Accu​Battery

AccuBattery is a battery measurement software specifically designed for mobile devices. It not only monitors battery level in real time but also calculates actual battery capacity and generates corresponding analysis reports based on long-term measurements, helping users understand and improve battery usage. The software also measures the current charging speed and full charge time in real time and calculates the remaining battery life based on user usage intensity, meeting user needs. It also offers a dark mode to further conserve battery power. It is believed that using AccuBattery can further extend the battery life of your device.

Features of AccuBattery:

Understanding Battery Health: One of the core features is its ability to estimate battery capacity. Unlike standard readings, it measures the actual battery capacity (mAh) using data from charging sessions. This provides a more accurate picture of battery degradation over time. The app then uses this information to give you insights into your battery health.

Charge Monitoring & Alarms: AccuBattery provides the ability to set charge alarms. These alarms remind you to unplug your charger at a specific percentage, preventing overcharging and minimizing battery wear. The application also tracks battery wear during each charging session, giving you a clear understanding of the impact of your charging habits.

Detailed Usage Analysis: The tool meticulously tracks battery usage, providing a breakdown of which apps and processes consume the most power. This allows users to identify and address power-hungry applications, optimizing battery life and overall device performance. Users can see exactly how much power each app uses.

Real-time Statistics: Beyond historical data, the service provides real-time statistics on battery usage, including estimated remaining charge time and discharge speed. This information is invaluable for planning device usage and avoiding unexpected battery drain. All of this is presented in an easy to understand format.

Highlights of AccuBattery:

Degradation Tracking: The application provides a feature to monitor the level of battery degradation to know whether your current battery condition is really good or not.

Replacement Indicator: The application will measure the battery level, and if you encounter battery problems, you can consider replacing the battery to ensure the device is safe.

Overcharging Prevention: Many people today are overcharging their batteries, causing the charging situation to be overloaded. The application will help you by notifying you when you should unplug the charger to ensure battery health.

Cable/Adapter Insights: The application conducts analysis of charging cables and battery transmitters so that users can change or make more appropriate decisions to ensure battery life.

Time estimates and deep sleep tracking: AccuBattery calculates remaining charge time and use time based on recent activity. It also reports deep sleep percentage in standby, with an ongoing notification that shows live stats without opening the app. Therefore you can glance at the status while doing other tasks. These cues keep daily monitoring simple.

User Reviews of AccuBattery:

Very accurate with good information. Attractive UI. Has a nice, adjustable alarm that triggers when the charging battery reaches the charge amount that you set. If you only charge your battery usually only to 80%, it will extend your the life of your battery. I used this app on my last phone for 4 years and the battery was still in pretty good shape. Great app that really does work. It is worth the money for the pro version. I wish it showed battery temp and alert when it gets too high.

It is refreshing to find a battery app that doesn't make all sorts of extravagant claims about how it will radically increase the time I get from my battery, etc, etc. Instead, we get an idea, based on scientific research, for extending the life-span of the battery, a timer which lets you know when the battery has reached your chosen level of charge and a bunch of useful information and statistics about your battery and charger and even the cable you use with your charger. Great job, Dev/s!

Great app. It could only be improved if it actually stopped your phone from charging at the level you set. This may be impossible with the current (lol) technology. Edit: yeah, this is not possible even with the current android iteration. Been using it for years now. It keeps great data and helped me keep a an already used Samsung phone for about 4 years!

More than expected, even with unpaid version. An inordinate amount of battery information giving me better control of my devices. Without the ability to swap batteries, once they go, so does the device. This has given me an extension of my phones and tablets battery life without any noticeable effect on speed. Tweaking the alarm and the occasional shutdown of the app is well worth the effort. Try this one.

FAQs of AccuBattery:

Why is my estimated capacity above 100%?

The main reason is that many batteries actually start above their labeled design capacity. As the capacity will be reduced over time with usage there are some manufacturers that use larger batters to ensure an acceptable runtime after a few hundred cycles.Also, our capacity is an estimate, with more charge cycles the estimates will improve (charging a larger % will also be more accurate than charging a lower %). For the most accurate estimate please do a manual benchmark instead: https://accubattery.zendesk.com/hc/en-us/articles/213575425-How-to-benchmark-your-battery-healthLastly, there are many phones out there that just have good batteries. We have a Xperia Z that's over 3 years old, charged daily (most of the time to 100% instead of the recommended 80%) and it's still at 99% of its claimed capacity. We also have a Moto G 1st gen that's still at 97% after 1.5 years.

My phone doesn't have show notification categories (charge alarm, battery status, etc.)?

On some devices notification categories are hidden and you need to enable the following setting to make them visible in order to tweak AccuBattery's notification settings at the individual category/channel level:System settings > Notifications > Advanced Settings > Turn on "Manage notifications categories for each app" > Go to AccuBattery notifications > You can now turn individual categories on/off. Now you can for example hide the battery status notification while keeping the charge alarm notifications. 

Why does the current and voltage differ from the USB line measurements?

AccuBattery measures data at the battery level. A standard USB port delivers 5V and up to 2A of power to the phone, which you can measure on the USB lines, but this isn't delivered directly to the battery, as it requires a very specific voltage and current.This conversion is done in the phone's power management IC or battery controller, and we measure the data after this conversion.Not all power entering via the USB port is converted to charge - the device CPU, screen, DC-DC converter, etc, all use a bit of power. We measure only the actual charge, measuring on the USB line will always result in a too high wattage.QuickCharge, USB-C Power Delivery and related technologies supports higher voltages to enable higher charge speeds, but all this is converted down to 4.35V maximum before it enters the battery. You can see the actual battery voltage and charge current in AccuBattery's charging tab.

How to force stop the app before taking a bug report (only required if asked by support)?

1) Long tap on AccuBattery's icon on your homescreen, or long tap our persistent notification message and click on "app info" (or go to Android system settings > apps > AccuBattery). 2) Tap on 'force stop'.3) Click on the AccuBattery icon again to open it back up.

Summary:

Currently, the need to use work makes users use the phone often. However, this habit causes your device to decrease in life and wear out more. Most of your device’s capacity is not enough for a day’s work and entertainment activities. Therefore, to help users manage smartphone batteries, Accu Battery was born to serve users to manage and save battery capacity optimally. For those who work a lot on the phone, this application should be pre-installed for their phone to have the best experience.
