PhoneBattery
Your battery, on your wrist
Free · In-App Purchases
PhoneBattery is the tiny little app that solves a surprisingly annoying problem
How much battery is left on your iPhone? And why do you need to dig it out of your pocket every time just to find out?
With PhoneBattery, you can simply glance at your Apple Watch and boom — mystery solved.
Perfect for:
• Workouts where your phone is buried somewhere in a sweaty pocket
• Busy commutes with too many bags and not enough hands
• Couch-days where the phone is just a little too far away
No magic. No fuss. Just your iPhone battery, right where it should be: on your wrist.
FEATURES
• Smart battery notifications (never get caught at 2 percent again)
• Clean and simple interface (nothing extra, no clutter)
• Lots of Apple Watch complications
• Alternative app icons (because vibes matter)
• Free, no ads, and made by one indie developer
• Optional tips if you want to support future features

PhoneBattery has been thoroughly updated for iOS 26 and watchOS 26, including support for the new Liquid Glass system design. The app is now also available in Spanish, Italian, French, and Simplified Chinese. Home Screen app icons now fully support the new customization options. I’ve also fixed a few bugs and improved overall stability.

3.0 07/06/2023
Minor bugfixes and improvements
2.0.4 14/03/2020
- add support for iOS 13
- update Swift version reducing binary size
Thanks to everyone who has donated in the past. I'll see if I can bring it back in a future version.
As always, thanks for using PhoneBattery! If you like it, please leave a review in the App Store.
2.0.3 05/10/2019
Bugfixes, removal of Crashlytics/Fabric, adjustments for new watches and phones
2.0.2 19/02/2019
Unfortunately, a couple of bugs have sneaked into the 2.0 release. This update fixes most of them (and also adds new App Store screenshots that mysteriously disappeared during the release of the previous version).
Improvements:
- fixes a problem with missing German localization for two icons
- adds a simple guide to the notifications settings within the app, explaining how often you’ll receive notifications and why you might have not received a notification yet even though you enabled it
Thanks for using PhoneBattery! Your feedback for the release of 2.0 has been overwhelming. If you like it, consider donating a small amount within the app to help keeping this app maintained or rate it on the App Store! It really helps to stay motivated.
2.0.1 02/08/2018
It's finally here! I've listened to you and I am super sorry that it took this long (almost 3 years in fact) but this update is basically the mother of all updates! It's the first big update to PhoneBattery with lots of changes and a couple of new (but super useful) features. Thanks for your ongoing support and your kind words in the past! I really hope you'll enjoy PhoneBattery 2 - and yes, it'll work on an upcoming watchOS update.
New:
- two different watch interfaces to choose from (a circular interface and an interface that resembles a battery)
- battery state notifications
- new battery states (low power mode enabled and low battery state)
- new default app icon (don't worry, you can switch to the old one at any time if you want to)
- alternative app icons for the iOS app
Improvements:
- higher data accuracy and way faster data transportation between Apple Watch and iPhone
- various bugfixes
- interface tweaks
- all new codebase (although, this is more of a behind the scenes thing which you'll barely notice)
- optionally support its development and further updates by donating
- add native SKStoreReviewController for user reviews (used for non-intrusive App Store review requests)
- transition from watchOS 1 to watchOS 3 (it's fully native now and at least 300% more awesome than before – I know, this one was overdue)
Important: this update only includes English and German localisation due to the complete rewrite. Don't worry, the other localisations will return soon. This update will no longer support watchOS 1 and watchOS 2. Update to watchOS 3 before updating to PhoneBattery 2. If you're interested in localizing PhoneBattery to another language, please contact me on Twitter or using the "Help" button within PhoneBattery.
