Perfect Battery Charging

Android’s default GPS feature is useful if you use a lot of location tracking apps – like Google Maps or business finding apps. Thankfully, Google realized that GPS wasn’t very battery efficient, which is why they created a GPS mode that uses less battery life and implemented it into Android 4.4.
This battery saving GPS mode won’t completely take away your location-finding features, but it will use fewer reference points to find your location.
In all likelihood, your location will still be fairly accurate, just not as accurate or as quick-to-respond as the default GPS mode. To enable this mode in Android 4.4 KitKat, go to Settings > Location > Mode and then check the box beside Battery Saving.
If you’re in a situation where you need very precise map tracking, then you can easily disable this mode. Until then, enjoy your longer battery life.
"Not OK, Google"
On the one hand, be thankful your phone is such a good listener. On the other hand, it's not worth killing your battery life.
Thanks to the new, persistent Hotword detection, you can say "OK, Google" from any home screen (or within Google Now) to prompt Google Search and Voice Actions. That means, however, that your phone is always listening, waiting for you to say those magic words.

If you turn sync off you don't receive e-mail notifications.Using different charger won't break the battery it's just gonna charge your phone way too slower than its original charger.If you don't root your android phone, what's the point of using an android phone, just buy an iPhone.Memory managers don't work, they use ram and always run in background.Most of the time they don't even clear the ram.Battery manager apps are useless.They always run in background and use ram like memory managers.I don't believe that they help with battery life.If you want your phone's battery lasts longer in daily usage; Things you can do : Lower the brightness (not auto), turn sync off (if you don't use e-mail), wi-fi definitely off if not used, turn power saving mode on (at least tick cpu option). and of course gps/bt always off.
Apart from phone's settings things you can do : Putting your phone in airplane mode when you're going to bed (you don't have to use an auto app for this, remember they use ram), after putting your phone in airplane mode set its CPU frequency to something like 500-600 MHz.You don't need your phone to be fast while you're sleeping.
And definitely root your phone.Removing useless samsung apps and changing them with better apps that do the same work with less usage of the hardware will definitely speed up your phone.You're not just gonna remove some apps, if rooted, you should block apps that run at boot (except fb,whatsapp,foursquare etc. if you wanna get notification).
And no 3rd party apps that affects your UI completely (like launchers, lockscreens).Changing your launcher won't speed up your phone since it's based on touchwiz it's always gonna be a little bit slow in terms of waking up especially.They're just gonna use your ram and always run in background.
Anyway, this is how i use my phone.It lasts more than 2 days if I just use it for messaging, calling and mild internet use.But of course if you're gaming (i do) nothing's gonna stop it from draining Max 8 hours (which is actually good for this phone)

Isn't frequency scalable? (I thought this happens without the 3rd party apps...?). As I understand, the CPU goes to lower frequency mode automatically, since this is probably a kernel feature. Why do u need to set it specifically every night?
