# FINAL_SUMMARY_v1
|
||||
|
||||
### TECHNICAL_HIGHLIGHTS_v1
|
||||
* **Signal Quality vs. Power Consumption:** The non-linear signal penalty mechanism $P_{net} \propto (\Psi + \epsilon)^{-\kappa}$ represents the most significant driver of rapid drain. In the "Poor Signal" scenario ($S_4$), the TTE dropped from 4.60h to 2.78h, a reduction of approximately 40%.
|
||||
* **Thermal-Electrochemical Coupling:** Cold ambient conditions ($0^\circ\text{C}$) induce a dual penalty: internal resistance $R_0$ increases via Arrhenius kinetics while effective capacity $Q_{eff}$ is restricted. This shifted the termination reason from a gradual `SOC_ZERO` to a premature `V_CUTOFF` at 3.15h.
|
||||
* **CPL-Induced Voltage Instability:** The Constant Power Load (CPL) requirement forces discharge current $I$ to rise as terminal voltage $V_{term}$ falls. This feedback loop accelerates depletion near the end-of-discharge and increases the risk of voltage collapse ($\Delta \le 0$).
|
||||
* **Worst-Case Impact:** The transition from baseline usage to a sustained poor-signal environment ($S_4$) resulted in the maximum observed TTE reduction of **1.82 hours**.
|
||||
|
||||
### MODEL_STRENGTHS_v1
|
||||
1. **Algebraic-Differential Nesting:** By nesting the quadratic CPL current solver within the RK4 integration stages, the model maintains strict physical consistency between power demand and electrochemical state at every sub-step.
|
||||
2. **Continuous Radio Tail Dynamics:** The inclusion of the state variable $w(t)$ with asymmetric time constants ($\tau_{up} \ll \tau_{down}$) allows the model to capture the "tail effect" of high-power network persistence without the numerical overhead of discrete state machines.
|
||||
3. **Rigorous Uncertainty Quantification:** The methodology integrates Saltelli-sampled Sobol indices for parameter sensitivity and Ornstein-Uhlenbeck stochastic processes for usage variability, providing a probabilistic bound on battery life rather than a single point estimate.
|
||||
|
||||
### EXECUTIVE_DATA_SNIPPET
|
||||
Our model predicts a baseline time-to-empty (TTE) of **4.60h** under standard usage at $25^\circ\text{C}$. Environmental stress testing reveals a **31.5% reduction** in TTE during extreme cold ($0^\circ\text{C}$), primarily driven by increased internal resistance and capacity contraction. Uncertainty Quantification (UQ) analysis, accounting for stochastic fluctuations in user behavior, confirms a **90% survival rate** (probability that the device remains powered) up to **4.53h**, demonstrating that while usage is "unpredictable," the battery behavior remains bounded by identifiable physical constraints.
|
||||
|
||||
### FUTURE_WORK_v1
|
||||
1. **Dynamic SOH Aging Laws:** Extend the current framework by implementing a diffusion-limited SEI-layer growth ODE to model long-term capacity fade and resistance growth over hundreds of cycles.
|
||||
2. **Spatial Thermal Distribution:** Transition from a lumped-parameter thermal model to a multi-node spatial network to account for localized heat generation in the CPU and radio modules, enabling more accurate throttling predictions.

-----BEGIN BLOCK_A-----
|
||||
#### 4.4 GPS power and location services
|
||||
Location-based services introduce a distinct power profile characterized by periodic satellite signal acquisition and processing. We define a GPS duty variable $G(t) \in [0,1]$, which acts as a proxy for navigation-intensive usage segments. The GPS power contribution is modeled as:
|
||||
[
|
||||
\boxed{
|
||||
P_{\mathrm{gps}}(G) = P_{\mathrm{gps},0} + k_{\mathrm{gps}} G(t)
|
||||
}
|
||||
]
|
||||
where $P_{\mathrm{gps},0}$ is the baseline receiver standby power and $k_{\mathrm{gps}}$ is the active tracking coefficient [REF-GPS-POWER].
|
||||
-----END BLOCK_A-----
|
||||
|
||||
-----BEGIN BLOCK_B-----
|
||||
#### 10.3 Uncertainty Quantification via Monte Carlo Simulation
|
||||
To quantify the impact of "unpredictable" user behavior on TTE, we employ a Monte Carlo (MC) framework. We generate $M=300$ stochastic usage paths by perturbing the baseline inputs $(L, C, N)$ with Ornstein-Uhlenbeck processes to simulate realistic fluctuations [REF-MONTE-CARLO]. For a fixed seed, we compute the distribution of TTE across these paths. The primary outputs include the mean TTE, the 95% confidence interval, and the empirical survival curve $P(\mathrm{TTE} > t)$, which represents the probability that the device remains operational at time $t$.
|
||||
-----END BLOCK_B-----
|
||||
|
||||
-----BEGIN BLOCK_C-----
|
||||
#### 3.6 Multi-cycle Aging and Time-to-Empty Forecasting
|
||||
While a single discharge reveals immediate performance, the long-term TTE is a function of the cycle index $j$. We implement an outer-loop procedure to bridge the time-scale separation between discharge (seconds) and aging (days):
|
||||
1. Initialize $S_0 = 1$ and battery parameters.
|
||||
2. For each cycle $j$, execute the single-discharge simulation until the cutoff condition $V_{\mathrm{term}} \le V_{\mathrm{cut}}$.
|
||||
3. Record $\mathrm{TTE}_j$ and calculate the total charge throughput $Q_{\mathrm{thr},j} = \int |I(t)| dt$.
|
||||
4. Update the state of health $S_{j+1}$ using the dynamical equation in Section 3.5.
|
||||
5. Update $R_0$ and $Q_{\mathrm{eff}}$ for the subsequent cycle based on the new $S_{j+1}$ [REF-LIION-AGING].
|
||||
This sequence generates a TTE degradation trajectory, capturing how the "remaining life" of the phone contracts as the battery chemically matures.
