I'm trying to improve my battery life, and these are the steps I made so far (I'm using stock rom, rooted, bootloader unlocked):

Installed franco kernel r199

Installed franco kernel updater pro to control kernel settings

Installed app ops and removed most of the location authorization from the apps

Installed gemini app manager to control autostarting apps like maps

Installed wakelock detector to control wakelocks

Removed some system apps like google play books

In my normal usage I keep screen brightness at 25-30%, GPS off,location off,bluetooth off,NFC off.

I'm usually in H or wi-fi connection when I use my browser

Do you have any other advices to help me to improve my phone's battery life? Or just some advices on how to use in a smarter way the app I listed like which permission remove to the apps or which are safe to remove from autostarting apps, thank you

Improve from what? If you're getting ~ 4-5 h SOT on 3G or 6-7 h SOT on wireless, and with ~0.5-1% / h idle then no.
[Nexus 4 General] Ziendal:
Hi, I have little problem with 3G battery drain, I know, 3G uses more power than Wi-Fi but.

On 3G I have maybe max 1.5h SOT, 3G/2G 2h-2.30h SOT.

When im stay in home for weekend and im connected to Wi-Fi network I got 4h SOT, with that same usage.

Im using Purity with HellsCore, undervolted, grenify facebook, radio .98

Any idea what I can do to improve battery life on 3g ?

Very useful post, but is this suitable for my problem?

My phone doesn't have wrong battery readings.

It turns off normally at 2%.

[Nexus 4 General] davidsteele1975:
2% shutdown is normal?! Mine shuts down a little lower.

Although the battery percentage is just an estimate... ;)
[Nexus 4 General] RASTAVIPER:
The only little lower than 2% is 1%.

So, no point discussing for 1% difference.

[Nexus 4 General] davidsteele1975:
LOL I suppose, but statistically it could be significant.

In the context of 21 mAh, it isn't. Although I'm sure I've seen 0% for a few minutes before the device shut down.

Today I reached 3 hours with a very light use of 3g, like 15 minutes, one hour of wi-fi, few whatsapp messages In my opinion my batttery life can be really improved, but is it really possible to get 4 h SOT on 3G? Because 3g drains really fast my battery, for example in 20 minutes of normal browsing on facebook or xda using dolphin browser I can lose 15-20% of my battery and the 3g signal is strong ...

I got 3h SOT at 49%..

It should be more. Because i played game at 42% until 22%, and that drain so much..
[Nexus 4 General] xenyz:
Yes, I've found it's possible on stock ROM with custom kernel. However I wasn't testing standby time, so my 4h 50m SOT on 3G was in ~9 h uptime. The longer the uptime, the lower the SOT.

And to previous post, I fully agree. It's worth trying out the MiRaGe kernel if you run AOSP/stock ROM.

For me Plsx ROM and Mirage kernel, greenify and underclocking your device. Im running art..

You could easily got 4h with 3G on..
[Nexus 4 General] bart.found:
Why underclocking if you can Undervolting? ;)
[Nexus 4 General] davidsteele1975:
Because underclocking allows even lower voltages? Or heat?

There's a point where underclocking doesn't help any more but that depends on workload and other stuff...
[Nexus 4 General] bart.found:
Yes... it's true.. but this way your phone will be slower too.. just undervolting performances remain the same of the original.. no compromise!

Imho underclocking is like driving a Ferrari with handbrake pulled... but it's a personal idea..

You can also use Faux Clock its especially for the faux kernel and you can adjust much more like color-correction and GPU clock ;)
[Nexus 4 General] captaindyson:
You have been given a link already, but to give you an outline of what the ROMs on that branch are:

A while back PSX was the only one and regarded highly by the community, it's objectives were speed and battery life, but over time as features were added it became bloated, so after a move to the new forum PSX branched off into PSX and PLSX (Pure Light Speed Experiment) with the objective of PSX being the fully featured one and PLSX being a more streamlined model. As development has continued though a new generation is now beginning with a new ROM currently in testing to be known as "Fat Lady" which will be fully featured, (but still fast) and ctffromm's own project "Velocity" designed to use ART only and contain the absolute bare minimum features aiming to be the bleeding edge on speed and battery life (and doing a good job if you ask me.)

(These are based on my observations of threads, if any if the PSX team deem the above to be wrong then please let me know so I can correct.)

I always used to turn off data when the screen off (using tasker). Since this kernel is mostly acclaimed for battery I thought to try it with data on all the time and I am so far getting similar battery life where i kept data off with other kernels.

Unplugged at 90 percent. Now its at 80 percent after 2.5 hrs stand by and 30 mins SOT. Loving the stand by time especially :)

Iv'e been using a nexus 4 for over a year now, and It feels like the battery is getting weaker over time.

Previously, the battery held on for a day over intensive use. Now I need to charge after only half a day.

Btw, I use an app called PowerTutor to check the battery consumption by different apps. Very useful, and much more detailed than the standard Android battery screen.

I'd suggest MiRaGe over Hellscore, personally I have surprisingly good results with latest MiRaGe (actually modded MiRaGe, naruKa, but either or) and stock ROM / Gravity Box.

Hells core is good, it just doesn't have the latest CPU and GPU governors like MiRaGe.

This and disabling the location polling in maps seems to have helped a lot so far. At least for when I'm not using the phone, so thanks a bunch for that. We'll see how it handles a full day tomorrow, it just seemed much better for the past 6 hours.

Also, is it just me or did any one else's phones not charge past 80% for the first few days? I just got this 48 hours ago, but I've charged it overnight 2-3 times now and each time I wake up with it at roughly 80 percent.

Android really needs to have an update that focuses on battery management but most of it relies on the kernel. For manufacturers locking down their phones, Google really needs to offer benefits to manufacturers that stay true to the spirit of Android. No more locked bootloaders, no more closed source proprietary drivers.

These manufacturers really need to hire some of the guys here on XDA. They often do a better job than their own employees working on $100,000+ salaries.
