One of the most common problems with smartphones is battery life and Android also suffers from this issue. Many of the smartphones running Android have short battery life although there was some improvement with the release of ICS (Android 4.0). There are quite a lot of battery apps for Android which can improve the battery life. We had already covered some of the best apps to improve battery on Android phones.
Deepsleep battery saver is yet another free app to reclaim your battery. Deepsleep battery saver constantly puts the device to deepsleep mode while screen off, this app takes battery management to next level.
During the deep sleep mode, Wi-Fi, 3G are turned off, background apps are stopped. When background apps are turned off, most apps are not working, including Facebook, Google Service like sync etc,. It then constantly wakes up in order to download email, sync Facebook status, etc,. It’s defined by deep sleep frequency and wake up duration. In advanced mode (Pro version), you can customize more parameters, including day/night settings, active period, screen timeout, sync strategy, ignored apps, etc,
There are 5 pre-defined profiles for available for selection: Gentle, Balance, Strong, Aggressive, Slumberer. They varies on frequency, duration and other settings. The former is less disruptive, but save less battery and vise versa. If you select the aggressive plans, your email delivery will be affected since sync works only after a long time, so based on your requirements you can select the profile.
