Will update soon! ### 3/5 — 所詮無料ですし *2014-05-20* 5%刻みでしか確認できないのはイマイチ。まあ所詮無料なのでそんなもんでしょう。 ### 2/5 — あまり使い道なし *2013-12-10* •自動と言いつつバックグラウンドでは動かないから実質手動。 •グラフの横軸が時間軸でないので、どのくらいの勢いで減っているのかわからない。 •残量表示が本体と一致しない というわけで、通常使用でのバッテリの減り具合を確認したかったのですが役に立ちませんでした。 ### 4/5 — いいですねー *2013-11-12* 結構いいと思います。 ただ、グラフを全画面で 表示できたらみやすくなるかな？と、思いました！ ### 2/5 — グラフが良い *2013-10-26* バッテリーの充電の様子がグラフに残るので、ポータブル電源の相性を見るのに良い。 1分ごとの記録というのは良いが、グラフが無駄に長くなりすぎるので、横方向を縮尺変更したい。●をつないだようなデザインはスペースを食うので、普通に線だけで良いのでは。その前に、5％ごとにしか記録できないのは厳しい。1分単位で記録しても、しばらくグラフは変化せず、無駄。 また、スクロールが任意の場所で止められないのが不便・・・見たい箇所を真ん中にできない。そして、現状ミスがあって、スクリーンショットで画像を残してつなげると、一回のスクロールごとに1目盛り失う。 別ページの時間とバッテリーのグラフは、どうも実用性が低いように思う。時間のグラフはもう少し目立たない色でないと、バッテリーの方が見づらい。 あと、時計表示の数字が、液晶の消えている部分まで下手に同色で表現してあるので見づらい。消えている部分はなくてもいいくらいだが、せめてもっと暗く(薄く)して欲しい。 ## Frequently asked questions about BatteryNow !
