Uninstaller and reinstalled; where the time should have been read empty and the percentage left froze at 37%. Hopefully it works now...

I've been pleasantly surprised as the app continues to function properly on new Android versions (currently 7.0) years after its most recent update. Follow directions = profit.

It's not updated, it still does the job for me.

Widget constantly showing incorrect battery percentage, whole point of the widget is to see info quickly no point in this widget if I need to tap on it then navigate to the proper screen to see the correct info. If this gets fixed I'll update my review.

K70%
by K####:

This is the one app I've been using since first getting Android in 2010, it's the one I always install first. But how about a refresh to the widget? The glassy look is getting older and older looking in the days of Material this and flat UI that.

Doesn't report all app usage. Numbers add up to 85‰ of usage not 100%

by M####:

Had to uninstall as the app used 10 MB of mobile data in 7 days. What is it using that for anyway? Very suspicious!

Z70%
by Z####:

This used to be a five star review, but then I realized that the app wants permissions to look at my files and my calls. There is no reason a battery app should legitimately need to do those spyware things. Do not install.

G70%
by G####:

This widget, even after fully analyzing my battery, is a lot more accurate than the other apps I've tried. It also looks nice and has quite a few options. I do have to agree with one of the other reviewers though. I didn't verify his claim, but is it actually sending data weekly? If so, could you please let us know why? There shouldn't be a need for it.

This app is fantastic and very accurate. Would like to be able to select a larger number readout for the percentage of battery left because of my failing eyesight and that you could turn the notifications on or off independently (percent or pull down). Thanks for a useful tool!

This widget takes a few days to get it accurate for on the readings, but I love the way it will tell me 'about' how much battery I have left - in TIME rather than in a percentage. Both myself, my husband, and my son use it on our tablets (Samsung 10.1 Tab, Motorola Zoom, Asus TF101, and Asus TF300) - it works as advertised on all devices - plus I have it on my new Galaxy Nexus. LOVE this app!! (and the price is right! ;-)

Have used +3yrs.... Worth the wait for calibration. Has MANY visual + functonal prefs. Shows est %,time...etc (up to 3). Gives app usage % history. MORE ACCURATE than my system batt. Would def pay for this! ~ [HTC Incred 2]

Love the app! Many useful features. Battery calibration for extended battery. Only thing missing is ICS support. App acts really weird and doesn't work well on 4.0. Was great on gingerbread.

C70%
by C####:

This widget is outstanding and very customizable. I use it constantly. My only complaint is the accuracy. Could you do an average of 3 separate passes during calibration to get a better time estimate? I feel like that is all this needs to be perfect.

T70%
by T####:

my system battery meter drops 20% twice in a full charge, i can not fix, (yes batterystats.bin has been calibrated)... THIS is the only app I've found that does its own calibration, and WORKS GREAT!! i now know just how much power is really left, and when to put phone on charger... worth donation, and you get a colored changing status bar icon, a feature worth paying for in it self... i think a graph option on the paid version would be cool, (on the main screen)...

Needs an update already. New graphics, ui overhaul, new features. Once I see active Dev, 5 stars and buying full version. Until then free version and 4 stars it is.

Good Apps.

Z70%
by Z####:

I just got an extended battery for my Motorola phone, and the system battery meter is based on the hard-coded stock battery capacity, so it's useless now (says 1% when the battery still has over half a charge). I was hoping that this app's voltage based estimate would work better but it's actually worse than the system one after doing a full charge and discharge cycle to calibrate it! Fortunately I found another app with working voltage based estimation.

It was working beautifully on all my S3 and Note 3. Until today. It just stopped updating. Reset widget, but now its says please wait, and has for the past 3 hours. Took 5 down to 2.

Boring

Q70%
by Q####:

I just uninstalled this app after finding it had used 30MB data in a week. I see that excessive data usage is listed as a bug fixed in the newest version, but I would still like to know what kind of data was being sent. I never opened the app in that time, and what does a battery app need with background Internet anyway? Please clarify why this app needs network connectivity. After my previous experience, I am wary of trying it again.

R70%
by R####:

Tried other battery apps but always come back to this one. Gives you a really accurate idea of how much TIME and not just a percentage of power you have left. No frills, just what you need. Edit: the latest updates are ruining this app. Took 5 star down to 3. Please fix Edit: dev fix in one day! Thank you, here's your 2 stars.

D70%
by D####:

I prefer the accurate 'time til dead' data to 'constant percentage', thus the 4 stars. The Fahrenheit on the widget NEVER matches with the Fahrenheit within the battery info section, however. This makes me doubt the app's veracity. Can you fix this?
