    How long does it take before AccuBattery's stats are in the right ballpark? The reason I ask is because I have just installed a replacement battery (from a reputable store, but an unknown brand) in my phone and I am using AccuBattery to make sure that the capacity is approximately what it said in the listing. I deleted AccuBattery's data immediately after installing the new battery. Then I charged it from 29% to 99%. At 80%, AccuBattery said that the health was 53%. Now at 99% it says that it is 63%. However, the capacity estimate in the charging tab was jumping up and down all over the place as the battery was charging and is now at just over 2,500 mAh, which is about 90% of the expected capacity. I didn't get this kind of way off readings and wild fluctuations on previous occasions when I installed batteries bought from the phone manufacturer's official spares dealers. Those batteries consistently showed capacity right from the beginning, according to AccuBattery, that was a little way short of the nominal capacity.

    Never.
    That is the timeline to expect a battery app to give an accurate reading of battery health.

    They just don't.

    In other words, do not rely upon any app to say if a battery is good.

    Literally, I have had battery apps tell me that a battery was in good health when it had already ballooned up to the point that the back would not stay on the device.

    Eventually, it grew so large that the battery contacts could no longer maintain connection, but if I held it together very tightly to keep the battery connected, the apps all said that the battery was just fine.

    Is the replacement battery the same capacity as the original battery or is it a higher? Since it's a third-party, off brand battery that might affect how the AccuBattery app detects and monitors it.
    When I was reading through the feature list of a different app, the AIDA64 hardware/software assessment utility, there was a reference that might be pertinent to this situation:
    - Battery capacity can only be reported for factory default batteries. If the battery was replaced with an extended capacity battery, neither Android or AIDA64 will be able to detect the new capacity.

    I'm assuming that there's an issue involving a phone's existing power management circuitry and a battery's circuitry that will probably apply to how AccuBattery functions too.
    If you start up the AccuBattery app, tap on the 'Charging' tab at the bottom, scroll to the bottom and tap on the Set Design Capacity link, that should show the battery's capacity rating. If not, manually enter it. Then wait a few days, it typically takes several charge cycles for any reliable numbers to get collected and assessed. But again, is this new battery the same capacity as the original?

Designed to keep your battery in the best shape you can – AndroidHeadlines   Accu​Battery protects battery health
, 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. Scientific research shows that battery lifespan can be extended up to 200%
, when you charge your device to only 80%
.   - Use our charge alarm
to prolong your battery lifespan. - Discover how much battery wear
was endured during your charge session.   BATTERY USE
  Accu​Battery 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 Accu​Battery 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)
. - Use the charge alarm
to prolong battery lifespan. - 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
