Description by Petr Nálevka (Urbandroid) (from Google Play)
Official Doze mode is only for Marshmallow, but Dozzzer brings this powerful battery saving feature to all Androids. Yes, even to your Gingerbread granny!

How it works?
Internet is one of the biggest battery drainers. Dozzzer takes care to cut down connectivity whenever you are away from phone.

Highly configurable

Dozzzer is highly configurable. Go for maximum battery saving or save but get all messages on time.
Eager - activates right after turning screen off
Medium - after 5 minutes of idle, messages may be delayed by ~7 minutes
Lazy - after 10 minutes of idle, messages may be delayed by ~2 minutes

Why we ask for VPN?

Android does not allow controlling mobile data directly on Lollipop and later. We rather use a VPN as a firewall. The VPN is strictly local and does NOT cause any security risks!
The good thing? VPN allows to exclude apps (e.g. Skype or Hangouts) from Doze (Lollipop only).

Dozzzer makes sense even on Marshmallow. With eager settings you can get even more out of your battery.

Recent changes:
1.3
- Ability to keep Dozzzer running when on charger
- Fix for a bug when VPN stayed enabled after a phone call
1.2
- Sleep as Android integration, VPN simulator and few fixes
- Czech localization
1.1

Comments on Dozzzer for Android

★★★★★ Techie Prajwal P.P · Mar 2, 2017
Works perfectly in Gingerbread.... I thank your team... Good work... Often app developers create apps without thinking of previous android versions, but you didn't do it 👏👏👏. I am using Android Gingerbread and have faced several problems when downloading apps because often it won't work with my Gingerbread.... Thanku once again 👍👏👏
★★★★★ Ashley Bolton · Dec 30, 2016
It actually works! Finally! A battery saving app that ACTUALLY does what it says it does!! My battery life has increased exponentially since downloading this app. The best part is, I don't have to do anything for Dozzzer to work its magic. It runs in the background, increasing my android device's battery life! There's a noticeable difference in my battery drainage since installing this app. I would highly recommend it to any Android user.
★★☆☆☆ Vinicius Thedim · Sep 21, 2017
App stops Wi-Fi connections on versions previous to marshmallow what leads to problems on VOIP activities, such as WhatsApp voice calls. It could solve this problem using root access for app exclusion. Suggestion. Please make adjustable time for activation after screen off. Many users need shorter time such as 1 minute. App is no more being maintained and there is no updates for a long time
★☆☆☆☆ John Mallah · Jul 30, 2017
Disconnects my VPN ultimately giving me a choice between my VPN or Dozzzer. My VPN wins.
★★☆☆☆ El Gand · Aug 19, 2017
S7 Edge. Only work at the first time I try. I sent a message for my other mobile nothing notification I think the data is off but then not work anymore. When screen off notification always busy and VPN must be setting manual again next again.
