Published Galaxy S22+ benchmark. A stationary day at the lower end; driving and map checks at the higher end.
Built around battery efficiency
Keep your people close.
Keep your charge.
Family tracking should leave room for the rest of your day. Zamily reduces repeated GPS work while you’re still, and batches location uploads to save power. Our published Galaxy S22+ benchmark recorded 4–10% daily app drain, with a ~2–5% background-only estimate. See how that compares with the original page’s reported range for other family tracking apps.

Illustrative day · based on the published ranges
Battery through your waking day.
A 6am–midnight illustration with 15% phone baseline drain. The green band adds Zamily’s published 4–10% range; the amber band adds the original page’s reported 18–30% range for other family tracking apps. The curves are illustrative, not hour-by-hour recordings or a matched-device test.

Move. Settle. Adapt.
The Android tracker uses movement and place context to choose when it needs GPS. Remaining still in a trusted place reduces repeated position measurements while device check-ins continue.
Less radio work.
Location points can be batched instead of waking the network for every sample. When connectivity returns, backlog handling keeps older samples from triggering a stream of live alerts.
More features. Same tracker.
Family plans, one-time alerts and temporary sharing use existing location updates. The recent feature release did not add a second background GPS loop.
The original test, kept in view
Numbers with context.
The existing Zamily site published these figures on 28 April 2026 for app v1.2.6, using a Samsung Galaxy S22+ with a nominal 4,500mAh battery. Its source note reported about 4,370mAh remaining capacity after a year of use.
How Zamily was measured
Android’s app-attributed battery statistics were captured across multi-hour periods off the charger using adb shell dumpsys batterystats --charged com.xelora.zamily. The published observations included a stationary-day projection of about 4% over 24 hours and 7–9% on a mixed day with driving.
- Background location enabled, mobile data available and a family with 2–3 other members.
- About 5–10 short map checks per day, roughly 30 seconds each.
- Active navigation, long gaming or video sessions and unusual SOS activity excluded.
Where the other-app range comes from
The original published page attributed 18–30% daily drain for other family tracking apps to public reviews and user reports. Those reports cover different devices and conditions. This is retained as reported comparison context, rather than a paired test against Zamily on the same phone.
What the chart shows
Our published 4–10% daily range and the reported 18–30% other-app range are added to the same illustrative 15% phone baseline. At midnight, that model leaves 75–81% with Zamily, versus 55–67% with the reported other-app range. The time slider explores that illustration; its curves are not new measurements. The ~2–5% Zamily background-only estimate is a separate measure.
This restores the existing benchmark. It does not claim a new test of the current release or the same result on every device. Share your battery observations so we can keep improving it.
