Where is the battery saver setting?
The switch that trades performance for hours has two dominant names, split almost exactly along platform lines. We read the settings tree of all 43 systems in the catalogue and recorded where each one keeps it.
What each system calls it
16 of the 43 operating systems in our catalogue have this setting, and between them they use three different labels for it:
| Name on screen | Systems |
|---|---|
| Battery saver | 8 |
| Low Power Mode | 5 |
| Power saving | 1 |
| Power Saving | 1 |
| Battery Saver | 1 |
The most common is Battery saver, on 8 of the 16. If that is not the word on your screen, the table above is the rest of the vocabulary to try.
Some of those rows differ only in capitalisation — 5 spellings for three actual names. We have kept them apart because that is what is printed on the screen, and a settings search that matches case will tell them apart too.
Where it lives on each system
These are the shortest paths from the first settings screen on the newest release of each system. 13 of the 16 are within two taps; the rest sit deeper, and the table shows how much deeper.

Why the names came out this way
Battery saver is the Android-family phrasing; Low Power Mode is Apple’s. They do similar things — dim the screen, slow background work, cut visual effects — but the names frame it differently: one saves a resource, the other enters a state.
Both live inside the battery screen, and both are the first thing to check when a device is behaving sluggishly for no obvious reason: it may simply have switched itself on at 20%.
Find it on your own device
If your system is not in the table, or the label on your screen is different again, there are three ways through it:
- Search every system at once for a setting by name — it looks inside all 43 trees, not just the one you are holding.
- Open your own system in the settings simulator and click to the screen without changing anything real.
- Follow the step-by-step guide to battery life, or see where that setting lives on every system.
Related settings in the same part of the menu:

- Where is the refresh rate setting?
- Where are the power settings?
All of it comes from the same catalogue: 43 systems, 135 versions, published as an open dataset.

Where is the battery saver setting on most systems?
On 13 of the 16 systems that have it, within two taps of the first settings screen. The most common label is “Battery saver”, used by 8 of them. The table above gives the exact path for each system.
Why can I not find it by searching my settings?
Because settings search matches the label your system uses, and there are three different labels in use for this one setting. Searching for the word your previous device used is the single most common reason a setting appears to be missing.
How many systems have this setting at all?
16 of the 43 operating systems we catalogue. The rest either have no hardware for it or fold the behaviour into something else, which is why a feature that feels universal often is not.
