Battery

4,300mAh

From a 10K power bank

≈ 1.7 full charges

A smaller phone battery whose real Wh figure produces more full charges from the same power bank than most large Android flagships.

Battery

3,349mAh

From a 10K power bank

≈ 2.1 full charges

Battery

4,422mAh

From a 10K power bank

≈ 1.6 full charges

A compact 12.68Wh reference that shows why phone-specific energy is more useful than a generic 15Wh assumption.

Battery

3,279mAh

From a 10K power bank

≈ 2.2 full charges

A large iPhone battery whose power-bank charge count is much closer to current flagship Android phones than the standard iPhone 14.

Battery

4,323mAh

From a 10K power bank

≈ 1.7 full charges

The smallest Galaxy S24 battery, with a clearly separated 3,880mAh rated minimum and 4,000mAh typical capacity.

Battery

3,880mAh

From a 10K power bank

≈ 1.8 full charges

The larger S24+ stores substantially more energy than the standard S24 and therefore gets fewer complete charges from the same pack.

Battery

4,755mAh

From a 10K power bank

≈ 1.5 full charges

A compact Galaxy flagship with a 3,785mAh rated minimum and a separately stated 3,900mAh typical capacity.

Battery

From a 10K power bank

≈ 1.9 full charges

The S23+ carries about 21% more rated energy than the standard S23 and needs a correspondingly larger power-bank reserve.

Battery

4,565mAh

From a 10K power bank

≈ 1.6 full charges

The larger non-Pro iPhone 15 stores substantially more energy than the standard model and lands close to the Pro Max.

Battery

4,383mAh

From a 10K power bank

≈ 1.6 full charges

The smallest battery in this library, showing why one fixed phone-size assumption can badly understate charge count.

Battery

2,406mAh

From a 10K power bank

≈ 3 full charges

A compact mainstream iPhone battery that sits between the 13 mini and the much larger 13 Pro Max.

Battery

3,227mAh
