Reboots and Battery %

Hello everyone posted this thread up so that I can get to the bottom of the random reboots and strange battery % eny feed back would be great thanks

I have been on viper Rom for a few months now. its been a great rom until I changed the Kernal in the tweaks it just hasn't been the same . random reboots and battery % has been all over the place jumping from 80% to 10% after reboot. I have kept to all the default settings in the aroma installer no uv and no oc. the phone works no problems when on the charger witch makes me think its a battery issue. I have tried cleaning the battery grounding pins and placing a bit of card at the top of the battery with no success I am at a loss here. feed back would be great thanks for your time

Hi,
Why not restore your nandroid backup?
Put the phone back to where it was before you had the problems.

Hi,
Well , you won't do that again...
Reflash the ROM.
Choose the settings with the original kernel.
The rest of your data and settings should remain intact.

You best believe I won't hahaha.
I have reflashed the Rom a few times with default kernel still no luck thanks for your time with this its much appreciated.
I have seen a few posts about cpu screen off in the tweaks do you no anything about this bit of a noob when it comes to setting values and what they do

I think it was anthrax or pyd am not sure. The kernel at the moment is bricked I can use the phone when on the charger as soon
As I disconnect it 5 mins or so it will reboot with a different battery % .
Its so frustrating honestly ready for throwing the phone off the wall to see if that helps

Again thanks for your time.

Just flashed kernel kept to all the default values. When the phone reboots it had 100% I was on the phone for about 5 mins on the internet to check these posts then it reboots again aaarrrrgggg the battery now shows 75%. The reboots seem to happen when on internet. Youtube. Facebook. Am going nuts here lol . Thanks anyway for that.

Hi,
OK
You should think about saving all your data, wiping the phone clean, and start again from scratch with the good kernel.
If that fails, then, you should look for a new battery.

My GF and I have the same phone, and hers has the bone stock ROM from TMO/HTC, and she's been getting a lot of strange reboot/battery drain cycles going on lately. I've got an older ARHD ICS ROM, and I've had no trouble at all with it.
Her phone went from 50% to 8% after a reboot last night, and after about 10 hours on the charger, it's only showing about 75%. If she has any more issues, than I'm going to put the latest ARHD ROM on it and call it good.

Only new battery I had same problems, a new battery solved it.

Have the same problem. Is this a Rom/Kernel bug or do I need to buy a new battery?

Which rom is best for battery life?

I recently purchased this phone, and have been appalled by the battery life, it's atrocious. I also seem to have a bug with Maps that keeps draining me, even though I don't use any location services, etc. So now, I'm going to install a new rom, and see if my battery improves significantly. My question is, which rom is the best with battery life? There is no point in having this fancy phone if you can't use it because the battery is dead before you even get out of work and it's just been sitting in your pocket -_-, this is what happened to me.
Right now I'm downloading CleanROM 6r2, latest build. I do intend on flashing it later tonight and testing how the battery level is, and if it still declares I'm roaming when I'm obviously not.
Right now I'm stock, rooted and bootloader unlocked I have no put any roms on the phone as of yet, but battery is terrible regardless. My brother has the same phone, same carrier and same battery issues albeit, not nearly as detrimental as mine.
Thanks in advance. If CleanROM is the best with battery life thus far that would be great. I'd like to try 4.2.2, but hear it's got terrible battery life?

Sorry to be the first to say that "what's the best Rom" is frowned on around here
You really need to find out what works best on your phone through reading and testing.
However just to point you in the right direction. clean Rom has never let me down and synergy can sleep like a baby
Finally I'd think it is safe to say aosp Roms will never compare to battery on tw
They can still be very good but for your purpose you may have better luck else where.
God bless the American people

You could just freeze maps if you are not using it.

95% battery life is controlled by the Kernel, not the rom. The other small 5% can contribute to battery such as odex vs deodex, quick boot up. Also, I'm not going to bring in user settings control such as screen brightness, apps sync intervals etc.. I'm talking about if we have 2 devices with the exact same setup, the kernel is where it makes a diff in battery saving.

This ^^. I thought about it, but its just too big and intrusive.
Besides, my phone shouldn't die idle in my pocket. My brothers AT&T S3 stayed on for 3 days without usage, mine died in under 8 hours.
Anyway, I do understand that "what is the best" is frowned upon. I've been around a little while, I'm just not very active. I really wanted more of a general answer regarding user feedback with certain roms, or experiences maybe.
Also, regarding the kernel that is news to me, I didn't know that. Thanks for the information. I guess I can redirect my search to a kernel.
I do want to report though that my battery life has improved significantly I think than what it was before. Granted the rom was just installed today and has already died, I used it very heavily today though as opposed to the very minimal usage that killed it previously. I wont for certain until I get back to school and have it idle around for a while.
I'll check out Synergy if I'm not impressed, although CleanROM right now has fixed the MAPS issue I was experiencing. It no longer shows it as something that's killing my battery and I left all the settings the same as they were. So that tells me it was an obvious bug in my software specifically or something of that nature. So far so good.
P.S., did you personally have better life with Synergy over CleanRom?
Btw, I have always maintained a modest setup on my phone that should improve battery life. Low screen brightness, no WIFI unless I need it, no mobile data unless I want it or need it. I never checked on sync intervals though, I'll have to do that.^_^

It all depends on the kernel and its setting. My experience so far is that I overall get good battery life with LeanKernel, GalaxyKOR, KT kernel regardless what ROM I use. I also use DS Battery Saver in Slumberer mode. At one point after fully charging my phone I left the screen off for 8 hours woke up it went from 100 % to 97%.

I'll check out DS battery and some of those kernels. What is your primary ROM? I'm digging CleanRom right now.

I recommend just trying diff roms and diff kernels and just see what works best for you. I am currently using Jelly Beans build 13 with LeanKernel and I have really good battery life.

Went ahead and flashed lean kernel v 1.10 now my phone wont boot up. I get 2 Samsung Galaxy logo's then it turns back off. ?
In the process of restoring a backup I made. Is there something wrong with the way I approached things? I simply put the zip on my sd card, and flashed it in CWM

So my backup saved me. After that I went through file directory for leankernel and seen nothing about 1.10 haha, so I guess I downloaded something wrong. Now I'm going to try flashing 2.1 will report.
Edit: So, I did flash the wrong kernel on accident. New 2.1 kernel worked for me this time.

Leankernel has an TW and AOSP version. Good thing you did a backup.

Download Better Battery Stats to better track down your wakelocks. Besides that I don't really think there is anything that can be significantly improved going from ROM to ROM. 4.2.2 ROMs are starting to rival TW in terms of battery life. The biggest battery killer is low signal. If you are in a building or on the edge of a service area having your phone constantly switching towers or going from 3g/4g really eats up the battery.

There are Touchwiz and AOSP versions of Lean Kernel. Look in the original development section and flash the appropriate one for your ROM.

I purchased the 7000mah battery and lost my data connection when I was away from my house. I asked around and it's a known bug, but a lot of people don't care because the battery lasts so long. I have the 4200 hyperion and 4400 Anker and love the Anker... as a back cover, I use Seidio's cover because the ones that come with Anker and Hyperion are crap.
On my phone, I have used almost all the TW and AOSP ROMs.... For me, CleanRom gets the best battery. I am not into messing with my performance settings, I don't find it helps all that much and causes more problems than it's worth. With the Anker battery, I go through about 35% battery per day... if I let my phone get down to 5% battery life left, I usually have somewhere around 6 hours of screen time. For me, that's plenty.

[Q] Battery calibration when switching ROMs

Just wondering if there was a "best" way to make sure battery is calibrated after flashing a new ROM to ensure the best battery performance for that particular ROM. My procedure of late has been to just let the battery die then charge to full and wipe battery stats. Any suggestions or is this even a necessary or worthwhile step when switching ROMs?

hm.. if I switch to a new rom, i download the app "battery calibration" from the store and plug my phone into power.
if my battery is at 100% the app will give you a signal and delete the old battery history.
not sure if this take any effect, but I never get disadvantages by doing this.
you can find the app here:

Best Rom\Kernel Combo for SOT and Performance?! POST PICS!

Hey guys … we've had quite a bit of development in a very short amount of time since release. There are some very talented developers out there and a dedicated number of people making our already great phone even better.
So, I was curious to see at this point what Rom\Kernel Combo everybody is running to get the most out of the battery while maintaining performance!
Sound off on which rom\kernel combo you're using and post battery life screenshots if you have them!
Thank you to the developers that make this happen, we couldn't have gotten here without you!

I guess there is only one stable rom xXx

SOT varies and depends on your usage.

Xxx+cleanslate

If you want a balanced kernel with a really good battery life, you should go with franco kernel. I achieved very good stand by and screen on time, even on the currently battrry-buggy OxygenOS 5.1.8. And if you want a light customizable ROM with quiet a few goodies, go with Renovate 3.2.

Is that stock options with Franco?

If I pick up my phone and use it all day in bed when I'm under the weather or when I'm home for the day with nothing to do I can get 7 hours of screen on time with constant usage at half brightness. When I am at work and have the phone with me and do a little gps etc I can get about 6 hours. It all depends on your usage and also your cell signal. The worse your signal is the faster it drains the battery. The more GPS you use the faster your battery dies. It doesn't matter which kernel I am running, (I'm currently on stock 5.1.8 with Magisk, Xposed & ElementalX) battery life is pretty much the same.

if you won't stop to believe that rom and kernel are responsible for SOT and standby drain you will never be able to 99.9 control and manage your battery usage.
it's all in user space as long as there is no know battery hog (know bug) in either rom or kernel.

Best battery saving kernel?

I'm looking for a kernel to use that will net me the longest battery life and idle times. Would love to hear people opinions/experience with kernels and kernel settings.
Please share settings and any info on how you achieved such good battery life

I will probably get yelled at by someone for this but, most battery savings is in what apps you have installed and how bad there are requesting wake locks. For me. I use flash kernel because he takes upstream updates to kernel.

For me the "Advance Battery Optimization" did the trick!
In combination with Francisco Franco Kernel, my battery life jumped
two folds. And of course as mentioned, it does depend on apps installed
and your habits.

I personally prefer Smurf kernal. For me and my usage, it's given me a great balance of performance and battery life. But it all depends on your apps and usage. Everyone is going to have different results using the same kernal. Too many variables to differentiate getting the same results as others.

Averaging between 5-9 hours. Really depends on usage, what apps I have installed. Even how hot it is outside effects it.
