Tap a question to see the answer.
Short answer: the complication on your watch face is the old one, from a version of Battery Life before 26.8.1. It cannot receive new readings any more. Remove it from the watch face and add Battery Life again — it takes about fifteen seconds and only has to be done once.
1. Press and hold the watch face on your Apple Watch.
2. Tap Edit.
3. Swipe left to the Complications page.
4. Tap the slot that shows the stuck Battery Life reading.
5. Scroll to Battery Life and select one of the three complications.
6. Press the Digital Crown to finish.
Some delay is normal. iOS decides when an app in the background is allowed to run, so a notification typically arrives 5 to 60 minutes after your battery reaches the level you set. This is a limit of iOS itself and no app can work around it.
If notifications are much later than that, or never arrive, check these three things:
Don't swipe it away in the app switcher. A closed app can't check your battery state until you open it again.
Settings › General › Background App Refresh, and make sure it's on for Battery Life. Apple explains the setting here.
Low Power Mode cuts background activity, which stops notifications arriving on time. It switches on by itself at 20% battery, so it may be active without you setting it.
Still nothing after all three? Get in touch and we'll take a look.
External devices only report their charge while they're actively connected to your iPhone. Once a device disconnects — out of range, powered off, or in its case — Battery Life keeps showing the last level it received rather than guessing.
That's why each reading carries the time it arrived. If a figure looks stale, reconnect the device and it will update on its own shortly afterwards.
A device that never appears at all usually just needs to be connected once while Battery Life is open.
Restoring your purchase should sort it out. Open the More tab and choose In-App Purchases — the restore option is there.
One thing to check first: purchases belong to the Apple Account that bought them. If you've since switched accounts, or you're setting up a device that's signed in with a different one, sign back in with the account you originally used and restore again.
If Pro still doesn't unlock after that, let us know.
Refunds are handled entirely by Apple — we have no access to your purchase and can't issue one ourselves.

Starting with iOS 13, Apple stopped letting apps read the detailed battery values. Battery Life can no longer show:
This is a restriction in iOS rather than something the app can work around — we'd show these again the moment Apple allows it.
On iPhone you can still see your maximum capacity yourself, in Settings › Battery › Battery Health & Charging.
No. Battery Life reads values your device already keeps track of and does no heavy work of its own, so its own consumption is negligible.
If you're checking Settings › Battery and see Battery Life listed, that's normal — every app that has run appears there. The figure reflects the time you spent looking at the app, not extra drain caused by monitoring.
These three signs usually mean the battery is near the end of its useful life:
On iPhone you can check the first one in Settings › Battery › Battery Health & Charging. If any of these apply, a battery replacement from Apple or an authorised service provider will restore normal runtimes — it's a routine, inexpensive repair.
Don't overthink it. Apple devices use lithium-ion batteries that cannot be overcharged under normal conditions, so leaving your device on the charger overnight is safe.
Batteries do last longest when the charge stays roughly between 10% and 80%, but watching it that closely makes a phone impractical to use — and iOS already does much of this for you. Optimized Battery Charging learns your routine and holds the charge at 80% until shortly before you normally unplug. On iPhone you'll find it in Settings › Battery › Battery Health & Charging.
Heat is what really matters. Some cases trap enough heat while charging to reduce capacity over time. If your device gets warm on the charger, take it out of the case first.
Apple has a good explanation of how these batteries work if you'd like the detail.
The biggest wins are usually screen brightness, turning off Background App Refresh for apps you don't need it for, and using Wi-Fi instead of cellular where you can.
Apple's own guide goes through the rest: maximizing battery performance.
