バッテリーステータスを取得して、より頻繁に、またはAC電源/スリープ解除時に更新します
厄介な問題は、upowerがバッテリーの状態を更新するのに数分以上かかることです（この問題は この投稿 に似ていますが、ラップトップの詳細を提供します）。つまり、ラップトップを休止状態から復帰させると、数分間間違ったバッテリーパーセンテージが表示され、充電器を接続してもバッテリーアイコンはそのことを示しません（ただし、ハードウェアの充電ランプは点灯します）。それ以外の場合、更新時間は気にしません。
奇妙なことに、充電器のプラグを抜くと、アイコンがすぐに更新されます。 ウェイクアップ時に更新する一時的な解決策 を思い付きましたが、動作する場合も動作しない場合もありますが、適切な修正が必要なようです。 Acer Aspire E5-575G-53VGでUbuntu 16.04を実行します。
acpiは常に正しいバッテリーのパーセンテージとステータスを表示します。 Sudo service upower restartは、upowerのバッテリーステータスを強制的に更新します。

私が気づいたのは、充電器が差し込まれたとき、バッテリーの状態はまだdischargingです。ただし、/org/freedesktop/UPower/devices/line_power_ACADはonlineを正しく報告します。この問題の助けをいただければ幸いです。 KDEでこの問題が発生したことは覚えていません。
以前のプロジェクトの1つで作業しているときに、Unityの電源インジケーターには、明らかにイベント駆動型の更新遅延があり、UPowerデーモンが原因であることがわかりました。これは、UPowerデーモンを介して一定の精度でバッテリー使用量を監視しようとするカスタムスクリプトの邪魔になります。ただし、UPowerサービスには、その情報を更新/更新するための呼び出しがあります。以下のスクリプトは、そのdbus呼び出しを利用しています。スクリプトは、できれば~/binフォルダーにコピーしてファイルとして保存します。
使い方は非常に簡単です：./update_battery.py <SECONDS>、ここで<SECONDS>は情報を更新する頻度です。明らかに、非常に頻繁に更新するとリソースの使用量が増えることに留意する必要があります。そのため、たとえば3〜10秒など、ある程度賢明なものをお勧めします。

Sergiyの答えはうまくいきましたが、それがマイクロスタッターのパフォーマンスの問題を引き起こしていました。より効率的になるように修正しました。
まず、update-battery.pyを変更してスリープループを削除しました。

次に、5秒ごとにupdate-battery.pyを呼び出す個別のbashスクリプトを作成しましたが、必要な場合にのみ呼び出します。これをkeep-battery-updatedと呼び、スタートアップスクリプトとして追加しました。
#!/bin/bash
#
# @version 1.0
# @script keep-battery-updated
# @description keeps the battery status updated
#
##
while sleep 5; do
badbattery=$(upower -i /org/freedesktop/UPower/devices/battery_BAT0 | grep state: | cut -d ':' -f 2 | xargs)
case $badbattery in

badbattery="Discharging"

goodbattery=$(acpi -V | grep Battery | sed -n 1p | cut -d ':' -f 2 | cut -d ',' -f 1 | xargs)
if [ $badbattery != $goodbattery ]; then
python3 /usr/local/bin/update-battery.py
fi
done
現在、バッテリーは5秒ごとに更新されており、目立ったパフォーマンスの問題はありません
