Verdict
The clearest difference is in-app purchases: Olive at none against Life Battery's 3. Olive also leads on ads (none vs shown) and iOS requirement (8.0 vs 18.0). Life Battery's advantage is update cadence (every 4 days vs every 37 months). On price and device support there is nothing between them.
