[Galaxy Note 3 General] thetitanium:
Well, Saving your phone's battery without compromising your phone's performance will be a little difficult for everyone. Everyone nowadays prefer phones which can last them for atleast a day. But what if we could extend our phone's battery life to 1.5 days or 2 days without compromising the power of your phone?

Yup. That's possible. I've been experimenting with my Note III SM-N900 [Indian Exynos Model]. I did it for almost like 6 months. My aim was to maximize my phone's battery life. And finally I found it. I wanna share all my results and the secret tips to save that last precious drop of your battery juice!

[NOTE: [Please keep in mind that I own a Exynos Model, i.e, SM-N900 and made all the customization on this model only. Many methods explained herein might not work for you.]]

:victory:

So, first a few words on my phone's history:

When I first got my brave and good looking Note 3, I was on 7th heaven. I got Android 4.3 Jellybean onboard. I used to get 2 days of unparalleled battery life. Smooth UI. But, very few customization. Previously I used to own a Galaxy SII i9100G. It had a great potential and till date is considered as the most selling Galaxy Variant. But, still I was happy. Then came the wave of KitKat 4.4.2. Guys, you won't believe, I spent weeks in the dilemma of the fact - Should I root or not root. Should I first update and then root? Should I root and then update? I was going crazy.

:confused::confused::confused::confused:

But then I decided. No, I should first update via OTA and then root my phone. And then, I did it. But soon I realised that I did a wrong thing. I experienced very, very poor battery life. With 3G on and screen time of 3-4 hrs, my phone used to die. But then I thoguht, there's still hope. Thus, I spend a lot of days into finding the best customisation for improving the battery life. And after 6 months, now I finally got the best battery life.

Guys, another thing I would like to say here is that, there was a very good article on saving battery life before, made by stanley08. [READ IT HERE].

STEPS TO MAXIMIZE YOUR BATTERY LIFE

1. Kernel Customisations:

Well, as you all know, kernel is the thing that sits between your software and hardware. Doing optimal changes to it is the best way out there to save battery. First of all currently there are two best kernels out there. halaszk and pekaka. Both are absolutely amazing kernels and I found halaszk to offer a greater number of modifications. But for everyday use I use pekaka now. On the top, it doesn't matter that much. So, let's get started.

First of all, halaszk kernel comes with a very powerful tool called synapse. It allows you to individually set the frequencies, voltages, GPU speed etc.

If you wanna use pekaka, then use an app such as Trickster MOD app from PlayStore.

The main part comes now:

1. Reduce all A15 cores to -25 mv each.

2. Reduce all A7 cores to -13.5 mv each.

3. Use 0 as the parameter for Multicore Power Saving

4. Use Interactive or Ondemand governor.

5. Use CPU frequencies upto 1.3 or 1.4 GhZ.

6. Use GPU frequencies upto 340 or equivalent

That's the kernel part.

2. ROM:

Using custom rom might not be that important because almost all roms available now are either stock or MIUI. So, it won't make a difference. Still some roms might be slightly better.

One rom that I found was Alba's Ultralite roms. These roms have been developed by a russian developer. The thing that's really good in these roms is that, the Ultralite series weigh around 600-700 MB and are totally debloated. So, lesser the bloatware, lesser is the memory consumed and hence, lesser is the battery consumed.

Another rom to observe is Dr. Ketan's Rom series. Many users are satisfied with the balance of battery life and lots of customisations.

Some other good roms are Alliance ROM, and Murat ROMS. There might be many more roms with good battery life. Users may leave their comment below and I'll add them.

3. Memory:

Yup, more memory means more battery. Many would disagree with me but, I tried it out and saw amazing results. I would suggest you to use Clean Master to clear cache, memory and check out your phone's temperature.

4. USPM MOD:

Xperiacle, an amazing developer[And my fav!] has developed a module called UPSM mod. Ultra Power Saving Mode, was found in Galaxy S5. He did an amazing job and has developed this module, which allows you to activate UPSM or Emergency Mode. Doing this, will limit you to basic apps such as Phone, Whatssap, etc and will prove immensely helpful for saving battery. This is highly recommended for an y battery savvy. There's also another Xposed module which reduces NLP Kernel wakelocks, thus making your phone sleep better. Download it here.

5. Reception/Signal:

Believe it or not, this is the part that takes away a huge toll on your battery. If you have bad reception, you ought to have a bad battery life. I saw the results myself. On full signal, my phone's battery dropped to around 98% after 6 hrs standby whereas on 1 bar signal, I found my battery to be 82% after 6 hrs standby. this is because, your phone tries to continuously searches for better battery.

6. 3G/ WIFI:

Personally I found 3G to consume much more battery than WiFi. So, it is advisable to keep it turned off while not in use. If you get a simultaneous screen on time and total 3G usage time of 5-6 hrs, you're great! That's the best you can get.

7. Temperature:

Your phone's temperature makes a lot of difference. Many times you might have experienced your phone's temperature shooting up like a volcano! Well it happens when your CPU or GPU is put under a lot of stress. For example while playing a high quality game. Many times it happens when some background app freezes. So, try keeping your phone a bit cool! I mean, always check if any background apps are running continuously.

8. Greenify:

Hey, I am not talking about afforestation or something! I am talking about a wonderful app called Greenify. Now, what it does is, it freezes the background processes and apps [which you select], and thus frees up a lot of memory.

9. Debloat:

Yup, lot's of apps on your phone may slow it down and deteriorate your phone's battery. Try removing apps that you don't use anymore.

Also, another thing I would like to suggest you all, is to keep reflashing your rom every 2 to 3 months. This would ensure less momory clutter and defragmentation. Also, it would keep your phone running smooth. Also, as you might already know, AMOLED displays consume much battery for bright colors and brightness level of the screen. So, it's advisable to use dark wallpapers. :cool:

So, guys these were some of the customisations I used to achieve the perfect balance of battery life and performance. If you have any more idea or trick to save battery, do post it below. We'll keep this thread updated.

Thanks! And do share this thread with others.
