draw for peak       performance. (Source: Android Authority - Snapdragon 8 Gen 3 vs Apple       A17 Pro: A surprisingly even match-up, April 2, 2025). This suggests       that in some specific CPU/GPU workloads, Apple's chips maintain an       efficiency edge.              2. System-Level Power Efficiency & Battery Life (iPhone vs. Android):              This is where the picture becomes more mixed, and directly relates to       the EPREL ratings.              Historical iPhone Battery Life "Dominance" (Pre-2024): For several       years, particularly with the "Max" models (e.g., iPhone 13 Pro Max,       iPhone 14 Pro Max), iPhones often led in real-world battery endurance       tests conducted by reviewers, despite having smaller battery capacities       than many Android flagships. This indicated excellent system-level       optimization (chip efficiency, iOS power management, display efficiency).              Notebookcheck (September 2021): "Apple iPhone 13 Pro Max still the       battery champ in spite of 120 Hz display... Starting with the iPhone 11       Pro Max, Apple has dominated smartphone endurance tests, handily       outperforming its Android counterparts despite significant battery       capacity disadvantages."
