Hey this is a thread for all the Resurrection lovers out there to discuss what Kernel goes best with Resurrection ROM
I've tried several Kernels by myself but couldn't come to a conclusion which is better in which aspects.
So lets discuss openly the pros and cons of each Kernel
If you have tried any other kernel other than CM9 and Siyah please put your opinions as well.
Nice post! I'd be interested to see the results from ppl as I just updated to latest 1.7 remix and this time have left the CM9 kernal. I did think about flashing siyah straight after 1.7 package but decided to give CM9 a trial first
Will report in a few days!

I'm a Siyah fan too but after reading few reviews considered to give a try with CM9 will see how it goes
I'm currently using the stock CM9 with 1.7 and found it to feel pretty good so far, messed up a little yesterday when the phone froze while playing a video.
Before freezing the phone had 50% battery after removing the battery and restarting, the battery had dropped to 15%
I'm still a bit of a noob to all this so go easy
When flashing a new kernel, do I just put the zip on the card and flash?
Or do I need to wipe anything first?
This is my personal opinion, not trying to put anyone down.
Okay tried CM9 Remix kernel for few hours and already fedup :\
I see no better battery life compared to Siyah kernel, in fact CM9 Remix Kernel had lesser support than Siyah.
Lets see;
Siyah -
CWM touch recovery (and full support)
additional cpu governors (lulzactive,smartassV2,etc..)
Overclocking upto 1.6
support for BLN(Back light notifications)
CM9 Remix -
NO CWM touch recover and some of the CWM features are not available
NO additional CPU governors
NO overclocking
NO support for BLN
So for me CM9 Remix kernel isn't the one.
as i have tried Siyah kernel already im going to give Abyss or some other Kernel a try and will update on how it goes
This is a really difficult conversation because there are so many variables.
1) Kernels - each one has configurations so you need to mention what governor you are using and any other mods that you have done to the basic kernal config. Or if you are using it stock without changes you could state that.
2) Apps - all of us have different apps installed and some apps make demands on the system when it is supposed to be "sleeping". Dedicated battery enthusiasts use CPU Spy and Better Battery Stats to try to figure out what is eating the battery all the time. Then they freeze those apps until they are needed.
3) Usage - I'm retired, so I play with my phone a lot....spend an hour a day just reading XDA. I must turn it on at least 30 times between charges. Others have to work, so they put it in their pockets and leave it alone for a while. Some folks play 3D games which consume power like crazy. Using phone data eats more power than wifi. A black background on your screen eats less than a white background... and so on.
So this is not a simple conversation. The more you tell about your situation, the more others can see if it applies to them.
(PS - I´m not talking much about my setup because I'm still on RR 1.1 with Siyah 3.0.1+. I´m trying various governors to see which works best - currently on lutzactive. I'm usually down to around 45% at bedtime which is fine with me.....If I leave the phone alone and just use it as a phone, I can probably go 24 hours.
Siyah: Feature packed, lots of fluff, but very nice options as mentionned earlier.
CM9: Basic, VERY BASIC kernel. Gets the job done and most people sync their base with it.
I personally use CM9 with Siyah, works great.

I totally agree with you.
I use my phone very often too. not to play games but to text, listen to music, and i leave the phone data connected always to use IM services.
I'm sure it must be same with any regular user.
I love to play around with my phone as in trying out new stuff on it
This time its the Kernels and OSs that im testing on currently checking Abyss Kernel and already noticed that the soft key lights should be turned on time to time by going to settings :\
will see how well it does in other aspects

Did you try Siyah with RR 1.7 before going to Abyss? What were your impressions of the usual kernels that you tried? Apparently 1.7 is working well for you?

I've been using Siyah with RR 1.2 and 1.5 and battery life came upto 8-10hrs
wanted to try a different kernel and chose CM9 Remix which was in the download section of the RR thread and it was an utter disappointment for ME (others might like it)
refer to my earlier post for results.
currently im testing Abyss and will update on how it goes tonight
which one is the best?

It depends on user. Im a heavy user and a need freak so CM9 Remix didnt do much good to me trying Abyss at the moment. Await for results
This is very useful and im waiting for updates
AbyssICS (2.6b)
Okay lets see how Abyss worked out for me.
After the utter dissatisfaction over CM9 Remix kernel Abyss was quite impressive with battery consumption.
there's always a BUT
1. the softykey lights were never on even though i change settings, it stays on till the phone display sleeps and even of you turn the screen on again the lights never come back :\
2. Settings -> Storage always keeps force closing and you cant see the stuff in the external SD card even by using a file explorer (root explorer)
3. I didnt like the screen which comes saying some official italian bla bla when you restart the phone that got a very bad design
soooooooo im switching to Siyah-v3.2b4 after seeing its all new cool features and i found a great article on how to get the best out of the kernel
ill share it here : http://forum.xda-developers.com/showthread.php?t=1369817

No tweaks, but the screen on time suggests that the phone has been on standby most of the time, with no Data.
I always tend to have a fantastic battery performance too when I leave the phone on standby, with no Wifi or Data use.

I used the stock cm9 for a while on v1.7 RR and found the battery to last quite well, decided to try siyah 3.1.2 a couple of days ago and day by day it is getting better but not sure its as good as the cm9 yet....gonna stick with it for now and see as it has more options.

Ok guys. I have to admit, I was about to give up on CM7 due to battery issues and what seemed to be memory leaks progressively making my phone lag more and more throughout the day. I have found something some of you may not be aware of and I wanted to share this amazingly helpful kernel with you.
Using x99, Scary, and stock kernels regardless of governor I seemed to maybe get 8 hours of battery life with moderate to heavy use. I am proud to say, using bcnice20's kernel I have had my phone on for 9 hours with 60% battery life today. This is incredible, even with lighter use on the other kernels I had NOWHERE near this amount of battery left.
Most of you may not have seen this kernel because it isn't posted. (as far as im aware) Let me help you out. First, go into your Market and download Kernel Manager. There is a lite version in there that is free. If you have an extra buck or two donate to the developer for making a neat app where you can download kernels in a convenient place by downloading the pro version.
What you will be downloading is called bcblend SIO tinyRCU kernel. I have not true VR tinyRCU kernel yet. Not sure what the differences are, if someone could elaborate that'd be appreciated.
Regardless, I find the sweet spot for this to be at 245MHz min and 1GHz max on Interactive governor to work really well. The phone does not seem to get laggier throughout the day and consistently performs well, snappy, and just way better than the other kernels. (No offense to x99 and Scary, I appreciate all you've done!)
Give it a try and let me know if you all have similar results! I have heard that AOSP gets less battery than Sense ROMs from people on this very forum, and this may be the kernel to put that little debate to rest.
Oh, and be sure you have the latest CM7. I am on 7.0.2.1 trying this out.

I have been using the x99 kernal and i have about 1 d and 12 hrs with about 45 % left.. I also have the calibrator apk from the market so it wipes the battery stat when im at 100%. and various other apps that deal with the speed of the sd card and what nots. So, me coming from the Hero is very happy with this phone...
Thank you for sharing your findings... THIS IS SO AWESOME !!!!!
That's amazing battery life. I can't seem to get that great of battery life on CM7 as compaired to stock sense roms. What calibration app are you talking about exactly? There are a few on the market.

Hello, Just thought I would post my stats using the new Starburst rom with Pershoot's Kernel. Getting great speed and the system runs very smooth but it feels like my battery is draining quite abit faster...
I have setcpu set as "OnDemand" 300mhz-1400, 256mhz when screen is off. Is this battery drain normal? Ran for 4 hours idle while working, then during break i used my tablet for about 15 min, idle another 4 hours and then after work I only got about 2 1/2 hours of use from my tablet before getting the 15% battery warning (79% to 15% in two and a half hours).
Before installing any TW rom and using Pershoot's older (non-TW) kernel with same settings I was getting atleast 4 hours after having the system idle all day while i work (10 hrs), this was with about 40%+ battery left to spare. Please take a look at my stats and feel free to give any suggestions to help me get more battery
The performance now is very good, but before TW i was getting about 150 less points in quadrant (2950ish)with the extra battery life. Also i dont let any apps run wild while idle and have gps,bluetooth,wifi turned off during working hours.
Quadrant Score, Starburst TW + Pershoot's Kernel Aug/9/2011 builds (score:3100).

Battery Stats, notice the steep drop at the end? Thats the only time I really used my tablet... about 2 1/2 hours, web surfing (14 hours 35min total on battery).

why is your screen on and awake bar completely full if you only used it for the last 2:30?
In GENERAL
Screen on time 8-10 hours
Standby time ~100-500 hours depending on whats on/apps installed.
No idea why it says the screen was on, it was not... And I had the unit on but as far as i know there isn't a sleep option so the unit was awake but not being used.
If you know of a sleep option please let me know, thanks for your reply
Yeah I'm still testing this exact rom/kernel combo and there is something up with it.
On a reboot, does the battery level go up? Does it stay up for a little while then drop back down?
Also have you done a battery calibration? If so, how?
I'm just trying to narrow down what could be causing the problem. I'm no dev by any stretch of the imagination, but for some reason I really want to find out what is causing this. It doesnt seem to affect all machines so in finding the simularities of those that are having this issue, we can squash this bug....
I was using this combo and my google music kept force closing.

it should goto sleep automatically, and if screen was off it should be indicated as off. maybe something is wrong. im currently on pershoot's kernel as well and have had some issues with battery calibration (reporting bogus stats).
i think pershoot is looking into the issues on his thread.
im using 10.1-Wifi, Touchwiz UX (OTA, GT-P7510)
It's a kernel problem. Try going back to stock or an older version of pershoots.
It'll be fixed today from what I've read.
Late last night reinstalled Starburst with its original rom, after my 10 hour work day it still has 95% battery left (after some galaxy on fire 2 during my break), hella lot better than it was yesterday.
I will wait for Pershoot's revised kernel and test it out again. And thanks again for all the devs making custom roms and kernels! Much love to ya! <3
*Stock Starburst kernel is showing my screen being off (when it is off) and my system as not awake when screen is off under battery usage in settings

From what I've read, he claims there is no problem with the kernel, the problem is with the user. We havent calibrated the battery correctly according to pershoot himself. Problem is, I cant figure out the secret to a correct calibration process....

Flash Starburst or stock rom then charge your tablet 100%, once your battery is fully charged flash Pershoot's kernel.
I have not tried this myself but from what I have read it works, right now im happy with the performance on stock Starburst kernel, quadrant is at 2300 compared to Pershoot's 3100 but its running so smooth I cannot notice the difference. Going to wait for Pershoot's reworked kernel and then flash it, I gots to have my voodoo!
Update:
Today I reset my battery, and installed Pershoot's kernel. I'm still getting battery drain, used for 5 min this morning and its down to 80% (just browsing web)... Also my clock got stuck at around 5:08am and my alarm did not work this morning until i turned my screen on. After I installed Pershoots kernel alot of apps were acting up and not running properly but after a reboot my clock and apps started working as normal.
And I have to hit/hold the power button like 5 times to turn on the unit now. Going back to original Starburst for now.

Hi Guys,
What would ye recommend for the best kernal to put on with AOKP? Guess im looking for battery life rather than hugh performance, although i dont want it to be really laggy.

huh??? theres only one kernel that can used for AOKP and if you're using AOKP you're running it. you gotta do some reading up bro. AOKP is an ICS rom. but anyways. even if you weren't running AOKP there's only one kernel developer (pershoot) so far for the galaxy tab 10.1.
You always have the option of using a popcorn kernel. Not sure how that compares to the stock kernel or pershoot's kernel, but since it's really the only other option, I'd say give it a try. Best with melted butter.
I experienced really fast battery drain on pershoot's kernel. I don't have evidence to prove it and at the same time don't want to diss pershoot's work and there is a big chance that I might be wrong but that is what I witnessed.
that's why I stuck with stock based kernel's right now.

The popcorn kernel sucks until rooted and modded by heat.
sorry couldn't help myself like you couldn't.
As far as seriously, it all depends on how you configure and use Pershoots kernel as to if you'll experience lessened battery life enough to be bothered by it.

At this very moment we only have preshoot's ICS kernel available for GT 10.1 since he is the only one involved in kernel development but we would all love to see more developers jumping into the Kernel Wagon!
But sincerely speaking ......... I think preshoot's kernel would give anyone good battery life if they do not have over-clocking on.

Pershoot's ICS kernel or HC?
I always had good battery life with Pershoot's kernel on HC. Actually, not just good - great.
However, so far, CM9 is a poor battery performer. I've got a suspicion why (I think it's the same wifi power management bug I experienced on the Galaxy S II with some firmwares) but I haven't had time to confirm.
If it's not the bug I'm thinking of, it'll be a ***** to debug - high drain despite good deep sleep percentages is really difficult to solve. (Basically, something is failing to power down in deep sleep.)
Maybe more info this weekend when I have time to get a kernel tree synced and building for the 10.1.
I think there were two reasons no other kernel developers have done much with the 10.1:
1) Until Heimdall supports the 10.1, developing kernels for it is a bit of a pain in the ass (Edit: If you have a retail Tab - the I/O Tabs had fastboot...)
2) Pershoot does a damn good job - if it ain't broke, don't fix it. There's only two features I miss that aren't present in the kernel, and they weren't worth the hassle of maintaining my own fork.

i get good with battery life on CM9 (for tab 10.1). especially so with the new wifi module coming.
this is with no sync on (using new module):
45 hours - 93%
with sync on, just a bit less then that.
another person with 3g + wifi always on (using new module), about 14 hours, lost 13%.

New module? Holy crap, I just revisted your sources. I guess ICS doesn't like the legacy BCM4330 module.
That explains a lot...
45 hours to 93% is consistent with what I got with HC. Right now, I'm intermittently (Sometimes life is great, but at some point it behaves like something is not properly powering down in deep sleep and remains that way until reboot - it can take 2-3 days to break in some cases, in others it breaks almost immediately.) getting around 1%/hour standby which is poor for a 7 AH battery on a wifi-only device (esp because I KNOW it used to do much better). I suspected it was wifi power management, but it's apparently not the specific issue I thought it was (even though it has very similar symptoms)... (As I said - I've been so busy I haven't had time to mess with it myself, I was going to this weekend but now it looks like I'll be changing track.)
I just rebuilt, time to flash!
BTW, which remote do you pull Dmitry Schmidt's patches from? Last time I tried to find upstream for that stuff I failed.

You sir, flat out ROCK!
So far, after repo syncing, rebuilding, and flashing last night - the new wifi driver seems to be doing the trick. I'm now seeing battery life consistent with what I used to see on HC. Went to bed at 95% and it's down to 94% now. Previously, I would've lost at least 10% in that period of time.
Of course, it needs a few days to shake out - previously it took as much as 2-3 days before it flaked out, although even pre-flakeout I don't think I ever saw CM9 on the Tab do this well in terms of standby battery.
I spoke too soon, and it turns out I was wrong with my initial guesses as to the nature of the problem. I haven't been as rigorous with the Tab as with my main devices.
It turns out it is exhibiting the same Broadcom bug with frequent wakeups that I777 UCKK6, I9100 XWKK5, and a few Infuse leaks had - See http://forum.xda-developers.com/showthread.php?t=1308030 , it's the first entry in the list there.
It's annoying because it's a combo of system and kernel - on I9100 and I777 it was usually caused by system changes, but sometimes would surface if a kernel developer started mucking around in the BCM4330 driver...
In the attached zip is:
A dmesg dump
A shot of the battery screen (less useful than I thought it was now that the problem is not what I originally thought it was)
A dump of /proc/wakelocks
A Wireshark pcap of the problem - note the protocol 0x886c packets happening at 1 Hz
Hello,
I have done nothing to my Nexus 4 so far but I recently noticed that the battery isn't that good. I heard that the Franco Kernel might give more battery life. I don't play any games I just use it for texting, surfing and listening to music. Is the Franco Kernel good for my usage then or would you suggest another kernel?
I found the thread where I can download the Kernel but what is OP, Milestone and Nightlies? How do I flash this Kernel? Do I have to root? I couldn't find any HOW TOs.
Hope you guys can help!
Thanks!

Yes you will need to unlock your bootloader, install a custom recovery, and root. Then you download the franco kernel zip and flash it through recovery.
OP = original post
Nightly = means the latest build (they are compiled every night, and may have bugs)
Milestone = usually means a complete version (stable releases)
Milestone = stable version
Nightly = newer version may contain bugs
U first need to root your device and download the Franco kernel zip and place it in your extSdCard. Once rooted goto recovery (volume up + home + power) select install zip from external card. Browse to file select then install... And enjoy...
Make sure u know wot you doing. Read first n read alot before any action else you may brick your device.
:*: Neebi :*:
also you can buy the app and it install the flash by itself,
i guess you still need to root
since you don´t game it`s weird to have bad battery, try greenify

Hello,
I have done nothing to my Nexus 4 so far but I recently noticed that the battery isn't that good. I heard that the Franco Kernel might give more battery life. I don't play any games I just use it for texting, surfing and listening to music. Is the Franco Kernel good for my usage then or would you suggest another kernel?
I found the thread where I can download the Kernel but what is OP, Milestone and Nightlies? How do I flash this Kernel? Do I have to root? I couldn't find any HOW TOs.
Hope you guys can help!
Thanks!

okay I see thanks!
Well I don't play games but I often use 3G Service and that usually drains A LOT of battery. I just want some more screen time when using 3g or WiFi. Does the Franco kernel change that?

Kernels don't do that.

Your apps will make the biggest difference. Stop apps causing wake locks such as Facebook and anything with auto refreshing/push alerts.
The biggest benefit for me of using Franco is adjusting color profiles. Once you try other settings, you'll never go back to stock colors.

Kernels don't change this I'm afraid, and 3G will always use pretty much battery. Wifi on the other hand uses nearly nothing.
If you say you're not a heavy user then Franco's Kernel will be a good one for ya. As it contains hotplugging (meaning it will make the device slower if it's not used but fast when you want it to be)
Slower = more battery conservation.
Also let's you underclock your device. As for example you don't play games so you don't want it at 1512Mhz, you can run it at 1ghz and the time your screen is off lock it to 384Mhz (or a bit higher) which again makes your battery last longer.
It comes to a small downside, that kernel comes with its own app which costs a bit of money. But it's very much worth it as you can tweak it just as you want.

"unfortunatly" you need root before you can flash this. But there have been very useful links in previous posts, try those!
Then if you've done all that, look into Greenify. You'll notice a difference when using it, trust me
enjoy
Hi easygoingx! i wouldnt recommend you flash franco for now. I have been using franco for 2 months , i purchased the app and everything but lately it's comsuming a lot of battery! it drained my battery a lot with last updates i was getting crazy!
if i were you i'll flash trinity!
i've turned on my phone 30 min ago and my battery is in 98%, with franco it would be by 92%
but if you wanna flash ,first root your phone and put a custom recovery (cwm or trwp) and download the zip to your nexus 4 and flash it from custom recovery.

That's definatly not the cause of Franco, but most propably some other apps rogueing. Try Greenify.

It's maybe the case with nightlies on particular devices.
I'm not the one to judge on that but on Milestones (Milestone 2 aka latest) there is nearly no battery consumption in idle and I've used Franco since r102 (newest is r136)
In the including pic I had flashed Milestone 2 from Franco, then afterwards changed some values in the app to my liking (aka max freq 1350, min freq 384 etc...) and then left it be for a couple hours and look at the result. Lost maybe 1% over nearly 4 hours. If I leave it on generally over night on wifi + data sync enabled, I lose about 2-3% (depending on the sync times ofc). I sleep approx 6h a night btw
Also feel free looking here and see all the positive comments of people and their battery! (also one of the most active and responsive forum topics around)
Therefore I highly recommend Franco!
Oh now I understand these terms. Thank you guys! I'm considering flashing my phone and change the color settings. I'm really annoyed by those washed out colors!
You know what really annoys me? That when I am on 3g and my screen is locked IT DRAINS my battery SO MUCH. Isn't there any ROM/Kernel that fixes that? I mean the S3 has this even on Stock and unrooted....
Hmm... Somehow my phone gets so warm lately.... I'm kinda worried.

They sure are.. but you can take a pick from like 30-35 presets (using Franco's preset myself). Trust me, the result is just... awesome! (if you prefer AMOLED (cause you refered to an S3, you can also change colors to that, it's in the spreadsheet here (check kernel column to see for your chosen kernel))

I doubt that there is a way around the battery drain with 2G/3G/3G+ but just having a different kernel will do miracles concerning battery life. Always feel free to ask this in the thread, maybe someone has a "solution" to your issue.
I don't know how often you're without wifi. But just make a tasker task like I have:
- "if wifi connected (=state)-> Data off"
- "if not wifi connected -> Data on"

Don't worry about it too much. The nexus 4 is known for having bad thermal handling inside the phone (read this) but it won't harm your phone in any way.
If however you are still worried just download the kernel and go to "Voltages", just press-25mV a couple times (I recommend 3 or 4x). This will reduce the heat generated from your device. (Yes your device can handle this, even more but I'm not responsible )
Another thing is what is getting hot inside your device, battery or CPU? Franco Kernel Updater (app) has Device Monitor which let's you check the CPU temps. If the CPU gets warm/hot too often or too fast, just reducing the max CPU frequency can help you out (1.5Ghz is "too" much anyway, you'll be fine with a couple steps less )
Hope this helped If you have more questions that I could answer, just quote me
Hello guys. I know that this is a very common question not just in OnePlus 2 forum. I read some posts of this, tried, but no success. So far I've tried couple of ROMs but battery life is so disappointing. Best shot was RR ROM 8.1 official with BB kernel installed. After system and kernel installed, I've done a wipe of data. I wanted to make sure there is nothing except system on my phone. After that, all necessary apps I use. That was operating very good in few days. But recently, out of nowhere, battery life is awful! Over the night, with no use and battery saver turned on, I loose more than 20%! I know that I haven't downloaded any additional apps after first days of installation, I haven't changed any settings since first day... I added fingerprint lock 2 days ago and yesterday I turned it off. So What is going on??? Phone is not overheating, seems like there is nothing in the background running to drain battery.
If you know what could cause the problem, it would be very helpful. But I'm also opened for installing a new ROM, kernel...
Who is here with good battery life? Gimme some advice! Btw, I don't care if it's N or O, or anything as long as it's operating well, reliable and no bugs. Thanks!
That's probably a battery issue, install AccuBattery then see how much health your battery have(requires few charges).

I reached (haters gonnah hate) best battery life on lineage 13 with boeffla kernel (zanezam's uber builds, use some battery safe profile from profile thread or make your own), amplify, greenify (optimized accordingly to the corresponding thread, with xposed) and NO GAPPS. Get about 3 days with SOT of 2-4h or a sot of 6-9h on 1 day (on an old oneplus2, no gaming). You can also use dualbootpatcher and a second, battery optimized (but lagging) ROM so you can switch when you can't charge your phone for a longer period of time.

I did, really awesome app but I'm not sure that I understand what is saying to me. And I don't think that is battery issue because before this I had a really good battery life. I'm sure that if I do a fresh install of new ROM, battery life will be great but only for few days.

Can you explain this please with simple phrases? How was the performance? Do you use it now?

I personally use AOSiP with NGK and I get 3-4 hours SOT in 2 days, give it a try if you want.

Forget everything with dualboot patcher, you would probably mess up your phone.
For everything else, use xda search. Seriously, you only have to type the apps i suggested 1:1 into the adress bar and you will find it! If you are too lazy for this, unroot and go back to stock.... seriously...
Edit:
Yes, i'm using this now (lineageos13) with a self compiled boeffla kernel (uber 8, camera focus fixed on 6.0.1 roms), greenify, amplify (own build), xposed (needed for amplify, greenify works better with it) and no GAPPS (= google apps--> no playstore, youtube, etc--> draining battery as hell, idk what they are always doing in the background...)
My boeffla profile: 3 cores 1250mhz max, big cores disabled, battery extreme governor, system and my apps (whatsapp, telegram, 9gag, browser) work fluently (they start up a very little bit slower than before).
Battery profile is same but with 2 cores 675mhz, still only few microlaggs (you have to disable all animations in developer settings), internet browser is slow (use a lightweight browser, such as firefox focus) apps open up slower but aside from that the phone is usable. If you're interested in the kernel and my profiles, please tell me (you still have A LOT of work to do by yourself, such as setting up amplify and greenify, disabling (system) apps you don't need, adjusting everything for your needs, deny unnecessary permissions on app ops xposed, etc).

AOSiP it's a rom - Android Open Source Illusion Project
NGK it's a kernel - No Gravity Kernel
SOT - Screen On Time

Results can vary. As someone who flashes way too many ROMs - its an addiction - I currently use crDroid Oreo as my daily. I also flashed the blue bolt kernel. This seems to give me good battery. I do have a rooted version of the stock ROM I flashed in twrp backup. Just in case. With crDroid also backed up I can move quickly from one to the other in about ten min without losing all my settings. It is a good idea to occasionally do a fresh backup of one or both since apps added or deleted or updated and any changes you've made since last backup will not be kept otherwise.

Do you know dualboot patcher (google it )? Very nice opportunity to have multiple roms installed on the device (which even share the data for specific apps--> u have all your wa chats from one rom on the other, directly after reboot). Wouldn't recommend for people who can not restore a backup over adb (unexpected things can happen, but way better than always saving and restoring a backup)...

If you don't mind for a worse looking screen quality, you can use terminal emulator (with root), do a backup in TWRP(ALL partitions!) then type (hit Enter after each line):
"su" (grant root if asked)
"wm size 720x1280" (for 720p, it looks about the same as 1080p, u can also use 480x854)
"wm density 300" (200 for 480x854)
Then u can lower your cpu frequencies until it lags. (and disable system animations, my phone works fine at 480p with 2 cores at 768mhz max freq) will post sot/running time (without charging) when i have the time to test.
