Stay away, paid to remove ads and I am still getting hit with annoying ads constantly when I open it. Does not work very well either. Sent dev 2 emails and they don't reply so I will be writing a complaint.

Great app. Stability is much better now. One request, please add an option for a 12-hour clock on the lock screen boost. Currently it only shows time in a 24-hour format

Q70%
by Q####:

Like the set up. But it needs to force close apps also to prolong battery life.

Android 5.1, Lenovo p70 - constantly crashing. :-(, edit: Jan. 2017 it seems to work (at least it is not crashing anymore)

This is phone number 4 that I have installed this app. Wouldn't think of using any other

K70%
by K####:

Not worth 9.99 to remove ads when other apps do it FREE and are more optimal

K70%
by K####:

Paid $9.99 to remove adds but it still has adds. DO NOT WASTE YOUR MONEY.

by K####:

Пробуем. Wifi вроде отключает. Передачу данных нет. В белый список можно внести не только одну программу. Но срабатывает это белый список, как я понял из туториала в программе, только на ту программу, которая в данный момент на переднем плане на экране. Если свернуть ее, то эффекта не будет, судя по описанию. Сколько сэкономила программа заряда батареи не показывает. Наблюдаем.

P70%
by P####:

I was having difficulty determing, whether problem I had was battery or the Defender. Tests so far have shown that the NEW battery has been Truly Supported at a level of 28% & 21 % charge remaining. Recharge times to 100% have been wonderful at 1hr 36 mins. It's 8th to look like that it's very difficult to manage a failing battery when you can't predict when it will give you false information. It still has a healthy five

by V####:

On 6/22/2015 I paid $9.99 (ouch!) to remove ads and I still have them. I've emailed the developers numerous times about it, but the only response I've received so far is their standard reply that they've received the email and someone would get back to me soon. As for the app itself, I have no complaints. It works the way it's supposed to. However, my phone has a setting where wifi turns off when the screen is asleep, so I don't really need an app to do what my phone can do.

by K####:

I still manage to keep comeing back. Iv been through Alot of phones and alot of apps. This app here has saved me from alot of grief.

by V####:

Don't get why you don't give a choice between Farenheight or Celsius like all other apps. Give that option and you get 5 stars.

My android phone runs android 6 and this is certainly the best battery saver I've tried so far. Well done to all who developed it.

goodjob,but im still disapointed

E70%
by E####:

I used this app for years and loved it. But the release of Android 5 seems to have caught them completely flat-footed. Now it's useless. It didn't disable data connections, it doesn't prolong battery life. It won't even stay in my notification tray like when it's on. Avoid.

J70%
by J####:

Pretty good app. Some updates are in good shape but some do not. Still using it because others will not give kind reliabiliti like defender.

N70%
by N####:

New update feels like battery draining more and plus charging takes forever it was way quicker before

M70%
by M####:

It says it ends them but as soon as the app closes they open back up.

Save my battery phone was getting hot not now
