Ok, so I have a few questions about extended vs. stock batteries for Droid 3. I just ordered a Hyperion 3500 mah extended battery (link: Amazon.com: Hyperion Motorola DROID 3 Global 3500mAh Extended Battery + Back Cover: Cell Phones & Accessories) to try to really max out my battery life but here's the thing: I've been running Steel Droid 4.5 for about 2 weeks and have experienced pretty good battery life (about 50% by the time I'd be going to sleep with moderate use). However, and I don't exactly know how/why, but my phone is now on over 4 days with 13% still left (AWESOME). Granted my talk times only been about 2 hours, some texting, light internet use, etc. which are below average for me but still over 4 days seems insane to me. Some extra info: I keep my phone on the darkest display, use "Ultimate" setting on AutoKiller Memory Optimizer w/ advanced tweaks (SD, Memory Management, Battery*, UI, Network, and Wifi), use Extended Controls to generally keep off Wifi, Bluetooth, Sync, GPS (until I want to use obv), use Data Enabler to keep off 3G (until I want to use), use Timeriffic to go to Airplane mode from 1am-6am during the week, recently switched from AVG to Avast for anti-virus. Questions: anyone have any review of either the Hyperion extended battery or other 3500 mah ones? Is it even worth switching considering the crazy battery life I just got? Anyone else have similar experience or opinion as to HOW this happened? Any other tips/comments? Bring it on, I'm pumped.
