JuicePlotter

★★★★★ Great app, but needs a updated. This is an amazing app, it works great, but needs a rehaul for newer versions of android. It works hit and miss on ICS and JellyBean, but is very laggy and not very optimised in terms of viewing statistic history.

★★★★★ Great app! Keeps track of your Android device's battery voltage and battery level readings to get the best idea of what kind of battery life to expect. Although the app could use an update as well as the icon to match JuiceDefender.

★★★★★ No time at bottom of graph anymore Love this app! Lets you see how many hours your battery lasts under different usage. Unfortunately, one of the recent updates removed the hour and minute at the bottom of the %/time graph on my S3. Can you re-add that?

★★☆☆☆ Getting bad. The best battery graph app on the market. But Y U NO UPDATE IT !!! It is really slow on my Galaxy S III. Please fix this issue.

★★☆☆☆ Don't bother The graph is very pretty, but interpreting the results is impossible as there is nothing to explain what the colours mean or what exactly is causing a sudden spike in battery usage. I also couldn't figure out how to find how long until the battery is drained at first, which is the main reason the app appealed to me. Turns out you have to tap the Help button & it shows up on the box that comes up. Which is hardly the obvious option for this feature & I totally missed it at first, especially as its crammed in between the help options & links to promote the app & give feedback. Oh & the estimate was waaaaaay off. As for the Help options themselves, the FAQ leads to a broken link, & the Help to a webpage giving a general overview of the apps features. Neither of these pages was formatted for phones & a link is a poor choice for something like this as it's no help if the person is offline.

★★☆☆☆ Used to be good... Not working on latest android 4.1.1 keeps force closing Not been updated in an age! Pity, really liked this app...

★★☆☆☆ Nexus 7 Force close on my nexus 7 stops working.. Works great on my samsung S3 though.. Hasn't had an update for a yr and half..lease update...
