Here's one advanced tip to noticably improve battery life on almost any Android device
Compared to the feature phones of old, the smartphones of today are profoundly more powerful. You know that. The industry has made incredible leaps forward, and we enjoy devices that are far more capable in all areas... but one. Battery life. A tougher nut to crack than we'd all like.

Of course, there are all kinds of tweaks you can apply to better the endurance of your device, and most of them can be taken care of by even novice users — at least so long as they know where to look. For today's lesson, however, we'll embark on an infinitely more perilous journey that simply isn't for everybody. It's not that it's incredibly hard to apply this tweak and reap noticeable savings in power consumption, but it does require root and a custom recovery, both of which are relatively simple, but still advanced, operations nowadays. For the purposes of this tutorial, we're assuming that you've got these two out of the way.

The guide here is nearly universal, and will work with most popular Android devices. In case you're curious, we'll be showing you how you can easily under-clock and under-volt your CPU (and GPU) on demand, and set a different CPU governor that ensures the most is squeezed out of your battery pack. Keep in mind that newer devices likely already include one such tweak as part of the software they come with, but most don't go as far as we're tentatively suggesting you could.

As with any modifications, there's always some risk involved when messing with your device, so we suggest that you perform a Nandroid backup of your system in case things go south. Better safe than sorry!

Do you mean can't because they don't know how, our can't because their phone has a locked bootloader and no root. I'm in the second group. I've been utilizing the awesome custom kennels and roms of the talented devs since the winmo days. Had nothing but custom on my S3. But, the Note 4 and now my Note 5 are locked down tight. While I'd still like to see them unlocked, the Note 5.especially, is so fast and smooth that it almost makes me not care.

"But, the Note 4 and now my Note 5 are locked down tight. While I'd still like to see them unlocked, the Note 5.especially, is so fast and smooth that it almost makes me not care." So an Android fan who has an obvious dislike for Apple is starting to sound like an iSheep... Interesting. ;p Of course I expect much hatred, insults and patronisation for this comment.

In what way? I still really hope for root and an unlocked bootloader. I paid cash for the phone, I should have full control over it. It's just that I the past, they're were notable differences between my S3 stock and with custom kernel. I can't see that the Note 5 could be any smoother or faster, but it could gain great features. As for my dislike of Apple, the only thing I dislike is their business practices, which are anticompetitive. Just because I recognize that other devices are better than Apple products doesn't make me an enemy.

Fair enough. I also think Apple are too locked in and their "We're right" attitude is getting a bit old, they're starting to fall back without Steve at the helm for sure.

I think Apple has progressed without Jobs. Cook isn't so arrogant as to think he knows what the user wants more than the user. He's willing to listen to the market, and if Jobs were still in charge, you'd be looking at an iPhone 5sss this year.

"the Note 5.especially, is so fast and smooth" Until you open more than 5 apps when the RAM monster kicks in or when TouchWiz becomes MolassesWiz.

Try opening 5 apps in other phone then tell what happened...are they still runing in background?

I'm also one of those few. Done with my Z3C, and I'll be doing this with my galaxy s7 when it comes out ;-)

The best way to get better battery life: avoid phones with gimmicky QHD screens; 1440x2560... and the battery drains like hell.

Custom recovery is the first thing I flash on my phone. Don't buy any Android phone that doesn't have a modding scene, to me it's a huge requirement. Despite what the fandroids say, Androids updates are a joke, if you want the latest built, custom roms are your best bet. Which is why I stick to Nexus phones. Mods like these change the entire experience.

Same here, if the phone isn't supported in the mod scene, I aint buying it
