Yes — Mister Battery supports the iPhone 17. You should be able to use all the features normally on your new device. If you run into any issues or something doesn’t seem to work quite right, please let me know — I’m happy to help! 👍 ### 4/5 — Very nice app *2024-02-19, version 4.1* I give 4 stars because every app can use improvements. Very nice app ### 4/5 — 良いと思う *2023-06-25* たぶん… ### 3/5 — 偵測問題 *2021-11-22, version 3.9* 還是讀取不到 官方買的20w充電器 一直顯示未知 ### 4/5 — New Funktion please *2021-10-19* Full Charge time Charge min, Max and AVG Watt please… ### 4/5 — 簡易チェックには十分かも *2021-07-21* おおよその目安には十分使えるが、ハードチェッカーの様には使えない。 しかし、残量や充電器の性能を把握していれば、バッテリーの状態を憶測できるくらいの大まかな判断が出せるくらい。 ただ、残念なのは第5世代のiPad Pro 12.9に関して言えば、多分設定？が間違っていて、100V対応の充電器で充電しても最大で10V超す程度、5Vや10Vの充電器で充電しても数Wの表示。充電器は触るとそこそこの熱さなので、1/3程度の表示になっている感じがする。 iPhone シリーズ、iPad Airシリーズは、持ってる物では、誤表示はない感じがする。 ### 3/5 — Iphone,ipad都不錯用 *2021-06-28, version 3.7* 但Apple Watch卻不能用無法顯示 請問怎會這樣？ ### 2/5 — 結果不準確 *2021-05-11, version 3.7* 多次結果不準確 ### 3/5 — 厳密な電力表示ではない *2021-04-17* タイマーを開始してから終了するまでの時間あたりに増えた電池残量から充電電力を求めているようです。 入力電圧と電流を測定した値によるものではないため、購入した充電アダプタの性能評価には向いてなさそう（比較はできる）。 ### 2/5 — 嗨 *2021-03-22, version 3.7* 為什麼會有100元刷卡紀錄...？ ### 4/5 — Great app, just a few issues. *2021-01-24, version 3.7* I have an iPhone 8, and it says the best charging for this phone is 12 watts, when it’s fast charge capable, with 18 watts. However when I’m charging at 18 watts. It doesn’t say it’s charging over 12 watts. Apart from that, it’s a great app for knowing what your device is charging at. ### 5/5 — 好用 *2020-11-17, version 3.7* 好用 就是$23比較貴 ## Most critical reviews (10 lowest-rated) ### 1/5 — Scam *2026-01-30, version 4.2* Doesn’t work. Scam. Spent over 8 mins multiple times and won’t record a test or give any info… how does this have over 4 stars. Scam scam scam scam ### 1/5 — Never worked *2022-10-14, version 3.9* Do not buy, it doesn’t work. Shows no data. ### 1/5 — Not compatible with iPhone 14 Pro *2022-10-08, version 3.9* Says max charging speed is 30w, it’s not, it’s 27w. Also the icons in the top menu bar can’t be clicked because they are cropped. ### 1/5 — Where are the instructions? *2022-09-01, version 3.9* ‘App support’ takes you to a dead Twitter account so I guess the only way to share is here. The frustrating thing is that there are no directions giving you even parameters for how much time a “test“ should take. * Is this a.m. “plug it in and let it run for 1-2 minutes and get the results for how effectively you are charging your phone“ kind of app? * Or is it a “leave it running in the background for two weeks while you experiment with different chargers giving your phone a full charge” kind of app? —who knows.. I can say that if it’s the first, it doesn’t work at all: 5w charger—20w chargers— they all scored in the same 3.7-7.3w range. There’s my $2.00 education 🙄🤣 ### 1/5 — Doesn’t work *2021-12-11, version 3.9* I PAID, and downloaded the app. Ran the test 4 times. The most recent test I ran for over 5 minutes and it never showed any results. It just runs but doesn’t do anything. Wasted my money and of course you won’t get your money back even if the app doesn’t work. Tired of apple letting crap apps on the App Store. ### 1/5 — ㅈ같음 *2021-10-29* 아무리 쓰레기 케이블을 연결해도 최적 상태의 충전기라고 함. 개쓰레기 그냥 퇴물 ### 1/5 — Incorrect results *2021-10-01, version 3.7* Incorrect results ### 1/5 — 垃圾 *2020-10-16, version 3.6* 垃圾 ### 1/5 — 明明用Apple 18w 充電，但是顯示6.5w充電！ *2019-11-06, version 3.3* 明明用Apple 18w幫iPhone 11 充電，但是顯示6.5w充電！ ### 1/5 — Pointless and misleading *2019-07-01, version 2.0* This app makes the false assertion that there is one “optimal” charging setup but fails to realize that there isn’t. Is optimal the fastest? But it stresses the battery and reduces its longevity? Is optimal the one that maximizes the number of times the battery can be charged over a phone’s lifetime? But that would be a slow charging setup. Is “optimal” done other unstated mysterious yardstick? Says who? All in all, this app is based on a very simplistic unstated assumption that gullible users who don’t know better will swallow. ## Most praised reviews (10 highest-rated) ### 5/5 — Great App *2025-03-13, version 4.2* The app has been extremely helpful. The information provided has been useful! ### 5/5 — 建议增加充电过程曲线或者数值显示 *2023-04-28* 首先感谢作者的开发维护，没有广告等杂乱更新。 近半年只更新了必要机型支持非常不错，但是其中使用过程中还是不太方便，建议增加充电过程曲线或者数值显示，这样会更直观的看到本机充电过程。谢谢ヾ(≧∇≦谢谢≧∇≦)ノ **Developer response:** Thank you so much for your thoughtful feedback and continued support! We truly appreciate your recognition of our ad-free experience and focused updates — that has always been an important principle for Mister Battery. Your suggestion about adding a charging curve or numerical data display during the charging process is an excellent idea. A more visual and detailed presentation would definitely make it easier to understand charging behavior at a glance. We’re actively considering enhancements like this to provide clearer and more intuitive insights in future updates. Thank you again for your encouragement and constructive suggestions — they help us make Mister Battery better with every version! 🔋 ### 5/5 — love hate relationship with speed of app *2022-09-16, version 3.9* it can be fast and it can be slow ### 5/5 — Apple MagSafe battery pack *2022-07-05, version 3.9* Can you add MagSafe battery pack data ? ### 5/5 — Only measure up to 18W *2022-01-05, version 3.9* On iPhone, only measures up to 18W, even though the charger was outputting 20W. ### 5/5 — 功能建议 *2021-12-21* 添加充电功率变化图或细化分类，添加总充电时长。 ### 5/5 — USB meter in an app! *2021-08-21, version 3.7* This app is basically a usb meter but in an app. Super helpful if you’re trying to find out the wattage of the charger and cable. ### 5/5 — good *2021-03-16, version 3.7* its very good app for test sharjer , thanks. ### 5/5 — 很好 *2021-01-21* 用这个测试了我几个充电头，感觉还是挺不错的，自己用也不是专业评测，大体上下个10%吧！省去了单独购买充电，电压，电阻测是器 **Developer response:** Hey 吃v刚才. Thanks for your feedback. Glad you like it! ### 5/5 — iPhone12 mini display size not good. *2020-12-27* Good app. Please modify display size at iPhone12 mini. Clicking buttons of top are very difficult. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
