Advanced Battery Calibrator

I think the app is great and does what it says, but last update wanted permission to access my home network and location. For a program that has only the function of calibration of the battery there is no need to invade privacy. Used to love the app. Sadly had to uninstall.

This app really saved me! I couldn't go through a whole day with my battery, even wiping the cache and calibrating it with other apps. So before I just went ahead and purchased another battery I give this app a chance and voila! Fixed my crazy battery drain issues. Thanks. ????

It does nothing at all, all you have to do is 1. Discharge your phone fully until it turns itself off. 2. Turn it on again and let it turn itself off. 3. Plug your phone into a charger and, without turning it on, let it charge until the screen or Led indicator says 100%. 4. Then turn on your phone

Edit: Being sceptical with this app was justified. It did improve my battery performance, but it lasted only untill second charging. After that, it is the same song again. But ok, probably we should be also conscious enough that weared-out batteries can't be miraculously repaired.

SPAMMER!! Installed it yesterday to give it a try and have been slammed with pop-up installers since. I try to write a text, make a Twitter comment, etc, and all of a sudden, there's a pop-up installer for a game associated with them. I don't mind them wanting support for their work, but this is no better than a virus! I can't tell after one use how good this or any app is (being that I'm not a fool and all), and their initial suggested "app install of support" had no background or info about it, so...

No evidence that it worked. Was looking to get the equivalent mAh of this battery. Being two years old, it has deteriorated. Would be great if you provided some diagnostic information instead of just voltage and percentage... And get those fake progress bars out of here, every dev knows what they are really for...

The same app under different names, littering the play store, claiming to do things they can't possibly do. Don't be fooled, they only exist to generate ad revenue and do absolutely nothing.

Actually don't know yet. Asked me for review before I could evaluate. Never understood why developers did that.

Just found out this app is fake and yes people it goes by a different name their are 3 names for it don't down load as it gives ur phone viruses

I was skeptical of this app from the sketchy ad at the start. I was impressed as it fixed my battery issue. I was stuck at 70% charging and this fixed it.

This is the first time I've actually seen an app that calibrates the battery yet any kind of app to colorize anything so it's a first for me I like it it's very effective and it's awesome thank you thank you guys for working hard to bring this free software which works like a paid version thank

Its incredible tool. It brought back my dead battery into life! How it fixed still confusing me?

Un program fake. Nu ajuta cu nimic. Bateria tine exact ca si înainte de calibrare.

This app is incredible, it saved my phone battery that was lasting 4 to 9 hours l max and discharging on standby at a scary rate. Having tried everything, AND I MEAN EVERYTHING (Full factory reset, greenify, sent phone to htc). Since running this my phone battery is on 40% after 1.5 days usage! Incredible

This app really worked on my nexus 7. I was thinking to replace the battery but after trying this app my nexus 7 can hold lots of battery charges. Great app highly recommended.

My mobile would shut down even when battery was 50% charged. After calibration it's working fine. Good job.

Terrible app, full of adds, only runs with Internet connection. Does nothing

Brand new battery. Said I had to calibrate b4 using. Did. Notice no difference. U keep asking for 5 stars......I dont think so!

No way of knowing if it works as tablet battery charges at a rate of 5-10% per day and I'm not waiting upto 3 weeks for a full charge to find out. Bummer

Fixed up my draining phone! Kudos!!!

Works great! Phone kept crashing due to battery issues and it helped.

The app claims to calibrate but does not report battery status. Tried it several times and served no purpose

It does actually worked! Suffered from random shutdown at 30% n now it's solved!

It shows Battery status as charging when it is not connected to charger. Also it doesn't show capacity of battery in mah i.e. 3200mah.

Nice job! Keep improving on a SLOW but METHODICAL basis, and your users will run to you... thank you for your work! Cheers

This app is really solve my phone battery issues... Thx for hard work and to all team that make this great app.

Battery % was dropping too slow at first and way too fast when low, this should make drop rate more even

Did wonders for my 5yr old kindle fire HD, this really saved my device from the junk bin.

It's great, it detects if your smartphone has root or dosent, and it works hard too ajust to calibrat you're type of cell. Thanks to all that made this app!

So far so good. Give things a few days to see how the battery performs.

Why u want star not verifying ur app? After using ur app then I comments u.

I'm going to try it out and get back to you see if it fix my issue

I don't know if it's fixed the spontaneous shutdown problem on my Galaxy S4 yet.

This app need for any more details to user.this is verey basicly

This app seems an excellent device for keeping cell phone battery in top condition. Use the companion app to Max battery condition.

Couldn't get beyond the "calibration" step. Installed, uninstalle, re-uninstalled... Still no luck. Bummer.

I have used this app several times to calibrate the battery. Sure saves $$ in buying a new battery.

After using app, screen time went from 3.5hrs to 2.5... Terrible.

My battery restarts my phone and has a charging issue but now the charging issue is gone

Do not give this root access, it will send your data to china
