Help Best Battery Saver Apps?

Hello,

Can anyone recommend the best battery saver apps?

I really love Juice Defender, but it no longer works with the Lollipop Update on my Moto X. I think the main ways Juice Defender helps so much are that it disables wifi automatically based on location and it disables mobile data as soon as the screen is turned off. It is also highly customizable, and there is a paid version with no adds so I really like it, and it greatly increases by battery life.

Are there other apps with this level of functionality that has made a huge difference for me? I have heard of some of the others like Greenify or Battery Saver, but are they as good as Juice Def?

Thanks.
 
I've long since ditched Juice Defender for Green Power. They have almost all of the same settings, but the last update for JD was since before ICS. And Green Power is still being updated.
 
Battery Saver apps such as Juice Defender, DU Battery etc etc are ineffective at best, often actually using more power than they save.

The only 'battery saver' I know that is actually worthwhile is Greenify, which works differently than other battery savers. It should be used carefully and sparingly.

That said, I've never needed Greenify and don't even have it installed. I never use any battery saver.
 
Depends on how exactly it makes the battery savings. Green Power and Juice Defender actually do work. Without Green Power, I lose another 10-15hrs of standby time. Because Green Power and JD works by turning off mobile data and only enabling it in intermittent periods. We can both agree than mobile data turned on eats more battery than mobile data turned off. Basically though, they won't save any battery if you don't keep mobile data on.
 
Juice Defender is abandoned, partially because it was simply no good. I had a couple of links saved about it, one was a good test demonstration and explanation. I'll try to find them later.

As for switching off mobile data, doing so could save a bit, but only if you're willing to be disconnected from the internet. I wouldn't want to. If I have WiFi the phone turns mobile data off. If I don't have WiFi, I want mobile data on.
 
Thanks I will try Green Power. Perhaps it could work in tandem with Greenify since they work differently? I strongly disagree that an app like Juice Defender doesn't work, it literally doubled my battery life instantly. It's true you can manually do all the things most of these apps do, but that would be a royal pain in the ass. Manually disable mobile data and re enable it every time I turn the screen off and on? Not gonna work...
 
And yes I would rather disconnect from the Internet when I am not using my phone rather than get instant notifications from 100 apps that kill the battery and keep me glued to my phone when I don't need to be
 
Well, I don't manually switch anything. The phone handles it by default.

I don't have to stay glued to the phone or listen to notifications from 100 apps all night. The phone takes care of itself xand notifications I don't want to hear at night are auto-silenced on a schedule.

And my battery lasts pretty well.

One of those links about Juice Defender I couldn't find and the other is so old it's no good. A shame, it was a really good test and explanation of why JD and similar apps just don't work. I'll see what else I can find.

Juice Defender and similar apps doesn't really work because it only extends the standby time. It won't change the battery usage if you are actively using the phone. So for someone who is on their phone all the time typing, playing or whatsoever, JD, GP, or whatever battery saver apps are just a waste of memory space or money. They work by turning your internet connections off, then reconnecting them only after a given interval (say every hour), or when you use the phone (detected by unlocking the screen, or having it turned on). Basically, they're not saving power when the phone is being used. It's no different from manually turning off the data/wifi before locking the phone, and turning it on again after unlocking. Only automated. With interval activations of internet even if the phone is not being used.

Thing is, some people just want their standby times increased. In my case, I can only check the phone in between work activities, which may last 4-6hrs. Instead of having the phone's mobile data active for the entire 6hrs, using up battery and decreasing standby time, with GreenPower, during the 6hrs, mobile data has only been active for 12min (1min active data connection every 30min). The battery usage of 6hr mobile data active and 12min active is quite large. So yes, it does work, but only in specific scenarios. Basically, the less you use your phone, the more battery is saved. So yeah, these kinds of apps can be said be work, and not work at the same time.
 
In theory, what you say sounds right. I completely agree that unless the phone is just sitting no battery saver can do anything about saving power. But in practice, even sitting there Juice Defender and similar apps use a considerable amount of of power doing the monitoring processes and other tasks needed to do the job. IOW, the more tasks JD was asked to do to save power, the more power JD used itself. As I remember, in the tests (that I used to have a link for) net savings results varied from a net plus to a net negative, depending of course, on the particular setup and other conditions, such a strength of cell signal, sync frequency, etc. I really wish I could still pull up that test, it was excellent.

The overall verdict was that in almost all situations you would be better off skipping Juice Defender and just setup the phone correctly for your use habits, like not running an excessive number of mail passes, using WiFi instead of mobile data, obvious stuff like that.

For your particular case, if it doesn't matter that you're disconnected from the internet during certain times maybe Juice Defender would save a little bit of power. For most users probably not. But the thing is smartphones are designed with 24/7 connectivity in mind and that's how most people use them. I've never used my phone in a way where a battery saver would be useful.

Android is finally getting a battery saver, that is, something you could consider to be a battery saver app rather than built-in system optimizations. Doze. Which will do things similar to many common battery savers like JD. No doubt it will be much better engineered than flawed, poorly done apps like JD. Notice that Google isn't making ridiculous power saving claims for it and that it only will save power while the phone is not in use.
