Battery Log

It's REALLY useful, appart from the battery percentage in the corner, the function to log the battery's changes is incredible. For the past 2 years I'v activated the logging on all my devices. It does not uses storage, ram or cpu and you get some nifty graphs to look at.

Great app, very helpful to have a list of disconnections from the charger as I have been waking up multiple times in the night with no recollection of it happening. This app gives me the exact time when I have been waking up, taking my phone off charge, then putting it back on charge when I went to sleep.

This app is very useful on monitoring the behavior of your phone's battery. I hope yhe developers continue to update this. I need this on marshmallow version please.

The battery temperature never changes from 23.7. Its still pretty good app, but please allow setting the interval to record and perhaps allow choosing what data from sensors to record. Also- why a laptop on the icon?

Just one issue. How do I change the colours of the battery percentage icon in the notifications bar?

Really? Everyone should have this!

Not working properly it time mi 4

Worked great before. After update to Nougat, it doesn't work. Please fix. I love this app.

very good app. simple amd easy to use.. able to export to db and excel.. dang... nice

Won't log anything on my nexus 4 nor my note 5

Useful to log battery level, temp, voltage, time, status and export them as CSV file

Highly useful tool and works under Marshmallow updates.

I don't know, my battery-damage-o-phobia always make me feel anxious about my battery temperature. Thanks to this app, I can now take a closer look at my battery temperature when charging, in my pocket or, lets just say anytime. The only thing I find needing improvement is the graph.

Works great and comes with various settings. You can also export battery level logs to a file. No annoying ads. Thank you for developing this free app!

I am using this app for one month and found it very useful than other similar apps. But one problem that is with all battery graph logging apps plagues this one too. When the phone is charged for the first time after installing this app, there wouldn't be any problems, but from the second charge onwards, this app consumes some cpu while charging causing heating. I think it uses cpu to build the graph. Most of the battery graph logging apps have this problem. I use an app called cpustats to monitor cpu load.

Learned a lot on how best to manage my cellphone usage.

So it logs when battery is being used and when being charged or discharged no help to me just what to know if battery is to old and I should replace or upgrade battery will delete apparently

No guff, just nice and simple and light weight. All the other battery management apps were pigs and didn't tell me much. This collects all the days and presents it cleanly. Nice work!

This app is great for monitoring the accurate percentage change time for the battery. Thanks for making this fantasticly helpful app.

This is the app i was looking for, i need a battery log for my usage analysis, but why did this app selfclose sometime ?

Thank you so much dear..

This is quite good app to get every moment info about battery. I have given it full marks...

Won't log anything on my nexus 4

Simple and easy to use. Fonts on the chart are too small on galaxy s4.

Simple and functional. The export feature is a great addition.

I guarantee you won't find better

Lightweight app, uses very little memory, and works great on Android Marshmallow!

Nice app

Great app, easy too use, simple, but extremely practical. Now I can track my battery's performance continuously, not only since the last charging, and see if it started to lose capacity. And since it also has the feature to show the battery percentage on the notification bar, I use it also instead of the battery bot app. The app is minimal, so it doesn't use much resources itself. I highly recommend it!

Awesome app for monitoring battery but sometimes it just pause mainly after a heavy game

It would be nice to have the option to change the time of each percent increment to the amount of time in minutes + seconds it took to change instead of the actual time of day it went from say 98% to 97%. That way you could at a glance know how many min/sec it took to charge/discharge.

This is the app i was looking for, i need a battery log for my usage analysis, but why did this app selfclose sometime ?

very detail info about battery usage!!!

Very nice I love it

It gives a nice graph with a constant time scale. The battery chart that is built into the OS is nice but it is hard to compare today to yesterday because the chart has a variable time scale. This app allows you to keep long-term records of charge and discharge cycles for comparison. You can finally answer the question "did my phone die faster today?" or does this charger work better than that charger. The app doesn't appear to use much battery itself.

App does not log continuously. Stops after sometime. Works fine on S3 n HTC DHD. Fix it I will give 5 stars.

Simple app and does what its supposed to do, without any fancy graphics. Thanks.

Usefull app for checking died batteries

Do what it says
