Ampere vs AccuBattery Usage & Stats

Did you ever felt, that one Charger/USB cable set charges your device really fast and the other not? Now, you can prove this with Ampere. Measure the charging and discharging current of your battery. PRO features: - Widgets - Notification - Alerts on device - Alerts on Android Wear Not every device is supported because there are devices which lacks an appropriate measurement chip (or the interface) and they can not be supported at all. Please read the list of not supported phones at the end of the description. The app is not meant to be mA accurate. It is only good for evaluate which Charger/USB cable combo is working the best for you on the same device. ---- Please read also the FAQ: http://goo.gl/R8XgXX ---- Start the app and wait ca. 10 seconds ("measuring" is on the display). After this time, the charging or discharging current will be shown. The current depends on many things: - Charger (USB/AC/Wireless) - USB cable - Phone type - Current tasks running - Display brightness - WiFi state - GPS state Please don't use the readings on this app as concrete science. However, the readings are good enough to relatively measure how various chargers and USB cables fair on the same device. If the app shows 0mA all the time, please use the settings option "Old measurement method". You can force the app with it to use the old measurement interface, if the Lollipop device has at least one. Unfortunately some Samsung devices don't give correct (measured) values (e.g.: S5), just the maximum possible charging current with the actual USB cable/charger configuration. This is a firmware problem. ---- Background info: The app measures the charging/discharging current of the battery. If your phone is not connected to a charger, you see the discharging current which is negative. If you connect a charger then the current what the charger gives will be used to supply your phone and the remaining power will be charged into the battery. If your phone consumes 300 mA without a charger connected (-300mA on the display), then a 500 mA charger will charge your battery maximum with 200 mA current (200mA on display). ---- Technical info: The displayed current is an average value from 50 measurements minus the 10 upper values and the 10 lower values. The displayed current can be shaky or unstable or even zero which means, that the Android system provides unstable values. Every company uses different battery types and other hardware making it difficult to get accurate results about your charger. ---- LiPo batteries don't draw the maximum for the full time it takes to charge the phone. If your battery is charged almost full then the charging current will be much less as by lower battery levels. - A graph explaining LiPo charge stages: http://batteryuniversity.com/_img/content/ion1.jpg - Dave's (EEVBlog) LiPo Charging Tutorial: http://youtu.be/A6mKd5_-abk ---- Phones/ROMS compatible only with "Old measurement method" switched on and selected the right "Measurement interface": ➤ HTC One M7 / M8 ➤ LG G3 Phones/ROMS reported to be not working with this app: ➤ Galaxy Grand Prime - fortuna3gdtv ➤ Galaxy Note2 - t03g, t03gchn, t03gchnduos, t03gcmcc, t03gctc, t03gcuduos ➤ Galaxy S3 - d2att, d2spr, d2vmu ➤ Galaxy Tab4 7.0 - degas3g ➤ HTC Desire 510 - htc_a11ul8x26 ➤ HTC One S (ville), X (endeavoru), XL (evita) ➤ HTC Sensation 4G - pyramid Please do not give wrong rating, if your phone is one of the above. Not the app is wrong, but your phone does not support this kind of measurement yet. If the app doesn't work on your device with pre-Lollipop Android version, then please read the first and the second posts in this XDA developer forum thread: http://goo.gl/pZqJg8 . Please post your problem with screenshots in the XDA thread. Please read also the FAQ: http://goo.gl/R8XgXX

AccuBattery

AccuBattery displays battery usage information, and measures battery capacity (mAh) based on science. ❤ BATTERY HEALTH Batteries have a limited lifespan. Every time you charge your device, it wears out the battery, lowering its total capacity. - Use our charge alarm to remind you to unplug your charger. - Discover how much battery wear was endured during your charge session. 📊 BATTERY USE AccuBattery measures the actual battery usage using information from the battery charge controller. Battery usage per app is determined by combining these measurements with information on which app is in the foreground. Android calculates battery usage using pre-baked profiles that device manufacturers provide, like how much power the CPU uses. In practice however, these numbers tend to be highly inaccurate. - Monitor how much battery your device is using - Know how long you can use your device when it’s active or in standby mode - Find out how much power each app uses. - Check how often your device gets woken up from deep sleep. 🔌 CHARGE SPEED Use AccuBattery to find the fastest charger and USB cable for your device. Measure the charging current (in mA) to find out! - Check how fast your device is charging when the screen is on or off. - Know how long it takes to charge your phone and when it’s finished. HIGHLIGHTS - Measure real battery capacity (in mAh). - See how much wear your battery sustains with each charge session. - Look up the discharge speed and battery consumption per app. - Remaining charge time - know how long it takes before your battery is charged. - Remaining use time - know when you will run out of battery. - Screen on or screen off estimations. - Check the percentage of deep sleep, when the device is in standby mode. - Ongoing notification for real time battery statistics at a glance. 🏆 PRO FEATURES - Use Dark and AMOLED black themes to save energy. - Access to historical sessions older than 1 day. - Detailed battery statistics in notification. - No ads We're a small, independent app developer with a focus on quality and passion for battery statistics. AccuBattery doesn’t require access to privacy-sensitive information and doesn't make false claims. If you like the way we work, support us by upgrading to the Pro version.
